Abstract: A lock is provided, including: a housing; a latch member, movably mounted to the housing and including a first blocking portion; a blocking member, movably mounted to the housing and including a second blocking portion; a locking member, operably mounted to the housing; wherein when the locking member is in a locking state and the latch member is in a first position, the locking member and the blocking member are free of blocking from each other so that the first blocking portion and the second blocking portion are blocked with each other, and the latch member is unmovable toward a second position; when the locking member is in a unlocked state, the second blocking portion and the first blocking portion are unblocked with each other and the latch member is movable to the second position so that the latch member is retractable from a locked object.

Abstract: A lock is provided, including a sleeve member, a main body and an engaging member. The main body is rotatably disposed in the sleeve member and has a first connecting portion, one of the main body and the sleeve member has a slide slot which extends along an axial direction and the other has a protrusive block, when the protrusive block corresponds to the slide slot in the axial direction, the main body is movable relative to detachable from the sleeve member. The engaging member is rotatably disposed in the sleeve member and has a second connecting portion, one of the engaging member and the main body has a hook and the other has a slot, when the first and second connecting portions are assembled to each other, the engaging member and the main body are co-rotatable, and the hook is engaged with the slot.

Abstract: A connection lock is provided. A driving assembly is disposed to a shell body, is movable to be in first or second positions and further has a restricting portion. A lock device is disposed to the shell body and includes a lock member which is movable relative to the shell body to be in unlocked or locked positions and has a tendency to move toward the locked position. An actuating member is slidably disposed in the shell body. A first elastic member is disposed in the shell body and abuts against one of the actuating member and the driving assembly to bias the driving assembly in a direction toward the first position. A engaging assembly is disposed in the shell body and is movable to be in released or engaged positions and is configured to be inserted into an anti-theft hole of an object.

Abstract: A connection lock includes an adapting assembly including an outer sleeve and an adapting member, a first connecting member including a first outer tube and a first cable, a lock structure connected to the first cable, second connecting members each including a second outer tube and a second cable, and engaging structures for anti-thefting of a 3C product. The first outer tube is connected with the outer sleeve, and the first cable is connected to the adapting member. The lock structure is movable to a locked position or an unlocked position. Each second outer tube is connected with the outer sleeve, and each second cable is connected to the adapting member. Each engaging structure is connected to one said second cable and movable between an engaged position and a released position so that each engaging structure, the adapting member and the lock structure are comovable.

Abstract: An engagement structure for a cable head includes a main body and a release mechanism. The main body has movable positioners disposed thereon. When the cable head is inserted in the main body, the positioners are temporarily pushed away and moved back by an elastic mechanism to block the cable head from removing from the main body. For removing the cable head, a release mechanism is configured for pushing the positioners away. Thus, user can remove the cable head by operating the release mechanism. Therefore, operation of the engagement structure is simplified for user.

Abstract: An antitheft device includes a cover, a base plate, and an adhesive element. The base plate is located in a receiving space of the cover and is adapted for a controlling element to connect thereto to release or lock the cover and the base plate. The base plate is able to be adhered onto an object to be secured by the adhesive element. The adhesive element is also located in the receiving space of the cover so that the adhesive element is prevented from being removed or broken easily.

Abstract: An engagement structure for cable head of the present invention includes a main body, a cable head, and a release mechanism. The main body has movable positioner disposed thereon. When the cable head is inserted in the main body, the positioner is temporarily pushed away and is moved back by an elastic mechanism to block the cable head from removing from the main body. For removing the cable head, a release mechanism is configured for pushing the positioner away. Thus, user can remove the cable head by operating the release mechanism. Therefore, operation of the engagement structure is simplified for user.

Abstract: The present invention provides a lock structure of plug of cable including a main body and a key. The main body has a locking area, an elastic area with an elastic element, and a lower room which is able to receive a plug of cable. The elastic element tends to stay at a first position. When the key is not inserted into the locking area, the elastic element is at the first position, and a latch of the plug of the cable is unable to be compressed due to the fixation by the elastic element. When the key is inserted into the locking area and is rotated, the elastic element is pushed to a second position, and the latch is able to be compressed. Thereby, the lock structure of plug of cable can be used to control the availability of the plug for a jack.
