Starting the electric slide 9 drives the slider 10 to slide, and then the placement frame 3 moves synchronously, which is convenient for pushing the limited rod forward and cutting it.

[0036] In this embodiment, the quantitative component includes a material discharge box 12 fixedly installed on the top of the workbench 1, a first material guide plate 13 and a second material guide plate 17 fixedly installed inside the material discharge box 12, a feeding barrel is installed on the top of the material discharge box 12, and a material discharge hole is opened at the bottom of the material discharge box 12.
