Embodiment Construction
[0018] The present invention will be further described below in conjunction with accompanying drawing:
[0019] A specific embodiment of the present invention is shown in the figure. All sealable guide thrust plates are designed to be the same, and are composed of push plate 1, slide plate 5 and "concave" shaped chute 6. Push plate 1 and slide plate 5 can move vertically in the horizontal plane; slide plate 5 can move along the adjacent push plate 1. Move in the direction of force; the vertical lower end surface of the tester is placed in the "concave" shaped groove 6, which is used for the guidance and bearing of the push plate 1, and makes there is a small gap between the push plate 1 and the test table surface. When assembling, all the push plates 1 slide plates protrude a part sequentially from the adjacent slide plates 5 .
[0020] After the push plate 1, the cross rib 2 and the slide plate groove 3 of the present invention are processed according to the drawings, the co...
