Detailed Description
The following detailed description of the present invention is made with reference to the accompanying drawings.
As shown in fig. 1 to 5, in the embodiment of the present invention: a high-strength bicycle handlebar 4 fixing head comprises a connecting head 1, a frame connecting rod 2 and a detachable fastener 3, wherein the connecting head 1 comprises a shaft fork 11 and a shaft fork 11 cap 12, the tops of fork branches at the left end and the right end of the shaft fork 11 are respectively provided with a shaft fork 11 lug and a shaft fork 11 hole formed in the shaft fork 11 lug, and the shaft fork 11 cap 12 is provided with a shaft fork 11 cap 12 hole corresponding to the shaft fork 11 hole; the lower end part of the handlebar 4 is put into a fork opening of the shaft fork 11, a cap 12 of the shaft fork 11 covers the upper end part of the handlebar 4 and aligns a hole 12 of the cap 12 of the shaft fork 11 with a hole of the shaft fork 11, and the detachable fastener 3 is screwed between the hole 12 of the cap 12 of the shaft fork 11 and the hole of the shaft fork 11 so as to lock the handlebar 4; the frame connecting rod 2 is of a pipeline structure, the inner surface of the frame connecting rod is provided with a reinforcing rib 21, the bottom rod 13 arranged at the lower end part of the shaft fork 11 is embedded into the inner surface of the frame connecting rod 2 and is tightly clamped on the reinforcing rib 21, and the detachable fastening piece 3 is penetrated and fastened on the frame connecting rod 2 and the bottom rod 13.
