Further, the force application structure include spring, holding screw, correspondingly, the screw has been attacked on the steel ball slotted hole inner wall, and holding screw spiro union is in the steel ball slotted hole, the one end and the holding screw connection of spring, the other end and the steel ball of spring are connected.

Further, the spring is a compression spring.

And screwing the set screw to a certain position of the steel ball slotted hole, so that the steel ball extends out of the steel ball slotted hole in a natural state, the steel ball is partially positioned in the limiting hole, and the outermost edge of the steel ball is positioned between the inner wall and the outer wall of the limiting column along the orientation direction of the set screw. Because the steel ball is matched with the limiting hole, the whole rotating handle can be fixedly positioned at a position which is 90 degrees in the horizontal direction.

During the use, only punch on the structure that needs are opened, are closed, afterwards, with the screw in rotatory stop gear's screw, fix rotatory stop gear on the structure that needs are opened, are closed. When the handle is installed, the direction of the limiting hole is noticed, so that the rotating handle can clamp the two structural members, and the relative movement of the structural members is limited.

Compared with the prior art, the utility model discloses a technical scheme has following beneficial effect: compared with the prior fixing piece of a thread fastening type, the fixing piece of the opening and closing structure of the case is simple and reliable to operate, the opening and closing structure of the case is more convenient to fix and release, and in addition, only one structural piece needs to be perforated, so that the original structure of the case is favorably stabilized.

Detailed Description

The following description of the embodiments of the present invention is provided with the accompanying drawings, and the purpose of the disclosed embodiments is to explain and explain the present invention, rather than to limit the present invention, and all technical solutions obtained by simple replacement, combination and development on the basis of the present invention should fall into the protection scope of the present invention.

Example one

A rotary limiting mechanism comprises a limiting column 1 and a rotary handle 2; spacing post 1 is hollow cylinder, 1 bottom of spacing post is along radial outside oblate column step, it has the screw thread to attack on the 1 inner wall of spacing post, 2 one ends of swing handle are equipped with the trompil, spacing post 1 embolias downthehole, swing handle 2 is equipped with the oblate column step top surface contact of the bottom surface of trompil one end and spacing post 1 bottom, spacing post 1 and swing handle 2 clearance fit, spacing post 1 and swing handle 2 have 90 rotatory limit structure of level simultaneously within a definite time, swing handle 2 is 90 rotatory around spacing post 1.

Spacing post 1 and rotatory handle 2 within a definite time horizontal 90 rotatory limit structure include on the spacing post 1 two be 90 spacing holes 1.1 that set up in the horizontal direction to and the pearl structure that bumps that sets up in the handle 2 soon, bump pearl structure and spacing hole 1.1 combined action, form horizontal 90 rotatory spacing.
