Example III

As shown in fig. 6, 8, 9, 11 and 12, the present embodiment further improves the present application based on the first embodiment and the second embodiment, a spiral groove 10011 is formed on the inner circumference side of a connecting sleeve 7031, a guide block 10012 located in the spiral groove 10011 is configured on an output rod 7032, a transmission assembly 10 comprises a mounting sleeve 1001 mounted on a bearing frame 1, a wedge plate 1002 is vertically and slidably mounted in the mounting sleeve 1001, a connecting spring 1003 is mounted between the wedge plate 1002 and the mounting sleeve 1001, a driving cylinder 1004 is rotatably inserted between two ends of the mounting sleeve 1001 through a one-way bearing, A hollow plate 1005 used for being in inclined surface contact with the wedge plate 1002 is arranged on the outer peripheral side of the driving cylinder 1004, a wedge groove 1006 is arranged on the outer peripheral side of the connecting sleeve 7031, a wedge block 1007 used for being inserted in the wedge groove 1006 is arranged in the hollow plate 1005 in a sliding manner, a reset spring 10010 is arranged between the wedge block 1007 and the hollow plate 1005,

the mounting sleeve 1001 are rotatably mounted through a one-way bearing, the driving cylinder 1004 can only rotate clockwise and cannot rotate anticlockwise, and when the connecting sleeve 7031 rotates anticlockwise, the inclined surface of the wedge groove 1006 formed on the connecting sleeve 7031 contacts with the inclined surface of the wedge block 1007, because the driving cylinder 1004 can only rotate clockwise and cannot rotate anticlockwise, so the rotation of the coupling sleeve 7031 counterclockwise forces the wedge 1007 to move upward, and when the output rod 7032 is reversed (rotated clockwise as shown in fig. 6), firstly, with the output rod 7032 reversed, the wedge shaped groove 1006 is blocked by the wedge 1007 to indirectly drive the driving cylinder 1004 to rotate clockwise until the hollow plate 1005 mounted on the driving cylinder 1004 abuts against the inclined surface of the wedge shaped plate 1002, the driving cylinder 1004 stops moving, at this time, the output rod 7032 continues to rotate clockwise, at this time, because the rotation of the coupling sleeve 7031 clockwise causes the wedge shaped groove 1006 to contact with the wedge shaped groove 1007, So the connecting sleeve 7031 can only move along the length direction of the wedge-shaped groove 1006, the output rod 7032 rotates clockwise to force the guide block 10012 to move in the spiral groove 10011, so that the connecting sleeve 7031 is forced to move away from the grinding drum 2, the homing spring 1009 is compressed until the guide block 10012 moves to the other end of the spiral groove 10011, the output rod 7032 continuously rotates clockwise and is in hard contact with the connecting sleeve 7031, so that the hollow plate 1005 can push the wedge-shaped plate 1002 to move upwards, so that the driving drum 1004 can rotate clockwise, when the hollow plate 1005 is separated from the inclined surface of the wedge plate 1002 and continues to rotate, the centrifugal force generated by the rotation of the output rod 7032 increases the contact force between the wedge 1007 and the plane of the wedge groove 1006, so that the return spring 1009 is not easy to return to the compressed state even if the output rod 7032 rotates clockwise, so that the connecting sleeve 7031 slides, when the output rod 7032 rotates reversely (as shown in fig. 6 rotates clockwise), the polishing tool 702 mounted on the rotating disc 701 moves away from the polishing cylinder 2, so that no additional driving force is required to control the rotating disc 701 to move horizontally, The operation is more convenient, the operation is simple, the motor is only required to be controlled to rotate positively and negatively, when the output rod 7032 in reverse rotation starts to rotate positively, the homing spring 1009 provides elastic driving force to the connecting sleeve 7031 in the direction close to the grinding cylinder 2, so that one end of the spiral groove 10011 of the guide block 10012 moves to the other end, in the process, even if the wedge-shaped block 1007 is inserted into the wedge-shaped groove 1006, the movement of the homing spring 1009 is not reset, because the inclined surface of the wedge-shaped block 1007 contacts with the inclined surface of the wedge-shaped groove 1006, the connecting sleeve 7031 rotates normally to reset, Specifically, the elastic force of the abutting spring piece is larger than the elastic force of the return spring 1009, and the elastic force of the return spring 1009 is larger than the elastic force of the return spring 10010.

Example IV
