Abstract

The utility model discloses a screwdriver for measuring level and verticality. A long groove which is parallel to the base face of a grab handle is mainly arranged on the grab handle, and a liquid transparent air bubble instrument relative to the size and form of the long groove is installed in the long groove. A groove socket vertical to the base face is arranged on the tail of the grab handle, and a liquid transparent air bubble vertical instrument relative to the size and form of the groove socket is installed in the groove socket. While in use, as long as the screwdriver is arranged on a work piece crossly or vertically, the level and verticality of the work piece can be measured. The utility model has the advantages of convenient use and portability, is used at all hours and achieves multifunctional effect.

Description

Screwdriver for measuring level and verticality

The utility model relates to a kind of instrument, is meant the screwdriver of energy measurement level and perpendicularity especially.

Screwdriver on the market generally all is made up of cutter hub, lever, all workpiece of combining with screw, must be with screwdriver with its locking and decomposition, only can carry out the rotation of screw, error is bigger, for the workpiece combination of the level of being particular about or perpendicularity, must proofread and correct with level meter or vertical collimator separately, tighten up with screwdriver then, very inconvenient.

The purpose of this utility model is to provide a kind of can measure levelness, but the screwdriver of measuring vertical degree again is very convenient to use, can carry, and reaches the effect of multipotency at one stroke.

The purpose of this utility model is achieved in that the screwdriver of measurement level and perpendicularity, mainly is provided with the long recess parallel with the lever datum level on lever, relative long recess size shape, interior dress liquid-transparent air-bubble level; Vertical this datum level of the handle tail that is in one's hands is provided with a groove cave, opposed slot cave size shape, interior dress liquid-transparent bubble vertical collimator.

Need only or stand up on workpiece the screwdriver traverse during work, then can measure the levelness and the perpendicularity of workpiece, use easily, can carry, use at any time, reach the effect of multipotency at one stroke.

Specific embodiment of the utility model will further specify by the following drawings.

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is a stereogram of the present utility model.

Fig. 3 is profile of the present utility model (one).

Fig. 4 is profile of the present utility model (two).

Fig. 5 is an enforcement view of the present utility model ().

Fig. 6 is an enforcement view of the present utility model (two).

Referring to Fig. 1～4, the screwdriver that can be used for measurement level and perpendicularity in a kind of work, mainly use on the cambered surface Screwdriver handle 10 more, calibrated processing is provided with the datum level 11 of a tool straight parallel degree, on these datum level 11 relative cambered surfaces, be provided with the long recess 12 of parallel this datum level 11, the size shape of relative long recess 12, interior dress liquid-transparent air-bubble level 20; Vertical this datum level 11 of afterbody at lever 10 is provided with a groove cave 13, the size shape in opposed slot cave 13, interior dress liquid-transparent bubble vertical collimator 30, (the peak that level meter 20 poles are horizontal, be advisable to be no more than the cancave cambered surface eminence, do not influence the lever grasping), wherein the liquid-transparent air-bubble level is a round bar shape, liquid-transparent bubble vertical collimator is a hemispherical.

Shown in Fig. 5～6, during use, need only be with screwdriver horizontal or vertically-arranged, the datum level 11 of lever 10 is abutted on the transverse plane or vertical surface of workpiece thing, can directly measure the levelness and the perpendicularity of workpiece thing by level meter 20 or vertical collimator 30, implement immediately to proofread and correct, bring into play multi-function action of the present utility model, improved its practical value.

Claims

1, a kind of measurement level of forming by cutter hub and lever and the screwdriver of perpendicularity, it is characterized in that: lever is provided with the long recess parallel with the lever datum level, long recess size shape relatively, interior dress liquid-transparent air-bubble level; Vertical this datum level of the handle tail that is in one's hands is provided with a groove cave, opposed slot cave size shape, interior dress liquid-transparent bubble vertical collimator.

2, the screwdriver of measurement level according to claim 1 and perpendicularity is characterized in that: the liquid-transparent air-bubble level is a round bar shape, and liquid-transparent bubble vertical collimator is a hemispherical.
