[0002] Table cards, also called seat cards, are usually placed on the desks of the corresponding seats to indicate the titles of the attending units or individuals (such as positions or names, etc.). Table cards for traditional meetings are made of paper or copper, and are mostly made temporarily, only used to display names and indicate the identities of participants. Generally, they are printed, printed in color, engraved, etc., and the appearance is relatively rough, which cannot reflect the modern meeting environment. Moreover, they are made temporarily each time and are discarded after use. When there are many participants, it not only wastes a lot of manpower and material resources, but also has low production efficiency, pollutes the environment, is too costly, and is seriously wasteful. For this reason, the industry has developed a variety of electronic table cards to replace traditional table cards and reduce waste. For example, a Chinese utility model patent with authorization announcement number CN213844584U discloses a stably placed wireless electronic table sign, including an electronic table sign bottom plate, a first fixing plate is arranged in the middle of the left side of the electronic table sign bottom plate, a second fixing plate is arranged in the middle of the right side of the electronic table sign bottom plate, an electronic table sign is arranged in the middle of the base surface of the electronic table sign bottom plate, a first pressing rod is arranged in the middle of the left side of the electronic table sign, a first limiting plate is arranged at the left end of the first pressing rod, the right end of the first pressing rod is embedded in the interior of the electronic table sign and is connected with a first connecting plate, a first limiting spring is arranged on the right side of the first connecting plate, a baffle is arranged at the right end of the first limiting spring, a second pressing rod is arranged in the middle of the right side of the electronic table sign, and a second limiting plate is arranged at the right end of the second pressing rod. Although the device has high stability, it has the problem of being unable to adjust the height, and it is difficult to meet the requirements of different meeting people for table signs.

[0015] 3. The anti-drop mechanism of the utility model is used to prevent the table card body from dropping after being raised. When the table card body needs to be raised or lowered, the adjustment knob needs to be pulled outward first. At this time, the spring is stretched, and the slider moves along the slide slot so that the adjustment knob can move along the rotating rod but does not rotate. Then the adjustment knob is turned, and the adjustment knob drives the rotating rod to rotate. After the table card body is adjusted to a suitable height, the adjustment knob is released. Due to the rebound of the spring, the adjustment knob is pulled inward, so that the adjustment knobs at both ends clamp the table card body, thereby preventing the table card body from dropping.
