New description: [New technical field] This creation is an electronic device and a rotating device, in particular an electronic device with a gear device and a rotating device. [Prior Art] • With the advancement of technology, there are more and more electronic devices with touch functions. However, when using the touch function, the touch screen needs to form a comfortable operating angle with the user, so that the user can Use it comfortably for a long time. If a tablet computer is taken as an example, there is already a model that uses a hinge to connect the tablet computer to an external keyboard for the user to select. This type of tablet power month b uses a hub to drive the tablet computer to rotate relative to the external keyboard. The electric moon pack forms an appropriate use angle with the user, and then the external keyboard is used to allow the user to operate for a long time. However, the function of such a fixed screen of the hub is not good. When the user presses the touch screen, the screen will still shake, so that the user usually needs to hold the tablet with one hand to stabilize the screen, and the other hand presses the screen, in operation. Not very convenient. Therefore, in order to meet the needs of users, it is necessary to provide a new type of rotating device to solve the problems of the prior art. [New content] 3 M427477 The main purpose of this creation is to provide a rotating device with a gear device. Another main object of the present invention is to provide an electronic device having the above-described rotating device. To achieve the above objects, the present invention discloses an electronic device and a rotating device thereof, wherein the electronic device includes a screen and a base, and the electronic device includes a hinge, a gear device, and a button. The hub is respectively connected to the screen and the base, wherein the hub includes a gear and a rotating shaft, and the gear is connected to one end of the rotating shaft. The gear unit is detachably coupled to the gear and the button is pressurably contacted with the gear unit. With the above structure, when the gear device is pressed by the button, the gear wheel is disengaged from the gear device, so that the hub can drive the screen to rotate relative to the base; when the gear device is not pressed by the button, the gear meshes with the gear device, so that the screen cannot be rotated. When the gear is meshed with the gear unit, the rotating device of the present invention has the function of fixing the screen of the electronic device. When the gear is disengaged from the gear unit, the rotating device of the present invention can drive the screen to rotate relative to the base. Due to the novel construction of this creation, it can provide industrial use, and it has improved efficiency. Therefore, it applies for a new type of patent according to law. [Embodiment] The above and other objects, features and advantages of the present invention will become more apparent. The specific embodiments of the present invention are described below, and the detailed description thereof will be described below with reference to the accompanying drawings. Please refer to FIG. 1 and FIG. 1a for an embodiment of the electronic device and the rotating device thereof. FIG. 1 is a schematic diagram of an embodiment of the electronic device and the rotating device of the present invention. A schematic view of a prior art embodiment of a rotating device prior to compression. As shown in FIG. 1 , the electronic device 1 of the present invention comprises: a screen 10, a bottom base 20 and a rotating device 30. According to an example of the present creation, the electronic device 1 of the present invention is a tablet computer, and the screen 10 is a touch screen. The screen 20 is connected to the screen 10 through the rotating device 30. As shown in FIG. 1, the base 20 is provided with a set of keyboards. The rotating device 30 is designed to rotate the screen 10 relative to the base 20. It should be noted that the rotating device 30 of the present invention only needs to be installed on one side of the electronic device 1, but the present invention is not limited thereto. As shown in Figs. 1 and 1a, the present rotating device 30 includes a hinge φ 31, a gear unit 32, a button 33, and an elastic member 34. As shown in FIG. 1, the hinges 31 are respectively connected to the screen 10 and the base 20. The gear unit 32 is located on the base 20. The button 33 is pressed into contact with the gear unit 32. The two ends of the elastic member 34 are respectively coupled to the gear unit. 32 and the base 20 are connected. It should be noted that in order to allow the gear unit 32 to be firmly coupled with the base 20, a pair of hooks (not shown) can be inserted into the base 20 to engage with the gear unit 32 to increase the gear unit 32. The elastic member 34 of the present embodiment is a spring, but the present invention is not limited to 5 M427477, and any elastic member is applicable. As shown in FIG. 1a, the hub 31 further includes a gear 311 and a rotating shaft 312. The gear 311 is located at one end of the rotating shaft 312 adjacent to the gear unit 32, and the gear 311 is detachably coupled to the gear unit 32. The gear unit 32 further includes a platform 321 and a retaining wall 322, wherein the retaining wall 322 is coupled to the platform 321 and the button 33 is in contact with the gear unit 32 through the retaining wall 322. It should be noted here that, as shown in FIG. 1a, when the gear unit 32 is not pressed by the button 33, the gear 311 will mesh with the gear unit 32, and the elastic member 34 will be in a natural relaxed state, and the button 33 will be in contact with the retaining wall 322. One side contact, at this time, as shown in Fig. 1, since the gear 311 is engaged with the gear unit 32, the screen 10 is fixed to the base 20 and cannot be rotated. Referring to FIG. 2 and FIG. 2a together, FIG. 2 is a schematic diagram of an embodiment of the electronic device and the rotating device of the present invention, and FIG. 2a is a schematic view of the embodiment of the rotating device according to the present invention. As shown in FIG. 2 and FIG. 2a, when the button 33 is pressed in the direction indicated by the arrow in FIG. 2a, the gear device 32 is moved laterally, so that the gear 311 is disengaged from the gear device 32, and the elastic member 34 is also subjected to the gear device. 32 Compression and compression. At the same time, since the gear unit 32 of the present embodiment is laterally shifted to the right, the gear 311 is moved to the platform 321 by the homeopath and is in contact with the other side of the retaining wall 322. After the gear 311 is disengaged from the gear unit 32, as shown in Fig. 2, the screen 10 can be rotated relative to the base 20 by the pivoting of the hinge 31. In addition, when the button 33. is no longer forced to the gear unit 32, the gear unit 32 is subjected to the restoring force of the elastic member 34, and is laterally pushed to the position where the gear M427477 311 is sprinkled, so that the screen 1() is fixed again. The base 2 is in the state shown in Figs. 1 and 1a. With the above structure, using the electronic device 1 of the present invention, the button 311 and the gear device & the user can rotate the screen 1G' and the screen 1G can be rotated after the button 1 is pressed. Release the button 33, and use the elastic member 34 to return the angle device 32 to the gear 311 to thereby fix the screen 1G, so that when the user uses the function of the touch writing, the screen illuminates the booth 20 I: I don’t need to hold the camp with my hands.
