[0025] Further, such as Figure 2 and Figure 3 As shown, the connecting component 4 also includes grooves 42 and fixed columns 43. The multiple grooves 42 are respectively opened on the rotating ring 41 and the four sliders 45. The rotating ring 41 is provided with four grooves 42. The grooves 42 are distributed in a circular array with the center of the rotating ring 41 as the center. The multiple fixed columns 43 are respectively fixedly connected to the multiple grooves 42. One groove 42 corresponds to one fixed column 43. The width of the rotating rod 44 is equal to the width of the groove 42. The two ends of the four rotating rods 44 are respectively rotatably connected to the multiple fixed columns 43.

[0026] Further, such as Figure 1 and Figure 2As shown, the fixing assembly 5 includes a slide groove 51 and a rack 52. Four slide grooves 51 are respectively opened on the mounting plate 46. The slide grooves 51 are distributed in a circular array with the center of the mounting plate 46 as the center. A plurality of racks 52 are respectively fixedly connected to the four slide grooves 51. Two racks 52 are arranged in one slide groove 51, and the two racks 52 are respectively located on both sides of the slide groove 51.

[0027] Further, such as Figure 1-Figure 4 As shown, the fixing assembly 5 also includes adjusting bolts 53 and connecting blocks 54. The four adjusting bolts 53 are respectively threadedly connected to the four sliders 45. The four connecting blocks 54 are respectively rotatably connected to the four adjusting bolts 53. The length of the connecting blocks 54 is equal to the inner wall length of the sliding shell 55.

[0028] Further, such as Figure 2-Figure 4 As shown, the fixed assembly 5 also includes a sliding shell 55, and the four sliding shells 55 are respectively fixedly connected to the four sliders 45, and the four sliding shells 55 are respectively slidably connected in the four sliding grooves 51.

The nut 3 moves toward the direction of the mounting plate 46 while rotating, driving the rotating ring 41 to move. Since the rotating rod 44 is rotatably connected to the rotating ring 41, the rotating ring 41 pushes the rotating rod 44 to rotate, and the slider 45 moves accordingly. When the rotating ring 41 moves to fit with the mounting plate 46, the rotation of the nut 3 is stopped, and the adjusting bolt 53 is rotated at this time. The adjusting bolt 53 moves toward the direction of the sliding shell 55, driving the connecting block 54 to move. Since the clamping block 56 is slidably connected to the connecting block 54, the connecting block 54 will push the clamping block 56 to move outward, and push the tooth block 57 out of the sliding shell 55. When the tooth block 57 is engaged with the rack 52, the fixing of the sliding shell 55 is completed. At this time, the rotating ring 41 and the nut 3 are both fixed, making the device more stable.
