The end plate 4232 is an outer hexagonal plate and can be used in cooperation with tools such as a wrench, or a force application rod is arranged on the end plate 4232, and the end plate 4232 and the screw body 4231 can be driven to rotate by holding the force application rod, so that time and labor are saved. One end of the screw body 4231 is welded and fixed with the end plate 4232, the screw body 4231 penetrates through the guide sleeve 421 and is in threaded connection with the guide sleeve 421, and the other end of the screw body 4231 is rotatably connected with the wear-resistant sleeve 4234 through a bearing 4233. The wear sleeve 4234 and the bearing 4233 are both positioned in the guide sleeve 421, and the wear sleeve 4234 is used for abutting against the outer surface of the guide rod 422. So design, wear-resisting cover 4234 and guide bar 422 contact, when needs lock guide bar 422 and guide bar 421, knob screw body 4231's in-process, screw body 4231 can rotate for wear-resisting cover 4234, wear-resisting cover 4234 and the back of guide bar 422 butt continue to rotate screw body 4231, screw body 4231 can not drive wear-resisting cover 4234 and rotate for guide bar 422, but compresses tightly on guide bar 422 through wear-resisting cover 4234, can not produce relative rotation between wear-resisting cover 4234 and the guide bar 422, and the wearing and tearing are little, long service life.

The novel operation table that this embodiment provided can accurately adjust the angle of the bed body 200 for the horizontal plane according to the on-the-spot demand to behind angle regulation, can keep bed body 200 unchangeable with horizontal angle, stability is high, and the security is high. When the patient lies flat or lies on the bed body 200, the shoulder of the patient is abutted to the limit pillow 300, the limit pillow 300 is utilized to limit the patient to slide relative to the bed body 200, the comfort level is improved, and the operation is convenient to carry out.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
