An attachment assembly for being connected with a hand tool includes an active unit, a passive unit and a switching shaft. The active unit includes a front wheel, a middle wheel and a rear wheel are simultaneously rotatably connected in sequence. The passive unit includes a first wheel and a second wheel are simultaneously rotatably connected. The switching shaft pivotably connects the active unit and the passive unit, and switches the active unit and the passive unit being rotatable or not.

A high strength wrench includes a head portion, a shaft and a handle. A length of the shaft is multiple times of a length of the handle. At least one slot extends along a longitudinal direction of the shaft and is formed at a circumferential surface of the shaft. A cross section shape of the shaft has a structural profile of an outer side with a relatively greater thickness and an inner portion of a relatively smaller thickness. Accordingly, the shaft has a greater structural strength to allow the wrench to bear operations of high torque.

A multi-tool assembly includes a grip and a receiver that is extendable through the grip. The receiver has a first half pivotally coupled to a second half thereby facilitating the receiver to be bent into a plurality of angles. A plurality of bits is provided and each of the bits is insertable into a respective one of the first wells or the second wells for storage. Each of the bits is positionable into the receiver to tighten or loosen a fastener. A ratchet is integrated into the grip and the ratchet engages the receiver when the receiver is extended through the grip. The ratchet facilitates the grip to ratchet around the receiver in either a first direction or a second direction. In this way the grip can be rotated back and forth around the receiver for tightening or loosening the fastener.

A wrench is provided, including: a rod member; and a driving member, rotatably connected to the rod member, including an insertion hole disposed therethrough, the insertion hole being configured for a connector to be replaceably inserted therewithin.

A wrench includes a function end having an extension portion extending therefrom. Two arms extend from the function end and toward a direction opposite to the extension portion. A space is formed between the two arms and the extension portion. An engaging portion is formed to the distal end of the extension portion for receiving a hand tool. A rotary head is pivotably located in the space of the function end by two bolts respectively extending through the two arms and connected to the rotary head. The rotary head includes an outer part and a control unit which is located in a through hole defined through the outer ring. The control unit includes a control part and a driving part respectively located on two opposite end of the rotary head. The control part is rotated to control the direction that the driving part rotates.

An angle drive socket tool that provides interchangeable multi-angular socket for inserting a tool. A drive shaft has a driver engagement end and a magnetic enabled concave fastener receiving end with retainment and drive engagement pins. A driver component having a spherical insert end with a drive pin engagement channel extending there about an oppositely disposed drive configured input end, such as a hex socket suitable to drive a fastener of choice as illustrated in the preferred embodiment.

The present invention provides a pneumatic hand tool with adjustable operating angle, comprising a grip body and a tool head body interconnected with each other. The grip body has a grip flow channel, and said tool head body has a tool head flow channel. The grip body and said tool head body are interconnected through two rotary joint faces to form a joint portion capable of adjustment of the operating angle. The two rotary joint faces respectively have connecting areas for uniform circumferential motion and high pressure air ports configured along the rotation center. And the two rotary joint faces are inclined to facilitate adjustment of the operating angle of said tool head, and to ensure good air tightness of the high pressure air ports inside the joint portion.

A hand tool for providing a hand tool for providing a multiple angle adjusting wrench according to the present invention. The wrench includes the three segments: an open wrench segment, a center section segment, and a closed wrench segment. It also includes two pivot points where the wrench segments are coupled to the center section segment. A gear-spring combination is used to lock the segments into a desired orientation while permitting easy reconfiguration of the wrench.

A multi-section universal tool includes an assembling member, a connecting member, a working member and two elastic members. The assembling member has an assembling portion and a first receiving room. The connecting member includes a connecting ball joint and a second receiving room. The connecting ball joint includes a connecting elastic abutting member which has a tendency to radially move outwardly. The connecting ball joint is inserted into the first receiving room and movable relative to the first receiving room to be in a first connecting position or a second connecting position. The working member includes a working ball joint including a working elastic abutting member which has a tendency to radially move outwardly. The working ball joint is inserted into the second receiving room and movable relative to the second receiving room to be in a first working position or a second working position.

A support rod for a hollow, flexible torque transmitting shaft for treating a bone includes support and flex portions. When the rod is received at a desired position within the shaft, the support portion extends through a first non-bendable portion of the shaft. An outer diameter of the support portion substantially corresponds to an inner diameter of the shaft to support the first portion. When the support rod is received at the desired position, the flex portion extends through a second bendable portion of the shaft. The flex portion includes a holding portion having an outer diameter substantially corresponding to an inner diameter of the second portion and a gap portion having an outer diameter reduced relative to the outer diameter of the holding portion to form an annular gap between the gap portion and an inner surface of the holding portion.
