During the adjustment of the two support members 52 to the first position P1, the two support members 52 are located below the bottom of the seat body, and are fixed to the upper cover of the engine cylinder head cover. 24, when the two connecting members 51 drive the two supporting members 52 to the second position P2, the two supporting members 52 are away from the two fixing members 24, and further away from the bottom of the base body 4.

Each of the connecting members 51 defines a first segment 511 and a second segment 512. The second segment 512 extends from one end of the first segment 511, and the extending direction of the first segment 511 is perpendicular to the second segment 512. The extending direction is such that each of the connecting members 51 has an L shape. A slot 513 is defined in the end of the second section 512. The slot 513 includes two sidewalls. The two sidewalls respectively define a corresponding through hole, and the two through holes communicate with the slot 513. Each of the connecting members 51 defines an L-shaped groove 514. The L-shaped groove 514 includes a first portion 514a and a second portion 514b. The first portion 514a of the L-shaped groove 514 is along the first segment 511 of each connecting piece. Extension of a section 511 The direction extends and is in contact with the second section 514b of the L-shaped groove 514 at the intersection of the first and second sections 511, 512 of each of the joints, and the second section 514a of the L-shaped groove is further along each joint The extension of the second segment 512 extends, and in brief, the contour of the L-shaped groove 514 corresponds to the contour of the link 51. Moreover, the L-shaped groove 514 does not extend further to the slit 513, that is, the L-shaped groove 514 and the slit 513 form a barrier wall and are not in communication with each other. Each of the connecting members 51 is disposed in the through slot 43 , wherein the two fixing members 53 are slidably disposed in the first hole 14 of the first cross frame 41 , the L-shaped slot 514 of each connecting member and the second horizontal portion The inner hole 421 of the frame 42 is such that each of the connecting members 51 can pivot relative to the seat body 4 around one of the fixing members 53.

Each of the support members 52 includes a beam 521 and two vertical columns 522. Each of the beams 521 defines two sliding slots 521a extending longitudinally and extending through the top and bottom of each beam 521 and adjacent to the longitudinal ends of the beams 521. Preferably, the two sliding slots 521a extend in a lengthwise direction along the length of each of the beams 521, and have a long groove shape. The two fixing members 53 are slidably disposed in the two sliding slots 521a and are fixed to the second sliding slot 521a. The top of the two vertical columns 522 is such that the two vertical columns 522 are slidably disposed at both ends of the bottom of the beam 521. A positioning hole 522a is recessed in the bottom of each vertical column.

The spacing between the two side walls of the slot 513 is substantially equal to the width of the beam, so that the beams 521 can be received in the slot 513, and a through hole is formed in the middle portion of each beam 521. The width direction of the beam is parallel, and runs through the left and right sides of the width direction of each beam 521, one of which is solid The fixing member 53 is fixed to the through hole of the two side walls and the through hole, so that the beam 521 is fixed to the second segment 512 of the connecting member. When the connecting members 51 are pivoted relative to the base 4, the connecting members 51 can drive the supporting members 52 to be displaced between the first position P1 and the second position P2.

When the bracket 1 of the injector detaching device of the engine of the present invention is mounted on the upper cover 2 of the engine cylinder head, first, the two connecting members 51 are respectively wound around the two fixing members 53 with respect to the first and second transverse frames 41 and 42. Pivoting and driving the two supporting members to the first position P1, wherein the beam 521 is located below the bottom of the first and second transverse frames 41, 42 and aligning the positioning holes of the vertical columns 522 respectively In one of the fixing members 24, the longitudinal columns are fixed to the upper cover 2 of the engine cylinder head, and all the fixing members 53 are screwed, as shown in FIG. Finally, the user can erect the fuel injector detaching device 3 on the seat body 4 to complete the assembly of the fuel injector detaching module. After the components of the fuel injector detaching device 3 are inserted through the through groove 43, The operation of removing all the components of the injector 23 from the nozzle housing 22 is started, as shown in FIG.

Referring to FIG. 6, when the bracket is mounted on the cover 2' of the engine cylinder head of other models, since the position of the nozzle (not shown) of the upper cover 2' is low, the seat 4 must be adjusted to Properly positioned, otherwise the injector detaching device will not easily disassemble the injector. The bracket is provided with the L-shaped groove 514 in each of the connecting members 51. Therefore, the user can slide the fixing member 53 that is disposed in the L-shaped groove from the first passage 514a of the L-shaped groove to the second passage 514b. The seat body 4 is slidable relative to the two supporting mechanisms, whereby the seat body 4 can be kept with the fuel injector At an appropriate distance, after the nozzle dismounting device is erected on the seat body, it is easy to remove all the components of the fuel injector.

It is worth mentioning that the through holes 411 and 421 of the first and second cross frames are long holes, and the sliding grooves 521a of the two beams are long grooves, so that the two supporting mechanisms 5 can adjust the distance between each other. And the two longitudinal columns 522 of each support member can also be adjusted to each other, and the bracket is mounted on the upper cover of the engine cylinder cover of different styles.

After all components of the injector 23 have been removed from the nozzle housing 22, the bracket can be removed from the upper cover of the engine cylinder head. Referring to FIG. 5 and FIG. 5A , when the user wants to receive the present invention, firstly, the two connecting members 51 are respectively pivoted around the two fixing members 53 relative to the first and second transverse frames 41 and 42 and drive the two. The support member 52 is displaced around the longitudinal ends of the first and second cross frames 41, 42 to the second position P2, and the beam 521 is located above the top of the first and second cross frames 41, 42. And the entire support member 52 is flatly attached to the top of the first and second cross frames 41, 42, whereby the bracket presents a folded shape for easy storage.

As can be seen from the above, the bracket of the injector detaching device of the engine of the present invention is provided with the two connecting members 51, and the two connecting members 51 can pivot relative to the base 4 to drive the two supporting members 52 to be displaced in the first position. Between P1 and the second position P2, the invention can be conveniently stored, and can be quickly used in use, so that the bracket can be disassembled after the first assembly. It's very convenient, and you don't have to worry about missing components.

Moreover, the bracket can successfully reduce the time of the cover on the engine cylinder head and the storage time, which is quite efficient.

It is worth mentioning that the connecting member 51 of the bracket is provided with the L-shaped groove 514, and the through holes 411 and 421 of the first and second transverse frames are long holes, and the sliding grooves 521a of the two beams are The utility model has the advantages of long groove shape, whereby the invention can be adjusted at multiple angles along an X axis, a Y axis and a Z axis, and the bracket is mounted on the upper cover of the engine cylinder cover of different models.
