[0019] In order to improve the convenience of cutting, refer to Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 1, a support plate 2, a rotating component, a cutting component and a limiting component. The cutting component and the limiting component are both arranged on the support plate 2. The limiting component positions the building workpiece to be cut within the cutting range of the cutting component. The support plate 2 is arranged on the base 1 through the rotating component. The cutting component is rotated according to the cutting direction of the workpiece, and the building workpiece to be cut is placed on the support plate 2. The screw 10 is rotated, and the sliding rod 13 slides in the sliding groove 12 to convert the rotational motion into linear motion, so that the clamping seat 11 moves toward the abutment plate 14, and the building workpiece to be cut is limited and fixed, thereby improving the stability during the cutting process. When the cutting direction needs to be changed, the support plate 2 is pushed, and the ball 19 rolls in the sliding rail 18 to drive the support plate 2 to rotate, so that the cutting direction of the cutting component also follows the rotation, so that it rotates to the side where the staff is, which can avoid the staff from following and walking.

[0020] In order to facilitate the fixing of the building workpiece to be cut, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the support plate 2 is provided with a support frame 3, and the cutting assembly includes a motor 4 provided on the support frame 3, the power output end of the motor 4 is connected to a driving pulley 5, the driving pulley 5 is connected to a driven pulley 7 through a transmission belt 6, a rotating shaft is inserted in the driven pulley 7, and a cutting wheel 8 is connected to the end of the rotating shaft away from the driven pulley 7, the driving pulley 5 is driven to rotate by the power output end of the motor 4, and the driven pulley is driven to rotate by the cooperation of the transmission belt 6, so that the rotating shaft rotates, and the cutting wheel 8 rotates to cut the building workpiece. The limiting assembly includes a fixing plate 9 provided on the base 1, the fixing plate 9 supports the screw 10, and a threaded hole adapted to the screw 10 is provided in the fixing plate 9. The fixing plate 9 is axially inserted with a screw 10, and the end of the screw 10 facing the cutting area is connected to a clamping seat 11, and the end of the screw 10 away from the clamping seat 11 is provided with a handle to facilitate the rotation of the screw 10. The surface of the support plate 2 is provided with a slide groove 12, and a slide rod 13 is inserted into the clamping seat 11. The slide rod 13 passes through the clamping seat 11 and the support plate 2 in sequence and extends into the slide groove 12. When the screw 10 rotates, the slide rod 13 slides along the length direction of the slide groove 12, thereby converting the rotational motion into linear motion, driving the movement of the clamping seat 11, so as to change the size of the limiting area according to the size of the building workpiece to be cut. The limiting assembly also includes an abutment plate 14 arranged on the support plate 2, and the lower surface of the abutment plate 14 is provided with an arc groove 15, and a positioning bolt 16 is inserted into the arc groove 15.

A plurality of screw holes are equidistantly spaced around the surface of the base 1, and bolts are provided on the support plate 2. When the support plate 2 needs to be fixed, the support plate 2 can be fixed by inserting the bolts into the screw holes.
