An upper support spring 510 is installed inside the upper sliding sleeve 59.

[0024] The top of the bottom support plate 51 is connected to the bottom of the lower anchor plate 3 through the bottom support spring 52. The bottom support rod 53 contacts the top of the lower anchor plate 3 through the outer bottom limit nut 54. The bottom support rod 53 passes through the lower anchor plate 3 and is connected to the bottom support plate 51 and the bottom limit nut 54 on the upper and lower sides of the lower anchor plate 3 respectively; When the bottom limit nut 54 rotates, it can drive the bottom support rod 53 to move up and down inside the lower anchor plate 3. When the bottom support rod 53 moves up and down, it can drive the bottom support plate 51 to move up and down.

Embodiment III

[0028] The difference from the above embodiment is as follows. Please refer to Figure 1 - Figure 10 The connection vibration mechanism 6 includes a support connecting rod 61 and a limit installation base 66. The limit installation base 66 is arranged at the center inside the anchor bolt perfusion cylinder 1. A bottom installation plate 62 is installed outside the support connecting rod 61. A middle installation plate 63 is installed outside the support connecting rod 61. A vibration connecting rod 64 is installed inside the middle installation plate 63. A limit installation block 65 is connected to the bottom of the bottom installation plate 62. An upper installation plate 67 is installed outside the support connecting rod 61. A vibration connection port 68 is installed at the top of the upper installation plate 67.

[0029] The support connecting rod 61 is inserted into the inside of the limit installation base 66 through the limit installation block 65 at the bottom of the bottom installation plate 62. The outer part of the limit installation block 65 is a frustum-shaped structure, and the outer part of the limit installation block 65 fits with the inside of the limit installation base 66. When the support connecting rod 61 moves downward, it can be inserted into the inside of the limit installation base 66 through the limit installation block 65 to install the support connecting rod 61 at the center of the anchor bolt pouring cylinder 1.

[0030] The vibration connecting rod 64 is of a bent structure. The vertical section of the vibration connecting rod 64 passes through the upper mounting plate 67, the middle mounting plate 63 and the bottom mounting plate 62. The horizontal section of the vibration connecting rod 64 is inserted into the inside of the lower support anchor cage 7. The outside of the vibration connecting rod 64 is movably connected to the bottom mounting plate 62 and the middle mounting plate 63, and the outside of the vibration connecting rod 64 is fixedly connected to the upper mounting plate 67; When the upper mounting plate 67 moves up and down, it can drive the vibration connecting rod 64 to move up and down. When the vibration connecting rod 64 moves up and down, it can drive the vibration connecting rod 64 to move up and down synchronously.

After the support connecting rod 61 is installed at the center of the anchor bolt pouring cylinder 1, continuously add concrete into the inside of the anchor bolt pouring cylinder 1. The concrete added into the anchor bolt pouring cylinder 1 needs to be fully vibrated before the texture of the concrete can be evenly mixed. Connect to an external vibration mechanism through the vibration connection port 68. After the external vibration mechanism is connected to the vibration connection port 68, it can drive the upper mounting plate 67 to vibrate up and down by a certain amplitude. When the upper mounting plate 67 moves up and down and vibrates, it can drive the vibration connecting rod 64 to move up and down and vibrate synchronously. The vibration connecting rod 64 not only passes through the center of the anchor bolt pouring cylinder 1 but also bends outward and is inserted into the inside of the lower support anchor cage 7 below the lower anchor plate 3. When the upper mounting plate 67 drives the vibration connecting rod 64 to vibrate inside the anchor bolt pouring cylinder 1, it can not only vibrate the concrete at the center of the anchor bolt pouring cylinder 1 but also fully vibrate the concrete below the lower anchor plate 3, enabling the overall concrete inside the anchor bolt pouring cylinder 1 to be evenly mixed, thereby preventing the overall strength of the anchor bolt from being reduced due to uneven texture of the concrete inside the anchor bolt pouring cylinder 1.
