When using the vaulting pole, utilize the edge of mounting groove 33 as supporting basis and wall butt, can avoid connecting piece 32 and wall contact, played the guard action to connecting piece 32.
Meanwhile, in order to facilitate the user to install the stay bar between two walls, in the present embodiment, the suction cups 34 are provided around the installation grooves 33 on the side walls of the connector 3 away from the connecting cylinder 31. Specifically, the suction cup 34 may be made of rubber, and the suction cup 34 is formed by rubber surrounding the mounting groove 33. When the vaulting pole is installed, can adsorb on a wall body through sucking disc 34 earlier connector 3, make interior body of rod 2 and outer body of rod 1 follow connecting cylinder 31 and hang down naturally, the user holds up outer body of rod 1 again, to horizontal position, and adjust the length that interior body of rod 2 stretches out outer body of rod 1, make outer body of rod 1 support tight opposite side wall body, need not the user and adjust the whole length of vaulting pole simultaneously with outer body of rod 1 in adjusting, and make the vaulting pole both ends paste the wall surface flatly simultaneously, the vaulting pole installation is more convenient.
Further, can also set up air level 13 on the body of the outer rod 1, the user can accurately judge whether current vaulting pole is in the level through observing air level 13, improves the installation stationarity of vaulting pole.
It should be apparent to those skilled in the art that while the preferred embodiments of the present invention have been described, additional variations and modifications in these embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the following appended claims be interpreted as including preferred embodiments and all such alterations and modifications as fall within the scope of the invention.
