[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention sets a detection mechanism. By holding the detection machine body and moving it downward, the detection machine body is placed inside the support seat. The image data of the VGA device can be received and transmitted through the video capture card, and the signals of 16 VGA devices can be detected simultaneously through the signal detection port.

[0020] 3. The present invention provides a buffer mechanism. After the detection machine body is placed into the interior of the support seat, the buffer plate contacts the bottom of the detection machine body, and the movement of the buffer plate drives the connecting plate to move. The movement of the connecting plate pushes the second spring to be squeezed and deformed, thereby supporting the detection machine body. In the process of the buffer plate moving downward, it contacts the top of the buffer pad, which can further reduce the collision of the detection machine body and prevent the parts inside the detection machine body from being damaged and unable to be used normally due to vibration.

[0021] 4. The present invention sets a positioning mechanism. After the transmission cable is plugged into the signal detection port, the excess part of the cable is pushed to move by holding the surface of the cable. After moving it to one side of the positioning ring, the positioning ring can be pushed to expand outward until the cable completely enters the interior of the positioning ring. When the third spring is not under force, it restores its deformation and pushes the positioning ring to reset, thereby positioning the surface of the cable to prevent the excess part from being entangled.
