Description
Technical field
The utility model is related to driver technology field, more particularly to a kind of knife bar is detachable and coupling mechanism force is big screw
Knife.
Background technology
Screwdriver is used for slack adjuster as a kind of common handware, and existing screwdriver generally includes handle, knife bar
And cutter head, user drive knife bar and cutter head to rotate by rotational handle, to which cutter head drives screw rotation to carry out screw
It is elastic.It is usually fixing assembling between screwdriver and handle common at present, cannot dismantles, just compares when replacing screwdriver in this way
It is cumbersome, when screw head is different, it is necessary to match much different screwdrivers, using inconvenient to carry and of high cost.
Therefore, when also occurring many removable lining handles in the market, such as magnetic handle, but having a disadvantage in that in the presence of with one section
Between after easily de- magnetic loosely, cutter head is too short, and use is too laborious；Cutter head handle with ear has a disadvantage in that when being fixed with nut
Nutting is pretty troublesome, and head, which is broken, to be generally eliminated.
Through looking into, the Chinese patent of existing Patent No. CN200910051116.7《A kind of screw driver handle》, including shank body,
Knife bar and retainer component for fixing cutter head, the knife bar are fixed in shank body, and the retainer component is set on knife bar.This
The handle of kind of screwdriver does not change, and retainer component is arranged on knife bar, can replace different cutter heads as needed, but this knot
The stability of structure is not ideal enough, and knife bar is easily damaged, and influences the normal use of screwdriver, and knife bar cannot dismantle so that volume
Greatly, it is unfavorable for packaging storage and carries.
In addition, such as the Chinese patent of Patent No. CN201320851021.5《A kind of screwdriver》, including handle of a knife and knife bar,
It is characterized in that：The knife bar is covered by knife bar releasably to be connect with handle of a knife, and the front end of the handle of a knife axially offers a peace
Tankage, the rear portion of the knife bar set is equipped with to be equipped with and mounting groove phase with the matched interconnecting piece of mounting groove, the side of the handle of a knife
The chute hole of connection, a locking switch can be slidingly arranged in chute hole, and the bottom of locking switch is equipped with a flange, institute
It states interconnecting piece and is equipped with the limiting slot coordinated with flange, the knife bar set is plugged in the mounting groove, passes through limiting slot and institute
The cooperation for stating locking switch is locked, and be supported by between the left side of the locking switch and the inner wall of chute hole make it is described
Locking switch has always the resetting spring of sliding to the right and limiting slot locking.The handle of a knife of this screwdriver can facilitate with knife bar set
Ground shirks, but it is locked by locking switch and limiting slot cooperation, and the coupling mechanism force of this locking structure is not big enough, Bu Nengfu
Close the standard requirement in Europe.

It is very secured, and flame-resistant insulation.
When installation, spring 6 is packed into handle hole 11, the circle that two groups of buckles 4 and buckle spring 5 are packed into handle body is convex
In the ring segment slot 122 of ring 12, the rotation alignment of lid 3 buckle 4 and round bulge loop 12 are pressed into, and the convex ribs 42 of buckle 4 is made to enter rotation lid 3
Groove 33 in, finally by the handle hole 11 of the good handle body 1 of 2 plugging in fitting of knife bar, the inboard end of the square pole 21 of knife bar 2
End is oriented to chamfering 23 and coordinates with ramp projections 41, and guiding buckle 4 can adjust position, allow buckle 4 along 21 table of square pole
It is slided towards cutter head direction, when knife bar 2 is inserted into bottom, buckle 4 slides into 211 position of groove screens so that groove screens 211
It is aligned with the ramp projections 41 of buckle 4, ramp projections 41 are caught in groove screens 211 by buckle 4 under the action of buckling spring 5
Knife bar 2 is locked.
When needing replacing knife bar 2 or shirking knife bar 2, as long as rotation lid 3 is marked according to OPEN rotation arrows solids
14 are rotated clockwise, and buckle 4 overcomes the elastic force rotation of buckle spring 5 so that buckles 4 ramp projections 41 and knife bar
2 groove screens 211 is detached from, the automatic spring under the effect of spring 6 of knife bar 2, to realize that knife bar 2 is detached from handle body 1, behaviour
Make it is very convenient, it is high over there close to spring in addition, the groove screens 211 due to knife bar 2 has gradient, prevent buckle to bullet
Spring direction rotates so that the pulling force bigger that knife bar 2 can be born improves locking strength, screwdriver operate it is more convenient can
It leans on.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
