[0040] The bearing sleeve 20 is manufactured using a one-piece molding process and includes a support column 21 arranged along its length and a base 24 located at the bottom of the support column 21 and fixedly connected to it. Adjacent support columns 21 are fixedly connected by a connecting ring 22. The support column 21, connecting ring 22 and base 24 together enclose the loading cavity 23.

[0041] A fixing insert 12 is provided on the upper part of the disc body 11, and a fixing hole corresponding to the position of the fixing insert is provided on the bottom surface of the disc body 11. When there are multiple loading discs 10, the upper loading disc 10 is stacked on the lower loading disc 10, and the fixing insert 12 of the lower loading disc 10 is inserted into the fixing hole of the upper loading disc 10, so that the stacked loading discs 10 can be fixed in the horizontal direction, thereby realizing the transfer of multiple loading discs 10 in a single batch and improving the transfer efficiency of the fuel injector housing 100.

[0042] The disk body 11 includes a rectangular support frame 111 and a base plate 112. The base plate 112 is disposed inside the support frame 111 and is fixedly connected to the support frame 111.

[0043] The base plate 112 is provided with a plurality of fixing holes for fixing the bearing sleeve 20, and the bottom of the bearing sleeve 20 is provided with a snap-fit ​​part 25; the bearing sleeve 20 is detachably fixed in the fixing holes through the snap-fit ​​part 25.

[0044] Furthermore, the bottom of the support frame 111 has a short supporting side 19 for supporting the base plate 112.
