The plug-in fixes the connection position between the water temperature sensor 4 and the assembly cavity 3; in the present embodiment, by providing the boss 7 and the groove 11, the water temperature sensor 4 can pass through one end of the fixing frame 6 through the extension groove 5 and be buckled in the assembly shell 2, so that the water temperature sensor 4 and the assembly cavity 3 form a strong buckle structure through the boss 7, which effectively prevents the water temperature sensor 4 from falling off from the assembly shell 2, effectively enhances the structural strength, and reduces the connection difficulty; by providing the plug-in column 8 and the plug-in groove 10, the connection position of the water temperature sensor 4 in the assembly cavity 3 can be quickly located, and the connection position between the fixing frame 6 and the extension groove 5 can be locked, so as to prevent the water temperature sensor 4 from shifting in the assembly shell 2 and avoid affecting the use effect of the present embodiment.
