One end of the locking frame 91 is movably sleeved on the first rotating shaft 51, and the other end of the locking frame 91 is limited on the second rotating shaft 61 by a retaining spring 99. A second slider 93 is movably sleeved outside the first rotating shaft 51. The second slider 93 is slidably set in the locking frame 91, and the second slider 93 is connected to the locking frame 91 through a second spring 92. One end of the second spring 92 is fixedly connected to the locking frame 91, and the other end of the second spring 92 is fixedly connected to the second slider 93. The locking mechanism 2 includes a first slider 21. A block 22 and a rack 23 are provided on the first slider 21. The third gear 63 can mesh with the rack 23. The pushing mechanism 3 includes The wedge block 32, the inclined surface set on the wedge block 32 abuts against the inclined surface set on the first sliding block 21, the wedge block 32 is connected to the inner wall of the frame 1 through the first spring 31, one end of the first spring 31 is fixedly connected to the inner wall of the frame 1, and the other end of the first spring 31 is fixedly connected to the wedge block 32, one end of the second rotating shaft 61 is rotatably set in the frame 1, and the other end of the second rotating shaft 61 passes through the frame 1 and is connected with a spring block 62, the spring block 62 is fixedly connected to the second rotating shaft 61, and an anti-slip thread is arranged on the outside of the spring block 62, the first rotating shaft 51 is movably connected to the third reel 54 through the bearing 10, the inner ring of the bearing 10 is fixedly sleeved on the first rotating shaft 51, and the outer ring of the bearing 10 is fixedly connected to the third reel 54.
[0031] Specifically, the blade group 4 is composed of a plurality of blades, and the upper and lower ends are hard horizontal bars for fixing and connecting the first connecting rope 521, the second connecting rope 531 and the third connecting rope 541. The specific connection method and working principle are common knowledge known to the staff in this field, and will not be explained in detail here. Figure 3 The stopper 22 and the first slider 21 are integrally formed, and a rack 23 is provided on the first slider 21. The rack 23 is located on one side of the stopper 22. In the first stage, refer to Figures 1 to 5 When the third gear 63 is meshed with the front half of the first gear 7, the rotating adjustment mechanism 6 can make the third gear 63 drive the first rotating shaft 51 to rotate. Because the second slider 93 is abutted against the third connecting rope 541 opened on the third reel 54 under the elastic force of the second spring 92, the third reel 54 does not rotate with the first rotating shaft 51, so that the first reel 52 and the second reel 53 rotate. Since the way the first connecting rope 521 is wound around the first reel 52 is opposite to the way the second connecting rope 531 is wound around the second reel 53, when the first rotating shaft 51 rotates to drive the first connecting rope 521 to wind up, the second connecting rope 531 is in a line-releasing state, so that the blade group 4 is closed or opened. In the second stage, refer to Figure 3 and Figure 4 , press the adjusting mechanism 6 into the frame 1 by one notch, so that the third gear 63 is meshed with the rear half of the first gear 7, and the third gear 63 is meshed with the rack 23 and the locking mechanism 2 is pushed into the frame 1, so that the first slider 21 is in contact with the end of the wedge block 32. At this time, the first spring 31 is in a squeezed state. After the user lets go, under the elastic force of the first spring 31, the wedge block 32 pushes the first slider 21 to the left, and the rack 23 drives the third gear 63 to rotate, thereby causing the first rotating shaft 51 to rotate, realizing the normal closing of the blade group 4. At the same time, as the adjusting mechanism 6 moves into the frame 1, the locking frame 91 also moves backward on the first rotating shaft 51, and the second slider 93 in the locking frame 91 is still in contact with the third scroll 54 under the elastic force of the second spring 92, so that the third scroll 54 does not rotate with the rotation of the first rotating shaft 51; in the third stage, refer to Figure 4 and Figure 5 , the adjusting mechanism 6 is continued to be pressed so that the third gear 63 is meshed with the second gear 8. At this time, it can be known that the movement of the third gear 63 does not drive the first slider 21 to move, and the locking frame 91 continues to move inward with the second rotating shaft 61, and the locking frame 91 slides inward on the first rotating shaft 51, so that the second spring 92 is no longer compressed, and the second slider 93 no longer squeezes the third scroll 54. When the adjusting mechanism 6 is rotated, the third gear 63 drives the third scroll 54 to rotate, thereby completing the storage and unfolding of the blade group 4; if the state of the blade group 4 needs to be controlled, it is only necessary to control the position of the adjusting mechanism 6, refer to Figure 3 and Figure 5, two blocks 22 are respectively provided on the first slider 21. When entering the second stage from the first stage, the third gear 63 meshes with the rear half of the first gear 7 and continues to push the adjusting mechanism 6, so that the third gear 63 continues to slide on the rear half of the first gear 7, so that the third gear 63 drives the first slider 21 to move inward, so that the first slider 21 overcomes the elastic force of the first spring 31 and abuts against the end of the wedge block 32. After the user lets go, under the elastic force of the first spring 31, the wedge block 32 pushes the first slider 21 to the left. At this time, the third gear 63 rotates on the rack 23, so that the third gear 63 is located on the right half of the rack 23. When the adjusting mechanism 6 is continued to be pushed, the third gear 63 will not continue to move with the first slider 21, so that the third gear 63 can mesh with the second gear 8 alone. When the adjusting mechanism 6 is pulled back from the third stage to the first stage, the third gear 63 first meshes with the rack 23 and the first gear 7, and then the third gear 63 abuts against the stop block 22 to drive the stop block 22 to slide outward. When the stop block 22 abuts against the inner wall of the frame 1, the adjusting mechanism 6 will not be able to be pulled out further. The second rotating shaft 61 is rotated to make the third gear 63 rotate on the rack 23, so that the third gear 63 can continue to be pulled out after it disengages from the stop block 22, so that the third gear 63 can be pulled out further, so that the third gear 63 only meshes with the first gear 7, and the switching from the third stage to the first stage is successfully realized.
[0032] In this utility model, reference is made to Figures 1 to 5 When the adjusting mechanism 6 is in the first stage position, it is in the open state. When the adjusting mechanism 6 is pressed to the second stage, under the elastic force of the first spring 31, the blade group 4 is in the closed state. Conversely, when the adjusting mechanism 6 is in the first stage position, it is in the closed state. When the adjusting mechanism 6 is pressed to the second stage, under the elastic force of the first spring 31, the blade group 4 will be in the open state.
[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
