[0025] Example

[0026] Reference Figure 1-4A towing mechanism of a tractor comprises a mechanism body 1, a trigger button 2 and a slide rail 3. The upper surface of the mechanism body 1 is a smooth metal surface. The inner side of the mechanism body 1 is embedded with the trigger button 2, and the upper end of the mechanism body 1 is fixedly connected with the slide rail 3. The upper surface of the slide rail 3 is embedded with a slider 4. The upper end of the slider 4 is fixedly connected with a protective cover 5. The upper surface of the protective cover 5 is fixedly connected with a pressure plate 6, and the bottom of the pressure plate 6 is fixedly connected with a latch 7. The outer side of the mechanism body 1 is provided with a hook 12, and the hook 12 The surface of the trigger button 2 is provided with a connecting hole, and the inner side of the hook 12 is fixedly connected with a trigger rod 13, the inner side of the protective cover 5 is connected with a first spring 15, the inner side of the trigger button 2 is fixedly connected with a connecting rod 17, and the outer side of the connecting rod 17 is connected with a rotating shaft 18, the upper end of the rotating shaft 18 is provided with a card plate 19, the upper end of the card plate 19 is provided with a connecting plate 20, and the connecting plate 20 is fixedly connected to the slider 4, and one side of the slider 4 is fixedly connected with a pulling spring 14, the mechanism body 1 is an inverted concave shape as a whole, and the mechanism body 1 The upper and lower surfaces of the two plates are penetrated with latch holes 11. When the staff uses the device, the staff can insert the hook 12 on the side of the towed mechanism into the inner side of the mechanism body 1, so that the trigger rod 13 on the side of the hook 12 squeezes the trigger button 2. The trigger button 2 is squeezed and drives the shaft 18 to rotate through the connecting rod 17. After the shaft 18 rotates, the connecting plate 20 at the upper end of the shaft 18 is separated from the surface of the shaft 18, thereby causing the slider 4 to lose its limit. After the slider 4 loses its limit, the spring 14 is pulled to pull the slider 4. When the slider 4 moves to the upper end of the latch hole 11, the bottom of the latch 7 breaks away from the upper surface of the mechanism body 1 and enters the latch hole 11, causing the bottom of the latch 7 to lose support. After the latch 7 loses support, the pressure plate 6 retracts downward under the action of the first spring 15, driving the latch 7 to pass through the connecting hole on the surface of the latch hole 11 and the hook 12, so that the device can automatically insert the latch 7 into the connecting hole on the surface of the latch hole 11 and the hook 12.

[0027] One end of the pull spring 14 is fixedly connected to the limit plate 9, and the inner side of the upper end of the limit plate 9 is embedded with a lock hole 10, and one side of the lock hole 10 is embedded with a reset mechanism 16. The reset mechanism 16 is composed of a pull rod, a connecting rod and a spring rod, and the pull rod is embedded and connected to the outer side of the limit plate 9. The lock head 8 and the outer side of the lock body inside the lock hole 10 are both arc surfaces, and the arc surfaces of the lock head 8 and the lock body are symmetrically arranged. When the first spring 15 drives the pressure plate 6 and the latch 7 to press down, the lock on the bottom side of the pressure plate 6 The head 8 can be inserted into the lock hole 10. When the lock head 8 is inserted into the lock hole 10, the lock head 8 can push the lock body into the inner side of the lock hole 10 through the curved surface of the surface through the inertia of downward pressure and the pulling force provided by the first spring 15. Then the lock head 8 enters the bottom of the lock body. At this time, under the action of the spring rod, the lock body is reset and stuck on the upper surface of the lock head 8 to limit the lock head 8, so that the device can enhance the stability of the bolt 7 after it is inserted into the lock hole 10 during the process of automatically completing the bolt.

[0028] The rotating shaft 18 as a whole is composed of a card rod body and two rotating shafts, and the two rotating shafts are respectively located at the center of the rotating shaft 18 and the connection between the rotating shaft 18 and the connecting rod 17. Second rotating shafts are provided on both sides of the card plate 19. One side of the second rotating shaft is embedded and connected to the inner wall of the mechanism body 1, and the other side of the second rotating shaft is fixedly connected to the card plate 19. When the connecting rod 17 moves inward, the connecting rod 17 will drive the rotating shaft 18 to move through the rotating shaft between the rotating shaft 18 and the connecting rod 17. At this time, due to the fulcrum formed by the rotating shaft at the center of the rotating shaft 18, the rotating shaft 18 will not translate with the connecting rod 17, but will be offset through the rotating shaft at the center, so that the rotating shaft 18 is tilted to one side and separated from the side of the card plate 19. After the card plate 19 loses the limit of the rotating shaft 18, it will rotate through the second rotating shaft under the pulling force of the pulling spring 14 to separate from the bottom of the connecting plate 20.

[0029] The lock hole 10 as a whole is composed of a rectangular groove and a lock body, and the lock body is connected to the connecting rod and the spring rod of the reset mechanism 16. When the staff needs to take the lock head 8 out from the inside of the lock hole 10, the staff can pull the pull rod to make the pull rod drive the lock body to move to one side of the reset mechanism 16 through the connecting rod, thereby making the lock body detach from the upper surface of the lock head 8. At this time, the staff can take out the lock head 8. After the staff releases the pull rod, the pull rod will drive the lock body to reset under the action of the spring rod.

[0030] Working principle: when the staff uses this device, the staff can insert the hook 12 on the side of the towed mechanism into the inner side of the mechanism body 1, so that the trigger rod 13 on the side of the hook 12 squeezes the trigger button 2. The trigger button 2 is squeezed and drives the rotating shaft 18 to rotate through the connecting rod 17. After the rotating shaft 18 rotates, the connecting plate 20 at the upper end of the rotating shaft 18 is separated from the surface of the rotating shaft 18, thereby causing the slider 4 to lose its limit. After the slider 4 loses its limit, under the action of the pulling spring 14, the pulling spring 14 will pull the slider 4 to one side of the latch port 11. When the slider 4 moves to the upper end of the latch port 11, the bottom of the latch pin 7 is separated from the upper surface of the mechanism body 1 and enters the latch port 11, causing the bottom of the latch pin 7 to lose support. After the latch pin 7 loses support, the pressure plate 6 retracts downward under the action of the first spring 15, driving the latch pin 7 to pass through the connecting hole on the surface of the latch port 11 and the hook 12, so that the device can automatically insert the latch pin 7 into the connecting hole on the surface of the latch port 11 and the hook 12.

[0031] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

[0032] In the description of the present invention, it is necessary to understand that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
