[0038] The utility model is provided with an L-shaped groove 401, an inner tooth ratchet 402, a sliding block 403, a return spring 404 and a limit block 405. When the annular block 202 rotates in the annular groove 201, the inclined surface of the ratchet groove of the inner tooth ratchet 402 will squeeze the inclined surface of the limit block 405, so that the sliding block 403 drives the limit block 405 to slide in the horizontal groove of the L-shaped groove 401, and the return spring 404 is forced to shrink until the end of the limit block 405 contacts the inner wall of the next ratchet groove of the inner tooth ratchet 402. At this time, the return spring 404 is no longer stressed and begins to stretch, so that the sliding block 403 drives the limit block 405 to slide in the horizontal groove of the L-shaped groove 401 in the opposite direction until the limit block 405 is engaged with the next ratchet groove of the inner tooth ratchet 402.

At this time, the arc spring 209 is no longer under force and begins to stretch, causing the adjustment block B208 and the adjustment block A206 to slide in opposite directions until the arc spring 209 returns to its original shape. At this time, the adjustment block A206 and the adjustment block B208 move to their original positions.

[0041] How it works

[0042] When using the abdominal belt which is convenient for adjusting the caliber of the stoma, firstly, according to the caliber of the patient's stoma, the annular block 202 is rotated to make the annular block 202 rotate in the annular groove 201, so that the U-shaped piece 211 slides in the opening groove 204, so that the extrusion pin 212 squeezes the extrusion groove 210, so that the adjustment block A206 slides in the adjustment groove A203, and the adjustment block B208 slides in the spring groove 207 and the adjustment groove B205, so that the arc spring 209 is forced to shrink, and when the annular block 202 rotates in the annular groove 201, the inclined surface of the ratchet groove of the inner-toothed ratchet 402 squeezes the inclined surface of the limit block 405, so that the sliding block 403 drives the limit block 405 to slide in the horizontal groove of the L-shaped groove 401, so that the return spring 404 is forced to shrink until the end of the limit block 405 is aligned with the next ratchet of the inner-toothed ratchet 402. The inner wall of the groove is in contact with the return spring 404, at which time, the return spring 404 is no longer stressed and begins to stretch, so that the sliding block 403 drives the limit block 405 to slide in the opposite direction in the horizontal groove of the L-shaped groove 401, until the limit block 405 is engaged with the next ratchet groove of the inner toothed ratchet 402. At this time, the position of the adjustment block A206 and the adjustment block B208 is fixed. If at this time, the position between the adjustment block A206 and the adjustment block B208 is not required, continue to rotate the annular block 202, the return spring 404 will continuously contract and reset, and the limit block 405 will continuously disengage from the current ratchet groove of the inner toothed ratchet 402 and engage with the next ratchet groove of the inner toothed ratchet 402, until a suitable size of caliber is formed between the adjustment block A206 and the adjustment block B208, at this time, the strap 102 can be put on the patient through Velcro;

[0043] When it is necessary to reset the adjusting block A206 and the adjusting block B208, the reset block 502 is pressed down to make the reset block 502 slide downward in the receiving groove 501, so that the transmission rod 503 moves downward, so that the inclined surface A on the wedge block A504 squeezes the inclined surface B on the wedge block B505, so that the sliding block 403 drives the limit block 405 and the wedge block B505 to slide in the horizontal groove of the L-shaped groove 401, so that the return spring 404 is forced to shrink until the limit block 405 is disengaged from the ratchet groove of the inner tooth ratchet 402. At this time, the arc spring 209 is no longer stressed and begins to stretch, so that the adjusting block B208 is in the spring groove 2 07 and the adjusting groove B205 slide in opposite directions, so that the adjusting block A206 slides in the adjusting groove A203 in the opposite direction, so that the inner wall of the extrusion groove 210 squeezes the extrusion pin 212, and the U-shaped part 211 slides in the opposite direction in the opening groove 204, so that the annular block 202 rotates in the opposite direction in the annular groove 201 until the arc spring 209 returns to its original shape. At this time, the adjusting block A206 and the adjusting block B208 move to their original positions, and then, the reset block 502 is released. Under the action of the return spring 404, the limit block 405 will be engaged with the ratchet groove of the internal toothed ratchet 402.
