The structure of the knife lock is simple, the number of the part is little, just three parts, and the assembly can be carried out only by embedding the lock catch in the groove on the lock seat, and buckling on the lock cap. The assembly is convenient and the disassembly is easy, the operation is convenient and safe, and the utility model can be used by being matched with the utility knives with various different structures.

Description

The cutter lock of cutter

Technical field

The utility model relates to a kind of critical piece that cuts paper, the used cutter of thin plate sheet, on particularly a kind of blade that is connected cutter,, control blade supporting with cutter moves it or makes its braking, locking, guarantees the cutter lock of the cutter of blade trouble free service, use.

Background technology

The patent No. 99252576.4 " automatic locking of cutter " can be pinned blade automatically though also provide a kind of, easy to use, safe, and fastening durable automatic locking, and its part is more, the assembling trouble.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of cutter lock of cutter is provided, can moves, pin blade, easy to use, safe again, and simple in structure, part is few, easy demolition, installation, and a kind of cutter lock of new construction is provided for market.

The utility model solve the problems of the technologies described above the technical scheme that adopted by: the cutter lock of cutter by locking closure, lock and on locking, mobile device connect into whole the composition, described locking, mobile device are to be connected with lock, and the snap close that cooperates with locking closure.

Compared with prior art, advantage of the present utility model is: the cutter lock of this cutter, it is simple in structure, part is few, have only three parts, only snap close need be embedded in the groove on the lock, buckling locking closure can be assembled into, easy for installation, quick detachable, and easy to use, safe, can with the supporting use of the cutter of various different structures.

The specific embodiment

Embodiment is further described the utility model below in conjunction with accompanying drawing: the knurling that increases friction is arranged on locking closure (3) outer surface, there is flange at inner surface one edge, it is circular arc that its middle position also has the end, the cross section is an eye-splice (5) of rectangle, a positioning block (9) is arranged in the middle of the edge in addition, the rectangular conduction through concave trough (8) at its place is divided into two grooves that do not communicate.

Lock (2) one ends are for there being the gridiron of a cylinder (1), and an end is an arc surface, and the centre has one to be shaped as

Shape also exceeds the boss (4) of bottom surface, form groove between base and middle horizontal edge, one jiao of place of two hypotenuse terminations also has a projection that makes progress, and with the bottom surface in same plane, boss (4) periphery is the through hole that is complementary with its shape, there is a long recess at place, boss (4) base, and a wall of groove is the slideway (15) of band breach (14), breach (14) width and eye-splice (5) width coupling.

Snap close (7) is made by the steel band shell fragment

Shape is complementary with boss (4) shape on the lock (2), and there is a downward elbow (13) its two hypotenuses termination.

At first snap close (7) is embedded in the groove on lock (2), the boss (4), and with the elbow (13) of its end on one side bag be attached on the termination of boss (4), in addition the limit is close on the projection on one angle of termination, cover locking closure (3) at last, eye-splice (5) on it is inserted in lock (2) boss (4) the top through hole slide opening (6), groove on it (8) cooperates with slideway (15), and the locating piece (9) in the groove (8) is cooperated with breach (14) on the slideway (15), connect into the cutter lock of whole cutter.

Blade (11) is buckled on the cylinder (1) of lock (2), puts into the tool rest (10) that cutter band tooth is buckled (12), as shown in Figure 6.

During use, push away locking closure (3) downwards with hand, at this moment the eye-splice (5) on the locking closure (3) is moved to front or rear in the preceding slide opening (6) of boss (4), and press the hypotenuse of snap close (7) and boss (4), it is more tilted, locating piece (9) on the locking closure (3) can only move in breach (14) scope on the slideway (15) simultaneously, thereby the angle of inclination of control snap close (7) and boss (4), allow the elbow (13) of its end and the tooth button (12) that projection is lower than tool rest (10) edge, be not subjected to stopping of tooth button (12) and drive blade (11) to front or rear mobile, stretch out or the tool rest of withdrawing (10) up to blade (11), unclamp hand during to needed position, at this moment snap close (7) sets back under the elastic force effect, imbeds location in the tooth button (12) again, blade (11) can not become flexible, drop out, play the effect that is locked.

Claims (3)

1. the cutter of cutter lock, by locking closure (3), lock (2) and on locking, mobile device connect into whole institute and form, it is characterized in that described locking, mobile device for to be connected, and the snap close (7) that cooperates with locking closure (3) with lock (2).
