[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention proposes an HDMI switch supporting 8K signal eARC audio transmission. When the operator needs to pick up the switch body, he can press the pressing block inward, and the pressing block will drive the push rod to move forward together. At this time, the inclined rail block will move upward under the drive of the push rod, so that the inclined rail block and the embedded block lose the card connection. At this time, under the rebound effect of the spring sheet, The elastic roller body can be rotated counterclockwise to recycle the connecting rope. Under the joint restricting action of the Z-shaped slide, the upper linear slide, the corner slide and the lower linear slide, the cleaning plate can first move from the installation long groove to the top surface of the switcher body, and then move forward along the top surface of the switcher body. The top surface of the switcher body can be cleaned by the setting of the brush plate. When the cleaning plate moves to the end of the long rectangular slide, it can stop. This setting is not only convenient and quick to operate, but also realizes automatic cleaning of the shell surface of the switcher body, which is convenient for the operator to directly take the operation. At the same time, the side setting of the pressing block also ensures that the operator's fingers will not be contaminated by dust when pressing the pressing block.

[0023] 2. The HDMI switcher supporting 8K signal eARC audio transmission proposed by the present invention has a clamping component, so that when the triangular card block and the trapezoidal card block lose the clamping effect, the upper slide column can be pushed forward under the elastic force of the extrusion spring, and the concave frame can drive the clamping plate to clamp the plug plugged in the wiring under the support of the lower slide column, so as to realize the clamping and fixing of the plug. When the cleaning plate slides along the rectangular long slideway, the protruding push block can push the protruding push plate to move, and the embedded card block and the square front block lose the clamping effect. To squeeze the L-shaped push rod, under the elastic force of the tension spring, the trapezoidal card block protrudes into the inner groove. When the triangular card block follows the upper sliding column to move to the position of the trapezoidal card block, it can be clamped, and the protruding push block and the protruding push plate are separated. At this time, under the support of the lower sliding column, the concave frame drives the clamping plate to separate from the plug. This setting not only realizes the clamping of the plug, but also can perform automatic fixed separation when the operator cleans the surface of the switch body. It is cleverly used, can achieve multiple effects at the same time, and is convenient to use.

[0024] 3. The HDMI switcher supporting 8K signal eARC audio transmission proposed by the present invention, when the processing of the switcher body is completed, the finger can be placed on the concave-convex layer and the cleaning plate can be pushed forward with force. At this time, the spring sheet is compressed and the connecting rope is extended. When the cleaning plate is pushed into the installation long groove, the protruding push block passes over the protruding push plate. At this time, the embedded card block and the square front abutment block are respectively embedded in the upper end opening of the U-shaped through hole, and the L-shaped push rod is squeezed. Under the transmission action of the square ramp block, the trapezoidal card block can be driven to move downward through the U-shaped rod, so that the triangular card block and the trapezoidal card block lose the card connection, so that the plug can be pressed again, and the next cleaning operation is convenient.
