[0022] The following will further elaborate on the present utility model in conjunction with the accompanying Figures 1-4 drawings.

[0023] Example 1. Referring to Figures 1-4 , in this example, in order to solve the problem that the existing keyboard has three connection modes, namely Bluetooth connection, wired connection, and wireless connection, but when the existing keyboard is connected wirelessly and via Bluetooth, the wired connection interface is exposed, which may be affected by dust and water stains, resulting in damage to the wired interface of the keyboard and affecting the normal use of the keyboard. The present utility model discloses a three-mode Bluetooth keyboard,

[0024] which includes a keyboard body 1. A wired connector slot 2 is opened at the rear side of the keyboard body 1. Slide grooves 3 are opened on both the upper and lower sides of the wired connector slot 2. A protection plate 4 is inserted into the inner cavity of the wired connector slot 2. Sliding plates 5 are fixedly installed on both the upper and lower sides of the protection plate 4. The two sliding plates 5 are embedded in the slide grooves 3, and the two sliding plates 5 are slidably arranged inside the corresponding slide grooves 3. A side baffle 6 is fixedly installed on the side of the protection plate 4 close to the wired connector slot 2.

[0025] Two positioning grooves 7 are opened in the inner cavity of the wired connector slot 2. A housing 8 is fixedly installed on the front side of the protection plate 4. A positioning rod 9 is inserted on the surface of the housing 8. The positioning rod 9 is adapted to the positioning groove 7.

[0026] A limiting plate 10 is fixedly installed on the surface of the positioning rod 9. A telescopic spring 11 is sleeved outside the positioning rod 9. The telescopic spring 11 is located between the limiting plate 10 and the inner wall of the housing 8. The front end of the positioning rod 9 penetrates through the front side of the housing 8, and a handle 12 is fixedly installed at the front end of the positioning rod 9.

[0027] The specific working principle is as follows: By setting the wired connector slot 2, when the user uses the wired connector slot 2, first pull the handle 12 outwards. The movement of the handle 12 drives the positioning rod 9 to move out of the positioning groove 7. Then, the user slides the protection plate 4 inside the wired connector slot 2 by using the sliding plates 5 on both the upper and lower sides. At this time, the plug inside the wired connector slot 2 is exposed, and the user can insert the connector into the keyboard body 1 for use. By setting the protection plate 4, external protection is provided for the connector end inside the wired connector slot 2.

[0028] Example 2. Referring to Figures 1-4 , in this example, in order to solve the problem of soreness in the palm when using the existing keyboard, based on the same concept as in Example 1 above, this three-mode Bluetooth keyboard further includes:

[0029] A knob 13 is movably arranged at the rear side of the keyboard body 1, and a three-mode indicator label 14 is marked on the rear side of the keyboard body 1. The three-mode indicator label 14 is located outside the knob 13.
