摘要： 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.

摘要： 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.

摘要： 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. The two-part pliers body has a jaw at each of its two upper and lower two sides that are overlaid and in a pivotably linked assembly positioning and, furthermore, which respectively share the same pivotal axis. The two jaws have a through-hole disposed that corresponds to the site of the first mounting hole and second mounting hole, respectively, and attached to its front end are tip members capable of being turned up and down for angular adjustment to facilitate C-type snap ring distension or constriction. Positioned at each of the upper and lower two sides of the two jaws in a movable arrangement and, furthermore, respectively along the same axis is a direction control component. Each direction control component has projecting from it a long post and a short post that are respectively inserted into the mounting holes, enabling the tip members at the two sides of the jaws to either distend or constrict in operation and thereby provide inner and outer diameter C-shaped snap ring installation and removal in various spatial operating environments.

摘要： 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.

摘要： 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. As such, the invention herein is an excellent enclosure for the said cluster mounted sand cloths that also provides for a rapid and guided procedure for replacing the sand cloths of vacuum-type rotary sanders.
