Abstract
The invention relates to a sleeve. The sleeve is characterized by comprising a first connecting part (1) and a second connecting part (2), wherein the first connecting part (1) is provided with a first sleeve connector (12), the second connecting part (2) is provided with a second sleeve connector (22), and the first connecting part (1) and the second connecting part (2) are rotationally connected. Compared with the prior art, the sleeve disclosed by the invention has the advantages that two connecting parts connected mutually rotationally are arranged, and each connecting part is provided with the sleeve connector, thereby changing the force transmission direction according to actual demand when in use and being better applied in a complex maintenance and use environment.
Description
Technical field
The present invention relates to a kind of hand-operated tools, particularly relate to a kind of sleeve.
Background technology
In various pneumatic and hand-operated tools, often need to use sleeve, connect and the effect of the power of transmission to play.The sleeve connector of sleeve generally links to each other with joint, and the joint operated by rotary motion also comprises the screwdriver bit that is connected with securing member (such as screw, screw rod, nut etc.) on the connector on connector, is used for the fixedly screwdriver bit cover of screwdriver bit; The sleeve other end generally is connected with force arm, when external force is applied on the force arm, by sleeve, joint, screwdriver bit cover power is passed to screwdriver bit, and last screwdriver bit is applied to power on the securing member, is connected on the thing thereby securing member is fastened on.
Some pneumatic tool and hand-operated tools are in use, the environment more complicated, in the auto repair process, the space of leaving operating personnel and maintenance tool for can be restricted, and existing sleeve can not change the direction of transfer of power, therefore uses to have inconvenient defective.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of sleeve that can change the direction of transfer of power for above-mentioned prior art.
The present invention solves the problems of the technologies described above the technical scheme that adopts: this sleeve, it is characterized in that: comprise the first connecting portion with first sleeve connector, with the second connecting portion with second sleeve connector, be rotationally connected between described the first connecting portion and the second connecting portion.
The axial place of described the first connecting portion one side is provided with accommodating hole, the second connecting portion is at the adapter that is provided with of a corresponding side, described adapter rotates and is arranged in the described accommodating hole, be provided with in the described accommodating hole first end offset with adapter or link to each other, elastic supporting member for supporting optical member that the second end and described accommodating hole inwall offset or link to each other.Such the first connecting portion and the second connecting portion have had the support of elastic supporting member for supporting optical member in use, can not rock.
Preferably, the first end of described elastic supporting member for supporting optical member is welded on the described adapter.
Described adapter is spherical in shape to be good.
Compared with prior art, the invention has the advantages that: two connecting portions that mutually are rotationally connected are set, the sleeve connector all is set on each connecting portion, so that sleeve provided by the invention can change the direction of transfer of power in use according to actual needs, in the maintenance and use environment of circumstance complication, can be well used.
