The first connecting hole 101b is arranged on the cable hook 101 near the side of the threaded head 101a. The screw and nut pair 102c hinges the limit assembly 102 with the cable hook 101 through the first connecting hole 101b. The first elastic member 101c is fixedly arranged on the cable hook 101. The limit block 104 allows the limit assembly 102 to rotate only in one direction on the cable hook 101. One end of the first elastic member 101c is fixedly arranged on the cable hook 101, and the other end of the first elastic member 101c squeezes the limit assembly 102. The first elastic member 101c is arranged on one side of the first connecting hole 101b.

[0035] Preferably, the limiting assembly 102 includes a limiting head 102a, an extrusion assembly 102b and a screw-nut pair 102c, the extrusion assembly 102b is fixedly arranged on the bottom side of the limiting head 102a, the extrusion assembly 102b squeezes the cable arranged on the cable pulley 103, so that the cable is squeezed and limited, the screw-nut pair 102c is 1 screw and 2 nuts, the lower end of the screw is threaded and the upper end is smooth, the two nuts are tightened on the threaded part of the screw, so that the screw-nut pair 102c is limited and the cable hook 101 and the limiting assembly 102 are hingedly connected.

[0036] Furthermore, the limiting head 102a includes a U-shaped groove 102a-1, a second connecting hole 102a-2, an elastic member limiting hole 102a-3 and an arc-shaped opening 102a-4. The cable hook 101 is a U-shaped cylinder. The U-shaped groove 102a-1 is arranged at one end of the limiting head 102a. The U-shaped groove 102a-1 enables the limiting head 102a to be adapted when connected to the cable hook 101. The arc-shaped opening 102a-4 is arranged at the other end of the limiting head 102a. 02a-4 makes the limit head 102a better adapt to the cable hook 101, the second connecting hole 102a-2 is set on one side of the U-shaped groove 102a-1, the screw and nut pair 102c passes through the first connecting hole 101b and the second connecting hole 102a-2, and the elastic member limit hole 102a-3 is set on the limit head 102a. When the first elastic member 101c squeezes the limit assembly 102, one end of the first elastic member 101c falls into the elastic member limit hole 102a-3.

[0037] Furthermore, the U-shaped groove 102a - 1 includes an inner groove 102a - 11 , which is disposed in the U-shaped groove 102a - 1 , and the limit block 104 slides in the inner groove 102a - 11 .

The through holes 104b are arranged on both sides of the U-shaped opening 104a, so that the operator can more conveniently take out the limit block 104.

[0040] Furthermore, the U-shaped opening 104a includes an inclined arc surface 104a-1, which is arranged on the U-shaped opening 104a. The inclined arc surface 104a-1 makes the lower end of the limit block 104 an inclined curved surface. The inclined arc surface 104a-1 enables the limit block 104 to rotate clockwise after being inserted into the U-shaped groove 102a-1. When the limit component 102 rotates counterclockwise, it contacts the U-shaped opening 104a and is limited.

[0041] When in use, the cable hook 101 and the limit head 102a are respectively provided with a first connecting hole 101b and a second connecting hole 102a-2, and the cable hook 101 and the limit assembly 102 are hingedly connected by a screw nut pair 102c. When the limit block 104 is inserted into the U-shaped groove 102a-1, the limit head 102a can only rotate clockwise due to the inclined arc surface 104a-1, and the C-shaped pressure head 102b-2 squeezes the cable set on the cable pulley 103, and the second elastic member 102b-1 is subjected to the reverse force generated by the C-shaped pressure head 102b-2. At this time, the second elastic member 102b-1 is in a compressed state, and the first elastic member 102b-1 is in a compressed state. When the elastic member 101c squeezes the limit head 102a, one end of the first elastic member 101c falls into the limit hole 102a-3 of the elastic member. At this time, the first elastic member 101c is also in a compressed state, causing the limit head 102a to generate a counterclockwise force, and the limit block 104 can only rotate clockwise. Therefore, when the cable is set on the cable pulley 103, the cable is fixed and limited, and the cable hook 101 and the cable are in direct contact to avoid possible wear on the cable when pulling. When it needs to be removed, only the screw and nut pair 102c needs to be removed, and the limit block 104 can be taken out from the U-shaped groove 102a-1. This structure is convenient for operators to operate quickly.
