[0031] The pressing assembly 4 includes a pressure cover 401, a push rod 402, a hanging plate 403, and a push rod box 404;

[0032] The lower end of the pressure cap 401 is hinged to the upper end of the push rod 402. A hanging plate 403 is provided below the pressure cap 401. A push rod box 404 is fixed on the upper surface of the hanging plate 403, and a push block is slidably installed on the upper surface of the hanging plate 403. The lower end of the push rod 402 cooperates with the push rod box 404, and the push block cooperates with the push rod 402. When the pressure cap 401 is pressed down, the downward pressure is transmitted to the push rod box 404 through the push rod 402, and finally to the hanging plate 403, causing the hanging plate 403 to move downward against the elastic force of the hanging plate return spring. When the downward pressure is removed, the push block pushes the push rod 402, causing the push rod 402 to separate from the push rod box 404. Under the elastic force of the hanging plate return spring, the hanging plate 403 moves upward to its initial state.

[0033] The lock assembly 3 includes a lock box 301, a lock cover, a lock head base, and a lock head 302;

[0034] The lock box 301 is fixed to the lower right side of the inner side of the outer shell 101. The top of the lock box 301 is provided with a lock tongue notch. A lock cover is installed at the left end of the lock box 301. A lock head hole is opened on the lock cover. A lock head seat and a lock head seat return spring are slidably installed inside the lock box 301. A lock head 302 is provided on the left side of the lock head seat. The left end of the lock head 302 protrudes from the lock head hole on the lock cover. The lock head 302 is matched with the lock head groove on the ink ink holder 201. A lock head seat inclined surface is provided on the lock head seat located in the lock tongue notch.

[0035] The unlocking component 5 includes a latch rod 501 and a latch 502; the upper end of the latch rod 501 is fixed to the hanging plate 403, and a latch 502 is provided at the lower end of the latch rod 501. A lock head seat driving inclined surface 503 is provided on the latch 502, and the lock head seat driving inclined surface 503 on the latch 502 cooperates with the lock head seat inclined surface on the lock head seat.

[0036] The ink printing bracket assembly 2 also includes two optical axes 203. One optical axis 203 is fixed on the inner side and the other on the outer side of the ink printing bracket 201, and the two optical axes 203 are arranged in parallel.

[0037] The connecting rod assembly 6 includes a main connecting rod 601 and a secondary connecting rod 602. The upper end of the main connecting rod 601 is fixed to the hanging plate 403. A main connecting rod elongated hole is provided at the lower end of the main connecting rod 601. A main connecting rod slot is provided at the upper end of the secondary connecting rod 602. Secondary connecting rod round holes are provided on the secondary connecting rods 602 on both sides of the main connecting rod slot. The lower end of the main connecting rod 601 is inserted into the main connecting rod slot, and a connecting pin is installed in the secondary connecting rod round hole and the main connecting rod elongated hole. The connecting pin hinges the main connecting rod 601 and the secondary connecting rod 602 together. A light axis mounting hole 603 is provided at the lower end of the secondary connecting rod 602. The secondary connecting rod 602 is sleeved on the corresponding light axis 203 through the light axis mounting hole 603. The secondary connecting rod 602 can slide flexibly along the light axis 203.

[0038] When a stamp is needed, the stamp 8 should first be horizontally inserted into the stamp container 7 using a clamp. By adjusting the height, the stamp 8 can extend a certain distance out of the stamp container 7, which will ensure that the initial position of the stamp 8 has a certain gap with the printing cotton 202. Then, the stamp barrel 7 is inserted into the hanging plate 403 of the pressing component 4. When the downward pressure is applied to the upper end face of the pressure cap 401, the downward pressure is transmitted to the push rod box 404 and the hanging plate 403 through the push rod 402, causing the hanging plate 403 to move downward against the elastic force of the hanging plate return spring. When the hanging plate 403 moves downward, it drives the unlocking component 5, the connecting rod component 6, the stamp barrel 7 and the stamp 8 to move downward together. The main connecting rod 601 can move downward along the connecting pin. Since the lock head component 3 is fixed at the lower right end of the inner side of the outer shell 101, the lock head 302 in the lock head component 3 is kept in the extended state under the spring force of the lock head seat return spring. During the distance from when the stamp 8 moves downward to when it fully contacts the printing cotton 202, the ink support 201 is kept horizontal under the action of the lock head 302. After the stamp 8 moves downward a certain distance, it can fully contact the printing cotton 202 and apply ink.

[0039] Once the stamp 8 has fully contacted the ink cotton 202 and adhered to the ink, the pressing component 4 continues to move downwards. The locking head seat driving inclined surface 503 on the locking tongue 502 contacts the locking head seat inclined surface on the locking head seat and drives the locking head seat to move to the right until the locking head 302 exits from the locking head slot of the ink holder 201. The pressing component 4 drives the main connecting rod 601 to push the secondary connecting rod 602 to move along the optical axis 203. The ink holder 201 can be opened around the ink holder pin, and the stamp 8 continues to extend to complete the stamping action. The stamping effect is complete and clear.

[0040] After the stamping is completed, the downward pressure acting on the upper surface of the pressure cap 401 is removed. The push block motor drives the push block forward, and the push block pushes the push rod 402, causing the push rod 402 to separate from the push rod box 404. Under the elastic force of the hanging plate reset spring, the hanging plate 403, the unlocking component 5, the connecting rod component 6, the stamp barrel 7, and the stamp 8 move upward together and return to the initial state.

[0041] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
