Handlebar grip

A handlebar grip comprising:

• an outer tube of a cylindrical shape, which is made from a plastic material and provided with an open end and a closed end;
• an inner tube of a cylindrical shape, which is made from a plastic material and axially extends from an inner surface of the closed end of the outer tube towards the open end of the outer tube at a predetermined length;
• the inner tube having an outer diameter smaller than an inner diameter of the outer tube such that an annular space is defined between the inner and outer tubes and configured to receive a section of a bicycle handlebar that is inserted through the open end of the outer tube into the handlebar grip;
• the inner tube having a plurality of guide slots axially extending from a free end of the inner tube, and an inner guide surface extending from the free end of the inner tube towards the other end of the inner tube at a predetermined length with a gradually decreased diameter;
• an elongated bolt having a head and a threaded shank axially extending from the head and penetrating through the closed end of the outer tube into the inner tube;
• a wedge-shaped member having a proximity end, a distal end having a diameter greater than that of the proximity end, a circumferential surface configured to be matched with the inner guide surface of the inner tube, and a plurality of ribs on the circumferential surface;
• and
• a threadedly connecting structure for threadedly connecting the wedge-shaped member with the threaded shank of the elongated bolt in a way that the wedge-shaped member is located inside the outer tube, the distal end of the wedge-shaped member faces the open end of the outer tube, and the ribs of the wedge-shaped member are respectively inserted in the guide slots of the inner tube;
• whereby when the elongated bolt is rotatably driven to be tightened up, the wedge-shaped member is driven to move along the inner guide surface of the inner tube into the inner tube to squeeze a circumferential wall of the inner tube to expand outwardly, such that the section of the handlebar, which is located in the annular space, is clamped between the inner tube and the outer tube.
