The rotating frame 9 passes through the fixed base 1, and the outer side of the rotating frame 9 is slidingly connected to the inner side of the fixed base 1, and the front and rear ends of the rotating shaft 8 are rotationally connected to the inner side of the fixed base 1. By setting a rotatable rotating frame 9, small precision instruments on the upper end of the placement table 2 are clamped and limited, so that precision instruments of different sizes can be stably placed on the placement table 2, thereby improving the adaptability of the fixed base 1 and the precision instruments.

[0023] The left and right sides of the lower end of the placing table 2 are fixedly connected with support rods 11, and the outer side of the support rod 11 is slidably connected to the inner side of the fixed base 1. A limiting rod 12 is arranged at the lower end of the support rod 11, and the lower end of the limiting rod 12 is fixedly connected to the inner side of the fixed base 1. A supporting spring 13 is wrapped around the outer side of the limiting rod 12, and the upper end of the supporting spring 13 is fixedly connected to the lower end of the support rod 11, and the lower end of the supporting spring 13 is fixedly connected to the inner side of the fixed base 1. The support rod 11 at the upper end is supported by the spring 13 at the upper end of the limiting rod 12, thereby increasing the space for adjusting the inclination of the placing table 2 in the fixed base 1.

[0024] The left and right ends of the upper end of the placing table 2 are slidably connected with push rods 14, and the push rods 14 penetrate the placing table 2, the lower end of the push rods 14 is fixedly connected with a rotating block 15, and the front and rear ends of the rotating block 15 are rotatably connected to the inner side of the placing table 2, the lower end of the rotating block 15 is fixedly connected with a connecting rod 16, and the connecting rods 16 penetrate the placing table 2 and the fixed base 1, the outer sides of the connecting rods 16 are slidably connected to the inner sides of the placing table 2 and the inner sides of the fixed base 1, the lower end of the connecting rod 16 is fixedly connected with a connecting block 17, and the outer side of the connecting block 17 is slidably connected to the fixed base 1, and the connecting block 17 is located on the inner side of the fixed base 1, and the connecting block 17 at the lower end can be moved left and right in the fixed base 1 by pushing the push rods 14 left and right.

[0026] Working process: When the utility model is used, the fixed base 1 is placed on the work surface where the test is required. If the work surface is tilted, it can be reflected by the liquid level on the upper end of the placement table 2. At this time, the push rod 14 at a higher position can be manually pushed, such as pushing the push rod 14 at the left end to the right. The push rod 14 takes the rotating block 15 as the center of the circle so that the connecting rod 16 at the lower end moves to the left with the connecting block 17 in the fixed base 1. At this time, the deformation rod 18 is deformed to the front and rear sides under the action of the support rod 11 until it is out of contact with the support rod 11. At this time, the support rod 11 has no limit, and the placement table 2 can be pushed up manually or according to the elasticity of the support spring 13. Through the liquid level Check whether the placement table 2 is in a horizontal state. If it is in a horizontal state, reset the push rod 14 and then place the small precision instrument at the upper center of the placement table 2. At this time, connect the power supply and start the micro motor 3 inside. The micro motor 3 drives the first bevel gear 4 to rotate, and then engages with the second bevel gears 5 at the left and right ends, so that it rotates with the threaded rod 6 at the same time. When the sliding rod 7 outside the threaded rod 6 slides to both ends at the same time, the sliding rod 7 makes the rotating shaft 8 rotate with the rotating frame 9 at the same time, and the rotating frame 9 rotates toward the position of the precision instrument with the rotating shaft 8 as the center until the damping block 10 in the rotating frame 9 contacts it, thereby facilitating the fixing of the precision instrument on the placement table 2.
