Abstract

This article relates to a piston rod for a sealing gun used to apply sealant to joints in building exterior walls. Normally, the teeth of the piston rod move back and forth by the rotation of an electric motor installed inside the holding part of the sealing gun, but to reduce the weight of this piston rod, a horizontal groove is provided along the teeth.
