When the force of twisting the housing 5 increases and exceeds the force of the pressure spring 54, the teeth of the ratchet 4 abut against the jack 53 and move the end of the jack 53, the pressure spring 54 is compressed, and a slip phenomenon occurs between the jack 53 and the ratchet 4. At this time, even if a larger force is applied to the housing 5, the ratchet wheel 4 does not continue to rotate and remains at the set torque value. According to the adjusting tightness requirement of the chain, the adjusting rod 3 with a proper torsion value is selected, when the maximum torsion value is reached, the adjusting rod 3 does not rotate continuously, the ratchet wheel 4 can apply excessive acting force to the outside to release force, and whether the current adjusting tightness degree of the chain reaches the standard can be judged better.

When the gap between the ratchet 4 and the cover plate 52 is reduced by the adjustment bolt 521, one end of the carrier rod 53 abutting the teeth of the ratchet 4 gradually moves toward the inside of the housing 51, thereby gradually compressing the pressure spring 54, and the elastic force of the pressure spring 54 increases. Similarly, when the gap between the ratchet 4 and the cover plate 52 is increased by adjusting the bolt 521, one end of the carrier 53 abutting against the teeth of the ratchet 4 gradually moves toward the axis of the ratchet 4, and the compressed pressure spring 54 is gradually released, and the elastic force of the pressure spring 54 is reduced. By changing the position of the ratchet wheel 4, the torque value required for slip between the housing 51 and the ratchet wheel 4 is changed.
Further, the adjusting bolt 521 can drive the ratchet 4 to move toward the cover plate 52 or away from the cover plate 52, that is, the adjusting bolt 521 drives the bottom wall of the housing 51 to slide back and forth on the adjusting lever 3. Accordingly, a scale (not shown) is provided on a section of the adjustment lever 3 between the ratchet 4 and the fixed block 2, and a current scale is covered by the bottom wall of the housing 51 to display a torsion value corresponding to the current pressure spring 54. The torsion value of the whole chain regulator is visualized, and the use is more convenient.
