A compression spring push rod support surface 9.2 is provided on the inner wall of the push rod box 9 near the push rod box opening 9.1. A compression spring push rod 11 is provided inside the push rod box 9. A push rod box through hole is opened on the lower plate 4. The upper part of the push rod box 9 extends upward through the push rod box through hole. A compression spring push rod push block 12 that can move into and out of the push rod box opening 9.1 is installed on the lower plate 4. A cover plate is fixed on the track groove, and a locking push block assembly is slidably installed in the track groove. A solid fixed rectangular groove is provided on the inner wall of the rear shell corresponding to the pushing direction of the locking push block assembly. The lower end of the pressure cap 2 is hinged to the upper end of the spring push rod 11 by a pin. A push rod torsion spring is installed on the pin. One end of the push rod torsion spring is fixed to the spring push rod 11, and the other end of the push rod torsion spring is fixed to the pressure cap 2. A compression spring push rod through hole is provided on the upper plate 3. The compression spring push rod 11 passes through the compression spring push rod through hole and extends into the push rod box 9. A compression spring is provided between the pressure cover 2 and the upper plate 3, which is sleeved on the outside of the compression spring push rod 11. A connecting rod bracket 17 is provided on the front and rear sides of the stamp cylinder 7, and is fixed relative to the stamp cylinder 7. Two left connecting rods 18.1 and two right connecting rods 18.2 are hinged to the lower end of the connecting rod bracket 17. A left inkpad box bottom shell 19.1 is hinged to the lower left inner wall of the rear shell via a left pin. A left inkpad box is installed inside the left inkpad box bottom shell 19.1. A left inkpad is provided inside the left inkpad box. A left torsion spring is installed on the left pin. One end of the left torsion spring is fixed to the rear shell, and the other end of the left torsion spring is fixed to the left inkpad box bottom shell 19.1. A left oil filling hole that mates with the left inkpad box is opened on the left side wall of the rear shell above the left inkpad box bottom shell 19.1. A right inkpad box bottom shell 19.2 is hinged to the lower right inner wall of the rear shell via a right pin. A right inkpad box is installed inside the right inkpad box bottom shell 19.2, and right inkpad is provided inside the right inkpad box. The right inkpad and the left inkpad are overlapped. A right torsion spring is installed on the right pin. One end of the right torsion spring is fixed to the rear shell, and the other end of the right torsion spring is fixed to the right inkpad box bottom shell 19.2. A right oil filling hole that mates with the right inkpad box is opened on the right side wall of the rear shell above the right inkpad box bottom shell 19.2. The lower end of the left connecting rod 18.1 is hinged to the bottom shell 19.1 of the left inkpad box, and the lower end of the right connecting rod 18.2 is hinged to the bottom shell 19.2 of the right inkpad box.

[0016] A guide sleeve 15 is fixed on the lower plate 4, and a guide rod 16 is fixed on the hanging plate 5. The guide rod 16 includes an upper cylindrical section and a lower cylindrical section of the guide rod that are coaxially connected. The diameter of the upper cylindrical section of the guide rod is smaller than the diameter of the lower cylindrical section of the guide rod. The upper cylindrical section of the guide rod cooperates with the guide sleeve 15.

[0017] A suspension spring is installed on the lower surface of the upper plate 3, and the lower end of the suspension spring is connected to the hanging plate 5.

[0018] The locking push block assembly includes a first locking push block and a second locking push block hinged together.

[0019] In this invention, the torsion of the push rod torsion spring continuously pushes the compression spring push rod 11 towards the push rod box opening 9.1, with the lower end of the compression spring push rod 11 resting on the compression spring push rod support surface 9.2 of the push rod box 9. During normal use, the lock stamp push block assembly is in the retracted state. Pressing down on the pressure cover 2 causes the compression spring push rod 11 to move the push rod box 9, the hanging plate 5, and all components mounted on the hanging plate 5 downwards after overcoming the elastic force of the compression spring and the suspension spring. The stamp cylinder cover 6, the stamp cylinder 7, the stamp 8, and the connecting rod bracket 17 descend synchronously. The left and right inkpad bottom shells 19.1 and 19.2 are opened via the left connecting rod 18.1 and the right connecting rod 18.2. When the stamp 8 descends to the bottom, the left and right inkpad bottom shells 19.1 and 19.2 are opened. The bottom shell 19.2 has been fully opened and stamped. After stamping, the downward pressure is released, and the hanging plate 5 moves upward under the action of the suspension spring until it returns to its original position. The pressure cover 2 moves upward under the action of the pressure spring until it returns to its original position. At the same time, under the action of the left and right torsion springs, the bottom shells 19.1 and 19.2 of the left and right inkpad boxes gradually close until they completely block the stamp surface of the stamp 8, thus preventing rubbing and automatically applying oil to the stamp surface.

[0020] When the seal needs to be locked, the seal locking motor (not shown in the figure) is turned on, causing the seal locking motor to rotate forward. If the hanging plate 5 is in the initial position, the seal locking motor will push the first seal locking push block and the second seal locking push block towards the solid fixed rectangular groove until the second seal locking push block enters the solid fixed rectangular groove of the rear shell, thereby fixing the vertical linear freedom of the hanging plate 5, the seal cylinder cover 6, the seal cylinder 7, the seal 8 and the connecting rod bracket 17. The hanging plate 5, the seal cylinder cover 6, the seal cylinder 7, the seal 8 and the connecting rod bracket 17 cannot move downward, and the left inkpad bottom shell 19.1 and the right inkpad bottom shell 19.2 cannot be opened. The seal locking operation is completed, thus playing the role of preventing rubbing.

[0021] When the seal is needed, turn on the seal motor to make it rotate forward. If the mounting plate 5 is in the lowest position, the seal motor will push the first and second seal push blocks towards the solid fixed rectangular slot. The second seal push block cannot enter the solid fixed rectangular slot in the rear shell. Turn the seal motor in reverse to pull the first and second seal push blocks back to their initial positions, and then turn off the seal motor. Turn on the push rod push block motor (not shown in the figure). The push rod push block motor will push the spring push rod push block 12 towards the push rod box opening 9.1 until the spring push rod push block 12 pushes the spring push rod 11 to the side away from the push rod box opening 9.1. The spring push rod 11 is in an unloaded state. At this time, when the pressure cover 2 is pressed, the pressing force cannot be transmitted through the spring push rod 11. At this time, the rebound force of the suspension spring will return the mounting plate 5, the seal cylinder cover 6, the seal cylinder 7, the seal 8, and the connecting rod bracket 17 to their initial positions. Turning on the locking motor causes it to rotate forward, which in turn pushes the first and second locking push blocks towards the solid fixed rectangular groove. The second locking push block enters the solid fixed rectangular groove in the rear shell, thus fixing the vertical linear freedom of the hanging plate 5, the stamp cylinder cover 6, the stamp cylinder 7, the stamp 8, and the connecting rod bracket 17. The hanging plate 5, the stamp cylinder cover 6, the stamp cylinder 7, the stamp 8, and the connecting rod bracket 17 cannot descend, and the left and right inkpad bottom shells 19.1 and 19.2 cannot be opened. The locking operation is then complete, thus preventing rubbing.
