The handle 201 and the machine body 1 are respectively held by two hands of an operator, the machine head 3 is controlled to work, the machine head 3 works, the spindle part of the machine head 3 can drive the cutter disc 6 to rotate, the cutter disc 6 can rotate rapidly, and the operator can cut the workpiece after moving the cutter disc 6 to the position where the workpiece and the like need to be cut.
The protection process comprises the following steps:
When cutting is finished, the cutterhead 6 is stopped, the cutterhead 6 can be continuously rotated under the action of inertia, an operator pulls the sliding block 901 downwards, the sliding block 901 is separated from the magnetic force range of the magnet 904 (the sliding block 901 can be made of materials such as iron and the like and can be attracted by the magnet 904), the sliding block 901 moves to the position where the lower end is attached to the upper end of the round block 902, meanwhile, the sliding block 901 can drive the sleeve block 804 to synchronously move through the straight rod 805, the sleeve block 804 can drive the rotary plate 905 to downwards move, the rotary plate 905 can be pulled by the sleeve block 804, the operator pulls the rotary plate 905, enables the rotary plate 905 to overturn 180 degrees, enables the protective cover 7 to move to the position right below the cutterhead 6, pushes the rotary plate 905 upwards, enables the sliding block 901 to be magnetically connected with the magnetic block 904 again, meanwhile, the protective cover 7 can be sleeved to the outer side of the cutterhead 6, the continuously rotating cutterhead 6 is prevented from injuring the operator, the rotary plate rotates to the position where the square block 10 abuts against the other side, the rotary plate 804 can drive the rod 801 to move downwards, the rotary plate 905 can move downwards through the sleeve block 804, the rotary plate 905 can be pulled by the sleeve block 804 to stretch the spring 802, the rotary plate 905 can be pulled upwards when the rotary plate 905 is required to rotate, and the rotary plate 905 can be pulled upwards, the rotary plate 905 can be opened upwards, and the rotary plate can be opened, and the rotary plate can be pulled upwards against the position of the rotary plate 905 can be rotated upwards, and the rotary plate can be opened.
While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the scope of the invention.
