  • Patent number: 7662046
    Abstract: An improved clamping fixture for bouncing apparatus to clamp two ends of a resilient stem of a bouncing apparatus includes two coupling members and two anchor members. The two coupling members are made from plastics and have respectively a first latch member and a second latch member to form a clamping space, and anchor bosses on two outer sides pivotally engageable with the anchor members. The two coupling members have coupling forces to clamp the two ends of the resilient stem, and the two anchor members are coupled on the upper end and lower end of the bouncing apparatus. The resilient stem can be positioned securely at two ends of the bouncing apparatus to facilitate bouncing operation without being scraped, damaged or fractured. Durability is greater.
