[0030] according to Figure 2 , Figure 5 and Figure 7 As shown, a rotating table 104 is installed at the central end of the cross slide table 102, and four groups of rigid arc rods 105 are rotatably connected to the circumference of the rotating table 104. The side ends of the rigid arc rods 105 are tightly connected to the side surfaces of the sliding buffer blocking rods 106, and then the rigid arc rods 105 transmit the force of the sliding buffer blocking rods 106 to the rotating table 104. The rotating table 104 further disperses the impact force by rotating. The rotating table 104 will rotate when it is subjected to impact force, and disperse the impact force to the rigid arc rods 105 in four directions through its rotational motion. The arc-shaped design of the rigid arc rods 105 allows the force to be transmitted along its arc-shaped trajectory to further disperse the impact force.

[0032] according to Figure 2 and Figure 5As shown, the rope adjustment assembly 9 includes a top connecting plate 91 and a bottom connecting plate 93, and the top connecting plate 91 and the bottom connecting plate 93 are connected by a central column 103. The first adjusting tooth ring 92 and the second adjusting tooth ring 94 are rotatably connected on the surface of the top connecting plate 91 and the bottom connecting plate 93 respectively. When it is necessary to adjust the length of the traction rope 5, the user can rotate the first adjusting tooth ring 92 through the operation mode of the explosion-proof impact assembly 8, so that the other second adjusting tooth ring 94 rotates accordingly, thereby changing the length of the traction rope 5, and the first adjusting tooth ring 92 and the second adjusting tooth ring 94 are respectively rotatably connected on the surface of the top connecting plate 91 and the bottom connecting plate 93, and the relative position is kept unchanged by the central column 103, so that the first adjusting tooth ring 92 and the second adjusting tooth ring 94 can rotate freely between the top connecting plate 91 and the bottom connecting plate 93 while maintaining the tension of the traction rope 5.

[0033] according to Figure 1 , Figure 2 and Figure 5 As shown, the locking structure assembly 7 includes a pressing piece 71, a force-bearing hinge seat 72 is installed on the side end of the pressing piece 71, a pressure rod 73 is hinged inside the force-bearing hinge seat 72, the other side end of the pressing piece 71 is rotatably connected to a connecting rod through a ball joint, and a limiting rotating piece 75 is fastened to the side end of the connecting rod. When the pressing piece 71 is not pressed, the pressure rod 73 is in an initial position, and there is no pressure between the friction pressure plate 74 and the limiting rotating piece 75. At this time, the first adjusting tooth ring 92 and the second adjusting tooth ring 94 can rotate freely to adjust the length of the traction rope 5.

[0034] according to Figure 1 , Figure 2 and Figure 5 As shown, a friction pressure plate 74 is installed on the side end of the pressure rod 73, and the limiting rotating member 75 and the friction pressure plate 74 are both located inside the shell 1 to form a rotational connection. When the user presses the pressing member 71, the pressure rod 73 swings through the force-bearing hinge seat 72, and the swing of the pressure rod 73 drives the friction pressure plate 74 to press the limiting rotating member 75.

[0035] according to Figure 1 , Figure 2 and Figure 5 As shown, the top and bottom surfaces of the side ends of the limiting rotating member 75 are both provided with toothed edges 76, and the toothed edges 76 and the first adjusting tooth ring 92 and the second adjusting tooth ring 94 form a meshing connection, so that after the friction pressure plate member 74 presses the limiting rotating member 75, the toothed edges 76 of the limiting rotating member 75 mesh with the first adjusting tooth ring 92 and the second adjusting tooth ring 94 to prevent their rotation.

[0036] according to Figure 1 and Figure 2As shown, the outer part of the reinforced rope end 86 is wrapped with a traction rope 5, and the side surface of the shell 1 is provided with an inlet and outlet rope end. The traction rope 5 passes through the inlet and outlet rope end and is connected to a connecting lock 4. The traction rope 5 enters and exits the shell 1 through the inlet and outlet rope end, and is connected to a pet collar or a harness through the connecting lock 4.

[0037] according to Figure 1 and Figure 2 As shown, a gripping end is arranged at the side end of the shell 1, and a control button 6 is installed on the surface of the gripping end. The control button 6 and the driving motor 3 form an electromagnetic signal connection. When the user presses the control button 6, the electromagnetic signal is sent to the driving motor 3, so that the driving motor 3 drives the worm 11 to rotate according to the signal control, that is, in the locking mode, the driving motor 3 stops the retraction and release of the traction rope 5, and dynamically ensures the length limit of the traction rope 5 during impact. In the unlocking mode, the driving motor 3 allows the traction rope 5 to be freely extended and retracted according to the activities of the pet.

[0038] The wiring diagram of the drive motor 3 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the drive motor 3 are no longer explained in detail.

[0039] The method of use and working principle of the device are as follows: first, the traction rope 5 is passed through the inlet and outlet rope ends to enter and exit the housing 1, and is connected to the pet collar or harness through the connecting lock 4; then, when the pressing member 71 is not pressed, the pressing rod 73 is in the initial position, and there is no pressure between the friction pressure plate 74 and the limiting rotating member 75; at this time, the first adjusting tooth ring 92 and the second adjusting tooth ring 94 can rotate freely to adjust the length of the traction rope 5, that is, when the user presses the pressing member 71, the pressing rod 73 swings through the force-bearing hinge seat 72, and the swing of the pressing rod 73 drives the friction pressure plate 74 to press the limiting rotating member 75, so that after the friction pressure plate 74 presses the limiting rotating member 75, the toothed edge 76 of the limiting rotating member 75 is aligned with the first adjusting tooth ring 92 and the second adjusting tooth ring 94. The first and second adjusting gear rings 92 and 94 are respectively rotatably connected to the surfaces of the top connecting disk 91 and the bottom connecting disk 93, and the relative positions are kept unchanged by the central column 103, so that the first and second adjusting gear rings 92 and 94 can rotate freely between the top connecting disk 91 and the bottom connecting disk 93, while maintaining the tension of the traction rope 5. When the user presses the control button 6, an electromagnetic signal is sent to the drive motor 3, so that the drive motor 3 rotates according to the signal. The signal control drives the worm 11 to rotate, that is, in the locking mode, the driving motor 3 stops the retraction and release of the traction rope 5, and dynamically ensures that the length limit of the traction rope 5 during impact. In the unlocking mode, the driving motor 3 allows the traction rope 5 to freely retract and retract according to the activities of the pet. When the worm 11 rotates, it drives the worm wheel 12 to rotate synchronously so that when the traction rope 5 is retracted and released, the entire traction rope 5 is in a normal traction operation. When subjected to a sudden impact force, the dovetail slider 85 will slide in the sliding dovetail groove 82 to absorb the impact force by sliding, and the top of the dovetail slider 85 is located in the spiral groove of the spiral groove plane plate 83 and slides, and the impact force is further dispersed by the structure of the spiral groove. The spiral groove plane plate 83 is reinforced by its inner wall surface on the reinforcing connector 81. The top of the sliding buffer blocking rod 106 slides in the sliding dovetail groove 82, so that it can limit the sliding distance of the dovetail slider 85, that is, when the dovetail slider 85 suddenly reaches the trigger position, the sliding buffer blocking rod 106 slides in the cross slide groove platform 102, and the impact force is dispersed in multiple directions, reducing the impact force strength in a single direction.The design of the sliding dovetail groove 82 and the dovetail slider 85 allows the sliding buffer blocking rod 106 to not only slide along the cross-slide platform 102, but also slide on the side of the dovetail slider 85, further increasing the freedom of sliding, thereby better absorbing and dispersing the impact force, reducing the impact feeling of the pet traction device when it is suddenly pulled, and protecting the safety of the pet and the user. Then the rigid arc rod 105 transmits the force of the sliding buffer blocking rod 106 to the rotating table 104, and the rotating table 104 further disperses the impact force by rotating. When the rotating table 104 is subjected to the impact force, it will rotate, and the rigid arc rod 105 disperses the impact force in four directions through its rotational movement. The arc design of the rigid arc rod 105 allows the force to be transmitted along its arc trajectory, further dispersing the impact force. The central column 103 serves as the central support of the rotating table 104 to ensure the stable rotation of the rotating table 104, so that the central column 103 is connected to the connecting shaft 84 through its top to receive the force transmitted by the explosion-proof impact assembly 8.
