Abstract

The utility model discloses a stapler without staples, which is composed of a base bottom, a support frame, a pressing cover, a punching pressing shaft, a punch, a paper retreating mechanism, a spring, etc. The utility model utilizes a punch of a special cross section to use the punched and sheared portion separated from the base body as the binding connecting member. Thus no staple easy to rust is needed fro connection. The utility model can avoid pollution caused by printing articles with long term storage and bind various paper no more than 10 pages. The utility model is particularly suitable for binding of documents and bills. The utility model has the advantages of high connection strength, little possibility of separation, no staple and low operating cost. The utility model is revolution of a stapler, which can independently achieve binding or replacement of the existing stapler.

Description

The needleless stapler

The utility model relates to file, bill binder.

No matter whether thickness is always finished by stapler or puncher in the bookbinding of file, bill, traditional stapler all is to bind with staple, utilize staple to realize connecting, but the long preservation staple easily gets rusty, pollute printed matter, tired brain, the especially file within 10 pages that also can run into no staple sometimes and can not bind, bill bookbinding.

The purpose of this utility model just be to provide a kind of paper thick within 10 pages, do not need the needleless stapler of staple, avoid staple to get rusty, pollute the printed matter phenomenon.

The purpose of this utility model solves by following technical proposal: include base, be located at base top and with its fixing support, front end and support are hinged, the rear end is cantilever-shaped gland, it is characterized in that described gland inside top is provided with parallel with jointed shaft and is higher than the ram axle of jointed shaft, the effect that is subjected to the ram axle pushing force moves up and down along pilot hole and realizes drift towards 2-3 odd-shaped cross section of paper, the lower portion of ram cutting edge has the oblique angle of retreating α, corresponding drift is located at the cutting edge on the base and moves back mechanism of paper, and the spring that drift is resetted.

The utility model utilizes drift to carry out the paper punching, because the drift cutting edge has the oblique angle of retreating α, so does not separate with matrix the punching rear section, separated part is as the bookbinding connector, therefore its staple of not needing easily to get rusty connects, and avoids the long-term pollution that keeps printed matter, is suitable for binding the various paper within 10 pages, the bonding strength height, not easily separated, needleless has also reduced use cost, can finish independent bookbinding, also can replace existing puncher, be the revolution of machine of stapling together.

Description of drawings:

Fig. 1 is the utility model sectional structure schematic diagram.

Fig. 2 sheds vertical view behind the above part of support for Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 1.

Below with reference to above-mentioned accompanying drawing embodiment the utility model is described in detail again.

Referring to Fig. 1-3, the needleless stapler includes base (1), and the base bottom is provided with the bottom (10) of setting-in demountable rubber system.

The base top is provided with the support (9) with its riveted and fixed, support both sides bending rectangular shaped, gland (2) front end is hinged on the preceding top of support with bearing pin (3), it is cantilever-shaped that the rear end is, cradle top surface is provided with fixing guide plate (6), is provided with the side plastic sealing plate (8) with the bonding agent adhesion between guide plate and the support rear portion.

Gland (2) inside top is provided with parallel with hinging pin shaft and is higher than the ram axle (4) of hinging pin shaft, and ram axle is as inserts and gland integrated through injection molding.Moved up and down along pilot hole by the effect of ram axle pushing force and realize drift (7) towards 2-3 odd-shaped cross section of paper, odd-shaped cross section can be

Shape or

Shape for easy to process, got the former and is advisable, and is good with 2 drifts, is connected into by pressure head plate (5) to be

The monoblock type of type, ram axle contact with line with the pressure head plate and transmit pressure.The pilot hole that drift moves up and down comprises the coaxial pilot hole on guide plate, the support bottom surface, and promptly drift serves as that guiding moves up and down with above-mentioned 2 coaxial pilot holes.The lower portion of ram cutting edge has about 15 ° of the oblique angle of retreating α, guarantees that the paper of punching does not separate with body portion, and corresponding drift has corresponding cutting edge (14) on base.

The mechanism of paper that moves back that corresponding drift is located on the base comprises the fixed mount (11) that is fixed on the inboard corresponding cutting edge of base, and what fixed mount and base cutting edge were filled with soft rubber system moves back paper device (12), moves back mechanism of paper and guarantees drift punching task.

Resetted by spring (13) after the drift punching, spring can be established 2-3, divides between the drift that is located in the support or both sides, when adopting 2 springs, divides the both sides that are located at 2 drifts; When adopting 3 springs, divide be located in the middle of and both sides, present embodiment is selected first scheme for use, 2 springs are located at and pass the guide plate preprocessing hole in the support and act on the pressure head plate, reset by the moving drift of pressure head strip.

To bind manuscript when using this stapler earlier and put down folding on request; Put into the limit of rolling well below the drift and locate; Carry out punching press with the hand pressure about 2Kg; The punching press defensive position is loosened drift and is resetted under spring action, take out then manuscript will put down the folding place again row launch, promptly finish the bookbinding task, with the matrix separated portions manuscript is linked mutually under the punching.
