[0022] During use, after the workpiece is installed on the claw plate 2, the safety shield plate 4 is rotated with the help of the handle fixed on the outer wall of the safety shield plate 4. During the process, the damping telescopic rod 10 is compressed until the fixed plate 7 is engaged with the safety shield plate 4. At this time, the position of the damping telescopic rod 10 is horizontal. After that, after the position of the safety shield plate 4 is fixed, the processing device on the machine tool body 1 moves to the processing position and cooperates with the claw plate 2 to rotate to process the workpiece. At this time, the L-shaped frame plate 3 and the safety shield plate 4 cover the side of the workpiece to prevent processing debris from splashing and injuring people. The processing status of the workpiece can be observed in real time through the glass plate 5.

[0023] Example 2: On the basis of Example 1, the fixed columns 11 in the limit assembly are symmetrically fixed on the two side walls of the safety protection cover plate 4, and the rotating plate 12 is symmetrically rotatably arranged on the two side walls of the L-shaped frame plate 3, and a card slot 13 is provided on the side end of the rotating plate 12; the mounting hole 14 is provided on the fixed plate 7, and the end of the latch 15 is fixedly provided with a limit plate 16, and the V-shaped plate 17 is fixedly provided at the upper end of the L-shaped frame plate 3; the fixing column 11 corresponds to the setting position of the card slot 13 and is set in the same number of groups, the fixing column 11 is snapped into the card slot 13, and a driving rod is fixedly provided at the end of the rotating plate 12; the mounting hole 14 corresponds to the setting position of the latch 15 and is set in the same number of groups, and the two are plugged in; the limit plate 16 is snapped with the safety protection cover plate 4, and the side wall of the limit plate 16 is fixedly provided with a pull ring, and the V-shaped plate 17 is snapped with the safety protection cover plate 4.

[0024] When in use, the workpiece is installed on the claw disk 2, and after the safety protection cover plate 4 is rotated to engage with the fixed plate 7, the rotating plate 12 is rotated with the help of the shift rod so that the fixed column 11 is engaged with the slot 13 to play a limiting role, thereby preventing the damping telescopic rod 10 from pushing and lifting the safety protection cover plate 4 during the machining of the workpiece; after the workpiece is processed, the rotating plate 12 is rotated to separate the fixed column 11 from the slot 13, and the safety protection cover plate 4 is lifted up with the help of the handle. During the process, the damping telescopic rod 10 resets and rebounds to assist the safety protection cover plate 4 to be lifted up until the safety protection cover plate 4 rests against the safety protection cover plate 4. At this time, the damping telescopic rod 10 plays a certain supporting role, and then the pin 15 is inserted into the mounting hole 14 so that the limit plate 16 is engaged with the safety protection cover plate 4, thereby preventing the safety protection cover plate 4 from falling off easily and injuring the operator after being lifted up.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
