[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figures 1 to 3 As shown, a printing press support with multiple adjustment functions includes a lifting base 10 and an angle adjustment assembly 20. The angle adjustment assembly 20 includes an upper side plate 21, a top plate 22, a first crossbar 23, a second crossbar 24, a first threaded rod 25, and a rotating rod 26. A pair of upper side plates 21 are symmetrically arranged on the upper end of the lifting base 10, and symmetrically provided with sliding grooves 201 on both. One end of the top plate 22 is hinged to the lifting base 10. The first crossbar 23 is arranged on the upper side plate 21. Preferably, the first crossbar 23 is fixed and will not rotate or translate relative to the upper side plate 21. The second crossbar 24 is slidably arranged in the sliding groove 201. The first threaded rod 25 rotatably passes through the first crossbar 23 and the second crossbar 24, and is threadedly connected to at least one of them. Rotation causes the first crossbar 23 and the second crossbar 24 to move closer to each other or further away from each other. A pair of rotating rods 26 are rotatably sleeved on both ends of the second crossbar 24, and the other end is respectively hinged to the top plate 22.

[0025] In this invention, the printing bed 30 is fixed to the top plate 22 of the angle adjustment assembly 20. When it is necessary to adjust the height or angle of the printing bed 30 during use, the height can be adjusted by adjusting the lifting base 10 to drive the angle adjustment assembly 20 and the printing bed 30 to move up and down. Rotating the first threaded rod 25 can drive the second crossbar 24 to move within the slide groove 201, causing the second crossbar 24 to move closer to or away from the first crossbar 23. Since one end of the top plate 22 is hinged to the lifting base 10 and the other end is hinged to the rotating rod 26, and the rotating rod 26 is rotatably mounted on the second crossbar 24, the movement of the second crossbar 24 will cause a change in the tilt angle of the rotating rod 26. For example, when the second crossbar 24 moves closer to the first crossbar 23, the rotation... The lower end of the rotating rod 26 moves closer to the first crossbar 23, causing the rotating rod 26 to gradually tend towards an upright state, thus raising one end of the top plate 22 and causing the top plate 22 to tilt at a large angle. When the second crossbar 24 moves away from the first crossbar 23, the lower end of the rotating rod 26 moves away from the first crossbar 23, causing the rotating rod 26 to gradually tend towards a horizontal state, thus lowering one end of the top plate 22 and making the tilt angle of the top plate 22 smaller. Furthermore, due to the screwing effect of the first threaded rod 25, the first crossbar 23 and the second crossbar 24 can be positioned. That is, when the first threaded rod 25 is rotated without external force, the positions of the first crossbar 23 and the second crossbar 24 on the first threaded rod 25 remain unchanged, which can ensure the tilt angle of the rotating rod 26 to ensure the tilt angle of the top plate 22.

[0026] This utility model allows the height of the angle adjustment component 20 located on the lifting base 10 to be adjusted by operating the lifting base 10. The angle adjustment component 20 can be used to adjust the angle of the top plate 22 and the printing bed 30 located on the top plate 22, thereby achieving multi-functional adjustment of height and angle, making it convenient for seal engravers to adjust to a suitable height and angle.

[0027] It should be noted that the movement of the second crossbar 24 relative to the first crossbar 23 can be configured in several ways: one way is as follows Figure 2 The and shown Figure 3As shown, the first threaded rod 25 has two threaded structures. The first threaded rod 25 is screwed to the first crossbar 23 and the second crossbar 24 through the threaded structures. Since the position of the first crossbar 23 is fixed, the first threaded rod 25 will move relative to the first crossbar 23 when it rotates. When the first threaded rod 25 moves, it will drive the second crossbar 24 to move relative to the first crossbar through the screwed connection with the second crossbar 24. Of course, the screwed connection between the first threaded rod 25 and the second crossbar 24 will also have the tendency and action to drive the second crossbar 24 to move relative to the first threaded rod. Another method is that the first threaded rod 25 has one threaded structure, which is screwed to the second crossbar 24. One end of the first threaded rod 25 is rotatably set on the first crossbar 23. When the first threaded rod 25 is rotated, the relative position of the first threaded rod 25 and the first crossbar 23 remains unchanged. The second crossbar 24 is driven to move relative to the first crossbar only through the screwed connection between the first threaded rod 25 and the second crossbar 24. The way the second crossbar 24 moves relative to the first crossbar 23 is not limited to the two methods mentioned above; other forms may also be used.

[0028] Regarding the specific form of the groove 201, such as Figure 3 As shown, in one embodiment, the slide 201 is provided with a sealing plate 211 that matches its length. The end of the slide 201 away from the first crossbar 23 has an open structure. The restriction of the slide 201 on the second crossbar 24 can prevent the second crossbar 24 from shifting upward or downward. The restriction of the sealing plate 211 on the second crossbar 24 can prevent the second crossbar 24 from moving along its axial direction, so that the second crossbar 24 can only translate within the slide 201, ensuring the stability of the translation of the second crossbar 24.

[0029] like Figure 4 As shown, in another embodiment, the slide groove 201 has an oblong hole structure, and limiting plates 241 are respectively provided at both ends of the second crossbar 24. Similarly, the oblong hole structure of the slide groove 201 can prevent the second crossbar 24 from shifting upward or downward, and a pair of limiting plates 241 located at the ends can prevent the second crossbar 24 from moving along its axial direction. Furthermore, a limiting ring 242 is provided on the second crossbar 24 on the opposite inner side of the rotating rod 26. The limiting ring 242 can ensure the stability of the position of the rotating rod 26 on the second crossbar 24.

[0030] Preferably, the upper end of the lifting base 10 is provided with a first connecting piece 10a, and the lower end of the top plate 22 is provided with a second connecting piece 20a. The first connecting piece 10a and the second connecting piece 20a are hinged together to hinge the top plate 22 to the lifting base 10.

[0031] Similarly, the lower end of the top plate 22 is provided with a third connecting piece 20b, which is hinged to the upper part of the rotating rod 26. If the third connecting piece 20b is provided with a first insertion hole, and the upper part of the rotating rod 26 is provided with a first insertion hole, the rotating rod 26 and the third connecting piece 20b are hinged together by a pin passing through the first insertion hole and the second insertion hole.

[0032] To facilitate the rotation of the first threaded rod 25, a first knob 251 can be provided at the end of the first threaded rod 25 away from the first crossbar 23.

[0033] like Figure 5 As shown, the lifting base 10 in this utility model is a scissor-type lifting platform. Its specific structure includes a base plate 11, a bearing plate 12, a first lower side plate 13, a second lower side plate 14, a first cross bracket 15, a second cross bracket 16, a third crossbar 17, and a second threaded rod 18. A pair of first lower side plates 13 are mounted on the base plate 11. One side of the lower end of the first cross bracket 15 is hinged to the first lower side plate 13, and the other side of its lower end is horizontally slidably mounted within the first guide groove 130 on the first lower side plate 13. A pair of second lower side plates 14 are mounted on... At the lower end of the bearing plate 12, one side of the upper end of the second cross bracket 16 is hinged to the second lower side plate 14, and the other side of its lower end is horizontally slidably disposed in the second guide groove 140 on the second lower side plate 14. The upper two sides of the first cross bracket 15 are respectively hinged to the lower two sides of the second cross bracket 16, and a third cross bar 17 is provided at each of the two hinge positions. The second threaded rod 18 can rotatably pass through a pair of third cross bars 17 and is threadedly connected to at least one of them, and the pair of third cross bars 17 are driven to move closer or further apart by rotation. When the second threaded rod 18 is rotated so that the pair of third crossbars 17 move closer to each other, the first cross bracket 15 and the second cross bracket 16 extend in the vertical direction, and the bearing plate 12 moves upward so that the lifting base 10 drives the angle adjustment component 20 to rise. When the second threaded rod 18 is rotated so that the pair of third crossbars 17 move away from each other, the first cross bracket 15 and the second cross bracket 16 shorten in the vertical direction, and the bearing plate 12 moves downward so that the lifting base 10 drives the angle adjustment component 20 to fall. Thus, the lifting action of the lifting base 10 is completed by rotating the second threaded rod 18. The connection method of the second threaded rod 18 and the pair of third crossbars 17 is the same as the connection method of the first threaded rod 25, the first crossbar 23 and the second crossbar 24. Preferably, the second threaded rod 18 can be screwed to one of the third crossbars 17, and can only be rotatably set in the other third crossbar 17. Therefore, when the second threaded rod 18 is rotated, since the second threaded rod 18 cannot be translated, the third crossbar 17 screwed to it is translated, thereby adjusting the distance between the pair of third crossbars 17. Moreover, due to the screw connection, when the second threaded rod 18 is rotated without external force, it will not rotate on its own, thus maintaining the distance between the pair of third crossbars 17.

[0034] Similarly, to facilitate the rotation of the second threaded rod 18, a second knob 181 can be provided at the end of the second threaded rod 18.
