The lifting device also comprises a stepping motor fixedly arranged on the vertical plate and located between the first linear guide and the second linear guide, a vertical lead screw fixedly connected to an output shaft of the stepping motor, a screw sleeve sleeved on the vertical lead screw and screwed to the vertical lead screw, and the screw sleeve is fixedly connected to the mounting plate.

[0004] However, the CT equipment needs to be positioned according to actual usage during actual use, and the above application can only be adjusted in the vertical direction, while the position adjustment during use cannot be well taken into account, which is a constraint in actual use. Utility Model Content

[0005] The utility model provides a scanning cantilever lifting device, aiming to solve the problem that the prior art can only perform vertical adjustment, but cannot take into account the position adjustment during use, resulting in constraints in actual use.

[0006] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0007] Preferably, a rubber pad is fixedly connected to the outer wall of the pressing plate.

[0008] Preferably, the support arm comprises a fixed tube, and a telescopic tube is slidably connected to the inner wall of the fixed tube, a fastening bolt is threadedly connected to the lower surface of the fixed tube, and a friction plate is arranged on the upper end of the fastening bolt.

[0009] Preferably, the friction plate is rotationally connected to the fastening bolt.

[0010] Preferably, the outer wall of the lower end of the fastening bolt is provided with anti-slip grooves.

[0011] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0012] The personnel operate the controller to control the start and stop of the electric screw slide. The arm can be raised and lowered by moving the moving end of the electric screw slide. The equipment is installed on the mounting plate, which facilitates the height adjustment of the equipment. The personnel presses the pressure plate downward to move the back plate downward and away from the lower surface of the vertical pole. The personnel rotates the vertical pole to adjust the orientation of the equipment, thereby improving the applicability of the equipment. After adjusting the orientation, the personnel releases the pressure plate, and the elastic force of the spring restores the back plate, causing the back plate to rise and contact the vertical pole. The convex teeth on the vertical pole enter the tooth grooves on the back plate, thereby causing the back plate to limit the rotation of the vertical pole, preventing the equipment from rotating during operation and improving the stability of the equipment.
