wherein the main body has a shell which comprises two pieces to fit together, and at least an inner surface of the shell has a first housing and a second housing which are communicated through a connecting channel; two ends of the shell respectively have a first opening and a second opening axially penetrating through the shell, and the second housing comprises a first securing portion formed therein; the main body is connected to a lock cable which is configured to be wound around an immovable object to achieve the burglarproof effect of the lock;

wherein the lock barrel installed in the first housing of the main body comprises a lock bolt which is adapted to axially protrude from the first opening to stick out of the shell when the lock is at an unlocked position;

wherein the connecting member has a base, and an ear portion is formed at an end of the base, and an elongated pivot hole vertically penetrates through the ear portion; the connecting member is positioned in the connecting channel of the shell, and the base is connected to the lock bolt in the connecting channel;

wherein the first engaging member has a first section and a second section which are connected together to form a designed angle bend, and the first section comprises a second securing portion thereon; the first engaging member is positioned in the shell, and the second securing portion is connected to the first securing portion, and the first section of the first engaging member is positioned in the second housing, and the second section is configured to protrude from the second opening to stick out of the shell; the second section has a gradually larger diameter outwardly from the shell, and a first lateral surface of the second section close to the second engaging member comprises a guiding portion, and an engaging block is adapted to protrude from a second lateral surface of the second section which is located far from the second engaging member; and

wherein the second engaging member comprises a connecting portion which is configured to pivotally connect to the pivot hole of the connecting member in the connecting channel; a lock rod protruding from an end of the connecting portion is located a position deviated away from a central axis of the connecting portion; a lateral edge of the lock rod close to the first engaging member comprises a driven portion which is coupled with the guiding portion of the first engaging member such that the lock rod is adapted to be driven by the lock bolt and moved along the first lateral surface of the second section; the lock rod is adapted to be moved by the lock bolt to protrude from or back in the second opening so as to achieve locking and unlocking effects.

2. The lock for electronic devices of claim 1 , wherein a lateral edge of the second opening comprises an inclined surface to guide the lock rod when protruding from and moving back in the second opening.

3. The lock for electronic devices of claim 1 , wherein the lock cable has a ball head at an end thereof which is configured to pivotally connect to the shell of the main body such that the ball head is adapted to rotate in the shell to enable the lock cable to be positioned in multiple directions.

4. The lock for electronic devices of claim 1 , wherein the second securing portion is a hole, and the first securing portion is a bolt which is configured to penetrate through and engage with the second securing portion.

5. The lock for electronic devices of claim 1 , wherein the lock barrel is a key lock barrel.

6. The lock for electronic devices of claim 1 , wherein the lock bolt of the lock barrel is engaged with the base of the connecting member.

7. The lock for electronic devices of claim 1 , wherein the first section and the second section of the first engaging member are connected together to form 90-degree angle bend.

8. The lock for electronic devices of claim 1 , wherein the engaging block is shaped into a triangle wedge.

9. The lock for electronic devices of claim 1 , wherein the connecting portion is a hook which is adapted to hook on the pivot hole such that the second engaging member is pivotally connected to the ear portion of the connecting member in the shell of the main body.

10. The lock for electronic devices of claim 1 , wherein the guiding portion and the driven portion are formed into a step edge and coupled together, such that the second engaging member driven by the lock bolt is adapted to be moved along the second section of the first engaging member.
