Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of laser levelers, and more specifically to a fixing device of a laser leveler with a central screw hole. Background Art
[0002] The laser level currently used for decoration is a laser level with a central screw hole. Its fixing bracket includes a wall bracket for fixing the laser level on the wall, and a beam bracket for fixing the laser level on the beam. Sometimes it is necessary to build a wall in the middle of the house where there is no beam. The laser level fixed by the above fixing bracket cannot find a 90-degree wall-building angle for wall-building. So some people use lifting rods to fix the laser level so as to find a 90-degree wall-building angle in the place where there is no beam. However, since the lifting rods occupy the ground space, it is inconvenient to build stairs when building walls. Utility Model Content
[0003] The utility model aims to provide a laser level fixing device with a central screw hole, which has a simple structure and can fix the laser level on a roof without beams to find a 90-degree wall-building angle for wall-building without occupying ground space or affecting staircase construction during wall-building.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing device for a laser level with a center screw hole, comprising a base and a level mounting screw, wherein the base is a magnetic fixing chassis with a mounting hole, the lower end of the level mounting screw is provided with a mounting thread for fixing the laser level, and the upper end is fixed with a magnetic fixing block, and the magnetic fixing block is adsorbed on the magnetic fixing chassis.
[0005] The level mounting screw has two sections, the upper end of the upper section is fixed with a magnetic fixing block, the lower end of the upper section is welded with a spherical shell, the spherical shell has a spherical cavity with an opening at the lower end, the upper end of the lower section of the level mounting screw is welded with a steel ball, the steel ball is located in the spherical cavity and the two form a universal rotating device.
[0006] A screw hole is opened in the lower half of the spherical cavity, and a positioning screw is arranged in the screw hole. When the positioning screw is tightened, the steel ball is fixed and positioned in the spherical cavity.
[0007] The magnetic fixing block comprises a magnet and two steel plates, and the two steel plates sandwich the magnet.
[0008] Compared with the prior art, the beneficial effects of the utility model are:
[0009] The utility model has a simple structure, and the laser level can be fixed on a roof without beams, so as to find a 90-degree wall-building angle for wall-building, while not occupying ground space and not affecting the construction of stairs when wall-building.

[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0013] from Figure 1 It can be known that the utility model provides a fixing device for a laser level with a center screw hole, comprising a base 1, a magnetic fixing block 3 and a level mounting screw, wherein the base is a magnetic fixing chassis with a mounting hole 8, the lower end of the level mounting screw is provided with a mounting thread for fixing the laser level, and a magnetic fixing block is fixed at the upper end, and the magnetic fixing block is adsorbed on the magnetic fixing chassis.
[0014] The level installation screw has two sections, the upper section is a connecting rod 4, and the lower section is a mounting screw 2. The upper end of the connecting rod is fixed with a magnetic fixing block, and the lower end is welded with a spherical shell 7. The spherical shell has a spherical cavity with an opening at the lower end. The upper end of the mounting screw is welded with a steel ball 6. The steel ball is located in the spherical cavity and the two form a universal rotation device. The lower half of the spherical cavity has a screw hole, and the screw hole has a positioning screw.
