The measuring mechanism 2 comprises a slide seat 21, a measuring rod 22 and a pressure spring 23. The slide seat 21 is slidably connected in the upper sliding area 11. One end of the measuring rod 22 is connected to the slide seat 21, and the other end passes through the spacer block 3 downward and extends to the bottom of the lower measuring area 12. A pressure spring 23 is sleeved on the measuring rod 22 between the spacer block 3 and the slide seat 21. A receiving groove 221 is recessed at the lower end of the measuring rod 22, and a scale line 100 is arranged on the side wall of the lower end of the measuring rod 22. When in use, the receiving groove 221 at the lower end of the measuring rod 22 contacts the coating, and the receiving groove 221 is inserted into the coating under the downward sliding action of the slide seat 21, so that the coating thickness measurement result can be obtained by reading the value of the scale line 100. In order to facilitate the observation of the coating thickness, the measuring rod 22 is made of a transparent material.

[0029] In the utility model, the measuring rod 22 can be reset by the pressure spring 23 after the coating thickness detection is completed, thereby improving the flexibility of the equipment during use; the utility model adopts a method of arranging a receiving groove 221 in the test rod 22 to replace the test needle structure to test the coating thickness in a method of expanding the contact area with the coating, thereby avoiding end face wear during long-term or multiple uses, thereby ensuring the accuracy of the final test result and avoiding misjudgment that affects the result acceptance.
