Description

One kind using replacer convenient for screw threads for fastening dismounting

Technical field

The utility model relates to a kind of fastener replacers, especially a kind of to use replacer convenient for screw threads for fastening dismounting.

Background technique

The tools such as the existing screwdriver sold on the market, in order to laborsaving handy, screwdriver head and handle portion are all very long, use Get up and be also required for enough operating spaces, and in the daily work, people are in assembly or repair demolition part, often Encounter that operation by human hand space is small, tool is put to enter or shorter screwdriver can enter but operate cannot be firmly or laborious Situations such as, come to work belt difficult or inconvenient；There are some components that detachable maintaining is needed to maintain in fascia, such as The disassembly of air-conditioning box damper motor, pollen filter etc. is all rapid wear attrition component, cannot maintain every time need to tear instrument board open it is total At or the big total member in periphery, movement is big in this way, the time is long, working hour is more, it is also big to damage to the disassembly repeatedly of instrument board, therefore It needs to be implemented only through the part dismantlement work to instrument board part small range or small space.

Summary of the invention

The purpose of this utility model is that: in view of the above-mentioned problems of the prior art, proposing a kind of convenient for screw threads for fastening Dismounting replacer realizes small spatial operation, laborsaving, easy disassembly work and carries, and low in cost, and versatility is good and just In implementation.

In order to reach the goals above, one kind of the utility model convenient for screw threads for fastening dismounting use replacer, including handle and There are the body of rod in driver bit, the driver bit side, and driver bit is mounted on handle by the body of rod, it is characterised in that: described Handle is in coronal distribution along its thickness, and coronal handle surrounding is dismounting working face, has anti-skid structure on the dismounting working face.

Further, the dismounting working face is matched with manpower gripping surface.

Further, the anti-skid structure is strip fold building, with sequentially upfold, falls into pleat continuous arrangement.

Further, the anti-skid structure is the cancellated structure of continuous concave-convex form, and the cancellated structure is for straight line or tiltedly Line arrangement.

Further, the anti-skid structure is covered on dismounting working face.

Further, the driver bit is fixedly connected by the body of rod with handle composition, or is detachably connected.

Further, it when being fixedly connected when handle and the body of rod composition, is equipped at handle bottom surface center and to be clamped with the body of rod Blind hole, the blind hole and the body of rod, which are formed, to be interference fitted.

Further, when handle and body of rod composition are detachably connected, have on handle with the matched central through hole of the body of rod, Magnetic adsorptive material, the central through hole other side removable plug body of rod are added in the central through hole side away from handle upper bottom surface.

Further, the lightening hole of through-hole type is spaced apart on the handle.

Still further, the driver bit is a word cutter head, cross cutter head, special-shaped cutter head.

The utility model the utility model has the advantages that the replacer mainly makes the working face anti-skid structure of handle, and then increase hand With the frictional force of working face, it is not easy to skid；The opereating specification of manpower is also set to become larger simultaneously, conducive to the dismounting of small space components Problem can also adjust operation torsion by hand coronal side size Control, and effective solution people are under small space to zero The problems such as dismounting maintenance of part threaded fastener is inconvenient.
