Handle shaft for chair

Abstract

The invention discloses a handle shaft for a chair. The handle shaft comprises a handle shaft main body, wherein the handle shaft main body consists of a handheld part, a driving part and a connectingpart for connecting the handheld part with the driving part; an arm strength training mechanism is arranged on the handle shaft main body; the arm strength training mechanism is composed of a force application mechanism and a strength adjusting mechanism, the force application mechanism is arranged on the handheld part, a locking mechanism used for limiting the force application mechanism is further arranged on the force application mechanism, the strength adjusting mechanism is arranged on the driving part, a limiting mechanism is arranged at the end of the driving part, and the force application mechanism and the strength adjusting mechanism are connected through a connecting plate. Through the arranged arm strength training mechanism, arm strength can be trained while the handle shaftis used for driving a massage structure to massage the back, the problem that in the prior art, a handle shaft is single in function is solved, and the practicability is high; the detachable form of the handle shaft main body is achieved through the arranged limiting mechanism, then grip strength training can be achieved through the grip strength training mechanism, and the practicability of the handle shaft is further enhanced.

Description

technical field [0001] The invention relates to a handle shaft, in particular to a handle shaft used for chairs. Background technique [0002] Patent 1: According to "A Manual Massage Chair" disclosed by China Invention (Application No.: CN201410232823.7), it belongs to the technical field of massage device structure.
