[0007] The front end of the tool holder is connected to the central screw through a screw hole. The central screw is rotatably connected to the V-shaped tool head. Both the upper and lower ends of the tool head are provided with sliding grooves. The end of the oblique blade is slidably connected in the sliding groove. The tool holder is rotatably connected to the middle rear side of the oblique blade. The end of the oblique blade is rotatably connected to the positioning rod. The positioning rod is inserted into the hole of the tool head. The positioning bolt is pressed on the positioning rod for fixation.

[0008] Preferably, the outer end of the extrusion wheel is a conical disc, which concentrates the sponge on both sides to the middle, making it convenient for later cutting.

[0009] Preferably, the central screw has a hexagonal nut in the middle for easy rotation with tools.

[0010] Preferably, the tool holder consists of a horizontal bar and several diagonal braces for stable transmission.

[0011] Preferably, both sides of the slider are rotatably connected to rolling rings, which slide within the guide groove of the drive assembly to reduce friction.

[0012] Preferably, the drive assembly is a pneumatic telescopic rod or an electric telescopic rod, which performs linear transmission.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a drive assembly to move a slider, which in turn moves a linkage rod to move a blade holder and an extrusion frame. The height is adjusted by bolts. When the extrusion wheel moves, it positions and extrudes the sponge, facilitating subsequent cutting.

[0015] 2. In this utility model, during cutting, the blade first separates the sponge, and then the oblique blade makes the final cut, reducing the resistance during cutting. When it is necessary to cut sponges of different thicknesses, the central screw is rotated to move the blade holder and adjust the position of the oblique blade end. Finally, the positioning bolt is rotated to fix the position of the positioning rod, thus fixing the oblique blade and changing the cutting thickness. Attached Figure Description
