Adapter to connect water pipe and high-pressure spray gun

An adapter for connecting a water pipe and a high-pressure spray gun, the adapter comprising:

• a connection assembly having:
• a connector body defined by a side wall and extending between a proximal end and a distal end, wherein the water pipe is adapted to be coupled along the proximal end and the high-pressure spray gun is adapted to be coupled along the distal end,
• a chute extending along the connection body between the proximal and distal ends, the chute having:
• grooves on the side wall of the connector body, and
• tapered regions seamlessly extend below from the grooves on the side wall;
• a clamping assembly operatively coupled to the connector body, the clamping assembly having:
• a buckle;
• and
• a fixing structure extends outwardly from the side wall,
• wherein the buckle clamps with the chute, the buckle having:
• a top portion movably engaged with the grooves and passes through the chute along the proximal end,
• a middle portion extends along the side wall of the connector body between the proximal and distal ends, and
• a bottom portion moveably engages with the fixing structure along the distal end;
• and
• a covering member sleeves over the connection assembly to movably engage with the clamping assembly,
• wherein the covering member is pressed to realise the buckle to move down from the grooves towards the tapered regions to accommodate the water pipe in the chute, and
• wherein the covering member is released to realise the buckle to move back into the grooves from the tapered regions to clamp the water pipe in the chute.
