Abstract

The invention belongs to the field of hardware tools, and particularly relates to a cross wrench used for fast disassembling and assembling nuts. The cross wrench comprises a wrench handle 1, a rotating grabbing handle 2, a cross shaft 3 and a connection rod 4. The cross shaft 3 comprises a long handle shaft 34, a first wrench handle socket square hole 31, a connection rod socket square hole 32 and a second wrench handle socket square hole 33. The rotating grabbing handle is installed on the handle shaft through a deep groove ball bearing, the bolt idle screwing speed can be increased, the bolt disassembly and assembly idle screwing time is shortened, work efficiency is improved, detachable connection among a cross shaft handle, the wrench handle and the connection rod is typical socket connection, the wrench is convenient to disassemble, store and transport, the wrench handle and a sleeve can be fast replaced, the application range of the wrench is widened, and convenience of the wrench is improved.

Description

A kind of fast cross wrench

Technical field

The invention belongs to hardware & tools field, be specifically related to a kind of fast demountable bolt cross like spanner.

Background technology

Tradition cross like spanner forms by two cylinder crosses are affixed, and often prop up cylinder with end sleeve links into an integrated entity, its shortcoming is that range of application is less, and take memory space greatly, spanner screw-down torque can not change, and makes troubles to accumulating; Tradition cross like spanner sleeve and handle bar 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 traditional cross like spanner essence, can not improve bolt disassembly speed.

Summary of the invention

For prior art problem, the invention provides a kind of structure simple, applied range, the cross like spanner of fast demountable bolt.Described technical scheme is as follows:

A kind of fast cross wrench comprises trigger piece, rotates lever, cross axle, extension bar; Described cross axle comprises comparatively 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.

Present invention employs the fast cross wrench having and rotate lever, more traditional cross like spanner is compared and is had the following advantages:

1, rotate lever and cross axle and end sleeve thereof to relatively rotate, bolt sky can be improved and twist speed, decrease bolt disassembly sky and twist the time, improve operating efficiency;

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

In figure: 1, trigger piece; 2, lever is rotated; 3, cross axle; 4, extension bar; 5, sleeve; 31, the first trigger piece socket joint square hole; 32, extension bar socket joint square hole; 33, the second trigger piece socket joint square hole; 34, Handle axis

Detailed description of the invention

Referring to figs. 1 through Fig. 2, what the present invention relates to is a kind of fast cross wrench, its preferably embodiment be:

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

Operation principle of the present invention is: first unscrewed by trigger piece 1 during Bolt dismantling, and operating personnel can hold and rotate lever 2 thereafter, stirs trigger piece 1 and realizes idle running fast, screwed out rapidly by bolt, improve efficiency and the convenience of bolt disassembly.
