Description

Stapler

The present invention relates to a kind of stapler, it has one to have one wide the microscler base with two leptoprosopy that link to each other with vertical limit of wide up; A top board that can be centered around the transverse axis swing on base one end is arranged, and this top board has the nail box and the pressure nail-plate in order to the extrusion staple that can hold staple; Also have a chopping block, it can be vertical along it near the base relative with bearing one end, preferably moves in two position locations or terminal location, its side who makes progress, has stamped recess to extrude setting for staple with wide parallel surface, base top and use.

The stapler of this form can be regulated the binding form of staple by mobile chopping block, promptly be the nail stitch inwardly or outwardly.Will be mobile during chopping block, a current way is arranged, be edge or the upper surface that will catch it with a finger tip, and it moved on to required direction with the pressure of finger.Owing to make not energetically, this move mode is not best.Therefore the someone proposes, and makes one and be parallel to wide on chopping block, has the little cantilever of groove.This little cantilever also can only be pushed down and can not hold with a finger tip, so if finger is moist or when guiding has some setbacks, adjustment will be with sizable power and skill.In addition, reach near the nail box head that is loaded on top board of chopping block and this is also had obstruction.For fear of this shortcoming, the someone proposes, and not on chopping block, and promotes to stretch out in base and the carriage that can brush up against from the base bottom below or with positioning reed of tightening there of finger grip.The function of this guiding mechanism is impalpable from above, need be illustrated.In addition, in the time of adjusting chopping block, stapler will be put to put and mention from it.

From this point, the basis of task of the present invention is a kind of stapler of exploitation, can regulate chopping board position with simple method, and can guarantee in the positioning action of terminal location good.

In order to solve this task, we have proposed the described structure with various features of claim 1 characteristic.Other outstanding design of the present invention and other are constructed the claim of face as follows.

Solution according to the present invention is from following imagination: if do not rely on supporting, for example help of table top can be held article with thumb and forefinger as pliers, big relatively chucking power, thereby also be that frictional force is passed to this article.If therewith correspondingly, on chopping block, there are two toward each other, relatively large-area grasping face is caught for thumb and forefinger, and so, the power of finger just can be delivered to chopping block well and get on.In order to reach this purpose, the suggestion according to the present invention, chopping block has on the vertical limit that faces one another to the leptoprosopy direction bending perpendicular to base, and overlapping partially at these, faces one another the plate of holding that side has grasping face.At a distance of a segment distance, the grasping principle that it will be designed to according to ergonomics is best size to the grasping face that faces one another on the stapler base.Holding plate can see significantly at the POF of stapler.It can additional trenches or hacking, and its function is just apparent like this, needn't be illustrated.If cross top board and hold stapler with hand, so in addition an available hand just can mobile chopping block and for example needn't rely on by desktop as the help of supporting.

Preferably make on the crimp of the whole length extending of chopping block and hold plate, chopping block is together with the profile that plate is rendered as U-shaped cross-section in fact of holding of its side like this.

Outstanding design of the present invention is two to hold the neutral gear that edge that plate respectively is embedded in the base leptoprosopy opens wide, and there, the leptoprosopy that is embedded in the grasping face of holding plate and adjacency in the neutral gear becomes straight line, perhaps exceed it one less than the distance of holding sheet material material thickness.Also have, such chopping block is suitable for being embedded in wide the neutral gear, staggered the turning to of neutral gear that the edge of wide there and leptoprosopy opens wide, and it is spacing to come that plate is held in chopping block and side thereof by in one plane end face stop side mutually.

For improve parallel conductive to, and avoid long-term the use to be made dirty, chopping block be subjected to two branches be located at both sides, be lower than wide the gib block that is arranged on the base in a longitudinal direction and lead, it should have the top edge of a horizontal rounding.In the face of the gib block that leptoprosopy sinks is preferably put up by the plate of holding that curves on chopping block from the outside.

According to of the present invention another design preferably and be, in wide of base, have two separated by a distance in the vertical, and the perforation that is separated by a transverse plate; Two in fact vertically bendings are arranged, the check plate of catching by the perforation of base downwards on the widthwise edge of chopping block; Between two check plates, along going back spring leaf of preferably being made by plastics of plug-in mounting on the longitudinal direction of base, it crosses the transverse slat of base bottom, and can be positioned at least herein on two position locations.When transverse slat and positioning reed its mutually towards side when interactional detent mechanism is arranged, positioning reed stress by bending only when mobile, and avoid easily causing the lateral stress of wearing and tearing.

For the parallel conductive of improving chopping block to, in the perforation scope of base, aim at vertically, be arranged on the side spigot surface that faces one another in couples for check plate guiding usefulness, preferably mould moulding.Like this, just be difficult in the neutral gear scope that the edge of narrow side opens wide causing lateral guide to the time wearing and tearing.If at the check plate that the chopping block widthwise edge faces one another, its lateral dimension is difference to some extent, and two side spigot surfaces also have and the corresponding different clear distances of check plate lateral dimension, just can determine that chopping block is correct being installed on the base.

Check plate is suitable makes the two sides respectively has a hanger holding spring leaf, and two terminals of spring leaf respectively have one or two catch each hanger limit tighten up projection and positioning boss.Like this, spring leaf can be tightened at the hanger of overbending direction opposite end by the detent mechanism at the center, then installs easily when the size in hanger hole is relatively large.The one side of transverse plate is done imaging triangle muscle equally the mutually oppositely detent mechanism of rising ramp, and that the one side of spring leaf has been made is circular-arc, preferably partly cylinder or spherical detent mechanism.

Elaborate the present invention by the enforcement of representing with schematic diagram below.They are:

Fig. 1 balladeur train formula goes into to follow closely the longitdinal cross-section diagram of device stapler.

The horizontal stroke and the sectional view of Fig. 2 stapler chopping block and nail box head scope, top cover does not show;

Fig. 3 a is vertical view, side view and the sectional view of the chopping block of stapler shown in Fig. 1 and 2 to c.

Staple shown in Fig. 1 and 2 is mainly by forming with lower member: a base 10 has a bearing 12 at its rear portion; The top board 14 of band nail box 16, pressure nail-plate support 18 and a top cover 20; One preferably can extrude the staple in the staple box 16 being used for as the pressure nail-plate of swingingly hanging 22 on pressing nail-plate support 18; Also have one and near the front end of base 10, can be along the longitudinal movement, and can be positioned on the chopping block 24 of two terminal locations.Chopping block has stamped

recess

28,30 at its wide 26, it optionally according to the shift position of chopping block 24 be located immediately at press nail-plate 22 and nail box 16 go out to follow closely below the groove 32, and it is inwardly curved still to excurvation that the staple pin is shaped as.What chopping block 24 formed bending vertically downward on its vertical limit 34 holds plate 36, and its two grasping face 40 that groove 38 arranged and is embedded on the neutral gear 42 that opens wide at leptoprosopy 44 edges mutually dorsad.Partly resting two sets up both sides separately for chopping block 24 dull and stereotyped, is lower than on wide 26 the gib block 46, and its lateral upper edge is crooked shape, the neutral gear 42 that the edge of its lateral surface restriction adjacency opens wide.

The

check plate

50,52 that downward bending is partly respectively arranged in the middle of the forward and backward widthwise edge of chopping block 24, they by two on base 10 perforation 54 at a distance of a segment distance embed downwards, in its underpart scope hanger 56 is arranged.Have one to be made by plastics between two

check plates

50,52, at the spring leaf 58 that base 10 is placed on vertically, its two ends are embedded in the hanger 56 of

check plate

50,52, and by plush copper 60 with its interlock be fixed tightly in the lower limb of hanger.Spring leaf 58 is under the crooked tensile stress for this reason, and this stress is to be abutted against the transverse plate 62 on the base 10 when the end positions of chopping block 24 and produced by a spherical locating convex block 64.Also having one at the downside of transverse plate, what laterally put mainly is the positioning rib 66 in cross section triangular in shape, the locating convex block 64 of spring leaf 58 is being to abut against on the inclined-plane of this positioning rib on each terminal location, when chopping block 24 must overcome the curved power of spring leaf 58 when locating convex block 64 moves.

Side guiding for chopping block 24, at the internal arrangement of base 10 side spigot surface 68, chopping block 24 nestles up it with the outward flange of its

check plate

50,52, the lateral dimension of preceding check plate 50 and back check plate 52 has difference, the side spigot surface 68 that cooperates with

check plate

50,52 then has different clear distances with it in couples, can guarantee that like this chopping block can only be installed on above the base 10 with correct direction.
