Abstract: A vehicle unlocking device includes a first rod, a second rod, a first connecting member, a second connecting member, and a lock device. Therein, the first rod has one end as a handle and the other end as a first fixing part. The second rod has one end as a bended hook part and the other end as a second fixing part. The first connecting member is fixed to the first fixing part. The second connecting member is fixed to the second fixing part and sleeves the first connecting member, while the first and second connecting members are kept from rotating against each other. The lock device is in between the first and second connecting members for manipulating the axial detachment of the second connecting member from the first connecting member.

Abstract: A triangle ruler includes a triangle ruler body defining three corners, three sides, opposing first surface and second surface surrounded by the three sides and three corners and a recessed annular scale located at the center thereof, and a direction indicator including a pendulum and a pointer and pivoting about the center of the recessed annular scale in such a manner that the pivot axis of the direction indicator extends perpendicular to the first and second surfaces of the triangle ruler body, and the effects of the weight of the direction indicator keeps one end of the pointer to constantly indicate a predetermined direction. Thus, the invention combines the functions of a conventional protractor and a conventional triangle ruler to facilitate drawing a variety of different angles of lines.

Abstract: A triangle ruler includes a triangle ruler body defining three corners, three sides, opposing first surface and second surface surrounded by the three sides and three corners and a recessed annular scale located at the center thereof, and a direction indicator including a pendulum and a pointer and being pivotally connected to the center of the recessed annular scale in such a manner that the axial direction of the direction indicator passes through the first and second surfaces of the triangle ruler body, and the effects of the weight of the direction indicator keeps one end of the pointer to constantly indicate a predetermined direction. Thus, the invention combines the functions of a conventional protractor and a conventional triangle ruler to facilitate drawing a variety of different angles of lines.

Abstract: A cutting tool with an adjustable cutting angle includes a first shank ended by a cutting blade, a second shank pivotally connected to the first shank so that the first and second shanks can be drawn toward or away mutually, an anvil provided on the second shank in positional correspondence to the cutting blade so as to work with the cutting blade and cut, wherein the anvil having a board-like body extending along the second shank is formed with an axial hole and edged with a curved sliding rim, and a pivotable retaining plate having its one end mounted around a shaft in the axial hole and its opposite end formed with a notch for engaging with the sliding rim, so that the pivotable retaining plate can pivot against the anvil, thereby making an angle between the retaining plate and the cutting blade, namely the cutting angle vary.

Abstract: A beveled-edge maker (1) for chamfering a workpiece (2), the tool comprising a knife assembly (4) adapted for attaching to a drive (5), and at least one guider (8) adapted such that the beveled-edge maker can be mounted to the edge of the workpiece and moved there along.

Abstract: An innovative cutter-grinder comprised of a base, a cutter holder, and a mobile base plate; the base plate being mounted with emery cloth before being placed on a deck of the frame to secure the emery cloth and allow easy replacement of the emery cloth; the cutter holder adapted with a roller at bottom retaining a blade for the user to hold the cutter holder to roll back and forth on the base plate to grind the cutter against the emery cloth; and an angle set plate being inserted onto slots respectively provided on both sides of the deck allowing the adjustment of the grinding angle.

Abstract: An angle adjustable sawing table adapted to allow the installation of a circular saw. Wood material is placed at pre-set geometric angles. One end of a gage is placed on a table, and another end of the gage is flush against a measurement member for adjustment to a preset angle.

Abstract: An angle adjustable sawing table allowing interchange of displacement among measurement members on the table to compromise the installation of the circular saw; the wood material being place at pre-set geometric angle; one end of the gage being placed on the table, and another of the gage flushed against the measurement member for adjustment to meet the present angle for easier cutting and time-saving.

Abstract: A carpenter's combination plane comprised of a basic holder and a blade holder, adapted with various holder accessories depending on the size of the work surface and the distance of reciprocal planing; other auxiliary accessories may be provided to the holder accessories to define the width, depth, inclined surface of the work surface or the polishing work surface.
