[0030] like Figure 2 , 3 As shown in Figures 13, the main body of the movable rod 7 is a screw rod 701, one end of which passes through the box body 1 and the placement tube 2 and is located inside the placement tube 2, and the end of the screw rod 701 located inside the placement tube 2 is fixed with a fixing plate 703, and the other end of the screw rod 701 extends out of the box body 1 and is provided with a limiting block 702; a motor 8 is also provided in the box body 1, and a first gear 9 is fixed to the output end of the motor 8, and the first gear 9 and the intermediate gear set 10 are engaged for transmission, and the intermediate gear set 10 is connected to the screw rod 701 to drive the screw rod 701.

[0031] Before normal use, put the glue stick into the placement tube 2, and then rotate and install the glue outlet 3. When in use, the operator starts the switch 6, and the motor 8 drives the screw rod 701 to move through the first gear 9 and the intermediate gear set 10. During this process, the screw rod 701 drives the fixing plate 703 to provide extrusion force to the glue stick, so that the glue is squeezed out from the glue outlet 3. When the glue stick is squeezed to the end, the limiting block 702 contacts the box body 1, limiting the movement range of the screw rod 701 and improving safety.
