Description

A kind of geometrical clamp for binding voucher

Technical field

A kind of accounting appurtenance is the utility model is related to, more particularly to a kind of geometrical clamp for being used to bind voucher.

Background technology

It is fundamentals of financial accounting sex work to arrange and preserve accounting voucher, and accounting voucher needs fixation of binding into book form before bookbinding, in order to Punching binding, the clip for being used to fix voucher before is mainly binder clip, can only be fixed unilateral, it is necessary to while use is multiple, and And the summit in the upper left corner of voucher can not be fixed, and cause voucher easily to be tilted in drill process, increase punch operation difficulty.

The content of the invention

The purpose of this utility model provides a kind of geometrical clamp of bookbinding voucher simple in construction, easy to operate, the geometrical clamp Using the principle of triangle stability, whole voucher is securely fixed using a geometrical clamp can, and voucher be not easy it is at random, The problem of prior art is present can be efficiently solved with punching binding at any time.

Solve above-mentioned technical problem technical scheme be：It is a kind of bind voucher geometrical clamp, including train wheel bridge, lower plate, Rotating shaft and torsionspring, the train wheel bridge are connected with lower plate by rotating shaft, and torsionspring is set on the outside of rotating shaft, and reverse bullet Two spring pin of spring are against on the inside of train wheel bridge and lower plate respectively；The train wheel bridge is identical with lower plate structure, includes respectively outer Profile is the cleat body of triangle and the press section being connected in cleat body, and punching groove is also provided with the cleat body； The clamping screw for compressing voucher corner is also associated between punching groove and the press section of train wheel bridge.

The further technical scheme of the utility model is：The clamping screw includes screw body, is connected to screw body The torsion handle and platen at both ends, the train wheel bridge inner side are connected with nut, and screw body coordinates through train wheel bridge and with nut, and screw rod The platen of body front end is between train wheel bridge and lower plate.

The further technical scheme of the utility model is：The cleat body is obtuse triangle, and press section is connected to folder At the obtuse angle alpha of plate main body；The obtuse angle alpha of the cleat body is 100 °.

A kind of geometrical clamp for binding voucher of the utility model, can be to accounting voucher using the principle of triangle stability The position that need not be bound is compressed, and securely fixes whole voucher using a geometrical clamp can, and voucher is not fugitive Disorderly, voucher is bound in the state of compression, bookbinding effect is good, is not in the phenomenon that rake angle or voucher come off.

Below, the technical characteristic of the geometrical clamp of bookbinding voucher a kind of to the utility model is made into one in conjunction with the accompanying drawings and embodiments The explanation of step.

Embodiment

As shown in Figures 1 to 5, the utility model it is a kind of bind voucher geometrical clamp, including train wheel bridge 1, lower plate 2, turn Axle 3 and torsionspring 4, the train wheel bridge 1 and lower plate 2 are connected by rotating shaft 3, and torsionspring 4 is set in the outside of rotating shaft 3, and Two spring pin 10 of torsionspring 4 are against train wheel bridge 1 and the inner side of lower plate 2 respectively.

Train wheel bridge 1 of the present utility model is identical with the structure of lower plate 2, respectively the cleat body including outline for triangle 6 and the press section 8 that is connected in cleat body 6, the cleat body 6 is obtuse triangle, and press section 8 is connected to cleat body At 6 obtuse angle alpha；Punching groove 7 is also provided with the cleat body 6；It is also associated between the punching groove 7 of train wheel bridge 1 and press section 8 For compressing the clamping screw 5 in voucher corner；The clamping screw 5 includes screw body 52, is connected to the both ends of screw body 52 Torsion handle 51 and platen 53, the inner side of the train wheel bridge 1 is connected with nut 9, and screw body 52 coordinates through train wheel bridge 1 and with nut 9, And the platen 53 of the front end of screw body 52 is between train wheel bridge 1 and lower plate 2.

When binding voucher using geometrical clamp of the present utility model, the elastic force for overcoming torsionspring 4 by press section 8 acts on, To control train wheel bridge 1 and lower plate 2 to open, the voucher put in order is put between the train wheel bridge 1 of opening and lower plate 2；Unclamp Press section 8 so that voucher is fixedly clamped by train wheel bridge 1 and lower plate 2 in the case where the elastic force for turning spring 4 acts on；Turned round by turning round handle 51 Dynamic screw body 52, one jiao that voucher is needed to bind by the platen 53 of the front end of screw body 52 compress；Then beating in cleat body 6 The voucher clamped is punched at hole slot 7, bound；The release clamping screw 5 of handle 51 is turned round in twisting after the completion of operation, and is passed through Press section 8 causes train wheel bridge 1 and lower plate 2 to open, and takes out stapled voucher.

In the present embodiment, the obtuse angle alpha of cleat body 6 is 100 ° so that the space of punching groove 7 in cleat body 6 is more Greatly, bookbinding is freely threaded after the convenient punching to voucher.

Above example is only preferred embodiment of the present utility model, and structure of the present utility model is not limited to above-mentioned implementation The form enumerated of example, any modification of all made within spirit of the present utility model and principle, equivalent substitution etc., all should be included Within the scope of protection of the utility model.
