In order to achieve this end, the technical solution adopted in the utility model is: the T-shaped box spanner of a kind of adjustable connecting-rod length self-forming, comprises transversal stretching connecting rod, T-shaped tetragonal body slide block, spill block node, bias elastic ball, longitudinal extension connecting rod, collet head, sleeve die cavity, polarizing slot, one group of telescopic pin, elastic component, fixed support, chamfering.The working face of the die cavity inside of described shrinking connecting-rod is provided with spill block node, a working face of T-shaped tetragonal body slide block is provided with bias elastic ball, three tetragonal body slide blocks are fixedly connected with and form T-shaped frame, the working face of the die cavity inside of longitudinal extension connecting rod is also provided with spill block node, longitudinal adjustable link is fixedly connected with collet head, polarizing slot is provided with in the middle part of collet head die cavity, fixed support is provided with the hole of aligned transfer, one group of telescopic pin is closely discharged at collet head die cavity, one end of each pin terminates in the openend near described die cavity, the effect that each pin all can overcome elastic component is retracted separately in described die cavity.
The end of two transversal stretching connecting rods is provided with chamfering, tell shrinking connecting-rod die cavity interior shape be tetragonal body, the working face of die cavity inside is provided with a series of spill block node, and the end of T-shaped tetragonal body slide block is provided with chamfering.
Each telescopic pin close to tell chamber openend have the second larger diameter part, elastic component of telling acts between told fixed support and this second larger diameter portion divide.
Telescopic pin of telling is roughly circular cross-section, and sleeve die cavity of telling is inscribed hexagon cross section.
Tell sleeve die cavity inwall be provided with the parallel groove distributed with telescopic pin.
Adjust the length of transversal stretching connecting rod during use according to required power when dismounting or fastenings, also can be adjusted the length of longitudinal direction by longitudinal extension connecting rod.Also can be used for dismounting or more fastening irregular bolt or nuts etc. in a word, can reach convenient and swift.
Compared with existing T-shaped box spanner, the beneficial effects of the utility model are: the length setting transversal stretching connecting rod and longitudinal extension connecting rod can regulate, and make workmen use easily, convenient and swift.Also set self-forming T-shaped collet head, can to dismantle parts such as the bolt of some different sizes, nut, wing nuts or fastening.
