Utility model content
To overcome above-mentioned deficiency of the prior art, the purpose of this utility model is to provide a kind of locking device, and it is tied Structure is simple, reasonable in design, makes the replacing of rotating the needle convenient and swift, saves the time, improves sander operating efficiency.
A kind of locking device, including connector one, the end of the connector one match connection, the company with connector two The end of joint two connects clamp, is provided with rotating the needle in the clamp, clamp may tighten or loosen rotating the needle;The outer cover of connector two One is connect to assure, it is described assure in be provided with spring, the spring one end abuts with connector two, the other end with assure in the middle part of abut; The top of assuring matches connection with copper sheathing one, and on clutch shaft bearing, the clutch shaft bearing is connected the copper sheathing one with outer tube, The outer pipe bottom is connected with second bearing, and the second bearing is connected with copper sheathing two, the lower end Joining clasp of copper sheathing two, is led to Cross to make to assure in upper and lower part setting copper sheathing one, the copper sheathing two assured and can reduce friction, height rotation.
Further, the clamp end is in horn-like clamping part, and there are 3, which to split groove, on the clamping part surface makes folder Hold the force-applied after-contraction in portion, clamp is moved backward therewith because spring pushes up connector two backward under normality, clamping part just with bag Pipe end is tightly sleeved together so that clamping part, which shrinks, clamps rotating the needle;When connector two is moved along, clamp moves forward therewith, The clamping part of clamp with assure separate after be able to unclamp rotating the needle.
Further, the afterbody of the connector one is the first Access Division, and the first clamping cross section is " ten " word Shape, the front end of connector one have cylindrical groove, and the cylindrical groove bottom is cross recess.
Further, the connector two includes integrally formed post portion one, post portion two, post portion three, cross Access Division, institute State post portion one to be tightly sleeved with clamp, the post portion two is with assuring socket, after post portion three inserts the cylindrical groove of connector one Cross Access Division can be made to match clamping with cross recess.
Further, described to assure with cavity one, cavity two, the spring is in cavity one, spring one end and company The post portion two of joint abuts, and the other end abuts with the bottom of cavity one.
Operation principle:In use, because the spring in assuring imposes elastic force backward to connector two, being moved after connector makes With clamp also with moving afterwards until the clamping part of clamp blocks completely with assuring, now the clamping part of clamp, which shrinks, clamps rotating the needle; When making connector two travel forward in the presence of external force, clamp also moves forward therewith, and the clamping part of clamp drives rotating the needle reach, by It is able to recover open configuration after clamping part departs from and assured, rotating the needle is also clamped portion and unclamped.
The utility model is simple in construction, reasonable in design, and the replacing of rotating the needle is convenient and swift, saves the time, improves sander Operating efficiency.
Brief description of the drawings
The accompanying drawing used required for utility model will be briefly described below, it should be apparent that, in describing below Accompanying drawing is only preferred embodiment of the present utility model, for those of ordinary skill in the art, is not paying creative labor On the premise of dynamic, other accompanying drawings can also be obtained according to this accompanying drawing.
