Referring to fig. 1, 3 and 5, a stamp mechanism includes a housing 110, a screw mechanism, a transfer mechanism, an outer cover 510, and an identification mechanism.

Referring to fig. 3 and 5, a first screw groove 120 is formed on an inner wall of the housing 110. The housing 110 encloses an interior cavity.

Referring to fig. 1, 3 and 5, the screw mechanism includes a motor 240, a screw 210 spirally coupled to the first screw groove 120, a driven member 220 located at a shaft center of the screw 210, a coupling member for coupling the screw 210 and the driven member 220, and a driving member 230 for driving the driven member 220 to rotate. 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 220 is in contact with the driving member 230, 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. 1 to 5, the inner cylinder 310 is fixedly provided with a limiting member 350, the limiting member 350 extends toward the outside of the inner cylinder 310, the limiting member 350 is located at a portion of the inner cylinder 310 extending out of the outer shell 110, and the limiting member 350 is located between adjacent movement tracks of the screw element 210, so that when the second end of the screw element 210 rotates to move to the second end of the inner cylinder 310, the screw element 210 does not pass through the limiting member 350. 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.

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 position-limiting member 350 is located between the adjacent moving tracks of the screw 210, that is, the position-limiting member 350 is located on the screw track of the groove wall of the second screw groove 520, and the position-limiting member 350 can prevent the groove wall of the second screw groove 520 from rotating when the outer cover 510 is screwed out, so as to prevent others from screwing off the outer cover 510. The groove wall of the second screw groove 520 is provided with an accommodating groove 530 for accommodating the limiting member 350, so that when the outer cover 510 is mounted or removed in a non-rotating state, the groove wall of the second screw groove 520 is not blocked by the limiting member 350, thereby preventing the outer cover 510 from being mounted or removed.

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 240 to rotate forward, the machine will stop for a period of time, wait for the user to stamp, and then control 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 recognition device and the control circuit control the forward rotation and the reverse rotation of the motor 240 belong to the prior art (refer to chinese patent CN102152671B), they are not described in detail.

The working principle is as follows: when the fingerprint identification device is used, the fingerprint identification device is pressed by a finger, the motor 240 does not rotate when the fingerprints are not matched, the motor 240 rotates forwards when the fingerprints are matched, and the second end of the spiral piece 210 rotates back to the inner cavity. At this point, the cover 510 is removed straight (without rotation) and sealed with the transfer 330. After the sealing process, the outer cap 510 is fastened to the inner cylinder 310 by aligning the receiving groove 530 and the position-limiting member 350 on the outer cap 510, 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 cap 510 is screwed to the screw element 210.

If someone tries to remove the outer cap 510 by directly pulling out the outer cap 510, the outer cap 510 cannot be pulled out due to the cooperation of the second screw groove 520 and the screw 210; if the outer cap 510 is attempted to be removed by rotation, the movement of the groove wall of the second screw groove 520 is blocked by the limiting member 350, and the outer cap 510 cannot be rotated down. When needing to overhaul the inside seal, also need take off enclosing cover 510 earlier, prize the installed part 320, just can overhaul the inside seal. 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.
