Description

A kind of fast cross wrench

Technical field

This utility model belongs to hardware & tools field, is specifically related to a kind of fast demountable bolt cross like spanner.

Background technology

Tradition cross like spanner is formed by two cylinder crosses are affixed, and every cylinder links into an integrated entity with end sleeve, and its shortcoming is that range of application is less, takies memory space big, and spanner screw-down torque can not change, and makes troubles to accumulating；Tradition cross like spanner sleeve and shank one be also comparatively inconvenience when demounting bolt.Such as, patent CN101579846A discloses a kind of speed and unloads cross like spanner, two cylinder decomposable asymmetric choice net, but as broad as long with tradition cross like spanner essence, can not improve bolt disassembly speed.

Summary of the invention

For prior art problem, this utility model provides a kind of simple in construction, applied range, the cross like spanner of fast demountable bolt.Described technical scheme is as follows:

A kind of fast cross wrench includes trigger piece, rotates lever, cross axle, extension bar；Described cross axle comprises relatively long handle axle and three socket joint holes, and described rotation lever is arranged on described Handle axis by deep groove ball bearing, and both can relatively rotate；Described cross axle and described trigger piece are arranged on its both sides by described socket joint hole, and described sleeve is connected with described cross axle by described extension bar, adopt socket joint to connect each other.

This utility model have employed has the fast cross wrench rotating lever, and more traditional cross like spanner is compared and had the advantage that

1, rotate lever to relatively rotate with cross axle and end sleeve thereof, it is possible to improve bolt sky and twist speed, decrease bolt disassembly sky and twist the time, improve work efficiency；

2, the disassembled connection between cross axle handle with trigger piece, extension bar all adopts typical socket joint to connect, and convenient wrench is disassembled, accumulating, fast changeable trigger piece and sleeve, increases the scope of application and the convenience of spanner.

Detailed description of the invention

Referring to figs. 1 through Fig. 2, the utility model relates to a kind of fast cross wrench, its preferably embodiment be:

A kind of fast cross wrench provided by the utility model, including trigger piece 1, rotates lever 2, cross axle 3, extension bar 4；Cross axle 3 comprises relatively long handle axle the 34, first trigger piece socket joint square hole 31, extension bar socket joint square hole 32 and a second trigger piece socket joint square hole 33；Rotating lever 2 and be arranged in Handle axis 34 by deep groove ball bearing, both can relatively rotate；Cross axle 3 is packed in its both sides by first the 31, second trigger piece socket joint hole, trigger piece socket joint hole 33 with disassembled form with trigger piece 1, and sleeve 5 is connected with cross axle 3 by extension bar 4, adopts socket joint to connect each other.

Operation principle of the present utility model is: first passes through trigger piece 1 during Bolt dismantling and unscrews, and operator can hold rotation lever 2 thereafter, stirs trigger piece 1 and quickly realizes idle running, is screwed out rapidly by bolt, improve efficiency and the convenience of bolt disassembly.
