The specific embodiment

Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.

Fig. 1 is the structural representation of a kind of embodiment of the present utility model; Fig. 2 is an embodiment shown in Figure 1 vertical view of the present utility model.By Fig. 1 in conjunction with Fig. 2 as can be known: this veterinary syringe mainly is made of syringe 5, syringe needle 1, handle 7 etc.Wherein syringe 5 is fixed on the top of handle 7, has a rubber piston 51 in the syringe 5, and rubber piston 51 is connected with piston push rod 52, and the afterbody of piston push rod 52 is provided with piston push pedal 13.Syringe 5 has and triggers lever 6, and the power arm 61 that triggers lever 6 is gradually to syringe needle 1 direction bending, and its front end extends near the syringe needle 1, triggers lever 6 front ends and has a fork-shaped portion or bar hole 2, and syringe needle 1 passes in fork-shaped portion or bar hole 2.

The fulcrum 62 that triggers lever 6 is arranged on the handle 7, and a bit being connected with an end of spring 9 on the resistance arm 63 of triggering lever 6, the other end of spring 9 is arranged on the handle 7.In addition, also can be as Fig. 4 or shown in Figure 5, spring 9 not, sheathed torque spring 18 on the hinge at fulcrum 62 places of the resistance arm 63 that triggers lever 6 also can be realized above-mentioned functions.

The resistance arm 63 that triggers lever 6 is provided with screw thread 15, and by Fig. 3 further as can be known, discoideus lock 13 also is provided with the female thread 131 that cooperates with screw thread 15, so lock 13 can be screwed on the resistance arm 63 that triggers lever 6.The top of lock 13 is higher than the bottom of piston push pedal 14, therefore piston push rod 52 can be blocked, for after pulling spanner lever 4, piston push pedal 14 can be squeezed the end face of driving lock 13 and the bolt 13 that is insured blocks, can utilize inclined plane principle, be provided with inclined-plane or cambered surface in lock 13 inner faces (end faces of armrest handle 7 one sides) edge, or be provided with inclined-plane or cambered surface in the outer face of piston push pedal 14, certainly preferably in the inner face edge of lock 13 and the outer face of piston push pedal 14 inclined-plane or cambered surface are set all, piston push pedal 14 just can be squeezed the end face of driving lock 13 smoothly like this.In addition, in order to realize calibrated shot, resistance arm 63 surfaces of triggering lever 6 preferably indicate scale 17, therefore rotate lock 13, just it can be moved to the position that injection needs dosage.In order to allow lock 13 that piston push rod 52 is blocked, also can directly adopt another embodiment (as shown in Figure 4), promptly the afterbody at piston push rod 52 is provided with bayonet socket 53, directly with the top holding of lock 14 in bayonet socket 14.

Fig. 5 is the structural representation of another embodiment of the present utility model; As shown in Figure 5, its piston push rod 52 is provided with screw thread 54, and piston push pedal 13 centers are provided with the through hole that cooperates with piston push rod 52.Extension spring 11 is nested with on piston push rod 52, and the front end of extension spring 11 is connected with syringe bonnet 10, and the end of extension spring 11 is connected with extension spring nut 22 on being screwed on piston push rod 52, also is provided with a clamp nut 23 on piston push rod 52.Rotate clamp nut 23, just piston push pedal 52 can be pressed and put on extension spring nut 22.

Certainly, neither unique technical side's means on the connected mode of the installation site of the connected mode of piston push pedal 52 and extension spring 11, extension spring 11, piston push pedal 13 and piston push rod 52.As shown in Figure 4, the center of piston push pedal 13 is provided with screwed hole, so this piston push pedal 13 can directly be screwed on piston push rod 52.As shown in Figure 6, the afterbody of piston push rod 52 is provided with screw thread 55, and clamp nut 23 is screwed on piston push rod 52 afterbodys.The center of piston push pedal 13 is provided with push pedal through hole 26, syringe bonnet 10 centers are provided with bonnet screwed hole 101, the front end of extension spring 11 is connected with preceding perforated screw 19, should preceding perforated screw 19 be screwed in the bonnet screwed hole 101, the end of extension spring 11 is connected with back perforated screw 25, after the front end of back perforated screw 25 passes push pedal through hole 26, be screwed in the internal thread hole 27 of clamp nut 23.By the screwing togather of back perforated screw 25 and clamp nut 23, just piston push pedal 13 firmly can be fixed on the piston push rod 52 like this.

In addition, extension spring 11 can also be provided with separately except being nested with on the piston push rod 52, as long as an end of extension spring 11 is connected with piston push pedal 13, the other end is fixed on the object that handle 7 or other and syringe 5 be connected also can realize above function.

Referring to Fig. 1,2,4,5, two inhale medicine push rods 8 syringe 5 both sides that are placed in, and the shaft of inhaling medicine push rod 8 passes handle 7 vertical spacing holes 71, and the free end of its front end and spanner lever 4 is hinged, and its end withstands in the piston push pedal 13 or with piston push pedal 13 fixedlys connected.Therefore, hands is pinched spanner lever 4, just piston push pedal 13 can be backed down backward.Fig. 5 also provides a kind of better embodiment in addition, promptly one push rod push pedal 24 is set again at the end of inhaling medicine push rod 8, this push rod push pedal 24 and piston push pedal 13 contact (on-fixed is connected), are with on the hinge at fulcrum 3 places of spanner lever 4 to allow spanner lever 4 have reset force torque spring 41.When using like this, after push rod push pedal 24 was shifted piston push pedal 13 onto the certain position location, push rod push pedal 24 can also reset under the effect of torque spring 41, disengages with piston push pedal 13.

Use: at first rotation triggers the lock 13 on lever 6 resistance arms 63, moves it the position that injection needs dosage.Then pull spanner lever 4, the 8 drive type piston push pedals 14 of suction medicine push rod are moved backward, drive rubber piston 51 simultaneously and move together, and medicinal liquid is sucked in the syringe 5, after reaching required dosage, the end face of driving lock 13 is squeezed in piston push pedal 14 blocks its bolt 13 that is insured.During injection, when the fork-shaped portion of power arm 61 front ends that trigger lever 6 or bar hole 2 are run into the carcass injection site, under the effect of lever force, trigger resistance arm 62 perks of lever 6, lock 13 stops braking, extension spring 11 is shunk and is driven piston push rod 52 and moves, thereby promote rubber piston 51 medicinal liquid is injected carcass.

Certainly; this utility model protection domain is not limited to the above-mentioned specific embodiment; it is so long as possess the using or replacing of various enforcement means of the present invention's connotation; concrete set-up mode as parts such as piston push pedals; the changes of the connected mode of parts such as extension spring etc. all should fall in this utility model protection domain.
