[0002] Radiotherapy machines play an important role in the medical field. They are mainly used to treat malignant tumors. They are a radiotherapy method that uses radiation to treat malignant tumors. The principle is to use electromagnetic radiation to act on tumor cells, thereby causing tumor cell necrosis. The patient lies on the bed, and then the treatment machine head is used to perform radiotherapy on the patient. However, when the radiotherapy machine is working, the treatment machine head may collide with both sides of the bed, thereby causing damage to the treatment machine head and causing serious losses. In addition, the anti-collision device is inconvenient to disassemble and assemble, and it is inconvenient to repair and replace it after damage. In view of this, in-depth research was conducted on the above-mentioned issues, which led to the present case. Utility Model Content

[0021] The inner wall of the locking device 24 is installed with a threaded rod 20, and the outer wall of one end of the threaded rod 20 is threadedly installed with a locking rod 18, and the outer wall of the positioning plate 8 is provided with a locking groove 17 matched with the locking rod 18;

[0022] The outer wall of the other end of the threaded rod 20 is installed with a second bevel gear 23, the outer wall of the locking device 24 is installed with a knob 21, and one end of the knob 21 is connected to the first bevel gear 22, and a meshing transmission structure is formed between the first bevel gear 22 and the second bevel gear 23;

[0023] The inner walls on both sides of the locking device 24 are provided with limiting grooves, and both sides of one end of the locking rod 18 are movably connected to the limiting grooves through limiting blocks;

The threads cooperate to move the locking rod 18 to the side away from the locking groove 17, which is convenient for disassembly of the protective device 16. The locking rod 18 is moved into the locking groove 17 by reversing the knob 21, which is convenient for installation of the protective device 16, thereby facilitating disassembly and assembly of the protective device 16.

[0025] Embodiment 2: The inner side of each protective device 16 is provided with a cavity 10, and the inner side of each cavity 10 is provided with a piston 11;

Through the expansion of the airbag 9, a further buffering effect is achieved, thereby preventing the collision between the bed 1 and the head body 2.
