Abstract

The utility model relates to a screwdriver. The screwdriver comprises a hollow tool holder, wherein an open slot is formed in one side of the hollow tool holder; a plurality of regulating tanks are arranged on one side where the open slot is formed, of the tool holder; a tool bit is inserted in the front end of the tool holder; a bulge arranged on one side of the tool bit and a clamping groove formed inside the tool holder are clamped and matched with each other; the rear end of the tool bit is movably connected with one end of a control push rod arranged in the open slot; the other end of the control push rod is clamped with the regulating tanks arranged on the tool holder. With the adoption of the technical scheme, the structural design of the screwdriver is reasonable, and through the matched clamping of the control push rod and the regulating tanks arranged on the tool holder, the length of the tool bit of the screwdriver can be adjusted at random as required, so that not only is a protective effect on the tool bit realized when the torque force is larger, but also a screw in a deeper groove can be touched to realize elastic operation, and accordingly, for people, the use is greatly facilitated.

Description

A kind of screwdriver

Technical field:

The utility model relates to a kind of screwdriver.

Background technology:

The screwdriver used at present, although kind is a lot, but the length of its cutter head all can not arbitrarily be regulated, if cutter head is long, when torsion is larger, be easy to cutter head is caused to damage, if cutter head is too short, be located at the screw in deep groove for some, can't touch screw and cause and can't use, bring inconvenience to people.

The utility model content:

The utility model is in order to make up the deficiencies in the prior art; a kind of screwdriver is provided; its reasonable in design; the length of driver bit can arbitrarily be regulated as required; both can when torsion is larger, to cutter head, play a protective role; the screw that can touch again in darker groove carries out the degree of tightness operation, greatly facilitates people's use, has solved problems of the prior art.

The utility model is to solve the problems of the technologies described above adopted technical scheme to be:

A kind of screwdriver, comprise a hollow handle of a knife, be provided with an open slot in hollow handle of a knife one side, be provided with several regulating tanks on the handle of a knife of open slot one side, at the handle of a knife front end cutter head of pegging graft, the projection that the is located at cutter head one side clamping that matches with draw-in groove in being located at handle of a knife, the cutter head rear end is movably connected with an end that is located at the control push rod in open slot, controls the other end and the regulating tank phase clamping be located on handle of a knife of push rod.

The utility model adopts such scheme; reasonable in design; by controlling push rod, with the regulating tank clamping on being located at handle of a knife, coordinate; can be as required the random length of set screw jet blade; both can when torsion is larger, to cutter head, play a protective role; the screw that can touch again in darker groove carries out the degree of tightness operation, greatly facilitates people's use.

The accompanying drawing explanation:

Fig. 1 is structural representation of the present utility model.

In figure, 1, handle of a knife, 2, open slot, 3, regulating tank, 4, cutter head, 5, projection, 6, draw-in groove, 7, control push rod.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and, in conjunction with its accompanying drawing, the utility model is elaborated.

As shown in Figure 1, a kind of screwdriver, comprise a hollow handle of a knife 1, be provided with an open slot 2 in hollow handle of a knife 1 one sides, be provided with several regulating tanks 3 on the handle of a knife 1 of open slot 2 one sides, at the handle of a knife 1 front end cutter head 4 of pegging graft, be located at the clamping that matches with draw-in groove 6 in being located at handle of a knife 1 of the projection 5 of cutter head 4 one sides, cutter head 4 rear ends are movably connected with an end that is located at the control push rod 7 in open slot 2, control the other end and the regulating tank 3 phase clampings that are located on handle of a knife 1 of push rod 7.

During use, according to actual working condition, can front and back push-and-pull control push rod 7 cutter head 4 be adjusted to suitable length, then will control push rod 7 rear ends and be installed on interior the fixing of corresponding regulating tank 3 on handle of a knife 1, now can carry out the degree of tightness operation, during work, projection 5 matches with draw-in groove 6, can prevent that cutter head 4 from rotating, guarantee cutter head 4 normal operations.Adopt screwdriver of the present utility model; reasonable in design; by controlling push rod 7, with regulating tank 3 clampings on being located at handle of a knife 1, coordinate; can be as required the random length of set screw jet blade 4; both can when torsion is larger, to cutter head 4, play a protective role; the screw that can touch again in darker groove carries out the degree of tightness operation, greatly facilitates people's use.

The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
