Specifically, the upper part of the swing angle linkage plate 271 is rotatably disposed on the display screen lifting bracket 23, a sliding hole 2711 is formed at the lower part of the swing angle linkage plate 271, and a sliding shaft 231 inserted into the sliding hole 2711 is disposed on the side edge of the display screen lifting bracket 23; meanwhile, a protrusion 2712 protruding toward the swing ejector 16 is protruded at the lower portion of the swing angle linkage plate 271. Meanwhile, the end of the display screen lifting bracket 23 is upwardly arranged on a connecting block 232, and the upper part of the swing angle linkage plate 271 is rotatably connected with the connecting block 232 through a bolt 273.

When the swing angle linkage plate 271 moves up to the positive side of the swing ejecting member 16, the swing ejecting member 16 contacts with the protrusion 2712 of the swing angle linkage plate 271, and the protrusion 2712 is pushed outward by the swing ejecting member 16, so that the sliding hole 2711 of the swing angle linkage plate 271 slides along the sliding shaft 231 with the bolt 273 at the upper part of the swing angle linkage plate 271 as the center point, thereby swinging for a certain angle. The combination of the sliding hole 2711 and the sliding shaft 231 defines the swing path and angle of the swing angle linkage plate 271, so that the stability and accuracy of the swing angle linkage plate 271 during swinging are improved, and the phenomenon of random swinging is avoided.

Specifically, one end of the first return spring 272 is connected to the upper portion of the swing angle linkage plate 271, and the other end is connected to the lower portion of the side of the display screen lifting bracket 23. In the process that the swing angle linkage plate 271 swings with the bolt 273 at the upper part as the central point, the upper part of the swing angle linkage plate 271 drives the display screen 3 to swing at a corresponding angle, the first return spring 272 is stretched to generate corresponding deformation, and after the acting force generated by the swinging action disappears, the first return spring 272 provides a restoring acting force to reset.

Specifically, the swinging ejector 16 mainly comprises a bearing seat 161 disposed on the inner wall of the chassis 1, and at least one bearing 162 rotatably disposed on the bearing seat 161. When the swing angle linkage plate 271 rises to the lower part of the protrusion 2712 to contact with the lower edge of the bearing 162, the swing angle linkage plate 271 continues to rise, the protrusion 2712 and the bearing 162 generate a relative acting force, the protrusion 2712 drives the bearing 162 to rotate until the swing angle linkage plate 271 rises to the positive side of the protrusion 2712, and in the process, the bearing 162 pushes the protrusion 2712 outwards to rotate the swing angle linkage plate 271. Therefore, the rotation of the rotatable bearing 162 provides an auxiliary function for the swing angle linking plate 271 to ascend, and prevents the influence of excessive resistance on the swing angle linking plate 271 from continuously ascending when the protrusion 2712 is just in contact with the bearing 162.

Example three:

the main difference between this embodiment and the first or second embodiment is: as shown in fig. 6, a microphone lifting and positioning mechanism 56 is disposed in the casing 1, the microphone lifting and positioning mechanism 56 includes a lifting slide plate 561 disposed on the inner wall of the casing 1, a microphone positioning frame 562 disposed on the upper end of the lifting slide plate 561, and a second return spring 563 connected between the lower end of the lifting slide plate 561 and the inner wall of the casing 1, wherein a microphone through hole 5621 for the microphone 6 to pass through is formed on the microphone positioning frame 562, and a pushing connecting block 5611 located right below the microphone lifting support 52 is disposed at the lower end of the lifting slide plate 561.

Meanwhile, a rubber plug 564 matched with the microphone extension opening 12 is arranged on the microphone perforation 5621 of the microphone positioning frame 562. The rubber plug 564 has certain elasticity and flexibility, and plays a certain role in protecting the microphone 6; meanwhile, after the microphone 6 rises to the right position, the rubber plug 564 is matched with the microphone extension port 12 to seal the microphone extension port 12, so that the dust-proof effect in the case 1 is achieved.

In the process that the microphone lifting support 52 drives the microphone 6 to do lifting movement, the microphone 6 is limited in the microphone perforation 5621, so that the phenomenon of random swing cannot occur, and the microphone 6 can stably ascend and descend.

Specifically, in the process that the microphone lifting support 52 drives the microphone 6 to descend, the microphone lifting support 52 synchronously pushes the pushing connecting block 5611 at the lower end of the lifting sliding plate 561 downwards, so that the lifting sliding plate 561 drives the microphone positioning frame 562 to synchronously move downwards, and the second return spring 563 is stretched to deform; when the microphone lifting support 52 drives the microphone 6 to lift, the microphone lifting support 52 releases the acting force on the lifting slide plate 561, and the lifting slide plate 561 drives the microphone positioning frame 562 to reset and move upwards under the action of the elastic restoring force of the second return spring 563, so that the microphone positioning frame has an automatic return function; in the process of the microphone 6 being lifted or lowered by the microphone lifting support 52, the microphone 6 is positioned by the microphone positioning frame 562 of the microphone lifting positioning mechanism 56, so that the microphone 6 is prevented from swinging randomly, and the stability and accuracy of the lifting and lowering of the microphone 6 are improved.
