Holder for a straight knife in a hand stapler

The invention relates to a holder for a straight knife in a hand-held stapler for ejecting staples, which are stored in a rod-like manner on a magazine, with the push knife to reduce friction is movably arranged.

To reduce the friction of the straight knife when ejecting the staples guided on the magazine Knife holder known that are riveted or spotted in the upper part of the hand stapler. In these Knife holders, the straight knives are freely suspended. The disadvantage of these designs is quite elaborate constructive training and installation. The one used to hang up the straight knife Mesierhalter must be profiled accordingly and firmly attached to the inner wall of the upper part of the hand-held stapler be arranged, e.g. B. by riveting. A riveting of the knife holder remains after completion of the hand stapler visible. Before a final surface treatment of the hand stapler

the externally visible connection points of the knife holder must be treated so that a relative smooth outer surface can be achieved.

The invention is based on the object of a holder for a knife holder in a hand stapler to create the type shown, which is structurally simple and extremely fast and can be easily inserted into the upper part of the hand-held stapler, with no post-treatment on the outer surface visible connection points is required.

This object is achieved according to the invention in that the straight knife pendulum in one in the upper part of the housing arranged leaf spring is stored = In an embodiment of the invention, the leaf spring is under Pre-tensioning clamped in the upper part of the hand-held stapler, preferably installed with an upward curve. In a preferred embodiment, the end faces of the leaf spring are provided with profiles, which can be designed in the form of cams or points. There is also the option of using the leaf spring to be stored in recesses in the inner wall of the upper part.

Further features of the invention emerge from the remaining subclaims.

The leaf spring, together with the push knife, is subsequently inserted into the finished upper part of the housing

Hand stapler can be brought in without affecting the external appearance is affected. The push knife holder according to the invention is on the outer surface of the upper part of the housing not visible. Due to the profiling of the end faces of the leaf spring in the event of a load as a result of the occurring deflection, the friction on the one used as an abutment Inner wall of the upper part of the housing improved. The concentrated transmission of the contact pressure leads for cutting the profiles into the interior

An embodiment of the invention is shown in the drawing and will be described in more detail below 15 described. Show it

Fig. 1 is a side view of a hand stapler;

Fig. 2 shows a cross section through a housing upper part 2.0 and

3 is a plan view of a leaf spring.

A leaf spring 3 is curved upward under bias and extends in the upper housing part 2 of a hand-held stapler clamped. A straight knife 1 is mounted in a slot 6 of the leaf spring 3. The end faces 5 of the leaf spring 3 are provided with profiles 4 in the form of points as shown in FIG. That Knife 1 is known to have a recess 7. On the axis 8 are the upper housing part 2, the magazine 9 and the base plate 10 are stored.
