[0016] 1. Comprehensive limiting and preventing displacement: four rotating plates are arranged at the openings of the U-shaped grooves, and cooperate with the resisting mechanism to comprehensively clamp the oil injection nozzle. When the oil injection nozzle is installed, the rotating plates are passively rotated to drive the resisting mechanism to work, and then the fixed bolts in the threaded holes act on the resisting mechanism to reinforce the clamping force on the oil injection nozzle, thereby preventing the oil injection nozzle from being radially displaced when the engine is running and vibrating.

[0039] In use, the oil nozzle is fixedly installed, after the pressing plate 1 is taken out, the pressing plate 1 is installed at the position between the two groups of oil nozzles, and the U-shaped groove 3 opened inward at both ends of the pressing plate 1 is inserted into the oil nozzle, in the process, the oil nozzle is inserted into the U-shaped groove 3, and the both sides of the oil nozzle are in contact with the outside of the rotating plate 6 and the clamping plate 4, the outside of the rotating plate 6 and the clamping plate 4 is contacted by the oil nozzle and drives the rotating plate 6 to rotate in the rotating groove 5 under the action of the torsional spring bearing 15, and the rotating plate 6 is folded into the rotating groove 5, at this time, the oil nozzle is completely inserted into the U-shaped groove 3 and presses the abutting plate 10, the abutting plate 10 is pressed inward to abut the rod 11, at this time, the abutting plate 10 is pressed inward after being pressed to completely insert the oil nozzle into the U-shaped groove 3, and the both sides of the oil nozzle are separated from the rotating plate 6 and the clamping plate 4, at this time, the rotating plate 6 continues to maintain the vertical state, and the both sides of the oil nozzle are clamped by the rotating plate 6 and the clamping plate 4, and the fixing bolt is threadedly inserted into the threaded hole 12 to fix and install the pressing plate 1;

[0040] After the bolt is threadedly inserted into the threaded hole 12, the surface of the bolt presses the abutting ball 19 and the top ball 20 movably inserted into the threaded hole 12:

[0041] After the bolt presses the abutting ball 19, the abutting ball 19 drives the abutting rod 11 to insert the abutting plate 10 into the U-shaped groove 3, so that the abutting plate 10 presses and abuts the surface of the oil nozzle inserted into the U-shaped groove 3, and the rotating plate 6 and the clamping plate 4 arranged at both ends of the opening of the U-shaped groove 3 clamp and fix the oil nozzle, to prevent displacement of the oil nozzle during long-time operation and vibration of the engine;
