The technical scheme that its technical matters that solves the utility model adopts, it comprises the main body tapered rod that is fixed on the bicycle taper pipe, handlebar stem and gloves, the two ends of described main body tapered rod are arranged with the taper connection head, each taper connection head is hinged with guide finger by locating dowel pin, the end of guide finger is fixed with stop collar, be arranged with handle tapered rod on the taper connection head with tapering, handlebar stem is captiveed joint with the handle tapered rod after entangling guide finger, the cavity internal fixation restraining position ring block of handlebar stem, on the guide finger between spacing ring and the stop collar, be arranged with retracing spring, the internal diameter of spacing ring is less than the external diameter of stop collar, afterbody at the taper connection head is provided with elastic lock, is provided with lockhole with the cooresponding handle tapered rod of elastic lock.
Described taper connection head is provided with position-limited trough, and the handle tapered rod is provided with the notch that matches with position-limited trough.
Described elastic lock is made up of hoodle, spring and screw, and hoodle and spring are installed in behind the mounting hole of taper connection head successively by the screw capping.
After adopting said structure, following advantage and effect are arranged compared with the prior art:
1, the utility model since handlebar stem by adopting same taper fitting between handle tapered rod and the main body tapered rod, thereby the gap that can eliminate handlebar stem, thereby the comfort level and the safety in utilization of raising cycling.
2, after the employing taper fitting technology, bicycle handle part quality of fit is improved, thereby also improved the folding property of bicycle folding handle, and it is more laborsaving, convenient that the user is folded up.
3, the actual product processing shows, adopts the utility model technology not only can make processing, assemble conveniently, and can obviously reduce cost of product.

The specific embodiment
Fig. 1 is to shown in Figure 4, specific embodiments for the utility model bicycle folding handle, it comprises main body tapered rod 2, handlebar stem 3 and gloves 4, bicycle taper pipe 1 is fixed on the cycle frame, taper bar cramp 11 is fixed on the bicycle taper pipe 1, main body tapered rod 2 is fixed on the taper bar cramp 11 by screw 12, the two ends of described main body tapered rod 2 are arranged with taper connection 22, each taper connection 22 is hinged with guide finger 61 by locating dowel pin 21, the end of guide finger 61 is fixed with stop collar 62 by screw 64 and pad 63, be arranged with handle tapered rod 31 on the taper connection 22 with tapering, handlebar stem 3 entangles guide finger 61 and captive joint with handle tapered rod 31 in stop collar 62 backs, the cavity internal fixation restraining position ring block 32 of handlebar stem 3, spacing ring 32 is movably set on the guide finger 61, on the guide finger 61 between spacing ring 32 and the stop collar 62, be arranged with retracing spring 65, the internal diameter of spacing ring 32 is less than the external diameter of stop collar 62, spacing ring 32 can not deviate from from guide finger 61, afterbody in taper connection 22 is provided with elastic lock 5, is provided with lockhole 33 with elastic lock 5 cooresponding handle tapered rods 31.Described elastic lock 5 is made up of hoodle 53, spring 52 and screw 51, and hoodle 53 and spring 52 are installed in behind the mounting hole of taper connection 22 successively by screw 51 cappings.
For convenience folding location, described taper connection 22 is provided with position-limited trough 71, and handle tapered rod 31 is provided with the notch 34 that matches with position-limited trough 71.
Folding step of the present utility model is summarized as follows:
Folding step 1: with holding tight handlebar stem 3 or handle tapered rod 31 or gloves 4, press...with one's finger press hoodle 53 after, pull handle bar 3 makes the lockhole 33 of handle tapered rod 31 break away from the locking of hoodles 53, as shown in Figure 5.
