[0021] The top of the pressure plate 122 is fixedly provided with a handle 123. The handle 123 is pulled upward to drive the bolt 121 to move upward and separate from the rotating disc 12. At this time, the rotating disc 12 can be rotated. The top of the anti-seismic block 1 is provided with a threaded hole. The threaded hole of the anti-seismic block 1 is in communication with the threaded hole of the nut 11. The threaded holes of the anti-seismic block 1 and the nut 11 are screwed with the bolts on the object. At this time, the first non-slip pad 13 is attached to the surface of the object to increase the friction between the anti-seismic block 1 and the object. The front side of the anti-seismic block 1 is provided with a first counterbore. The rear side of the first counterbore is provided with a first sliding groove. Two groups of second sliding grooves are uniformly provided on the left side of the first sliding groove. The left side of the second sliding groove is provided with a convex groove. The convex block 22 is slidingly arranged in the convex groove. The second sliding groove and the threaded hole of the anti-seismic block 1 are in communication and provided with a receiving groove.

The second non-slip pad 14 is located in the receiving groove and the threaded hole of the anti-seismic block 1. When the inner threaded sliding block 21 drives the second non-slip pad 14 to move into the receiving groove, the anti-seismic block 1 and the nut 11 can be screwed with the external bolts. The rotating disc 12 is rotationally arranged in the first counterbore. The pressure plate 122 and the handle 123 are slidingly arranged in the second counterbore.

The cross screwdriver is inserted into the cross recess and counterclockwise rotated to drive the rotating disc 12 to rotate counterclockwise. The rotating disc 12 drives the two groups of inner threaded sliding blocks 21 to move outward synchronously through the two-way screw rod 2 to drive the second non-slip pad 14 to move into the receiving groove. Then the threaded holes of the anti-seismic block 1 and the nut 11 are screwed with the bolts on the object. At this time, the first non-slip pad 13 is attached to the surface of the object to increase the friction between the anti-seismic block 1 and the object. When the anti-seismic block 1 and the nut 11 are screwed with the bolts on the object and tightened, the two groups of second non-slip pads 14 are slid out of the receiving groove by rotating the rotating disc 12 clockwise to tightly attach to the bolts on the object to increase the friction between the anti-seismic block 1 and the bolts.

At the same time, when the insertion hole of the rotating disc 12 is aligned with the bolt 121, the handle 123 is released. At this time, the spring 124 utilizes its own resilience to drive the bolt 121 to insert into the insertion hole through the pressure plate 122 to lock the rotating disc 12, thereby achieving the effect of locking the position of the second non-slip pad 14. Moreover, the magnetic attraction force of the magnetic block 125 and the iron block 126 can improve the insertion stability of the bolt 121 to ensure the use reliability of the entire nut.
