Screwdriver with Γ. auge uv ο rri α fcung sum holding the screws tight when screwing in and unscrewing

The subject of the invention is a screwdriver with a zaagenvorrichtung for securely holding Her screws it is equipped with screwing and unscrewing.

In this screwdriver, a screw is held in place by a spring that opens in a its shaft seated FMlse is housed, firmly against the Hopf of the screw, the back of which on the jaws one in the same Sleeve accommodated and from these pliers protruding below eufsit & b, is pressed after this latter cuvor äurcM Bweckerl'oiderliches Verse Loving a second ^ Ulse, which is led on the first, has been closed. Besides, they have The outer sleeve has a protruding edge on the inside that acts on it and which is so far removed from the lower edge of the sleeve that the latter pushes open on the base into which the screw is screwed and thereby the opening of the pliers before the jaws of the latter can be clamped between the said base and the screw head in this way it is achieved that the tongue device of the screwdriver for the complete screwing in of the screws no longer forms an obstacle, as has always been the case with the previously known screwdrivers of this type and that this work consequently without any interruption, i.e. without the need to move the screwdriver apart from the Remove screw au, can be done.

The inner and outer sleeves are held together by the inserted slide in such a way that one can be shifted in the longitudinal direction but not in the direction of rotation and at the same time the pliers JL1 is held by the same.

The web of this slope has a neutral bore with a somewhat larger diameter than the bore of the bent edge of the sleeve 1. · Through these bores, the tool ^{stick 14 is inserted so far that ex "1} rests with its lower thickened end on the slider _3 and protrudes freely from the top of the sleeve 1. The upper end of the shaft is designed as an animal edge for attaching a key, a drill winch, or the like, while its lower end is provided with a slot which is used to accommodate a double-edged blade made of BpeTial steel .

This is fastened by means of a screw _16 in the slot "and their

Both cutting edges preferably have different dimensions, which extends their range of use (screws of different sizes).

The slider j3 "still has several," for example vi he j threaded holes 17 uniformly distributed over its circumference, each of which is located in a different horizontal plane, and also in a hole _1δ a ball _19, which dure'i a?

The use of this screwing machine is as follows,

The screw head is pressed against the shaft after the cutting edge of the latter has been inserted into the slot in the head. - Then, while this Diuckes is preserved, the oeiden Hllleen JL and _4 will be lost together near the Soii-caube hixi. As soon as the two jaws of the pliers JJL have exceeded the Lqpf dei Schiaube somewhat , only the outer sleeve 4 will continue to move in its direction, always while maintaining the pressure on the shaft and the counterpressure on the sleeve 1 As a result, the two "said" sangenaimes are closed by the corresponding edges of the switches that cover the sleeve over the shaft of the screw cap behind its head. The screw is precisely centered by the syiB trical action of the screw jaws achieved that the screwdriver shaft by the spring _3, which ^ iei the displacement of the sleeve 1 has just been tightened, is pressed firmly against the screw head 'which sits on the angled two-long jaws

% ird. The shaft is then rotated in relation to the sleeves until it is coupled to the latter by the ball JL9 of the sliding rod J3 jumping into its cavity ZZ

The previous operations can, so to speak, be carried out in one go and have therefore hardly required.

It is now necessary to stem the Yerhältnie to the sleeve I ₁ in ae ^ ialer lease zn "block, so these" two parts when using the screw s not here- each other at the expense of the spring 2 can move. For this purpose, it is rotated until that of the threaded holes 17 of the sliding piece _3 appears in the ItLlsensehlitβ JS that is located closest to the rounded edge of this slot. After restoring the initial position of the screwdriver, a small lever screw J33 with an eccentric shaft is screwed into this Looh. It is then sufficient, as soon as a screw is detected, to turn this lever screw until its eccentric shaft comes into contact with the upper edge of the sleeve slot-6 in order to achieve the desired blocking ai.

The screwdriver is now set for use and provided that serial work is being carried out where the same screw pinhole is always used, no readjustment is required.

The screws can thus be grasped one after the other, brought into place and screwed in, using a wrench, a drill winch or some other suitable coat that can be attached to the animal edge of the shaft. As soon as the edge of the sleeve 1 protruding over the seat surface jj on the pad, in

Many times before the hood is screwed in, this sleeve snaps back and releases the screw head. This is done this verläset latter without the shaft, vws allowed.The So ¹ Iraube without interruption to the end, that is, until the braid rests firmly to screw.

Instead of connecting the sliding piece _3 and the shaft ] Λ to one another by a flexible coupling, these two parts can also be connected to one another by means of T-bolts. In this case, as shown in FIG. 4, the sliding piece is provided with an internal thread j | 4 and the shaft with a thread section Sb ₁ , and instead of the screw eccentric 23 there is a simple Lopfpchraub 36 "which the bio-bookmarking of the" tool concerned. Otherwise, the handling and the function are the same as in the first version, with the only difference that every time after a screw is completely screwed on, the shaft has to be screwed backwards again in order to make contact with its thickened end and to restore the slide J3.
