The combined notches enable the guide shaft 201 to move by rotation when it is pushed by the elasticity of the elastic spring 2042. Therefore, a limiting block 2041 is required to limit it.

Define the groove 2012, which is a semi-circular groove with a smaller radius on the other end of the guide shaft 201. At the same time, when the guide shaft 201 rotates, it fits in one end of the push groove 204. The defined groove 2012 will be against the limit block The inclined surface at one end of 2041 forces its limiting block 2041 to shrink, so that its guide shaft 201 loses its rotation limitation, allowing it to rotate to move toward the shrinking shaft 203 .

Or the grooves on the surface will also be separated from each other.

Reset plate 2032, the reset plate 2032 is a disc elastically connected to one side of the groove in the middle of the contraction shaft 203 through the compression spring 2034, and the other side of the reset plate 2032 is attached to one side of the expansion block 2031, and the reset plate 2032 The surrounding surface of the guide shaft 201 is provided with thread-like grooves. When the guide shaft 201 rotates and moves to make the expansion block 2031 shrink, the reset plate 2032 on the side of the middle part of the contraction groove 2033 will also lose its limiting resistance, so that it can be reset. The plate 2032 will push the guide shaft 201 in the opposite direction through the compression spring 2034 on one side, because the compression spring 2034 is more elastic than the elastic spring 2042, so it will also push the elastic spring 2042 to compress.

working principle:

The specific usage and function of this embodiment, firstly, the waist belt is wrapped around the wearing bracket 101, and then the main body 1 is conveniently carried on the body by wearing the belt on the construction personnel, and then the cables that need to be laid are simply The winding on the guide shaft 201 is brought to the electric tower or pole that needs to be wired, and when the construction personnel climbs on the electric tower or pole that needs to be wired, they can pull the wire wound on the guide shaft 201 The cable is used to extend the cable, and when the cable is pulled to extend from the guide shaft 201, the friction will drive the guide shaft 201 to rotate, and when the guide shaft 201 rotates, the power generated by the rotation can be more convenient. The cable is pulled, and when the guide shaft 201 rotates, the limiting groove 2012 at one end of the pushing groove 204 will be against the slope at one end of the limiting block 2041, forcing the limiting block 2041 to shrink, so that the guiding shaft 201 will lose its The limitation of rotation allows it to rotate and move into the retractable shaft 203 by rotating, and at the same time, the elastic spring 2042 that pushes the connection between the groove 204 and the guide shaft 201 will also be extended to push the guide shaft 201 to one side through elasticity Rotate and move, so that the guide shaft 201 can rotate by itself through the elasticity of the elastic spring 2042 to wind and guide the cable to the main body 1, making it easier for construction personnel to pull the cable for laying, and at the same time the guide shaft 201 rotates because its other end is fitted in the contraction shaft 203, and when the guide shaft 201 rotates, the extrusion groove 2011 will be against the rotation chute 20311 of the expansion block 2031 on the inner wall of the contraction shaft 203, through The slots where the two are fitted together enable the guide shaft 201 to move by rotation when it is pushed by the elasticity of the elastic spring 2042, so a limiting block 2041 is required to limit it, and when the guide shaft 201 rotates toward the contraction groove 2033 When rotating and moving in the center, the expansion block 2031 will be forced to shrink into the shrinking groove 2033 to expand its diameter so that the guide shaft 201 can pass through because the inclined plane movement of the pressing groove 2011 and the rotating chute 20311 are opposed, and at the same time the surface of the two The groove marks will also be separated from each other, and the expansion block 2031 is expanded by the extension of its extension rod 20312 when it is extended by extrusion, and finally when the guide shaft 201 rotates and moves to make the expansion block 2031 contract, its contraction groove 2033 The return plate 2032 on one side of the middle part of the groove will also lose its limiting resistance, so that the return plate 2032 will push the guide shaft 201 in the opposite direction through the compression spring 2034 on one side, because the elastic ratio of the compression spring 2034 The larger elastic spring 2042 will also push the elastic spring 2042 to be compressed. At the same time, because the contraction of the expansion block 2031 and the separation of the extrusion groove 2011 make it impossible to rotate when the guide shaft 201 is reset, then its limiting block 2041 is re-embedded. fit into the limiting groove 2012 to limit the guide shaft 201, so that it is more labor-saving when pulling the cable Make the layout of its power grid more efficient and convenient, and then when the guide shaft 201 is reset, the expansion block 2031 will shrink and reset due to the elasticity of the extension rod 20312, and the reset plate 2032 will also be due to the inertia generated by the compression spring 2034 after popping out And carry out certain movement backward, and reset plate 2032 peripheral edge is provided with the ring that fits with the notch on the surface of expansion block 2031, and through the contraction of both, force reset plate 2032 to reset through the notch ring at noon. The reset plate 2032 is defined on one side of the expansion block 2031 to offset.
