Abstract

The utility model belongs to the technical field of hand-operated tools, in particular relates to a quick clamping adjustable wrench. The wrench is characterized in that a supporting shaft arranged at the lower part of a worm gear is also provided with a pressing spring; a fixing clamp jaw body, on which a hinge shaft is arranged, is connected with a handle; the fixing clamp jaw body is positioned at the lower part of a core-shaped body arranged in a handle cavity and provided with a cambered guide groove, in which a guide post is arranged; two ends of the guide posts are fixed on the handle; an offsetting spring is arranged between the inner end of the cambered guide groove and the guide posts; a limit post of the warm gear is arranged oppositely to the handle and positioned at the place of a pressing groove in a communication groove; a lock device is also arranged between an adjustable clamp jaw body and the handle. Because of the structure, the adjustable wrench has the advantages that the workpieces can be avoided to be damaged and the work efficiency is high.

Description

Fast clamping adjustable wrench

Technical field:

The utility model belongs to the hand-operated tools technical field, is specifically related to a kind of fast clamping adjustable wrench.

Background technology:

Existing adjustable wrench during use, according to the appearance and size of workpiece, is regulated the open size of jaw by worm gear and tooth bar earlier, insert workpiece again, pull spanner clockwise, need transfer to spanner to insert again when workpiece turns over certain angle, its shortcoming is fragile workpiece, inefficiency.

Summary of the invention:

The purpose of this utility model provides a kind ofly can avoid defective work piece, the fast clamping adjustable wrench of high efficiency.

The technical solution of the utility model is: a kind of fast clamping adjustable wrench, form by regular jaw body, moving jaw body and handle; The lead of moving jaw body is positioned at the slideway on the regular jaw body, establishes tooth bar on the lead; On the regular jaw body, establish groove with the lead correspondence position; Worm gear is installed in the groove by back shaft, and the tooth bar that is provided with lead engagement; It is characterized in that: also be provided with stage clip on the back shaft of worm gear downside; Establish hinge on the regular jaw body and link to each other with handle, the regular jaw body is positioned on the bullet downside of handle cavity establishes arc guide groove; Establish lead in the arc guide groove, the lead two ends are fixed on the handle, establish return spring between arc guide groove the inner and lead; Also establish the spacing cylinder of worm gear on the handle correspondence position, the limited post body is positioned at the stage clip place of groove; Between moving jaw body and handle, also establish locking device.Wherein, described locking device is by the chute on the handle, establishes lock on the chute and cooperates composition with the seam that the end of regular jaw body is provided with; Be provided with compression spring and limited block in the chute in the lateral aperture, limited block and lock cylindrical join.

Owing to adopt technique scheme, during use, lock and seam are opened, and regulate worm gear and tooth bar position, and jaw is fixed on the working face of workpiece, clockwise rotate handle, when workpiece turns to certain angle with spanner, rotate counterclockwise handle, under the corner angle effect on the workpiece, the spacing cylinder of worm gear is deviate from groove, the jaw body that promotes to live outwards moves, and the rack drives worm gear also outwards moves, and jaw goes to the next working face on the workpiece automatically, under the effect of back-moving spring and stage clip, spacing cylinder and moving jaw body reset, and finish a working cycles, repeat above-mentioned action, when workpiece during near the moment of torsion that requires, lock on the handle is pushed in the seam of regular jaw body, handle and regular jaw body are connected, and workpiece can be tightened, thereby have and to avoid defective work piece, the advantage of high efficiency.

Description of drawings:

Come the technical solution of the utility model is described further below in conjunction with the drawings and specific embodiments.

Fig. 1 is the utility model structural representation.

View when Fig. 2 deviates from for the spacing cylinder of the utility model.

The specific embodiment:

With reference to figure 1 and Fig. 2, a kind of fast clamping adjustable wrench is made up of regular jaw body 1, moving jaw body 2 and handle 3; The lead of moving jaw body 2 is positioned at the slideway on the regular jaw body 1, establishes tooth bar 6 on the lead; On regular jaw body 1, establish groove 4 with the lead correspondence position; Worm gear 5 is installed in the groove 4 by back shaft 7, and tooth bar 6 engagements that are provided with lead; Also be provided with stage clip 8 on the back shaft 7 of worm gear 5 downsides; Establish hinge on the regular jaw body 1 and link to each other with handle 3, regular jaw body 1 is positioned on the bullet downside of handle 3 cavitys establishes arc guide groove 10; Establish lead 12 in the arc guide groove 10, lead 12 two ends are fixed on the handle 3, establish return spring 11 between arc guide groove 10 the inners and lead 12; Also establish the spacing cylinder 9 of worm gear 5 on handle 3 correspondence positions, spacing cylinder 9 is positioned at stage clip 8 places of groove 4; Between moving jaw body 1 and handle 3, also establish locking device.Described locking device is by the chute on the handle 3 13, establishes lock 17 on the chute 13 and cooperates composition with the seam 14 that the end of regular jaw body 1 is provided with; Be provided with compression spring 15 and limited block 16 in the chute 13 in the lateral aperture, limited block 16 joins with lock 17 cylindricals.
