Hand-held tool allows users to comfortably transfer the tool from a palm grip to a pen grip to maintain the use of the fingers and the thumb when the hand tool is stored in the palm. Several storage housings are attached offset from a drive shaft housing for improved torque transfer from a hand to the tool head, integral storage of work pieces, optimized use of palm torque during use, and better overall grasping. Also equipped with a retractable or non-retractable torque drive shaft designed to allow the fingers and thumb to be rotated freely when the tool is in palm grip and capable of transmitting torque through the housing when an axial pressure force Is placed along the drive shaft to engage the tool head with the housing. The drive shaft can also be reversed to create a prolongation shaft or placed in another opening of the housing.

An angle adjustable hand tool includes a driving head (40) pivotably connected to a handle (10) and a pawl (20) is received in the handle and removably engaged with the teeth (43) in the driving head. A button (30) is engaged with a hole (115) in the handle and perpendicularly communicates with the hole (114) in which the pawl is received. The button includes a recess (32) and a second contact surface (33) connects the recess. When the button is pushed, the pawl is located in the recess of the button so that the driving head can be pivoted relative to the handle. The driving head is set when the pawl is engaged with the teeth of the driving head.

A hand tool (10) having an adjustable head (20) comprises a head (20), a handle (30), a fastening device (24) and a joint lock mechanism, characterised in that: a bottom side of a concave pivotal portion (31) of the handle (30) has an inclining surface inclining forwardly from a first side of the concave pivotal portion (31) to a second side of the concave pivotal portion (31); the joint lock mechanism comprises: a first engaging device and a second engaging device; the second engaging device comprises a pull button (41) and a biasing device (42). The pull button (41) is moveable from an unlocked position at the first side of the concave pivotal portion (31) to a locked position at the second side of the concave pivotal portion (31). The biasing device is disposed at a front end such that when the pull button (41) is at an unlocked position, a gap (344) is formed between a rear end of the pull button (41) and the bottom side of the concave pivot portion (31), when the pull button (41) is at a locked position, a front end of the pull button (41) is adapted to engage the first engaging device.

This invention provides an articulated wrench, comprising: a box end; a handle; a fastening device passing through the through holes of the box end and handle; and a flexed spring disc. The fastening device has a head and a shank, wherein the head gradually expands outwards from the shank to form a flared angle having a tapering angle less than 45°. The flexed spring disc is provided in the indent of the box end and flexed along a diameter thereof to form a curvature.

A ratchet wrench (10) includes a ratchet head (12) having a part-cylindrical surface (18) with head teeth (20) thereon and an elongated handle (14) hingedly coupled to the head (12). The handle (14) has an axial first bore (32). A rod (46) is disposed in and movable within the first bore (32) between an engaged condition for locking the head (12) in a selected position and non-engaged condition for relative movement between the head (12) and the handle (14). A biasing structure (56) biasses the rod (46) to the engaged condition. A retaining structure (58) is coupled to the rod (46) for retaining the rod in its non-engaged condition.
