Rapidly-detached hoop of line type sensor

The invention belongs to the aviation field, and relates to a rapidly-detached hoop of a line type sensor. The rapidly-detached hoop of the line type sensor comprises an upper pressing piece (2), a lower pressing piece (6), a base (3), a rotary shaft (5) and a locking device. The line type sensor is embedded in an insulating bush and then put in a clamping groove formed among the upper pressing piece (2), the lower pressing piece (6) and the base (3), and then the upper pressing piece (2) is pressed by pressing an installation pin (1). When the installation pin (1) penetrates through the clamping groove of the base, the installation pin (1) is rotated, and then locking of the rapidly-detached hoop is completed. The rapidly-detached hoop is suitable for installation of the line type sensor on an engine structure, and is simple in structure and capable of achieving rapid mounting and dismounting of the line type sensor; and meanwhile the problem that time and labor are wasted when the line type sensor is installed through common standard parts is solved.
