Third, the left end of the second stop motion bar (33) of the adjustable stop motion assembly (3) is inserted into the groove (27), the second stop motion bar (33) and the connecting seat (36) are inserted into the stop motion slot (35) of the left stop motion box (31), the connecting seat (36) drives the first stop motion bar (32) to be inserted into the second stop motion bar (33), the yarn is threaded through the stop motion sensing needle (4), the stop motion sensing needle (4) is located on the first stop motion bar (32) and the second stop motion bar (33), when stopping, the stop motion sensing needle (4) falls downward to the first stop motion bar (32) or the second stop motion bar (33), the stop motion sensing needle (4), the first stop motion bar (32) and the second stop motion bar (33) cooperate to determine the stop, the stop motion box (31) controls the stop in time, when the stop motion sensing needle (4) falls downward, the first through hole (38) or the sliding groove (37) is blocked by the stop motion sensing needle (4), the ultrasonic waves of the ultrasonic probe (34) are reflected to the ultrasonic probe (34) through the stop motion sensing needle (4), the time is calculated, the specific position of the stop motion sensing needle (4) on the adjustable stop motion assembly (3) is determined, the specific position of the falling stop motion sensing needle (4) can be quickly positioned, and the position of the stopped yarn is accurately found.
