Referring to fig. 1 and 2, a digital chip mounting groove 90 for mounting a digital chip 91 is formed in the key handle of the tooth-shaped key 9 matched with the lock head, and the required digital chip 91 can be mounted in the digital chip mounting groove 90 according to the requirements of lock manufacturing. And then the lock can be used after being packaged according to the existing lock manufacturing process and technology.

When in use:

when the key switch 7 or the electric control pin 8 is not used, the permanent magnet 81 can not fall into the locking groove 18 due to the action of the magnetic reset spring 83, and at the moment, the lock with the immovable lock core is a lock controlled by a pure mechanical key. When the matched key 9 is correctly inserted into the key slot 268 to realize unlocking or locking, the appointed groove 29 and the side column slot 20 are aligned at the moment, only external force is needed to press the stress point 19, and the sliding piece 1 is driven to slightly move towards the locking direction, so that the locking side column 30 loses the friction force between the side column slot 20 and the locking slot 11 generated by the unlocking spring 33, the locking side column 30 moves towards the groove 29 and is completely arranged in the side column slot 20 under the action of the locking side column pressure spring 14, at the moment, no object is clamped between the lock core 2 and the sliding piece 1 according to the appointment, at the moment, the sliding piece 1 can vertically slide relative to the axis of the lock core 2 and move towards the unlocking direction until the lock head is in an unlocking state, and the unlocking mechanism 16 is driven to move, so that corresponding unlocking work is implemented. When the lock is locked, the stress point 19 is pushed by external force to enable the sliding part 1 to be located at a locking position, the locking clamping groove 11 of the sliding part 1 corresponds to the side column groove 20 of the lock cylinder 2, the key can be pulled out at the moment, the groove 29 and the side column groove 20 are in different positions under the action of tooth profile transformation or outer edge or side column spring 266 of the key, the outer side of the locking side column 30 enters the locking clamping groove 11 and is matched with the locking clamping groove 11, and the locking side column 30 is clamped between the sliding part 1 and the lock cylinder 2, so that the lock head is locked.

When in use:

when key switch 7 or automatically controlled pellet shot from a slingshot 8 are used for the control unit's of tool to lock system circuit to make normal connection and implemented normal work with the control unit who establishes in the tool to lock system, this moment the utility model discloses a lock that lock core rigid's tapered end is a mechanical key and the tapered end that digital chip cipher key together controlled to unblank. Fig. 2 is a schematic structural diagram of the present invention for expanding application, in fig. 2, when the key 9 containing the digital chip 91 is inserted into the key slot 268, the key 9 presses the contact 71 of the key switch 7, so that the key switch 7 is closed, and the control unit 5 is powered on, at this time, the control unit 5 controls the key code reading module 51 to read the password information of the digital chip 91 in the key 9, and compares the password information with the original password information in the storage module 52, if the password information is the same, the lock with the immovable lock core of the present invention is equivalent to a lock controlled by a purely mechanical key; if the password information is different, the control unit 5 controls the cylinder of the permanent magnet 81 in the electric control pin 8 to pop out and cooperate with the locking groove 18 on the sliding member 1 to lock the sliding member 1, so that the sliding unlocking cannot be realized. And the control unit 5 can send out an alarm signal to the near or far.

In practical application, in order to prevent the key stored in the digital chip 91 from being intercepted and copied, the digital chip 91 and the control unit 5 are set to have 433 module combination which has strong security and is difficult to intercept and copy and a communication protocol matched with the 433 module combination, so that when the key 9 containing the digital chip 91 is inserted into the key slot 268, the key 9 presses the contact 71 of the key switch 7, so that the key switch 7 is closed, the control unit 5 is powered on, at this time, the control unit 5 sends a random number to the digital chip 91, and at the same time, the control unit 5 also temporarily stores the random number, when the digital chip 91 receives the random number, the control unit 5 immediately performs formula operation and sends the operation result to the control unit 5, and at the same time, the control unit 5 also compares the temporarily stored random number with the random number of the digital chip 91 by performing the same formula operation on the random number and the two operation results, if the password information is the same, the lock with the immovable lock core of the utility model is equivalent to a lock controlled by a purely mechanical key; if the password information is different, the control unit 5 controls the cylinder of the permanent magnet 81 in the electric control pin 8 to pop out and cooperate with the locking groove 18 on the sliding member 1 to lock the sliding member 1, so that the sliding unlocking cannot be realized. The clock module 53 can be used for recording the unlocking time, so that the system management is convenient.

The above embodiments are not intended to be limiting illustrations of the concepts and applications of the present invention. The utility model discloses can use alone as required, also can be used to in the intelligent tool to lock. In practical application, the utility model discloses can with patent number 201720119237.0, the patent name "a can prevent the fixed tapered end of lock core of external force impact" in the technology ally oneself with uses.
