[0033] Among them, the vibration motor 11 and the buzzer 9 provide tactile and sound prompts respectively, which are convenient for identifying the completion of measurement and the measurement frequency in a noisy environment. The circuit board 8 is arranged inside the main shell 4, and the main shell 4 is connected to the probe 12, and is fixed by the top shell 5 to form a waterproof structure. Waterproof glue is provided in the assembly of the top shell 5 and the main shell 4 and in the annular space (X)(Y) around the circuit board 8 to ensure the waterproof performance of the thickness gauge. The power module 14 not only provides a stable power supply for the thickness gauge, but also has protection functions such as overcharging, over-discharging, and overcurrent, which improves energy efficiency and convenience of use. The TYPE-C interface 7 supports charging and data transmission, has a waterproof function, and adopts waterproof measures such as waterproof plugs or waterproof rubber rings to prevent water intrusion from causing damage to the device.

When it is close to the object to be measured, the micro switch 13 is triggered by compressing the spring 3, thereby activating the measurement function of the circuit board 8. The design of the probe cover 1 not only extends the service life of the probe 12, but also improves the accuracy and stability of the measurement.
