It should be understood that the implementation methods described herein are only used to explain this application and are not used to limit this application.

[0022] The utility model provides the following Figure 1-6 The metallographic microscope fixed support shown in the figure comprises a fixed base 1, a microscope body 2 is rotatably connected to the fixed base 1, a fixing groove 3 is provided on the bottom wall of the microscope body 2, and a limiting component 4 is provided in the fixing groove 3, the limiting component 4 comprises a fixing block 4.1 which is arranged in the fixing groove 3 and fixedly connected to the bottom wall of the microscope body 2, a connecting rod 4.2 is penetrated through the fixing block 4.1, a pulling block 4.3 is fixedly connected to the top end of the connecting rod 4.2, a connecting block 4.4 is fixedly connected to the bottom end of the connecting rod 4.2, and a sleeve is formed between the connecting block 4.4 and the fixing block 4.1 The spring 4.5 arranged on the outside of the connecting rod 4.2 is connected, the bottom of the connecting block 4.4 is fixedly connected to the limiting block 4.6, and a plurality of limiting grooves 4.7 cooperating with the limiting block 4.6 are arranged on the fixed base 1. Two fixing components 5 are arranged at the bottom of one end of the fixed base 1. The two fixing components 5 both include a right-angle plate 5.1 arranged at the bottom of the fixed base 1 and fixedly connected to the fixed base 1. A screw 5.2 is threadedly connected to the bottom wall of the right-angle plate 5.1. A rotating rod 5.3 is fixedly connected to the bottom end of the screw 5.2, and a clamping block 5.4 is rotatably connected to the top of the screw 5.2.

[0023] like Figure 3 As shown, in the present invention, the microscope body 2 and the fixed base 1 are rotatably connected via a rotating shaft 6, thereby improving the stability of the microscope body 2 when rotating.

[0024] like Figure 1 , Figure 3 , Figure 5As shown, in the utility model, a guide hole is provided on the fixed block 4.1 for the connecting rod 4.2 to pass through. When the pull block 4.3 is pulled, the connecting rod 4.2 is driven to move upward, and the stability of the movement of the connecting rod 4.2 is improved through the guide hole; the number of the limiting grooves 4.7 is four and they are distributed in a ring array about the rotating shaft 6.

[0025] like Figure 4 As shown, in the utility model, the screw 5.2 passes through the bottom wall of the right angle plate 5.1 and a thread groove is provided on the bottom wall of the right angle plate 5.1 for the screw 5.2 to pass through; the top end of the screw 5.2 is rotatably connected to the clamping block 5.4 through a bearing 5.5.

[0026] Working principle: When the utility model is implemented, the device is first installed on the desktop 7. At this time, the rotating rod 5.3 is rotated to drive the screw 5.2 to rotate. Since the screw 5.2 is threadedly connected to the bottom wall of the right-angle plate 5.1, and the screw 5.2 is rotatably connected to the clamping block 5.4 through the bearing 5.5, when the screw 5.2 rotates, it will slide upward, thereby driving the clamping block 5.4 to move upward to clamp and fix the desktop, which can stably fix the microscope body 2, avoid the displacement of the microscope body 2, and improve the stability of the microscope body 2; then pull the pull block 4.3 upward, The limit block 4.6 is driven to move upward by the connecting rod 4.2 and the connecting block 4.4, so that the limit block 4.6 is disengaged from the limit groove 4.7. At this time, the spring 4.5 is in a compressed state, and then the microscope body 2 can be rotated to rotate on the fixed base 1 through the rotating shaft 6, and the microscope body 2 is rotated to an angle facing the staff. Then the pulling block 4.3 is released, and the elastic potential energy of the spring 4.5 restores it to its original state, so that the limit block 4.6 moves downward into the limit groove 4.7, thereby realizing the installation and fixation of the microscope body 2, and the microscope body 2 can be installed at various angles.

[0027] The above implementation modes are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned implementation modes, a person skilled in the art should understand that the technical solutions described in the aforementioned implementation modes can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the implementation modes of the present invention.
