Background technique

Tool involved in workshop or repair shop, such as pickup, examining watching mirror, need to install on it a knuckle with The use of different angle, different directions is reached, to meet the application under different scenes.

Publication No.: the utility model patent of 208305029 U of CN discloses a kind of magnetic pick-up device.The magnetism is picked up Device: including magnetic pickup head, telescopic rod, handle, head, one end of the magnetism pickup head and the telescopic rod passes through institute Head connection is stated, the magnetism pickup head includes shell, magnet, LED, and the magnet, LED are disposed in the housing, The shell, which is equipped with, leads to extraneous opening, and the magnet is installed in the shell, and is located at the opening, the LED The light of sending can pass through the opening, and the other end of the telescopic rod connects the handle.Wherein head includes the first folder Plate, second clamping plate, the first clamping plate, second clamping plate are arranged in parallel and pass through screw, are bolted；Head is additionally provided with One rotary shaft, the second rotary shaft, first rotary shaft, the second rotary shaft are set between the first clamping plate, second clamping plate, institute It states the first connecting ball head and is movably installed on first rotary shaft, the second connecting ball head of the telescopic rod is movably pacified Loaded on second rotary shaft.

The head used in a kind of above-mentioned magnetic pick-up device is to rotate section, although which enables to Magnetic tip rotation, but its structure is relatively complicated, installation is inconvenient, considerably increases the production installation cost of pickup.

Summary of the invention

In view of the problems of the existing technology, it is an object of the invention to design to provide a kind of technical solution of knuckle.

The knuckle, it is characterised in that inscribed A and inscribed B, the inscribed A are equipped with including sleeve, in the sleeve Be equipped with elastic component between inscribed B, under the elastic reaction of elastic component, the inscribed A limit on the inside of sleeve one end and It can be rotated relative to sleeve, while the inscribed B limit can rotate on the inside of sleeve one end and relative to sleeve.

The knuckle, it is characterised in that the sleeve includes first sleeve and second sleeve interconnected, described It is equipped with inscribed A in first sleeve, inscribed B is equipped in the second sleeve, under the elastic reaction of elastic component, the inscribed A limit Position is in first sleeve far from can rotate on the inside of second sleeve one end and relative to first sleeve, while the inscribed B is limited and existed Second sleeve is far from first sleeve one end inside and can rotate relative to second sleeve.

The knuckle, it is characterised in that the elastic component is spring.

The knuckle, it is characterised in that the inscribed A includes the rotation seat A and stretching sleeve limited in sleeve Interconnecting piece A, the inscribed B include the interconnecting piece B for limiting rotation seat B in sleeve and stretching out sleeve.

The knuckle, it is characterised in that the rotation seat A is contacted with sleeve ends inside cord, and contact line is circle Shape, the rotation seat B are contacted with sleeve ends inside cord, and contact line is circle.

The knuckle, it is characterised in that the rotation seat A and rotation seat B is spherical or hemispherical dome structure, described Rotation seat A and rotation seat B package is partly wrapped in sleeve ends.

Above-mentioned knuckle, structure is simple, and design rationally, has the advantages that compared with prior art

1) entire knuckle is only made of sleeve, inscribed A, inscribed four components of B and spring, and structure is simple, improves production efficiency, Reduce manufacturing cost；

2) sleeve is connected using first sleeve with second sleeve, and A and inscribed B is inscribed and is limited using elastic component, easy for assemble or unload, It need to will only be screwed in inscribed A, inscribed B and elastic component merging first sleeve and second sleeve when installation；

3) A and inscribed B being inscribed can rotate relative to sleeve, realize steering.

In figure: 1- is external；A is inscribed in 2-；201- rotation seat A；202- interconnecting piece A；3- elastic component；4- first sleeve；5- Two sleeves；B is inscribed in 6-；601- rotation seat B；602- interconnecting piece B.

Specific embodiment

The present invention is further illustrated below in conjunction with Figure of description.

As illustrated in fig. 1 and 2, knuckle includes sleeve, and inscribed A2 and inscribed B6 is equipped in sleeve, be inscribed A2 and inscribed B6 it Between be equipped with elastic component 3, under the elastic reaction of elastic component 3, A2 limit is inscribed on the inside of sleeve one end and can be relative to Sleeve rotation, while inscribed B6 limit can rotate on the inside of sleeve one end and relative to sleeve.Inscribed A2 includes that limit is covering Rotation seat A201 in cylinder and the interconnecting piece A202, inscribed B6 for stretching out sleeve include limit rotation seat B601 in sleeve with And stretch out the interconnecting piece B602 of sleeve.Wherein rotation seat A201 and rotation seat B601 realizes the rotation of inscribed A2 and inscribed B6, even Socket part A202 and interconnecting piece B602 realizes the pickup head of inscribed A2 and inscribed B6 and tool (such as pickup), handle, connects machine fastly Structure connection, the interconnecting piece A202 of the inscribed A2 shown as shown in figure 1 are connected to external 1.

Sleeve includes first sleeve 4 and second sleeve 5 interconnected, and first sleeve 4 and second sleeve 5 can use spiral shell Line connection, can also be using connection types such as snappings.The lines such as the settable annular knurl of first sleeve 4 and 5 outer surface of second sleeve, one Aspect reaches aesthetic effect, antiskid effect when on the other hand reaching installation.

Elastic component 3 is preferably spring, and both ends of the spring cooperation cooperates with inscribed A2 and inscribed B6 respectively, in the elasticity of spring 3 Under effect, by inscribed A2 and inscribed B6 limit on the inside of sleeve ends.

It is equipped with when sleeve is made of first sleeve 4 and second sleeve 5, in first sleeve 4 and A2 is inscribed, in second sleeve 5 Equipped with inscribed B6, under the elastic reaction of elastic component 3, the inscribed A2 limit is in first sleeve 4 far from 5 one end of second sleeve Side and can be rotated relative to first sleeve 4, at the same inscribed B6 limit second sleeve 5 far from the inside of 4 one end of first sleeve and It can be rotated relative to second sleeve 5.

Rotation between inscribed A2, inscribed B6 and sleeve is by being realized with flowering structure: rotation seat A201 and sleeve (the One sleeve 4) contact of tip inside line, and contact line is circle, rotation seat B601 connects with sleeve (second sleeve 5) tip inside line Touching, and contact line is circle, is contacted by the distinct line between rotation seat A201 and rotation seat B601 and sleeve, realizes its turn It is dynamic.As preferred structure, rotation seat A201 and rotation seat B601 are spherical or hemispherical dome structure, rotation seat A201 and rotation seat B601 is wrapped up or is partly wrapped in sleeve ends, realizes its rotation.As shown in figure 3, the rotation between inscribed A2, inscribed B6 and sleeve Schematic diagram.

The present invention is not limited to be applied to pickup, examining watching mirror, can also use using the steering with other tools.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution The range of scheme.
