Problems solved by technology
However, in the known technology, the plurality of anti-reverse pieces are separately installed, and only the elastic ring is used to fix the plurality of anti-reverse pieces. Therefore, the plurality of anti-reverse pieces are easy to slide and rotate relative to the supporting part, resulting in uneven force and easy contact. The inner wall of the standpipe is not easy to disassemble due to insufficient friction and is easy to detach

The invention relates to a headset expander of a bicycle. The headset expander comprises an expansion barrel, a packing barrel and a bolt, wherein the expansion barrel comprises a bottom, multiple forcible abutting sheets arranged at the bottom at intervals and a guide connecting section opposite to one end of the bottom, a screw hole penetrates through the bottom, and a containing chamber is defined by the multiple forcible abutting sheets; a penetrating hole penetrates through the packing barrel, the packing barrel comprises a packing section with the outer diameter larger than the span of the containing chamber and an abutting section connected with the packing section, and at least one of the abutting section and the guide connecting section gradually shrinks in the direction of the bottom; the bolt penetrates through the penetrating hole and is fixed to the screw hole in a threaded mode; and the bolt is adjusted, so that when the abutting section is close to the bottom and penetrates into the containing chamber, the packing section forcibly abuts against and expands the multiple forcible abutting sheets in the radial direction.
Description
technical field [0001] The present invention relates to bicycles, and in particular, to a headset expander for bicycles. Background technique [0002] Generally, a bicycle is connected by an expander between the front fork and the stem. The known art dilator includes a cover body, a plurality of anti-return sheets and an elastic ring, one end of the cover body is extended with a supporting portion, the plurality of anti-return sheet rings are arranged on the outer periphery of the abutting portion, and the elastic ring The pieces are sleeved on the outer periphery of the plurality of supporting portions. [0003] In the prior art, the plurality of non-return sheets are pushed against the inner wall of a vertical pipe by the supporting portion. However, in the prior art, the plurality of anti-return plates are arranged separately, and only the elastic ring is used to fix the plurality of anti-return plates. Therefore, the plurality of anti-return plates are easy to slide an...
