Further, an angle locking assembly is arranged on the hinge and comprises a first clamping hook for fixing the opening form of the hinge and a first clamping block matched with the first clamping hook; the second clamping hook is used for fixing the closing form of the hinge, and the second clamping block is matched with the second clamping hook; the angle locking components are arranged at two sides of the hinge.

Further, a sucking disc is arranged on one side of the grid plate, which faces the air port.

Further, the handle is a telescopic rod and is provided with a plurality of sections of telescopic parts.

The utility model has the positive effects that: (1) The grid plate and the handle are rotationally connected, so that the grid plate can reach the air pipe at the high position.

(2) The rotating piece is a hinge, one end of the hinge is clamped on the grid plate, and the other end of the hinge is fixedly connected with the handle, so that the grid plate can rotate towards all directions.

(3) The hinge and the grid plate are magnetically clamped together, so that the replacement and maintenance of the grid plate in the later period are convenient.

(4) The hinge is provided with an angle locking assembly, and the angle locking assembly comprises a first clamping hook for fixing the opening form of the hinge and a first clamping block matched with the first clamping hook; the second clamping hook is used for fixing the closing form of the hinge, and the second clamping block is matched with the second clamping hook; the grid plate is ensured not to shake when in use.

(5) The sucker is arranged on one side of the grid plate opposite to the air port, so that the utility model is more labor-saving when in use, and meanwhile, the grid plate can be temporarily fixed outside the air port and cannot easily move.

(6) The handle is a telescopic rod, so that the grid plates connected with the telescopic rod can reach higher height.

(7) According to the utility model, through the design of the clamping part on the sleeve, the replacement of the grid plate is facilitated, so that the detection requirements of air outlets with various dimensions are met.
