Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: comprises a mounting plate 1; the fixed rod 3 is fixedly welded on the top surface of the mounting plate 1; the top of the fixed rod 3 is rotatably connected with a pair wheel 4; the surface of the fixed rod 3 is positioned between the mounting plate 1 and the pair wheel 4, the return spring 2 is wound on the surface of the fixed rod, one end of the return spring 2 is fixedly mounted with the pair wheel 4, and the other end of the return spring 2 is fixedly mounted with the mounting plate 1; the clamping mechanism 7 comprises a through hole 71, a first spring 72 and a clamping plate 73, the through hole 71 is formed in the surface of the pair wheel 4 and located on one side of the top of the surface, the first spring 72 is fixedly welded to two sides of the through hole 71, and the clamping plate 73 is fixedly welded to one end, far away from the inner wall of the through hole 71, of the first spring 72; and a groove 6 is formed in the inner part of the pair of wheels 4 and positioned at the top of the through hole 71, and the groove 6 is formed.
The clamping plate 73 is of an arc-shaped structure, and a non-slip pad is bonded to one side of the clamping plate 73, which is far away from the first spring 72, so that the friction force between the clamping plate 73 and the cable is increased.
Wherein, the surface bonding of wheel 4 is connected with rubber pad 5, avoids the problem that the cable surface takes place the damage.
Wherein, the dead lever 3 is located the inside both sides of wheel 4 and all rotates and is connected with the turning ball, the inside sliding connection of turning ball and wheel 4 reduces and rotates and makes frictional force.
