Abstract

The utility model discloses a lever pressurized stapler which is labor saving in operation and neat in bookbinding. The lever pressurized stapler is suitable for various kinds of staples be sold in market. The lever pressurized stapler makes use of lever principle to fix a bracket onto a base; the bracket is connected with a lever of force to form a hinge. The bracket is served as the fulcra of the lever. The forcing point of the lever of force is at the rear part of the lever pressurized stapler. A forcing point of a roller is at the front part of the lever of force. While in operation, the forcing point of the lever of force is pressed down, and the forcing point of the roller rolls on a travel-range bevel on an upper pressing box in order to press down a stapler mechanism. The base is provided with a moveable catch pawl which is adjusted by a screw to move front and back. The width of the remained hem of a book be bound can be adjusted by turning a hand wheel on the rear part of the base.

Description

Lever pressurized stapler

The utility model is a kind of stapler of being made up of base, supporting plate, nail box and last pressure box etc. that relates to.

Selling now maximum on the market is exactly this stapler, when using this stapler, with the moving front end of pressing box of going up of hand, finishes bookbinding.Both required great effort like this, again because blocking of hand influences sight line, a book two nails are difficult to order point-blank.

Task of the present utility model provides a kind of stapler, in the reinforcing of the rear portion of stapler, goes up the pressure box by the leverage compressing and operates during use, and is not only laborsaving but also do not influence sight line, requires to make each nail in addition all point-blank when a book is followed closely more.

Task of the present utility model is that following mechanism finishes: also be fixed with a support (7) on stapler base (1), be positioned at the both sides of supporting plate (2), nail box (4) and last pressure box (6), there is disjunctor small rack (20) support (7) rear end, bottom, this disjunctor small rack (20) with the nail box (4), on press box (6) to be connected with hinge (14), support (7) top front end is connected with hinge (8) with the front end of the arm of force (13) that plays the lever pressurization, become the fulcrum of lever, the arm of force (13) is stretched towards the back upper place of support (7).Last pressure box (6) front, top is fixed with stroke inclined-plane (9), by having put a cylinder (11) of fixedlying connected with the arm of force (13), upwards presses box (6) to apply the stress point of active force as lever system on this trip inclined-plane (9) part.When in the reinforcing of the arm of force (13) rear portion, cylinder (11) rotates around fulcrum, and stroke inclined-plane (9) are formed the active force that rolling presses down, depress box (6), finish bookbinding, so both reduced friction, it is big to have overcome lever force stroke again, the deficiency that the application point stroke is little, and reach the purpose of rapid operation.

The utility model also partly has a horizontal concrete chute (22) at base (1) crown center, chute (22) central authorities have vertical slotted hole (21), base (1) rear end face has a horizontal oblong aperture (23), chute (22) is to staple together for adjustment to stay the narrow horizontal rail of establishing catch pawl (3) of hem width, catch pawl (3) moves forward and backward along support (7) both sides, the place ahead, and the disjunctor screw (24) of catch pawl (3) matches with screw flight end (19) by the vertical slotted hole (21) on the base (1).The polished end of screw rod (17), pass the sliding fit hole and spring (16) that is fixed on the carriage (18) on base (1) bottom surface, rear end after, fix with handwheel (15).The disjunctor screw (24) of carriage (18) and catch pawl (3) makes screw rod be in horizontal level, spring (16) handwheel (15) to pusher, make catch pawl (3) not reason handwheel (15) move forward with the gap of horizontal oblong aperture (23).Handwheel (15) is projecting inward in the horizontal oblong aperture (23) of base (1) rear end face, rotates handwheel (15) and drives catch pawl (3) by screw rod, makes it move forward and backward that regulating staples together and stay the width on limit.

The utility model is easy to operate, and support and the arm of force can be made suitable animal-shapedly, makes it have artistry and ornamental.

Fig. 1 is the structural representation (book extract accompanying drawing as an illustration) of the utility model lever-style booster stapler.

Fig. 2 is the view of the part stent (7) of stapler among Fig. 1.

Fig. 3 is the view of the parts base (1) of stapler among Fig. 1.

Fig. 4 is the view of the parts catch pawl (3) of stapler among Fig. 1.

1 to 4 couple of embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.

With reference to Fig. 1, Fig. 2, the metallic support (7) with good mechanical strength, is also fixed carriage (18) on base (1) with the bolting of 4 M3 simultaneously in the bottom surface, rear portion of base (1).Here support (7) is made the physical shapes moulding of pigeon with 1mm iron plate, its rear end is shaped on the disjunctor small rack (20) that upwards bends up, with nail box (4), on press box (6) the rear end connect into hinge (14) with the rivet of φ 3mm, the front end of nail box (4) and the supporting plate (2) that is connected in support (7) front end match.Rivet with φ 3mm connects into hinge (8) at the front end of the support (7) and the arm of force (13), and as the eyes of pigeon, the arm of force (13) is made the crown, back and the moulding of afterbody profile of pigeon with 1mm iron plate simultaneously.Rivet (10) is outer to be with the front portion that cylinder (11) is fixed in the arm of force (13), is 1/3 place of the arm of force (13) length overall approximately, calculates according to theory like this, during operation laborsaving approximately 1/2.Stroke inclined-plane (9) is fixed in the front end of pressing box (6) with bolt (12), also will press nail-plate (5) fixing simultaneously, and stroke inclined-plane (9) contact with cylinder (11), and the arm of force (13) was in suitable height and posed positions when this machine was not worked.With reference to Fig. 3, Fig. 4 base (1) middle part has a horizontal concrete chute (22), have a vertical slotted hole (21) again in horizontal concrete chute (22) central authorities, base (1) upper rear end has a horizontal oblong aperture (23), catch pawl (3) upwards bends up part and is slidingly matched in the both sides, the place ahead of support (7) bottom, the disjunctor screw (24) of catch pawl (3), match with screw flight end (19) by the vertical slotted hole (21) on the base (1), it is fixing with handwheel (15) that polished end (17) is passed the sliding fit hole and spring (16) back of carriage (18), handwheel (15) in the horizontal oblong aperture (23) of base (1) rear end face, about 3 millimeters of plane, protruding end.
