Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
As shown in Figures 1 to 6, the bicycle drive shaft 1 for ease of maintenaince includes a beam barrel 2, and the both ends of the beam barrel 2 are set respectively
There are a rolling assembly 3, a clamping head 4 and a locking nut 5, a dismountable locking stock 6, the locking are provided with the beam barrel 2
One end of stock 6 is provided with a locking screw head 7, and the other end of the locking stock 6 is provided with an eccentric washer 8 and a rotatable clamping
Handle 9, the rolling assembly 3 include a fixed seat 31 and some roller balls 32, and the fixed seat 31 includes the retainer plate of an annular
311, the inwall circumference of the retainer plate 311 is provided with some aduncate clamping arcs 312, and the clamping head 4 includes a cylinder
