Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses a stop device, including stopper 1 and spacing compoboard, as shown in fig. 2, stopper 1 cup joints in the outside of square pivot 2, stopper 1 is including arc post 3, trapezoidal post 4 and the rectangle post 5 that from top to bottom connects gradually, the outer fringe cross-section of arc post 3 is circular-arcly, the radian of 3 cross sections of arc post is greater than 270 and is less than 360, preferably, the radian of arc post cross section is less than 300.

The upper base of trapezoidal post 4 is connected with arc post 3, the lower bottom of trapezoidal post 4 is connected with rectangle post 5, the length of the upper base of trapezoidal post 4 is greater than the length of going to the bottom, arc post 3 runs through along the fore-and-aft direction and is equipped with spacing hole 6, the cross-section of spacing hole 6 is the rectangle, four angles of spacing hole 6 are equipped with chamfer groove 7, the cross-section of chamfer groove 7 is the arc, and chamfer groove 7 and square pivot 2 have certain rotation allowance each other, and revolution mechanic is difficult for wearing and tearing.

As shown in fig. 1, the limiting combination plates are symmetrically distributed on two sides of the square rotating shaft 2, each limiting combination plate comprises a connecting plate 8 and a plurality of baffles 9, the connecting plate 8 extends along the length direction of the square rotating shaft 2, the plurality of baffles 9 are arranged on the outer side of the connecting plate 8, the baffles 9 are vertically connected with the connecting plate 8, a blocking groove 10 is arranged on the inner side of the upper end of each baffle 9, and the blocking groove 10 limits the rotation range of the rectangular column 5.
