The invention discloses a split type torsion spring jack. The split type torsion spring jack comprises a hole sleeve, a torsion spring, a variable-diameter bundle piece and a top cover, wherein an annular table is arranged on the inner wall of one end of the hole sleeve, the torsion spring is of a cylindrical structure, a concave waist-narrowing part is arranged in the middle of the torsion spring, the torsion spring is inserted into the hole sleeve, one end of the torsion spring abuts against the annular table, the variable-diameter bundle piece is tightly arranged outside the waist-narrowing part in a sleeving mode, a gap is reserved between the inner wall of the hole sleeve and the reducing bundle piece, and the top cover is of a hollow structure, covers the other end of the hole sleeve and abuts against the other end of the torsional spring. According to the split type torsion spring jack provided by the invention, the restoring force of the variable-diameter bundle piece is superposed on the torsion spring waisted part, so that the rebound effect is improved, the service time and frequency of high-stability electric connection are prolonged, and the service life is remarkably prolonged.
本发明公开了一种分体式扭簧插孔包括孔套、扭簧、变径束件和顶盖,孔套一端内壁设有环形台,扭簧为圆筒结构,扭簧中部设有内凹的收腰部,扭簧插入孔套内部,扭簧一端顶触环形台,变径束件紧密套设于收腰部外部,孔套内壁与变径束件之间留有间隙,顶盖为中空结构,顶盖盖设于孔套另一端上,顶盖顶触扭簧另一端。本发明提供的一种分体式扭簧插孔,通过变径束件自身的恢复力叠加到扭簧收腰部上,提升回弹效果,延长其高稳定电连接的使用时长和次数,显著提升使用寿命。
