Abstract

The utility model discloses a screwdriver, which mainly comprises a screwdriver head, a connecting rod and a handle, wherein the screwdriver head is connected with the handle through the connecting rod, the screwdriver head comprises a head base and two operating levers, a horizontal through groove is formed on the head base, and the operating levers are symmetrically arranged inside the through groove in a detachable manner. The screwdriver provided by the utility model is specially used for screwing nuts or bolts of a screwing groove axially arranged, so as to achieve simpler and more convenient operation of the nuts or the bolts and normal detachment of the nuts or the bolts under the condition of slippery teeth; the screwdriver avoids the condition that the detachment can only be finished by cutting up the nuts or cutting off bolt rods before, thereby being more labor saving and convenient and dispensing with damage on equipment; and horizontal space can not be occupied in axial operation, and the screwdriver can also be normally used in smaller space.

Description

Screwdriver

Technical field

The utility model relates to a kind of screwdriver, and particularly a kind of axial rotary that is exclusively used in is established the nut that turns groove or the screwdriver of screw.

Background technology

Nut, screw are that mechanical field locking member, especially hex nut, screw commonly used are seen everywhere in people's life especially.Existing hex nut and screw all have six sidewalls, become regular hexagon, operate by monkey spanner or hexagon wrench during use.In productive life; run into the situation that nut, screw get rusty with age through regular meeting; corner angle are become fragile; or repeatedly turn in the process impaired and cause sliding tooth; make that wrench can't the locking screw parent and cause and shirk difficulty; this moment is not owing to there is other impetus; make various tool all can't operate to it; run into this situation; usually can only shred nut or cut off screw rod and finish dismounting, waste time and energy, and damage equipment easily; and present nut, screw can only carry out turning of warp-wise (laterally), and the space hour just can't be operated.A kind ofly can provide one second to put forth effort operating point at the nut that turns groove of axially offering two symmetries or screw (as depicted in figs. 1 and 2), can solve above-mentioned deficiency, but do not have special-purpose screwdriver to operate such nut and screw now, make troubles for actual the use.

Summary of the invention

The purpose of this utility model is a kind of convenient disassembly that provides for the deficiency that solves above-mentioned technology, is exclusively used in axial rotary and establishes the nut that turns groove or the screwdriver of screw.

In order to achieve the above object, the screwdriver that the utility model is designed, it mainly comprises driver bit, connecting rod and handle, driver bit is connected with handle by connecting rod, described driver bit is made up of headstock body and two action bars, described headstock body is provided with horizontal groove, and described action bars detachably is symmetricly set in the groove.This action bars can match with the groove that is provided with on nut or the screw end face, thereby can be easily from axial operation.Action bars is detachable, to adapt to the nut and the screw of different model, size.

As preferably, be provided with the draw-in groove that is used for the socket action bars in the described groove, described draw-in groove is symmetrical arranged, and draw-in groove is the normal pitch setting.Described normal pitch is meant that the standard size with various nuts adapts.Described action bars can be connected in the draw-in groove, and is convenient fixing, and draw-in groove can be guarded against deviations owing to design in advance.

As preferably, described action bars is fixed on the headstock body by the chucking nut of both sides up and down.

As preferably, laterally be provided with scale on the described groove, thereby can make that the setting of action bars is more accurate.

The resulting screwdriver of the utility model, be exclusively used in axial rotary and establish nut or the screw that turns groove, thereby make that the operation of this class nut and screw is more simple and convenient and when sliding tooth, also can normally dismantle, avoid to adopt the chopping nut in the past or cut off the situation that screw rod is finished dismounting, more laborsaving convenience, and do not damage equipment.And when axial operation, do not take horizontal space, in less space, also can normally use.

The specific embodiment

The utility model will be further described in conjunction with the accompanying drawings below by embodiment.

Embodiment 1

As shown in Figure 3, the screwdriver that present embodiment is described, it mainly comprises driver bit 1, connecting rod 2 and handle 3, driver bit 1 is connected with handle 3 by connecting rod 2, described driver bit 1 is made up of headstock body 4 and two action bars 5, described headstock body 4 is provided with horizontal groove 8, in described action bars 5 detachably is symmetricly set on.Described action bars 5 is fixed on the headstock body 4 by the chucking nut 7 of both sides up and down, and action bars 5 is provided with the screw thread that matches, and can dismantle, and retightens after adjusting distance.On groove 8, laterally be provided with scale, thereby can make that the setting of action bars 5 is more accurate.

Embodiment 2

As shown in Figure 4, the screwdriver that present embodiment is described is provided with the draw-in groove 6 that is used for socket action bars 5 in the described as different from Example 1 groove 8, and described draw-in groove 6 is symmetrical arranged, and draw-in groove 6 is the normal pitch setting.Described normal pitch is meant that the standard size with various nuts adapts.
