Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, fig. 2 and fig. 3, the utility model relates to a keyboard scissors structure suitable for narrow type key cap, including 1

outer scissors

1 and 2

interior scissors

2, 2 interior scissors 2 intervals certain distance set up with outer scissors inside to be connected with outer scissors 1 rotation, outer scissors 1 and interior scissors 2 normal running fit each other press the keyboard button, outer scissors 1 and interior scissors 2 push down thereupon, the rotatory transmission of cooperation.

As shown in fig. 4 and 5, the outer scissors 1 comprise an outer scissors base arm 101, a pair of outer scissors side arms 102, an outer scissors inner frame 103 and a pair of outer scissors arms 104, wherein an outer scissors arm 104 is connected between the outer scissors inner frame 103 and the adjacent outer scissors side arms 102 and forms a space 105 for accommodating the inner scissors, respectively, and the outer scissors inner frame 103 has a middle hollow 106. As shown in fig. 5 and 6, the inner pair of scissors 2 has a rectangular frame structure, the inner pair of scissors 2 includes a pair of inner pair of scissors bottom arms 201, a pair of inner pair of scissors side arms 202 and an inner pair of scissors crossbar 203, and the inner pair of scissors 2 further has a groove 204 adapted to the outer pair of scissors crossbar 104.

As shown in fig. 6, 7 and 8, a pair of connecting shafts 205 is provided on the outer side surfaces of the inner scissors side arms 202, connecting holes 107 are symmetrically provided on the side surfaces of the outer scissors inner frames 103 opposite to the outer scissors side arms 102, connecting holes 107 are also symmetrically provided on the side surfaces of the outer scissors side arms 102 opposite to the outer scissors inner frames 103, and the connecting holes of the outer scissors inner frames 103 and the connecting holes 107 on the outer scissors side arms 102 adjacent thereto constitute a pair of connecting holes adapted to the connecting shafts 205 for connecting the outer scissors and 2 inner scissors.

Or the utility model discloses a be provided with a pair of connecting hole on the lateral surface of interior scissors side arm 202, the symmetry is provided with the connecting axle on the side relative with outer scissors side arm 102 of outer scissors inside casing 103, and the symmetry is provided with the connecting axle on the side relative with outer scissors inside casing 103 of outer scissors side arm 102, and a pair of connecting axle with connecting hole looks adaptation is constituteed to the connecting axle of outer scissors inside casing 103 and the connecting axle on the outer scissors side arm 102 adjacent with it for connect outer scissors and 2 interior scissors.
