A pipecutter includes a housing, a motor, a rotating assembly, and a first drive assembly. The rotating assembly includes a first bracket assembly, a second bracket assembly, and a locking assembly, where the locking assembly is configured to lock or unlock a pipe and the pipecutter. The first drive assembly is driven by the motor to drive the rotating assembly to rotate. The locking assembly includes a rocker arm; when the rocker arm is at a first position, the locking assembly is in an unlocking state; and when the rocker arm is at a second position, the locking assembly is in a locking state. The pipecutter further includes a second drive assembly, the second drive assembly includes a first pushing member which is able to push the rocker arm to move from the first position to the second position.

An apparatus for machining a tubular piece, wherein the apparatus includes a frame element, support rollers, which are associated with the frame element, support a workpiece and rotate the same around its longitudinal axis. In addition, the frame element is provided with a machining unit adapted to be movable towards and away from the workpiece. The machining unit includes a tool member, such as for example a cutting tool, as well as support wheels adapted to bear against a workpiece. The machining unit is arranged to link up with the frame element through the use of an auxiliary frame element adapted to clamp itself thereto at not less than two support points, for example through the use of a self wedging assembly implemented with an indentation.

A device for cutting the foil on a bottle, including a circular shaped body that has a top end and a lower end, wherein the body includes a lip at the top end that protrudes inward such that it can rest on top of the mouth of a bottle, and a plurality of cutting elements attached to the lower end of the body on the inside, such that when the outside of the body is pressed by the hand of a user the cutting elements make contact with foil wrapped around the top end of a bottle, and where the distance from the top end of the body to the lower end is sufficent to enable the cutting elements to make contact with the foil below the bead of the bottle.

A hand tool for cutting tubular workpieces such as copper tubing used for plumbing includes a rotary cutting head which has a slot for receiving a length of tubing to be cut, a gear drive mechanism for rotating the cutting head, and a clamping handle which supports the gear drive mechanism, which is rotatably driven by a battery powered electric motor. to thus rotate the cutting head to sever a length of tubing. The clamping handle includes a pair of longitudinally disposed, generally semi-cylindrically-shaped handle shells which are pivotable apart from one another to receive a length of tubing to be cut, and pivotable to a closed position and compressed in the palm of a workman's hand to press against and clamp the tool to a length of tubing being cut.

A tube cutter comprises a main body, a cutting member and a base. The main body has a cutting space and a mounting portion corresponded to the cutting space. The cutting member, which is received in the main body, has a at least a portion protruding into the cutting space. The base has a first clamping portion and a second clamping portion; wherein the base is received in the mounting portion of the main body and can be switched between a first angle and a second angle. The first clamping portion is communicated with the cutting space to clamp a tube with a first predetermined diameter when the base is switched to the first angle. The second clamping portion is communicated with the cutting space to clamp a tube with a second predetermined diameter when the base is switched to the second angle.

A tube cutter comprises a main body, a cutting member, a base and a restricting member. The main body has a cutting space and a groove. The groove includes a top opening and two side openings. The cutting member is received in the main body, having a least a portion protruding into the cutting space. The base is detachably received in the groove of the main body and switched between a first angle and a second angle. The restricting member is movably received in the main body and adjacent to one of the side openings to be turned between a first position and a second position. At least a portion of the restricting member blocks the side opening when the restricting member is turned to the first position; the restricting member leaves the side opening when the restricting member is turned to the second position.
