Abstract: The present invention relates to an electrical receptacle having a safety mechanism. The electrical receptacle includes a latch installed internally, where the latch is operated through a switch member positioned externally. The latch can be switched to a locking position or an unlocking position by the switch member. In the locking position, the plug is constrained to be unplugged or the plug is restricted to be inserted. In the unlocking position, the plug is free to be inserted or unplugged.

Abstract: A tool device includes a main body, a cutting member and a locking mechanism. The main body is formed with a receptacle for receiving the cutting member. The cutting member is movably mounted on the main body and selectively moves between a first position of being received in the main body and a second position of being removed from the receptacle and ready to use. The locking mechanism is mounted on the main body and changeable between a locking mode and a release mode. In the locking mode, the cutting member cannot be moved from the first position to the second position. While, in the release mode, the cutting member is free to move to the second position for use.

Abstract: A status indicator for a lock includes two locking units that operate independently, to execute locking and unlocking operations. The lock has a body, which contains an indicator and a brake bolt. The indicator is latched by the brake bolt to remain at a selected indication position. When one locking unit executes the unlocking operation, the indicator is driven concurrently to switch to another indication position corresponding to a window, and is latched by the brake bolt without returning. The brake bolt can only release the latch condition on the indicator through the unlocking operation of another locking unit. Likewise, the indicator returns to the original indication position. Thus through the window formed on the body surface, the indication position of the indicator may be recognized.

Abstract: A connection lock capable of executing locking operation without keys includes a case to house an actuation mechanism, a rotary cylinder and an elastic element. The actuation mechanism includes a movable leg and a fixed leg. The movable leg is moved by the elastic element to be close to the fixed leg at an unlocking position in normal conditions. The rotary cylinder has a nudging member extended from the front end that can move the movable leg away from the fixed leg at a locking position. The case has a one-way hump corresponding to the rotary cylinder to allow the rotary cylinder to be turned in one way to switch the movable leg from the unlocking position close to the fixed leg and to the extended and locking position.

Abstract: A retractable wire lock includes cables or steel wires of different lengths to serve as connection members to couple with a first guarding member and a second guarding member, and a winding reel pivotally located in a casing to couple with and wind the connection members. The winding reel can adjust the length of the connection members according to actual requirements or fully wind the connection members for storing.

Abstract: A combination lock having a combination lock mechanism and a key lock mechanism. The combination lock mechanism is able to unlock and lock the combination lock by switching a plurality of dials exposed on the surface of the combination lock, while the key lock mechanism allows the user to unlock the combination lock with a key.

Abstract: A laptop computer lock includes a primary body having a tapered extension extending outward from the primary body and having a through hole defined through the tapered extension. A secondary body is movably received in the primary body and has a linkage extending out of the primary body. A retaining device is received in the primary body and has a leverage operably engaged with the linkage so that the leverage is able to pivot relative to the secondary body. The tapered extension of the primary body increases available space for a securing device to secure the laptop computer without tilting the laptop computer.

Abstract: The present invention is related to the locking device with extending functions, a body of the locking device can optionally connect different additive members, such as an article with a hanging hole, a timer, a compass, a thermal meter, etc.

Abstract: A locking device for a compact computer or a small computer, in particular, a personal data accessory or a palm data accessory (hereinafter referred to as PDA), is presented. The invention also includes a blocking device which is connected with the locking mechanism and is convertible between an unlocking position and a locking position, the blocking device is adapted to be locked and secured by the locking mechanism. The blocking device is adapted to be set to the locking position and resist against the incline surface of the stand so as to lock and secure the PDA with the stand.
