Further, the screw thread that described cushion block is connected with saw bone cylinder is left hand thread or right-handed thread.
The using method of adjustable-depth annular bone saw：
The first step, selects the cushion block of suitable length to be arranged in saw bone cylinder according to saw bone depth；
Second step, by connection handle, adjustable-depth annular bone saw is arranged on rig；
3rd step, when the screw thread that cushion block is connected with saw bone cylinder is left hand thread, starts rig rotate counterclockwise saw bone；Cushion block
When being right-handed thread with the saw screw thread that is connected of bone cylinder, startup rig turns clockwise saw bone；
4th step, after cushion block contact bone surface, the effect cushion block due to frictional force stops operating, and saws bone cylinder and continue to turn
Move so that cushion block screws out from screwed hole, thus the circular saw of saw bone cylinder is lifted off sawing bone surface.
The invention has the advantages that：
1. the function of limit bone saw cuts osseous tissue depth is realized by changing the cushion block of different length；
2. do not need to saw bone while observing penetraction depth using the present invention, easy to operate；
3. the accident of Transitional cut will not occur using the present invention, safety coefficient is high；
4. the setting of chip-removal hole is it can be avoided that chip hinders saw bone；
5. left hand thread engagement rotate counterclockwise or right-handed thread cooperation turn clockwise, and enable to cushion block contact bone
Screw out from screwed hole behind surface, thus circular saw is lifted off sawing bone surface, it is to avoid the generation of Transitional cut, can also keep away simultaneously
Exempt from cushion block top surface in bone surface spin friction, cause bone injury.
