The upper end of the insertion type anchor is detachably connected with the lower end of the vertical installation rod 100, and the outer expansion driving member is connected in the insertion type anchor. The specific structure of the insertion type anchor in the embodiment is that the insertion type anchor comprises a connecting joint 201 and an anchoring rod 202, the axis of the connecting joint 201 and the axis of the anchoring rod 202 coincide, and a transition guide head 203 is formed at the lower end of the anchoring rod 202. A first connecting flange 207 is configured at the upper end of the connecting joint 201, and the anchoring rod 202 is configured at the lower end of the connecting joint 201, the radial length of the anchoring rod 202 is tapered downward along the vertical direction, and a driving cavity is configured in the anchoring rod 202. A plurality of slits 205 are uniformly opened on the anchoring rod 202 along the circumferential direction, each slit 205 extends upward from the lower end of the anchoring rod 202, and the slits 205 are communicated with the driving cavity, and the lower end of the outer expansion driving member extends out of the lower end of the anchoring rod 202 through the driving cavity. The specific structure of the outer expansion driving member in the embodiment is that the outer expansion driving member comprises a driving rod 210, a threaded rod 209, an adapter rod 208 and an operating head 211, and the axes of the four coincide.
