Description

Adjustable drill holder barrel spanner

Technical field

The utility model relates to a kind of Wrench that loads and unloads clip, and particularly a kind of adjustable drill holder barrel spanner mainly is applicable to and builds the loading and unloading of protecting the frame clip.

Background technology

In present building constructions, all install and protect the safety that frame ensures the builder.Protecting frame is to connect into holistic with clip by many steel pipes, need a large amount of clips, it is very bothersome that this a large amount of clip is installed, labour intensity is also very big, and the instrument that loads and unloads clip at present and adopted is exactly common monkey wrench, this monkey wrench comprises handle, fixed jaw, movable jaw, adjusting screw(rod) constitutes, form a folder mouth between fixed jaw and the movable jaw, the size of the rotation adjustable clamp mouth by adjusting screw(rod), the shortcoming of this monkey wrench is: can not pull continuously, after every pair of clip turns an angle, need repeat chucking once, along with screwing of clip, otherwise that stops changes hands, that does not stop repeats same action, has not only reduced operating efficiency, but also makes workman's aerial work time lengthening, thereby cause some unsafe factors, in addition, this spanner has only two face chucking clips, and has only clip and spanner could use when a plane; The box spanner that uses though the chucking face is many, because sleeve is fixed, can not adapt to the clip of different size at present, and collet head is very easy to come off from hand lever the generation unsafe factor.

Summary of the invention

The purpose of this utility model is to provide a kind of and can not only clamps the clip multiaspect, is difficult for slippage, and internal diameter is variable, direction is adjustable, can be suitable for the clip of plurality of specifications, can disposablely tighten or unload after clip is clamped, can significantly improve installation effectiveness, reduce labor intensity, be exclusively used in to build and protect the adjustable drill holder barrel spanner that frame loads and unloads.

For reaching above purpose, the technical scheme that the utility model adopted is: this adjustable drill holder barrel spanner, constitute by handle and outer sleeve, handle is vertically fixed on the outer wall of outer sleeve, it is characterized in that in outer sleeve the suit sleeve that cogs, on gear sleeve, be provided with equidistant, vertical bolt die spaced teeth, establish the axial location groove at the outer surface of gear sleeve, between the bolt die spaced teeth, be respectively charged into bolt die, fixing retainer plate on the mouth wall of the bottom side of gear sleeve, be on the outer wall of outer sleeve upside again suit raises pitch circle at gear sleeve, and fixedly tighten circle, upper surface at adjusting ring is provided with snail shape screw thread, the basal surface ring shaped thread engagement of snail shape screw thread and bolt die, rotation by adjusting ring, make the bolt die clamping or unclamp the work package clip, the bolt die spaced teeth outside at gear sleeve fixedly tightens circle, to strengthen the intensity of bolt die spaced teeth, on the outer wall of outer sleeve, rotation direction adjuster in the fixed installation, the polarized plug of rotation direction adjuster is stuck in the axial location groove of gear sleeve, thereby the control outer sleeve is with respect to the counter-rotating of gear sleeve, just changeing or changeing simultaneously.The utility model is also implemented by following measure: described outer sleeve inwall is smooth arc surface, outer wall is formed at interval for two arcuation faces and two symmetrical plane surfaces of symmetry, screw is established at middle part at the arcuation face, the screw head of handle is rotated in the screw of arcuation on facing the wall and meditating fixing, handle can be established two, also can establish one, on the wall of the plane surface of a side, establish patchhole and bolt hole, the shell of rotation direction adjuster is rotated in by bolt on the wall that is fixed on plane surface in the bolt hole, and the polarized plug of rotation direction adjuster inserts in patchhole; Bolt die spaced teeth on the described gear sleeve can be established three, its width and interval radian thereof are 60 degree, adapt with the interval radian, bolt die is also established three, places between the bolt die spaced teeth of gear sleeve, and the width of bolt die is wide consistent with the rib of the building clip cap of minimum gauge, establish clip cap Ka Tai in bolt die spaced teeth base portion inboard, so that the clip cap can be stuck on the tram rapidly, the internal diameter of gear sleeve is 10-12mm, so that the clip screw rod stretches out; On the wall of three bolt die spaced teeth, be equipped with the screw of vertical axial, also establish corresponding three bolt die spaced teeth that have the vertical axial screw on tight loop, bolt die spaced teeth on the tight loop and the bolt die spaced teeth on the gear sleeve are fixed as one by corresponding bolts; Described bolt die, constitute by grip block and expansion plate, grip block and expansion plate vertical fixing are one, the inner surface of the grip block of bolt die is the plane, on inner surface, be provided with axial groove, clamp resistance to play a part to strengthen, establish ring shaped thread, stretch out the recess of expansion plate between the bolt die spaced teeth of tight loop at the basal surface of expansion plate; Described rotation direction adjuster, by shell, polarized plug, steering wheel, pull bar, the steering wheel rotation slot, spring, the steering wheel directive slide track constitutes, shell is fixed on the plane surface of outer sleeve with corresponding bolts, in polarized plug inserts and is stuck in axial location groove on the gear sleeve outer wall from inserting in the hole of outer sleeve, polarized plug simultaneously is the inclined-plane, other three is vertical plane, side outer sleeve gear sleeve reversing relatively towards the inclined-plane, under this kind state, continuable rotating spanner, realize the continuous work package clip of loading onto or unload, when inclined-plane during towards the axle center, then outer sleeve and gear sleeve are fixing changes in the same way, spring housing is on pull bar, one end seat of spring is on steering wheel, make not outwards slippage of polarized plug, on the inwall of shell, establish axial steering wheel directive slide track, on the edge of steering wheel, establish three spill mouths, the spill mouth is stuck on the steering wheel directive slide track, and the steering wheel rotation slot is established on top in the enclosure, when the pulling pull bar, when making steering wheel be raised in the steering wheel rotation slot, steering wheel is rotatable, and turning to of polarized plug realized in the position of conversion spill mouth; Described retainer plate can be fixed on the bottom side mouth wall of gear sleeve by steady pin.

The beneficial effects of the utility model are: compare with the monkey wrench of present use, compact conformation is reasonable, internal diameter is variable, rotation direction is adjustable, the clip that can adapt to plurality of specifications, the area of clamping clip is big, is difficult for slippage, use flexibly, once chucking can once be finished loading and unloading, improve operating efficiency greatly, reduced erector's labour intensity.
