The ratchet wrench comprises a functional head (1) and a handle (2) hingedly connected to each other, a ratchet toothed wheel (4) rigidly attached to the functional head (1), a movable ratchet pawl (5) installed on the handle (2), a working spring (6) that biases the ratchet pawl (5) against the ratchet wheel (4), a movable releasing member (7) installed on the handle (2) and manually operable to move the ratchet pawl (5) to a position out of engagement with the ratchet wheel (4), and a movable locking element (69) installed on the handle (2) and manually operable between a rest position, in which it does not interfere with the ratchet pawl (5), and a locking position, in which it comes into contact with the ratchet pawl (5) holding it in said engaged position with the ratchet wheel (4).

A wrench adjustable in head angle includes a pull lever having one end provided with an accommodating groove for receiving a spring and a resisting pin. The resisting pin is fitted thereon with a push member, and the pull lever is pivotally connected with a driving head. The resisting pin has one end elastically pushed by the spring to be engaged with one end of the driving head and the resisting pin is engaged with the push member. The push member can be pushed to actuate the resisting pin to press the spring, letting the resisting pin disengaged from the driving head for adjusting the angle of the driving head, convenient in operation.

Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a first endplate, a second endplate, and a moving mechanism that is operably coupled to the first and second endplates. The moving mechanism may include a wedge, a first sliding frame and a second sliding frame disposed on opposite sides of the wedge, a screw guide housing a rotatable first set screw and a rotatable second set screw opposite the first set screw. The first set screw may be operably coupled to the second sliding frame and the second set screw may be operably coupled to the wedge. The moving mechanism may operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws and operably adjust an angle of inclination between the first and second endplates upon translating the first set screw or second set screw.

A hand tool includes a first body, a locking member and a second body. The first body has a function end, a pivotal hole, a first toothed portion, a first groove, a second groove and a first restriction groove. The locking member has a second toothed portion, a second restriction groove, a first connection portion, a restriction member, an engaging member and a resilient member. The second body has a third connection portion connected to the first connection portion to connect the first and second bodies. When the locking member moves to a first position, the engaging member is engaged with the first groove. The first toothed portion is engaged with the second toothed portion. When the locking member moves to a second position, the engaging member is engaged with the second groove. The first toothed portion is disengaged from the second toothed portion.

An adjustable tool handle for holding a tool during use provides an improved handling of tools during use of tools that are difficult to use on their own, specifically L-shaped hexagonal wrenches. The adjustable tool handle includes a tool handle body with a handle and an adjustable opening for receiving a tool. In order to place a tool within the tool handle, a user opens the tool handle. When the tool handle is open, one leg of the tool handle is inserted into one of a plurality of openings on the back of the body and the other leg is placed within the adjustable opening. After the tool is placed within the tool handle, the tool is held in place by a securing mechanism. With the tool coupled to the tool handle, a user is able to tighten and loosen work pieces of different sizes and different types.

A hand tool includes a handle, a press member, a shank body and multiple latch assemblies. The handle is formed with a receiving cavity and a locating hole in communication with the receiving cavity. The press member is movably disposed in the locating hole. The shank body is fitted in the receiving cavity and movable relative to the handle. The shank body is formed with multiple sockets. The latch assemblies are respectively mounted in the sockets. When the shank body is moved, (for example, slid or rotated) relative to the handle to make one of the sockets aligned with the locating hole, the latch assembly latches the shank body with the handle. When pressing the press member, the latch assembly unlatches the shank body from the handle, the shank body is movable relative to the handle.

A hand tool handle includes a main body, first and second installation holes, and a detachable tool holder. The main body has a side wall portion and first and second edge portions. The first installation hole is provided at the side wall portion, and the second installation hole is provided at the first edge portion. The first and second installation holes are provided with adjacent locating detents. The detachable tool holder has a latching portion and a tool insertion hole. The latching portion of the detachable tool holder is configured to be inserted and held in the first installation hole or the second installation hole, and the tool insertion hole is configured to receive an external tool. The main body may have substantially a shape of cylinder or faceted polygon cylinder.

An angle adjustable wrench includes a handle, a main part, an adjustment unit and a jaw unit. The handle includes a head which has inner teeth defined in the inner periphery thereof. The head is installed in the main part. The adjustment unit includes a sleeve with an axial hole, two pawls, a resilient member and a button. The button includes a first neck and a second neck. The resilient member pushes the button, and the two pawls are pushed by the first neck and engaged with the inner teeth of the head. The jaw unit includes a movable jaw, a rotary wheel and a fixed jaw. The rotary wheel is threadedly mounted to the shaft. The main part together with the jaw unit are pivoted an angle relative to the handle by pushing the button.
