Abstract

The invention discloses a straight-locking riser, which comprises a base and an upper cover. The base has a clamping part, two extension parts and two first perforations respectively arranged in the extension parts. The clamping part has a A lower groove with a concave surface, a lower concave arc surface located in the lower groove, two second perforations on the lower concave arc surface and four screw holes on the top surface, two first screws are respectively installed on the first Perforated and screwed to a shoulder cover fixed to a vertical pipe, two second screws are respectively pierced through the second perforation and screwed to the shoulder cover, the upper cover has an upper groove recessed from its bottom surface, and one is located in the upper groove The inner upper concave arc surface and the four third perforations on the bottom surface, the four third screws are respectively installed in the third perforation holes and screwed to the screw holes respectively, so that a handle is clamped on the upper and lower concave arc surfaces. space; therefore, the straight-lock seat tube allows the bicycle to have good handling and stability.

Description

technical field [0001] The present invention relates to bicycle stems, and more particularly to a direct mount stem. Background technique [0002] see figure 1 and figure 2 , the existing direct lock riser 10 mainly includes a base 11 and an upper cover 12, the base 11 has a clamping portion 112, and two fixing portions 114 integrally extending from the clamping portion 112 . The upper cover 12 is fixed to the clamping portion 112 by four screws 13 for clamping and fixing a grip bar 14 of the bicycle between the upper cover 12 and the clamping portion 112 . The two fixing parts 114 are fixed to a front fork crown 16 (fork crown) of the bicycle by four screws 15 . The front fork crown 16 is affixed to a vertical tube 17 and two shock absorbers 18 of the bicycle, and then indirectly affixed to the front wheel (not shown) of the bicycle. Therefore, the user can control the bicycle through the grip bar 14 The front wheel of the bicycle. The straight-lock riser 10 is mostl...
