[0019] The utility model is further described below with reference to the accompanying drawings. Embodiment 1

[0020] like Figures 1 to 3 As shown, the upper end of the bottom plate 1 is connected to the lower base 2, a sleeve 3 is provided in the lower base 2, a lead screw 4 is provided in the sleeve 3, an adjusting nut 5 is provided on the lead screw 4, an upper support plate 6 is connected to the upper end of the lead screw 4, and upwardly bent fenders 7 are provided on the left and right sides of the upper support plate 6, and the inner side of the fender 7 is connected to a roller 7-1 for facilitating the sliding of the busbar, a plurality of fixing holes 9-1 of different heights are provided on the outer wall of the lower base 2, and a plurality of fixing holes 9-2 matching the fixing holes 9-1 are provided on the outer side of the middle sleeve 3.

[0021] A guide groove 4-1 is arranged in the up-down direction on the outside of the lead screw 4, and a threaded limit hole 3-1 matching the position of the guide groove 4-1 is arranged on the outside of the sleeve 3. When in use, the limit screw is inserted into the limit thread hole 3-1 and the guide groove 4-1 respectively to prevent the lead screw 4 from rotating and guide the up-down movement of the lead screw 4.

[0022] The threaded limiting hole 3 - 1 is a countersunk hole. In specific use, after the limiting screw is inserted into the threaded limiting hole 3 - 1 , the up and down movement of the sleeve 3 in the lower base 2 is not affected.

[0023] The upper end of the sleeve 3 is provided with a limiting step 10. When the sleeve 3 moves to the upper end of the lower base 2, the limiting plate 10 is stuck on the upper end of the lower base 2 to play a limiting role.

[0024] The bottom plate 1 is provided with a plurality of threaded holes 12 for mounting universal wheels. The bottom plate 1 is connected to a universal wheel 15 at its lower end, so as to facilitate the movement of the trolley of the utility model. When used specifically, the universal wheel 15 is selected to have a brake function to ensure the stability of the utility model during use.

[0025] One end of the adjusting nut 5 is connected to the handle 13, so that the height of the lead screw 4 can be adjusted by adjusting the nut 5, thereby adjusting the height of the entire assembly trolley.

[0026] An upper support seat 14 is provided at the lower end of the upper support plate 6, and the upper support seat 14 is provided with two threaded holes that cooperate with the lead screw 4. After the upper support seat 14 and the lead screw 4 are assembled, the upper support plate 6 is fixed on the upper support seat 14 and the lead screw 4 by bolts, and the three are fixed by bolts to play a supporting role, prevent the lead screw from being displaced during use, ensure the stability of the utility model during use, and thus ensure the stability of the busbar assembly.

[0027] When the utility model is used, the staff can adjust the adjusting nut 5 to change the height of the screw 4 as needed, so that the busbar assembly trolley can adjust the tooling to adapt to busbars of different heights and diameters. When the busbar is short or the diameter is too large, the adjusting nut 5 is adjusted to drive the upper support seat 14 and the upper support plate 6 downward through the screw 4 to reduce the tooling height; when the busbar is high or the diameter is too small, the adjusting nut 5 is adjusted to drive the upper support seat 14 and the upper support plate 6 upward through the screw 4 to increase the tooling height.

[0028] When the screw 4 is not adjusted to a high enough height, the fixing hole 1 9-1 at different heights on the outer wall of the lower base 2 is fixed to the fixing hole 2 9-2 on the outer side of the intermediate sleeve 3 to change the height of the sleeve 3 relative to the lower base 2, thereby further adjusting the height of the busbar assembly trolley. Embodiment 2

[0029] This embodiment only describes the differences from the first embodiment, and the similarities are not described again.

[0030] The difference between this embodiment and the first embodiment is that Figures 4 to 5 As shown, in this embodiment, a bearing 16 is provided between the sleeve 3 and the adjusting nut 5 .

[0031] When the busbar is heavy, the friction between the adjusting nut 3 and the sleeve 5 is large, and the adjustment may be difficult. In this embodiment, a bearing is added between the sleeve 3 and the lead screw 4 to ensure that the adjusting nut 5 rotates smoothly.
