Abstract: A bearing assembly tool for use in a bicycle comprises a contacting member, a handle, an engaging member, a screw, a press member, and a limiting member. By way of the screw, the contacting member and the engaging member, or the press member and the limiting member, a bearing can be assembled into or removed from a workpiece.

Abstract: A connector structure for connecting an electronic card includes an insulated body, a plurality of terminals, a seesawing mount and a resilient element. The insulated body has an opening with a plurality of holes formed on at least one wall of the opening. Each terminal has a contact portion for penetrating through a respective hole on the wall into the opening. The seesawing mount is furnished in the opening with a first end and a second end. The second end of the seesawing mount is located above the contact portions of the terminals. The resilient element has one end mounted on the insulated body and the other end pressing down the second end of the seesawing mount to press down the contact portions of the terminals. Whereby when inserting the electronic card in the insulated body, the electronic card pushes down the first end of the seesawing mount to lift up the second end of the seesawing mount so that the contact portions of the terminals can touch the electronic card.

Abstract: An electronic card connector including an insulating body, a shielding member and a pushing assembly is disclosed. The insulating body includes a one-way track with a forwarding portion, a positioning portion, and a returning portion. The shielding member includes a spring leaf with a recessed rail corresponding to the forwarding portion. The free end of the spring leaf is bent to the forwarding portion and forms a tilt toward the positioning portion. The pushing assembly includes a guide lever with a first protrusion and a second protrusion for slidably moving in the one-way track and the recessed rail, respectively. As such, when the electronic card is inserted, the second protrusion is guided by the tilt to rest in the positioning portion; and when the electronic card is ejected, the first protrusion is guided in the returning portion back to the forwarding portion.

Abstract: An IC card connector includes a insulation housing holding two symmetrical rows of terminals at front and rear sides, the terminals each having a contact portion suspended inside the insulation housing, and an actuating member pivoted to the inside of the insulation housing and adapted for pressing the contact portions of the terminals on respective contacts of the IC chip of an IC card upon insertion of the IC card into the insulation housing and for enabling the contact portions of the terminals to be returned to their former position by spring power of the terminals upon removal of the inserted IC card from the insulation housing.
