[0021] The operation assembly 25 is driven to slide the push-pull rod 22, so that the piston 23 slides synchronously, which reduces the pressure in the inside of the barrel 21, so that the gas in the breast shield assembly 3 is sucked into the inside of the barrel 21, so that the gas in the breast shield assembly 3 is sucked out, so that the inside of the breast shield assembly 3 is in a negative pressure state, so that the breast shield assembly 3 is closely attached to the breast and the concave nipple is sucked out.

[0022] The operation assembly 25 includes a mounting box 251 fixedly connected to the bottom of the barrel 21, one end of the bottom of the mounting box 251 is fixedly connected with a handle 259, one side of the barrel 21 is slidably connected with a guide rod 252 penetrating through the side wall of the barrel 21, one end of the guide rod 252 is fixedly connected with a connecting plate 254, the top end of the connecting plate 254 is fixedly connected with the push-pull rod 22, the other end of the guide rod 252 is fixedly connected with a rack 253, the inside of the mounting box 251 is rotatably connected with a transmission gear 255, the transmission gear 255 is engaged with the rack 253, the bottom end of the inside of the mounting box 251 is rotatably connected with an incomplete gear 256, the incomplete gear 256 is engaged with the transmission gear 255, the bottom end of the incomplete gear 256 is fixedly connected with a push rod 257, the push rod 257 penetrates through the bottom wall of the barrel 21 and extends below the barrel 21, the outside of the barrel 21 is provided with a limiting piece 258 for limiting the one-way rotation of the incomplete gear 256.

[0023] During operation, the handle 259 is held, and then the push rod 257 is pressed by the fingers to rotate the push rod 257, which synchronously rotates the incomplete gear 256, so that the transmission gear 255 rotates, which drives the rack 253 to slide, so that the guide rod 252 drives the connecting plate 254 to move, and the push-pull rod 22 drives the piston 23 to slide, thereby reducing the pressure in the inside of the barrel 21, so that the gas in the breast shield assembly 3 is sucked into the inside of the barrel 21, so that the gas in the breast shield assembly 3 is sucked out, so that the inside of the breast shield assembly 3 is in a negative pressure state, so that the breast shield assembly 3 is closely attached to the breast and the concave nipple is sucked out, the whole process is simple to operate, the suction process can be operated by one hand, and the correction process is greatly simplified.

[0024] The limiting piece 258 includes a ratchet wheel 2581 fixedly connected coaxially with the incomplete gear 256, a pawl 2582 rotatably connected to the outside of the barrel 21, the pawl 2582 is slidably matched with the tooth groove of the ratchet wheel 2581, the pawl 2582 is fixedly connected coaxially with a rotating cap 2583 on one side, a torsional spring 2584 is sleeved on the pin shaft of the pawl 2582, one end of the torsional spring 2584 is welded with the rotating cap 2583, and the other end of the torsional spring 2584 is welded with the outer wall of the barrel 21.

[0025] By holding the handle 259, and then pressing the push rod 257 with fingers, the push rod 257 is rotated, which makes the incomplete gear 256 rotate synchronously, the ratchet wheel 2581 rotates synchronously, and the pawl 2582 can limit the ratchet wheel 2581 from reverse rotation, so that the handle 259 is released, the push rod 257 still maintains the current position, and thus the hand pressure can be relaxed;

[0026] When it is needed to separate the breast shield assembly 3 from the breast, the pawl 2582 is rotated and separated from the ratchet wheel 2581 by rotating the rotating cap 2583, at this time, the reset spring 24 releases potential energy, the piston 23 reversely slides, the gas in the cylinder body 21 is introduced into the breast shield assembly 3, which makes the pressure in the breast shield assembly 3 increase, so that the breast shield assembly 3 is separated from the breast.

[0027] The breast shield assembly 3 comprises a shield body 31, one end of the shield body 31 is fixedly connected with an internally threaded sleeve 32, the pipe opening of the gas guide pipe 1 is fixedly connected with an externally threaded pipe 33, and the externally threaded pipe 33 is in threaded cooperation with the internally threaded sleeve 32.
