[0047] At the same time, the support rod 802 is driven to slide on the round rod 21 through the slide 801, so that the shield 805 fixed at the front end of the connecting rod 804 can drive the cutting wheel 808 to move, and the position of the cutting wheel 808 can be adjusted. At the same time, there is a handle 810 at the top of the shield 805. The handle 810 provides a convenient operation method for the user. The user can easily control the cutting equipment by holding the handle 810 to complete various cutting tasks. The rotating connection design between the cutting wheel 808 and the shield 805 allows the cutting wheel 808 to rotate freely inside the shield 805, which not only facilitates the operation of the cutting process, but also ensures the safety performance of the cutting equipment.
