2. the chuck is made of all metal, the outer ring is designed with the tooth grids, various types of drill bits can be conveniently matched and replaced, the chuck can be completely matched with various drill bits of the existing surgical electric drill and can be easily replaced, the drill bits can be replaced by bare hands without matching with other tools, and the operation time can be greatly saved in the operation process of competing for seconds;
3. the hand drill is of a pure mechanical structure, so that the whole sterilization treatment can be conveniently realized, and the hand drill is more suitable for being used in an operation environment needing complete sterility;
4. the hand drill adopts a pure mechanical design, the gear ratio of the handle and the connecting screw rod is fixed, the drilling distance of the drill bit can be accurately controlled according to the number of turns of the rocking handle, and in a surgical operation requiring accurate control of the drilling depth, the hand drill can be finely operated by a doctor and matched with a stopper of the drill bit, so that the operation purpose of the operation is better achieved.
The invention has simple structure, convenient use, lower cost, easy sterilization treatment, easy control of the depth, the force and the drilling speed of the drilled hole, no vibration in the operation process and no risk of burning human tissues near the drilled hole.
The hand drill can also be widely used for various purposes such as playing, woodcarving, fine handwork, DIY model and the like, and can be matched with various types of drill bits used at present to carry out the operation needing fine drilling.
