[0020] Please see Figure 4 The flame-spraying assembly 3 includes two support plates 301 installed on the left side of the chassis 1. A threaded rod 303 is rotatably mounted on one side of the two support plates 301 that is close to each other via two bearings.

[0025] The implementation principle of the combustion device for testing the performance of wires and cables in this application embodiment is as follows: During use, the wire is placed between the L-shaped plate 404 and the baffle 401. The tension of the tension spring 405 causes the L-shaped plate 404 to move, thus clamping the wire. Then, filter paper is placed inside the groove 205, and the servo motor 202 is started. The servo motor 202 drives the support plate 206 to rotate through the rotating rod 203, so that the support plate 206 can carry the filter paper into the device and position the filter paper below the wire. Then, fuel is connected to the feed pipe 307 to supply fuel to the nozzle 308, causing the nozzle 308 to spray flames and burn the wire, thus completing the wire combustion test. During the combustion test, the dripping material falls onto the filter paper, and the exhaust gas generated during the combustion process is discharged through the exhaust pipe 101. After the wire test is completed, the servo motor 202 is started again to rotate the support plate 206 to the outside of the casing 1, so that the operator can remove the dripping material.
