A pair of support rods 6 are fixedly installed in the middle of the upper end of the device base 4, an adjustment plate 11 is arranged above the two support rods 6, a sliding member 12 is fixedly installed on the front side of the adjustment plate 11, a square groove is opened in the middle of the sliding member 12, an active roller 1201 is rotatably installed above the square groove opened in the middle of the sliding member 12, and an auxiliary motor 1202 is fixedly installed on the side of the active roller 1201;

The upper end of the device base 4 is located on the inner side of the support rod 6 and has two adjustment grooves 22. The upper surface of the device base 4 is fixedly installed with an adjustment frame 7 at the position of the adjustment groove 22. A pair of mounting plates 21 are fixedly installed on the lower side of the device base 4 at both sides of the adjustment groove 22. A stabilizing rod 20 is fixedly installed between the two mounting plates 21. A stabilizing frame 25 is fixedly installed on the outer side of the mounting plate 21. The stabilizing frame 25 is a "T"-shaped metal component. The front and rear sides of the stabilizing frame 25 are rotatably installed with limiting wheels 5 and auxiliary wheels 8, which can fix the upper cable reel 13. The auxiliary wheel 8 is rotatably installed on the upper front side of the stabilizing frame 25. The limiting wheel 5 is rotatably installed on the upper rear side of the stabilizing frame 25. An adjustment spring 26 is fixedly installed on the lower front side of the stabilizing frame 25. The inner cavity side wall of the device base 4 is fixedly installed with a spring positioning plate 18 at the position of the adjustment spring 26.

An electric push rod 24 is fixedly installed in the middle of the lower side of the device base 4, and an adjusting member 23 is fixedly installed at the output end of the electric push rod 24. An arc groove 19 is opened in the middle of the adjusting member 23, and an adjusting rod 17 is arranged at the position of the adjusting groove 22 located at the arc groove 19. A pair of lifting grooves 16 corresponding to the adjusting rod 17 are fixedly installed on the side wall of the inner cavity of the device base 4, and a support member 15 is fixedly installed at the upper ends of both sides of the adjusting rod 17 at the position of the auxiliary wheel 8. An arc groove is opened on the upper side of the support member 15. When the support member 15 rises, the arc groove on the upper side fits with the middle of the auxiliary wheel 8, so as to provide a certain support to the auxiliary wheel 8.

A protective film is provided on the outside of the auxiliary rotating wheel 14, and the protective film is a rubber material component. When the cable drum 13 is fixed, the rear side of the cable drum 13 contacts the auxiliary rotating wheel 14. When the auxiliary rotating wheel 14 rotates, the entire cable drum 13 can be rotated synchronously, so as to facilitate the retraction and release of the internal cable.

The adjusting plate 11 is located at one end of the supporting rod 6 and is provided with a plurality of adjusting threaded holes 1101 in a circular shape. The supporting rod 6 and the adjusting plate 11 are rotatably connected via the rotating shaft 1. The side of the supporting rod 6 is located above the rotating shaft 1 and is provided with a positioning bolt 10 via a thread. After the positioning bolt 10 is removed, the adjusting plate 11 can be rotated at an angle inside the supporting rod 6. When the adjusting plate 11 is rotated upward, the cable reel 13 can be conveniently pushed between the supporting rods 6. After that, the adjusting plate 11 can be rotated toward the front side of the supporting rod 6. The adjusting plate 11 can be fixed by using a bolt passing through the adjusting threaded hole 1101 on the side of the adjusting plate 11.

Three driven rollers 1203 are rotatably mounted on the lower edge of the square groove opened in the middle of the sliding member 12. The driven rollers 1203 can play a role of assisting the rotation, so as to facilitate the pulling out and recovery of the cables.

The front side of the device base 4 is an inclined slope structure. The upper end of the device base 4 is located on the front side of the adjustment frame 7 and a storage groove 9 is fixedly installed. A slot corresponding to the cable drum 13 is opened in the middle of the storage groove 9. The cable drum 13 is aligned with the slot on the upper side of the storage groove 9 and pushed, which plays a certain preliminary positioning role for the cable drum 13.

A pair of limiting members 701 are fixedly installed on the inner cavity side wall of the stabilizing frame 25 at the position of the limiting wheel 5. When the cable reel 13 rolls to between the limiting wheel 5 and the auxiliary wheel 8, if the cable reel 13 rolls toward the position of the limiting wheel 5, the limiting members 701 will contact the upper end of the adjusting frame 7, thereby providing certain support to the rear side of the stabilizing frame 25, so that the cable reel 13 is fixed between the limiting wheel 5 and the auxiliary wheel 8.

Working principle of the present invention: After the operator removes the positioning bolt 10, the adjustment plate 11 can be rotated at an angle inside the support rod 6, and the adjustment plate 11 is rotated upward. The operator pushes the cable drum 13 toward the position of the storage groove 9. At this time, the vertically arranged adjustment plate 11 will not affect the pushing of the cable drum 13 toward the support rod 6;

As shown in FIGS. 3, 6 and 7, an adjustment spring 26 is provided at the lower front side of the stabilizing frame 25, the upper end of the adjustment spring 26 is fixedly connected to the stabilizing frame 25, and the lower end of the adjustment spring 26 is fixedly connected to the spring positioning plate 18. When the cable drum 13 passes through the position of the adjustment frame 7 and contacts the auxiliary wheel 8, the front side of the auxiliary wheel 8 will be pressed downward, and the auxiliary wheel 8 moves downward as a whole, and the adjustment spring 26 is compressed.

After the cable drum 13 passes the auxiliary wheel 8, the spring 26 is adjusted to restore the auxiliary wheel 8 to its original height, and then the cable drum 13 moves to the position of the limiting wheel 5. Since the limiting member 701 is arranged at the position of the limiting wheel 5 on the inner side of the stabilizing frame 25, when the cable drum 13 contacts the limiting wheel 5, the limiting wheel 5 is forced downward, and the limiting member 701 contacts the adjusting frame 7 to limit the height of the limiting wheel 5. At this time, the cable drum 13 finally stops between the limiting wheel 5 and the auxiliary wheel 8.

When the support rod 6 stops between the limiting wheel 5 and the auxiliary wheel 8, the electric push rod 24 is pulled backward, and an arc groove 19 is opened in the middle of the adjusting member 23, and an adjusting rod 17 is arranged in the middle of the adjusting member 23, and both ends of the adjusting rod 17 are arranged in the lifting groove 16. When the electric push rod 24 drives the adjusting member 23 to be pulled backward, the adjusting rod 17 can only move along the arc groove 19. Since both sides of the adjusting rod 17 are arranged in the vertical lifting groove 16, the adjusting rod 17 will be vertically upward. The support member 15 is vertically in contact with the middle of the auxiliary wheel 8, so as to fix the auxiliary wheel 8, and the limit wheel 5 and the auxiliary wheel 8 are rotatably arranged in the stabilizing frame 25, so that the cable drum 13 and the internal cables can be fixed without affecting the rotation of the cable drum 13. When the cable needs to be retracted or released, the drive motor 2 is started, and the drive motor 2 can synchronously drive the cable drum 13 to rotate through the auxiliary rotating wheel 14, so that the cable retracting or releasing operation can be performed without separating the internal cables and the cable drum 13 and configuring them separately;

Afterwards, the adjustment plate 11 can be rotated toward the front side of the support rod 6, and the adjustment plate 11 can be fixed by using a bolt to pass through the adjustment threaded hole 1101 on the side of the adjustment plate 11, and the cable head can be pulled out and passed through the square groove opened in the middle of the sliding member 12. When the driving motor 2 is used to retract and release the cable, the auxiliary motor 1202 drives the active roller 1201 to rotate, which can apply an auxiliary friction force to the outer wall of the cable, so that the cable reel 13 and the cable can be retracted and released at the same time, avoiding the traditional method of retracting and releasing the cable separately and causing damage to the cable.

The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
