The sides away from each other are circumferentially provided with multiple groups of raised limiting teeth 31, and a limiting distance is formed between the limiting teeth 31 and the limiting teeth 31; the traction rope 2 is composed of a steel core 201 and a leather cover 202, the steel core 201 is formed by spirally winding a plurality of steel wires, the leather cover 202 is wrapped outside the steel core 201, one end of the traction rope 2 is connected to the inner side of the placement groove 304, the traction rope 2 is wound on the winding shaft 34, and the free end of the traction rope 2 extends outward from the traction port 11, and the opening of the placement groove 304 and the end surface of the second chuck 300 away from the first chuck 30 are provided with a fixing groove 340 with an opening facing outward;

The control button 12 drives the transition control member 13 to drive the limiting member 14 to transition the distance between the limiting intervals, thereby controlling the rotation states of the first chuck 303 and the second chuck 3003 .

It should be noted that a steel rope is used instead of the existing traction rope 2 made of cloth. In order to ensure the stability of the fixed connection of the traction rope 2, the structure of the rotational positioning of the chuck 3 in the working inner cavity adopts the existing common limiting positioning method. The first chuck 30 and the second chuck 300 are provided with multiple groups of raised limiting teeth 31 on the side circumferences away from each other, and a limiting distance is formed between the limiting teeth 31 for use with the control button 12.

A T-shaped connector 203 is provided at the front end of the steel core 201, and the T-shaped connector 203 is threadedly connected to a middle piece 204. A universal rod 205 is rotatably provided at the front end of the middle piece 204. A hanging ring 206 is provided on the universal rod 205, and a locking head 207 is provided on the hanging ring 206.

The maximum outer diameter of the T-shaped connector 203 is smaller than the outer diameter of the middle piece 204.

It should be noted that the rotating universal rod 205 can prevent the pet from driving the lock head 207 to cause the traction rope 2 to rotate or the middle piece 204 and the T-shaped connector 203 to loosen during the movement.

The leather case 202 is divided into two sections and respectively sleeved on the outside of the steel core 201. The leather case 202 is provided with a wear-resistant layer 211, an intermediate layer 212, and an anti-bite layer 213 from the inside to the outside.

In the specific implementation of the present invention, the fixed end of the traction rope is placed outside the fixing groove and connected with a fixing block to cooperate with the inner side of the fixing groove to fix it; or the fixed end of the traction rope is made into a protruding block, which is directly cooperated with the inner side of the fixing groove to fix it;

One end of the formed reset spring sheet is directly connected to the rotating shaft arranged on the working inner cavity, and is placed around the inner side of the reset cavity, and the other end is arranged on the inner side of the limit opening formed between the limit column and the inner side wall of the reset cavity, so as to ensure that when the traction steel rope is pulled out, the traction chuck starts to rotate, and the reset spring sheet is squeezed at this time. When the traction steel rope is no longer constrained, the traction chuck is no longer constrained, and the reset spring sheet starts to reset, so as to realize the recovery of the traction steel rope;

When the leather cover included on the outside of the traction rope is worn out after long-term use or damaged by the pet's bite, the T-type connector is rotated and separated from the middle piece, the damaged leather cover is removed, and a new leather cover is re-attached to the outside of the steel core from the T-type connector. The steel core with the spirally wound steel wire will not be damaged during the pet's bite.

The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
