Abstract: An improved USB connector extension/retraction device for a USB flash drive includes a moving cover for coupling with a flash memory unit (which has a USB connector), a resilient bar element, and two springs. The moving cover is assembled with a railed housing to form the USB connector extension/retraction device. The moving cover can be pushed forward and secured in position so that the USB connector of the flash memory unit is extended out for use. When not in use, the USB connector is retracted automatically so as to be hidden for protection. In addition, the USB connector extension/retraction device allows the USB flash drive to have a reduced volume.

Abstract: A flaring device for flaring a hollow malleable tubular member is provided. A hydraulically powered assembly includes a main body having a cylinder, a lever and a piston member which is received in the cylinder. The main body has an axis and opposing first end and second end. The lever is pivoted on the first end of the main body and operable to drive the piston member to move along the axis. One end of the piston member is formed with a conical expander. The die set is disposed at the second end of the main body and has a plurality of die elements arranged around the axis. The conical expander of the piston member is actuated to move axially and outwardly so as to radially drive the die elements to flare the hollow malleable tubular member.

Abstract: A tube bender is provided. The rotatable member is pivoted to a pivot portion of a base and defines an inner space, and the rotatable member has a gear portion, a first arched groove and a holding portion. The gear portion archedly extends around the pivot portion. The first arched groove archedly extends around the pivot portion on an outer circumferential surface of the rotatable member, and the holding portion has a holding recess. The abutting assembly includes an abutting chunk assembled to the base and an arm member connected with the abutting chunk. A gear assembly includes a driving portion pivoted to the arm member and a gear connected and synchronously-movable with the driving portion. The gear engaged with the gear portion in the inner space.
