DETAILED DESCRIPTION
[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application.

[0019] The protection assembly 10 includes two elastic sleeves, two elastic sleeves are clamped on the top and bottom of the measuring plate 2, and the protection plate is fixedly connected between the side ends of the two elastic sleeves,
[0020] The fixed plate 3 is slidingly connected in the positioning frame 1, and the first compression spring 4 is fixedly connected between the side surface of the fixed plate 3 and the inner surface of the positioning frame 1,

[0022] When the thickness of the steel reinforcement cover is measured, the movement of the measuring plate 2 drives the sliding end of the electronic vernier caliper 5 to move, and the high-precision measurement principle of the electronic vernier caliper 5 can be used to realize accurate measurement of the thickness of the steel reinforcement cover,
[0023] The top surface and the bottom surface of the positioning opening of the positioning frame 1 are respectively fixedly connected with the limiting plates 8, the two limiting plates 8 can be clamped on the steel reinforcement frame, and the limiting effect of the positioning frame 1 is realized,
[0024] Two limiting plates 8 are respectively fixedly installed with inclined lighting lamps 9, and the irradiation directions of the two lighting lamps 9 are towards the protection assembly 10, and the inclination angles of the two lighting lamps 9 are different, so that the two lighting lamps 9 can provide sufficient local illumination in the detection environment with poor lighting conditions such as dim light or night.
