Technical field
The present invention relates to auto parts and components manufacture fields, assemble the hand-held of anti-lost buckle for screw more particularly to a kind of
Tool.
Background technique
The part being related on one automobile is ten hundreds of, and wherein fastener (screw, nut) occupies half of the country, in order to drop
The assembly line fussy degree of low main engine plants, also for reducing neglected loading, wrongly installed risk, the selection of most of main engine plants allows components
Fastener is dispensed on the part of its supply of material by supplier, also just essentially uses the anti-lost buckle of screw in this way.Often
The technique of rule is manually to cover anti-lost buckle on screw, and such assembly method efficiency is lower, and assembling quality is not easily-controllable
System, easily causes and does over again, anti-lost buckle is scrapped.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of handheld tool for assembling anti-lost buckle for screw, it can
It realizes and the quick rank of anti-lost buckle is taken, quickly by anti-lost snap-fitted on screw, structure is simple, easy to use.
The technical solution adopted by the present invention to solve the technical problems is: a kind of to assemble the hand-held of anti-lost buckle for screw
Tool, it includes sleeve, the handle fixed with sleeve rear end, the clamping jaw being threaded through in sleeve and handle；Before the clamping jaw includes
The slide bar of the clamping jaw head and rear side for holding in the mouth the internal expansion type for taking anti-lost buckle of side；The front end of the clamping jaw head is prominent in sleeve
Outside is additionally provided with pawl return spring in the front-back direction between slide bar and handle.
The clamping jaw title takes alignment screw after anti-lost buckle, is pushed by handle to screw, and clamping jaw head is opposite to retract set
In cylinder, sleeve is by anti-lost buckle pushing sleeve in the designated position of screw, and after sleeve pulls away screw, pawl return spring pushes clamping jaw,
Make the nose heave new protrusion of clamping jaw outside sleeve.
Lock groove is additionally provided between the clamping jaw head and slide bar；The side of the sleeve is in position corresponding with lock groove
It is provided with control button, is additionally provided with push-button reset spring between the bottom end and sleeve of control button；The control button and lock
Only slot cooperates, and cannot retract in sleeve for controlling clamping jaw head when rank takes anti-lost buckle.
The control button is provided with lockhole, and the diameter of lockhole is greater than the diameter of clamping jaw head；Rank is when taking, control button not by
It presses, is stuck in lock groove on the downside of the lockhole of control button, the axial freedom of clamping jaw is fixed；When assembly, control button
In down state, clamping jaw head backs through lockhole under the action of handle presses, and moves back clamping jaw relative sleeve and handle
It is dynamic.
The diameter that the diameter of the lockhole of the control button is less than slide bar forms the front limit of clamping jaw for blocking slide bar.
Beneficial effects of the present invention: a kind of handheld tool assembling anti-lost buckle for screw of the invention passes through clamping jaw
It is held in the mouth by way of internal expanding and takes anti-lost buckle, after alignment screw, pressing control knob unlocks clamping jaw, sleeve pushes anti-lost card
Retaining ring is in screw designated position, and after taking-up, clamping jaw resets under the action of pawl return spring；It realizes to the quick of anti-lost buckle
Rank takes, quickly by anti-lost snap-fitted on screw, and structure is simple, easy to use.
