Abstract

The invention discloses an adjustable racket handle. The handle comprises a lead screw, an expansion structure, a supporting framework, several inner expansion arc-shaped plates, several outer expansion arc-shaped plates and an elastic sleeve which are sequentially arranged from inside to outside, the expansion structure is driven to expand through rotation of the lead screw, the expanded expansion structure pushes the inner expansion arc-shaped plates and the outer expansion arc-shaped plates to expand outwards through the supporting framework, then the elastic sleeve is driven to expand outwards, and therefore the thickness of the handle can be changed so as to meet the requirements of different crowds for comfort. The handle is wide in adjusting range, reasonable in structure, compact in layout, low in manufacturing cost and suitable for popularization.
