Abstract
A staple gun with a latch assembly has a housing, a handle, a pivot pin, a spring, a staple driver and a staple magazine. The housing has two half-casings and a handle opening. The half-casings are symmetrical and connected to each other, and each half-casing has a latch tab. The latch tab is formed on and protrudes in from the half-casing. The handle is connected pivotally to the housing through the handle opening and has an inner end and a latch clip. The inner end extends into the housing between the half-casings and has two sides and two mounting slots formed respectively in the sides of the inner end and aligning with each other. The latch clip is mounted in and protrudes through the mounting slots to selectively engage the latch tabs and hold the handle in place.
