The above-mentioned solution solves the problem that the existing fuel injector pressure plate has a fixed size of the clamping portion and cannot fix fuel injectors of different sizes, thus resulting in a low versatility.

[0028] According to this specific embodiment, the middle part 102 is arranged on one side of the supporting part 101; the threaded mounting hole 103 is arranged on one side of the middle part 102; the supporting part 101 is used to support the installation of the middle part 102, and the clamping assembly is fixed to a suitable position through the threaded mounting hole 103 on the middle part 102, and the injector is fixed through the clamping assembly.

[0029] The adjusting frame 105 is fixedly connected to the middle part 102 and is located on one side of the middle part 102; the adjusting member 106 is arranged on one side of the adjusting frame 105; the two clamping structures 107 are respectively located on one side of the adjusting member 106; the supporting frame 108 is fixedly connected to the adjusting member 106 and is located on one side of the adjusting member 106; the operating member 109 is arranged on one side of the supporting frame 108; the connecting plate 110 is fixedly connected to the operating member 109 and is located on one side of the operating member 109; the clamping portion 112 is arranged on one side of the connecting plate 110, and when the injector is adjusted When fixing, according to the size of the fixed part of the injector, the adjusting member 106 in the adjusting frame 105 is operated to move the clamping structures 107 on both sides close to the fixed part of the injector to a suitable position, and then the operating member 109 on the support frame 108 is operated to cooperate with the limiting of the guide member 111 to drive the connecting plate 110 to move, so that the clamping part 112 contacts the fixed part of the injector. By adjusting the opening and closing of the clamping part 112, the problem of the existing injector pressure plate having a fixed size of the clamping part and being unable to fix injectors of different sizes is solved, thereby resulting in a low versatility.
