Preferably, the side wall of the annular clamping sleeve is provided with a plurality of shrinkage joints;

the contraction joint penetrates through the side wall of the annular clamping sleeve and extends in the direction away from the pressure gauge body in parallel with the axis of the tubular cavity of the buckle until the opening is formed in the end part of the buckle.

Preferably, the device further comprises a sleeve, and the sleeve is sleeved on the periphery of the buckle.

Preferably, the shape of the buckle is frustum-shaped, the outer diameter of the buckle is gradually increased along the axis of the tubular cavity in the direction far away from the pressure gauge body, the inner diameter of the sleeve is kept unchanged, and the inner diameter of the sleeve is smaller than the outer diameter of the annular clamping sleeve;

when the sleeve is not screwed down, one annular end of the sleeve is sleeved on the outer side of the water inlet pipe, when the sleeve is screwed down, the sleeve gradually brings all the buckles into the sleeve, and the inner side wall of the sleeve gradually presses the annular clamping sleeve to contract inwards so as to clamp the contraction part of the water pipe clamping head;

during the installation, go into the bayonet socket with water pipe dop card, can rotate the orientation of manometer body in order to adjust the manometer dial plate this moment, screw up the sleeve after the adjustment, make firm and water piping connection of manometer.

Preferably, the outer wall of the catch and the inner wall of the sleeve have corresponding threads.

The utility model has the advantages that: a buckle type pressure gauge comprises a circular pressure gauge body, wherein a section of water inlet pipe radially extends out of the pressure gauge body, and a buckle used for being connected and fixed with a water pipe is arranged at the tail end of the water inlet pipe; the buckle can be connected with the dop of installing in advance on the water pipe to rotation adjustment manometer dial plate orientation that can be convenient.
