[0035] According to an optional embodiment of the present invention, the gripping portion 351 includes more than two raised strips, and the raised strips can clamp the edge of the cargo container of the truck, thereby improving the grip between the second supporting plate 35 and the truck.

[0036] According to an optional embodiment of the present invention, the gripping portion 351 includes two or more silicone strips. The silicone strips can increase the friction between the second supporting plate 35 and the truck, thereby improving the grip between the second supporting plate 35 and the truck.

[0037] According to an optional embodiment of the present invention, the bottom wall of the device body 1 is rotatably connected to a swivel seat 36 .

[0038] Implementation process: When the user needs to transfer hazardous chemicals to a truck, the user places the hazardous chemicals on the lifting plate 30, and the user turns the handle 8 to drive the first transmission disc 7 to rotate. Since the diameter of the first transmission disc 7 is smaller than the diameter of the second transmission disc 11, the user can drive the second transmission disc 11 to rotate through the transmission chain 10 with less effort when the first transmission disc 7 is turned. When the second transmission disc 11 rotates, it will drive the movable rod 14 to slide back and forth in the cylinder 17. At the same time, under the limit of the second universal joint 16, the movable rod 14 and the cylinder 17 will tilt back and forth, so that the front end of the movable rod 14 moves back and forth up and down. When the front end of the movable rod 14 moves upward, it pushes the transmission block 18 upward, The distance between the cylinder 17 and the front end of the movable rod 14 (resistance arm) is smaller than the distance between the cylinder 17 and the rear end of the movable rod 14 (power arm), that is, the resistance arm is smaller than the power arm. According to the lever principle formula: power × power arm = resistance × resistance arm, a smaller power can push a larger resistance, that is, the transmission block 18 can be pushed upward with less effort, and the first meshing tooth 20 on the transmission block 18 will drive the ratchet gear 26 to rotate, and the ratchet gear 26 drives the second meshing tooth 24 to overcome the elastic force of the second elastic member 25 to rotate, and the ratchet gear 26 drives the spur gear 27 to rotate, and the spur gear 27 drives the spur rack 28 to move upward, so that the lifting plate 30 and the dangerous chemicals move upward;

[0039] When the front end of the movable rod 14 moves downward, the transmission block 18 moves downward under the action of its own gravity until it contacts the limit block 182, and the first engaging tooth 20 is pushed by the ratchet gear 26 to overcome the elastic force of the first elastic member 21 and rotate. Under the action of the gravity of the hazardous chemicals, the spur rack 28 tends to move downward, but the second engaging tooth 24 restricts the reverse rotation of the ratchet gear 26, so the spur rack 28 and the hazardous chemicals will maintain the current height position, and this process is repeated. The user can gradually and labor-savingly lift the hazardous chemicals to a suitable height by shaking the handle 8, making it convenient for people on the truck to transfer the hazardous chemicals to the truck.

[0040] When unloading is required, the device body 1 is rotated on the rotating seat 36, the slide plate 61 is pulled out of the first receiving groove 6, the first supporting plate 33 is rotated around the third rotating shaft 32, the second supporting plate 35 is pulled out from the plate groove 34, and then the second supporting plate 35 is placed on the truck. The gripping part 351 increases the gripping degree between the second supporting plate 35 and the truck, and the dangerous chemicals can be slid through the first supporting plate 33 and the second supporting plate 35 to the ground or other devices for unloading and transportation, which is convenient and labor-saving.

[0041] The present invention can achieve the first labor-saving effect by setting the first transmission plate 7 and the second transmission plate 11 of different diameters. By setting the distance between the cylinder 17 and the front end of the movable rod 14 to be smaller than the distance between the rear end of the cylinder 17 and the movable rod 14, that is, the resistance arm is smaller than the power arm, the second labor-saving effect is achieved by using the lever principle, so that the user can turn the handle 8 to drive the dangerous chemicals to be transported to the truck with little effort, and the user does not need to carry them frequently, so as to prevent the dangerous chemicals from being accidentally broken and affecting the user's personal safety. The first support plate 33 and the second support plate 35 can be adapted to truck containers of different heights, so that the dangerous chemicals can be easily unloaded.

[0042] The components, modules, mechanisms and devices not described in detail in the present invention are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
