The present invention relates to a kind of file puncher, it has a base (10), a pressure handle (18) that rotates on base (10) two-side supporting plate.The bounce that this pressure handle (18) can be resisted a spring (28) can move the punching head on the base (10).Also have a backstop shoulder (26) that is installed on the support plate (14) in addition, it is at the stop part (32) that withstands under the bounce effect of spring (28) on the pressure handle (18).Stop part (32) is the whole slide block of being made by plastic cement (32), it is located in the slotted hole of pressure handle (18), and it is removable between its two terminal location, on the end position that pressure handle (18) is depressed, slide block (32) constitutes a part that bears down on one that presses closer at last retaining shoulder (26), and on another terminal location the time, can make the swing of pressure handle (18) easy on and off.

Description

File puncher

The present invention relates to a kind of file puncher, it has a base, and the bounce that a pressure handle that rotates on base two-side supporting plate, this pressure handle can be resisted a spring can move the punching head on the base.Also have a backstop shoulder that is located on base or the support plate in addition, it withstands a stop part on the pressure handle under the bounce effect of spring.

With regard to this disclosed file puncher, pressure handle is when being depressed and not being depressed situation, and stop part has the function of location, two ends.In addition, particularly for the overhanging long card punch of those pressure handles, in order to help transportation and stock, need be locked in the position of depressing to pressure handle, but just in order to transport, most applications then is need not be wooden or the part that bears down on one of plastics, just use up and lose, this is uneconomic.

Task of the present invention is: create a kind of card punch of the above-mentioned type, it has one and is positioned on pressure handle card punch inside, that can be convenient to make and the install part that bears down on one.

The present invention mainly is a kind of stop part, and it is one and is positioned in the pressure handle slotted hole integral plastics slide block that can move between the end positions of slotted hole.On the end position that pressure handle forces down, slide block constitutes the part that bears down on one that presses closer the backstop shoulder, and can make the swing of pressure handle easy on and off on other end position.

According to an optimal design of the present invention, a band neck operating head that can cross the pressure handle slotted hole is arranged on the slide block, this operating head has the lug of being close to the slotted hole longitudinal edge, this operating head preferably in installation process, aim at slotted hole longitudinally lug can pass slotted hole, then with the slide block half-twist, operating head just can be locked in the guide rail that is parallel to slotted hole on the pressure handle with slide block, pressure handle preferably is provided with two in a certain distance apart from one another for this reason, be parallel to slotted hole, constitute the gib block of guide rail, and the backstop slide block is provided with a rib relative with the backstop shoulder, be provided with two guide edges in addition, article one, guide edge is in the face of rib, is wedge shape or side declivity and slides on certain bar gib block of pressure handle; The second guide edge is relative with article one gib block with rib, and slides on pressure tongue second gib block.In addition, be preferably with an allocation tongue that is located at second guide edge side on the backstop slide block, by means of this allocation tongue, slide block can be locked in pressure handle at the end that pressure handle is swung up and down another to locking member on.

The relative slide block of the rib of slide block plane preferably is wedge shape, and so, the most of pressure that produces by the bounce-back spring is transmitted to the inboard of pressure handle, and does not just act on second narrow gib block.The relative locking member of gib block, slotted hole and allocation tongue more reasonably is provided in a side of on the shield section that faces down of restriction pressure handle.

The present invention is further illustrated by means of the embodiment that represents with schematic diagram below, and they are:

Fig. 1. be with the schematic diagram of the file puncher of the part that bears down on one;

Fig. 2. the part of the card punch of Fig. 1 when pressure handle is depressed cutd open side view;

Fig. 3. the top view of backstop slide block;

Fig. 4. the side view of the backstop slide block of Fig. 3;

Fig. 5. the front view of the backstop slide block of Fig. 3 and Fig. 4.

Fig. 1 and cast iron card punch shown in Figure 3 are mainly formed to be had: 10, two of base is positioned at the side bearing plate 14 of base 10 both sides and one and is positioned on pressure handle 18 on the side bearing plate, that can carry out limited rotation around rotating shaft 16.Pressure handle 18 both sides are bowed downward to limit group 20, its outside and side bearing plate 14 overlap joints, and pressure handle 18 also has the shield 22 crooked, that help to be connected with each other with the limit that faces down.The supporting plate 24 that is upturned is arranged in side bearing plate 14 fronts, support under the shield 22 of pressure handle, supporting plate 24 constitutes the upper edge of backstop shoulder 26 at it under the effect of spring 28, withstand one on the pressure handle 18 as end stop and in the stopping dam 30 that protrudes.

In addition, be provided with at the position of the shield 22 of pressure handle one can be traversing backstop slide block 32, it passes shield 22 slotted holes 36 at neck 33 and operating head 34 and is pressed in the front of shield.

As the backstop slide block 32 of plastic cement die casting when mounted its operating head 34(is aimed at slotted hole 36 vertically on lug 38 is arranged) pass slotted hole 36, half-twist then, lug 38 just closely is overlapped on the longitudinal edge of slotted hole 36 like this.Simultaneously, the

side guide edge

40,42 of backstop slide block 32 has been drawn between two

outstanding gib blocks

44,30 that are located at the shield inboard.Following guide edge 40 is tiltedly facing to backstop slide block plane.Adjacent with following guide edge 40 is an inclined flange 48 of establishing by opposed limit, and it is meshed as the part that bears down on one of pressure handle 18 with the backstop shoulder 26 of adjacent supporting plate 24.The last gib block 30 that acts on backstop slide block 32 is simultaneously as the terminal stop part that withstands the backstop shoulder 26 of supporting plate 24.Prolongation at last guide edge 42, be extended with allocation tongue 50, when the backstop slide block withdrawed from stop dog position and enters another terminal location, the positioning head 52 on the allocation tongue 50 just locked one on the pressure handle being located on another relative locking member on the shield (22) of not expressing.
