[0035] The water supply pipe 16 is connected with a physiological saline infusion bag or bottle through a pipeline.

[0036] The fixed box 2 comprises a box body 21, and a limiting block 22 is arranged in the box body 21 and is symmetrical to the left and right, a slot 23 is formed between the limiting block 22 and the inner side of the box body 21, the tweezer tail 11 is inserted into the slot 23, and a fixed plate 24 is clamped at the opening of the front side of the box body 21 and is located between the tweezer blades 1.

[0037] The fixed plate 24 cooperates with the limiting block 22 and the box body 21 to fix the tweezer blades 1, and when the tweezer blades 1 are subjected to external force, the tweezer blades 1 will bend inward with the end of the fixed plate 24 as a fulcrum.

[0038] The fixed box 2 is made of plastic insulating material.

[0039] The transmission assembly comprises two rotating plates 31, the tail portions of the two rotating plates 31 are rotationally connected through a rotating shaft 32, and the head portions of the rotating plates 31 are rotationally connected with the two tweezer blades 1 respectively.

[0040] When the tweezer blades 1 are subjected to external force, the tweezer tips 13 are close to each other, the head portions of the rotating plates 31 are close to each other, and the tail portions of the rotating plates 31 and the rotating shaft 32 are away from the box body 21.

[0041] The rotating shaft 32 is radially penetrated by a sliding sleeve 33, a connecting rod 34 is connected with a knob 35 at the tail portion penetrating the sliding sleeve 33, and the head portion of the connecting rod 34 penetrates the fixed plate 24.

[0042] When the rotating shaft 32 is away from the box body 21, the connecting rod 34 can be driven to slide along the axis thereof through the knob 35.

[0043] The extrusion assembly comprises a connecting frame 36, the connecting frame 36 is threadedly connected with the head portion of the connecting rod 34, the connecting frame 36 is slidably connected and rotationally installed with an extrusion roller 38 at the two ends and the tweezer tail 11, and an elastic element 37 is arranged between the fixed plate 24 and the inner side of the connecting frame 36.

[0046] When the tweezer blades 1 are extruded and lose external force, the tweezer tips 13 are away from each other, and under the elastic force of the elastic element 37, the connecting frame 36 and the extrusion roller 38 are away from the fixed plate 24, so as to extrude the water supply pipe 16 again and cut off the water supply.

[0047] The rotating knob 35 can drive the connecting rod 34 to rotate, and since the connecting rod 34 is threadedly connected with the connecting frame 36, the connecting rod 34 can move along the axis thereof when the connecting rod 34 rotates.

[0048] When the connecting rod 34 moves towards the tweezer tip 13, the knob 35 is away from the sleeve 33, and the sleeve 33 needs to move a distance to contact the knob 35 in use, and then the connecting rod 34 and the connecting frame 36 are driven to move through the knob 35, so that the distance of the tweezer tip 13 is shortened when the dripping water starts.

[0049] When the connecting rod 34 has a tendency to move towards the box body 21, it is blocked by the sleeve 33, and the knob 35 and the connecting rod 34 cannot be moved, at this time the connecting frame 36 moves towards the fixed plate 24, at this time the distance of the squeezing roller 38 to the end of the pipe groove 14 is reduced, when the sleeve 33 drives the connecting rod 34 and the connecting frame 36 to move through the knob 35, only a small distance needs to be moved, and the squeezing roller 38 will release the squeezing of the water delivery pipe 16, and the trigger distance is shortened, so that the distance of the tweezer tip 13 is lengthened when the dripping water starts.

[0054] When the connecting rod 34 moves towards the tweezer tip 13, the knob 35 is away from the sleeve 33, and the sleeve 33 needs to move a distance to contact the knob 35 in use, and then the connecting rod 34 and the connecting frame 36 are driven to move through the knob 35, so that the distance of the tweezer tip 13 is shortened when the dripping water starts.

[0055] When the connecting rod 34 has a tendency to move towards the box body 21, it is blocked by the sleeve 33, and the knob 35 and the connecting rod 34 cannot be moved, at this time the connecting frame 36 moves towards the fixed plate 24, at this time the distance of the squeezing roller 38 to the end of the pipe groove 14 is reduced, when the sleeve 33 drives the connecting rod 34 and the connecting frame 36 to move through the knob 35, only a small distance needs to be moved, and the squeezing roller 38 will release the squeezing of the water delivery pipe 16, and the trigger distance is shortened, so that the distance of the tweezer tip 13 is lengthened when the dripping water starts.

[0056] The trigger distance refers to the distance between the tweezer tips 13 when starting to drip water, and the difference between the distance between the tweezer tips 13 when starting to drip water and the initial position, and the trigger distance can be adjusted in the range of 0-0.8CM, taking the tweezers with the opening of the tweezer tips 13 being 1.2cm as an example, when the trigger distance is 0.8CM, the water pipe 16 discharges water when the distance between the tweezer tips 13 is in the range of 0-0.4CM, and does not discharge water when the distance between the tweezer tips 13 is in the range of 0.4-1.2cm; when the trigger distance is 0, the water pipe 16 starts to discharge water as soon as the tweezer tips 13 start to move.
