Support is adjacent to envelope nut, when cutting pin and being locked, there is not gap between support and envelope nut.Therefore cut pin can be well controlled at lock-out state.
The Axis Cross angle, front and rear part of high-speed electric expreess locomotive shell is 20 to 45 °.Ergonomic designs obtains good application at above-mentioned bending area.
A bearing-surface of support is for placing middle finger, and another bearing-surface is for placing thumb.
Support and bearing-surface have good profile.
Envelope nut is preferably configured to supports user finger tip, and is provided with cannelure or similar structure on the surface, makes user catch envelope nut better.
Connector on high-speed electric expreess locomotive can be connected with the air hose of two or more depression, or connects dihedral adapter.
Dihedral adapter preferably can be connected with the air hose of two or more depression.
Connector, dihedral adapter and any two of air hose, link together into as a whole by snap close pin or bayonet lock.
The front cross section of motor housing is less relative to rear portion, and the reason done like this is the more choice refreshments making the axle cap of housing front and accept box making.Because diameter diminishes thus saves weight and cost, do not need angle axle cap yet.
The high-speed electric expreess locomotive design that this utility model provides meets human engineering.For the user, accurately can control high-speed electric expreess locomotive like a cork for a long time, mainly because high-speed electric expreess locomotive has higher speed.The warp architecture of motor housing makes user hand-held high-speed electric expreess locomotive more like a cork, no matter is that user uses left hand or the right hand.High-speed electric expreess locomotive of the present utility model strictly can be controlled and be kept stable in the hands of user simultaneously.Due to the overall structure weight saving of motor housing, thus reduce manufacturing cost.Several case members that can be replaced are connected to each other, and form a single monolithic case.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model will be further described.
As a kind of embodiment of the present utility model, consult Fig. 1, a kind of high-speed motor, comprise shell 1a, shell 1, and shape has a certain degree between the two.Compared to the cross section at shell 1 rear portion, the cross section of shell 1a front portion seems less, and entirety presents the trend of taper.The angle of nearly 30 ° between motor casing 1 and shell 1a, can reach better balance in such user's use procedure.No matter user uses left hand or the right hand.
Can clearly see in the diagram, support 4 is arranged on the front end of shell 1a, is mainly convenient to user's hand-held.Support 4 comprises two bearing-surfaces 10,11, can extend to another side, and edge has carried out chamfered from a wherein bearing-surface.In actual use procedure, thumb is placed on supporting surface 10, middle finger is placed on bearing-surface 11 simultaneously, and forefinger is placed on the upper surface of support.Such finger just can easily be arranged and stable high-speed electric expreess locomotive muchly.The below of center of gravity just in time between thumb and forefinger of motor.Support is specially designed to have symmetrical structure, is convenient to the placement of thumb and middle finger.Wherein supporting portion is in the front end of shell, roughly in bending vicinity.
In addition at case nose, support 4 is connected to locking mechanism, accepts box 7 and cut pin 8 for locking.Accepting box 7 can with locked under demountable mode, and the cutting pin 8 of insertion can the locking and unlocking easily.In order to this object, support portion 4 can be replaced, and is effectively connected with this locking mechanism.At intra-operative by replacing support, can change and cut pin 8.
As can be seen from Figure 1, shaft-cup 2 and envelope nut 3 are for guiding and covering described cutting pin.Envelope nut 3 and supporting surface 10,11 upper surface profile have all carried out safe handling, and envelope nut 3 is screwed to the front end of shell 1a, thus is fixed.At cutting pin 8 in the locked state, support 4 and adjacent envelope nut 3 couple together in gapless mode.
Fig. 1,2,3 and 5 can see, the connector 6 of this utility model high-speed electric expreess locomotive, for joining power line 5.
From the cross-sectional view of Fig. 4 support, can find out that support has the shape of similar isosceles triangle.It is installed in case nose, and rotate and transverse shifting for preventing, when latched position, it is by spring preload.
Envelope nut 3 is also designed to be convenient to hand-held handle, for reaching this object, devises cannelure its outer placing, and at the bearing-surface 10 of support 4, also devises cannelure on 11.
The diameter of shell 1a front portion is less than 15 millimeters, so that more easily control the running of all spindle guide plates, such overall weight is lighter, more cheaply, and operates and becomes easier.Because there is no extra stop mechanism, there is no extra helical gear yet.
In order to enter narrow and darker place, need high-speed electric expreess locomotive to make Curved.And also need to bend at its rear portion, can be achieved the goal by the adapter connecting certain angle.When deep operation, the high-speed electric expreess locomotive with human engineering can control motor running by the rear portion holding high-speed electric expreess locomotive.Additional adapter has certain bending, and can connect air supply hose or electrical connection cable, also can connect both simultaneously.
