Doing warm-up activities is precisely to increase the excitement of the large cortical nerve cells. Warming-up activities can also slightly increase the body temperature, so that the muscles and tendons are in a good state, with good elasticity and stretchability, so that they will not be strained due to sudden contraction Or tearing, which is especially important in winter. At present, when using sports equipment such as a basketball stand, it is often necessary to lift it accordingly to make it reach the standard shooting height. The current lifting and locking mechanism has a complex structure and low performance
