摘要： A hand tool assembly includes a rod and a handle which is pivotably connected to the rod, and a control unit which is movable along the rod. When the rod and the handle are located linearly, the control unit is moved to a position where the rod and the handle are secured linearly. When the handle is perpendicular to the rod, the control unit is moved another position where the handle is secured perpendicularly to the rod. The rod and the handle are able to be connected with different hand tools.

摘要： A hand tool includes a shank, a sleeve, a control member, a pressing member, an end piece and a resilient member. The shank has multiple annular grooves. The control member and the resilient member are located in the chamber of the sleeve and the end piece closes the sleeve. The shank extends through the control member and the end piece. When the pressing member is not applied by a force, the sleeve can only rotate relative to the shank and cannot move relative to the shank. When the sleeve is applied by a force, the sleeve can move relative to the shank.

摘要： An improved cutter knife and particularly to a cutter knife allowing positive and inverse gripping when in use consists of an upper shell and a lower shell that are coupled to form a body. The body has one end forming a handgrip conforming to ergonomics to allow positive and inverse gripping. The handgrip has a blade anchor section and a blade fast change section on one end to allow positive or inverse gripping and fast replacement of the blade. The positive gripping may be used for ordinary cutting such as for paper or cloths. The inverse gripping may be used for heavy duty cutting with a greater force such as for cardboard or wooden laminates. Thus it provide dual functions and may be used conveniently to overcome the limitation of conventional cutter knives that allow only positive gripping.
摘要翻译： 一种改进的切割刀，特别是一种在使用时允许正向和反向夹持的切割刀包括联接以形成主体的上壳体和下壳体。 身体的一端形成符合人体工程学的手柄，以允许正向和反向夹紧。 手柄在一端具有刀片锚固部分和刀片快速变化部分，以允许正向或反向夹紧并快速更换刀片。 正向夹持可用于普通切割，例如用于纸或布。 反向夹紧可用于较大力量的重型切割，例如纸板或木质层压板。 因此，它提供双重功能，并且可以方便地使用以克服仅允许正向夹持的常规刀具的限制。

摘要： A ratchet wrench includes a tubular body, a ratchet unit, a driving head, a control unit and a connection unit. The ratchet unit is operated in either rotation mode or spinning mode. The control unit controls the ratchet unit to rotate clockwise or counter clockwise. The connection unit is connected with a tool. When the body is rotated, the ratchet unit drives the driving head to rotate an object connected to the driving head. When the tool is span relative to the body, the ratchet unit also drives the driving head to rotate an object.

摘要： A magnetic retainer includes a body, a magnetic member, a plate and a light unit. The body has a space for receiving objects and the magnetic member is connected to the bottom of the body to attract the objects. The plate has a concaved portion for receiving the objects and is rotatably connected to the body. When the light unit is rotated to a first position relative to the plate, the light emitting member faces outside of the plate. When the light unit is rotated to a second position relative to the plate, the light emitting member faces the concaved portion of the plate.

摘要： A pair of pliers includes two parts pivotably connected to each other. The two parts respectively have jaws located correspondingly. A control member has one end pivotably connected to one part and an operation rod is pivotably connected to the other part and has one end movably inserted into the control member. A control lever has a first hole through which the operation rod extends. The operation rod has a first engaging portion which is engaged with a second engaging portion of the control lever. A resilient member is in contact with the control lever to engage the second engaging portion with the first engaging portion to set a desired angle between the two parts.
