Adjustable brake assembly

Abstract

This invention provides an adjustable braking assembly comprising a main body, a grip, and a grip distance adjustment module. One end of the main body has a vehicle body connection portion, and the other end has a pivot hole and abutment protrusion. One end of the grip has a pivot portion and a grip screw hole, the pivot portion and the pivot hole being pivotally connected by a fixing pin assembly, allowing the grip to pivot relative to the main body. The grip distance adjustment module includes an adjustment rod, an adjustment member, and a positioning member. A first screw portion of the adjustment rod is disposed in the grip screw hole, and a second screw portion has a receiving groove. The adjustment member has an adjustment screw hole and a plurality of positioning portions abutting against the abutment protrusion. The positioning member is disposed in the receiving groove and has an elastic telescopic portion, which selectively engages with one of the positioning portions. This allows the grip distance between the grip and the main body to be adjusted and stably positioned, thereby improving the operating comfort and braking control stability for different users.
