[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] Please also read Figures 1 to 5 The fuel injector disassembly tool provided by the utility model is now described. The fuel injector disassembly tool comprises a clamping seat 10, a connecting frame 20 and a pulling piece 30. The clamping seat 10 has a first clamping portion 14 and a second clamping portion 15 which are arranged opposite to each other. The first clamping portion 14 and the second clamping portion 15 cooperate to clamp the outer peripheral surface of the fuel injector. The connecting frame 20 is connected to the clamping seat 10. The pulling piece 30 is connected to the side of the connecting frame 20 which is away from the clamping seat 10.

[0029] Compared with the prior art, the fuel injector disassembly tool provided in this embodiment can be connected to the fuel injector by clamping the first clamping part 14 and the second clamping part 15 on the outer periphery of the fuel injector when the fuel injector needs to be disassembled. The connecting frame 20 can make a certain distance between the puller 30 and the clamping seat 10, which is convenient for applying force. The operator pulls the puller 30 to remove the fuel injector. Traditional fuel injectors are difficult to disassemble. After the fuel injector disassembly tool of the utility model connects the clamping seat 10 with the fuel injector, the puller 30 can be pulled out to avoid direct operation on the fuel injector, protect the integrity of the fuel injector, and reduce the difficulty of operation during the removal of the fuel injector.

[0030] In some embodiments, a specific implementation of the above-mentioned card socket 10 can be as follows Figures 1 to 3 See the structure shown. Figures 1 to 3The clamping seat 10 includes a first rod 11, a second rod 12 and a third rod 13 in the same plane. The second rod 12 and the third rod 13 are respectively fixed to the two ends of the first rod 11, and the distance between the second rod 12 and the third rod 13 gradually increases in the direction away from the first rod 11. When connecting the clamping seat 10 and the fuel injector, the second rod 12 and the third rod 13 are sleeved on the outer periphery of the fuel injector, and then the first rod 11 is pushed in the radial direction of the fuel injector until the second rod 12 and the third rod 13 clamp the fuel injector. At this time, the connection between the clamping seat 10 and the fuel injector is completed, and the disassembly process of the fuel injector can be operated by the puller 30.

[0031] Specifically, the second rod body 12 and the third rod body 13 are both located on the first side of the first rod body 11, and the thickness of the first rod body 11 gradually decreases in the direction away from the first side. The cross section of the first rod body 11 is rectangular, and since its thickness gradually decreases in the direction away from the first side, when the fuel injector is difficult to disassemble, the second side of the first rod body 11 (the opposite side of the first side) can be inserted into the bottom of the peripheral step of the fuel injector, and by knocking the second rod body 12 and the third rod body 13 away from the first rod body 11, the first rod body 11 can push out a part of the fuel injector, and the fuel injector is easier to disassemble at this time, and then the first clamping part 14 and the second clamping part 15 are fixed to the fuel injector with reference to the above disassembly process before the disassembly process is carried out.

[0032] In some embodiments, a specific implementation of the above-mentioned connecting frame 20 can be as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 The connecting frame 20 includes two columns 21, the bottom ends of the two columns 21 are respectively connected to the middle of the second rod body 12 and the middle of the third rod body 13, and the top ends of the two columns 21 are fixed to the drawing member 30. That is, the bottom end of one column 21 is fixed to the middle of the second rod body 12, and the top end is fixed to the drawing member 30; the bottom end of the other column 21 is fixed to the middle of the second rod body 12, and the top end is fixed to the drawing member 30.

[0033] The connecting frame 20 of this embodiment has a simple structure and low manufacturing cost, and the space between the two columns 21 can facilitate operators to pull the pulling member 30 to avoid interference.

[0034] In some embodiments, an improved embodiment of the above-mentioned puller 30 can be adopted as follows Figures 1 to 3 See the structure shown. Figures 1 to 3 The drawing piece 30 includes two gaskets 31, which are respectively sleeved on two columns 21, and the gaskets 31 are welded to the corresponding columns 21. The gasket 31 has a central control. Before welding the gasket 31 and the column 21, the gasket 31 can be sleeved on the outer periphery of the column 21, and the distance between the drawing piece 30 and the clamping seat 10 can be adjusted according to the actual use situation, and then welded and fixed after the adjustment is completed.

[0035] In some embodiments, a modified implementation of the above-mentioned card socket 10 can be adopted as follows Figures 4 to 5 See the structure shown. Figures 4 to 5 The clamping seat 10 includes a rotating shaft 16 and a torsion spring 17 sleeved on the rotating shaft 16. The first clamping portion 14 and the second clamping portion 15 are both rotatably connected to the rotating shaft 16. The torsion spring 17 has a pre-tightening force that makes the first clamping portion 14 and the second clamping portion 15 approach each other. The structure of the clamping seat 10 of this embodiment is convenient for installation, and the openable first clamping portion 14 and the second clamping portion 15 can also adapt to the disassembly process of various specifications of fuel injectors, and has a wider range of applications.

[0036] In order to prevent the first clamping portion 14 and the second clamping portion 15 from opening during the process of disassembling the fuel injector, a locking ring 19 may be installed at one end of the first clamping portion 14 and the second clamping portion 15 facing away from the rotating shaft 16 .

[0037] Specifically, the first clamping part 14 and the second clamping part 15 have arcuate surfaces 18 adapted to the outer peripheral surface of the fuel injector. After the first clamping part 14 and the second clamping part 15 clamp the fuel injector, the arcuate surface 18 fits the outer peripheral surface of the fuel injector, and the connection relationship with the fuel injector is more stable.

[0038] correspond Figure 4 In the illustrated embodiment, the connecting frame 20 is respectively hinged to the clamping seat 10 and the pulling member 30. The connecting frame 20 can still use two columns 21, and the bottom end of each column 21 is hinged to the clamping seat 10, and the top end is hinged to the pulling member 30, which can adapt to the change of the position of the first clamping part 14 and the second clamping part 15 when they are opened or closed.

[0039] In some embodiments, a specific implementation of the above-mentioned puller 30 can be as follows Figures 4 to 5 See the structure shown. Figures 4 to 5 The pulling member 30 is a handle 32 fixedly connected to the connecting frame 20 .

[0040] As a variant implementation, see Figures 1 to 3 The pulling member 30 includes a nut 33 connected to the connecting frame 20 and a screw rod 34 threadedly matched with the nut 33 .

[0041] In the two ways of pulling the member 30 , the operator can remove the fuel injector by pulling the handle 32 or the screw 34 .

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
