Description of the invention: v [Technical field to which the invention pertains] The present invention relates to an input device, and more particularly to a computer keyboard. [Prior Art] With the increasing popularity of computers, the frequency of people using computers is getting higher and higher. Many workers report that they stay in front of computers for a long time. It is seen that the thin input is mainly realized by the keyboard, so that the front half of the user's palm needs to fall on the keyboard. Because the keyboard has - 疋 question degree 'the user's wrist is always kept bent, and the desktop is usually hard to place the key. So, long-term operation of the keyboard will make the user feel tired, not only work inefficient And it also affects the health of the wrist, causing a lot of trouble for the keyboard users. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a keyboard that can alleviate user fatigue. A keyboard includes a body, a plurality of buttons on the front side of the body, a cushion, a connecting line, and a fixed terminal. The fixed terminal is disposed on the back of the body, the connecting wire end is connected to the fixed terminal (4), and the other end is connected to the inflatable raft. The above keyboard is connected with an inflatable cushion by a connecting wire, and the user can position the inflatable cushion according to his own requirements, and rest the wrist on the inflatable cushion when operating the keyboard to relieve fatigue and protect the wrist. The cable also ensures that the inflatable cushion is not lost. [Embodiment] Please refer to FIG. 1 and FIG. 2, which are a perspective view and a rear view of a keyboard 1 of a preferred embodiment. The keyboard 10 includes a body 1 〇〇, a plurality of buttons 1 〇 2, 6 1354219, two air cushions 104, two connecting wires 1 〇 6, two fixed terminals n 〇 and two blocking portions 114. The body 100 is in the shape of a flat cuboid, and the plurality of buttons 102 are located on the front side of the body 100 for generating corresponding input commands in response to user button actions. Two embedding grooves 108 and two receiving portions 112 are disposed on the back surface of the main body 1 . Both of the buried slots 108 extend into one side of the body 1 , which is the side facing the user. Two fixed terminals 11A are respectively disposed in the two embedding slots 108. One end of the connecting wire 106 is connected to the fixed terminal 11A, and the other end is connected to the air filling pad 104. The inflatable cushion 104 is elliptical, hollow and made of an elastic material such as a rubber material. The inflatable cushion 104 is provided with a gas nozzle 142 for inflation and deflation, by which the user can inflate and deflate the inflatable cushion 1〇4. The two accommodating portions 112 are two rectangular recesses formed on the back surface of the main body 100, and respectively penetrate the two embedding grooves 1 〇 8 , and the volume of the accommodating portion 丨 12 is larger than the volume of the inflatable cushion 104. The two inflatable cushions 104 are respectively accommodated. The two shielding portions 114 respectively cover a part of the opening of the two receiving portions 112 to prevent the inflatable cushion 104 from accidentally falling out from the receiving portion 112. The shielding portion 114 is an elastic mesh structure to facilitate the insertion and removal of the inflatable cushion 1〇4. When the keyboard 10 is in use, the inflatable cushion 1〇4 is placed on the side of the body 1 facing the user, and the connecting line 106 is located in the embedding slot 1〇8 to ensure the smooth placement of the keyboard 10. . The user's hands and wrists can be placed on the two inflatable cushions 104 to provide comfort to the user's keyboard operation, reduce fatigue, improve work efficiency, and protect the wrist. Since the inflatable cushion 1〇4 7 1354219 is fixed on the body 10 by the connecting line 106, the user can adjust the position of the inflatable cushion 104 according to his own requirements, while ensuring that the inflatable cushion 104 does not move too much, and avoids falling to the ground. Possible. When the keyboard 10 is not used for a long time, the inflatable cushion 104 can be put away, and the state is as shown in FIG. The user can release the gas in the inflatable cushion 104, reduce the volume of the inflatable cushion 104, and place the inflatable cushion 1〇4 and the connecting wire 1〇6 into the accommodating portion 112 of the body 100. In this way, the keyboard 1 can be placed smoothly as usual. In other embodiments, if the fixed terminal no is located at the edge position, the partial connection line 106 may be placed in the embedding slot 1〇8. It is to be understood by those skilled in the art that the above embodiments are only intended to illustrate the invention, and are not intended to limit the invention, as long as it is within the spirit of the invention Changes and modifications are intended to fall within the scope of the invention.
