[0037] The base frame 305 is located between the upper and lower mounting clamps 304. When the rotating assembly 302 rotates, the front head 303 is driven to rotate. After the head 303 rotates, the mounting clamps 304 at the front part of the head 303 are driven to rotate. Finally, the base frame 305 is driven to rotate after the mounting clamps 304 rotate.

[0038] The threaded mounting holes 308 are distributed at equal intervals on the edges of the base frame 305. The distance between the adjacent two mounting bars 306 can be adjusted by the stud bolts. The rotating positioning assembly 3 can adjust the distance between the internal parts according to the width of the wood board 1. When the stud bolts passing through the threaded mounting holes 308 are connected with the mounting bars 306, they are connected with the positioning notches 307 in the mounting bars 306.

[0039] Because the positioning slot 307 is long strip shape, can be according to the length of the wood board 1, adjust the installation strip 306 is located in the base layer frame 305 length, facilitate the rotation positioning assembly 3 inside other parts can more stably hold different size wood board 1.
