Furthermore, the hook assembly has an upward retracted state in which it moves upward in the vertical direction to the upper end of the upward movement, and a downward pull-down state in which it moves downward in the vertical direction to the lower end of the downward movement. When the hook assembly is in the upward retracted state, the stamp pattern surface of the stamp body is in contact with the ink in the ink cartridge carried by the tray in the horizontally placed state. And when the hook assembly is in the downward pull-down state, the stamp pattern surface of the stamp body is de-contacted or the contact with the ink in the ink cartridge carried by the tray in the horizontally placed state is reduced or eliminated.

The flipping shaft 13 and the tray 21 are connected to each other to drive the tray to make a flipping switching motion.

[0054] Referring to Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, the hook assembly comprises an assembly housing 120, a first latch 121, a first elastic member 12a, a second latch 122, a second elastic member 12b and a push rod 123, the assembly housing 120 is assembled at the lower end of the ink box hanger body 11 and can generate back and forth movement towards or away from the ink box hanger body 11; the first latch 121, the first elastic member 12a, the second latch 122, the second elastic member 12b and the push rod 123 are all arranged on the ink box hanger body 11; the first latch 121 is configured to be able to be clamped into and moved out of the preset upper clamping groove 111 of the ink box hanger body 11; the first elastic member 12a is configured to generate a reset movement to form a driving force to drive the first latch 121 to move out of the preset upper clamping groove 111; the second latch 122 is located below the first latch 121, and the second latch 122 is configured to be clamped into and moved out of the preset lower clamping groove 112 of the ink box hanger body 11; the second elastic member 12b is configured to generate a reset movement to form a driving force to drive the second latch 122 to move out of the preset lower clamping groove 112; the push rod 123 is configured to have a first extrusion part 1231 for extruding the first latch 121 clamped into the preset upper clamping groove 111 and a second extrusion part 1232 for extruding the second latch 122 clamped into the preset lower clamping groove 112; wherein the extrusion state of the first extrusion part on the first latch and the extrusion state of the second extrusion part on the second latch are non-simultaneous state. And when the first latch 121 is clamped into the preset upper clamping groove 111 of the ink box hanger body 11, the second latch 122 is moved out of the preset lower clamping groove 112, and the hook assembly is in a pulled-down state; correspondingly, when the second latch 122 is clamped into the preset lower clamping groove 112 of the ink box hanger body 11, the first latch 121 is moved out of the preset upper clamping groove 111, and the hook assembly is in an up-retracted state.

[0055] As to the specific structure of the push rod, in this embodiment, the push rod 123 comprises a rod body 1230, the first extrusion part 1231 and the second extrusion part 1232, the rod body 1230 is configured to be arranged on the ink box hanger body 11 and can move up and down along the vertical direction under force; the first extrusion part 1231 is located at the upper part of the rod body 1230, and has a first pointed end part 12311 for extruding the first pin 121; the second extrusion part 1232 is located at the lower side of the first extrusion part 1231, and has a second pointed end part 12321 for extruding the second pin 122. By extruding the first pin 121 by the first pointed end part 12311 of the first extrusion part, the first pin can be clamped into the preset upper clamping groove 111 of the ink box hanger body; by extruding the second pin 122 by the second pointed end part 12321 of the second extrusion part, the second pin can be clamped into the preset lower clamping groove 112 of the ink box hanger body.

[0056] As a preferred arrangement of the hook assembly, in this embodiment, the hook assembly has two first pins 121 and two second pins 122, the two first pins 121 are symmetrically distributed, and a first gap 1210 is formed between the two first pins 121 for the first pointed end part of the first extrusion part 1231 to extrude into; a second gap 1220 is formed between the two second pins 122 for the second pointed end part of the second extrusion part to extrude into; the first elastic member 12a is elastically connected with the corresponding first pin 121, and the second elastic member 12b is elastically connected with the corresponding second pin 122. When the first pointed end part extrudes into the first gap, the second pointed end part moves out of the second gap; when the second pointed end part extrudes into the second gap, the first pointed end part moves out of the first gap.

[0057] Specifically, referring to Figure 8 In this embodiment, the first pointed end part 12311 of the first extrusion part is V-shaped with the pointed end facing the second pointed end part, and the second pointed end part 12321 of the second extrusion part is V-shaped with the pointed end facing the first pointed end part.

[0058] In order to make the assembly shell of the hook assembly fit the insertion operation of each pin into the corresponding preset buckle slot, and to make the assembly shell stably in the up-retracted state or the down-pulled state, in this embodiment, the assembly shell 120 is provided with a buckle part 1201 configured to be clamped by the first pin 121 inserted into the preset upper buckle slot or the second pin 122 inserted into the preset lower buckle slot. In this embodiment, the buckle part 1201 forms a gap below it for the second pin 122 to extend into to clamp the buckle part as the assembly shell 120 moves upward, and the buckle part 1201 forms a gap above it for the first pin 121 to extend into to clamp the buckle part as the assembly shell 120 moves downward. In this way, when the first pin 121 is inserted into the preset upper buckle slot, the hook assembly is in the down-pulled state, and the first pin 121 clamps the buckle part 1201 so that the buckle part 1201 cannot move upward, thereby making the hook assembly stably in the down-pulled state; when the second pin 122 is inserted into the preset lower buckle slot, the hook assembly is in the up-retracted state, and the second pin 122 clamps the buckle part 1201 so that the buckle part 1201 cannot move downward, thereby making the hook assembly stably in the up-retracted state.

[0059] According to actual needs, a through hole 1200 for the back-and-forth movement of the rod body of the push rod can also be provided at the bottom of the assembly shell.

[0060] In this embodiment, the working principle of the ink pad box turnover mechanism is described as follows:

[0061] By pushing the push rod to move upward, the second pointed end part is extruded into the second gap, and the first pointed end part is moved out of the first gap, so that the first pointed end part no longer extrudes the two first pins, and the second pointed end part extrudes the two second pins to be inserted into the corresponding preset lower buckle slots of the ink pad hanger main body, and the second elastic member is compressed due to the movement of the second pin connected thereto. Then, the first elastic member that was compressed generates an elastic return movement, and the first elastic member drives the first pin to move out of the preset upper buckle slot of the ink pad hanger main body. In this way, because the second pin is inserted into the corresponding preset lower buckle slot, the second pin 122 clamps the buckle part 1201 so that the buckle part 1201 cannot move downward, and the hook assembly is in a stable up-retracted state. The turnover shaft of the ink pad box turnover mechanism drives the ink pad box to turn over to a horizontal placement state, and the ink pad carrier carrying the seal body is also reset, so that the seal pattern surface of the seal body is in contact with the ink in the ink pad, and the seal pattern surface is inked.

[0062] By pulling the push rod downwards, the first tip is squeezed into the first gap, while the second tip moves out of the second gap. The second tip no longer presses against the second pins on both sides. The first tip presses against the first pins on both sides and inserts them into the preset upper snap-fit ​​slots of the corresponding ink cartridge holder body. The first elastic element is compressed due to the movement of the first pin connected to it. Subsequently, the originally compressed second elastic element undergoes an elastic reset movement, driving the second pin to move out of the preset lower snap-fit ​​slot of the ink cartridge holder body. Thus, because the first pin is inserted into the corresponding preset upper snap-fit ​​slot, the first pin 121 locks the snap-fit ​​part 1201, preventing the snap-fit ​​part 1201 from moving upwards. At this time, the hook assembly is in a stable downward pull-down state, thereby releasing the stamp pattern surface of the stamp body from contact with the ink in the ink cartridge, and the stamp pattern surface can no longer adhere to the ink.

[0063] As a structural method for cooperating with the ink cartridge to achieve its flipping, in this embodiment, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 7 As shown, the tray 21 carrying the ink cartridge has a flip track 20, which has an inclined section 201 and a track section 202 connected to the inclined section 201 and having a vertically extending trend. The flip shaft 13 is configured to be mounted on the stamp holder inside the stamping device. The cross-section of the flip shaft 13 is an ellipse with a side cut edge 13L, which is parallel to the track section 202. The side cut edge 13L is configured to fit against the track section 202 of the flip track 20.

[0064] In addition, this embodiment also provides a stamping device that utilizes the aforementioned ink cartridge flipping mechanism. Specifically, the stamping device includes a device housing and a stamp carrier, with the stamp carrier disposed within the device housing.

[0065] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
