The invention provides a supporting device with the convertible angle for spinning, and relates to the field of spinning. The supporting device comprises a base. A shell is fixedly installed at the top of the base. A rod body is alternately arranged at the top of the shell, the end, close to the shell, of the rod body penetrates through the top of the shell and extends into the shell, and a box isalternately arranged at the top of the rod body. According to the supporting device with the convertible angle for spinning, by arranging a sliding groove, a sliding plate, a clamping block, a motor,a lead screw and a reset spring, the effect of adjusting the angle of the supporting device for spinning is achieved, and therefore a user can conveniently use the device; the working efficiency of the supporting device for spinning is improved, the using efficiency of the supporting device for spinning is improved, and therefore the normal use of the supporting device for spinning is convenient,and therefore the working efficiency of spinning workers is improved.
