[0002] The injector's function is to spray the propellant into the combustion chamber, atomizing and mixing it. One of the most important components in a gas generator is the injector, which acts like a fuel injector in a gasoline or diesel engine, atomizing the fuel and oxidizer and spraying them into the combustion chamber to facilitate combustion.

[0003] For example, the application publication number "CN102072046A" discloses a test gas-gas combustion chamber bracket device. By moving the rolling ball shaft of the bracket device, the engine body can be disassembled, thereby facilitating the replacement of the multi-nozzle gas-gas injector assembly in the engine head. This solves the difficulty of moving heavy engines and makes the replacement of multi-nozzle gas-gas injectors very convenient. However, the device is inconvenient when installing the injector. The device uses bolts and other structures to quickly install the injector, but when the operator installs the injector with the bolts, the operator needs to perform a lot of manual operations, which increases the operator's workload when using the device. At the same time, the device only installs and fixes the injector in one way, making it unable to adapt to high-intensity work and resulting in poor fixation of the injector. Utility Model Content

A plurality of sets of threaded holes are provided on the surface of the mounting plate 1, and the surface of the arc plate 205 is fixedly connected to the top plate 8. The top plate 8 and the surface of the arc plate 205 are both slidably connected to the slideway provided on the surface of the bent plate 4, fixing the moving track of the top plate 8. The surface of the top plate 8 is frosted, so that the friction between the top plate 8 and the surface of the injector can be increased. The mounting plate 1 is threadedly connected to multiple bolts 7 through the threaded holes provided on the surface. The mounting plate 1 can be fixed by four bolts 7, and one end of multiple bolts 7 passes through the surface of the mounting plate 1.

[0023] Refer to the attached Figure 1-6 : The locking device 9 includes a fixed block 901 and a frame 902. The fixed block 901 is fixedly connected to the surface of the bent plate 4 on one side, and the frame 902 is fixedly connected to the surface of the bent plate 4 on the other side. The surface of the fixed block 901 is tightly pressed against the surface of the frame 902. The frame 902 is slidably connected to the surface of the threaded rod 903 through a slideway opened on the surface, so that the threaded rod 903 can slide in the slideway on the surface of the frame 902. One end of the threaded rod 903 passes through the surface of the frame 902 and is fixedly connected to the hexagonal block 904.

[0024] The threaded rod 903 can be easily rotated through the hexagonal block 904. A circular plate 906 is fixedly connected to the surface of the threaded rod 903.

[0026] Working principle:

[0027] When installing the injector:

[0028] Bracket installation process:

[0029] The mounting plate 1 is fixed to a suitable position by four sets of bolts 7, and the injector is placed in the middle of the bent plates 4 on both sides. The bent plates 4 on both sides are turned to rotate around the hinge of the connecting rod 5 and the base 6 so that one end of the bent plates 4 on both sides can be tightened, so that the fixed block 901 and the surface of the frame 902 can be tightened. Under the push of the spring 905, the circular plate 906 can be pushed to move, so that the circular plate 906 can drive the threaded rod 903 to move synchronously, so that one end of the threaded rod 903 can be tightened with the threaded hole on the surface of the fixed block 901. The operator rotates the hexagonal block 904 so that the hexagonal block 904 can drive the threaded rod 903 to rotate, so that the threaded rod 903 can be threadedly connected to the threaded hole on the surface of the fixed block 901, so that the position of the bent plates 4 on both sides is fixed, so that the bent plates 4 on both sides can quickly clamp and fix the injector.

[0030] Further locking process:

[0031] The operator pulls out the latch 10 on the surface of the slide box 3, and at the same time, the operator holds the handles 202 on both sides, so that the handles 202 on both sides can drive the rotating rods 201 on both sides to rotate a certain angle with the fixed column 203 as the center, so that the rotating rods 201 on both sides push the sliding rod 204 to move at the same time through the lever principle, so that the sliding rod 204 can drive the top plate 8 to be further tightened to the surface of the injector through the arc plate 205, and by adjusting the position of the sliding rods 204 on both sides, the grooves on the surface of the sliding rod 204 can be engaged with the latch 10 again, so that the injector can be further fixed.
