[0006] As a preference, the clamping block is located inside the first groove, and the latch is located inside the movable groove.

[0007] As another preference, handles are fixedly connected to the outer surface of the swivel, and the number of the handles is two.

[0008] Further preferably, a baffle is fixedly connected to the outer surface of the waterproof shell, there are multiple baffles, and clamping blocks are arranged between adjacent baffles.

[0009] Preferably, a friction pad is fixedly connected to the lower surface of the clamping block, and the lower surface of the friction pad fits with the outer surface of the exhaust pipe.

[0010] As another preference, a heat-resistant ring is fixedly connected to the inner surface of the waterproof shell, and a heat-insulating tube is fixedly connected to the rear side of the heat-resistant ring.

[0011] Further preferably, a heat absorbing tube is fixedly connected to the inner surface of the heat insulation tube, and a heat dissipation ring is fixedly connected to the front side of the heat absorbing tube.

[0013] Compared with the existing waterproof exhaust pipe heat insulation cover, through the handle, swivel, waterproof shell, pin, movable groove, clamping block, exhaust pipe and protective cover, the handle is turned during use to drive the swivel to rotate, and then drive the swivel to move along the waterproof shell, and then drive the pin to move along the waterproof shell, and then drive the pin to move along the movable groove, and then drive the clamping block to move toward the direction close to the exhaust pipe, so that the clamping block fixes the protective cover on the outer surface of the exhaust pipe. Compared with the existing heat insulation cover, the heat insulation cover may be damaged due to high temperature during long-term use. The usual heat insulation cover is generally fixedly installed on the outside of the exhaust pipe. It is very difficult to remove the heat insulation cover, and replacement is time-consuming. When the waterproof exhaust pipe heat insulation cover needs to be replaced, the heat insulation cover can be quickly removed, which is more convenient for disassembly and assembly of the heat insulation cover, and the replacement operation saves more time.
