The top of the threaded block 63 is connected to the moving assembly 10. The output end of the motor 61 drives the threaded rod 62 to rotate, so that the threaded block 63 drives the workbench 5 to move closer to the flame-spraying device 3 through the moving assembly 10.

[0025] The moving component 10 includes a limiting strip 101, which is inserted into the upper end of the threaded block 63 and passes through the top of the threaded block 63. The top of the limiting strip 101 is fixedly connected to the bottom of the workbench 5. A limiting plate 102 is fixedly installed on the front side wall of the limiting strip 101. By holding the front end of the limiting strip 101, the workbench 5 can be pulled out of the cabinet 1, making it convenient to place the material to be tested onto the clamping component 8. The limiting plate 102 can be used to position the workbench 5 back into the cabinet 1.
