[0041] As shown in the embodiment of the utility model, the connecting assembly 12 includes the first connecting sheet 121 and the second connecting sheet 122 which are arranged in parallel, the first connecting sheet 121 and the second connecting sheet 122 are perpendicular to the table top connecting plate 11 and are arranged on the two sides of the stand column respectively; it is pointed out here that the fixing mode of the first connecting sheet 121 and the second connecting sheet 122 and the table top connecting plate 11 can adopt welding, screwing or the structure of one-piece forming. Figure 3 As shown in the embodiment of the utility model, the connecting assembly 12 includes the first connecting sheet 121 and the second connecting sheet 122 which are arranged in parallel, the first connecting sheet 121 and the second connecting sheet 122 are perpendicular to the table top connecting plate 11 and are arranged on the two sides of the stand column respectively; it is pointed out here that the fixing mode of the first connecting sheet 121 and the second connecting sheet 122 and the table top connecting plate 11 can adopt welding, screwing or the structure of one-piece forming.

[0042] In the embodiment of the utility model, the first connecting sheet 121 stand column can be connected relatively rotatably, one side of the adjuster 131 is connected with the other side of the stand column, and the other side of the adjuster 131 is connected with the second connecting sheet 122; when the adjusting hand wheel 132 is rotated by a set angle, the adjuster 131 is relatively rotated to adjust the angle of the table plate.

[0043] In the above embodiment, the table top connecting plate 11 is connected with the table plate, the connecting assembly 12 fixed on the table top connecting plate 11 is rotatably connected with the stand column, and the adjusting assembly 13 arranged between the connecting assembly 12 and the stand column, so that the rotating hand wheel 132 can realize the angle adjustment of the table plate and the stand column; compared with the prior art, only the rotating adjusting hand wheel 132 can realize the angle adjustment of the table plate, thereby improving the convenience of the angle adjustment of the table plate, and the internal clamping structure 131c of the adjuster 131 is arranged to clamp after being adjusted to the set angle, thereby improving the reliability of the angle adjustment.

[0044] On the basis of the above embodiment, in some embodiments of the utility model, some embodiments of the adjuster 131 are as follows: Figure 4 and Figure 5As shown in the middle, the adjuster 131 includes a fixed disc 131a fixedly connected with the column, a movable disc 131b fixedly connected with the second connecting sheet 122, and a locking structure 131c arranged between the fixed disc 131a and the movable disc 131b, the adjusting hand wheel 132 is connected with the locking structure 131c, the fixed disc 131a is arranged opposite to the movable disc 131b, and the fixed disc 131a and the movable disc 131b are relatively static when the locking structure 131c is locked, and the fixed disc 131a and the movable disc 131b can relatively rotate when the locking structure 131c is unlocked. By rotating the adjusting hand wheel 132, the locking and unlocking of the fixed disc 131a and the movable disc 131b can be realized, when locked, the movable disc 131b cannot rotate relative to the fixed disc 131a, and when unlocked, the movable disc 131b can rotate relative to the fixed disc 131a, by arranging the structure in this form, the rotation of the connecting assembly 12 relative to the column when unlocked can be realized; of course, it should be pointed out here that the locking and fixing of the movable disc 131b and the fixed disc 131a have various structure forms in the prior art, for example, the fixing can be realized by extrusion, or the fixing can also be realized by buckling and the like.

[0045] In some embodiments of the present application, please continue to refer to Figure 4 and Figure 5 , the locking structure 131c includes a gear ring 131c1 arranged on the inner circumferential side wall of the fixed disc 131a, a clamping block 131c2 which can be close to or away from the gear ring 131c1, a sliding channel 131c3 arranged on the fixed disc 131a for sliding of the clamping block 131c2, and a driving shaft 131c4 for driving the clamping block 131c2 to move radially, the driving shaft 131c4 is coaxially connected with the adjusting hand wheel 132. In this way, since the clamping block 131c2 can slide in the sliding channel 131c3, when the clamping block 131c2 engages with the gear ring 131c1, the movable disc 131b cannot continue to rotate due to the limitation of the sliding channel 131c3, and when the clamping block 131c2 is separated from the gear ring 131c1, the movable disc 131b can relatively rotate relative to the fixed disc 131a. Of course, it should be pointed out here that the driving shaft 131c4 has various ways to drive the clamping block 131c2 to move radially, for example, the arc-shaped spiral groove hole can be combined with the limiting column on the clamping block 131c2, so that the arc-shaped spiral groove hole gradually pulls the clamping block 131c2 towards the center when rotating, to realize the radial movement of the clamping block 131c2; or the hook structure in the embodiments of the present application is adopted, in the embodiments of the present application, please continue to refer to Figure 4 and Figure 5 , the driving shaft 131c4 has a hook which pulls the clamping block 131c2 to move radially, and the clamping block 131c2 has teeth which engage with the gear ring 131c1. Specifically as Figure 5As shown in Figs. 13 and 14, the hook is connected with the groove inside the clamping block 131c2, so that the hook drives the clamping block 131c2 to move towards the inside when the driving shaft 131c4 rotates.

[0046] In the embodiment of the present application, please continue to refer to Figure 4 and Figure 5 The clamping structure 131c further has a coil spring 131c5, one end of which is fixedly connected with the fixed disc 131a, and the other end is connected with the clamping block 131c2, for driving the clamping block 131c2 to abut against the gear ring 131c1. Through the arrangement of the coil spring 131c5, the abutment of the clamping block 131c2 and the gear ring 131c1 can be maintained, and only when the driving shaft 131c4 rotates, the clamping block 131c2 is pulled to move towards the inside, and the driving shaft 131c4 is restored to the original position under the action of the force of the coil spring 131c5 when there is no external force, so that the adjusted angle can be automatically maintained after the angle is adjusted.

[0047] Optionally, in order to further improve the convenience of operation, the connecting assembly 12 further comprises a damping adjusting assembly 13123 arranged between the first connecting piece 121 and the stand; as shown in Figs. Figure 3 and Figure 6 The damping adjusting assembly 13123 comprises a friction plate 123a arranged between the first connecting piece 121 and the stand, and a fastener 123b for adjusting the pressing force between the first connecting piece 121 and the stand. The fastener 123b herein comprises a nut as shown in Fig. Figure 6 One side of the nut abuts against the friction plate 123a, and the other side extends into the inside of the stand. The bolt is screwed through the first connecting piece 121, the friction plate 123a and the nut, and the friction force can be adjusted by adjusting the tightness of the screwing of the bolt and the nut, so that the force required for rotating the table board can be controlled. In addition, in the embodiment of the present application, the side of the friction plate 123a towards the stand has a protruding reinforcing rib 123a1. The arrangement of the protruding reinforcing rib 123a1 can improve the friction force, and the structure of the reinforcing rib 123a1 can also be arranged as spaced strips, or as a closed ring structure as shown in Fig. Figure 6 to improve the uniformity of contact.

[0048] In the embodiment of the present application, in order to improve the convenience of operation, as shown in Fig. Figure 7 The hand wheel 132 comprises a rotating disc 132a and a handle 132b connected with the rotating disc 132a, and the handle 132b extends radially to the outside of the rotating disc 132a. Through the arrangement of the handle 132b, the rotating disc 132a can be rotated by only pulling the handle 132b during specific operation, and the force required for operation is reduced by using the principle of lever.
