The guide surface is an arc surface or an inclined surface.

The outer side wall of the rotating sleeve 3 is provided with a stop groove 31, an electromagnetic device 5 is arranged in the shell, the electromagnetic device 5 is connected with a locking rod 51 aligned with the stop groove 31 and can control the extension and retraction of the locking rod 51, and the locking rod 51 is clamped in the stop groove 31 so as to limit the rotation of the rotating sleeve 3.

The top of the knob cap 2 is provided with a handheld part 21 which facilitates the knob cap to rotate, the bottom of the knob cap 2 is provided with a clamping groove 22, and the protruding block 43 is inserted into the clamping groove 22.

The elastic clamping piece 6 comprises a square main frame 60, and the square main frame 60 is clamped above the electromagnetic device 5 so that the frame cannot rotate; the side of the square main frame 60 is provided with a mounting notch 63 connected with the supporting arm 61, and the mounting notch 63 is provided with a bolt and is tightly mounted in the shell by the bolt.

The top of the lock cylinder 4 is provided with a convex block 43, the convex block 43 is sleeved with a knob cap 2, and the knob cap 2 can drive the lock cylinder 4 to rotate.

The lock core 4 is connected with a lock head 7, a lock plate connecting part 73 is arranged at the bottom of the lock head 7, and various different lock plates can be installed on the lock plate connecting part 73 for locking.

The front surface of the shell is provided with a digital input board 11, and the digital input board 11 controls the work of the electromagnetic device 5.

A protruded rotating block 44 is arranged on one outer side wall of the lock cylinder 4, a plurality of spaced supporting blocks 33 are arranged in the rotating sleeve 3, and the rotating block 44 can be movably pressed on the supporting blocks 33; the top of the supporting block 33 of one block is provided with a limiting step 341, and the limiting step 341 can block the movement of the rotating block 44 so as to limit the maximum rotation amount thereof.

The spacing of the support blocks 33 is less than the width of the turning blocks 4.

The bottom of the lock cylinder 4 is provided with a square connecting raised head 45, the top of the lock head 7 is provided with a square locking groove 71, and the connecting raised head 45 is inserted into the locking groove 71 so as to limit the mutual rotation between the lock cylinder 4 and the lock head 7; the lock cylinder 4 is provided with a threaded hole 72, and the lock cylinder 4 is provided with the lock head 7 by means of threaded connection.

The elastic clamping piece 6 of the device is matched with the rotating sleeve 3, so that a user can be reminded when the locking and the unlocking of the knob cap 2 are started after the locking is finished. In particular, the support arms 61 have a certain elasticity, so that the two support arms 61 can be separated from each other by a certain distance. The fixture block 62 is clamped in the limiting clamping groove 32, and when the knob cap 2 is screwed to unlock, the rotating sleeve 3 rotates, so that the fixture block 62 is separated from the limiting clamping groove 32. During the period from the time before the detachment to the time when the detachment is completed, the latch 62 acts on the limit latch groove 32, and there is a force for limiting the screwing of the knob cap 2. The user can feel the acting force, and after the user twists the knob cap 2, the limitation in the acting force is broken, and obvious feedback effect can be felt. This feedback can alert the user. In addition, when the user twists the knob cap 2, the fixture block 62 is clamped into the limit clamp groove again, and a very obvious feedback effect can be sensed. Thus, the user can be reminded whether the lock is locked or unlocked.

The device has a battery and a circuit board in its housing, and a digital input board 11 is connected to the circuit board, which cooperate to control the electromagnetic device 5.

The device has two unlocking modes, one is to adopt a key, and the other is to adopt a digital password.

When the key is adopted, the key is inserted into the lock cylinder, and the lock cylinder can be rotated after the lock block is extruded, so that unlocking is completed. The locking blocks of the device have different structures, so that a special key is needed for extruding all the locking blocks simultaneously, and people do not need to worry about unlocking.

Another way to unlock requires the correct password to be entered on the numeric entry pad. When the input is correct, the electromagnetic device 5 is energized, so that the locking bar 51 is retracted and disengaged 31 from the stop groove 31, and the factor limiting the rotation of the sleeve 3 is eliminated. At this time, the knob cap 2 can be twisted by hand to rotate the key cylinder 4. At this time, the lock piece still snaps into the key cylinder 4 to restrict the mutual rotation of the two, but the two can rotate together, so that the unlocking can be completed.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive. The scope of the invention is indicated by the appended claims, rather than the foregoing description, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
