Abstract: A hollow-cylindrical portion (26) inserted in a hollow-cylindrical portion (16) of one rim section (12) is provided on the other rim section (13). To form a split rim (11), part (head portion) of the inner hollow-cylindrical portion (26) overlaid on the outer hollow-cylindrical portion (16) is radially outwardly expanded by being elastically deformed by a tapered surface (39) of a piston (38) such that the inner and outer hollow-cylindrical portions (16, 26) are in close contact with each other. As a result, relative positions of the rim sections (12, 13) are strictly defined, and this enables high assembling accuracy, particularly coaxiality with a high level, to be achieved. A fine fitted to the split rim (11) can be inspected with high accuracy.

Abstract: A torsional force structure of a ratchet device which includes a body having a head portion at an end of the body. The head portion has a space which is composed of a first recess and a second recess. A socket member is fitted in the first recess and having a plurality of teeth. A ratchet member is fitted in the second recess and provided at two ends thereof with two wedge portions configured to be fitted in an angular region between the inner wall of the space and the socket member. When the triggering rod is first adjusted to move the ratchet member to make one of the wedge portions of the ratchet member fit in the angular region and the the socket member is rotated, the wedge portion of the ratchet member will be forced to be tightly fitted in the angular region thereby enabling the socket member to provide a positive rotating force.

Abstract: A manual tool has a handle with two opposite ends that mount and demount a tire from a wheel. The first end has a rounded rectangular head for inserting between the bead and rim, when demounting a tire from a wheel. The second end is at an angle to the first end and has two spaced apart and parallel round heads that also insert between the rim and the bead, for mounting a tire. The tool, when either end is engaged between a bead and a wheel, is rotated about the axis of the wheel to mount or to demount a tire. The first end and the second end are made of a material of lesser hardness than a wheel thus preventing marring of the wheel.

Abstract: A light bulb changing tool is adapted for use with a conventional vacuum cleaner whose suction nozzle is of an indeterminate diameter. In some embodiments, the light bulb changing tool includes a rotational slip joint that enables the tool to be rotated while the vacuum cleaner is stationary. In some cases, the tool includes a torque-limiting coupling that allows the tool to exert greater loosening torque than tightening torque, thereby avoiding over tightening of the bulb and ensuring that the bulb can later be removed without breakage.

Abstract: A device for switching wrenching direction of a ratchet wheel of a ratchet tool. A ratchet wheel and a pawl are accommodated in a receiving cavity of the main body of the ratchet tool.

Abstract: A compact, ergonomic, pocket-sized bottle opener having a thin, generally flat body. The bottom edge of the body includes a jaw opening and at least one area for receiving a lifting finger. A plug of resiliently yielding material is mounted in the finger-receiving area to cushion the lifting finger. A hook at the forward end of the jaw opening forms a fulcrum point for engaging the top of the bottle cap. The hook also serves to lift pull-tabs on cans. An opening at the rear of the body holds a key ring. The key ring can be slipped into the opening during assembly by flexing the leg so as to open a slot that separates the distal end of the leg from the body. The cushioning plug mounts over both the distal end of the leg and the lower edge of the body so as to hold the leg in place after the ring has been installed. The two sides of the body form broad, generally flat display surfaces for application of logos, advertising, or other information.

A cover plate is disposed on a shelf recessed on the bottom of the wrench and spaced apart from the reversing lever.

Abstract: An easy storage precision screwdriver comprises a handle, a cover disposed on one end of the handle, a post disposed on the cover and located in the handle, a pressing ring threaded on the other end of the handle, and a working post inserted into the handle and fixed by the pressing of the pressing ring. Since the handle and the post are defined with a containing hole and a through hole respectively, when the user releases the pressing ring, the length of the working post with respect to the handle can be adjusted, and one end of the working post can be inserted into the containing hole and the through hole of the handle and the post. Thereby the precision screwdriver of the present invention is miniaturized, and is easy to store.
