Abstract: A pipe disassembling tool includes a first arm and a second arm pivotally connected with each other by a pin. The first arm and the second arm respectively have a first connecting portion and a second connecting portion formed on a first end of each of the first arm and the second arm. A torsion spring is sleeved on the pin and has two opposite ends respectively abutting against the first arm and the second arm to make the first arm and the second arm abut each other when the tool is in an original condition. A first disassembling portion is formed on a second end of the first arm and a second disassembling portion is formed on a second end of the second arm for user to detach the pipe.

Abstract: An adjustable wrench for vehicle service includes a main shaft, a actuated shaft pivotally connected to the main shaft and a controlling unit pivotally mounted on the main shaft for selectively braking the actuated shaft. The main shaft includes a first end having a grip sleeved thereon and a second end having a first hook formed thereon and a first stub extending therefrom. The actuated shaft includes a first end pivotally mounted on the main shaft, and a second end having a second hook formed thereon and a second stub extending therefrom. The first and second hooks are provided to engaged to two stubs extending from a workpiece for detaching/mounting the workpiece. The first and second stubs are inserted into two holes in the workpiece for detaching/mounting the workpiece. The controlling unit controls an angle between the main shaft and the actuated shaft.

Abstract: This invention relates to a kind of spanner with an improved handle, comprising a spanner body, a lengthening bar and a positioning set, wherein the lengthening bar is set on one end of the spanner body, and the positioning set is between the spanner body and the lengthening bar. The spanner is used as a common spanner or lengthened for operations in special occasions, and the scope of application is enlarged. The positioning set is used to position the spanner body and the lengthening bar accurately, and the spanner is easy to handle and store.

Abstract: The invention provides an improved structure of a piercing drain device used on a sealed chamber mainly comprising a first component, a second component, a piercing component, a first arc pad and a second arc pad. Because the first component and the second component are pivoted on their end portion, increasing the force arm, the force of clamping is then increased to improve the gastight. Without any pad or only with the first arc pad or with both the first and the second arc pad, the improved structure is used on three different sizes sealed chamber, and has wide range utilization.

Abstract: A two-way manually operated pump structure consisting of a pump body, a nozzle mount, a control ring mount, and other structural components that are assembled together, in which rotating the control ring mount shifts the air direction between them and thereby enables manual inflation and deflation operation.

Abstract: An improved structure pliers for inner and outer diameter C-shaped snap rings comprised of a two-part symmetrically paired left and right-handled pliers body that is situated together at a predetermined point between its two inner sides and, furthermore, in an upper and lower overlaid and pivotably linked assembly positioning; two implement ends capable of being articulated apart and together by pivoting at the front portion and two hand grips for manual operation disposed at the rear portion; and an elastic component mounted between the two hand grips near their pivotable linkage area to provide a rebound force when the two hand grips are pivoted by squeezing. The two implement ends have a first mounting hole and a second mounting hole respectively formed in them and the two hand grips have a third mounting hole and a fourth mounting hole respectively formed in them near their pivotable linkage area.

Abstract: The present invention discloses a wrench having an opening that fits different sizes of screwing and unscrewing objects such as bolts and nuts, and such wrench comprises a main body having a first clipping member and a second clipping member along the axis of the main body and being disposed on at least one of its ends, the first and second clipping members enclose an opening, and the lateral sides of the enclosed opening is for clipping and driving the external diameter of the bolts or nuts characterized in that the length of the front end of the first clipping member is longer than the that of the second clipping member, and a first blocking recession showing a pair of symmetric obtuse angles is disposed at the lateral side adjacent to the opening.

Abstract: The present invention discloses an oil filter wrench comprising a wrench body having an axial hollow space at the center of a surface along one end of its axis, and each of the both surfaces of the axial hollow space has a sliding groove parallel to each other, and a driving device being disposed at the center of the surface along the other end of the axis for the mounting of a cylindrical driver; a pair of clipping members being pivotally coupled to two sliding grooves of the wrench body by means of sliding displacement, and its thickness corresponds with the parallel position and has serrations on them.

Abstract: A sand cloth packaging structure for vacuum-type rotary sanders comprised of sand cloths having a number of vacuum holes that are cluster mounted on the circular surface, with a number of support ribs that protrude upward from the bottom surface of the circular surface and, furthermore, are aligned within the circumference of the bottom surface. A surrounding annular wall extends along the outer diameter of the circumference and there are internal splines along the interior side of the annular wall that constitute a union opening which is congruous with the circumference of the bottom end. Positioned along the top surface of the said circular surface are a number of vertical guide posts that are in alignment with the vacuum holes of the said sand cloths and which are provided for insertion into the vacuum holes of the sand cloths.
