Abstract: The invention is related to the structure of an adhesive dispenser that is composed of an outer tube with a push rod and a handle. The apparatus uses a certain number of elastic elements to make relative displacement between push rod and outer tube, while it uses the locking end of the push rod and cotter groove to perform functions like locating, acceleration and stepwise movement, which makes easy operation for the users. Moreover, in the apparatus the outer tube can be equipped with an inner tube. So the spacing between inner tube and outer tube provides a mechanism that the sealant and adhesive filled in-between the inner and outer tube will flow out and mix under the motion of the push rod. This mechanism will not only facilitate sealing, adhesion and hardening prevention, but will also provide reusability.
