during use, a patient is stopped on the bed body 1, the head is positioned between the two telescopic blocks, according to the difference of the head size of the patient, the second tightening screw 11 is screwed inwards, the second tightening screw 11 drives the movable block 10 to move inwards, the two movable blocks 10 fix the two sides of the head, meanwhile, the third tightening screw 23 is screwed downwards, the third tightening screw 23 drives the positioning plate 24 to move downwards, the positioning plate 24 fixes the upper part of the head, the arranged protective pad 25 can protect the upper part of the head, and the head is prevented from being damaged due to the overlarge force of the positioning plate 24; the electric push rod 12 is started to contract, the electric push rod 12 drives the pressing block 15 to move towards the direction close to the second tightening screw 11, and the pressing block 15 tightly abuts against the second tightening screw 11 to prevent the second tightening screw 11 from loosening in the using process; after the operation is finished, the third elastic screw 23 is unscrewed upwards, and the pressing block 15 automatically moves upwards under the action of the restoring force of the return spring 13, so that the head of the patient can be conveniently moved out; before the head is positioned, the small electric cylinder 21 is started to stretch, the small electric cylinder 21 drives the movable block 18 to move up and down, and the movable block 18 drives the headrest 19 to move to a proper height, so that the problem that the head height is not convenient to adjust and position is solved; through the two telescopic columns 20, the movable block 18 can be stably adjusted in an up-and-down movement mode.
The invention is not described in detail, but is well known to those skilled in the art.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
