Preferably, a plurality of saw teeth distributed perpendicular to the inclined direction are provided on the support inclined surface. When the supporting inclined surface needs to be milled, the sawtooth reduces the material to be milled per unit area, reduces the milling resistance of the milling cutter, and improves the milling efficiency of the milling cutter.

Therefore, the utility model has the beneficial effects that the installation is convenient and the installation angle of the light truck transmission shaft can be adjusted.
