摘要： A water spray gun includes a gun body, a handle, a control valve and a retaining cap. The gun body has a water control compartment which is provided with two rotation channels. Each of the rotation channels has two closed ends forming two stop walls. The handle has two connecting arms. Each of the connecting arms is combined with a limit block which includes a root portion mounted in and covered by each of the connecting arms and an operation portion protruding outward from each of the connecting arms. Thus, when the handle is pivoted relative to the gun body, the operation portion of the limit block is moved in each of the rotation channels of the gun body, and is stopped by one of the two stop walls of each of the rotation channels.

摘要： A water spray gun may comprise a main body, a water outlet unit, a spray head and a knob. The main body has a handle and a barrel portion, and interior spaces of the handle and the barrel portion are communicated with each other. A rear end and a front end of the water outlet unit respectively comprise a first connecting portion and a second connecting portion. The spray head is integrally made of plastic material, which simplifies the manufacturing process and lowers the cost, and through communicating the first through hole with the second through holes, the water flow is configured to flow in a straight line thus maintaining the momentum and speed of the water flow to perform different spraying patterns efficiently and to save labors and water.
