Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As illustrated in fig. 1 and 2, a kind of cycle frame, the mobile jib 2 and master of handlebar hand cradle 1 and the welding of handlebar hand cradle 1 are included
The support bar 4 and two links 7 for being symmetrically connected to plane both sides residing for mobile jib 2 and support bar 4 that bar 2 welds.The company
Connect frame 7 and include being used for connecting the supporting part 71 of mobile jib 2 and support bar 4, extension 72 that the both ends of supporting part 71 extend to wheel 5 with
And the connecting portion 73 of two extensions of connection.As further preferred scheme, between the link 7 and support bar 4 away from
From more than or equal to the distance between the chain wheel 6 on support bar 4 and support bar 4, so as to play a part of protecting chain wheel 6.
Two pieces of symmetrical bearing plates 8 for being used for installing wheel 5 are welded on the connecting portion 73 of the both sides of wheel 5.Pass through the setting of link 7
