In the preferred embodiment, as shown in fig. 2 and 3, the other end of the swing link 34 is connected to the transmission 5. With this structure, the swing motion of the swing link 34 is achieved.
In the preferred scheme, as shown in fig. 1 and 2, a limiting block 31 is arranged on the swing rod 34 near the end of the sliding rod 33, in this example, the limiting block 31 is a nut, threads are arranged on the end of the swing rod 34, the limiting block 31 is fixedly arranged on the end of the swing rod 34 in a double-nut mode, and a second reset spring 32 is arranged between the sliding rod 33 and the limiting block 31; with this structure, the slide bar 33 can slide along the swing bar 34.
In the preferred scheme, as shown in fig. 1 and 2, the sliding rod 33 slides along the guide rail, and the guide rail at least comprises a first guide rail section 35 and a second guide rail section 36, wherein the first guide rail section 35 is a curve with equal radius, the second guide rail section 36 is a curve with radius tending to increase, and the center of the first guide rail section 35 is the swing center of the swing rod 34. With this structure, during the swing of the swing lever 34, the slide bar 33 slides along the guide rail; and guided by the second guide rail section 36, the slide bar 33 also slides along the swing rod 34 and gradually moves away from the swing center of the swing rod 34, so that the adsorption device 2 is separated from the music page in a near relative translation manner, and the adsorption device 2 cannot influence the music page in the process that the swing rod 34 drives the adsorption device 2 to return to the left side of the bracket 1. The starting point between the second guide rail section 36 and the first guide rail section 35 is located at a position exceeding 1/2 of the entire swing stroke of the swing lever 34, so as to avoid the adsorption device 2 from being separated from the music page prematurely, thereby causing page turning failure, as shown in fig. 2. In the process that the slide bar 33 slides along the swing rod 34, when the suction device 2 adopting the negative pressure suction mode is adopted, air can gradually enter between the suction device 2 and the music page, so that the suction device 2 and the music page are easy to separate.
