Handles for facilitating its rotation are evenly installed on the screw sleeve in the circumferential direction. A guide sleeve for passing the support screw is provided inside the conical base. The support screw is passed through the guide sleeve and is threadedly connected to the screw sleeve. A support block for easy disassembly and assembly is installed on the top of the support screw. A guide groove is axially opened on the support screw, a threaded hole threadedly connected to the limit screw is radially opened on the conical base, a through hole coaxial with the threaded hole is radially opened on the guide sleeve, and one end of the limit screw passes through the through hole of the screw sleeve and extends into the guide groove on the support screw.

[0006] The support block is provided with reinforcing ribs for improving its strength and rigidity.

[0007] The conical base is symmetrically provided with anti-skid handles along the radial direction for facilitating the movement of the device.

[0008] Beneficial effects of the utility model:
