Summary: | The utility model discloses a wooded stand suitable for being installed on a ceiling; the back of a common wooded stand is provided with two V-shaped (or fade down) blocks, a movable flat plate whose middle is provided with a bolt hole, or a tightly buckled device composed of an elliptical (or rhombic) loop; the wooded stand is fixed to the ceiling through the expansion and the deformation of the tightly buckled device. As the wooded stand is used, the frequent labor of an electrical installation worker for fixing the wooded stand to the ceiling can be relieved; the utility model has the advantages of labor saving, efficiency enhancing, convenient assembly and disassembly, and the enhancement of the fastness of the wooded stand. |
