And an arc-shaped lower pressing wall 6211 is formed at the lower part of the side wall of the lower pressing plate far away from the center of the upper cylinder.

When the one-way pawl is in a clamping state, the arc pressing wall abuts against the inclined positioning wall of the one-way pawl, the pawl body abuts against the ratchet rod, in the process of longitudinal movement of the longitudinal moving frame, the arc pressing wall drives the pawl body on the one-way pawl to always abut against the ratchet rod, and the one-way pawl is kept in the clamping state.

The lower end surface of the lower pressing plate is a lower pressing positioning wall 6212 which is horizontally arranged.

When the one-way pawl is in a vertical state, the downward pressing positioning wall is abutted against the horizontal positioning wall, the pawl body is separated from the ratchet rod, in the process of longitudinal movement of the longitudinal moving frame, the downward pressing positioning wall is always abutted against the horizontal positioning wall, and the one-way pawl is kept in a vertical state.

And a lower pressing spring 622 for driving the lower pressing plate to abut against the one-way claw is fixedly connected between the upper end of the lower pressing plate and the longitudinal moving frame.

The driving protrusions are uniformly formed at the upper end of the side wall of the ratchet rod and are positioned at the lower end of the piston body.

Referring to fig. 12 and 13, the one-way claw in fig. 12 is in a vertical state, and at this time, the pressing portion is repeatedly pressed, so that the pressing portion draws away air in a closed space formed by the upper cylinder, the pressure in the closed space is reduced, a negative pressure environment is formed, the pressure at the upper end of the piston body is greater than the pressure at the lower end of the piston body, and the piston body drives the steel needle to move downwards towards the upper cylinder; meanwhile, the pressing part drives the longitudinal moving frame to move up and down, and the one-way pawl is in a vertical state and does not contact with the ratchet rod, so that the reset mechanism does not work.

The piston body gradually moves downwards along with the gradual reduction of the air pressure in the upper cylinder body, when the piston body moves to be close to the bottom in the sliding groove of the piston body, the lower end of the driving bulge is positioned below the sliding groove of the piston body, the pressing part is continuously pressed downwards at the moment, the longitudinal moving frame also moves upwards in the process that the pressing part moves upwards under the action of the reset spring, at a certain moment, the lower end of the driving bulge is abutted against a lower pressing rod of a driving part on the one-way pawl driving part to prevent the one-way pawl driving part from moving upwards, the longitudinal moving frame continues moving upwards to further enable the one-way pawl driving part to move downwards relative to the longitudinal moving frame, the one-way pawl driving rod generates thrust on a rotating wall of the one-way pawl, the lower part of the one-way pawl rotates towards the direction of the ratchet rod, the one-way pawl is changed into a, the arc pressing wall is abutted against the inclined positioning wall of the one-way claw, so that the one-way claw is kept in a clamping state, the piston body is located at the limit position below, and the needle body is pushed into the body of a patient.

When the lower end of the driving protrusion abuts against the upper end of the one-way claw driving part and the one-way claw is changed from a vertical state to a clamping state, due to the fact that the upper cylinder body is in a negative pressure environment, the negative pressure generates a resultant force F1 of a downward pulling force on the piston body and a friction force between the piston body and the sliding groove of the piston body, when the longitudinal moving frame moves upwards, the one-way claw generates an upward component force F2 on the one-way claw driving part, and F1 is larger than F2, and therefore the piston body cannot move upwards together with the longitudinal moving frame.

Referring to fig. 13 and 14, the piston body in fig. 13 is at the lower limit position, the lower cylinder is separated from the patient, the upper cylinder is communicated with the outside and cannot form a closed space, then the pressing portion is pressed down, when the pressing portion drives the longitudinal moving frame to move downwards, the one-way pawl slides relative to the ratchet rod, when the pressing portion drives the longitudinal moving frame to move upwards, the pawl body of the one-way pawl drives the ratchet rod to move upwards, the above process is repeated, and the piston body gradually moves upwards.

In the process, the pawl body of the one-way pawl moves along the surface of the ratchet rod, so that the one-way pawl rotates, and the arc pressing wall on the pressing plate is always contacted with the rotating wall of the one-way pawl in the process.

As shown in fig. 7, the guide table is tapered, and the maximum length of the guide table is greater than the length of one ratchet tooth.

As shown in fig. 14, when the piston body moves to the position where the guide table and the pawl body of the one-way pawl approach or contact each other, the pressing portion is pressed downward, the longitudinal moving frame drives the one-way pawl to move downward, the pawl body of the one-way pawl moves along the surface of the guide table, the upper portion of the one-way pawl rotates in the direction of approaching the ratchet rod, when the pawl body of the one-way pawl contacts the lower end of the outer wall of the guide table, the inclined positioning wall 645 of the one-way pawl is separated from the circular arc pressing wall 6211, the horizontal positioning wall 641 of the one-way pawl contacts the pressing wall 6212, and the included angle between the horizontal positioning wall 641 and the pressing wall is smaller than 10 °, so that the horizontal positioning wall 641 of the one-way pawl and the pressing wall 6212 are parallel and abut against each other under the action of the pressing spring, the one-way pawl continues to rotate by an angle, the pawl body of the one-way pawl separates from the guide table, the one-way pawl is in the, the piston body is now in the upper extreme position (as shown in fig. 12).

In the process that the one-way claw is changed from the clamping state to the vertical state under the action of the guide table, the downward component force generated by the one-way claw on the guide table is smaller than the friction force between the piston body and the piston body sliding groove, and therefore the piston body cannot slide downwards in the process.

The lower cylinder body is made of transparent materials, so that the state of the steel needle can be observed conveniently.
