[0024] Furthermore, a placement groove 13 is provided inside the limiting strip 5, and the placement groove 13 is arranged in a "U" shape in the middle of the limiting strip 5, which facilitates the placement of the light plate inside the limiting strip 5 through the placement groove 13. In order to achieve the stability of the light plate inside the limiting strip 5, a limiting unit is provided inside the limiting strip 5. The limiting unit includes a return spring 14, which is fixedly connected inside the limiting strip 5. At the same time, a sliding plate 15 is fixedly connected to the other end of the return spring 14, and the sliding plate 15 is slidably connected inside the limiting strip 5, which facilitates the movement of the sliding plate 15 inside the limiting strip 5.

The slide rail 17 is located on both sides of the placement groove 13 to ensure the movement path of the slide plate 15. In order to clamp the light plate, clamping blocks 16 are fixedly installed on the surface of the slide plate 15. There are two clamping blocks 16 symmetrically arranged about the central axis of the placement groove 13.

[0025] To achieve the pressure distribution effect inside the chamber 1 during heat treatment, two through holes 6 are drilled through the interiors of both the gas storage box 4 and the chamber 1. This improves the pressure distribution efficiency inside the chamber 1. The two through holes 6 are positioned correspondingly between the gas storage box 4 and the chamber 1 to ensure air pressure flow.
