Further, a plurality of shells are fixedly connected to the upper support plate and the lower support plate respectively, a first cavity and a second cavity are formed in the shells, the upper support plate and the lower support plate respectively, and the springs are wound on the connecting columns, and two ends of the springs are arranged in the first cavity and the second cavity respectively.

Furthermore, the connecting column is of a hollow structure, and sealing covers are respectively arranged on two sides of the connecting column.

Due to the adoption of the technical scheme, the utility model has the beneficial effects that:

1. The knee joint protector adopts a Y-shaped structure, and is provided with the air bags aiming at the lower side and the peripheral side of the knee, and the front side of the thigh is exposed, so that compared with the knee joint protector with a full sleeve, the knee joint protector is cooler and cooler due to the exposure of the skin.

2. The spring of the knee joint protector is matched with the upper support plate and the lower support plate, and when the knee joint protector is used for bending a leg, the spring generates acting force, so that the upper support plate and the lower support plate are not close to each other, a user can feel the reaction force of the upper support plate and the lower support plate, the user can pay attention to the leg, and the bending amplitude of the leg is reduced or the leg is not bent.
