[0023] Figure 1 、 2 It is shown that the lead screw 7 is engaged with the lead screw nut 6. The upper end of the lead screw 7 is equipped with a handle 8 for rotating the lead screw 7. The lower end of the lead screw 7 passes through the circular hole of the top plate 5 and is rotatably connected to the lead screw rotating sleeve 9. The connection structure between the lead screw 7 and the lead screw rotating sleeve 9 is as follows: the lower end of the lead screw 7 has an annular protrusion 16, and the lead screw rotating sleeve 9 is composed of two semicircular sleeves. The lower inner walls of the two semicircular sleeves respectively have semicircular grooves. The semicircular grooves at the lower parts of the two semicircular sleeves relatively form a circular groove. The circular groove matches the annular protrusion 16 at the lower end of the lead screw 7. The annular protrusion 16 at the lower end of the lead screw 7 is embedded in the circular groove at the lower end of the lead screw rotating sleeve 9.
