The present invention relates to an anchor to be fixed, and more specifically, to an anchor to be fixed, comprises a housing and a piston. The housing functioning as a cylinder has an open part formed therein. A piston has wings mounted thereon to be inserted into the open part. When the piston is inserted into the housing and pulled, the wings inserted into the open part are structurally unfolded at a predetermined angle to increase the surface area where the wings are in contact with the ground and increase frictional force, thereby firmly fixing the anchor on the ground. Moreover, a tip is automatically or artificially exploded after the anchor is stuck in the ground such that the tip is deformed, thereby increasing the surface area where the tip is in contact with the ground and frictional force, or a spiral part mounted on the body of an anchor is in contact with the ground after the anchor is stuck in the ground, thereby firmly fixing the anchor to the ground. The housing has the tip facing the ground at one side end closed and the other side end partially opened with a slide hole and a hollow hole formed on the interior thereof to function as a cylinder. The piston has a body, a connection part and a protrusion part. The body has a length shorter than the length of the hollow hole to be inserted into and slid in the hollow hole and has one side end arranged in the direction of the tip. The connection part is connected to the other end of the body and performs linear movement through the slide hole to be inserted into the housing or exposed to the outside of the housing. The protrusion part is connected to the connection part to be exposed to the outside of the housing and has a diameter larger than the slide hole. |
