A limit rod 8 is provided on the top surface of the working plate 1, and the limit rod 8 passes through the through holes on the top surface of the mounting plate 3 and is slidably connected with the limit holes on the same side of the top surface of the working plate 1, which can limit the mounting plate 3 and thus limit the rust degree detector 4 to prevent the rust degree detector 4 from shifting in position during the detection process.

[0041] It is worth noting that a support plate 10 is fixed to the bottom end of the support column 2, and an anti-skid plate 11 that matches its shape is fixed to the bottom end of the support plate 10, and the thickness of the anti-skid plate 11 is 1-5 cm, and 3 cm is preferably used in this article, so as to increase the contact area and friction between the entire device and the ground, thereby making the entire device more stable during operation.

This can make the connection between the guide block 54 and the limit bar 9 and the guide groove on the top surface of the working plate 1 tighter, and indirectly make the two manual rotary chucks 53 and the rust degree detector 4 more stable during movement.

[0043] Finally, it should be noted that the detector body 41, electromagnetic induction probe 42, electrochemical probe 43, manual rotating chuck 53, motor 55 and other components involved in the present invention are all universal standard parts or components known to those skilled in the art.

[0044] The present embodiment is used in a specific process, when it is necessary to inspect the steel bar 7, first the turntable 66 is rotated by the dial post 67, and the rotation of the turntable 66 drives the connecting post 65 fixed thereto coaxially to rotate, and the rotation of the connecting post 65 drives the rotating post 62 on the same side fixed thereto coaxially to rotate, and the rotation of the rotating post 62 drives the two-way screw rod 63 fixed thereto coaxially to rotate, and the rotation of the two-way screw rod 63 drives the two connecting rods 64 threadedly connected thereto to move, and the two connecting rods 64 move to drive the two movable plates 51 to move, and the movable plate 51 moves under the guidance of the guide block 54 on the same side and the guide groove on the top surface of the working plate 1, and the movement of the two movable plates 51 drives the two manual rotating chucks 53 to move, and when the distance between the two manual rotating chucks 53 is appropriate, the rotation of the dial post 67 is stopped, and then the steel bar 7 can be clamped and fixed by the two manual rotating chucks 53;

[0045] When it is necessary to inspect the steel bar 7, the mounting plate 3 is first moved. The mounting plate 3 moves under the guidance of the limit bar 9 and the guide groove on the top surface of the working plate 1. The movement of the mounting plate 3 drives the rust degree detector 4 fixed thereto to move. When the rust degree detector 4 moves to the appropriate position, the limit rod 8 is inserted into the through hole on the top surface of the mounting plate 3 and slidably plugged into the limit hole on the same side on the top surface of the working plate 1. Then, the rust degree of the steel bar 7 can be detected by the electromagnetic induction probe 42 and the electrochemical probe 43. The motor 55 is started by the external PLC. The output shaft of the motor 55 rotates to drive the roller 52 on the same side coaxially connected to it to rotate. The rotation of the roller 52 drives the manual rotating chuck 53 on the same side fixed thereto to rotate.
