Preferably, combined with Figure 2 and Figure 3 As shown, the tabletop bracket 5 covers most of the opening at the top of the movable housing 17, leaving a passage 171 through which the push rod of the power supply push rod 57 passes. The passage 171 is covered by the brush row 16 installed on the movable housing 17. The push rod of the electric push rod 57 passes through the brush row 16, which maintains the aesthetics and enhances the dustproof function.

[0026] Preferably, the push rod controller 53, the lifting column controller 54 and the cabinet power supply PDU 58 are respectively mounted on the fixed bracket 52.

[0027] The electric push rod is extended and retracted by the push rod hand controller, which drives the flipping table to rotate around the hinge point. The electric push rod has a self-locking function to ensure that the position remains unchanged after power is cut off.

[0028] Preferably, each side box 1 has a side box base 11 with a caster wheel 12 installed at the bottom, which allows the calligraphy table to be moved easily as a whole.

[0029] Furthermore, the flip tabletop 3 is made of two pieces of 27mm particleboard joined together; a ruler is attached to the front edge of the flip tabletop 3 facing the user, which can be used to determine the paper size.

[0030] The fixed tabletop 4 is made of two pieces of 27mm particleboard joined together.

[0031] Preferably, tools such as brush holders, inkstones and brush rests can be placed on the right fixed platform 4; a lifting column hand controller 41 and a push rod hand controller 42 are installed under the right fixed platform 4, which can realize one-button lifting and flipping.

[0032] Furthermore, it is also equipped with a magnetic paperweight 6, which has a permanent magnet that can maintain magnetic attraction for a long time. The magnetic paperweight 6 is attached to the flipping table 3, which can make the paper firmly fixed and not slip even on the tilted table.

[0033] Preferably, a paper feeding and cutting mechanism 2 can also be fixedly installed on the fixed platform 4 on the left side, which can continuously output and cut Xuan paper.

[0034] Specifically, the paper feeding and cutting mechanism 2 includes: The main unit is composed of a base plate 21, a protective cover 22 and a side baffle 25. The left side of the protective cover 22 is hinged to the base plate 21, which can open and close at 105°. The Xuan paper branch tube 23 has two ends that can be respectively inserted into the slots 251 of the corresponding side baffles 25 and can be rotatably connected. Preferably, the slots 251 are provided with arc-shaped pads that can reduce wear and noise when the ends of the Xuan paper branch tube 23 rotate. Furthermore, two stops 24 can be sleeved on the Xuan paper branch tube 23. The two stops 24 can be respectively set at both ends of the Xuan paper roll, thereby locking the axial position of the Xuan paper roll on the Xuan paper branch tube 23 and preventing the Xuan paper roll from moving axially along the Xuan paper branch tube 23 and causing paper feeding deviation. Each stop 24 is equipped with a screw-through hand screw, which is convenient for adjusting and locking the position of the stop 24 on the Xuan paper branch tube 23.

[0035] The paper feeding unit includes a drive shaft 27 and a driven shaft 210; Driven shaft 210 is rotatably connected to base plate 21. Specifically, both ends of driven shaft 210 are supported by driven shaft support 29, and driven shaft support 29 is fixed to base plate 21. Multiple driven shaft rubber sleeves 11 are spaced on driven shaft 210. The drive shaft 27 is rotatably mounted directly above the driven shaft 210 with their axes parallel. One end of the drive shaft 27 passes through a side baffle 25 and a handwheel 216 is coaxially fixed to the end. Multiple drive shaft rubber wheels 28 are spaced on the drive shaft 27, and the drive shaft rubber wheels 28 correspond one-to-one with the driven shaft rubber sleeves 211 and abut against each other.

[0036] Preferably, two drive shaft supports 26 are installed on both sides of the base plate 1, and the drive shaft 27 passes through the two drive shaft supports 26. A hand screw 261 is screwed through the drive shaft support 26. A bearing block is rotatably connected to the drive shaft 27. The bearing block is embedded in the drive shaft support 26 and slidably connected to it. The hand screw 261 can push down against the guide block, thereby adjusting the gap between the drive shaft 27 and the driven shaft 210. In essence, it is adjusting the downward pressure and gap between the drive shaft rubber wheel 28 and the driven shaft rubber sleeve 211, thereby adjusting the paper feeding gap and paper clamping force.

[0037] The paper cutting unit includes a guide rod support 212, a blade 213, a blade guide shaft 214, and an anvil 215. The blade 213 is slidably mounted on the blade guide shaft 214. After the guide rod support 212 is installed at both ends of the blade guide shaft 214, the entire assembly is mounted on a base plate 21. The anvil 215 is directly mounted on the base plate 21. The paper cutting blade is fixedly installed on the lower surface of the blade 213, forming a scissor-like structure with the anvil 215. Adjusting the position of the guide rod support 212 allows for adjustment of the relative position of the blade 213 and the anvil 215, ensuring smooth paper cutting.

[0038] The base plate 21 can be fixedly installed on the fixed platform 4 by means of bolts or the like.

[0039] Working principle of paper feeding and cutting mechanism 2: After the Xuan paper roll is inserted into the Xuan paper branch tube 23, the two sides of the Xuan paper roll are lightly fixed by the stop blocks 24; one end of the Xuan paper passes between the drive shaft rubber wheel 28 and the driven shaft rubber sleeve 211, and then passes between the knife bar guide shaft 214 and the anvil 215; the hand-tightening screw of the drive shaft support 26 is adjusted to make the drive shaft caster 28 press the Xuan paper; the output of Xuan paper can be controlled by turning the handwheel 216 counterclockwise; the Xuan paper can be cut by pushing the knife bar 213.

[0040] This utility model adopts a dual-purpose caster wheel, which takes into account both convenient mobility and support stability; four lifting columns work together to ensure overall stability during the lifting of the table; the electric push rod and multi-hinged joint combination realizes the table flipping, which is simple in structure and reliable in operation; the integrated paper feeding and cutting function improves operating efficiency and safety; the magnetic paperweight design is ingenious to ensure that the paper can be firmly fixed at various angles.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
