Abstract

The utility model relates to a reversible wrench comprising a handle, a ratchet jacket, a ratchet cover and a ratchet portion. The technical characteristics include that the handle and the ratchet jacket are welded to one piece structure, and the rim of the ratchet is arranged with a ratchet pin which is engaged with a ratchet tooth, the ratchet pin allows the ratchet to rotate along one direction, and restricts rotating in opposite direction. The utility model has the advantages of simple structure, heavy intensity, convenient utilization, reversible manner and the like.

Description

The bone surgery special use can reverse spanner
Technical field:
This utility model relate to a kind of in the human body medical apparatus and instruments of output medium, specifically a kind of bone surgery special use can reverse spanner.
Background technology:
In the bone surgery process, often to use the spanner of fastening nut or bolt, commonly used is that interior hexagonal is fixed or the scalable spanner now, angle of every swivel nut all will be lifted spanner during use, changes angle and is inserted in nut more again and rotates, so repeatedly, efficient is very low, owing to lift the displacement that is easy to cause fixed apparatus repeatedly, operation process and postoperative effect is produced harmful effect.
Summary of the invention:
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, and a kind of simple structure is provided, and bone surgery special use easy to use can reverse spanner.
For achieving the above object, this utility model can be realized by following measure: the head at spanner is provided with a ratchet, and its technical characterictic is that the outer of ratchet is provided with ratchet pin, ratchet pin and hook tooth engagement, ratchet pin allows ratchet to rotate to a direction, and restriction is rotated round about.
This utility model is simple in structure, and is easy to use, can reverse, and significantly reduced palikinesia unnecessary in the operation process.
Description of drawings:
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of ratchet.
Fig. 3 is the side view of ratchet pin.
The specific embodiment:
As can be seen from Figure 1, this utility model handle 6 and ratchet overcoat 3 integrally welded structures, ratchet lid 2 are fixed on ratchet 1 in the ratchet overcoat 3, and spring 5 just in time meshes ratchet pin 4 outside ratchet pin 4 is pushed to the ratchet picture.
When this utility model uses, because ratchet pin 4 limits the rotation direction of ratchet 1, driving ratchet 1 when handle 6 rotations rotates together, ratchet pin 4 no longer limits the rotation direction of ratchet 1 when turning handle 6 round about, handle 6 can return original position again and ratchet 1 keeps original position motionless, and turning handle 6 can screw nut so repeatedly.Same principle with handle 6 counter-rotatings, can unload nut.
