[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a fixing device for a horizontal vertical combustion tester of the utility model comprises a U-shaped plate 1, a plurality of clamping seats and a plurality of test samples 7, wherein a channel for the clamping seats to move is formed inside the U-shaped plate 1, the clamping seats are arranged in the channel, one end of the test samples 7 are clamped and fixed on the clamping seats, a plurality of fixing plates 8 are installed in groups of two on one side surface of the U-shaped plate 1, an active roller 12 and a driven roller 13 are movably installed between the fixing plates 8, a conveyor belt 9 is wound around the outside of the active roller 12 and the driven roller 13, a plurality of slots 10 are arranged on the outer ring surface of the conveyor belt 9, and an inserting portion 17 is protruded on one side surface of the clamping seat, and the inserting portion 17 is inserted into the corresponding slot 10;

[0023] Among them, a reduction motor for driving the active roller to rotate is installed on the fixed plate on which the active roller is installed, and the rotation of the active roller and the conveyor belt can be driven by the reduction motor.

[0024] In this embodiment, the clamping seat is composed of a left clamping block 5 and a right clamping block 6. The top and bottom surfaces of the left clamping block 5 and the right clamping block 6 are protruded to form a positioning portion 16. Adjacent positioning portions 16 are combined to form a positioning block. The top and bottom surfaces of the channel are provided with positioning grooves 2 that match the positioning blocks. The positioning blocks are slidably set in the positioning grooves 2. The bottom surface of the lower positioning groove 2 is laterally provided with a strip opening 3 that communicates with the outside world. The bottom surfaces of the left clamping block 5 and the right clamping block 6 are provided with clamping grooves 15. The lower ends of the clamping grooves 15 pass through the lower positioning portion 16. The upper ends of the test samples 7 pass through the strip opening 3 and are clamped in the corresponding clamping grooves 15.

[0025] In this embodiment, a plurality of positioning grooves 2 are provided on the inner side surface of the left clamping block 5, and a plurality of positioning columns 14 are protruded on the inner side surface of the right clamping block 6. The positioning columns 14 are inserted into the positioning grooves 2.
