Description

Universal wrench

Technical field

The utility model relates to a kind of spanner, refers in particular to the universal wrench that a kind of tommy bar can be done level angle adjustment and luffing angle adjustment.

Background technology

Spanner is the normal instrument that uses in industrial quarters or the family, commonly using spanner has a headstock, and is arranged at the drive division of headstock by the outward extending tommy bar of headstock,, this drive division is interlock screw piece (for example nut or bolt) directly, perhaps see through sleeve and the interlock screw piece, the user need only hold tommy bar, and in addition turn, screw piece can be unscrewed or locks.With existing wrench operated, usually be subject to dead angle or small space, so that its driving head can't be smoothly in conjunction with screw piece, in view of this, the novel M422451 rotary spanner of TaiWan, China structure is just arranged, M404088 rotary spanner structure, but the double (end) wrench that M244157 number 360 deg turns in length and breadth produces, it mainly makes the tool driving head do relative 360 degree luffing angle adjustment with tommy bar, only, this structure dispose still deficiency so that spanner at the dead angle or the small space operation have more flexibility, particularly, when spanner under the car of dead angle or small space during the dismounting screw piece, although its tommy bar can see through and adjust luffing angle, and links smoothly screw piece,, at tommy bar when rotating about driving head, it also can't drive the relatively large declinate of drive division turn one, causes the user must low-angle reciprocal drive tommy bar, and it is quite time-consuming and inconvenient in operation, the sense of getting half the result with twice the effort is often arranged, and this is failed to take into account part by the designer in fact.

In view of this, the design people is not for attaining perfect many disappearances and the inconvenience that causes in the design of above-mentioned spanner structure, and deeply design, and the active research improvement has a fling at and development and Design goes out this case.

The utility model content

The purpose of this utility model is to provide a kind of tommy bar can make the universal wrench that level angle adjustment and luffing angle are adjusted, and can reduce the number of times of reciprocal drive tommy bar, and it really has in operation and saves time and convenience.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of universal wrench, it includes:

One headstock, it has the parallel drive division of center line, the second hole, is provided with internal tooth in this second hole; One adaptor, it has the axostylus axostyle that can be coupled in the second hole, and is provided with the calibration piece that mates with internal tooth, and this axostylus axostyle endwisely slips along the second hole and drives calibration piece clutch internal tooth, and adaptor more maintains a branch of seat in the headstock outside, and is provided with the 4th hole; One control bar, it is axial moving between primary importance and the second place along the 4th hole; One spring, it is installed in the 4th hole, and this spring push control bar remains in primary importance; And a tommy bar, it sees through kingbolt and is articulated in the bundle seat, and this tommy bar is done the luffing angle adjustment take kingbolt as fulcrum.

Above-mentioned headstock also encircles recessed have the first buckle portion, the second buckle portion in the second hole, this second buckle portion is between the first buckle portion and interior between cog; Axostylus axostyle radially is concaved with the 3rd hole above the calibration piece, this 3rd hole is communicated with the 4th hole, and this 3rd hole is flexible for one first fixture block, and axostylus axostyle is sliding along the second hole axial limiting, actuates the first fixture block and switches in the first buckle portion or the second buckle portion; The control bar has first a recessed section forced to move, and when control bar during in the second place, first forced to move is shunk for the first fixture block, and when controlling bar in primary importance, first forced to move then promotes the first fixture block and be positioned the first buckle portion or the second buckle portion.

Bundle seat and axostylus axostyle are run through in the 4th hole of above-mentioned adaptor, and control aperture, the 4th hole and be big top and small bottom, and form a shoulder in inside; Control rod-shape and the 4th hole are symmetrical, form the larger head end of an external diameter at apical margin, and in control bar bottom one clasp that radially extends out is installed, between primary importance and the second place spacing movement axial along the 4th hole of control bar, this spring bottom butt shoulder, top pusher head distal process go out adaptor.

The center line of above-mentioned kingbolt is vertical and non-intersect with the second hole.

Above-mentioned bundle seat has the first symmetrical ear piece, the second ear piece, defines a branch of groove between this two ears piece, and the first ear piece is provided with a screw, then is provided with the hole relative with screw as for the second ear piece; Tommy bar one end has the pivot piece, and corresponding sliding being assigned in the bundle groove of this pivot piece, and be provided with the turn hole relative with screw sees through kingbolt and wears a hole of pulling, turns the hole and lock onto screw, locks this pivot piece in first and two ear pieces of bundle seat.

Above-mentioned bundle seat is provided with the 5th hole in a radial communication the 4th hole in the position of bundle groove bottom, the 5th hole and kingbolt center line are contour setting, and carry out expanding-contracting action for one second fixture block in the bundle groove; The control bar is concaved with the second section forced to move in the position in relative the 5th hole, when control bar during in the second place, second forced to move is shunk in the bundle groove for the second fixture block, and when control bar during in primary importance, second forced to move can promote the second fixture block and stretch in the bundle groove and locate; The pivot piece of tommy bar has the circular arc periphery, and be provided with some indexing troughs centered by kingbolt in pivot piece periphery, when the control bar is in the second place, its tommy bar is done the luffing angle adjustment, when the control bar is in primary importance, the indexing trough with relative that makes the second fixture block stretch agrees with, and tommy bar is fixed in this required luffing angle.
