Description

Paper cutter

The utility model relates to office equipment machinery, specifically is a kind of novel trimmer.

Existing trimmer generally just is made up of base and knife rest, and cut paper thickness is little when cutting a sheet of paper, and paper is fixing, and it is inaccurate to cut size Control, and it is irregular to cut a sheet of paper simultaneously, and it is dangerous again to require great effort, and profile is not attractive in appearance yet, is not suitable for the needs of modern office chamber.

The purpose of this utility model just provides a kind of novel trimmer, and it is big to have cut paper thickness, laborsaving safety, and paper compresses automatically, and cut paper is neat, and attractive in appearance, specification is controlled well, is well suited for the needs of modern handle official bussiness.

The technical solution of the utility model is, comprises base and knife rest, wherein in a side of knife rest safety guard and the pressing plate by automatic hold-down mechanism control is housed.

Describe the utility model in detail below in conjunction with the embodiment accompanying drawing.

At first accompanying drawing is described:

Fig. 1 represents external structure of the present utility model;

Fig. 2 represents the outline drawing of safety guard;

Fig. 3 represents the connection layout of safety guard and pressing plate;

Fig. 4 represents the outline drawing of the blade in the knife rest;

Fig. 5 represents the three-dimensional structure diagram of automatic hold-down mechanism.

Referring to Fig. 1; the utility model side at knife rest (6) on the basis of the existing trimmer that is made of base (1) and knife rest (6) is equipped with safety guard (5) and passes through the pressing plate (4) that automatic hold-down mechanism is controlled; like this; in the process of knife rest (6) cut paper; because the protective effect of safety guard (5) is arranged; thereby guaranteeing has absolute security, and its security performance meets relevant world security specification fully.Pressing plate of the present utility model (4) can be tight with letterweight automatically under the control of automatic hold-down mechanism, cut paper easily not only, and also the paper edge after cutting is neat, attractive in appearance, quality is good.

Referring to Fig. 5, the two ends of pressing plate of the present utility model (4) by pressing plate shaft (7) respectively with a left side, right support (11), (10) connect, a left side, right support (11), (10) a side links into an integrated entity by connecting rod (8), rotating shaft (9) is equipped with at the middle part, a left side, right support (11), (10) opposite side is contained in base (1) by spring (12) respectively and goes up the automatic hold-down mechanism of formation, and by the end driving that is contained in the knife rest (6) on the base (1), safety guard (5) is contained on the pressing plate (4), as shown in Figure 3, the two ends of pressing plate of the present utility model (4) are owing to there is pressing plate shaft (7) to support, so, paper can be come in and gone out freely from the space at pressing plate (4) middle part, and by a connecting rod (8) and a left side, right support (11), (10) connection is in aggregates, when external force P gives a side application of force of left socle (11), whole hold-down mechanism just rotates around rotating shaft (9), pressing plate (4) is lifted, promptly can put paper, after external force P disappears, a left side, right support (11), (10) backward rotation under spring (12) effect, pressing plate (4) is tight with letterweight, promptly can cut a sheet of paper.External force P can be applied by an end that is contained in the knife rest (6) on the base (1), when an end of knife rest (6) lifts, the other end of knife rest (6) is to pressing down, thereby a side that drives left socle (11) is rotated around rotating shaft (9), pressing plate (4) lifts, paper is put well, with knife rest (6) to incision, the other end of knife rest (6) lifts, discharged left socle (11), promptly external force P disappears, hold-down mechanism backward rotation under spring (12) effect, pressing plate (4) compresses paper automatically, thus compressing automatically when having realized cut paper.Safety guard (5) is contained on the pressing plate (4) and had both played the safeguard protection effect, the turnover of not overslaugh paper dress again, and novel structure designs ingenious.

The utility model is equipped with the scale (3) of band English, mounce kind scale on base (1), positioned cursor (2) is contained on the scale (3), and as shown in Figure 1, positioned cursor (2) can go up at scale (3) and move arbitrarily and locking, so that cut the paper of arbitrary dimension, and size is accurate after cutting.Be marked with the specification standards line of paper at the panel of base (1), can be accurate and cut the paper of standard specification easily.

The blade shapes of knife rest of the present utility model (6) is a circular arc, and as shown in Figure 4, the blade shapes of shape uniqueness makes the edge of a knife sharp through special processing, and cut paper thickness is big, and is laborsaving, and the life-span is long.Safety guard (5) adopts lucite to make circular arc, and as shown in Figure 2, lucite can be observed the working condition of safety guard (5) opposite side, garden arc safety guard (5) not overslaugh people's operation.

The novel trimmer novel structure that the utility model provides, reasonable in design, it also is equipped with safety guard on the basis of existing base and knife rest, guarantee that knife rest has the security when cutting paper, and its security performance meets relevant world security specification fully; The automatic hold-down mechanism of one cover is housed, can be automatically that letterweight is tight in the process of cutting a sheet of paper, the paper edge after cutting is neat, attractive in appearance, and the blade in the knife rest is through special processing, the shape uniqueness, the edge of a knife is sharp, the life-span is long, and cut paper thickness is big, and is laborsaving; But also scale and the positioned cursor of being with English, hectogram kind scale is housed, and the paper scale of various standard specifications is arranged on the base panel, therefore can accurate touch the accuracy that inerrably guarantees paper cutting, and good looking appearance, volume is light and handy, the efficient of cutting a sheet of paper height, quality is good, is the desirable apparatus of modern handle official bussiness.

Accompanying drawing has been represented specific embodiment of the utility model.

Referring to Fig. 1, safety guard (5) adopts pmma material to make the circular arc that radius is R2, as shown in Figure 2, be connected on the pressing plate (4) with screw (13), as shown in Figure 3, blade in the knife rest (6) adopts tool steel to be processed into the circular arc that radius is R1, as shown in Figure 4, knife rest (6) is screwed on base (1), base (1) adopts the sheet metal bending forming, surface plastic spraying, the panel of base (1) be marked with A3, A4 ... etc. the normal line of several working standard paper sizes, scale (3) and positioned cursor (2) are housed.Automatically the structure of hold-down mechanism as shown in Figure 5, except that pressing plate (4), remaining parts: pressing plate shaft (7), left and right support (10), (11), spring (12), connecting rod (8), rotating shaft (9) all are positioned at base (1), and knife rest (6) can apply power P for automatic hold-down mechanism by pulley.
