[0002] During the repair of main and auxiliary engines of ships, cylinder head injectors often need to be replaced, cleaned, and maintained. Without suitable disassembly tools, it is often difficult to remove the injectors smoothly. The process of removing the injectors is time-consuming and there is a risk of damaging the injectors and the cylinder head body during the removal process. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a damage-proof injector quick disassembly tool to solve the current pain points in this field.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A damage-proof fuel injector quick disassembly tool comprises an L-shaped plate, wherein a first through hole and a second through hole are provided on the horizontal plate of the L-shaped plate, a positioning stud is inserted into the first through hole, the upper end of the positioning stud is fixed by a nut, a lifting screw is inserted into the second through hole, a nut is screwed on the upper end of the lifting screw, which can limit the movement of the lifting screw, a threaded sleeve is threadedly installed at the lower end of the second through hole, a sleeve is rotatably installed at the lower end of the threaded sleeve, the sleeve can be put on the fuel injection port, a locking bolt is installed on the side of the sleeve, and the locking bolt can fix the sleeve after it is put on the fuel injection port.

[0006] It is further explained that a reinforcement block is welded on the lower side of the L-shaped plate transverse plate to increase the strength of the L-shaped plate transverse plate.

[0007] To sum up, the beneficial effects of the present invention compared with the prior art are as follows: the device is a combined tooling assembly installed above the cylinder head, which is used in conjunction with the screw assembly and the L-shaped adjustable bracket. During the removal of the injector, it can ensure that there is no risk of damage to the injector and the cylinder head, and the removal is quick, effective, time-saving and labor-saving.
