Abstract
An improved dispensing syringe for a fluid glue, which comprises a syringe stem, a syringe seat, a syringe cap, a guide sleeve and a sealing pad; the syringe seat has a conic cylindrical opening at one end, and a contact surface and a guide hole on the other end thereof; one end of the syringe stem has a bevel opening, being mounted in the center of the conic cylinder opening while the other end thereof is a flat opening, being set out of the syringe seat.
