[0007] A further improvement is that a column is fixedly arranged on the left side of the processing table, and a support beam for installing a cutting machine is fixedly connected to the upper end of the column.

[0008] A further improvement is that a slide rail is arranged from front to back in the middle of the upper surface of the processing table, and the slide seat is slidably arranged on the slide rail.

[0009] A further improvement is that a sliding block matched with the sliding rail is provided on the bottom surface of the sliding seat.

[0010] A further improvement is that one end of the locking bolt passes through the support block for connecting with the shoe last, and the other end of the locking bolt is provided with a bolt handle.

[0011] A further improvement is that a pushing handle is provided at one end of the support block away from the positioning rod.

[0012] Compared with the existing technology, the above technical solution has the following beneficial effects:

[0013] The first guide wheel and the second guide wheel of the saw blade protection assembly can guide the saw blade and provide certain support to the middle part of the saw blade, thereby preventing the saw blade from breaking during the cutting process, better protecting the saw blade and extending its service life. The positioning rod and the clamping bolt can be used to clamp and fix the shoe last conveniently and quickly, and the limit screw can freely adjust the distance from the slide seat as needed, thereby adjusting the depth of the oblique cut.
