Description

Belt cut

The present invention relates to a band shear, and more particularly to a cutting tool for cutting a remaining body after the band is tightened.

As shown in Figures 8 to 9, for the conventional belt cutter, the handle 91 and the handle 92 are pivotally connected, and the two handles 91, 92 are relatively swingable, and the handle 91 has a through hole 911 at the front end for the belt to pass through. The handle 92 also has a brake block 921 at the front end. The brake block 921 can block the teeth on one side of the strap when the strap passes through the through hole 911, and can pull the strap to tighten the object. The handle 91 has a cutter 93 disposed on the bottom plate 912. The handle 94 is pivotally connected to the handle 91 and coupled to the cutter 93. The cutter 93 is interlocked by the handle 94 and is relatively displaced on the bottom plate 912 and the blade 931 is passed through the through hole 911. It is possible to cut off the portion of the belt that is exposed when the object is tightened.

In order to enable the cutter 93 to be translated on the bottom plate 912 without lifting, the conventional belt cutter has a long hole 932 in the cutter 93, and a perforation 913 corresponding to the long hole 932 in the bottom plate 912. After passing through the perforation 913 and the long hole 932, the nut 96 is padded with a nut 96 on the cutter 93, and is rotated in the direction of the anti-songhua 97 to the anti-songhua 97 to the cutter 93. To ensure that the cutter 93 is attached to the bottom plate 912 for displacement. However, this conventional band cutter has the following problems:

1. The conventional band cutter, in order to enable the cutter 93 to be attached to the bottom plate 912, a long hole 932 must be formed on the cutter 93, and a hole 913 must be formed on the bottom plate 912, and the bolt is passed through and long. The perforations 913 aligned with the holes 932 are then locked with the nuts 96 of the anti-songs 97. As a result of the cumbersome process, the cutters 93 have a problem of difficulty in assembly on the bottom plate 912.

2, in the 1, the cutter 93 will be attached to the bottom plate 912 displacement, mainly caused by the nut 96 through the anti-Song Huashi 97 force on the cutter 93, if the degree of the lock of the nut 96 is too tight, may cause The cutter 93 has a situation in which the displacement is not smooth; the degree of the lock of the nut 96 is too loose, and the cutter 93 has a situation in which it cannot be attached to the bottom plate 912. Usually, it must be tested after several times to confirm that it is the best, so that It is also inconvenient to adjust the position of the anti-Songhua 97 to the cutter 93 by the rotation of the nut 96.

3. In order to smoothly cut the belt, the displacement of the cutter 93 on the bottom plate 912 must be smooth, but the long hole 932 is set on the cutter 93, and the hole 913 is arranged on the bottom plate 912, which is easy to be processed at the edge of the hole. If the waste is not cleaned, the cutter 93 is displaced on the bottom plate 912, and there is a resistance caused by the friction of the scrap, which causes a problem that the cutter 93 is not smoothly displaced on the bottom plate 912.

Therefore, how to solve the problem of the above-mentioned conventional belt cutting is the focus of this creation.
