Abstract
A cutting device for a metal band bundling apparatus includes a band guider, a rotatable knife fitted in a hole of the band guider fixed on a first handle of a metal band bundling apparatus, and a press rod connected with the knife. The press rod consists of a bent portion and a press portion, and the bent portion located to pass across over the first handle and a second handle. A user can hold the grip portions of the first and the second handle with four fingers of a hand and presses the press portion with the thumb of the hand to rotate the rod-shaped knife for a certain angle to cut off a metal band. So cutting operation can be preformed with the thumb of a hand only, very easy and quick to operate after bundling an object with the metal band.
Claims1
A cutting device for a metal band bundling apparatus, said metal band bundling apparatus having a first handle and a second handle, said first and said second handle respectively provided with a grip portion forming an acute angle to each other, said cutting device comprising:
- a band guider fixed on a front side of an upper end of said first handle and a tightening unit fixed on a front side of an upper end of said second handle;
- said band guider provided with an aperture for a metal band to pass through., and a hole bored laterally at a front side of said aperture;
- a knife of a rod shape fitted rotatively in said hole of said band guider and having a blade facing to said aperture;
- a press rod having an upper end connected in a right angle with a rear end of said knife, and a bent portion of a certain length passing over said first handle and said second handle to reach near said grip of said second handle, a pushing portion extending bent from a rear end of said bent portion for the thumb of a hand of a user to press while the other four fingers are holding said grip portions of said first and said second handle, said knife rotated for a certain angle to cut off the metal band when said press portion is pressed by only the thumb of one hand of the user;
- and
- a spring having a first end fixed on the upper end of said first handle, and a second end fixed on said press rod near said knife, pushing back said press rod elastically to its original position after pressed,
