Abstract:
1. A paint bullet gun comprising: a barrel; a handle; a bolt and a strike-controlling unit are disposed in the barrel; a valve body and an arrestor being disposed in the handle, the arrestor being adjacent to the valve body for driving the valve body; an air source being arranged under the barrel for supplying air into the barrel and the valve body to control the valve body and the strike-controlling unit, the strike-controlling unit serving to control the bolt to reciprocally move for dropping a paint bullet and shooting the paint bullet with the air of the air source; the valve body has a linking section and an arresting section, the linking section being formed with a tunnel, a linking member and a spring being sequentially mounted in the tunnel in a direction to an opening of the barrel; the arresting section is formed with a passage communicating with the tunnel via a ventiduct, the passage communicating with the air source via an intake, the middle of an inner wall face of the passage being formed with an annular groove corresponding to the intake, the annular groove having a trapezoidal cross-section with slopes, whereby the air can go from the air source into the passage; a shaft and a resilient member are accommodated in the passage, one end of the shaft contacting with the arrestor, the other end of the shaft being pushed by the resilient member, via a relief duct, the ventiduct communicating with a part of the passage, in which part the resilient member is accommodated, the arresting section being formed with an escape hole opposite to the relief duct, the escape hole communicating with the part of the passage, in which part the resilient member is accommodated, the diameters of the relief duct and the escape hole being smaller than the diameters of the ventiduct and the passage; and the shaft is formed with a first annular groove, when the shaft is reciprocally moved, the first annular groove being moved to a position corresponding to the ventiduct or moved away from the position corresponding to the ventiduct so as to switch a communication state and discommunication state between the first annular groove and the annular groove of the passage.
