Abstract

A multi-functional engineering clipper comprises a cutting portion and a handle portion; a plurality of screwing units for fixing the cutting portion with the handle portion; two pivotal portions being installed on the cutting portion; a front end of each pivotal portion being installed with a first knife portion; each first knife portion having a flat knife; the two flat knives being symmetrically arranged; a rear end of each pivotal portion being installed with a second knife portion; each second knife portion having a semi-round knife; the two semi-round knives being symmetrically arranged; and a rear end of each second knife portion being extended with a third knife portion; each third knife portion having a cambered knife. Thus, the multi-functional engineering clipper can be used to cut steel plates, steel strips, nails, rivets, cables, iron strips, cables, etc.

Claims

1. A multi-functional engineering clipper comprising:

a cutting portion and a handle portion;

a plurality of screwing units for fixing the cutting portion with the handle portion;

two pivotal portions being installed on the cutting portion;

a front end of each pivotal portion being installed with a first knife portion;

each first knife portion having a flat knife;

the two flat knives being symmetrically arranged;

a rear end of each pivotal portion being installed with a second knife portion;

each second knife portion having a semi-round knife;

the two semi-round knives being symmetrically arranged; and

a rear end of each second knife portion being extended with a third knife portion;

each third knife portion having a cambered knife.

2. The multi-functional engineering clipper as claimed in claim 1, wherein the first knife portion serves for cutting one of steel plates and steel strips.

3. The multi-functional engineering clipper as claimed in claim 1, wherein the second knife portion serves for cutting cables.

4. The multi-functional engineering clipper as claimed in claim 1, wherein the third knife portion serves for cutting one of steel ropes and steel ropes.

5. A multi-functional engineering clipper comprising:

a cutting portion and a handle portion;

the cutting portion having two pivotal portions;

a front end of each pivotal portion being installed with two first knife portions;

each first knife portion having a flat knife;

the two flat knives being symmetrically arranged;

a rear end of each first knife portion being extended with a second knife portion;

each second knife portion having a semi-round knife;

the two semi-round knives being symmetrically arranged; and

a rear end of each second knife portion being extended with a third knife portion;

each third knife portion having a cambered knife;

a rear end of each third knife portion being extended with a leg;

wherein the handle portion is formed by two handles;

each handle has an approximately U shape recess for receiving a respective one of the legs of the cutting portion;

two lateral sides of each handle are approximately parallel and two lateral sides of each leg are approximately parallel;

each handle being locked to the respective leg by using screws to pass through the handle and the leg from the lateral sides of the handle and the leg;

wherein the first knife portion serves for cutting one of steel plates and steel strips;

wherein the second knife portion serves for cutting cables; and

wherein the third knife portion serves for cutting steel ropes.

6. The multi-functional engineering clipper as claimed in claim 5, wherein a lower portion of the cutting portion is thicker than an upper portion of the cutting portion so as to provide a firm structure at the connection of the cutting portions and the handle portion.
