Specific embodiment
For the content of the invention of the invention, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing
Describe in detail as follows：
Refering to accompanying drawing 1 to Fig. 3.
Embodiment 1
A kind of withdrawing fuel injector specific purpose tool, is made up of top board, support and central leading screw；Top board is rectangle structure, in
Between leave leading screw advances through hole, two supports are overall with top board in vertical state, and leading screw is in parastate with support, and support is used for solid
It is scheduled on cylinder cap fuel injector fixing bolt as anchor point and stress point, screws in leading screw end and connect with fuel injector top internal thread
Connect, pulled out fuel injector with the relative motion of support using leading screw.
The present embodiment specific implementation process：
Withdrawing fuel injector specific purpose tool, including one piece of 3, two, top board, 4, one, support leading screw 2 and two nuts 5.Top board
Two ends welding support, plays a supportive role, ceiling center perforate and welded nut, and leading screw screws out screw-in, leading screw top from nut
