[0010] Preferably, a mounting bracket is fixed at a position corresponding to the outer wall of the protective cover and the connecting pipe, and a horizontally placed hydraulic telescopic rod is installed on the mounting bracket. A pipe joint is installed at one end of the hydraulic telescopic rod, one end of the pipe joint is connected to the horizontal part of the connecting pipe, and the other end of the pipe joint is connected to a connecting hose.

[0011] Preferably, a dust box is installed above the mounting plate, the top end of the dust box is opened, the opening cross section of the dust box is larger than the through-opening cross section, and the inner wall of the protective belt is in sliding contact with the outer wall of the top of the dust box.

During the process of switching back and forth between the hole and the protective cloth, the outer edge of the hole and the protective cloth slide and rub against the outer wall of the protective cover to clean the dust or liquid adhered to the surface. During the tool changing process, the protective cloth used for protection and shielding is kept away from the tool changing position, so as to avoid the protective cloth always being at the tool changing position and being adhered to dust or liquid for a long time, affecting the subsequent processing operations and the long-term use effect of the tool magazine.

[0018] In the present invention, when the protective cloth is used to shield and protect the knife-changing edge position, each connecting pipe is used to suck air at the knife-changing edge position to suck and clean the dust or liquid stains at the knife-changing edge position, thereby further improving the dust and liquid prevention effect of the knife-changing edge position, thereby improving the effectiveness of the long-term use of the tool magazine structure.

[0019] In the present invention, the inner wall of the protection belt facing the blade changing port is cleaned by the rotating and swinging cleaning brush cylinder, and the dust collecting box above and the connecting pipe below are cooperated to improve the dust and liquid proof effect of long-term use.
