Scale mark indicating the lifting height of workbench is also provided on rotating handle 10, the height of workbench can be accurately adjusted. Embodiment
[0029] The embodiment is based on embodiment 1 and provides a manual lifting platform, with the difference that:
[0030] The workbench comprises a top plate 4 and a stone plate 5 placed on the top plate 4, and the stone plate 5 can also be a plate made of other anti-static materials, wherein the top plate 4 is connected with the two side plates 2 by screws, and a stand column 6 is further arranged below the top plate 4, which is always in contact with the cam 8.
[0031] As shown in Figure 1 , Figure 2 , four guide rail groups 7 are arranged, each of which is installed between a side plate 2 on one side and the stator base 3, and both of the two guide rail groups 7 are installed close to the edge of the stator base 3, and the four guide rail groups 7 realize the support of the top corners of the workbench. A side edge protrusion is further arranged on the side wall of the stator base 3, which limits the guide rail group 7, and the guide rail group 7 can realize the guiding effect of the upward and downward movement of the workbench, avoiding the deflection of the movement of the workbench.
[0032] The guide rail group 7 is a cross ball guide rail group 7, which comprises a first rail and a second rail, the first rail is installed on the side plate 2, and the second rail is installed on the side wall of the stator base 3, the first rail moves up and down on the side plate 2, and the first rail slides on the second rail, and a ball is arranged between the first rail and the second rail to reduce the resistance of the relative movement of the first rail and the second rail.
[0033] The side plate 2 is in a U-shaped structure, the opening is towards the side wall of the stator base 3, and the guide rail group 7 is installed in the gap formed by the stator base 3 and the side plate 2, a locking screw 9 for locking the height of the workbench is arranged at the end of the side plate 2, one end of the locking screw 9 acts on the guide rail group 7, and the other end is located outside, the locking and opening of the guide rail group 7 are realized by manual adjustment, when locked, the positions of the first rail and the second rail are locked by the locking screw 9, the rotating handle 10 cannot be rotated, the workbench at the moving height also cannot be lowered, and the use of the workbench is realized.
