Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. For example, based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

Please refer to Figures 1-4, the utility model provides a technical solution, a volleyball smash training device for physical education, including a mobile platform 1, which increases the gravity at the bottom of the mobile platform 1 through the counterweight iron block, thereby improving the mobile platform. 1. The firmness of the placement can prevent the mobile platform 1 from bumping and toppling during use and cause injury to the trainer. It is safe to use. The bottom of the mobile platform 1 is equipped with a counterweight iron block, and the outer part of the counterweight iron block is fixed with rubber ring, the middle part of the top of the mobile platform 1 is equipped with a fixed rod 2, the top of the fixed rod 2 is equipped with a telescopic rod 3, and the top of the telescopic rod 3 is sleeved with a clamping rod 4, in order to disassemble and maintain the clamping rod 4 after long-term use.
