Spacer installer

The invention discloses a spacer installer, which comprises a rod sleeve, a rod body, a clamp, a clamp rotation regulator, a screw rod and a screw sleeve, the rod body is arranged in the rod sleeve in a sliding manner; the screw rod is arranged in the rod body and the rod sleeve; the screw sleeve is in threaded connection with the screw rod; the screw sleeve is used for driving the rod body to move along the axial direction of the screw rod when the screw rod rotates; the clamp is rotatably arranged on the rod body; and the clamp rotation adjuster is used for driving the clamp to rotate according to the movement of the screw sleeve. By arranging the screw sleeve to be matched with the screw rod, after the installer penetrates through a construction hole of the spacer, the screw sleeve moves close to the rod body, the clamping apparatus is influenced by the clamping apparatus rotation adjuster to change from longitudinal rotation to transverse rotation so as to clamp the construction hole of the spacer, the cl
