A flat slider

Abstract

The invention discloses a planar pull head which comprises a pull head body, an elastic piece and a pull piece; the pull head body is provided with an upper fin, a lower fin and a guide column; the elastic piece is provided with a central base part, a locking pawl which is arranged on the rear end of the central base part and a front end part which is arranged on the front end of the central base part; the pull piece is provided with a handle and an eccentric shaft, and the eccentric shaft can be arranged in a space formed by the central base part and the upper fin and is hidden by the central base part; the planar pull head is characterized in that the elastic piece also comprises a supporting pawl which is arranged on the front end of the central base part; a T-shaped sink is arranged on the upper fin, i.e. a horizontal groove and a vertical groove are arranged; the front end part is contained in the vertical groove of the T-shaped sink, so that the upper surface of the front end part is level with or lower than the surface of the upper fin; and the supporting pawl is inlaid into the horizontal groove and is collided with the groove wall of the horizontal groove. According to the planar pull head, the problems that wires are clamped, the hands of a user are injured, the elastic force of the elastic piece easily loses effect and the like in daily use can be solved, and the planar pull head has the advantages of simplicity in structure, convenience in processing and assembly and the like.
