[0026] As Figures 1 to 8 shown, a volleyball marking rod includes a rod body 1, a sliding sleeve 3, a sliding card 4, a tightening mechanism 5, a sliding bowl 9 and a pressing mechanism 8.

[0027] A tightening mechanism 5 is fixedly arranged on the rod body 1. A thread is arranged at the middle position of the tightening mechanism 5. A sliding sleeve 3 is slidably arranged above the tightening mechanism 5. A limit ring 2 is fixedly arranged above the sliding sleeve 3. The limit ring 2 can prevent the sliding sleeve 3 from disengaging from the top end direction of the rod body 1.

[0028] A first card slot 301 for cooperating with the upper edge of the net is formed on the sliding sleeve 3. A sliding card 4 for cooperating with the upper edge of the net is slidably arranged in the first card slot 301. Convex stripes for cooperating with the net are arranged on the outer surface of the sliding card 4. The lower end of the sliding sleeve 3 is in threaded cooperation with the tightening mechanism 5, and the top end of the tightening mechanism 5 is in cooperation with the sliding card 4.

[0029] A grip 6 is fixedly arranged at the bottom end of the rod body 1. Convex stripes are arranged on the surface of the grip 6, which is convenient for rotating the rod body 1 through the grip 6.

[0030] A movable rod 7 is arranged at the bottom end of the grip 6. A sliding bowl 9 is arranged at the bottom end of the movable rod 7. A second card slot 901 for cooperating with the lower edge of the net is formed on the sliding bowl 9. A pressing mechanism 8 for cooperating with the lower edge of the net is arranged in the second card slot 901.

[0031] Specifically, the top end of the movable rod 7 is slidably connected to the bottom end of the grip 6. A limit block for cooperating with the grip 6 is arranged at the top end of the movable rod 7, and the limit block can prevent the movable rod 7 from disengaging from the bottom end of the grip 6.

[0032] The sliding bowl 9 is slidably arranged on the movable rod 7. A limit nut 10 is fixedly arranged at the bottom end of the movable rod 7. A regular hexagon groove for cooperating with the limit nut 10 is formed on the bottom surface of the sliding bowl 9. When the sliding bowl 9 is in cooperation with the limit nut 10, it can prevent the movable rod 7 from rotating, which is convenient for rotating the pressing mechanism 8.

[0033] The pressing mechanism 8 is in threaded cooperation with the movable rod 7. Convex stripes for cooperating with the net are arranged on the outer peripheral surface of the pressing mechanism 8.

[0034] The installation process of the present utility model is as follows:

[0035] Put the sliding sleeve 3 onto the upper edge of the net through the first card slot 301, rotate the grip 6, drive the tightening mechanism 5 to rotate through the rod body 1, and the tightening mechanism 5 is in threaded cooperation with the bottom end of the sliding sleeve 3, so as to push the sliding card 4 to move upward relative to the sliding sleeve 3 and clamp the net in cooperation with the first card slot 301;
