When the first spring is disengaged from the constraint, it will release the elastic force to push the extension handle to the right and extend. After the extension handle is fully extended, you can let go of the matching plate, and the third spring rebounds to push the pin into the first positioning slot to tighten the extended extension handle; after the shearing work is ready, place the hardware to the blade position, one foot can step on the pad while pressing the extension handle downward to cut the hardware.

[0007] Furthermore, the bottom end of the third spring is fixedly connected to the upper surface of the matching plate, and the top end of the third spring is fixedly connected to the lower surface of the extension handle.

[0008] Furthermore, a pad is overlapped on the lower surface of the second handle, and the outer surface of the pad is covered with an anti-slip layer.

[0009] Furthermore, a slot is formed on the lower surface of the second handle, a mounting block is mounted inside the slot, and a lower surface of the mounting block is fixedly connected to an upper surface of the pad.

[0010] Furthermore, the number of the first springs is two, and the two first springs are symmetrically arranged about the central axis of the extension handle.

[0011] The present invention provides an adjustable hardware scissors and a method for using the same. The invention has the following beneficial effects:

[0012] The adjustable hardware scissors and the use method thereof can achieve the goal of placing the scissors on the ground for use, which is more labor-saving, by means of the mutual cooperation among the extended handle, the adjustment slot, the first positioning slot, the first spring, the clamping slot, the mounting block, the pad, the anti-slip layer, the second positioning slot, the limit block, the pin shaft, the through hole, the matching plate and the third spring. Meanwhile, by extending the length of the first handle, it is further labor-saving, and it is more efficient and easy to cut thicker hardware, thus solving the problem that the current hardware scissors adopt a conventional structure and the cutting method is exactly the same, and it is difficult to cut thicker hardware.
