Specifically, the clamping module includes a clamping base having a first plate, a column, a second plate, and a clamping fastener. The first plate is disposed on the upper surface of the tabletop. The column is fixed to the edge of the first plate and adjacent to the side of the tabletop. The second plate is fixed to the column and spaced apart from the first plate, and located below the lower surface of the tabletop. The clamping fastener is screwed onto and passes through the second plate. By rotating the clamping fastener, the distance between the clamping fastener and the second plate can be adjusted to bring the clamping fastener abutting against the lower surface of the tabletop, thereby securing the clamping base firmly to the tabletop.

[0003] However, the above-mentioned clamp designs all require users to go around to the back of the table and reach under the table to operate the clamping components, and it is not possible to operate the clamping components directly above the table. Utility Model Content

The locking fastener 25 passes through the upper clamping body 21 and is partially located in the through groove 241.

[0058] Please see Figure 4The rotating adjusting cylinder 3 includes a hollow solenoid 31, an outer shell 32, and a receiving space 33. The hollow solenoid 31 has an external threaded portion 311, a head 312, and a through hole 313. The external threaded portion 311 extends outward from the head 312 and is screwed into the threaded hole 14. The cross-sectional area of ​​the head 312 is larger than that of the external threaded portion 311. The through hole 313 is formed through the head 312 and the external threaded portion 311. The outer shell 32 has a shell 321 and a cover 322. The shell 321 is generally a hollow cylinder. The cover 322 is located at one end of the shell 321 and has a recess 3221 and an opening 3222 located at the center of the recess 3221.

The housing 41 is generally circular and bowl-shaped, and has a protruding ring portion 411. The through hole 42 is formed through the housing 41 and has a non-circular cross-section. The nut 43 is located at the bottom of the housing 41. The friction plates 44 are respectively located on the upper and lower sides of the housing 41. The stop washers 45 are respectively located between the housing 41 and the friction plates 44, and are fixed to the housing 41. The bowl-shaped washer 46 is located between the nut 43 and the friction plates 44.

[0060] Please also refer to Figure 7 The shaft 5 comprises a head section 51, a fixed section 52, an externally threaded section 53, and an extension section 54 connected in sequence. The cross-sectional area of ​​the head section 51 is larger than that of the fixed section 52, the externally threaded section 53, and the extension section 54, and abuts against the upper side of the housing 41. The fixed section 52 is provided with a through hole 42, the friction plate 44, the stop washer 45, and the cup-shaped washer 46. The externally threaded section 53 is located on the lower side of the housing 41, and a nut 43 is screwed onto the externally threaded section 53, and together with the head section 51, it is clamped on the upper and lower sides of the housing 41, so that the head section 51 is fixed to the fixed cylinder 4. The extension section 54 is located in the accommodating space 33 and is provided with a through hole 313 of the hollow spiral tube 31 and a through groove 241 of the hollow seat 24, and is fixed to the upper clamp 21 via a locking fastener 25.

[0061] The first friction element 6 is generally a hollow elongated cylindrical shape, sleeved on the shaft 5 and passing through the through hole 313 of the hollow solenoid 31, thereby positioning the first friction element 6 between the shaft 5 and the hollow solenoid 31. The second friction element 7 is generally annular, fixed to the cover 322 of the outer shell 32, and located between the outer shell 32 and the fixing cylinder 4. In this embodiment, the first friction element 6 and the second friction element 7 are made of polyoxymethylene (POM) material, which can prevent the shaft 5 from directly contacting the hollow solenoid 31 and the outer shell 32 from directly contacting the outer shell 41, thus preventing wear when the outer shell 32 and the hollow solenoid 31 rotate. It can also prevent gaps from forming between the shaft 5 and the hollow solenoid 31, thus preventing back-and-forth and left-and-right swaying.

[0062] Please see Figure 6 The top cylinder 8 is located at the end of the fixed cylinder 4 away from the rotating adjusting cylinder 3, and includes a shell portion 81, a through hole 82, a fixing plate 83, a pivot member 84, two friction plates 85, two stop washers 86, and a bowl-shaped washer 87. The shell portion 81 is generally circular and bowl-shaped. The through hole 82 is formed through the shell portion 81 and has a circular cross-section. The fixing plate 83 is generally circular and is fixed to the protruding ring portion 411 of the outer shell 41, and has a central hole 831. The pivot member 84 has a screw 841 and a nut 842. The screw 841 passes through the through hole 82 and the central hole 831 of the fixing plate 83, and the nut 842 is screwed to the screw 841 and located on the lower side of the fixing plate 83. The friction plates 85 and the stop washers 86 are through which the screw 841 passes and are located on the upper and lower sides of the shell portion 81, respectively. A bowl-shaped washer 87 is used to pass through a screw 841 and is located between a fixing plate 83 and a nut 842. The cross-section of the screw 841 matches the cross-section of the central hole 831 and is a non-circular cross-section. The fixing plate 83 is fixed to the housing 41, so that the pivot member 84 moves with the fixing plate 83. This allows the housing 81 to rotate relative to the housing 41 and the fixing plate 83 about the pivot member 84. The support arm 9 is used to support the display 2000 and is fixed to the upper side of the housing 81 and moves with the housing 81. Therefore, the support arm 9 can also rotate relative to the housing 41 and the fixing plate 83 about the pivot member 84. The part of the support arm 9 fixed to the housing 81 may be provided with a tilting structure (not shown), so that the support arm 9 can tilt relative to the top cylinder 8.

[0063] The following describes the operation of the table-clamping support device 1000 of this application. Please refer to [link / reference]. Figure 7The upper clamping body 21 of the upper clamping member 2 is placed against the upper surface 3001 of the table 3000. At this time, the rotating adjusting cylinder 3 is located above the table 3000, the top plate 13 is accommodated in the accommodating space 33, and the upper clamping body 21 and the sliding groove 15 are located outside the accommodating space 33 and adjacent to the outer cylinder shell 32 (the distance between the upper clamping body 21 and the lower clamping body 16 is pre-adjusted to be greater than the thickness of the table 3000). An external force is applied to make the outer cylinder shell 32 of the rotating adjusting cylinder 3 rotate on its own. The hollow solenoid 31 is fixed to the outer cylinder shell 32 and can rotate synchronously with the outer cylinder shell 32, so that the hollow solenoid 31 can rotate relative to the screw hole 14, thereby linking the lower clamping member 1. Because the protrusion 23 of the upper clamp 2 slides in the groove 15, the lower clamp 1 is limited by the protrusion 23 of the upper clamp 2 in the groove 15 and cannot rotate relative to the hollow solenoid 31. Instead, it moves linearly along the direction of gravity G (along the groove 15) (that is, the rotational motion is converted into linear motion). In this way, the lower clamp 16 can move closer to the lower surface 3002 of the tabletop 3000 until it abuts against the lower surface 3002 of the tabletop 3000. Figure 8 As shown, the lower clamp 16 and the upper clamp 21 can jointly clamp the tabletop 3000. To detach the tabletop support device 1000 from the tabletop 3000, simply apply another external force to cause the rotating adjusting cylinder 3 to rotate in the opposite direction, moving the lower clamp 16 away from the lower surface 3002 of the tabletop 3000. The distance between the upper clamp 21 and the lower clamp 16 can be adjusted by causing the rotating adjusting cylinder 3 to rotate.

[0064] In summary, the table clamping support device of this application can be operated to clamp onto the table by rotating the rotating adjustment cylinder located above the table, which is very convenient to use.
