The limiting rod 170 is provided with a limiting hole 172. One end of the connecting rod 160 penetrates through the limiting hole 172 to be connected with the clamping member 152, and the other end is connected with the supporting member 180. The elastic member 156 is located at one side of the limiting rod 170, and the diameter of the limiting hole 172 is smaller than that of the elastic member 156, so that the opening of the limiting hole 172 limits the moving range of the elastic member 156. When the user compresses the elastic member 156 to separate the gear 132 and the fastening member 152, the elastic member 156 cannot pass through the limiting hole 172, so that the elastic member 156 can store enough elastic potential energy to facilitate the elastic member 156 to restore to the original position at a later stage to connect the gear 132 and the fastening member 152. The shape of the limiting rod 170 is not limited, and may be a cylinder or a rectangular parallelepiped.

Further, in other embodiments, the limiting rod 170 may further be provided with a hanging buckle (not shown), and the fastening member 152 is provided with a hanging buckle hole matched with the hanging buckle. When the user compresses the elastic member 156, the latch can be engaged with the latch hole to lock the latch member 152 at the current compressed position, so as to reduce the labor intensity of the user. After the plate body 112 is adjusted to the position required by the user, the hanging buckle is taken down from the hanging buckle hole, and the spring is restored to the natural state. This arrangement provides more convenience to the user in adjusting the position of the plate body 112, avoiding the need for the user to continue to compress the resilient member 156 at all times during the adjustment process.

When a user needs to adjust the angular position of the plate 112, the elastic member 156 is compressed, so that the rack and the gear 132 are separated, and the position of the plate 112 can be adjusted by rotating the gear 132. When the plate 112 is rotated to the desired position by the user, the contact compresses the resilient member 156, causing the rack and pinion 132 to re-engage with each other, and the plate 112 is secured in the current position. In this embodiment, the elastic member 156 is a spring. When the spring is in a natural state, the gear 132 is meshed with the rack, and the plate body 112 is fixed; when the spring is compressed to a certain position, the gear 132 and the rack are separated from each other, and the position of the plate body 112 can be freely adjusted by the rotation of the gear 132. Of course, in other embodiments, other materials may be used for the resilient member 156, such as rubber, foam, sponge, etc.

Referring to fig. 7, fig. 7 is a schematic structural diagram of the drawing board body 110 when rotated to be parallel to the ground. The connecting rod 160 may be a first segment 161 and a second segment 163 connected to each other. The second segment 163 is connected to the support member 180 at one end and to the gear 132 at the other end. One end of the first segment 161 near the rack penetrates through the limiting hole 172 to connect with the fastening member 152, and the other end is connected with the second segment 163 in a sliding manner, so that the first segment 161 can slide along the length direction of the spring. The first segment 161 is provided with a groove (not shown) along the length direction, and the second segment 163 is provided with a protrusion (not shown) matching with the groove. When the user needs to adjust the position of the plate 112, a certain force may be applied to the rack to compress the spring, and the first section 161 slides along the opening direction of the strip-shaped groove while compressing the spring until the gear 132 is separated from the rack, and the user can rotate to adjust the angular position of the plate 112. When the plate 112 is adjusted to a desired position, the user can cancel the force applied to the rack, and the spring will return to the natural state under the elastic action, so that the gear 132 and the rack are engaged with each other, and the plate 112 is fixed in the current state.

Referring to fig. 2, in another embodiment, the connecting rod 160 may also be a third segment 165, a fourth segment 167 and a fifth segment 169 which are connected in turn. The end of the third segment 165 remote from the fourth segment 167 is connected to the gear 132, the end of the fifth segment 169 remote from the fourth segment 167 is rotatably connected to the support member 180, and the spring is sleeved on the third segment 165. The rotational connections between the third 165, fourth 167 and fifth 169 segments may be hinged. The pivotal connection between the third section 165, the fourth section 167 and the fifth section 169 ensures that the third section 165, the fourth section 167 and the fifth section 169 are flexible when a user compresses or releases the spring, thereby increasing the flexibility of the telescoping member 154. The third section 165 is capable of reciprocating within the limit hole 172, and the gear 132 is connected to the third section 165, so that the rack is also capable of reciprocating linearly along the length of the third section 165. In this embodiment, the third section 165 and the rack may be detachably connected by a screw, a bolt, or other connecting members, so that a user can replace a new spring in time when the spring is elastically disabled.

When the board body 112 is used, the user can adjust the position of the board body 112 according to personal habits. When the user needs to adjust the position of the plate body 112, the arc-shaped rack is pressed downwards, the spring is in a compressed state, the hanging buckle hole in the arc-shaped rack is locked with the hanging buckle, the gear 132 is separated from the arc-shaped rack at the moment, and the plate body 112 can rotate at will. When the plate body 112 is adjusted to the position that the user is accustomed to, the hanging buckle is taken down from the hanging buckle hole, the spring is restored to the natural state, at the moment, the gear 132 is meshed with the arc-shaped rack, and the plate body 112 is fixed at the position that the user has adjusted.

The support member 180 serves to support the plate body 112. The structure of the support member 180 is not limited as long as it does not hinder the rotation of the plate body 112. In this embodiment, the supporting member 180 includes a first supporting member 181 and a second supporting member (not shown), which are spaced apart from each other, as shown in fig. 2. In order to facilitate the user to adjust the height of the drawing board 100 at will, the first support 181 and the second support may be arranged in a liftable manner.
