The detection head is used for detecting threads. The motor 1 is a servo motor 1.

[0027] The electric thread detection device of this embodiment, through the cooperation of the motor 1, the regulator 2 and the coupling 3, converts the rotation of the motor 1 into the telescopic movement of the quick-release assembly 4 and the detection head, and can automatically adjust the linear movement of the detection head, thereby realizing automatic detection of the thread, improving the detection efficiency and reducing errors.

[0028] like Figure 4 As shown in Figure 5, the quick-release assembly 4 includes a telescopic sleeve 41, a limit sleeve 42, a connecting sleeve 43, a disc spring 44, a fixed block 45 and a clamping claw 46.

[0029] By using the quick-install assembly 4, the clamping jaws 46 can be loosened and clamped only by pushing the finger sleeve 47 and the telescopic sleeve 41, thereby realizing the rapid replacement of the detection head.

[0030] The regulator 2 includes a main shaft 31, a telescopic column 32, a sleeve 33 and a fastening bolt 34.
