By setting the limiting rod 35, the height position of the lifting frame 32 can be adjusted along the lifting screw 31 during the rotation of the lifting screw 31.

[0021] There are at least two limit rods 35 , which are symmetrically distributed frontally and rearwardly around the axis of the lifting screw 31 . The two limit rods 35 enhance the stability of the lifting frame 32 during height adjustment.

[0022] like Figure 3 and Figure 4 As shown in the figure, a positioning assembly 5 is installed between the inner cavity of the lifting screw 31 and the mounting plate 4. The positioning assembly 5 can be used to position the lifting frame 32 after the lifting screw 31 completes the adjustment of the position of the lifting frame 32, so that the position remains stable and the vibrator body 1 will not rotate due to the vibration generated during operation, thereby causing the lifting frame 32 to shift in height.
