Seat post lifting control device

Abstract

This invention provides a seatpost lifting control device, including a bearing, a base, a handle, a bushing, a washer, and a locking element. The pivot section of the handle blocks the mounting slot of the base, and the first and second lugs of the base block the bearing located within the pivot section, preventing external dirt from entering the receiving groove and the bearing. This invention maintains smooth operation and significantly extends maintenance intervals and product lifespan.
