A first end of the connecting member is fixedly connected to the follower 220, and a second end of the connecting member is fixedly connected to the first end of the screw 210. Referring to fig. 3 and 5, the driven member 220 and the driving member 230 are friction wheels, the driven member contacts with the driving member, the driving member 230 rotates to drive the driven member 220 to rotate, and the driving member 230 rotates by a motor 240 installed in the inner cavity.

Referring to fig. 1, 3 and 5, the transfer mechanism includes an inner cylinder 310, a mount 320 and a transfer member 330. The first end of the inner cylinder 310 is fixedly arranged in the inner cavity by gluing and the like, and the second end of the inner cylinder 310 extends out of the shell 110; the outer wall of the inner cylinder 310 is fixedly connected to the inner wall of the outer shell 110 (and the wall of the first spiral groove 120). Referring to fig. 2 and 3, the inner cylinder 310 is provided with a push hole, the push hole is located at a portion of the inner cylinder extending out of the outer casing, and the push hole is located between the motion tracks of the adjacent spiral pieces 210, and when the second end of the spiral piece 210 rotates to the second end of the inner cylinder 310, the spiral piece 210 does not pass through the push hole. Referring to fig. 3 and 5, a positioning member 340 for positioning the mounting member 320 is provided inside the inner tube 310. In a preferred embodiment, the positioning element 340 is a positioning ring fixedly mounted on the inner wall of the inner barrel 310. The mounting member 320 is clamped inside the inner barrel 310, and a first end (close to the first end of the inner barrel 310) of the mounting member 320 abuts against the positioning member 340; the second end of the mounting member 320 (the second end near the inner cylinder 310) is fixedly attached to the transfer member 330 by means of gluing or the like. The clamping piece is provided with a breaking hole.

Referring to fig. 1, 3 and 5, the breaking mechanism includes a breaking member 410 and a pushing member 420. The breaking member 410 is inserted into the breaking hole, a first end of the breaking member 410 extends toward the first end of the inner cylinder 310, and a second end (close to the second end of the inner cylinder 310) of the breaking member 410 is fixedly provided with a sharp head to break the transfer member 330 when the breaking member 410 is pressed. The transfer member 330 cannot be broken by the weight of the breaking member 410 alone. In a preferred embodiment, a spacer is further disposed in the breaking hole, and the spacer is located between the breaking member 410 and the transfer member 330 to prevent the breaking member 410 from directly contacting the transfer member 330. The gasket may be made of cork or the like so that the breaking member 410 may penetrate the gasket when the breaking member 410 is pressed by the pushing member 420.

Referring to fig. 3 and 5, the push member 420 is inserted into the push hole. The pushing member 420 is fixedly installed with a stopper 421 for preventing the pushing member 420 from coming out of the inner cylinder 310 from the pushing hole. The first end of the pushing member 420 abuts against the first end of the breaking member 410, and the second end of the pushing member 420 protrudes out of the inner cylinder 310. When the pushing member 420 is pushed toward the destruction member 410, the destruction member 410 is pressed, and the transfer member 330 is destroyed. The first end of breaking element 410 is obliquely arranged, so that the side of the first end of breaking element 410 close to the pushing hole is lower than the side of the first end of breaking element 410 far away from the pushing hole; the first end of the pushing member 420 is disposed obliquely so that the side of the first end of the pushing member 420 remote from the transfer member 330 is remote from the pushing hole, and the side of the first end of the pushing member 420 close to the transfer member 330 is close to the pushing hole. So arranged, when the stamp is reversed, the pushing member 420 can block the destroying member 410 and prevent the destroying member 410 from falling out of the destroying hole.

Referring to fig. 1, 3 and 5, in a preferred embodiment, to further prevent displacement of the breaking member 410, the mounting member 320 is further fixedly mounted with a breaking cylinder 321 for receiving the breaking member 410, the breaking cylinder 321 extending toward the first end of the inner cylinder 310, the breaking cylinder 321 communicating with the breaking hole. In a preferred embodiment, to prevent the pushing member 420 from being deviated, the mounting member 320 is further fixedly mounted with a positioning portion 322, and the positioning portion 322 extends toward the first end of the inner tube 310. The positioning portion 322 is opened with a push groove for accommodating the push member 420. The side wall of the push groove is provided with a latch extending toward the inside of the push groove to prevent the push member 420 from falling out toward the first end of the inner cylinder 310. In a preferred embodiment, the latch has a triangular prism shape, so that the pushing member 420 is easily pressed into the pushing groove by an external force and is also easily pulled out of the pushing groove by an external force.

Referring to fig. 1, 3 and 5, the outer cover 510 is used to cover the transfer mechanism. The inner wall of the outer cap 510 is provided with a second screw groove 520 for screw-coupling with the screw 210. The pushing holes are located between the moving tracks of the adjacent screws 210, that is, the pushing holes are located on the spiral tracks of the groove walls of the second groove 520, when the outer cover 510 rotates, the groove walls of the second groove 520 pass through the pushing holes to push the pushing member 420, so that the pushing member 420 presses the breaker 410, and the breaker 410 breaks the transfer-printed member 330. The second end of the pushing member 420 is disposed obliquely, so that the groove wall of the second groove 520 pushes the pushing member 420. The groove wall of the second groove 520 is provided with an accommodating groove 530 for accommodating the pushing member 420, so that when the outer cover 510 is mounted or removed in a non-rotating state, the groove wall of the second groove 520 does not pass through the pushing hole to push the pushing member 420.

The identification mechanism comprises an identification device 610 and a control circuit (not shown in the figure), wherein the identification device 610, the control circuit and the motor 240 are connected, and the control circuit can control the motor 240 to rotate forward and backward. Referring to fig. 1 to 5, the recognition device 610 is fixedly installed at the housing 110, and the control circuit is installed at the inner cavity. The housing 110 is provided with a threading hole so that the recognition device 610 can be electrically connected to the control circuit through an electric wire. The threading hole is located under the recognition device 610, so that the recognition device 610 can shield the threading hole and prevent other people from applying forward rotation or reverse rotation signals from the threading hole. In a preferred embodiment, the identification device 610 is a fingerprint identification device. Referring to fig. 4 and 5, in use, when a finger presses the fingerprint identification device, and when fingerprints are matched, the motor 240 rotates forward, and the second end of the screw 210 rotates back to the inner cavity; referring to fig. 2 and 3, after the control circuit controls the motor to rotate forward, the motor is stopped for a period of time to wait for a user to stamp, and then the control circuit controls the motor 240 to rotate backward, so that the second end of the screw 210 is rotated to the second end of the inner cylinder 310. Since the fingerprint identification device and the control circuit control the forward rotation and the reverse rotation of the motor belong to the prior art (refer to the chinese patent CN102152671B), the details are not described.

The working principle is as follows: in assembly, the identification device 610 is mounted to the outer wall of the housing 110 and the control circuit and screw mechanism are mounted within the interior cavity. The first end of the inner cylinder 310 is inserted into the inner cavity, so that the pushing hole is located between the moving tracks of the adjacent spiral pieces 210, and then the outer wall of the first end of the inner cylinder 310 is fixedly connected with the inner wall of the outer shell 110 (also the groove wall of the first spiral groove 120) by means of gluing and the like. The pushing member 420 passes through the pushing hole, and the limit portion 421 abuts against the inner wall of the inner cylinder 310. The transfer member 330 is fixed to the mounting member 320 by means of adhesive or the like, and the destruction member 410 is placed after the spacer is placed in the destruction hole. The mounting member 320 is engaged with the inner cylinder 310 from the bottom to the top, the pushing member 420 is pressed into the pushing groove, and the first end of the breaking member 410 is in contact with the first end of the pushing member 420. The second end of the screw element 210 is screwed into the inner cavity to align with the receiving groove 530 on the outer cover 510 and the portion of the pushing element 420 extending out of the inner cylinder 310, so as to prevent the groove wall of the second groove 520 from pushing the pushing element 420. The outer cap 510 is threaded onto the inner barrel 310 and the screw 210 is threaded onto the inner barrel 310 at the second end.

When the fingerprint identification device is used, the fingerprint identification device is pressed by fingers, the motor does not rotate when the fingerprints are not matched, the motor 240 rotates forwards when the fingerprints are matched, the second end of the spiral piece 210 rotates back to the inner cavity, and at the moment, the outer cover 510 can be directly (non-rotatably) taken down and sealed by the transfer piece 330. After the sealing, the holding groove 530 on the outer lid 510 and the portion of the pushing element 420 extending out of the inner cylinder 310 are aligned to prevent the groove wall of the second screw groove 520 from pushing the pushing element 420, so as to buckle the outer lid 510 on the inner cylinder 310, and the motor 240 rotates reversely to rotate the second end of the screw element 210 to the second end of the inner cylinder 310, so that the outer lid is in threaded connection with the screw element.

If someone tries to take off the outer cover by directly pulling off the outer cover, the outer cover cannot be pulled off due to the matching of the second screw groove and the screw part; when the outer cover 510 is removed by rotation, the pushing member 420 is pushed by the groove wall of the second groove 520, and the pushing member 420 presses the breaking member 410, so that the breaking member 410 penetrates through the gasket to break the transfer member 330, thereby preventing the transfer member from being stolen by others. When the seal is required to be overhauled, the outer cover 510 is taken down firstly, and the mounting part 320 is pried down, so that the seal can be overhauled. Therefore, the safety of the seal can be improved.

It is to be understood that: although the present invention has been described in some detail by way of the specific embodiments, these descriptions are not intended to limit the scope of the invention, and any changes in form and detail that do not exceed the scope of the claims are intended to fall within the scope of the invention.
