[0002] Currently, with the development of technology, various types of cargo transportation tools have emerged. Among them, the lifting platform is a mechanical device that enables the transportation of people or goods across heights. Lifting platforms are further divided into several types, including scissor lifts, telescopic boom lifts, and articulated boom lifts. Scissor lifts are widely used in production and daily life.

[0003] A search revealed existing technology (publication number: CN221821789U), which describes "a scissor lift platform, belonging to the field of cargo transportation technology. The scissor lift platform includes a lifting platform, a base, a scissor mechanism, a drive mechanism, and a guide mechanism. The lifting platform is positioned relative to the base. One end of the scissor mechanism is connected to the lifting platform, and the other end is connected to the base. The drive mechanism is adapted to drive the scissor mechanism to rotate, thereby raising and lowering the lifting platform. The guide mechanism is located on at least one side of the scissor lift platform and is adapted to be supported on the ground and slidably connected to the lifting platform. In this application, the guide mechanism can play a guiding and limiting role during the raising and lowering process of the lifting platform, resulting in good stability of the lifting platform."

[0004] While existing scissor lift platforms have achieved stability, they still have some shortcomings: the conveyor rollers inside existing scissor lift platforms, such as those mentioned in the patent literature, can only be used for transporting goods. When personnel need to work at height, the conveyor rollers cannot ensure that personnel can stand stably, resulting in the limited functionality of existing scissor lift platforms. Similarly, existing scissor lift platforms used for lifting at height cannot facilitate the transport of goods. Utility Model Content

[0024] In this embodiment, the base 1, the upper structure, the multi-stage telescopic rod 2, and the drive assembly 3 constitute the main structure of the scissor lift platform involved in this application.

[0025] The scissor-type support legs and hydraulic cylinders installed on the inner side of the base 1 adopt the same main structure as the existing scissor lift, realizing lifting operation, and a start button box for controlling the hydraulic cylinder is provided at the upper end of the top frame 13.

[0026] The multi-stage telescopic rod 2 has four sets, which are respectively located at the four corners of the base 1. The multi-stage telescopic rod 2 is constructed by using a multi-sleeve sliding end connection method to achieve stable guidance for the scissor-type outriggers and provide lateral stability.

[0027] The platform 11 is designed as a rectangular frame structure, and the railings 12 are respectively set at the four corners of the platform 11. Goods enter from the open space on one side of the railing 12 and exit from the open space on the other side.

[0028] like Figures 2 to 4 In the middle, the inner sidewall of the railing 12 has a vertical sliding groove 121, and the outer wall of the railing 12 has two threaded holes 122, one above the other, which communicate with the vertical sliding groove 121. A screw-on threaded rod 123 is threaded into the threaded hole 122. A slider 141 is connected to the outer end of the pedal 14, and a positioning hole 142 is provided at the outer end of the slider 141. The slider 141 is slidably connected to the vertical sliding groove 121, and the screw-on threaded rod 123 passes through... The threaded hole 122 is inserted into the positioning hole 142.
