[0021] like Figure 1 and Figure 2 As shown, a plurality of sliding rails 13 are provided at the inner bottom of the clamp housing 1, and a plurality of T-shaped sliders 14 are fixedly connected to the lower end of the ejection block 12. The outer side walls of the plurality of T-shaped sliders 14 are respectively slidably connected to the inner walls of the plurality of sliding rails 13. The structural design of the sliding rails 13 and the T-shaped sliders 14 can limit the ejection block 12 and prevent the ejection block 12 from rotating with the threaded rod 4.

[0022] like Figure 1 and Figure 2 As shown, a sliding rod 10 is fixedly connected to the middle part of the upper end of the special-shaped block 11, and the outer wall of the sliding rod 10 is slidably connected to the limiting frame 9. One side of the limiting frame 9 is fixedly connected to the inner wall of the clamp housing 1. The structural design of the disassembly pull rod 19 and the limiting frame 9 is used to limit the rising trajectory of the special-shaped block 11.

[0023] like Figure 1 and Figure 3 and Figure 4As shown, a mounting base 5 is fixedly connected to the middle part of the lower end of the fixture housing 1, and four fixing boxes 6 are fixedly connected to the outer wall of the mounting base 5.

When the equipment is turned on, its tensile performance is tested. When testing different refractory materials, different types of clamps need to be replaced, and the disassembly pull rod 19 is pulled upward. The protrusion of the disassembly pull rod 19 pushes the special-shaped block 17 inward. When the protrusion of the disassembly pull rod 19 is completely against one end of the special-shaped block 17, one side of the special-shaped block 17 releases the restriction of the connecting rod 7, so that the mounting base 5 can be removed from the testing equipment.
