When the handle part 130 is located at the opening position, the notch 128 formed at the edge of the pin hole 126 and the limiting protrusion formed at the end of the pin shaft 134 are away from each other, and in this embodiment, the included angle between the two is 90 °. The absence of the notch 128 provides a shield for the stop tab to limit the removal of the handle member 130 from the end wall 124.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
