At the same time, by arranging the hose 11 on the outside of the flexible shaft 6, the flexible shaft 6 can be effectively protected.

[0036] Specifically, the flexible shaft 6 is preferably a double-layer structure, that is, the flexible shaft 6 is divided into an inner flexible shaft 6 and an outer flexible shaft 6, which are mutually sleeved and coaxially arranged together. By setting up the double-layer structure of the flexible shaft 6, the structural strength of the flexible shaft 6 can be greatly improved.

[0037] It can be seen that in this embodiment, a handle 5 is provided, a freely bendable soft shaft 6 is provided at one end of the handle 5, and the soft shaft 6 is connected to a key head 7, so that the lock body is unlocked by the lock head; specifically, when in use, the key head 7 is driven to extend into the restricted lock hole space through the bendability of the soft shaft 6, so that the key head 7 can be effectively inserted into the lock hole, and the lock body can be unlocked by operating the handle 5, thereby effectively unlocking the lock body with restricted lock hole space, which not only improves the anti-theft performance, but also improves the unlocking efficiency.

[0038] Furthermore, in this embodiment, by providing a detachable key head 7, a corresponding key head 7 can be installed according to different types of lock cores, thereby improving the versatility of the key and greatly reducing the manufacturing cost and the user's use cost.

[0039] Another preferred implementation based on the above embodiment, in this implementation, when the passive anti-theft lock is unlocked electronically, the key head 7 in this implementation includes an electronic key head 71, which is used to be inserted into the lock hole on the lock body to unlock the lock body.

[0040] Combination Figure 2 and 3 As shown, the electronic key head 71 is provided with a through hole along its axial direction, and a current needle 13 is provided in the through hole. The current needle 13 is used to connect with the electric signal receiving unit in the lock hole so that the key communicates with the lock body, and the current needle 13 is also used to transmit electric energy to the lock body; a wire 16 is passed through the inside of the flexible shaft 6, and the current needle 13 is connected to the handle 5 through the wire 16. It can be understood that the electric signal receiving unit in the lock body is used to receive the communication signal and power supply current output by the key, so as to power the lock body through the key. Specifically, the current needle 13 includes a positive pin and a negative pin. The current needle 16 is fixed in the groove provided at the second end of the electronic key head 71 through an insulating sleeve 14, and a blocking object 15 is provided at the connection between the current needle 13 and the wire 16.

[0041] Specifically, a power supply unit is provided in the handle 5, and the power supply unit is connected to the current needle 13 through a wire 16. The power supply unit is preferably a lithium battery, and the lithium battery is connected to the current needle 13 through a wire 16, so that the lock body of the passive anti-theft lock is powered by the lithium battery in the handle 5.

[0042] Specifically, an identification unit is also provided in the handle 5, which is used to collect at least one of the user's voiceprint information, fingerprint information, facial information and password information, and perform identity authentication based on the collected information. When the identity authentication is passed, an unlocking command is output, and the unlocking command is transmitted to the lock body through the current needle 13 for response.

[0043] Specifically, the recognition unit includes a voiceprint acquisition module, a fingerprint acquisition module, an image acquisition module and a password acquisition module, through which voiceprint information, fingerprint information, facial information or password information are respectively acquired. Preferably, the voiceprint acquisition module is a microphone, the fingerprint acquisition module is a fingerprint collector, the image acquisition module is a camera, and the password acquisition module is a password collector.

[0044] Specifically, the voiceprint acquisition module, fingerprint acquisition module, image acquisition module and password acquisition module are respectively connected to a processor, and the processor is used to receive the information collected by the voiceprint acquisition module, fingerprint acquisition module, image acquisition module and password acquisition module, and perform identity verification based on the collected information. When the identity authentication is passed, an unlocking instruction is output, and when it fails, an alarm instruction is output.

[0045] Specifically, the processor can be set in the handle 5, and the processor is connected to the unlocking device in the lock body through the wire 16 and the current needle 13, that is, the processor in the handle 5 is connected to the unlocking circuit in the lock body through the wire 16 and the current needle 13. When the identity is successfully passed, the unlocking instruction output by the processor is output to the unlocking circuit in the lock body for unlocking operation; when the identity authentication fails, the alarm instruction output by the processor is output to the lock body, and the alarm unit in the lock body alarms the user according to the alarm instruction.

[0046] Specifically, the processor can also be set in the lock body. When the processor is set in the lock body, it is only necessary to output the information collected by the voiceprint collection module, fingerprint collection module, image collection module and password collection module in the handle 5 to the processor in the lock body through the wire 16 and the current needle 13, and the processor in the lock body will then perform identity authentication.

[0047] Specifically, when in use, by holding the handle 5, the flexible shaft 6 drives the key head 7 to connect with the keyhole in the confined space. After the key supplies power to the lock body, the lock can be unlocked after identity authentication.

[0048] It can be seen that the key in this embodiment can not only effectively power the passive anti-theft lock, but also effectively solve the problem that the passive lock sets the keyhole in a confined space to improve the anti-theft performance, so that the anti-theft lock with a confined space can be effectively unlocked to improve the unlocking efficiency; at the same time, by setting an identification unit on the handle 5 to unlock the lock body according to the voiceprint information, fingerprint information, facial information or password information collected by the key, the convenience of unlocking can be greatly improved. At the same time, when the criminals do not have the key, they cannot quickly crack the lock body, which greatly increases the difficulty of illegal cracking and improves the anti-theft performance.

[0049] Another preferred implementation manner based on the above embodiment, in this implementation manner, when the anti-theft lock or electronic anti-theft lock is mechanically unlocked, since the anti-theft lock or electronic anti-theft lock has a confined space at the keyhole, the key of this implementation manner can effectively unlock it.

[0050] Another preferred implementation based on the above embodiment, in this implementation, when the electronic anti-theft lock needs to be unlocked, it can be unlocked by the key of the electronic structure described in the above embodiment. When electronic unlocking is performed, after the electronic key head 71 is inserted into the lock hole of the lock body, the electronic key head 71 supplies power to the lock body, and identity authentication is performed through the identification unit. At the same time, the key can be set to rotate a certain angle before powering on and unlocking the lock body as needed, thereby improving security. That is, after the key is inserted into the lock hole, the key is rotated a certain angle, and then the key communicates with the lock body to unlock.

[0051] Combination Figure 4 As shown, in this embodiment, the key head 7 includes a mechanical key head 72, one end of which is detachably connected to the flexible shaft 6, and the connection method between the mechanical key head 72 and the flexible shaft 6 is the same as the connection method between the key head 7 and the flexible shaft 6 in the above embodiment, which will not be repeated here.

[0052] Specifically, the other end of the mechanical key head 72 is a traditional key head 7 structure, and the other end of the mechanical key head 72 is connected to the key hole on the lock body, so as to mechanically unlock the lock body. When in use, the handle 5 is operated to drive the mechanical key head 72 into the confined space through the flexible shaft 6, and the detachable key head 7 is inserted into the key hole on the lock body. The handle 5 drives the flexible shaft 6 to rotate, and the mechanical key head 72 is used to rotate synchronously with the flexible shaft 6 under the drive of the flexible shaft 6 to lock or unlock the lock body.

[0053] It can be seen that the key structure in this embodiment, by providing a mechanical key head 72, can efficiently unlock a traditional anti-theft lock set in a confined space. At the same time, when the electronic anti-theft lock set in the confined space is insufficient in electrons and cannot be unlocked electronically, the key of this embodiment can be used to quickly and effectively unlock the lock, which not only improves the anti-theft performance, but also greatly increases the unlocking efficiency.

[0054] Specifically, since the flexible shaft 6 is a universal component, it is only necessary to set the handle 5 and the key head 7 according to different unlocking requirements, thereby greatly improving the versatility of the key in this embodiment, and can also effectively reduce the manufacturing cost and the user's expenses.

[0055] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
