VARIABLE LENGTH SHAFT AND GRIP

摘要

A variable length shaft assembly comprising a shaft, a shaft adapter, a grip sleeve, an actuator screw, a grip, and a screw is disclosed herein. The grip is bonded to the grip sleeve, the shaft adapter is bonded to the shaft, and the shaft adapter comprises a keyed portion that mates with a keyed structure inside of the grip sleeve. The actuator screw comprises external threads that mate with internal threads inside the grip sleeve, and the location of the actuator screw within the grip sleeve can be adjusted with a wrench. Once the actuator screw is at a desired location within the grip sleeve, the shaft is semi-permanently fixed to the grip sleeve by releasably affixing the keyed structure of the shaft adapter to the actuator screw with the screw. The overall length of the assembly can be adjusted and fine-tuned using these structures.
