detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, the base 1 is the basic component of the present invention, a pair of guide rails 11 are arranged on the top of the base, a support base 12 is provided between the two guide rails, and a threaded screw is installed on the support base for rotation. 13. A handle 14 is provided at the driving end of the lead screw. A mounting plate 2 is arranged above the base, and a screw nut 21 is arranged at the bottom of the mounting plate, and the screw nut cooperates with the leading screw. A slide block 22 is respectively fixed at the bottom of the mounting plate on both sides of the lead screw nut, and the slide block is slidably installed with the corresponding guide rail. The top of the mounting plate is provided with a vertical support rod 31, the first bearing assembly 3 is fixed on the top of the support rod, the outer ring of the first bearing assembly is fixed on the support rod and the first bearing assembly is placed vertically, at the first A rotating block 5 is fixed on the bearing inner ring of the bearing assembly. The other end of the base is also fixed with a vertical support rod, the top of the support rod is fixed with a second bearing assembly 4, the model of the second bearing assembly is the same as the model of the first bearing assembly, and the model of the second bearing assembly The axis is disposed collinearly with the axis of the first bearing assembly. A rotating block 5 is also arranged on the inner ring of the second bearing assembly, and a vertical plate 71 is respectively fixed on the rotating blocks of the first bearing assembly and the second bearing assembly, and the vertical plate is arranged radially along the bearing in the first bearing assembly . A cross arm 51 is respectively fixed on the top and bottom of the vertical plate, and the cross arm is vertically arranged with the vertical plate.
