DETAILED DESCRIPTION

[0019] 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.

[0020] As attached Figure 1 -Attached Figure 5 As shown, a two-degree-of-freedom bearing platform includes a base plate 1, a sleeve 2 is connected to the middle position of the upper part of the base plate 1, and the sleeve 2 is fixedly installed on the base plate 1 by bolts. The sleeve 2 is arranged vertically, and a bearing seat 3 is rotatably arranged on the upper part of the sleeve 2. A clearance fit is adopted between the sleeve 2 and the bearing seat 3, and a bearing is installed between the sleeve 2 and the bearing seat 3, so that the bearing seat 3 can rotate smoothly on the sleeve 2. A base 4 is fixedly installed on the upper end of the bearing seat 3 by screws, and a lifting mechanism 5 is installed on the base 4. The lifting mechanism 5 is drivingly connected with a clamping block 6, and the driving end of the lifting mechanism 5 is arranged upward. The clamping block 6 is rotatably arranged on the driving end of the lifting mechanism 5. A support column 7 is connected to the base 4, and a placement platform 9 is hinged on the upper part of the support column 7. The upper end of the clamping block 6 is slidably connected to the placement platform 9. A plurality of mounting blocks 12 are arranged on the upper part of the placement platform 9, and two mounting blocks 12 are arranged, and the two mounting blocks 12 are arranged opposite to each other. The material instrument and the like are placed between two mounting blocks 12 on the placement platform 9, and bolts are screwed into the mounting blocks 12 to clamp the material instrument and fix it.

[0021] The bearing seat 3 can rotate on the sleeve 2, thereby driving the placement platform 9 to rotate through the base 4 and the support column 7; the lifting and lowering of the clamping block 6 is controlled by the lifting mechanism 5, and the placement platform 9 can be lifted or pulled down, thereby realizing the change of the angle of the placement platform 9, thereby realizing the position adjustment of the material instrument.

[0022] The upper part of the support column 7 is connected to a mounting platform 8, a hinge 10 is installed on the mounting platform 8, the lower end of the placement platform 9 is connected to the hinge 10, and the placement platform 9 is hinged to the mounting platform 8 through the hinge 10. At least two hinges 10 are provided to ensure the stability of the hinge between the placement platform 9 and the mounting platform 8.

[0023] like Figure 3 As shown, a sliding groove 13 is provided on the placement platform 9, and the sliding groove 13 is arranged along the length direction of the placement platform 9. A wheel shaft 14 is installed on the upper part of the clamping block 6, and the wheel shaft 14 passes through the sliding groove 13, and the wheel shaft 14 is perpendicular to the sliding groove 13. A rotating wheel 15 is rotatably arranged on the wheel shaft 14, and the rotating wheel 15 is located in the sliding groove 13. When the clamping block 6 moves up and down, the rotating wheel 15 can move along the sliding groove 13, and the placement platform 9 is lifted or pulled down by the cooperation of the rotating wheel 15 and the sliding groove 13.
