A multi-tool includes a cylindrical body and a head extended from an end of the cylindrical body, the head to be pivoted between a first position with the head aligned with the cylindrical body and a second position with the head oriented at an angle to the cylindrical body, the head including a cradle to support a segment of a roller chain.

The invention relates to a detacher for chain quick link comprising: a main body with a first end and a second end, the main body has a fixed jaw; a driving member with a screw portion screwed into a screw hole provided at the first end of the main body, when the driving member is rotated, the driving member is capable of displacing toward the second end of the main body; and a sliding member displaceably installed in the main body, a movable jaw of the sliding member corresponds to the fixed jaw; when the driving member displaces toward the second end of the main body, the sliding member is driven to displace toward the second end of the main body together, so that the movable jaw moves toward the fixed jaw for disassembling a quick-linked chain.

A wedge driver and method therefor is presented. A wedge driver can be operably coupled to different ends of a link joiner to drive a wedge therebetween to form a single link. The wedge driver can also drive the wedge out of the link joiner. The present disclosure provides the benefit of allowing the safe and effective removal of the link joiner by preventing violent or forceful decoupling of a link joiner. The wedge driver can include a trunk, a first prong, a second prong, a bolt, and a driver. The driver can be spring enabled, such that the driver can recede into the trunk as the bolt egresses the trunk. A bolt of the wedge driver can push a driver out of the trunk to axially drive the wedge into (or out of) a link joiner without rotating the wedge.

A ratchet wrench including a bicycle toolset combined therewith includes a main body having a first end including a ratchet drive head and a second end including an accommodating cavity. A toolset in a combination configuration is detachably connected to the main body and includes a length disposed in the accommodating cavity. The toolset comprises at least one bicycle tool.

A multi-tool includes a pair of plates having respective handle portions, joint portions, and head portions, with the plates pivotally connected to each other at the joint portions, and to be pivoted relative to each other to establish an open position and a closed position of the plates. A bit holder is extended from an end of one of the plates, with the bit holder including a socket to receive an insert bit, the handle portion of the one of the plates including a storage area to receive and store the insert bit, and, in the closed position of the plates, the plates to overlap each other with the handle portion of the other of the plates to cover the storage area and the handle portion of the one of the plates.

A hand tool for assembling and disassembling a work piece. The hand tool can be configured for assembling and disassembling a work piece having a plurality of linkable units. The hand tool can include a first work station where at least one assembling operation can be performed and a second work station where at least one disassembling operation can be performed.
