Dynamic output shaft, is furnished with installation bolt on the housing around the power output shaft of the motor, the fueling injection equipment include worm screw with
And oil pump, the worm screw has axis hole, and the oil pump has and drives turbine, and the worm screw and the driving turbine match, the fueling injection equipment
Also include a support, the support includes a sleeve, and the sleeve lining is provided with a step, and the worm screw is rotatable to be stuck in the sleeve
It is interior, meanwhile, the support also includes an installation cavity, and the oil pump is fixed in the installation cavity, and the installation cavity and the sleeve are adjacent, should
Installation cavity is connected with the sleeve by a gap, and the worm screw and the driving turbine realize power connector in the opening position, and, should
Support is provided with the fixing hole matched with installation bolt, and the axis hole is arranged on the power output shaft for being fixed on the motor.
The avris of the oil pump is provided with installing hole, and the screw corresponding with installing hole is provided with the installation cavity.
The invention has the advantages that compared with the prior art,：
Registration, versatility is preferable.When in use, the position between all parts is more steady for the fueling injection equipment of the present invention
Fixed, the position especially between worm screw and driving turbine is relatively stable, makes power transmission relatively stable and continuous.Simultaneously, it is only necessary to
By the worm set in the sleeve and sleeve of fueling injection equipment on the power output shaft of motor, you can the moment of torsion of the axle that outputs power
It is transferred to worm screw, and realizes the installation of oil pump, so that oil pump has wider use range, a few will not be only limitted to
The instruments such as the electric chain saw of type, extremely convenient.
Description of the drawings
With reference to the accompanying drawings and examples the present invention is further described：
Fig. 1 is the three-dimensional exploded view of the fueling injection equipment in use state of embodiments of the invention；
Fig. 2 is the three-dimensional exploded view of the fueling injection equipment of embodiments of the invention.
Specific embodiment
Embodiment, as shown in Fig. 1 and Fig. 2：Fueling injection equipment, on electric chain saw.The electric chain saw includes housing 100, should
Motor 200 is provided with housing 100, the motor has power output shaft 201.Power on the housing 100 around the motor 200 is defeated
Shaft 201 is furnished with installation bolt 300.Such as, the power output shaft 201 on the housing 100 around the motor 200 is provided with screw,
Screw accesses those installation bolts 300 for Luo.Installation bolt 300 can be equally distributed 3.
Concretely, the fueling injection equipment includes worm screw 10 and oil pump 20.The worm screw 10 has axis hole 11, and the oil pump 20 has
There is driving turbine 30, the worm screw 10 and the driving turbine 30 match.That is, the driving turbine 30 makes the oil spout of oil pump 20 after rotating,
And the driving turbine 30 and the worm screw 10 form worm-and-wheel gear.
Further say, the fueling injection equipment also includes a support 40.The support 40 includes a sleeve 41.The inwall of sleeve 41
A step 411 is provided with, the worm screw 10 is rotatable to be stuck in the sleeve 41.Such as, the internal diameter of the sleeve 41 is substantially corresponded to
The external diameter of the worm screw 10, and a side of the worm screw 10 withstood on the step 411, so that the worm screw 10 is stuck in the sleeve 41
It is interior.Meanwhile, the support 40 also includes an installation cavity 42.The oil pump 20 is fixed in the installation cavity 42.The installation cavity 42 and the set
Cylinder 41 is adjacent, and the installation cavity 42 is connected with the sleeve 41 by a gap 43, and the worm screw 10 and the driving turbine 30 are in the gap
