Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
Referring to Fig. 4-8, a kind of multi-functional clamp of fuel injector lid processing, it includes cylinder 1, alignment pin 2 and locking screw
Nail 3.
Wherein, the end face of cylinder 1 is positioning inclined-plane 11, and the positioning inclined-plane 11 is used for the lower surface of socket part 42 in fuel injector lid
Cooperation is adjacent to.
Specifically, the angle at the positioning inclined-plane 11 and the center of cylinder 1 is a, itself and upper connecting part center and middle socket part center it
Between angle a it is equal.
Wherein, the center of positioning inclined-plane 11 is provided with the first location hole 111, the center line of the first location hole 111 with it is described
Positioning inclined-plane 11 is mutually perpendicular to, and first location hole 111 is used for fuel injector lid lower connecting part 41 and inserts positioning.
Wherein, two the second location holes 112 and two locking screw holes 113 are additionally provided with the positioning inclined-plane 11；Described
Two location holes 112 are built with alignment pin 2；The alignment pin 2 covers positioning in isometrical hole 424 for inserting fuel injector；This two
