Description
Technical field:
The utility model relates to a kind of hand papercutter that cuts the papery article.
Background technology:
At present, the prior art hand papercutter generally is by an iron plate and the location that magnet is realized institute's cut paper is opened when cut paper, its operation principle is exactly to utilize the magnetic force of magnet iron plate to be fixed on the base of hand papercutter, and when cut paper, one end of paper is withstood on the iron plate, thereby realize location that institute's cut paper is opened.The magnetic force of some magnet adopt iron plate and magnet to come locating paper sheets to have a weak point: though can reach very strong degree at present, but the location that can come random mobile iron plate and magnet to realize diverse location according to the needs of antiquarian for the ease of the user, and the magnetic force that is used for the magnet of prior art hand papercutter generally is not very strong, this firmness that makes iron plate be connected with base down in working order is not enough, easily because of user's undue force makes iron plate displacement, thereby cause the cut paper Zhang Dingwei of institute inaccurate and influence the size that institute's cut paper is opened.
The utility model content:
The technical problems to be solved in the utility model is, provide a kind of can be to the accurate hand papercutter of location of the cut paper Zhang Jinhang of institute.
Technical solution of the present utility model is, a kind of hand papercutter with following structure is provided, and it comprises base, be connected knife rest on the base and vertical each other positioning guide rail and positioning strip; Described positioning guide rail is fixedly connected on the upper surface of described base; One end of described positioning strip and positioning guide rail sliding fit; Be provided with one between described positioning strip and the positioning guide rail and can limit the positioning strip locking device that positioning strip slides.
After adopting above structure, compared with prior art, the utlity model has following advantage: the positioning guide rail described in the utility model is to fixedly connected with the hand papercutter base upper surface, and positioning strip can be fixedlyed connected with positioning guide rail by the positioning strip locking device, therefore positioning guide rail described in the utility model and positioning strip can not produce displacement because of user's undue force down in working order, thereby have guaranteed that the utility model hand papercutter can accurately locate the cut paper Zhang Jinhang of institute; In addition, positioning strip can guarantee the same paper that cuts out different size with the prior art hand papercutter of the utility model again with sliding fit between the positioning guide rail.
As a kind of improvement of the present utility model, be equipped with scale label on the upper surface of described positioning guide rail and positioning strip.At positioning guide rail and positioning strip upper surface the accuracy that scale label can further improve the utility model paper location is set.
Description of drawings:
Fig. 1 is the structural representation of the utility model hand papercutter.
Fig. 2 is the structure for amplifying schematic diagram of location-plate in the utility model.
Fig. 3 be among Fig. 1 not the A during connected positioning plate to the partial structurtes enlarged diagram.
Fig. 4 is the structural representation when the positioning and fixing post is clipped between location-plate positioning seat inclined-plane and the positioning seat left side outer wall among Fig. 3.
Shown in the figure: 1, base, 2, knife rest, 3, positioning guide rail, 4, positioning strip, 5, knob, 6, screw rod, 7, the positioning and fixing post, 8, connector, 81, the inclined-plane, 9, fixing reinforced seat, 10, the hole.
Specific embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, in this specific embodiment, the utility model hand papercutter comprises base 1, be connected knife rest 2 on the base 1 and vertical each other positioning guide rail 3 and positioning strip 4; Described positioning guide rail 3 be welded on the cross section be "
" on the fixedly reinforced seat 9 of shape, described fixedly reinforced seat 9 vertically is welded on the upper surface of base 1; One end of described positioning strip 4 and positioning guide rail 3 sliding fits; Be provided with one between described positioning strip 4 and the positioning guide rail 3 and can limit the positioning strip locking device that positioning strip 4 slides, the concrete structure of this positioning strip locking device in this specific embodiment is as follows: it comprise knob 5, screw rod 6, positioning and fixing post 7 and with the connector 8 that is connected positioning strip 4 bottoms; Be equipped with a hole 10 on described positioning strip 4 and the connector 8, these two holes 10 are overlapped; Intert in hole 10 described knob bottom 5, thereby realize rotatable cooperation the between described knob 5 bottoms and positioning strip 4 and the connector 8; Described screw rod 6 screws in the screwed hole of knob 5 bottoms; Fixedly connected with positioning and fixing post 7 in described screw rod 6 bottoms; Described connector 8 is slidingly matched with positioning guide rail 3; There is an inclined-plane 81 lower end of described connector 8 vertical components; When the axis of described positioning and fixing post 7 and positioning guide rail 3 are parallel also with the axis normal of screw rod 6; Described positioning and fixing post 7 is between the left-external side of inclined-plane 81 and positioning seat 3; Distance between 81 tops, described inclined-plane and the positioning guide rail 3 is less than the diameter of positioning and fixing post 7.In this specific embodiment, be equipped with scale label on the surface of described positioning seat 3 and location-plate 4.
The operation principle of the utility model hand papercutter is: as shown in figures 1 and 3, when positioning and fixing post 7 is not clipped between the left-external side of inclined-plane 81 and positioning guide rail 3, user's positioning strip 4 that can arbitrarily slide; When the user need stop positioning strip 4 slips, as long as turn knob 5, this moment, knob 5 moved up screw rod 6 by its screwed hole, driving positioning and fixing post 7 when screw rod 6 moves up moves up, when positioning and fixing post 7 tightly withstands between the left-external side of inclined-plane 81 and positioning guide rail 3, step on the knob 5 has also just withstood on the surface of positioning strip 4, positioning strip 4 just can't slide and be fixed on the positioning guide rail 3 at this moment, after positioning strip 4 maintained static, the user just can open institute's cut paper and position.
It is described that the utility model is not limited to the foregoing description, and promptly the utility model is not limited to by fixing reinforced seat 9 positioning guide rail 3 is fixedly connected on the base 1, and described positioning guide rail 3 can directly be fixedly connected on the base 1; In addition, the utility model also is not limited to and uses cooperating between positioning and fixing post 7 and inclined-plane 81 and positioning seat 2 left-external sides, it also can not be provided with inclined-plane 81, and at hook of the bottom of screw rod 6 connection, and a groove with certain-length is set at positioning seat 2 left outer walls, realize locking thereby make hook can be hooked in groove and connector 8 bottoms to positioning strip 4; Also have, positioning strip 4 and connector 8 also can be made of one, and more than change all falling into protection domain of the present utility model.
