Meanwhile, the gear 5 is meshed with the circular tooth rod 9, so that the gear 5 can drive the circular tooth rod 9 to move upwards along the axial direction under the guidance of the guide sleeve 1 when rotating anticlockwise, the circular tooth rod 9 drives the clamping shell 10 to move upwards synchronously, the clamping shell 10 clamps the medicament tube 12 through the clamping flap 19 to drive the medicament tube 12 to move upwards, and the medicament tube 12 rotates towards the respective outer side simultaneously under the combined action of rolling friction force and restoring force of the torsion spring 27 in the process of moving upwards relative to the rolling rollers 11 on the two sides, namely the eccentric position of the rolling rollers 11, and the gap between the two rolling rollers 11 is gradually reduced when rotating, so that the effect of rolling and squeezing medicament more tightly is achieved on the medicament tube 12, and the medicament in the medicament tube 12 is squeezed out from the lower end hose and is sprayed out from the medicament feeding head 16.

When the pressing rod 6 is pressed to the bottom and then the circular gear rod 9 is required to continuously lift, the pressing rod 6 is reversely lifted upwards, in the lifting process, the gear 5 can be driven to rotate only by the gear 5 meshed with the circular gear rod 9 needing large pulling force, the inner side face of the clamping tooth 14 of the one-way clamping tooth block 7 is subjected to the lateral force of the gear 5, the rear end of the one-way clamping tooth block 7 is connected with the inside of the abdicating groove 13 through the reset spring 8, the gear 5 meets the requirement that the pulling force capable of rotating is larger than the elastic restoring force of the reset spring 8, and therefore the gear 5 cannot rotate in the lifting process of the pressing rod 6. The back of one-way screens tooth piece 7 props section 15 and pushes down reset spring 8 and makes the screens tooth 14 of one-way screens lug front end can lift the tooth alveolus that breaks away from gear 5, reset spring 8 is in compression state this moment, reset spring 8 props section 15 to the top and has elastic restoring force, make one-way screens tooth piece 7 can make one-way screens tooth piece 7 mesh under the effect of elastic restoring force in the tooth alveolus at reverse reset spring 8 through each tooth alveolus of gear 5, thereby can let depression bar 6 push down depression bar 6 and rotate through one-way screens tooth piece 7 control gear 5 when lifting up the tooth alveolus of gear 5 that arbitrary angle corresponds, thereby realized that round rack bar 9 axial rises the mesh of continuously extruding the inside medicament of medicament pipe 12.

The utility model discloses an innovation technical point and beneficial effect lie in at least:

1. this device has realized carrying out the rotary type through depression bar 6 circulation and has lifted up and can control the effect that the ratch 9 continuation rises along the axial with pushing down, and the one-way screens tooth piece 7 cooperation of inside lets a groove 13 and reset spring 8 play the purpose of single rotation to driven to gear 5. Reset spring 8 can make one-way screens tooth piece 7 all mesh in inside in each tooth alveolus of reverse process gear 5 to can let depression bar 6 lift up arbitrary angle and all can push down drive gear 5, lift up the angle to the difference that different operating personnel used to separately and have the commonality, and one-way continuation infusion medicament can avoid the medicament two-way flow to appear and lead to the condition of backward flow, very big improvement efficiency.

2. The pressing rod 6 is held and pressed by the whole palm of an operator, the labor-saving lever is adopted on the whole structure to hold and press the pushing circular toothed rod 9, and compared with an injector type medicine feeding device, the manual force of the operator is greatly saved, and the exhaustion condition can not occur.

3. The tapered clamping shell 10 is internally embedded with the clamping petals 19 which can slide left and right through a dovetail groove 18 structure, and the distance between the clamping surfaces 21 of the two clamping petals 19 can be reduced through downward jacking of the jacking springs 23, so that the clamping surfaces are clamped more and more tightly. Meanwhile, the top bracing spring 23 is adopted, so that the medicine tube clamp has universality and can clamp medicine tubes 12 with different thicknesses.

4. Two sets of roller 11 that roll of symmetry all adopt eccentric hinge can make two interval between the roller 11 that rolls adjustable, have the commonality to the medicament pipe 12 of equidimension not. The cooperation torsional spring 27 provides rotation restoring elasticity to the roller 11 for both sides roller 11 can press from both sides tightly the medicament pipe 12 simultaneously, makes the medicament pipe 12 atress can be more even. Meanwhile, the medicament tube 12 is pulled upwards relative to the rolling roller 11, so that the rolling roller 11 has the tendency of inwards rotating on the outer wall of the medicament tube 12 due to rolling friction, the medicament tube 12 can be clamped more and more tightly, the condition that the medicament is remained and is not extruded cannot occur, and the medicament waste cannot be caused.
