It is distributed in the one end for key of riving；Arc groove connects two oblique angles.Handle one end and key connection of riving, the other end have screw rod；And
There is tup screwed hole to be used to be connected with the screw rod of handle；Key of wherein riving has shovel angle at an angle.
Preferably, in above-mentioned technical proposal, the other end for key of riving similarly has fish mouth type structure.
Preferably, in above-mentioned technical proposal, one end of handle also has flat position, is provided with U-type groove on flat position, has in U-type groove
There is the through hole in vertical handle axle center, screw is connected through through hole with a screw of key of riving, and the key that will rive is fastened on U-type groove
It is interior.
Compared with prior art, the utility model has the advantages that：
1. spreading jump ring is responsible at symmetrical oblique angle.Offset from mounting hole but do not depart from mounting groove.Arc groove makes oblique angle can be with
It is smaller, rapid operation.Arc groove can be centered at fuel injector axis simultaneously, make jump ring spreading symmetry more preferable.
2.U type grooves are opened on flat position, and key of riving is installed on U-type groove.Key of riving is double end, interchangeable, can extend use
Cycle.
3. shoveling angle pad on fuel injector solenoid housing, facilitate tilt operation.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in figure 1, a kind of jump ring spreading punch device 100 provided by the utility model is mainly by key 1 of riving, handle 2,
Tup 3, screw 4 form.One end of key 1 of riving has fish mouth type structure, and fish mouth type structure includes two oblique angles 11 and arc groove 12,
Two oblique angles 11 are symmetrically distributed in the one end for key 1 of riving；Arc groove 12 connects two oblique angles 11.The one end of handle 2 connects with key 1 of riving
Connect, the other end has screw rod 24；And there is tup 3 screwed hole 31 to be used to be connected with the screw rod 24 of handle 2；Wherein rive key 1
With shovel angle 14 at an angle.
