Description

Cutter with automatic tool changer function

The utility model relates to a kind of cutter, and particularly a kind of blade can promote the cutter lock with the blunt time spent again, with the spare blade that is housed in the tool rest, and the blocks of cutter that uses for transposing of releasing automatically with automatic tool changer function.

Existing commercially available cutter is various in style, and what have is provided with spare blade, and what have does not have, but general standby cutter all is the bottom that is placed on tool rest, needs during transposing back seat is taken apart, spare blade is taken out earlier transposing is installed again, and then with the back seat reinstall, troublesome poeration, use inconvenience, dangerous.

The purpose of this utility model is to provide a kind of cutter with automatic tool changer function, can change blade automatically, for market increases a kind of user of making new varieties easy to use, safe.

The utility model is achieved in that the cutter with automatic tool changer function, connects into integral body by handle of a knife and bonnet, and the cutter lock cooperates with handle of a knife and the tool rest that has blade and spare blade constitutes; Described tool rest is placed on the blade pad in the blade cartridge by blade, spare blade, and cooperates with cramp on the blade pad, and the blade pad is connected and forms on the blade cartridge handle that is fixed on the blade cartridge; Described cutter lock connects into integral body by push blade and lock, and on the push blade dash button also with the blade pad on cramp cooperate composition.

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

Blade cartridge (12) cross section is a shape, and bottom one end is an opening, and there is rectangular opening the centre, has a breach, next door to have one to dash button in addition in the middle of the end.

In the middle of blade pad (11) and blade (9) form fit, an end rectangular punching is arranged, have one in the punching vertically upward Shape cramp (4), there is an eye-splice end.

Shell fragment (10) is the strip that cooperates with blade pad (11), and an end is upturned, and the punching that the centre has through hole also is upturned, and in the middle of the end a downward punching (16) is arranged in addition.

On the two edges of handle of a knife (7) upper surface middle opening uniform circle-arc tooth is arranged, uniform arc groove is arranged on the side, in the middle of the front end face horizontal gap blade is arranged, a plurality of open slots are arranged on the rear end face, there is a rectangle punching hole bottom surface by the rear end face limit; The top of middle cavity is cutter lock chute, and centre be the tool rest chute, and the bottom is the shell fragment caulking groove, the both sides at front cross gap blade place respectively have a symmetry, and following be the plane, toply be the limited block on inclined-plane (8).

Bonnet (1) upper end is a cavity, and there are a plurality of location, fixedly inserting column, the inserted sheet of usefulness in the edge.Blade cartridge handle (2) one ends are the inclined-plane, and are fluted on the lower surface, have one on the lower surface of end in addition The shape projection.

Push blade (6) one ends upwarp, and have the circle of projection to dash button (14) and the monolateral boss piece (15) that dashes button and be complementary with blade thickness on the lower surface.

The both sides of push blade (6) one ends are transferred respectively, are coated on lock (17) the chute two edges, integrant cutter lock (5).

One end of blade cartridge handle (2) tightly is embedded on the end of blade cartridge (12), projection on it inserts in the breach of blade cartridge (12), and the eye-splice of dashing button and blade pad (11) end on the blade cartridge (12), all insert in the groove on blade cartridge handle (2) lower surface fixing, spare blade (3), blade (9) is placed on the interior blade pad (11) of blade cartridge (12), and makes cramp (4) pass spare blade (3), and the through hole on the blade (9) connects into whole tool rest (13).

Shell fragment (10) is inserted in the caulking groove of handle of a knife (7) lower end, and the punching (16) of an end is held in the punching hole of handle of a knife (7) fixing, again the tool rest (13) that assembles is inserted in the tool rest chute of handle of a knife (7), cutter lock (5) inserts in the open slot of handle of a knife (7) upper surface, at last bonnet (1) is inserted in the open slot on handle of a knife (7) rear end face fixing, cutter is assembled into, and just can use.

After long-time the use, blade (9) rust, but a section re-use after blunt part is blocked, use up up to blade (9) and do not existed.The lock (17) that at this moment can promote on the cutter lock (5) moves to the cutter anterior position, at this moment dash button (14) cramp (4) on the push type broach sheet pad (11) downwards on the push blade (6), make it be lower than the second blade spare blade (3), spare blade (3) just breaks away from stopping of cramp (4) like this, under the promotion of push blade (6) upper punch button (14), spare blade (3) with regard to automatic one grade one grade under the effect of lock (17), it is outer for using to release handle of a knife (7), by that analogy, after all spare blades (3) are used, can install spare blade (3) again additional again, for using next time.

The utility model is compared with prior art: it is simple in structure, easily device, and spare blade be with just On the blade that uses is placed on blade pad in the blade cartridge, if will change spare blade, as long as promote cutter Lock, cutter is locked rush button just can spare blade is extrapolated, do not need to dismantle again bonnet, easy to use, pacify Entirely, and cutter is locked with the boss piece identical with blade thickness, and just pad is placed on lower floor's spare blade, makes Mobile steadily, the safety of blade and cutter lock.
