Abstract: A ratchet screwdriver includes a drive shaft inserted into a shaft-receiving space of a shaft-mounting seat, a regulator sleeved rotatably around one end of the shaft-mounting seat to selectively push two pawls that are mounted in the shaft-receiving space, and a handle fixed on the shaft-mounting seat. The pawls selectively engage a ratchet wheel fixed on the drive shaft when the regulator is moved to first and second angular positions relative to the shaft-mounting seat.

Abstract: A swingable handle is adapted to deliver torque for rotating a tool bit of a hand tool, and includes front and rear handle bodies pivoted to each other. A first mating wall of the front handle body mates with and is turnable relative to a second mating wall of a spring-biased coupling member which is movable longitudinally relative to the rear handle body. A retaining member is disposed between the first and second mating walls to restrain the first mating wall from rotation relative to the second mating wall. The coupling member has a shifted portion with a relatively large actuating wall surface so as to be conveniently actuated to move the second mating wall away from the first mating wall.

Abstract: A nail locating device is adapted for locating a magnetically attractive nail that was driven into a non-magnetically attractive board, and includes a seat, an indicator rod and a biasing spring. The seat is adapted to be moved on a surface of the board, and confines a vertically extending receiving space therein. The indicator rod is disposed in the receiving space, and has a ball portion and a magnet supporting portion that extends downwardly from the ball portion. The magnet supporting portion has a magnet member mounted thereto. The biasing spring is disposed in the receiving space, and supports the ball portion of the indicator rod in the receiving space such that the indicator rod is pivotable in the seat and is movable downwardly in the receiving space due to attraction of the magnet member to the nail in order to indicate the location of the nail in the board.

The ratchet mechanism is mounted in the front chamber, and is connected operably to the connecting end such that the ratchet mechanism is operable to permit the handle to drive rotation of the drive shaft in at least one direction.

Abstract: A screwdriver-type tool includes a handle having first and second handle parts connected pivotally to each other. An inclination positioning unit is provided such that the first and second handle parts are rotatable between an alignment position, where the first and second handle parts are aligned with each other, and an inclined position, where the first and second handle parts form an obtuse angle therebetween.

Abstract: A ratchet assembly includes a housing having an actuator confining portion which extends axially and projects radially, which confines an actuator receiving space for receiving an actuator, and which is formed with an axially extending slot. A ratchet body is disposed rotatably in the housing, and has an outer surface provided with first and second ratchet wheels which are axially displaced from each other so as to define a slide portion therebetween. The actuator includes a curved plate, and first and second pawl members which project radially from the curved plate toward the ratchet body and which are disposed on opposite sides of a central line that extends through a central point of an arc length of the curved plate.

Abstract: A driving tool includes a handle having a tubular surrounding wall defining a torch receiving compartment. A front end wall is disposed at a front end of the surrounding wall, and has a drive shaft extending outwardly of the torch receiving compartment. The front end wall is formed with a lamp receiving hole offset from the drive shaft and in communication with the compartment. A torch is received removably in the torch receiving compartment, and includes a tubular torch housing with front and rear end portions. The front end portion confines a battery receiving space to receive a battery cell therein. A switch member is mounted in the rear end portion of the torch housing, and has a first switch contact to establish electrical contact with a first battery terminal of the battery cell.

Abstract: A ratchet spanner includes a spanner body with a head portion confined by a peripheral wall. Top and bottom flanges extend inwardly and radially from top and bottom ends of the wall. The top flange has a curved inner peripheral surface with an open-ended slot. The bottom flange defines a bottom opening, and has a circular inner peripheral surface formed with an inward flange that extends radially and inwardly into the bottom opening. A stepped insert member is inserted into the head portion, and has a curved shoulder between upper and lower portions thereof. The upper portion of the insert member is formed with an open-ended slot. The curved shoulder abuts against the top flange of the head portion for preventing upward removal therefrom. A ratchet wheel is rotatably disposed in the head portion, and has an upper annular groove and a lower circular shoulder abutting against the inward flange of the head portion for preventing downward removal therefrom.

Abstract: A ratchet screwdriver includes a handle defining a ratchet shaft receiving hole therethrough, and a ratchet shaft disposed therein. The ratchet shaft has a ratchet wheel mounted securely between first and second end portions, and an engaging unit between the ratchet shaft and a drive shaft inserted in the first or second end portions to prevent axial displacement and permit co-rotation thereof. A ratchet housing includes a coupling portion sleeved on the ratchet shaft and coupled to the handle for co-rotation therewith, a wheel confining portion defining a cavity enclosing the ratchet wheel, and a shoulder between the coupling and wheel confining portions. The wheel confining portion is formed with a pawl retaining groove in communication with the cavity to receive a pawl member which is mounted pivotally on the shoulder and which extends radially into the cavity.

Abstract: A hand operated tool includes a tubular casing having an end wall formed with a through hole offset from an axis thereof, and a circumferential wall that extends coaxially from the end wall to form an open end and that confines a receiving space. A mounting axle extends coaxially from the end wall into the receiving space. A cover member is mounted on the circumferential wall and is movable relative thereto between a first position, where the cover member covers the open end, and a second position, where the cover member uncovers the open end. A rod retention tube extends from the cover member outwardly of the receiving space, and is aligned with the through hole in the end wall and is in communication with the receiving space when the cover member is at the first position. A rotary bit retaining member is inserted removably into the receiving space when the cover member is at the second position.

Abstract: A driving tool includes an elongate hollow handle formed with a longitudinally extending receiving chamber and an open rear end, a tubular shank mounted securely on a front end of the handle and confining an axial bore communicated with the receiving chamber, a telescopic retriever disposed in the receiving chamber, a rear cap mounted removably on the rear end of the handle, and a spring-loaded retaining unit mounted on the shank. The axial bore has a cross-section smaller than that of the receiving chamber. The shank has an open drive end adapted for receiving removably a tool bit. The telescopic retriever has a front end extendible into the axial bore to reach the drive and, and provided with a magnet member. The front end of the telescopic retriever is extendible forwardly to project from the drive end. The retaining unit is extendible radially into the axial bore so as to be adapted to retain removably the tool bit at the drive end.

Abstract: A nail locating device includes a seat, a coupling member and an indicating rod.
