One end of the feeding pipe is connected to the gun head 3, and the other end of the feeding pipe is bent and stored through the material storage mechanism 11, thereby reducing the space occupied by the feeding pipe; the material storage mechanism 11 includes a box body 11, a plurality of first guide wheels 12 and a drag chain 13 staggered in the box body 11; the base 4 is arranged at the lower part of one side of the box body 11, and the base 4 is fixedly connected to the box body 11, forming an integrated module design as a whole, which is convenient for overall movement; the feeding pipe is arranged in the drag chain 13, and the surface of the drag chain 13 is provided with a first rack 131, and the first rack 131 is a flexible rack that can be bent appropriately, The drag chain 13 bypasses the first guide wheel 12 in sequence, and the first guide wheel 12 is meshed with the first rack 131; the drag chain 13 can not only protect the feeding tube, but also drive the feeding tube through the movement of the drag chain 13. The spacing between the two offset first guide wheels 12 can be adjusted. The longer the feeding tube stored in the box 11, the larger the spacing between the two offset first guide wheels 12, and vice versa; the first guide wheel 12 can be powered or unpowered. When the first guide wheel 12 is powered, it needs to cooperate with the telescopic mechanism 2 so that the movement of the gun head 3 and the movement of the drag chain 13 are synchronized.
