[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] Combined with Figure 1 A bushing puller for disassembling an aircraft engine regulator comprises a pull rod 1, a turning handle 2 is provided at the top of the pull rod 1, an impact hammer 3 is sleeved on the pull rod 1, and a mounting ring 16 is provided on the pull rod 1 and above the thread 4.

[0025] Through the above structure, the impact hammer 3 can be directly placed on the mounting ring 16, and the bushing can be quickly pulled out by using the impact hammer 3.

[0026] Combined with Figure 2 and attached Figure 5 The pull rod 1 is provided with a section of thread 4, and the pull rod 1 is provided with a moving block 5 connected with a thread. A fixed plate 1 6 and a fixed plate 2 7 are respectively provided on both sides of the moving block 5, and a rotating block 10 is hingedly provided between the fixed plate 1 6 and the fixed plate 2 7.

[0027] Through the above structure, the turning handle 2 is rotated to drive the pull rod 1 to rotate, and the moving block 5 can move up and down to assist in pulling out the bushing.

[0028] Combined with Figure 5 and attached Figure 6 The fixed plate 1 6 is fixedly connected to the moving block 5, the fixed plate 2 7 and the moving block 5 are slidably connected, one side of the fixed plate 1 6 is provided with a fastening bolt 8 extending through the fixed plate 2 7, the rotating block 10 is sleeved on the fastening bolt 8, and the end of the fastening bolt 8 extending to the outside of the fixed plate 2 7 is provided with a threaded butterfly nut 9.

[0029] Through the above structure, the fastening bolt 8 passes through the fixing plate 2 7. With the assistance of the fastening bolt 8 and the butterfly nut 9, the rotating block 10 can be locked, and the overall stability is high.

[0030] Combined with Figure 6 A slider is provided on one side of the fixed plate 7, and a slide groove is provided on both sides of the moving block 5 for cooperating with the slider.

[0031] Through the above structure, the fixed plate 2 7 can be guided by the slider and the slide groove to ensure that it can move smoothly.

[0032] Embodiment 2

[0033] Combined with Figure 3 and attached Figure 4 An extension rod 11 is provided at the bottom end of the rotating block 10, and a sleeve rod 12 for easy adjustment is sleeved on the extension rod 11. A pull block 13 is provided on one side of the sleeve rod 12, and a locking structure is provided between the extension rod 11 and the sleeve rod 12.

[0034] Through the above structure, the extension rod 11 is inserted into the sleeve rod 12, and the extension rod 11 is convenient to stretch and adjust the length. It can be pulled out according to bushings of different thicknesses, and is flexible to use.

[0035] Combined with Figure 4 The locking structure includes a locking bolt 14 inserted into the sleeve rod 12 and the extension rod 11, one end of the locking bolt 14 is provided with a locking nut threadedly connected, and the extension rod 11 is provided with a plurality of limiting holes 15 used in conjunction with the locking bolt 14.

[0036] Through the above structure, due to the multiple limiting holes 15 on the locking bolt 14, the extension length of the extension rod 11 can be flexibly adjusted, which is convenient for use.

[0037] When the utility model is implemented:

[0038] Insert the pull rod 1 into the bushing so that the pull rod 1 is located in the center of the bushing, first rotate the rotating block 10 on one side to drive the extension rod 11 to move so that the pull block 13 on one side is located at the bottom end of the bushing, then rotate the butterfly nut 9, and the fixed plate 2 7 slowly approaches one side of the rotating block 10 under the action of the slider and the slide groove, and continuously locks and fixes the rotating block 10, and then operates the rotating block 10 on the other side in the same way to ensure that the pull blocks 13 on both sides are located at the bottom end of the bushing. The whole is easy to flexibly adjust according to bushings of different diameters, and is convenient to use.

[0039] Then, the pull rod 1 is continuously pulled outward, and the turning handle 2 is used to rotate the pull rod 1. Since the pull blocks 13 on both sides are tightly against the bottom end of the bushing, the moving block 5 can be limited. As the pull rod 1 is continuously rotated, the moving block 5 drives the pull block 13 to move slowly through the extension rod 11 and the sleeve rod 12, and the impact hammer 3 can also be used to continuously knock the turning handle 2 to assist in pulling out the bushing.

[0040] Since the size and thickness of each bushing are different, unscrew the locking bolt 14 and the locking nut, stretch the sleeve rod 12 outward, select the appropriate limiting hole 15, and then pass the locking bolt 14 through the limiting hole 15 and fix it with the locking nut. Bushings of different thicknesses and sizes can be pulled out, which is convenient for covering bushings of all different sizes and shapes, and has strong applicability.

[0041] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0043] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
