For convenience of understanding, the principle of operation of the synchronous opening and closing device provided by the present embodiment is as follows:

two sections of external threads with different rotation directions are processed on the same upper rod 11 or the same lower rod 21, an upper shifting block 13 or a lower shifting block 23 is respectively arranged on the two sections of the external threads, and when the upper rod 11 or the lower rod 21 starts to rotate, the two upper shifting blocks 13 or the lower shifting blocks 23 can move in the opposite direction or in the opposite direction. When the upper support frame 12 or the lower support frame 22 is pushed by the pushing driver, the upper dial 18 or the lower dial 28 can be located outside or inside the chuck of the hanger 100, and when the rotating driver 31 drives the rotating rod to rotate by the chain transmission, the rotating rod drives the upper rod 11 or the lower rod 21 to rotate by the orthogonal bevel gear set, and the upper dial 13 or the lower dial 23 starts to move in different directions, so that the upper dial 18 or the lower dial 28 pushes the upper chuck 101 or the lower chuck 102 to move towards or away from each other. That is, the opening and closing of the clip of the hanger 100 can be achieved by controlling the forward and reverse rotation of the rotary actuator 31, and the size of the opening and closing is controlled by the encoder mounted on the upper bar 11 or the lower bar 21.

It should be noted that the foregoing is only a preferred embodiment of the present invention and the technical principles applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious modifications, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention. Therefore, although the present invention has been described in greater detail with reference to the above embodiments, the present invention is not limited to the above embodiments, and may include other equivalent embodiments without departing from the scope of the present invention.
