[0029] More specifically, when placing the engine, the pointing block 10 is used as a reference so that when the engine is fixed, its nozzle is aligned with the pointing block 10. When the injection angle is tested, the gas ejected from the nozzle will be ejected toward the test plate. Under the support of the test column 8, the test plate 9 is deflected by the airflow.

[0031] Specifically, the control button 13 is used to control the fixed platform 2 to rotate under the transmission of the transmission member 14, so that the fixed platform 2 drives the engine to rotate and adjust the injection direction of the nozzle. There is no need to disassemble the engine, which is convenient for testing the injection state of the engine nozzle in different directions.
[0032] Please refer to Figure 3 As a further implementation of the transmission member: the transmission member 14 includes a transmission gear 141 and a transmission gear ring 142, the radius of the transmission gear 141 is smaller than the transmission gear ring 142, the transmission gear 141 cooperates with the control button 13, and a rotating column 15 is provided at the lower end of the fixed platform 2.

[0036] Please refer to Figure 1-Figure 4 As a further implementation of the sliding clamp: guide grooves 19 are opened at both ends of the test bench 1, and guide rods 20 are arranged in the guide grooves 19. A guide block 21 is provided at the lower end of the sliding clamp 7, and the guide block 21 is slidably matched with the guide grooves 19 and the guide rods 20.
[0037] Specifically, when the sliding clamp plate 7 moves, the guide block 21 is driven to move. The guide block 21 slides in the guide groove 19 and is restricted by the guide rod 20, so that the movement of the sliding clamp plate 7 remains stable.
[0038] Please refer to Figure 3 As a further implementation of the driving screw: a first driving handle 22 and a second driving handle 23 are provided at the outer end of the test bench 1, the first driving handle 22 cooperates with the first driving screw 4, the second driving handle 23 cooperates with the second driving screw 5, and the first driving handle 22 and the second driving handle 23 are both provided with anti-slip patterns 24.
[0039] Specifically, the first driving handle 22 is used to control the rotation of the first driving screw rod 4, and the second control handle is used to control the rotation of the second driving screw rod 5. The sliding clamps 7 at both ends of the operation move independently, and the anti-slip grooves 24 make the rotation operation more stable.
[0040] Please refer to Figure 5 As a further implementation of the test plate: a rotating ring 25 is provided on the test plate 9 , a bearing 26 is provided inside the rotating ring 25 , and the rotating ring 25 is rotatably matched with the test column 8 through the bearing 26 .

[0043] Specifically, when the fixed platform 2 is rotated, the first scale ring 27 is used to determine the rotation amplitude of the fixed platform 2 and the orientation state of the engine nozzle, and the second scale ring 28 provides an indication to facilitate determination of the state of the test plate 9 when it is deflected.
[0044] In summary, when the device is used:
[0045] The engine is mounted on the fixed platform 2, and the engine is supported by the fixed platform 2, and the first driving screw rod 4 and the second driving screw rod 5 are controlled to rotate, and the first driving handle 22 is used to control the first driving screw rod 4 to rotate, and the second driving screw rod 5 is controlled to rotate by the second control handle, so that the sliding clamps 7 at both ends move independently, and the anti-slip pattern 24 makes the rotation operation more stable, so that the first driving screw rod 4 and the second driving screw rod 5 cooperate with their respective corresponding sliding blocks 6, and the corresponding sliding clamps 7 are driven to move by the sliding blocks 6. When the sliding clamps 7 move, the guide blocks 21 are driven to move, and the guide blocks 21 slide in the guide grooves 19 and are restricted by the guide rods 20, so that the movement of the sliding clamps 7 remains stable, so as to control the movement of the sliding clamps 7 at both ends, clamp the engine in the middle, and the two sets of driving screw rods work independently, and the positions of the two sliding clamps 7 can be freely adjusted, and engines with different structures can be fixed, so that the nozzle structure of the engine is facing the middle of the test bench 1, and the stability of the test is ensured. If it is necessary to test the injection effect of the engine nozzle in different directions, the control button 13 can be turned to control it. When the control button 13 is turned, the worm 17 will be driven to rotate, and the worm 17 will cooperate with the worm wheel 18 to drive the rotating shaft 16 to rotate, and then the rotating shaft 16 drives the transmission gear 141 to rotate, so that the rotation of the transmission gear 141 is controlled by the control button 13, and the transmission gear 141 and the transmission gear ring are matched to form a transmission member 14, so that the transmission gear ring is rotated, and the transmission gear ring is driven by the rotating column 142 to drive the gear ring; 15 is rotated, thereby driving the fixed platform 2 to rotate, and the radius of the transmission gear 141 is much smaller than the transmission gear ring. During transmission, the transmission gear 141 rotates one circle, and the transmission gear ring only rotates partially, so that the rotation amplitude of the fixed platform 2 is more accurately adjusted. By rotating the fixed platform 2, the fixed platform 2 drives the engine to rotate, and the injection direction of the nozzle is adjusted. There is no need to disassemble the engine, which is convenient for testing the injection state of the engine nozzle in different directions.
[0046] When placing the engine, the pointing block 10 is used as a reference so that when the engine is fixed, its nozzle is aligned with the pointing block 10. When the injection angle test is performed, the gas ejected from the nozzle will be ejected toward the test board. Under the support of the test column 8, the test board 9 is affected by the airflow. The test board 9 is rotatably connected to the test column 8 through the rotating ring 25. Under the rotation provided by the bearing 26, the smooth rotation is maintained. Under the influence of the airflow, it is deflected toward the direction of gas flow. The identification strip 12 is set on the observation cover 11. The observation cover 11 is made of transparent material. The identification strip 12 is compared with the test board 9 to observe whether the deflection of the test strip meets expectations, thereby judging the injection angle of the nozzle. When the rotation of the test board 9 does not meet expectations, the second scale ring 28 provides an indication to facilitate judging the state of the test board 9 when it is deflected. When the fixed platform 2 is rotated, the first scale ring 27 is used to judge the rotation amplitude of the fixed platform 2 and the orientation state of the engine nozzle. The deflection state of the test board 9 can also be timely judged through the second scale ring 28.
