Claims

[Scope of utility model registration request]

A fitting part that tightly fits into the inner periphery of the injection cylinder is formed at the front end,
At the front end, a claw portion that engages with the outer periphery of the injection cylinder is attached to the side surface of the connecting device main body, which has a supply hole transparent from the inlet port on the outer circumferential surface to which the fluid supply hole is connected to the outlet port on the end surface of the fitting portion. A locking lever formed inside the rear end and having a jaw portion formed inside the rear end is pivotally supported, and a rocking force for expanding the front end portion outward is applied to the locking lever, and An operating body is fitted to the rear end of the main body, and is provided with a valve body that can freely slide in two positions, a front position and a rear position, and applies a backward moving force, and closes the supply hole in the front position. and forming a protrusion on the operating body that engages with the jaw of the locking lever, and in the rear position of the operating body, the inner surface of the jaw comes into contact with the outer surface of the protrusion to engage the locking lever. holding the lever in a position where the claw portion locks onto the outer periphery of the injection barrel against the biasing force;
In the forward position of the operating body, the locking lever is biased so that the claw portion swings in a direction away from the outer periphery of the injection barrel, and the front surface of the jaw portion abuts the rear surface of the protrusion. A connection device for fluid injection, characterized in that the operating body is held in the forward position by the above, and the operating body is pushed rearward by the pressure inside the supply hole.
