[0036] Reference Figure 2 - Figure 4The snap-fit ​​assembly 300 includes a support plate 317, which is the main frame of the snap-fit ​​assembly 300. It is horizontally positioned at the bottom of the tailplate device 2, providing an installation platform for other components. This is possible when the support plate 317 is level with the ground. A slider 311 is slidably connected to the left section of the inner wall at the bottom of the support plate 317. The slider 311 can slide horizontally along the left section of the inner wall at the bottom of the support plate 317. A fixing post 312 is fixedly connected to the front surface of the slider 311, connecting a tension spring 313 and a limiting rod 314, transmitting the movement of the slider 311 to the limiting rod 314. The front surface of the fixing post 312 is elastically connected to the limiting rod 314 via the tension spring 313. The tension spring 313 is always in a stretched state, applying force to the limiting rod 314. A backward pulling force is applied to keep the limiting rod 314 in the insertion state with the slot 319 in its natural state. A push rod 315 is hinged to the right end of the front surface of the slider 311. A guide plate 316 is hinged to the end of the push rod 315 away from the slider 311. There are two sets of guide plates 316, located on the front and rear sides of the inner wall of the bottom end of the support plate 317, respectively. They can slide along the inner wall of the support plate 317 and are used to install the locking block 321 and drive its movement. The front surface of the guide plate 316 is elastically connected to the inner wall of the front side of the support plate 317 through a compression spring 320. The compression spring 320 applies a backward pushing force to the guide plate 316 in its natural state, so that the guide plate 316 maintains its initial position when no external force is applied. The inner wall of the front side of the guide plate 316 is elastically connected through a limiting spring 322. A locking block 321 is attached, which protrudes outward under the elastic force of the limiting spring 322. A guide groove 318 is formed on the front surface of the support plate 317, which provides a path for the sliding of the limiting rod 314. Its length and width match the limiting rod 314 to ensure that the limiting rod 314 moves along a fixed trajectory. A locking groove 319 is formed on the front surface of the support plate 317. The locking groove 319 is annular and communicates with the guide groove 318. When the limiting rod 314 is inserted into the locking groove 319, it can restrict the movement of the slider 311, thereby fixing the position of the guide plate 316 and the locking block 321. The guide plate 316 is slidably connected to the inner wall of the bottom end of the support plate 317, ensuring that the guide plate 316 can only slide back and forth along the inner wall of the support plate 317 to avoid displacement. The limiting rod 314 is slidably connected to the outer wall of the fixed column 312. The limiting rod 314 can slide back and forth along the outer wall of the fixed column 312. The annular recess on its rear surface cooperates with the locking block 321. The rear surface of the limiting rod 314 has an annular recess. The guide groove 318 is connected to the locking groove 319, so that the limiting rod 314 can slide from the guide groove 318 into the locking groove 319 to realize the switching of the limiting state. The locking groove 319 is annular. The rear surface of the locking block 321 is set as an inclined surface that gradually slopes downward from back to front, so that the locking block 321 retracts inward. The limiting rod 314 is inserted into the inner wall of the locking groove 319. The movement of the slider 311 is restricted by the insertion and cooperation, thereby fixing the guide plate 316 and the locking block 321. The limiting rod 314 slides on the inner wall of the guide groove 318.Furthermore, the outer wall of the limiting rod 314 contacts the upper and lower ends of the inner wall of the guide groove 318, ensuring the stability of the limiting rod 314 when sliding within the guide groove 318 and preventing wobbling.

[0037] Reference Figure 3 , Figure 5 The lifting assembly 4 includes a trolley 41, which is the main body of the lifting assembly 4 and is used to carry tools. Its top end can be inserted into the inner surface of the support plate 317. The top ends of the front and rear sides of the trolley 41 are provided with protrusions to achieve connection with the snap-fit ​​assembly 300. A push plate 42 is slidably connected inside the trolley 41. The push plate 42 can slide up and down vertically inside the trolley 41 to place tools and drive the tools to lift and lower. A slide groove 43 is opened in the lower right section of the push plate 42. The slide groove 43 provides space for the sliding of the rotating shaft 49, so that the rotating shaft 49 can move in the slide groove 43 with the movement of the lifting rod 44. The rotating shaft 49 is slidably connected to the inner wall of the slide groove 43. The rotating shaft 49 connects the lifting rod 44 and The push plate 42 can slide within the slide groove 43, transmitting the movement of the lifting rod 44 to the push plate 42. The lifting rod 44 is hinged to the front end of the outer wall of the rotating shaft 49. One end of the lifting rod 44 is hinged to the rotating shaft 49, and the other end is hinged to the fixed seat 410, which supports the push plate 42 and enables height adjustment. The end of the lifting rod 44 away from the push plate 42 is hinged to the fixed seat 410, which is fixed to the inner wall of the bottom of the trolley 41, providing a fixed hinge point for the lifting rod 44 and ensuring stable movement of the lifting rod 44. The lower left section of the push plate 42 is hinged to the second lifting rod 45, enabling the lifting and lowering of the push plate 42. The end of the lifting rod 44 away from the push plate 42 is hinged to the movable seat 46, which can... The inner wall at the bottom of the trolley 41 slides horizontally, providing a movable hinge point for the second lifting rod 45. A threaded rod 47 is threadedly connected to the inner surface of the movable seat 46. The threaded rod 47 drives the movable seat 46 to move horizontally via threaded transmission. A turntable 48 is fixedly connected to the right end of the threaded rod 47. Universal wheels 5 are installed on the lower surface of the trolley 41, positioned at the four corners, allowing the trolley 41 to move flexibly across various terrains, facilitating the transport of vehicles in areas inaccessible to other vehicles. The lower surface of the fixed seat 410 is fixedly connected to the inner wall at the bottom of the trolley 41, ensuring the fixed seat 410 is in a fixed position and providing stable support for the first lifting rod 44. The front surface of 4 is hinged to the center of the rear surface of the second lifting rod 45, serving as the fulcrum for the movement of the first lifting rod 44 and the second lifting rod 45. The lifting and lowering of the push plate 42 is achieved by changing the included angle between the two. The turntable 48 is rotatably connected to the right surface of the trolley 41, allowing the operator to rotate the turntable 48 outside the trolley 41 for convenient operation. A handle is rotatably connected to the left surface of the turntable 48 away from the center. The handle can rotate around the turntable 48, making it easy for the operator to hold and rotate, saving effort and making it convenient. The movable seat 46 is slidably connected to the inner wall of the bottom of the trolley 41, ensuring that the movable seat 46 slides stably in the horizontal direction and ensuring that the threaded transmission of the threaded rod 47 can be effectively converted into the linear motion of the movable seat 46.

[0038] Working principle: When in use, align the trolley 41 with the bottom inner wall of the support plate 317 and insert it. After squeezing the locking block 321 on the lower surface of the support plate 317 to release the limit, insert the protrusion on the upper surface of the trolley 41 into the upper part of the locking block 321 to fix the trolley 41. When it is necessary to remove the trolley 41, pull the limiting rod 314 to disengage it from the slot 319 to release the limit, and then slide it along the guide groove 318. During this process, the limiting rod 314 will also stretch the tension spring 313 to generate a reaction force. At the same time, the limiting rod 314 drives the fixing column 312 to move the slider 311 to the left, which drives the push rod 315 to push the two sets of guide plates 316 to expand, so that the locking block 321 separates from the protrusion at the top of the trolley 41, and the trolley 41 can be removed.

[0039] When it is necessary to adjust the height of the push plate 42 inside the trolley 41, turn the handle to drive the threaded rod 47 to rotate synchronously. When the threaded rod 47 rotates, the moving seat 46 moves along its axis, driving the second lifting rod 45 to move. Since the first lifting rod 44 and the second lifting rod 45 are hinged at the middle position, and the other end of the first lifting rod 44 is hinged to the fixed seat 410, the fixed seat 410 is fixed inside the trolley 41. The hinge angle between the first lifting rod 44 and the second lifting rod 45 changes with the movement of the moving seat 46. When the moving seat 46 moves to the left, the first lifting rod 44 slides along the slide groove 43 of the push plate 42, pushing the push plate 42 to rise. When the moving seat 46 moves to the right, the push plate 42 lowers accordingly and retracts into the trolley 41, realizing height adjustment. The universal wheels 5 on the lower surface of the trolley 41 can drive the trolley 41 to move flexibly, ensuring efficient and stable on-site service.
