The bracket 2 is composed of an upper hemisphere 21, a lower hemisphere 22 and a middle pillar 23 located between the upper and lower hemispheres. The large planes of the upper and lower hemispheres are opposite to each other. The heads of the upper and lower hemispheres are cut off to form small planes parallel to the large planes. The spectrum monitor body 1 can be detachably mounted on the small plane of the upper hemisphere 21, and the middle pillar 23 can be retracted in the height direction.

[0026] In the present invention, the middle support 23 can be extended and retracted in the height direction to adjust the height of the bracket 2, and then adjust the height of the spectrum monitor body 1, effectively meeting the needs of different monitoring positions. The bracket 2 is composed of an upper hemisphere 21 and a lower hemisphere 22, and the surface is a smooth curved surface to avoid damage to objects or human body when the device is placed, stored, and used, and is easy to transfer.

[0027] As an optional embodiment, Figure 2As shown, the middle support 23 is formed by stacking multiple groups of hollow pipes 231. A pin hole is opened on the wall of the pipe 231, and a plug 232 is inserted into the pin hole. One end of the plug 232 is connected to an elastic element, and the other end extends out of the pipe and the extension length is greater than the gap between the lower pipe and the upper pipe. The elastic element is fixed in the pipe. By pressing the plug 232, the elastic element is compressed, the upper pipe falls into the lower pipe, and a cavity is set in the lower hemisphere. The lowermost pipe falls into the cavity of the lower hemisphere, realizing compression in the height direction; pulling upward, the plug is reset under the stretching action of the elastic element, realizing stretching in the height direction.

[0028] Specifically, the pipe 231 is made of metal or alloy to ensure the support strength. The pipe 231 has a certain thickness and a large diameter, so that the entire device is placed more stably and is not easy to tilt or move. The elastic element is an elastic and retractable component, such as a spring.

[0029] As an optional embodiment, Figure 2 As shown, a columnar rib 233 is axially provided on the outer wall of the pipe 231 to prevent the pipe from falling rapidly when the latch 232 is pressed.
