[0023] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0024] like Figures 1 to 2 As shown, a printing bed support with both height and angle adjustment includes a lifting seat 10, an adjusting seat 20 and a positioning seat 30. The lifting seat 10 includes a base 11, a first scissors bracket 12 and a second scissors bracket 13. The first scissors bracket 12 is arranged on the base 11, and the second scissors bracket 13 is hinged to the upper end of the first scissors bracket 12, and an adjusting member 14 is provided between the two for adjusting the height of the two. The adjusting seat 20 includes a positioning platform 21 and a supporting assembly 22. One end of the positioning platform 21 is hinged to one side of the second scissors bracket 13, one end of the supporting assembly 22 is hinged to the other side of the second scissors bracket 13, and the other end of the supporting assembly 22 is arranged in the adjusting slot 2101 of the positioning platform 21 for adjusting the inclination angle of the positioning platform 21. The positioning seat 30 is arranged at the upper end of the positioning platform 21 for connecting the printing bed 100.

[0025] In the present invention, the printing bed 100 is fixed on the positioning seat 30. When in use, the adjustment member 14 can be driven to make the connection between the second scissors bracket 13 and the first scissors bracket 12 relatively rotate closer or farther, so that the second scissors bracket 13 and the first scissors bracket 12 can be lifted and lowered respectively, so that the lifting seat 10 drives the adjustment seat 20 and the positioning seat 30 located on the adjustment seat 20 to be lifted and lowered, so as to adjust the height of the printing bed 100. Moreover, by adjusting the support assembly 22 to different positions in the adjustment slot 2101 on the positioning platform 21, the inclination angle of the printing bed 100 can be adjusted. The above-mentioned adjustment of the printing bed height and inclination angle allows the seal engraver to perform seal engraving in a more relaxed state.

[0026] More specifically, the specific structure of the positioning platform 21 includes a positioning plate 211, and a clamping plate 212 disposed at the lower end of the positioning plate 211, the clamping plate 212 is provided with a plurality of clamping grooves for forming the adjustment groove 2101, one end of the support assembly 22 away from the second scissor bracket 13 is embedded in the clamping groove, and the positioning seat 30 is disposed on the positioning plate 211. In the present utility model, there are two positioning plates 211 and two clamping plates 212, and one positioning plate 211 and one clamping plate 212 are an integral structure, and the two are formed by bending into a vertical clamping plate 212 for forming the adjustment groove 2101 thereon, and the horizontal positioning plate 211 is formed for fixed connection with the positioning seat 30.

[0027] In addition, the lower end of the card plate 212 has a sealing plate, and a slide groove 2102 connected to the card slot is formed between the sealing plate and the card slot, that is, the adjustment slot 2101 is connected to the slide groove 2102 but not to the outside. The end of the support component 22 is located at different positions in the adjustment slot 2101 by being embedded in different card slots after moving in the slide groove 2102. The setting of the above-mentioned closed structure can prevent the support component 22 from detaching from the card plate 212 and maintain the stability of the connection.

[0028] The number of the card slots is two to six, and preferably, each card plate 212 is provided with three card slots, that is, the adjustment slot 2101 on each card plate 212 has three card connection positions, which can realize the support of the fixed printing bed 100 at three angles.

[0029] The support assembly 22 includes a support rod 221 and a clamping column 222. Since there are two clamping plates 212, one end of a pair of support rods 221 is hinged to the two sides of the second scissors bracket 13, and the other end is provided with a clamping column 222. The clamping column 222 is embedded in the clamping groove (adjusting groove 2101) to support the positioning platform 21. By rotating the support rod 221, the clamping column 222 can be adjusted to be positioned in the clamping groove at different positions. The clamping column 222 is preferably a bolt locked on the support rod 221; in addition, a plurality of different hole positions can be set on the support rod 221 to realize different installation positions of the clamping column 222 (bolt), which can also be conducive to realizing different support angles.

[0030] Preferably, the support assembly 22 also includes a connecting rod (not shown), the two ends of which are respectively connected to a pair of support rods 221 or clamping columns 222. The connection between the pair of support rods 221 can be achieved through the fixing effect of the connecting rod, which can ensure the synchronization and consistency of the pair of support rods 221 during adjustment, and avoid the clamping columns located on different support rods from being embedded in two non-opposite slots on a pair of clamping plates 212, that is, avoid the lateral tilt of the positioning seat 30 and the printing bed 100.

[0031] The adjusting member 14 includes a cross bar 141 and a screw 142. A pair of cross bars 141 are respectively arranged at the connection between the first scissors bracket 12 and the second scissors bracket 13. The screw 142 passes through the openings on the pair of cross bars 141 and adjusts the distance between the pair of cross bars 141 through the screw connection structure with the openings. The distance between the pair of cross bars 141 is changed by rotating the screw 142, so that the connection between the second scissors bracket 13 and the first scissors bracket 12 can be relatively rotated closer or farther, so as to change the height of the second scissors bracket 13 and the first scissors bracket 12. The screw connection structure can be relatively stable without rotating the screw 142, and can withstand the downward pressure applied by the seal engraver to ensure the height stability of the lifting seat 10. In addition, the adjusting member 14 also includes a screw cap 143, which is fixed to the end of the screw 142. The setting of the screw cap 143 facilitates the rotation of the screw 142.

[0032] In order to ensure that the first scissors bracket 12 can work normally, the base 11 specifically includes a bottom plate 111 and a limiting plate 112 arranged on the upper end of the bottom plate 111, and the limiting plate 112 is provided with a limiting groove 110. One side of the first scissors bracket 12 is hinged to one side of the limiting plate 112 or the bottom plate 111, and the other side is slidably arranged in the limiting groove 110. The arrangement of the above structure can ensure that the first scissors bracket 12 can be lifted and lowered; the first scissors bracket 12 can be embedded in the limiting groove 110 by a bolt arranged at its lower end.

[0033] Preferably, the limiting groove 110 is a closed structure, that is, one end of the first scissors bracket 12 is positioned in the limiting groove 110 and cannot be separated, which can ensure the connection stability between the first scissors bracket 12 and the base plate.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
