Further, the dismounting part 201 comprises an inner hexagonal sleeve 203 and a sleeve interface 204, and the inner hexagonal sleeve 203 is matched with the buzzer sensor nut. The sleeve member 202 includes a circular boss 205 and a flashlight 206 disposed in the middle of the long tube 103, the circular boss 205 being disposed on one side of the hexagonal socket 203. The inner hexagonal sleeve 203, the circular boss 205 and one side of the T-shaped handle 104 are all provided with an edge groove 106. In specific design data, in the process of assembling and disassembling the CP216 type buzzer sensor, one end of the sensor is a socket 203 (with a depth of 50mm) of a hexagon socket M16 type, a circular boss 205 (with an external thread M20 × 1.5 on the boss surface) with an external diameter of 25mm is arranged at the position of the left end opening of the socket interface 204 and the socket 203 tool and towards the right 80mm, and the circular boss is in threaded connection with the protection ring (with a wall thickness of 3mm) through a protection ring (with an internal thread M20 × 1.5). The whole surface of the long tube 103 of the device body 100 is provided with side grooves 106 (with a distance of 5mm) communicating with the inner cavity, and the protection ring is also provided with grooves of the same size. The internal and external threads arranged inside the circular boss 205 can protect the long pipe 103 structure by the circular boss 205. Because the hexagonal socket 203 is subjected to a large torque when the sensor nut is rotated in a matching manner, and on the other hand, the entire device body 100 is provided with the side groove 106 for accommodating the lead wire, the stability of the structure is not sufficient, so that the circular boss 205 can prolong the service life of the long tube 103 and avoid the twisting-off condition. Meanwhile, because the circular boss 205 is in threaded connection with the protection ring 207, the design of the internal and external threads of the protection ring 207 and the circular boss 205 can be matched with the side groove 106 and the hook 107 for use.

The flashlight power distribution facility needs to adopt weak current batteries because the batteries can influence the normal work of the buzzer inductor due to the strong working environment. The bottom of the inner hexagonal sleeve 203 is provided with a sleeve interface 204, and the sleeve interface 204 is connected with one end of the long tube 103 in a matching way. The provision of the sleeve interface 204 may allow for different sensor nuts to be replaced through the sleeve interface 204 when the sensor nut is no longer hex-shaped. The connection mode can be welding or threaded connection.

The operation process is as follows: a cable (about 500 mm) led out from the end part of the sensor is straightened by hand, the peripheral part 101 is vertically placed, the protection ring 207 is rotated until the direction of the opening side groove 106 is consistent with that of the long pipe side groove 106, then the straightened cable is placed into the cavity, the protection ring 207 is rotated to enable the opening side groove 106 to rotate to other positions (the torque can be enhanced, the tool is prevented from being deformed when being used), then the inner hexagonal sleeve 203 is meshed with an outer hexagonal nut at the end part of the sensor, and finally the sensor can be detached by rotating the T-shaped handle 104; the mounting sensor operates similarly.

Finally, the buzzing sensor on the outer surface of the V94.3 type gas turbine body can be safely and quickly detached or installed, the sensor cannot be damaged, and the artificial loss is reduced to the maximum extent.

The rest of the structure is the same as in example 1.
