Abstract

The utility model relates to an art design knife, particularly an art design knife which has the functions of storing spare blades, or unsealing letters or bag mouth, etc. besides the function of cutting. The art design knife is composed of a knife holder which is arranged on a shell body and provided with a blade, a moving button, and a knife lock, wherein, the shell body is formed by the integral connection of an upper shell and a lower shell, and spare knife boxes are connected inside the upper and the lower shells. When the utility model is used, the moving button is pushed to force the blade to extend outside the shell body, and the knife lock is used for locking the knife holder for use. If the blade needs exchanging, a hidden discount on the spare knife box is pressed to push the spare knife box out, then the blade is taken out, and then screws are unscrewed to open the upper shell for exchange. The utility model has the advantages of safe and convenient operation and multiple functions, and the blade is not easy to rust and break; with the exchange of spare blades, the service life of the utility model is extended.

Description

Cutter

The utility model relates to a kind of cutting tool cutter, and is especially a kind of except that having cutting function, deposits, preserves the cutter of spare blade and functions such as unpacking mail or sack in addition.

Existing commercially available cutter, various different demands various in style, complete, as to have satisfied different consumers, but it has a drawback is exactly that blade is longer, again for opening wide bareing, therefore blade very easily gets rusty or brisement, does not have spare blade again and changes, in case blade fractures, whole cutter is just scrapped and can't be used, and causes very big waste.And easily skid, use when using dangerous.

The purpose of this utility model is to provide a kind of cutter, and it is easy to use, safe, function is many, can prolong its service life, economy, material benefit.

The utility model is achieved in that cutter is made up of the tool rest that band blade, mobile button, cutter lock are installed on the housing, and described housing connects into integral body by upper casing, lower casing and constitutes, and also is connected with in upper casing, the lower casing to be equipped with the cutter box.

Fig. 1. structural representation of the present utility model (taking away upper casing);

Fig. 2. structural representation of the present utility model;

Fig. 3. user mode reference diagram (depositing, preserve spare blade);

Fig. 4. user mode reference diagram (blade hide, break seal mail).

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Tool rest (11) is the integral body that is injection molded into, and there are two clips (10) upper end of a sidewall edge, and the two edges, bottom have the slideway of protrusion to cooperate with slide rail on upper and lower shell (12), (3).The centre is mobile button (9), and the lower end is

The backstay of shape (7).

Cutter lock (8) links into an integrated entity with mobile button (9), with that technology is arranged mutually is the same.

Upper casing (12), lower casing (3) shape, structure be symmetry, corresponding substantially, can slow down impulse force when inlaying rubber fender (13), (14), (15) use in the groove of outer surface, prevent to skid; Reinforcement and corresponding reference column and blind hole are arranged on the inwall, and the inwall upper end also has slide rail; The upper end of one sidewall edge has seam respectively, it is the mobile hole of mobile button (9), cutter lock (8) that the centre has the breach of half long waist shaped respectively, the edge of breach also has equidistant sawtooth, and the two edges, lower end have rectangular indentation respectively to be hidden discount (5) and to be equipped with cutter box (4) hole; The lower end inward flange has the groove (6) that cooperates with backstay (7), and another sidewall upper has an oblique breach to be unpacking mouthful (2) respectively.One through hole is arranged in the middle of the upper casing (12), and corresponding positions is equipped with a threaded blind hole in the middle of lower casing (3) inwall.

Being equipped with cutter box (4) one sides has vertical wall, and it is opening that a side does not have wall, and the lower end is and the hypotenuse that separates at the bottom of the box that there is hidden discount (5) end, and a projection is arranged on the lower surface of top at the bottom of the box.

Spare blade (1) is put into cutter box (4) fully, in the blind hole on insertion lower casing of the projection on it (3), blade (1) utilizes clip (10) to be fixed on the tool rest (11), again the tool rest (11) of band blade (1) is put on the slide rail of lower casing (3), and the backstay (7) on it is cooperated with groove (6), cover upper casing (12), utilize the reference column on upper and lower shell (12), (3) to be connected, be linked to be an integral body with screw again with blind hole.

During use, promote mobile button (9), blade (1) is stretched out outside the housing, pull back moving knife lock (8), pin tool rest (11) and just can cut paper or three-ply board etc.

If will open mail or unnotched food bag, at this moment, can leave osculum one once pressing, so that food is taken out in unpacking with blade (1) as long as food bag is injected unpacking mouthful (2).

Time is with after long, blade is too blunt can not use the time, can press hidden discount (5), will be equipped with cutter box (4) and release, take out spare blade (1), the screw of outwarding winding again, take away upper casing (12), the blade of having used (1) is taken out from tool rest (11), change new blade (1), cover upper casing (12), screw screw again and can use again.

The utility model is compared with prior art: because whole blade all is mounted in the upper and lower shell, be sealing Formula so use saferly, is difficult for getting rusty simultaneously, fracture. And the blade that uses is lacked, can be taken full advantage of, Also not frangibility, again spare blade interchangeable, service life easy to use, as to have prolonged cutter arranged. Again Can not lose because spare blade and cutter are kept at together all the time, use, transposing is more convenient. The unpacking mouth is arranged Can break seal unnotched sack or mail etc., function is many, the scope of application is wide. And inlay on the outer surface of housing Be embedded with rubber fender, can prevent from skidding, slowing down impulsive force, good hand touch during use.
