The mounting seat slides along the length direction of the support rod, the glue injection head slides along the height direction of the support, the feeding port of the glue injection head is connected with a glue injection pipe, and a feeding tank for injecting glue into the glue injection pipe is arranged on the side wall of the support. The side wall of the support is provided with a first driving member for driving the support rod to slide, the side wall of the support is provided with a second driving member for driving the mounting seat to slide, and the mounting seat is provided with a third driving member for driving the glue injection head to slide.

[0004] The support rod of the above dispensing machine drives the glue injection pipe to move in the length direction of the support. When the support rod moves away from the feeding tank, the distance between the glue injection pipe and the operation table is large.
