The specific embodiment
Referring to figs. 1 through Fig. 5, the detachable torque wrench embodiment of the utility model is described further.
A kind of detachable torque wrench, comprise cylindrical can assembled handle 1, matrix 2 and hexagonal bolt sleeve 3 that T-shaped structure arranges, described bolt sleeve 3 is positioned at matrix 2 middle parts, the two ends of described matrix 2 are horizontal and vertical be respectively equipped with can with the first blind hole 4 and second blind hole 5 of can assembled handle 1 pegging graft and coordinating, the second blind hole 5 communicates up and down longitudinally, described matrix 2 comprises the contiguous block 6 being fixedly connected with bolt sleeve 3 and the hinge bar 7 that is hinged on contiguous block 6 two ends, contiguous block 6 two ends are respectively equipped with mounting groove, on two hinge bars 7, be equipped with respectively rotating shaft, two hinge bars 7 are arranged in mounting groove by rotating shaft respectively rotationally, between described hinge bar 7 and contiguous block 6, be provided with limit switch 8, described limit switch 8 comprise respectively can with the inserted link 81 of two hinge bar 7 clampings, described two inserted links 81 are located on contiguous block 6 slidably, on described contiguous block 6, be respectively equipped with the through hole 82 sliding for inserted link 81, described two inserted link 81 one end all extend to outside contiguous block 6 and between its both ends, are provided with linkage board 83, between described linkage board 83 and contiguous block 6, be provided with back-moving spring 84, linkage board 83 is provided with groove, back-moving spring 84 is fixedly mounted in the groove on contiguous block 6, when hinge bar 7 is vertical with contiguous block 6, described hinge bar 7 is provided with the first draw-in groove 85 with inserted link 81 clampings, when described hinge bar 7 is parallel with contiguous block 6, described hinge bar 7 is provided with the second draw-in groove 86 with inserted link 81 clampings.
By adopting technique scheme, if the words that horizontal space is restricted in spanner wrenching bolt, linkage board 83 can be pulled outward spins off respectively two inserted links 81 from the second draw-in groove 86, and then rotating hinge extension bar 7 makes it vertical with contiguous block 6, inserted link 81 can automatically snap onto in the first draw-in groove 85 under the effect of back-moving spring 84, and whole like this matrix 2 just greatly reduces in horizontal taking up room; The hinge bar 7 at two ends rotates to vertical with contiguous block 6 time, make whole matrix 2 greatly elongated on vertically, so just can remove easily to rotate the bolt in some deep trouths, whole spanner can change hinge bar 7 and position that can assembled handle 1 according to operating space, makes the more difficult restriction that is subject to operating space of handle; Two hinge bars 7 rotate to parallel with contiguous block 6 time, can make like this moment become large, make spanner more laborsaving when pulling; Two hinge bars 7 can stably fix with contiguous block 6 by two inserted links 81, and in needs rotating hinge extension bar 7, easy to operate, as long as pull linkage board 83 just passable, simple in structure being easy to of whole limit switch 8 manufactured; Can directly be inserted in the first blind hole 4 and the second blind hole 5 by assembled handle 1, and can on the sidewall of assembled handle 1, be provided with flange, flange is supported the end of hinge bar 7, wrench is when pulling like this, can assembled handle 1 and the place of hinge bar 7 junctions not fragile, be provided with after linkage board 83, as long as just can drive two inserted links 81 to move after pulling linkage board 83, simple and convenient.
Described arbitrary hinge bar 7 is provided with clamping block 9, and described another hinged block is provided with projection 10, described projection 10 be provided with can with the buckling groove 11 of clamping block 9 rotary fastenings.
By adopting technique scheme, when two hinge bars 7 turn to respectively vertical with contiguous block 6 time, clamping block 9 snaps onto fastening, can make like this two hinge bars 7 more stable regularly, make spanner when torsion is pulled, the place that hinge bar 7 is connected with contiguous block 6 is difficult for turning round bad.
On described bolt sleeve 3 inwalls, be fitted with some hexagonal lamellar bodies 12, in described bolt sleeve 3, be provided with elastomer block 13, described lamellar body 12 the inners are all connected with contiguous block 6 by elastomer block 13.
By adopting technique scheme, when bolt sleeve 3 is set on bolt, bolt can be compressing into top than its little lamellar body 12, and large lamellar body 12 is understood the fastening bolt that entangles, and so just can pull the bolt of different size dimensions.
Described clamping block 9 sidewalls are provided with the elastic bumps 14 of circular arc, be provided with and can cave in 15 with the circular arc of elastic bumps 14 clampings in described buckling groove 11.
By adopting technique scheme, clamping block 9 sidewalls are provided with the elastic bumps 14 of circular arc, in buckling groove 11, be provided with and can cave in 15 with the circular arc of elastic bumps 14 clampings, after clamping block 9 and buckling groove 11 clampings, elastic bumps 14 snaps onto in circular arc depression 15 again and makes clamping block 9 and projection 10 fixing-stables like this.
The outside of described linkage board 83 is provided with and helps pulling block 16, described in help pulling block 16 for the setting of T shape.
By adopting technique scheme, help pulling block 16 for the setting of T shape, when needs pull linkage board 83, as long as help on pulling block 16 by finger is anchored to, can facilitate like this people to exert all one's strength, thereby can pull linkage board 83 more conveniently.
