Technical Field

The invention relates to the field of blades, in particular to a blade for crushing a PCB (printed circuit board).

Background

The PCB board need be broken to it when production, broken blade is fixed basically, need change whole blade when breaking appearing, it is comparatively troublesome, so at present be the detachable blade basically, convenient to detach changes, convenient and fast, common blade both ends are most advanced, when broken with the contact of PCB board, because the most advanced on the great messenger blade of contact resistance is broken or the phenomenon of rupture easily appears, influence the normal use of blade, reduce the life of blade.

Disclosure of Invention

The present invention is directed to a blade for breaking PCB boards, which solves the above problems of the prior art.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a blade for PCB board is broken usefulness, includes the handle of a knife, one side of handle of a knife is fixed and is equipped with the cutting edge, set up the mounting hole that a plurality of equidistance distribute on the handle of a knife.

The mounting hole is in the shape of a long round hole.

The top both sides of cutting edge all are equipped with the fixed plate, one side and the handle of a knife fixed connection of fixed plate.

The arc ends are arranged at the two ends of the cutting edge.

The knife handle is rectangular.

The invention has the technical effects and advantages that:

according to the PCB board crushing device, the two arc-shaped ends arranged on the cutting edge reduce the resistance of the cutting edge when the cutting edge crushes the PCB board, and the crushing efficiency and the crushing quality are ensured.

Drawings

Fig. 1 is a schematic front structural view of the present invention.

In the figure: 1. a knife handle; 2. a blade; 3. an arcuate end; 4. a fixing plate; 5. and (7) installing holes.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a blade for crushing a PCB (printed circuit board) as shown in figure 1, which comprises a cutter handle 1, wherein a cutting edge 2 is fixedly arranged on one side of the cutter handle 1, and a plurality of mounting holes 5 which are distributed at equal intervals are formed in the cutter handle 1.

The mounting hole 5 is in the shape of a long round hole.

Both sides of the top of the cutting edge 2 are provided with fixing plates 4, and one side of each fixing plate 4 is fixedly connected with the cutter handle 1.

Arc-shaped ends 3 are arranged at the two ends of the cutting edge 2.

The tool holder 1 is rectangular.

This practical theory of operation:

during the operation, the arc end on the cutting edge 2 is at first broken with the contact of PCB board, utilizes arc end 3 to reduce the contact resistance of cutting edge 2 and PCB board, guarantees the normal use of cutting edge 2, prolongs the life of cutting edge 2, and convenient and fast utilizes fixed plate 4 to strengthen fixed effect to playing.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
