Referring to fig. 4 and 5, the inner rod 2 is slidably connected inside the outer shell 1, and the inner rod 2 is matched with the inner size of the outer shell 1. A plurality of mounting grooves 21 are opened to the circumference lateral wall of interior pole 2, and a plurality of mounting grooves 21 are around the axis evenly distributed of interior pole 2. A shaft rod 22 is fixed in the mounting groove 21, and the length direction of the shaft rod 22 is perpendicular to the length direction of the inner rod 2. The inner rod 2 is rotatably connected with a reinforcing rod 23 through each shaft rod 22. The anchor strut 23 is equipped with connecting plate 231, and the shaft hole has been seted up to connecting plate 231, and every connecting plate 231 all carries out the rotation through shaft hole and the axostylus axostyle 22 that corresponds and is connected. In addition, one end of the connection plate 231 located in the installation groove 21 is provided with a segment of arc surface so that the reinforcing bar 23 can rotate in the installation groove 21.
Correspondingly, a plurality of avoiding grooves 3 are formed in the shell 1, and each reinforcing rod 23 is arranged in the corresponding avoiding groove 3. The avoiding groove 3 comprises a bottom groove wall 31 and a top groove wall 32 which are opposite, the plane where the bottom groove wall 31 is located is perpendicular to the axis of the shell 1, the top groove wall 32 is an arc surface, the distance between the top groove wall 32 and the bottom groove wall 31 is gradually reduced along the direction close to the outer peripheral surface of the shell 1, one end, abutted against the bottom groove wall 31, of the reinforcing rod 23 is an abutting surface 232, and the abutting surface 232 is an arc surface, so that the reinforcing rod 23 can penetrate out of or retract into the storage groove conveniently.
In order to limit the movement of the inner rod 2 relative to the shell 1, four limiting grooves 14 are formed in one end, close to the opening surface, of the interior of the shell 1, and the four limiting grooves 14 are uniformly distributed around the axis of the shell 1. The length direction of the limiting groove 14 is parallel to the axial direction of the inner rod 2 and the shell 1, and the limiting groove 14 is not communicated with the outside of the shell 1.
Correspondingly, when interior pole 2 is kept away from the fixed stopper 24 that is provided with the adaptation with spacing groove 14 of shell 1's one end, when stopper 24 is located the bottom of spacing groove 14, interior pole 2 is located shell 1 inside completely and every stiffener 23 and wears out in shell 1 outside by dodging groove 3, and when stopper 24 was located the top of spacing groove 14, every stiffener 23 all was located and dodges inside groove 3, and interior pole 2 top is equipped with control unit.
