[0025] Reference Figure 1-5 As shown, it is a preferred embodiment provided by the utility model.

[0026] The traction device includes a casing 10 and a rope winding wheel 13. An internal cavity 12 is provided in the casing 10. The rope winding wheel 13 is rotatably arranged in the internal cavity 12. A traction rope is wound on the rope winding wheel 13. A rope outlet 11 for the traction rope to extend out is provided on the front end of the casing 10. The casing 10 has an inwardly recessed rope locking groove 40. A locking mechanism 50 for locking the traction rope is provided in the rope locking groove 40. The locking mechanism 50 is slidably matched with the casing 10.

[0027] The traction device provided above pulls the traction rope out of the housing 10, and after the traction rope is looped around an object, the traction rope is stuck in the rope locking groove 40, and the traction rope is fixed and locked by the locking mechanism 50 in the rope locking groove 40, so that the traction rope can cooperate with the locking mechanism 50 to directly and quickly tie the pet to a certain position, thereby solving the problem that the traction rope of the traction device has the problem that the process of tying the pet to a certain position is too cumbersome.

[0028] In this embodiment, the locking mechanism 50 includes a sliding block 51 and a control block 52. The control block 52 is fixed on the outer side of the sliding block 51 and exposed outside the housing 10. The sliding block 51 is located in the lock rope groove 40. One end of the sliding block 51 has a lock column 53 protruding outward, and the lock column 53 is horizontally located in the lock rope groove 40; the other end of the sliding block 51 is connected to a first elastic member 54, and the sliding block 51 is connected to the housing 10 through the first elastic member 54.

[0029] The control block 52 can be used to control the sliding block 51 to slide in the rope locking groove 40. The sliding block 51 uses the first elastic member 54 to automatically drive the sliding block 51 to drive the locking column 53 to be stuck in the rope locking groove 40. If the traction rope needs to be stuck in the rope locking groove 40, it is only necessary to slide the outer side of the sliding block 51 and put the traction rope part into the rope locking groove 40. Then, the sliding block 51 is controlled to drive the locking column 53 to stick the traction rope part in the rope locking groove 40.

[0030] In this embodiment, the rope locking groove 40 has an outer opening, and an isolation strip 41 is provided on the outer opening. The isolation strip 41 separates the outer opening into a rope entrance and a limit opening, and the control block 52 is located on the limit opening. In this way, the rope locking groove 40 is separated by the isolation strip 41, and the control block 52 will not affect the placement of the traction rope into the rope entrance, and the isolation strip 41 will limit the control block 52 from entering the rope entrance.

[0031] In this embodiment, the housing 10 has a handle portion 20 for holding, and a switch button 30 is provided on the handle portion 20. The switch button 30 is located at the holding position of the handle portion 20, and the switch button 30 is used to lock the rotation of the rope reel 13 through the braking mechanism 60.

[0032] The handle 20 drives the brake mechanism 60 through the switch button 30 to lock the rotation of the rope winding wheel 13, thereby preventing the traction rope from loosening at will and reinforcing the fixation of the traction rope.

[0033] In this embodiment, a gear plate 14 is disposed on the outer side of the rope winding wheel 13, the gear plate 14 is fixedly connected to the rope winding wheel 13, and the switch button 30 and the gear plate 14 are movably abutted by a brake mechanism 60. In this way, the switch button 30 can limit the rotation of the gear plate 14 through the brake mechanism 60, thereby limiting the rotation of the rope winding wheel 13 through the gear plate 14, thereby preventing the traction rope from continuing to disengage from the rope winding wheel 13.

[0034] In this embodiment, the braking mechanism 60 includes a positioning frame 61 and a lifting lock block 62 for clamping the gear plate 14. The positioning frame 61 is installed on the inner wall of the internal cavity 12. The lifting lock block 62 is inserted into the positioning frame 61 from top to bottom. The lifting lock block 62 is connected to the positioning frame 61 through a second elastic member 63. The switch button 30 movably abuts against the top of the lifting lock block 62.

[0035] The switch button 30 is pressed against the lifting lock block 62, so that the lifting lock block 62 moves downward, and the lifting lock block 62 is engaged with the gear disk 14 to prevent the rope winding wheel 13 from rotating, causing the traction rope to continue to detach from the rope winding wheel 13; after completing the restriction on the rope winding wheel 13, the second elastic member 63 uses its own elastic force to push the lifting lock block 62 upward, so that the lifting lock block 62 returns to its original position.

[0036] In this embodiment, the positioning frame 61 is provided with a limit frame 64 for mounting the lifting lock block 62 on the positioning frame 61. The limit frame 64 is movably connected to the positioning frame 61. The top of the lifting lock block 62 is exposed above the limit frame 64 and movably abuts against one end of the switch button 30. The bottom of the lifting lock block 62 is exposed below the positioning frame 61 and movably abuts against the gear plate 14. In this way, the positioning frame 61 can position and mount the lifting lock block 62 between the positioning frame 61 and the limit frame 64 through the limit frame 64, thereby preventing the lifting lock block 62 from arbitrarily detaching from the positioning frame 61.

[0037] In this embodiment, one end of the switch button 30 has a pressing hook 31 extending toward the lifting lock block 62, the pressing hook 31 abuts against the top of the lifting lock block 62, and a wedging strip 15 for limiting the wedging of the pressing hook 31 is provided on the inner side wall of the internal cavity 12. In this way, the switch button 30 can press the lifting lock block 62 downward through the pressing hook 31, so that the lifting lock block 62 can limit the rotation of the gear plate 14, and the internal cavity 12 can position the pressing hook 31 in the internal cavity 12 through the wedging strip 15, so that the switch button 30 can position the lifting lock block 62 on the gear plate 14 through the pressing hook 31 to prevent the gear plate 14 from rotating at will.

[0038] In this embodiment, a sliding groove 21 is provided on the handle 20 for the switch button 30 to slide, and the sliding groove 21 is connected to the internal cavity 12. The top of the switch button 30 is exposed outside the sliding groove 21, and the bottom of the switch button 30 is located in the internal cavity 12. In this way, the switch button 30 can slide through the sliding groove 21.

[0039] The handle portion 20 is located at the upper portion of the housing 10 , the rope locking groove 40 is located at the bottom of the housing 10 , and the rope outlet 11 is located between the handle portion 20 and the rope locking groove 40 .

[0040] The first elastic member 54 and the second elastic member 63 are both springs.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
