Abstract

The utility model discloses a labor-saving stapler, belongs to office supplies and mainly solves a problem that a conventional stapler is time-wasting and force-wasting when stapling thick documents. The labor-saving stapler comprises a stapler body, wherein the stapler body comprises a power arm, a foldout, an extension bar and a resisting arm, wherein the power arm and the resisting arm are connected by a rotary shaft to form the stapler; a transverse groove is formed in the upper surface of the power arm; the length and the width of the groove are a slightly larger than those of the extension bar; the extension bar is hinged at the tail end of the power arm by the foldout. The labor-saving stapler has a simple structure, is safe, convenient, time-saving and force-saving to use.

Description

A kind of labour-saving stapler

Technical field

The utility model relates to a kind of office appliance, specifically is a kind of labour-saving stapler.

Background technology

As everyone knows, stapler is to utilize the lever principle take rotating shaft as fulcrum to carry out work, it provides many page or leaf paper desirable means of being preserved stapled together for us, stapler must be placed on the smooth desktop during use, because the thickness of bound document is different, firmly also different, for thicker file, during bookbinding in requisition for pressing the horn of stapling together with great strength, so that nail penetrates the paper that is in sheets fully, can require great effort very much like this, be not easy to operation.

The utility model content

The purpose of this utility model is to provide a kind of labour-saving stapler, and this stapler has convenient, the time saving and energy saving function of bookbinding.

The technical scheme in the invention for solving the technical problem is: a kind of labour-saving stapler, comprise the stapler body, it is characterized in that, described stapler body is made of power arm, folding, extension bar and resistance arm, power arm and resistance arm are connected to form stapler by rotating shaft, upper surface at power arm is provided with groove, and the length of this groove and width all are slightly larger than extension bar, and extension bar is hinged on the end of power arm by folding.

The beneficial effects of the utility model are: thicker such as the file of bookbinding during use, and automatically to pull out extension bar in the groove of the arm of force and turn to power arm on same straight line along folding place, this moment, power arm lengthened, can be very laborsaving during bound document; After the use extension bar is back in the groove of power arm, can makes the stapler volume little, be convenient to deposit and carry; The utility model is simple in structure, uses safety, convenient, time saving and energy saving.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Among the figure: 1 power arm, 2 foldings, 3 extension bars, 4 resistance arms.

The specific embodiment

As shown in Figure 1.A kind of labour-saving stapler, comprise the stapler body, described stapler body is made of power arm 1, folding 2, extension bar 3 and resistance arm 4, power arm 1 and resistance arm 4 are connected to form stapler by rotating shaft, upper surface at power arm 1 is provided with groove, the length of this groove and width all are slightly larger than extension bar 3, and extension bar 3 is hinged on the end of power arm 1 by folding 2.

During use, thicker such as the file of bookbinding, automatically to pull out extension bar 3 in the groove of the arm of force 1 and turn to power arm 1 on same straight line along folding 2 places, this moment, power arm 1 lengthened, can be very laborsaving during bound document; After the use extension bar 3 is back in the groove of power arm 1, can makes the stapler volume little, be convenient to deposit and carry; The utility model is simple in structure, uses safety, convenient, time saving and energy saving.
