The manifold can be stuck in the anti-slip groove 22 and the bottom groove 23 to limit the deviation of the injector. The side plate 11 forms a folded plate with an L-shaped cross section. The top of the main body 10 The surface and side walls are provided with threaded holes, and the wall surface of the side panel 11 is provided with mounting holes, and the bolts are fastened through the mounting holes and the threaded holes. The protrusion 12 forms a rectangular block structure, and the limiting groove 13 extends from the top to the bottom of the protrusion 12. The depth of the limiting groove 13 is less than the height of the protrusion 12. The heights of the two sides of the protrusion 12 are different. A notch is formed between the lower side of the protrusion 12 and the second splint 21 for the trachea to enter the limiting groove 13. The first splint 20 forms an arc-shaped plate structure, and one end of the first splint 20 is in contact with the inner wall of the protrusion 12. The first splint 20 is fixedly connected, and the other end of the first splint 20 forms a free end. The first splint 20 can be bent and extended. The anti-slip groove 22 is opened on the convex surface of the first splint 20. The convex surface of the first splint 20 forms a curved surface extending downward through the anti-slip groove 22. The second splint 21 forms an arc-shaped plate with a D-shaped cross section. The second splint 21 is bent upward to form a bottom groove 23. The bottom groove 23 forms an arc-shaped notch. The bottom groove 23 is located obliquely above the anti-slip groove 22. In this solution, by moving the manifold from the bottom groove 23 and the convex 12-shaped The notch formed is pushed into the limiting groove 13, and the manifold is clamped and limited by the bottom groove 23 and the anti-slip groove 22 through the limitation of the second clamping plate 21 and the first clamping plate 20, which can realize the elastic clamping of the manifold. On the basis of ensuring the rotation of the manifold in the circumferential direction, it can suppress the manifold from jumping due to the operation of the engine, has a better limiting effect on the manifold, is convenient to install, and is easy to assemble. The first clamping plate 20 and the second clamping plate 21 can be made of elastic steel, such as spring steel, and the specific type is not restricted too much here.

The top of the main body 10 is provided with a number of round holes for installing bolts, which are fastened to the engine. By limiting the manifold of the injector with the protrusion 12, the circumferential rotation of the injector can be suppressed. The connecting block 24 can be lifted, and the connecting block 24 drives the mounting plate 25 to bend. The mounting plate 25 is also made of spring steel. Then the connecting block 24 drives the second clamping plate 21 away from the first clamping plate 20, so that the distance between the second clamping plate 21 and the first clamping plate 20 is increased, thereby facilitating the manifold to enter between the first clamping plate 20 and the second clamping plate 21, and pushing the manifold into the limiting groove 13 from the notch formed by the bottom groove 23 and the protrusion 12. Through the limitation of the second clamping plate 21 and the first clamping plate 20, the manifold is clamped and limited by the bottom groove 23 and the anti-slip groove 22, which can realize the elastic clamping of the manifold. On the basis of ensuring the rotation of the manifold in the circumferential direction, it can suppress the manifold from jumping due to the operation of the engine.
