First connecting rod includes positioning disk and first connecting rod ontology, and the positioning disk is connect with first connecting rod ontology, the front fork
Bottom is provided with locating slot, and the positioning trench bottom is provided with connecting hole, and the positioning disk and locating slot are cooperatively connected, and described the
One connecting rod body sequentially passes through connecting hole and sleeve is connect with nut cap.
Further, the fixing piece further includes the second connecting rod；The first connecting rod ontology is hollow structure, institute
The one end and positioning disk press for stating the second connecting rod connect, and the other end passes through positioning disk and first connecting rod ontology and nut cap connects
It connects.
Further, the inner cavity of the first connecting rod ontology is provided with several grooves, and connecting in the groove has
Storm-cone, the storm-cone and the press of the second connecting rod connect.
Further, the nut cap is provided with inner ring and outer rings, and the inner surface of the inner ring and outer rings is provided with screw thread,
The first connecting rod ontology is connected through a screw thread with outer ring, and second connecting rod is connected through a screw thread with inner ring.
Further, the screw thread of the interior ring inner surface and the thread rotary orientation of outer ring inner surface are opposite.
Further, the positioning disk is kidney-shaped.
The utility model has the advantages that the beneficial effects of the utility model are as described below: a kind of front fork front component of electric bicycle is set
It is equipped with first connecting rod and the second connecting rod, the first connecting rod and the second connecting rod are connect with nut cap, but the two
Connection screw thread it is oppositely oriented, i.e., after the second connecting rod must be detached from nut cap, nut cap and first connecting rod generate loosen it is de-
From before, and the second connecting rod be detached from nut cap after can't be that front fork is separated with wheel, dual link is more reliable；When the second connection
If bar and nut cap from rear, can separate, due to the press without the second connecting rod, storm-cone will be rolled freely with first connecting rod
It is dynamic, so that mutually collision generation abnormal sound reminds driver, thus before first connecting rod and nut cap are detached from, play early warning
Effect.

Specific embodiment
The utility model is further described with reference to the accompanying drawing.
A kind of front fork front component of electric bicycle as described in attached drawing 1 to 6, including front fork 1, front-wheel 2 and fixing piece
3；The front-wheel 2 is rotatably connected by fixing piece 3 in the bottom of front fork 1；
The fixing piece 3 includes sleeve 301, first connecting rod 302 and nut cap 303；The axis of the sleeve 301 and front-wheel 2
Inner ring is held to be connected, the first connecting rod 302 includes positioning disk 304 and first connecting rod ontology 305, the positioning disk 304 with
First connecting rod ontology 305 connects, and 1 bottom of front fork is provided with locating slot 101, and 101 bottom of locating slot is provided with company
Hole 102 is connect, the positioning disk 304 is cooperatively connected with locating slot 101, and the first connecting rod ontology 305 sequentially passes through connecting hole
102 and sleeve 301 connect with nut cap 303.The front fork 1 is fixed between sleeve 301 and positioning disk 304.
The fixing piece 3 further includes the second connecting rod 306；The first connecting rod ontology 305 is hollow structure, described
Positioning disk 304 is provided with intercommunicating pore 311, and intercommunicating pore 311 is communicated with the inner cavity of first connecting rod 306, and the one of the second connecting rod 306
End is connected with the press of positioning disk 304, and the other end passes through through-hole 311 and first connecting rod ontology 305 is connect with nut cap 303.
The inner cavity of the first connecting rod ontology 305 is provided with several grooves 307, and connecting in the groove 307 has
Storm-cone 308, the storm-cone 308 and the press of the second connecting rod 306 connect.
In the present embodiment, storm-cone 308 is steel ball, and the diameter of storm-cone 308 is less than the diameter of intercommunicating pore 311, to protect
When the second connecting rod 306 is fallen, storm-cone 308 will not be fallen card from intercommunicating pore 311.
The nut cap 303 is provided with inner ring 309 and outer ring 310, and the inner surface of the inner ring 309 and outer ring 310 is respectively provided with
