A linear motion damping device comprises a cylindrical body having a receiving compartment and an axial hole, in which a dragging rod is slidably disposed such that the threaded portion of the dragging rod is engaged with a fastening member which is confined to turn around the dragging rod at such time when the dragging rod is exerted on by an external force along the axial direction of the dragging rod. The fastening member acts to provide the dragging rod with a damping force at the time when the dragging rod is engaged in a displacement along the axial direction thereof.

Linear motion damping device

An adjustable torsion damper has a mount which is divided in the longitudinal direction thereof into two submounts made of a material conductive to magnetism. Located between the two submounts is a portion nonconductive to magnetism. The mount is provided at an upper end thereof and a lower end thereof with a first round hole and a second round hole. The first round hole runs between the submounts. A magnetic block is rotatably disposed in the first round hole. A rotary shaft is rotatably disposed in the second round hole. The rotary shaft is made of a material conductive to magnetism. The value of torsional moment of the rotary shaft changes along with the magnetic block in motion.

A screwdriver is composed of a handle, a magnetic member, a shank, and an adjusting device. The handle is provided with an axial hole in which the magnetic member is disposed. The shank is pivotally disposed in the axial hole such that the shank is fastened at one end thereof with a blade, and that another end of the shank is capable of a mutual attraction with the magnetic member. The magnitude of the mutual attraction is adjusted by the adjusting device to determine a pre-set desired torsional moment. The handle and the shank are capable of turning relative to each other at the time when a torsional moment exerting on the screwdriver is greater than the pre-set desired torsional moment.

A device for stopping automatically an overloaded lathe comprises a support base, a front holding base, a rear holding base eccentric cam, a locating block, and a lathe tool. The front holding base is fastened with the front end of the support base by means of a screw which is fitted over by a resilient washer. The lathe tool has a handle which is fastened at the front end thereof with the front holding base. The rear holding base eccentric cam is fastened with the rear end of the support base by means of a screw which is fitted over by a resilient washer. The handle of the lathe tool is urged at the rear end thereof by the rear holding base eccentric cam. The locating block is fastened with the support base and is provided with a proximity switch having an electric circuit connected with the electric circuit of the main shaft motor of the lathe. The rear end of the handle of the lathe tool is urged by the locating block.

A method and a device for preventing a drilling chip from winding around a drill bit and for removing the drilling chip deposited in flutes of the drill bit comprising a drill bit acting as a driving member and a driven gear having at least one tooth engageable with flutes of the drill bit. As the drill bit is turned to drill a hole, the driven gear is actuated to turn such that the tooth of the driven gear engages the flute of the drill bit so as to scrape off any drilling chip deposited in the flute of the drill bit and to prevent the drilling chip from winding around the drill bit in action. The driven gear is rotatably and movably fastened to a support rod which is in turn fastened to a drill press.
