A clamp seat 3 for fixing the combustion tube 4 is fixedly mounted on the power end of the electric push rod 2, and the combustion tube 4 is installed on the power end of the electric push rod 2 through the clamp seat 3.

[0025] In a specific implementation, the position of the combustion tube 4 in the test box 1 can be adjusted and changed by controlling the electric push rod 2 .

[0026] It should be noted that an igniter 5 is fixedly mounted on the inner bottom wall of the test box 1 , and the igniter 5 is connected to the combustion tube 4 through a wire. The igniter 5 is specifically an electronic igniter, which generates sparks through electronic components to ignite the fuel in the combustion tube 4 .

[0027] In this embodiment, the clamp component includes a connecting seat 6 , a first clamp frame 8 fixedly mounted on the connecting seat 6 , and a second clamp frame 9 hinged to the first clamp frame 8 .

[0028] In a specific implementation, five samples of 300 mm*89 mm are cut from the flame retardant material to form a group, which are clamped by the first clamping frame 8 and the second clamping frame 9 and placed in the test box 1 for a combustion test.

[0029] Preferably, a protrusion 10 is fixedly mounted on the first clamping frame 8, and a groove 11 for the protrusion 10 to fit into is opened on the second clamping frame 9. By snapping the protrusion 10 into the groove 11, the matching position accuracy of the first clamping frame 8 and the second clamping frame 9 can be improved.

[0030] In this embodiment, an elastic member for fixing the first clamping frame 8 and the second clamping frame 9 is also provided on the outer side of the second clamping frame 9. The elastic member includes a U-shaped fastener 13, a spring 16 fixedly installed on the inner wall of the fastener 13, and a pressure plate 17 fixedly connected to the spring 16.

The size of the limit block 15 is larger than the size of the sliding rod 12. By sliding the limit block 15 relative to the sliding hole 14, the limit block 15 can be limited from being separated from the fastener 13.

[0033] The outer side of the connecting seat 6 in this embodiment is also fixedly connected with a plug rod 7 with a star-shaped cross section. The inner wall of the test box 1 is provided with a plug hole for the plug rod 7 to be inserted.
