Technical Field

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

Background

The PCB board is when broken, utilizes broken blade on the breaker and PCB board contact to carry out the breakage to it, all utilizes the cutting edge on the blade to carry out the breakage to the PCB board, if the PCB board when the handle of a knife end contact on long-time and the blade, can strike the end of handle of a knife, because the crushing ability of handle of a knife does not basically have, so easily lead to rocking and damaging of handle of a knife, make the security of cutting edge reduce, security when the broken PCB board of influence cutting edge.

Disclosure of Invention

The invention aims to provide a high-safety blade for crushing a PCB (printed circuit board), so as to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a high blade of security that PCB board was broken was used, 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 the equidistance distributes on the handle of a knife, the mounting hole is the slotted hole shape.

Preferably, both sides of the top of the cutting edge are provided with fastening strips, and one side of each fastening strip is fixedly connected with the corresponding cutter handle.

Preferably, the fastening strip is formed by fixedly connecting a plurality of semicircular convex blocks.

Preferably, the other side of the knife handle is fixedly clamped with two locking plates.

Preferably, the two ends of the knife handle are provided with arc-shaped grooves.

The invention has the technical effects and advantages that:

according to the invention, the PCB is crushed by the cutting edge, the contact area between the PCB and the two ends of the knife handle is reduced by the arc-shaped grooves at the two ends of the knife handle, the stability and the safety of the knife handle during working are ensured, and the phenomenon that the knife handle shakes due to the impact of the PCB when working to influence the normal work of the blade is prevented.

Drawings

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

In the figure: 1. a knife handle; 2. a blade; 3. fastening strips; 4. mounting holes; 5. a locking plate; 6. an arc-shaped groove.

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 high-safety blade for crushing a PCB (printed circuit board), which is shown in figure 1 and comprises a blade handle 1, wherein a blade 2 is fixedly arranged on one side of the blade handle 1, mounting holes 4 are formed in the blade handle 1 and are distributed at equal intervals, and the mounting holes 4 are in the shape of long round holes.

Both sides of the top of the cutting edge 2 are provided with fastening strips 3, and one side of each fastening strip 3 is fixedly connected with the knife handle 1.

The fastening strip 3 is formed by fixedly connecting a plurality of semicircular convex blocks.

Two locking plates 5 are fixedly clamped at the other side of the knife handle 1.

Arc-shaped grooves 6 are formed at two ends of the knife handle 1.

This practical theory of operation:

during the operation, utilize cutting edge 2 to carry out the breakage to the PCB board, when the PCB board strikes the both ends of handle of a knife 1, area of contact when the arc 6 at handle of a knife 1 both ends reduces PCB board and handle of a knife 1 contact reduces the impact of handle of a knife 1, guarantees the stability of handle of a knife 1 during operation, guarantees the security of cutting edge 2 during operation, makes cutting edge 2 work normally.

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.
