Abstract

A heavy art knife, which is equipped with a reserve blade, is especially suitable for cutting hard paperboards and thin sheet spaces. The heavy art knife consists of a knife handle, a back cover and a knife base. The knife handle, which is equipped with a handle sleeve, a reserve blade and a knife holder, is connected with the back cover. The blade with a knife lock is matched with the knife base in the knife handle. A spring plate and a base buckle are respectively installed in an incision of a lock base and a groove. Two ends of the spring plate are supported on a stent of the lock base. And a lock cover is integrated with the lock base to form the knife lock. Therefore, two sides of the upper end of the art knife base are equipped with symmetric gear buckles. At the same time, base buckles and spring plates, which match the gear buckles on the two sides, are arranged on the knife lock. The blade is locked tightly by the base buckles on the two sides and the spring plates. The utility model has the advantages of even stress and stable operation, which provides the art knife with a novel structure for markets.

Description

Heavy cutter

Technical field

The utility model relates to a kind of cutter, particularly a kind ofly has spare blade, but cutting hard cardboard, thin plate sheet can guarantee blade heavy cutter safe in utilization, reliable again.

Background technology

01238562.X " cutter with auto-lock function " also provides a kind of cutter with auto-lock function, blade can not drop out, and safe in utilization, but it has different structures.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of heavy cutter is provided, and energy is safe, firm locking blade, and is easy to use, safe, and a kind of cutter product of new construction is provided for market again.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: heavy cutter by have sleeve, have spare blade, the handle of a knife of knife rest be connected and have with bonnet the blade of cutter lock cooperate with tool rest in the handle of a knife constitute, described cutter lock is not installed in the breach and groove of lock by the seat deduction of points of shell fragment, band spring, the shell fragment two end supports is on the support of lock, and locking closure and lock connect into whole the composition.

Compared with prior art, advantage of the present utility model is: there is the tooth button of symmetry the both sides, upper end of this cutter tool rest, cutter is locked seat button and the shell fragment that cooperates with two heel teeth buttons in addition simultaneously, when therefore using, blade is buckled both sides, locking that shell fragment is firm by seat, so can allow it cut thicker cardboard and three-ply board etc. safely, and stressed even, and stable working.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing

Be coated and fixed in handle of a knife (3) the central exterior surface groove for increase friction and good hand touch, on the sleeve of being made by elastomeric material (5) of sawtooth and uniform protruding grain is arranged, middle for two parallel chambeies of an opening are arranged, an end is the sloping step face that there are protruding button (12) and two chutes (15) in upper and lower surface.

Tool rest (2) is made into by metal material

Shape, the two edges of upper surface open have uniform arc tooth button (4), an end opening, and an end is inclined upwardly.

Bonnet (11) is the arc cavity, and the arc-shaped gaps groove is arranged in the middle of the outer surface, and inwall is upper and lower the groove that cooperates with handle of a knife (3) epirelief button (12), and top edge has two slideways that cooperate with chute (15) of protrusion.

Knife rest (13) one ends are the box-like of arc handle, and there is a fixture block (18) at an edge, and there is the boss piece centre, and the back side is the slide rail of projection.

Shell fragment (9) is Shape, seat button (10) is

The shape sheet metal has blind hole on the bottom surface, spring (14) is installed.

Lock (17) upper surface one end has a circle button column, and there are through hole, groove in the centre, sidewall protruding chamber jaggy, and cavity edge has a briquetting (6), and the cavity of belt supporting frame (8) is arranged in the middle of the lower surface.

Cutter lock (7) is buckled in the breach and groove that (10) be installed in lock (17) respectively by the seat of shell fragment (9), band spring (14), on the support (8) of shell fragment (9) two end supports in lock (17), locking closure (16) tightly is inserted in the middle through hole of lock (17) with projection on it, and connects into whole the composition with the limit button at its edge with lock (17).

To insert the blade (1) under lock (17) upper holder block (6) and be pressed in spare blade (1) under knife rest (13), the fixture block (18), insert respectively in the cavity on interior tool rest (2) of handle of a knife (3) and tool rest (2) limit, cover bonnet (11) at last, utilize slideway on it and chute (15) and protruding button the (12) on groove and the handle of a knife (3) to connect into integral body, heavy cutter is assembled into.

During use, only need to press moving knife lock (7) downwards, seat button (10) on it is moved down, be lower than tool rest (2) both side surface, and disengaging (2) two stopping forward of heel teeth button (4) of tool rest push away, it is outer for using that blade (1) is released tool rest (2), unclamp hand then, at this moment the shell fragment (9) on the cutter lock (7) is embedded in the tooth button (4) fixing, seat button (10) sets back under spring (14) effect simultaneously, and the tooth button (4) that is embedded in tool rest (2) both sides again is interior fixing, with blade (1) lock jail, just can work to cut out and draw cardboard, three-ply board, and blade (1) can not become flexible and drops out.
