Abstract: A ratchet wrench with a direction switching structure includes a wrench body with an axial slot, a control slot, and a pivot slot which are interconnected, and a ratchet wheel, a ratcheting member, and a switching member are installed therein, respectively. The switching member pushes against the ratcheting member through a prop member and selectively controls the engagement between the ratcheting member and the ratchet wheel. The circumferential wall of the pivot slot has a circular slot and a stepped surface formed at a position near an opening of the pivot slot provided for latching the switching member into the circular slot by a latch portion thereon and being stopped by the stepped surface for the positioning purpose. The prop member pushes against an appropriate position of the ratcheting member to prevent an unsecured engagement between the ratcheting member and the ratchet wheel.

Abstract: A wire stripper detects contact between a core wire of an electric wire and stripping blades and detects if the electric wire is cut short. The wire stripper includes a signal analyzer circuit that measures an impedance through the stripping blades for a change in the impedance caused by contact with the wire core and a buffer circuit, that when a contact of the stripping blades with the wire core is detected, applies a signal having the same level as that of an electric signal applied to the stripping blades to a side of a shielding material of a shielded cable for transmitting the electric signal to and from the stripping blades so as to reduce or prevent current leakage between a signal line of the shielded cable and the shielding material.

Abstract: A telescopic handle for a hand tool includes a main shank connected to a tool head at a distal end and insertable into an outer sleeve which a user grips. The main shank has a plurality of axially spaced retained regions such that a radially movable retaining member is engageable with a selected one of the retained regions. A key-and-keyway mechanism is disposed to guide axial movement of the outer sleeve and to guard against rotation of the outer sleeve relative to the main shank so as to permit delivery of an appropriate torque to the main shank. An operating member is disposed on and movable axially relative to the outer sleeve to radially move the retaining member.
