Abstract
The utility model discloses a high-elasticity elastic sheet which comprises the following components: a welding plane, a U-shaped bent part which is formed through upward bending from one end of the welding plane, an absorbing plane which is obtained through extending from the U-shaped bent part, and a contact part which is formed through upward extending from the absorbing plane. Two sides of the welding plane are symmetrically provided with two clamping plates which extend to two sides of the contact part. The height of each clamping plate is smaller than that of the contact part. Elastic legs extend from the two sides of the contact part, which are next to the clamping plate. One end of the elastic leg is connected with the contact part, and the other end elastically abuts against one side of the clamping board, which is next to the contact part. Through arranging the elastic legs which elastically abut against the clamping plates at two sides of the contact part, the contact elastic force of the contact part is enlarged, and the elastic force is more uniform, thereby ensuring original elastic force of the contact part after long-time repeated use, effectively preventing excessive pressing of the contact part and preventing deformation damage of the elastic sheet.
