The lower part of the base 1 has a receiving cavity, and a collection member 2 is slidably connected in the receiving cavity. The upper part of the collection member 2 has a collection cavity, and the collection cavity is located below the discharge channel 102. When it is necessary to clean the material debris, the collection member 2 is slid out, and the material debris can be centrally dumped. An insertion groove 101 is provided on the upper part of the base 1, a discharge channel 102 is provided at the corner of the insertion groove 101, and a limiting component 8 is provided in the front part of the insertion groove 101. The limiting component 8 includes a bump 804 fixedly installed on the base 1, a slide rod 803 is fixedly connected to the bump 804, a limiting elastic piece 801 is slidably connected to the slide rod 803, the limiting elastic piece 801 has two arc portions, and the arc portions are in contact with the tab workpiece. A limiting spring 802 is sleeved on the slide rod 803 and in front of the limiting elastic piece 801;

[0023] Move the limiting elastic piece 801 outward, the limiting spring 802 is compressed by the limiting spring 802, place the tab workpiece to be stamped in the insertion groove 101, and then under the action of the limiting spring 802, the tab workpiece is clamped, and the clamping force is appropriate, and the tab is not easily deformed.

[0024] A support frame 4 is fixedly connected to the rear part of the base 1. The longitudinal section shape of the support frame 4 is an inverted L shape.
