The bow frame has a longitudinal slit and the handle has a limited space including an opening in outer side, a plurality of ribs on inner side, a first and second pivot holes respectively in an upper and a lower wall and a through hole in the front of the limited space. A radial fixture is engageable into the limited space and having an axial hole engaged with the pivot holes and rotatably secured by a rivet. It is characterized in that turns in the radial fixture into the limited space, its protruded stopping surface in cooperation with the ribs will clamp the saw blade very tight without loosening.

Abstract: A handsaw includes a handle combined with a first and a second halves each having a large circular hole in front end wherein the first half has a protrudent ring together with a plurality of positioning grooves in the inner periphery of the large circular hole and an elongate receiving space in inner surface and the second corresponding half has inner threads in the large circular hole, an angular adjustment device disposed in the front end of the handle between the large circular holes and composed of a turning member, a circular clamping plate biased by a spring, a saw blade having an inner end secured to a retaining rod and a rectangular protrusion on the other side of the clamping plate and a cup-shaped fastener stopping against the circular clamping plate and the saw blade through the large circular hole of the second half.

Abstract: A blade gripping mechanism in a heavy duty artistic knife includes a straight handle combined with a first and a second halves and secured by a pair of screws. The straight handle has a tubular projection in front end for elastically disposing a positioning member which has a pair of tenons symmetrically formed on opposing outer peripheries and a rectangular receiving space in rear end for releasably disposing a tool box therein. A head has a first annular ring on rear end sleeved on the tubular projection including two pairs of mortises in an inner flange made engageable with the tenons and an annular gap in communication with a flat gap in the body. A blade rack having a second annular co-axially sleeved on the tubular projection together with the first annular ring and a blade disposing space in side of a flat upright for placing a blade therein. When changing a new blade, press the blade rack downward to have it rotating out of the flat gap and then push it in again after the changing of the blade.

Abstract: A quick disassembly hacksaw includes an inverse U-shaped frame having a flexible triangular front handle on fore end, a rear handle on rear end, a front tube and a rear tube respectively disposed under the fore end and rear end, an adjusting mechanism disposed in the front tube, a positioning rod inserted into the rear tube each of which has a polyhedron for connecting a saw blade and a fastening mechanism comprised of a link and a U-shaped leverage latch pivoted to the positioning rod and a lug under the rear handle and locked by a safety detent on a top of the rear handle. The saw blade is fastened by the fastening mechanism and the tensions thereof is adjusted by the adjusting mechanism.

Abstract: An artistic knife with adjustable handle includes a straight handle which is combined with a pair of first and second halves, a head rotatably gripped by the straight handle and having a blade on front end and an annular ring on rear end sleeved on a tubular projection of the first half. The annular ring has an inner flange in which a plurality of pairs of mortises are symmetrically formed. A positioning member disposes into the tubular projection and biased by a spring and has a protrudent surface engaged within a circular through hole of the second half through the annular ring and a large tenon and a small tenon on opposing outer peripheries respectively engaged with the mortises. Thereby, press the positioning member inward to enable the head to rotate a certain degree of angle between the head and the straight handle. Then release the positioning member which controls the movement of the head.

Abstract: A structure of a hammer includes a hammer-head engaged with a handle which is combined by a pair identical halves to form a nail chamber in rear end, a tunnel extending from the nail chamber to a slit in front end of the handle and intercepted by a vertical slot into which is a control button to control the nail from going through the tunnel, an exit in front end of the handle beneath the slit, a magnet disposed under the exit and a cylinder cavity in the back of the exit for disposing a counterblow mechanism therein. The hammer of the present invention further have a nil magazine and a trumpet tube for serving small sized nails.

Abstract: A structure of a hacksaw includes a frame which is combined by a fore part and a rear part, an adjustable mechanism under the fore part connected to one end of the blade for adjusting the tilt angle of the blade, a positioning mechanism under the rear part connected to the other end of the blade and for tensioning the blade by a wedge lever. The frame disassembly to quickly adjust the length to serve different lengths of the blade.

Abstract: A combinable scriber knife includes a handle combined with a main housing and a subordinate housing. The main housing has a slotted lock at a first end engageable with a locking plate at a first end of the subordinate housing, a U-shaped hook pivoted at a second end including a locking knot on inner side engageable with a locking hole in a second end of the subordinate housing, a pair of coupling posts on an inner side engageable with a pair of coupling holes in an inner side of the subordinate housing, a plurality of chambers inside the main housing to receive a plurality of the hexagonal shanks of screwdriver which are engageable within a hexagonal central bore at the second of the main housing and a trapezoid shaped blade inserted into the slotted lock and retained by a knot inside the main housing.

Abstract: A quick disassembly device for a heavy duty artistic cutter includes a handle combined with a pair of first and second half casings. The first half casing has a reduced end insertible into a vertical slot at a corresponding end of the second half casing. A circular depression is formed in the other end of each of the half casings including different slot in their bottoms for respectively engaging with rectangular latch and a positioning post from a fastener which fastens the two half casings together, a rectangular depression including a blade entrance in the top of the handle for slidably disposing a slidable blade rack therein.

Abstract: A cutter blade dispenser and disposer with slide biasing means and side located dispensing slot comprising a body, a sliding block and a side compartment. The body is a trapezium case and can room a plurality of blades, an elongate slit rail is disposed on top of the body, inside the body has a pillar for an elastic element to sleeve on, an elastic block is disposed on top of the opening of the body. The sliding block is in trapezium shape for fitting inside the body with an inclined piece and a pressing block disposed on its top. The side compartment is also in trapezium shape and can cover the opening of the body, a locking hole is disposed on top of the side compartment with a sliding hole and an elongate slit on its one side. The sliding hole and the elongate slit are in one through passage. A storage board is disposed underneath the sliding block and inside on the bottom of the body. The storage board has a protrusion bar on its each side for placing the blades in decency and order.
