[0024] A mounting plate 5 is fixedly mounted on the surface of the mounting plate 4, a first threaded rod 6 is vertically rotatably mounted on the upper surface of the mounting plate 5, a clamping plate 7 is threadedly sleeved on the first threaded rod 6, and the clamping plate 7 is restricted in rotation by a restriction component, the restriction component includes a restriction rod 8 vertically fixedly mounted on the upper surface of the mounting plate 5, the clamping plate 7 is slidably sleeved on the restriction rod 8, and the two mounting plates 4 are controlled to rotate together through a transmission assembly;

[0025] When it is necessary to inspect the metal material, first place one end of the metal material on the upper surface of one of the mounting plates 5, and then rotate the first threaded rod 6, and then the clamping plate 7 threadedly sleeved on the first threaded rod 6 will move vertically under the restriction of the restriction rod 8 until the metal material is clamped and fixed between the mounting plate 5 and the clamping plate 7. The metal materials of different thicknesses can be clamped, which improves the practicability of the device.

[0026] After the metal material is fixed, the third threaded rod 15 is controlled to rotate by starting the driving motor 18, so that the slide 16 threadedly sleeved on the third threaded rod 15 moves laterally with the detection head 17, and the surface of the metal material can be detected;

[0027] The design of the two clamping plates 7 and the two mounting plates 5 enables the detection mechanism to detect two metal materials at the same time, without the need to detect the metal materials one by one, thereby improving the work efficiency of the external detection of the metal materials.

[0028] The transmission assembly includes two toothed rings 9 respectively fixedly sleeved on the outer disk walls of the two mounting plates 4, two rack rods 10 respectively meshingly connected with the two toothed rings 9 and a first driving component.

[0032] In the utility model, when it is necessary to detect the metal material, first place one end of the metal material on the upper surface of one of the mounting plates 5, and then rotate the first threaded rod 6. At this time, the clamping plate 7 threadedly sleeved on the first threaded rod 6 will move vertically under the limiting action of the limiting rod 8 until the metal material is clamped and fixed between the mounting plate 5 and the clamping plate 7. Metal materials of different thicknesses can be clamped, which improves the practicality of the device. The design of the two clamping plates 7 and the two mounting plates 5 allows the detection mechanism to detect two metal materials at the same time, without the need to detect the metal materials one by one, thereby improving the work efficiency of external detection of metal materials.
