[0002] The non-stick coating on the inner pot of the rice cooker can prevent rice from sticking to the pot. The coating thickness is an important indicator to characterize the quality of the inner pot of the rice cooker and is one of the main process parameters that need to be controlled during the manufacturing process of the inner pot of the rice cooker. The coating thickness measuring instrument can non-destructively measure the thickness of the non-magnetic coating on the magnetic metal substrate and the thickness of the non-conductive coating on the non-magnetic metal substrate. The coating thickness measuring instrument in the prior art is mainly composed of a body and a probe. The probe is connected to the body through a wire electrical signal, and a display screen and function buttons are provided on the body.

[0003] For example, a coating thickness measuring instrument with Chinese patent number CN208936955U is disclosed. In the utility model, a winding hook and an elastic splint are provided to store and fix the wire and the probe. A rubber sleeve and a spherical rubber are provided to reduce the possibility of the wire coming off the first hook body and the second hook body, thereby increasing the safety of the winding hook. However, in the utility model, the storage and fixing structure is provided on the back of the measuring instrument, which may interfere with the placement of the measuring instrument.
