The rotary worktable 1 rotates to drive the workpiece fixing seat 100 to rotate to the pin opening angle station of the explosion-proof sensor, namely, the explosion-proof sensor is pressed between the fixing device 702 and the pin opening mechanism 703,

first, the telescopic end of the fixed compressing cylinder 7021 extends downward, so that the fixed compressing block 7022 is compressed on the surface of the explosion-proof sensor 102 to fix the explosion-proof sensor 102, at this time, the closing-in limit baffle 710 is located in front of the stitch saddle 1071, and a distance is provided between the closing-in limit baffle 710 and the front end surface of the stitch saddle 1071, and the distance is used for the entering of the wedge 7041 and the wedge 7042.
