Three ball heads are installed in the clamps. A mirror reflector block is fixed to one side of each ball head. The reflective surface of the mirror reflector block faces the observation port of the total station. A fastening bolt is screwed to one side of each ball head on the clamp. The tail end of the fastening bolt abuts against the ball head.

[0007] The pointed rod includes an inverted conical tip and a cylindrical first rod body. The tip is fixed to the bottom end of the first rod body, and a hexagonal prism-shaped first socket is provided at the top center of the first rod body.

[0008] The standard rod has a downward-protruding hexagonal prism-shaped first connecting post at its bottom end and a hexagonal prism-shaped second receiving slot at the center of its top.

A downward-protruding hexagonal prism-shaped second connecting post is provided at the center of the bottom end of the second rod body. The second connecting post is plugged into a second socket. The second connecting post is connected to the standard rod with a set screw.

[0010] The clamp includes two semi-cylindrical clamping blocks connected by a semi-threaded bolt. Each clamping block has three evenly distributed ball-head hinge semi-grooves on its flat side. Two ball-head hinge semi-grooves at the same height are joined together to form a ball-head hinge groove. The ball head is installed in the ball-head hinge groove. The fastening bolt is screwed onto one of the clamping blocks. A semi-circular connecting block is fixed to the bottom of each clamping block. The connecting block has two arc-shaped holes. The connecting block is connected to the mounting flange by a hexagonal head bolt and a hexagonal nut. The hexagonal head bolt is inserted into the connected arc-shaped hole and the round hole.
