Heat insulation double-layer magnetic shielding structure of high-precision fiber-optic gyroscope fiber-optic sensitive ring assembly

The utility model discloses a heat-insulating double-layer magnetic shielding structure of a high-precision fiber-optic gyroscope fiber-sensitive ring component, which comprises a device main body and a dismounting mechanism arranged in the device main body. By arranging a fixing block, when a fiber-optic gyroscope is used in daily life, in order to facilitate the replacement convenience of a chip main body after long-time use, the chip main body can be conveniently detached from the device main body; when the chip needs to be installed, a rotary knob can be rotated to drive a threaded sliding block to slide along the inner wall of a fixing groove through the rotation of a threaded rod, the sliding of the threaded sliding block drives a fixing block to slide along the outer wall of a placing box through the connection of a connecting wedge block, and meanwhile, the chip is fixedly arranged in the fiber-optic gyroscope; the chip main body is placed in the positioning groove, and the fixing block is driven to c
