Description
Technical field
It the utility model is related to a kind of screw location device, and in particular to a kind of screw holder.
Background technology
Self drilling tapping screw is that part more than two pieces or two pieces is generally metal or non-metal workpiece, the part of bottom
Generally metal parts is securely attached together, and a kind of fastener that can quickly, simply dismantle.It by drilling, tapping,
It is screwed into, clamps and combine together, accomplishs without any letup.Due to its advantage easy to operate, efficient, that cost is low, in building, finishing dress
Largely used in the industries such as decorations, lightweight steel construction, industrial goods production.Self drilling tapping screw is divided into two types：One kind is outer six
Self drilling tapping screw hereinafter referred to as hexagonal in angle is followed closely, and head of screw protrusion is in piece surface after it is screwed into clamping；Another kind is that cross sinks
Head self drilling tapping screw hereinafter referred to as phillips driver, head of screw sinks to piece surface or following, the screw crown after it is screwed into clamping
Portion is concordant with workpiece surface.
For operability, hexagonal is followed closely due to being constrained by interior hex screwdriver bit, and circumferential end surfaces and the hexagonal of interior hex screwdriver bit are followed closely
Coiled hair periphery be circular contact, contact area is larger, thus has preferable stability in operation, i.e., in hex screwdriver bit axis
Line is easily overlapped with hexagonal nail axis, and when work is not easy deflection and hexagonal nail can be stably loaded into workpiece.And phillips driver is not so,
Since crosspoint tip screwdriver head contact with the cross notch of phillips driver substantially belongs to point contact, contact area is small with respect to turret head,
Operation initial period due to operating force it is larger, the axial line of cross magnetism screwdriver bit is very easy to askew with phillips driver axial line
Tiltedly and shape forms an angle, therefore phenomena such as be very easy to occur the sideslip of screwdriver bit, slip.And it is firmly bigger, sideslip, slip now
As more serious.

Claw 3.
The circumferential outstanding formation block plate in the end on 1 head of base sleeve, for the foreign matters such as blocks dust enter in clamper from
And influence its use.
The end on 9 heads of trustworthy set has been connected through a screw thread end cap 12, and circumferential protrude inwardly from of end cap 12 forms thrust button, use
It is moved rearwards with synchronous drive sliding sleeve 2.Circumferential inwardly projecting formed of tail end of trustworthy set 9 hides dirt disk, different for blocks dust etc.
Thing enters in clamper so as to influence its use.
The interior hexagonal through hole for being axially arranged with inserting screwdriver bit of base sleeve 1.
The head of base sleeve 1 and afterbody are the split structure being connected through a screw thread, in favor of the assembling of whole clamper.
Embodiment three has more compact volume structure compared with embodiment two.
The utility model is that a clamper is added on the basis of screwdriver bit, to ensure screw when screwing in part with
The axle center of screwdriver bit overlaps, and increases the stability of operation, so as to avoid sideslip, slip phenomenon, improves screw and screws in efficiency.Structure letter
It is single, compact, therefore production cost is low, there is great promotional value.The corresponding modification of pawl head progress to claw 3 is set
Meter, then can be suitably used for various screws, includes but not limited to sunk screw, machine screw with oval countersunk fillister head, pan head screw etc., applies also for non-ten
The use of the screws such as example interior hexagonal of the other forms of prefix, plum blossom hole can be by varying base sleeve 1 or spring block plate 7 and screwdriver bit
Fit form is realized.
During concrete operations, by one end of screwdriver bit in the interior hexagonal through hole at 1 center of base sleeve, the other end is fitted to pneumatic screwdriver
Or in electric drill.By sliding sleeve 2 or trustworthy set 9 to pusher, so that the pawl head expansion of claw 3, spring 6 compress, spiral shell is then placed in
Nail.After loosing one's grip, due to the rebound effect power of spring 6,3 Automatic-clamping screw of claw.Then a hand holds pneumatic screwdriver or electric drill, separately
One hand handle handles clamper, then easily screw can be assembled in place.
During operation, the hand meeting nature for holding clamper applies the power to screw direction of advance to clamper.Hold
Bigger, the clamping force of the claw 3 of clamper also can be bigger, better to the stability of screw work.
Using after this clamper, screwdriver bit is worked in a manner of axial force transmission completely with screw, and race no longer occurs
Partially, slip phenomenon, can ideally complete drilling, tapping and clamp integration work.Operating time greatly shortens, work efficiency
It is significantly improved；And screwdriver bit will not be subject to the additional wear brought by sideslip, slip phenomenon again, service life obtains
Extend, correspondingly, the failure rate of pneumatic screwdriver and electric drill reduces, the service life of vulnerable part and utensil is extended, and is improved at the same time
