Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates in particular to a sliding structure and an electronic device therefor. [Prior Art] In the electronic device, in addition to the commonly used buttons that are pressed by the push mode, as the functions of the electronic device are gradually increased, the slide button operated by the sliding push mode becomes one of the necessary components of the electronic device. For example, referring to FIG. 1A and FIG. 1B, the housing 12 of the electronic device is coupled to a sliding structure 14, wherein the housing 12 has a groove 121, and the sliding structure 14 has a sliding portion 141 and two. The extending portion 142 has one end connected to the sliding portion 141 and the other end having a hook portion 143. Therefore, in the process of assembling the housing 12 and the sliding structure 14, the extending portion 142 of the sliding structure 14 is first inserted into the groove 121 of the housing 12, and the housing 12 and the sliding structure 14 are coupled to each other, and The sliding portion 141 is exposed on the outer surface of the housing 12, and has a design of the hook portion 143 at one end of the extending portion 142 for fixing the sliding structure 14 to the housing 12. Although the assembly process of the sliding structure 14 and the housing 12 is relatively simple, the conventional sliding structure 14 is designed to be used for fastening only through the hook portion 143 at the end of the extending portion 142, and is not provided. Good structural stability, and therefore often the problem of the sliding structure 14 falling off the housing 12 during the drop test, reduces the reliability of the product. In order to improve the problem that the sliding structure is easy to fall off, another conventional electronic device and a sliding structure thereof are disclosed in FIG. 2A and FIG. 2B. In the known electronic device, the housing 22 is coupled to a sliding structure 24, and The sliding structure 24 is further coupled to a fixed structure 26. Similar to the above, the housing 22 also has a groove 221. The sliding structure 24 has a sliding portion 241 and an extending portion 242. One end of the extending portion 242 is coupled to the sliding portion 241. The other end is connected to the fixed structure 26. Therefore, in the process of assembling the housing 22, the sliding structure 24 and the fixing structure 26, the extending portion 242 of the sliding structure 24 is first inserted into the groove 221 of the housing 22, so that the housing 22 and the sliding structure 24 are mutually The sliding portion 241 is exposed and exposed to the outer surface of the casing 22, and finally, the fixing structure 26 is coupled to the extending portion 242 of the sliding structure 24 by means of heat fusion, welding, etc., so that the sliding portion can be slid The structure 24 is fixed to the housing 22. Since the structural reliability of the sliding structure 24 and the housing 22 can be improved by adhering to the fixing structure 26 of the sliding structure 24, it is necessary to additionally apply a hot-melt (or welding) process in the assembly process. Therefore, the process yield is lowered, and once the processing fails, the hot melt (or soldering) process is an irreversible method, which is likely to cause waste of the process cost. In view of this, factors such as structural reliability, process simplicity, and product cost have become important technical issues in designing electronic devices. SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a sliding structure and an electronic device thereof, which can firmly connect a sliding structure to an electronic device by using a structural fixing method without increasing the complexity of the process. The increase in the reliability of the structure and the increase in the cost of the product is not increased by 6 1355673. In order to achieve the above object, the present invention provides a sliding structure, which is used in combination with a casing. The sliding structure includes a plate body, a column body and a limiting member, wherein the plate system is at least partially exposed to the casing; The sleeve is connected to the plate body and has a recess; the limiting member has a plug and at least one buckle, the plug is inserted into the recess, and the buckle is fixed on the outer circumference of the cylinder. At the same time, the present invention also provides an electronic device comprising a casing, a plate body, a cylinder and a limiting member, wherein the casing has a groove; the plate body is at least partially exposed to the casing; The system is connected to the plate body and penetrates the groove of the casing, and the column body has a concave portion; the limiting member has a plug and at least one buckle, the insertion pin is inserted in the concave portion, and the buckle is fixed on the column The outer circumference of the body. According to the above description, according to the sliding structure of the present invention and the electronic device for the same, the insertion end of the limiting member is inserted into the concave portion of the cylinder, and the buckle of the limiting member is fixed to the cylinder by the buckle of the limiting member. The outer circumference of the cylinder can be connected to each other by mechanical force between the cylinder and the limiting member, and the plate body, the cylinder body and the limiting Φ piece can be firmly connected to the casing. Compared with the prior art, the sliding structure and the electronic device thereof disclosed by the present invention have high structural reliability, and at the same time, since no irreversible process (for example, hot melting, welding, etc.) is applied, Therefore, the defective products can be reworked, thereby improving the yield of the process and reducing the cost of the product.
