Embodiment
It should be appreciated that specific embodiment described herein is not used to limit this only to explain the utility model
Utility model.
With reference to Fig. 1, the present embodiment provides a kind of clamp spring of screw nail locking mechanism, including flexible arc-shaped card
Spring body and the opening being arranged on clamp spring body；In use, the gathering of the spring body at opening both ends is realized on screw nail locking mechanism
Positioning element closure；The dismounting of the positioning element on screw nail locking mechanism is realized in the separation of the spring body at opening both ends.
With reference to Fig. 2 to Fig. 4, the concrete structure of the screw nail locking mechanism described in the present embodiment is：Including 3 He of telescopic sleeve
Screw chuck 4, telescopic sleeve 3 are socketed in the outside of screw chuck 4.Wherein, telescopic sleeve 3 include jacket casing 31, spring 32,
32 snap ring 33 of spring and cover 34；Screw chuck 4 includes shank 41 and the clamping part 42 for clamping screw 5, and shank 41, which divides, is
Top and lower part, and the lower part of shank 41 is connected with clamping part 42.
Above-mentioned spring 32 is socketed in the lower part foreign side of shank 41, forms an elastic buffer member.It is provided with cover 34
The mutually socket of through hole, cover 34 and jacket casing 31 forms a cavity, which includes three parts from bottom to top, and Part I is
Lower cavity 351 for the lower part for accommodating the shank 41 for being socketed with spring 32；Part II is the top for accommodating shank 41
Upper plenum 352；Part III is the cushion chamber 353 to stretch upwards for shank 41.32 snap ring 33 of spring passes through pin 43
It is fixed on screw chuck 2, so as to block spring 32.Cover 34 and jacket casing 31 are assembled together, and spring 32 and spring 32 are blocked
Ring 33 is limited to the intracavitary of jacket casing 31, and screw clamp set 2 can be made to have certain elastic space, play the role of elastic buffer.
The shape of the cavity of the present embodiment is convex, its size shape matches with elastic buffer member., will during assembling
After shank 41 passes through 32 snap ring 33 of cover 34 and spring, jacket casing 31 is finally arranged by 32 sets of lower parts for being set to shank 41 of spring
In the outside of shank 41, assembling is realized.
When the clamping part 42 of screw chuck 2 holds screw 5 and is rotating the tooth hole for touching workpiece, screw and corresponding
Tooth hole screw terminal may be inconsistent, and the screw thread of screw 5, which can be rotated to, consistent with workpiece tooth hole screw terminal could normally make screw thread
Engagement, screw terminal do not have corresponding screw 5 to continue to rotate, are normally engaged again until finding screw terminal.Whole screw lock machine
Structure continue is declining, and screw 5 also without screw in tooth hole when, spring 32 compression absorbs this partial depth, alleviate to tooth line
Impact, avoid the destruction to tooth hole.The screw nail locking mechanism of the present embodiment is when reaching screw 5 that torque settings tighten just
Rotation is stopped, spring 32 can also absorb certain depth, buffer the pressure that whole screw fixture continues to decline, avoid hole
Mouthful deformation, flash, screw difference in height, torsion are inconsistent etc. bad.
As shown in figure 5, clamping part has further included holding holes 421 and positioning element, which is arranged on holding holes 421
Hole edge, and an annular slot 425 is further opened with the periphery of positioning element position.Positioning element include location hole 422,
Positioning bead 423 and retaining spring 424.Wherein, retaining spring 424 radially snaps fit onto positioning bead 423 toward 422 direction of location hole
In location hole 422, the clamp spring of the present embodiment is snapped fit onto in card slot 425, and retaining spring 424 and positioning bead 423 are blocked and positioned
In hole 422.Positioning bead 423 can in location hole 422 resilient movement.In use, the screw for offering screw channel is transferred to clamping
In hole 421, positioning bead 423 is stuck in screw channel, the positioning of screw.Screw positioning bead 423 will under 424 thrust of retaining spring
Screw is stuck in holding holes 421, and after the screw hole contraposition on screw and workpiece is tightened, screw nail locking mechanism moves up, positioning bead
423 rebounds so that screw chuck and screw separation, complete the assembling of workpiece screw.This positioning method accurate positioning, ensure that screw
All the time it is consistent with the direction of screw hole, easy to smoothly lock, it is crooked to avoid screw.
Using process, positioning bead 423 and retaining spring 424 inevitably have abrasion, it is necessary to periodically be replaced, above-mentioned in order to make
Positioning bead 423 and retaining spring 424 be easily changed, the clamp spring in the present embodiment is the coil component spring circle with opening, its energy
Deformation is diametrically produced, which is the opening of very little, the opening cannot be installed on the institute of location hole 422 during use
In position, in order to avoid influence the use of positioning element.The clamp spring is stuck in annular slot 425, by retaining spring 424 and positioning bead
423 closure are in location hole 422.User need to only pry open the opening of clamp spring when replacing retaining spring 424 and positioning bead 423
After dismantle clamp spring, you can positioning bead 423 in location hole 422 will be blocked and retaining spring 424 is taken out and replaced, its install with
Dismounting mode is simple, easy to the replacement of positioning bead 423 and retaining spring 424.
It these are only the preferred embodiment of the utility model, it does not limit the scope of the patent of the present invention, every
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly used in
Other related technical areas, are equally included in the patent within the scope of the utility model.
