Description
Technical field
Spanner field is the utility model is related to, more particularly to a kind of fuel injector tightening tool.
Background technology
Since the cylinder head cover of fuel injector installation site is high-pressure oil pipe joint, sensor on groove structure, and fuel injector
The influence of plug receptacle.When being installed to fuel injector, it is with reference to Chinese Patent Application No.：201120062563.5 it is a kind of multi-functional
Spanner, the spanner generally flat construction, its clamp nut to fuel injector can be with above-mentioned factors when tighten installation
Interference is produced, causes installation to be smoothed out, and installation quality is difficult to be protected.
The disclosure of background above technology contents is only used for design and the technical solution that auxiliary understands the utility model, it is not
The prior art of present patent application is necessarily belonged to, shows the applying date of the above in present patent application in no tangible proof
In the case of disclosed, above-mentioned background technology should not be taken to the novelty and creativeness of evaluation the application.
Utility model content
The utility model aim is to propose not produce interference when a kind of installation fuel injector tightens clamp nut while ensure
The fuel injector tightening tool of installation quality, not smooth to solve above-mentioned installation existing in the prior art, installation quality is difficult to ensure
Technical problem.
For this reason, the utility model proposes a kind of fuel injector tightening tool, including：Clamp, connecting plate and handle, the connection
Plate lower end connects clamp, and the connecting plate upper end connects handle, and the handle end includes boss, and the boss opens up square groove.
Preferably, the clamp symmetrical center line and connecting plate symmetrical center line formation angle, the 20 °≤α of angle≤
40°。
Preferably, the angle is 30 °.
Preferably, the connecting plate is with being connected handle vertical connection.
Preferably, the connecting plate is arc-shaped.
Preferably, the clamp opens up the quadrangle running-on to match with fuel injector clamp nut.
Preferably, the square groove side wall sets groove.
The beneficial effect that the utility model is compared with the prior art includes：(1) the utility model is provided with arc-shaped company
Fishplate bar has been effectively shielded from fuel injector installation site cylinder head cover, and high-pressure oil pipe joint on fuel injector, sensor plug receptacle
Influence, tightened so as to smoothly fix fuel injector, ensure that installation quality.(2) during clamp symmetrical center line and connecting plate are symmetrical
The linear angled angle of the heart, can obtain the distance of tightening of bigger when being tightened using instrument, number is pulled in saving, improves life
Produce efficiency.

Embodiment
With reference to embodiment and compare attached drawing the utility model is described in further detail.It should be emphasized that
It is, what the description below was merely exemplary, rather than in order to limit the scope of the utility model and its application.
With reference to the following drawings, non-limiting and nonexcludability embodiment will be described, wherein identical reference numeral represents
Identical component, unless stated otherwise.
Embodiment 1
A kind of fuel injector tightening tool, including：Clamp 1, connecting plate 2 and handle 3, clamp 1 connect 2 lower end of connecting plate, even
2 upper end vertical connection handle 3 of fishplate bar；3 end of handle includes boss 4, and the boss 4 opens up square groove 5, on 5 side wall of square groove
Groove 7 is set；1 symmetrical center line of clamp forms angle 6 with 2 symmetrical center line of connecting plate, this specific embodiment corner dimension is
20°；Connecting plate 2 is designed as the arc-shaped similar to fuel injector side wall, its height is determined by the interference point on fuel injector；Clamp 1
Open up the quadrangle running-on 11 to match with fuel injector clamp nut.Fuel injector tightening tool twists fuel injector clamp nut
When tight, the clamp 1 of tightening tool is smoothly first blocked into clamp nut, holds the handle 3 of tightening tool, while towards the side of tightening
To firmly pull tightening tool until fuel injector clamp nut install it is firm.
3 end of handle further includes bar 8, and 8 one end of bar is quadrangular 81, and one end is hexagonal prisms 82；Square groove 5 sets groove
7, quadrangular 81 opens up ball 83, and 81 end of quadrangular is inserted into square groove 5, and ball 83 fixes bar 8 with 7 screens of groove.Measurement
Bar 8 is first fixed into square groove 5, is connected using torque spanner by fuel injector tightening tool to the torque size of fuel injector clamp nut
82 end of hexagonal prisms of narrow bars bar 8, then smoothly blocks clamp nut by fuel injector tightening tool clamp 1, holds measuring wrench
Measure so as to obtain torque size.In addition, it is also possible to which torque spanner directly puts square groove 7 into, measures fuel injector tightening tool
Torque size when being tightened to fuel injector clamp nut.
Embodiment 2
The unique of specific embodiment 2 and specific embodiment 1 difference lies in corner dimension is 30 °.
Embodiment 3
The unique of specific embodiment 3 and specific embodiment 1 difference lies in corner dimension is 35 °.
