Abstract: A tool-displaying apparatus includes a base, a tray and at least one linkage. The tray is connected to the base so that the tray can be pivoted relative to the base between a flat position and a fully pivoted position. The linkage is used to keep the tray in the fully pivoted position relative to the base.

Abstract: Disclosed is a method for marking a socket. The method includes the steps of providing a socket, making at least one indented mark in the surface of the socket, executing a heat treatment on the surface of the socket, providing at least one colored layer in the indented mark, providing an electroplated layer on the surface of the socket except the colored layer, removing a portion of the electroplated layer from the surface of the socket to form an exposed portion of the surface of the socket, and providing a black-dyed layer on the exposed portion of the surface of the socket. The heat treatment can be executed after the colored layer is provided.

Abstract: A wrench includes a handle, a yoke, a shaft, a head, a mandrel, a first transmitting unit and a second transmitting unit. The shaft includes a first section securely connected to the handle and a second section rotationally inserted in the yoke. The head is pivotally connected to the yoke. The mandrel is inserted through the head. The first transmitting unit can be used to transmit a small torque to the mandrel from the handle spun relative to the yoke. The second transmitting unit can be used together with the first transmitting unit to transmit a large torque to the mandrel from the handle pivoted together with the yoke.

Abstract: A one-way wrench includes a head, a wheel, a pawl, a spring-biased detent assembly, a handle, a grip, a shaft and a transmission unit. The wheel includes a rack extending thereon. The pawl is for engagement with the wheel. The spring-biased detent assembly pushes the pawl against the wheel. The handle is connected to the head. The grip is rotationally located on the handle. The shaft is rotationally inserted through the handle and includes a first end fit in the grip and a second end located outside the handle. The transmission unit includes a first gear connected to the second end of the shaft, a second gear engaged with the first gear, a third gear engaged with the second gear, and a fourth gear connected to the third gear on one hand and engaged with the rack of the wheel on the other hand.

Abstract: A method is disclosed for marking a socket. The method includes the steps of providing a socket, pressing the socket to make an indented mark, executing thermal treatment on the socket, coloring a portion of the socket near the indented mark to form a printed layer, vibrating and grinding the socket to remove the printed layer from the socket except the indented mark, and electroplating the socket to form a coating on an external side and an internal side of the socket.

Abstract: A storing apparatus includes an attaching portion, a handle and at least one storing portion. The attaching portion is used for attaching the storage apparatus to a drawer of a tool cart. The handle is operable for moving the drawer. The storing portion is used for storing small stuff such as screws and nuts.

Abstract: A socket apparatus includes a socket, at least one detent and an elastic element. The socket includes a bit-receiving recess in an end, a mandrel-receiving recess in an opposite end, at least one vent in communication with the mandrel-receiving recess and at least one aperture in communication with the mandrel-receiving recess. The detent is inserted in the aperture so that the detent includes a portion disposed in the mandrel-receiving recess. The elastic element is used to bias and keep the detent in the aperture.

Abstract: A method is disclosed for marking a socket. The method includes the steps of providing a socket, pressing the socket to make an indented mark, executing thermal treatment on the socket, coloring a portion of the socket near the indented mark to form a printed layer, vibrating and grinding the socket to remove the printed layer from the socket except the indented mark, and electroplating the socket to form a coating on an external side and an internal side of the socket.

Abstract: A wrench includes a handle and at least one head extending from an end of the handle. The head includes a driving portion formed thereon, a retreating portion formed near the driving portion and a mouth defined near the retreating portion. The driving portion of the head includes two parallel facets separated from each other by a gap. The retreating portion of the head is formed with two arched facets as two arcs of a circle with a diameter. The mouth is made with a width. The width is smaller than the gap that is smaller than the diameter.

Abstract: A shell with printing patterns has a shell body, a printing layer and an electroplating layer. The shell body has an outer surface and an area. The printing layer is attached to the outer surface of the shell body to form the printing patterns and has an area smaller than that of the shell body. The electroplating layer is attached to the outer surface of the shell body at a region beside the printing layer.

Abstract: A metal shell with printing patterns has a metal body, a printing layer and an electroplating layer. The metal body has an outer surface and an area. The printing layer is attached to the outer surface of the metal body to form the printing patterns and has an area smaller than that of the metal body. The electroplating layer is attached to the outer surface of the metal body at a region beside the printing layer.

Abstract: A plastic shell with printing patterns has a plastic body, a printing layer and a plating layer. The plastic body has an outer surface and an area. The printing layer is attached to the outer surface of the plastic body to form the printing patterns and has an area smaller than that of the plastic body. The plating layer is attached to the outer surface of the plastic body at a region beside the printing layer.

Abstract: A tool rack includes a rack and a plurality of blocks disposed to the rack, the rack having a T-shaped slot defined longitudinally in a front surface thereof and a bottom surface defining the T-shaped slot, a plurality of notches defined in the bottom surface for engagement with the blocks and each of the notches defined by an inclined surface extending toward the bottom surface and a horizontal bottom, the block including a front part and a rear part which is T-shaped for engagement with the T-shaped slot and has a triangular protrusion extending from a distal end thereof for engagement with the notch, the front part having an engaging device disposed to a distal end thereof for engagement with a tool.
