Circular sliding holes are symmetrically opened on the left and right sides of the cylindrical seat 4, and a strip sliding hole 6 is opened at the bottom of the cylindrical seat 4.

[0024] Furthermore, the protection mechanism 7 includes a protection sheet 711, which is arranged inside the cylindrical seat 4, a screw rod 712 is rotatably connected to the middle of the outer side of the protection sheet 711, and slide rods 713 are symmetrically arranged on the left and right sides of the screw rod 712, and a slide sheet 714 is equidistantly fixedly connected to the bottom of the protection sheet 711;

[0025] There are four protective sheets 711, which are arranged in a circle inside the cylindrical seat 4. A rubber gasket is arranged on the inner side of the protective sheet 711. The screw rod 712 is threadedly connected to the inside of the threaded tube 5. The screw rod 712 is inserted into the circular sliding holes on the left and right sides of the threaded tube 5. The sliding sheet 714 is slidably connected to the inside of the protective mechanism 7. The bottom of the sliding sheet 714 is attached to the top of the bottom fitting disk 1. The outer end of the screw rod 712 is provided with a hexagonal block for easy rotation.

[0026] It should be noted that when protecting the concrete base, the bottom bonding plate 1 is fixed to the bottom of the concrete base, and the hexagonal block on the outside of the screw rod 712 is rotated by a tool to drive the screw rod 712 to rotate.

The fastening ring 911 is threadedly connected to the top of the cylindrical seat 4 through the inner internal thread groove 913.

[0029] It should be noted that after completing the protective treatment of the concrete base, release the fixing of the fastening ring 911 by the pin 912, put the fastening ring 911 on the top of the cylindrical seat 4, connect the fastening ring 911 together through the pin 912, rotate the fastening ring 911, and fix the fastening ring 911 on the top of the cylindrical seat 4 through the threaded connection of the internal thread groove 913 on the inner side of the fastening ring 911, so as to further fasten the cylindrical seat 4 and avoid the failure of the protective mechanism 7 caused by the separation of the cylindrical seat 4. The handle 914 arranged on the outside of the fastening ring 911 is convenient for the operator to rotate the fastening ring 911, so as to facilitate the installation of the fastening mechanism 9.

[0030] Working principle: When the concrete base is subjected to auxiliary anti-crack treatment, a hole corresponding to the socket 11 is opened at the bottom of the concrete base, the screw on the right side of the bottom fitting disk 1 is loosened, the bottom fitting disk 1 is rotated, and the bottom fitting disk 1 is sleeved on the surface of the concrete base, and then the plug rod 2 is nailed into the hole corresponding to the socket 11, and the screw on the right side of the bottom fitting disk 1 is tightened to complete the fixation of the bottom fitting disk 1. The hexagonal block on the outside of the screw rod 712 is rotated by a tool to drive the screw rod 712 to rotate. At the same time, under the connection of the threaded tube 5, the screw rod 712 drives the protective sheet 711 to fit on the surface of the concrete base, thereby reducing the vibration of the concrete. The rubber gasket arranged on the inner side of the protective sheet 711 can increase the fitting effect of the protective sheet 711 and seal the surface of the concrete base at the same time to prevent erosion by rainwater. The sliding pieces 714 on the left and right sides and the bottom of 712 can not only limit the movement of the protective sheet 711, but also increase the fit of the protective sheet 711, prevent the protective sheet 711 from shaking up and down, and increase the protective effect. After completing the protective treatment of the concrete base, release the fixing of the fastening ring 911 by the pin 912, and put the fastening ring 911 on the top of the cylindrical seat 4. After connecting the fastening ring 911 together through the pin 912, rotate the fastening ring 911, and fix the fastening ring 911 on the top of the cylindrical seat 4 under the threaded connection of the internal thread groove 913 on the inner side of the fastening ring 911, so as to further fasten the cylindrical seat 4 and prevent the separation of the cylindrical seat 4 from causing the protection mechanism 7 to fail. The handle 914 arranged on the outside of the fastening ring 911 is convenient for the operator to rotate the fastening ring 911, so as to facilitate the installation of the fastening mechanism 9.
