## Abstract

A water discharge controlling structure of a sprinkling gun, in which a controlling bolt is slidably disposed in a barrel of the sprinkling gun and a nut is screwed with a rear end of the controlling bolt. The barrel has a rear end formed with two lateral axial shallow channels and two lateral arms of the U-shaped pushing plate are slidably received in the shallow channels. The pushing plate has a middle bridge portion formed with a key hole-shaped driving hole through which the controlling bolt is passed. The nut has a narrowed neck portion chucked in the key hole-shaped driving hole of the pushing plate. Each lateral arm has a free end formed with an outward bent engaging plate. A pivot seat is disposed on upper face of the barrel for pivotally connecting with two upward extending lugs of the trigger. Each lug is formed with an engaging slot for the engaging plate of the lateral arm of the pushing plate to engage therein. When operated, the trigger is pulled to urge the pushing plate to slide back and forth along the axial shallow channels of the barrel and a peripheral wall of the driving hole of the pushing plate drives the nut so as to slide the controlling bolt back and forth within the barrel without swinging the barrel for stably controlling the water flow.

## Claims

### Claim 1

A water discharge controlling structure of a sprinkling gun, in which a controlling bolt is slidably disposed in a barrel of the sprinkling gun and a nut with narrowed neck portion is screwed with a rear end of the controlling bolt, said controlling structure being characterized in that:
the barrel has a rear end formed with two lateral axial shallow channels and two lateral arms of the U-shaped pushing plate are slidably received in the shallow channels, the pushing plate having a middle bridge portion formed with a key hole-shaped driving hole through which the controlling bolt is passed, the narrowed neck portion of the nut being chucked in the driving hole of the pushing plate, each lateral arm having a free end formed with an outward bent engaging plate, a pivot seat being disposed on upper face of the barrel for pivotally connecting with two upward extending lugs of the trigger, each lug being formed with an engaging slot for the engaging plate of the lateral arm of the pushing plate to engage therein, whereby when operated, the trigger is pulled to urge the pushing plate to slide back and forth along the axial shallow channels of the barrel and a peripheral wall of the driving hole of the pushing plate drives the nut so as to slide the controlling bolt back and forth within the barrel for controlling the water flow.
