A pushing device, a stabilization rack and a power device are arranged on the support, wherein the pushing device is used for pushing rod wax to move to be in friction with a cloth roller, the stabilization rack is used for keeping the rod wax stable, and the power device is used for driving the pushing device and the stabilization rack to be mutually matched. The stabilization rack is connected with the power device through a positioning mechanism and the power device drives the stabilization rack and the rod wax to move in the same direction. The special pushing device is used for fixing the rod wax and making the rod wax continuously be in contact with or abut against the cloth roller, the special stabilization rack is arranged for the rod wax, the rod wax is protected in a reinforced mode and is not prone to breakage, and it is required that the stabilization rack protects the rod wax and cannot block normal movement of the rod wax. When the cloth roller and the rod wax are consumed and shortened, both the rod wax and the stabilization rack move downwards, and it is guaranteed that only a small section of the rod wax is exposed out of the stabilization rack. Thus, the stabilization rack and the pushing device are kept to move in the same direction.
