The knife handle side is equipped with groove, and knife rest is equipped in the groove, and the knife rest is equipped with cotter way, is equipped with rotation in the cotter way
Axis, the side of the knife rest are equipped with embedding headgear, and the embedding headgear is equipped with blade, the knife spine of the blade far from the side of rotary shaft
Corrugated, the lower end of the knife rest is equipped with connection buckle, and the connection buckle is in concave, and the connection buckle is far from rotation
The side top of shaft is equipped with magnet, and the groove side is equipped with the catching groove to match with connection buckle, the catching groove bottom
Portion is equipped with the catching groove iron plate for fixed magnet.
Further, the protrusion in the knife handle outer side wall surface is in long strip and is evenly distributed in knife handle two sides.
Further, the embedding headgear and rotary shaft are attached by cotter way.
Further, the embedding headgear is equipped with the connection bolt for being fixedly connected with blade with the junction of blade.
Further, the side of the blade is equipped with the connecting screw hole for connecting bolt-through.
Further, the middle part on the top of the connection buckle is equipped with for reducing the slow of pressure between connection buckle and catching groove
Punching.
Further, the buffer substrate tablet is made of epoxide resin material.
The utility model is had the beneficial effect that compared with prior art when using surgical knife, presses connection
Buckle, connection buckle band movable knife rack under rotary shaft effect rotate, the blade of knife rest side are screwed out out of groove, is connected at this time
Buckle can just stick into inside the catching groove on groove top side wall, the catching groove iron on magnet and catching groove in connection buckle
The problems such as piece mutually attracts, and increases fixed force, would not shift in use process of performing the operation in this way, the top of connection buckle
The buffer substrate tablet at middle part can reduce the pressure generated when connection, extend the service life of connection buckle, while handle side walls table
Protrusion on face increases the frictional force between the palm of the hand and knife handle, prevent in the course of surgery knife handle easily slide, avoid medical treatment
The generation of accident, and accomplished that structure is simple, operation is easy, and time saving and energy saving, the work for greatly reducing medical worker is difficult
Degree.
