All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples:

referring to fig. 1-5, a novel out-opening handle includes:

The base cover plate 1 is a cuboid plate with an opening on one side;

the fixing piece 2 is arranged in the base cover plate 1 in a fitting way;

The handle 3 is arranged on the outer side of the base cover plate 1;

The square shaft 4 penetrates through the fixing piece 2 and the base cover plate 1 in a rotating mode, and one end of the square shaft 4 is detachably fixed with one end of the handle 3;

the rotary pin 5 is fixedly arranged at one end of the handle 3 and is rotationally connected with the outer side surface of the base cover plate 1;

the circular arc track 21, circular arc track 21 is offered on mounting 2, and the one end cover of round pin 5 is established in circular arc track 21's inside.

As can be seen from the above, in the present application, the handles 3 mounted on both sides of the profile are connected through the square shaft 4, so that the two handles 3 can be rotated synchronously, wherein the square shaft 4 is a connecting member for connecting the handles 3 mounted on both sides of the profile, and since the square shaft 4 rotates to penetrate the fixing member 2 and the base cover plate 1 and one end of the square shaft is detachably fixed with one end of the handle 3, when the handles 3 are rotated, the square shaft 4 can be driven to rotate, and the rotating pin 5 can be arranged to rotate around the square shaft 4 along with the rotation of the handles 3, and the rotating angle of the rotating pin 5 can be limited due to the arrangement of the circular arc track 21, thereby limiting the rotating angle of the handles 3.

Those skilled in the art will recognize from the drawings that only a portion of the structure of the out-opening handle is shown in the drawings for the purpose of describing the features of the present application.

Specifically, as can be seen from fig. 3 and 4, the base cover plate 1 is provided with a shaft hole 11, the fixing member 2 is rotatably provided with a square hole pin 23, one end of the square hole pin 23 is sleeved with the shaft hole 11, and the inner hole of the square hole pin is matched and spliced with the square shaft 4.

As described above, the square shaft 4 can be controlled to rotate by the handle 3 by providing the shaft hole 11 and the square hole pin 23.
