Glue gun with advancing mechanism for glue stick

摘要

A glue gun having an advancing mechanism which has a longitudinally slidable carriage member with a longitudinal opening for the glue stick is provided. The carriage member has a first transverse opening in communication with the longitudinal opening and a second transverse opening in communication with the first transverse opening which is also transvers to the first transverse opening. The first transverse opening has internal peripheral bearing surfaces. A substantially T-shaped angularly displaceable gripper member is included which has an upper member defining a gripper head and a lower member defining a transverse lever. The gripper head is receivable into the first transverse opening and has a front end, a rear end, an upper end and a gripper tooth near its front and upper ends for gripping the glue stick. The gripper head further has exterior peripheral bearing surfaces near its front and rear ends which slidably bear against the internal peripheral bearing surfaces of the first transverse opening to retain the gripper head in the first transverse opening while permitting angular displacement of the head.
