This makes the installation process complicated and affects the assembly speed and efficiency of the high-pressure fuel pipe and the injector.

[0006] (2) When installing the existing high-pressure oil pipe, it is necessary to manually push the injector interface to move it so that it corresponds to the high-pressure oil pipe. This makes the assembly difficult to control and has poor accuracy, which affects the assembly efficiency. Summary of the invention

[0007] The purpose of the present invention is to overcome the defects in the prior art that when the high-pressure oil pipe is installed, it is necessary to control the angle of the injector interface in real time to make it correspond to the high-pressure oil pipe. In this way, the operation is cumbersome during the installation process, which affects the assembly speed and efficiency of the high-pressure oil pipe and the injector, and the injector interface needs to be manually pushed to move it to correspond to the high-pressure oil pipe, which makes the assembly difficult to control and the accuracy is poor, affecting the assembly efficiency.

When the adjustment part slides and adjusts the position along the length direction of the mounting groove body 4, the adjustment rod 3 moves horizontally, so as to achieve the effect of pushing the horizontal angle of the injector interface to change, thereby facilitating the installation of the high-pressure oil pipe.

[0028] By adopting the above technical solution:

[0029] When the device is in use, the support frame 11 is fixedly installed on both sides above the injector, so that the mounting plate 12 is horizontally erected above the injector interface. At this time, the adjusting rod 3 is located on one side of the injector interface. Before the injector interface is connected to the high-pressure oil pipe, the angle of the injector interface needs to be adjusted. When adjusting, the horizontal position of the adjusting rod 3 is adjusted by the adjusting component. When the adjusting rod 3 moves horizontally, the horizontal angle of the injector interface is pushed to change, which is convenient for the installation of the high-pressure oil pipe.

[0030] Example 2

[0031] On the basis of Example 1, in this embodiment, the adjustment part includes a stud 212, a locking nut 211 and a connecting kit 213, wherein the stud 212 is installed through the mounting groove 4, the locking nut 211 is screwed and sleeved on the top of the stud 212, the connecting kit 213 is fixedly installed on the top of the stud 212, the connecting kit 213 is in contact with the bottom of the mounting plate 12, and the top of the adjusting rod 3 is detachably installed on the connecting kit 213.

[0035] Example 3

[0036] On the basis of Example 1, in this embodiment, the adjustment part includes a slide 223 and an adjusting screw 224, wherein the slide 223 is slidably installed in the mounting groove 4, the top of the adjusting rod 3 is detachably installed under the slide 223, a lead screw nut is nested inside the slide 223, the adjusting screw 224 is rotatably installed in the mounting groove 4, and is arranged through the length direction of the mounting groove 4, the adjusting screw 224 is adapted to the lead screw nut, the adjusting screw 224 is screwed and sleeved in the lead screw nut, and one end of the adjusting screw 224 is sleeved with a damping adjustment wheel 222 for rotating the adjusting screw 224.

The limiting slider 225 is adapted to the limiting groove 221, and the limiting slider 225 is slidably installed in the limiting groove 221. Such a structural arrangement makes it possible for the slide 223 to be more temperature-resistant during horizontal movement under the mutual limiting action of the limiting slider 225 and the limiting groove 221.

[0038] There are two groups of limit sliders 225 , which are respectively installed on both sides of the slide 223 and are symmetrical to each other, so that the forces on both sides of the slide 223 are balanced, thereby ensuring the service life of the slide 223 .

[0039] By adopting the above technical solution:

[0040] When the damping adjustment wheel 222 is rotated, the adjusting screw 224 rotates. Since a lead screw nut adapted to and sleeved with the adjusting screw 224 is nested inside the slide 223, the slide 223 moves horizontally when the adjusting screw 224 rotates, thereby changing the horizontal angle of the injector interface, which is convenient and quick to operate.
