[0027] Working principle: When the present invention is in use, the two groups of first steel plates 4 and second steel plates 7 are respectively close to the positioning blocks 803 on the outer walls of the first restraint frame 1 and the second restraint frame 2, so that the engaging grooves 804 on the first steel plates 4 and the second steel plates 7 are inserted outside the positioning blocks 803, and the clamping blocks 806 on both sides of the positioning blocks 803 are squeezed. After the clamping blocks 806 are squeezed, the second springs 805 on one side are squeezed and received inside the positioning blocks 803, so that the first steel plates 4 and the second steel plates 7 are inserted to the bottom of the positioning blocks 803 and squeeze the first springs 802. At the same time, the clamping blocks 806 pop out to the outside under the elastic support of the second springs 805 and return to their original positions, so as to be clamped on the tops of the first steel plates 4 and the second steel plates 7, so that the first steel plates 4 and the second steel plates 7 are clamped between the clamping blocks 806, the mounting plate 801 and the first springs 802, and further the first steel plates 4 and the second steel plates 7 are fixed to the outer walls of the first restraint frame 1 and the second restraint frame 2. The operation is simple and the installation is rapid. If the first steel plates 4 and the second steel plates 7 need to be horizontally fixed, then push the moving block 809 to move on the first steel plate 4 through the bottom slider and the chute 807.
