Referring to FIG. 1 , the first connecting surface 322 is disposed above the connecting portion 32 of the leg 3 , and the second connecting surface 323 is defined at the lower portion. The connecting portion 32 defines six uniformly disposed through connecting portions 322 and the first portion. The receiving hole 3221 of the connecting surface 323 of the second connecting surface 323, wherein the receiving hole 3221 corresponding to the rising portion 621 of the second extending portion 62 of the elastic piece 6 accommodates the ball 3222, and when the rising portion 621 is in a natural state, The above-mentioned ball 3222 is jacked up and partially protruded. The receiving holes 3221 are six in this embodiment, and they may be an even number of four or more. The connecting portion 22 of the leg 2 is composed of three parts, including an intermediate portion 223 and a lower pad 224 under the intermediate portion 223 and an upper pad 225 above the intermediate portion 223. The intermediate portion 223 has a fixing hole 2231 in the upper and lower portions. A fixing post 2251 extends upwardly from the upper pad 225, and a fixing post 2241 extends upwardly. The fixing posts 2241 and 2251 can be fixed to the fixing hole 2231. A receiving hole 2242 is formed on the lower pad 224 corresponding to the receiving hole 3221, and the upper pad 225 is There is also a receiving hole 2252 which is evenly disposed. The upper surface of the upper pad 225 is the first connecting surface 2253, and the lower surface of the lower pad 224 is the second connecting surface 2243. The second connecting surface 123 of the connecting portion 12 of the leg 1 has a receiving hole 1122 corresponding to the receiving hole 2252. A concave portion 124 is formed on the first connecting surface 122 of the connecting portion 12, and the elastic portion 7 is received in the concave portion 124. The elastic piece 7 corresponds to the elastic piece 6 and has a first extending portion 71 and a second extending portion 72 thereon. The first extending portion 71 corresponds to the second extending portion 62, the second extending portion 72 is disposed corresponding to the first extending portion 61, and the second extending portion 72 has a rising portion 721 thereon. A ball 1123 is housed in the receiving hole 1122 corresponding to the rising portion 721.

Referring to Fig. 2, a pressure plate 8 is disposed above the elastic piece 7, and three press posts 82 are protruded corresponding to the first extending portion 71 to be coupled to the elastic piece 7. A recess 324 is formed in the second connecting surface 323 of the leg 3 to accommodate the elastic sheet 6 and the receiving tray 5.

In the above embodiment, although the connecting portion 32 of the leg 2 is composed of three portions, it is of course possible to integrally provide the intermediate portion 223, the lower pad 224 and the upper pad 225. The above elastic sheets 6, 7 and the beads 3222, 1123 form two sets of elastic bodies, but the elastic body can also be composed of other similar manners.
