Dual-purpose wrist developer with adjustable arm of force

Abstract

The invention discloses a dual-purpose wrist developer with an adjustable arm of the force. Extension rods are symmetrically arranged at two ends of a compression spring, the extension rods are fixedly connected with the compression spring, limiting rings are arranged on the outer rings of the extension rods, electronic pushing rods are arranged at the lower ends of the limiting rings, connectingheads are arranged at the tops of the electronic pushing rods, the top surfaces of the connecting heads are fixedly welded to the extension rods, extended rods are arranged at the bottoms of the connecting heads, the input ends of the extended rods are provided with controllers, and two ends of the extended rods are connected with the connecting heads and the controllers. According to the wrist developer, the displacement range of the extension rods can be effectively limited by the limiting rings, so that the compression spring is effectively protected from malfunction due to excessive deformation, the extending and shortening of the extended rods can be controlled by the controller, so that the effect of adjusting the arm of the force is achieved, when the extending lengths of the extended rods reach the maximum amount, the whole device can be used as an arm power exercising apparatus, the flexibility degree of the whole device is strengthened, and the structural practicability is improved.
