Accommodating groove is offered on plate, is used to support the syringe needle of syringe；
Propulsion device comprising trigger, reset spring and pushing plate, the trigger are hingedly on the housing, described multiple
Position spring one end is connected on the trigger, the other end connects on the housing, for driving the trigger to reset；It is described to push away
It include the rear baffle for promoting rack gear and being arranged on the propulsion rack gear into plate, the rear baffle is used to be resisted against the work of syringe
On stopper rod, the propulsion rack gear is slidably disposed in the support portion, is offered on the trigger and the propulsion rack gear
The arc-shaped gear matched, when the trigger rotation, the arc-shaped gear drives the propulsions rack gear to move.
More preferably, sliding slot is offered in the support portion, the two sides for promoting rack gear are provided with to match with the sliding slot
The sliding block of conjunction, the sliding block are slidably disposed in the sliding slot.
It more preferably, further include pressing plate, the side of the pressing plate is hinged in the support plate, and the pressing plate is in the shape of the letter V, institute
State pressing plate overturning when can gland on the needle tubing of syringe.
The utility model provides a kind of syringe accessory device, pushes trigger, and trigger drives arc-shaped gear rotation, and arc-shaped gear turns
It is pushed in dynamic process and promotes rack gear and then drive piston rod Forward injection, since handle is big compared with piston rod, identical active force
Under, since handle forced area is big, pressure is small, therefore can substantially reduce the injury to operator's palm of the hand, passes through reset spring
It may be implemented to automatically reset, avoid the need for artificial post-tensioning and promote trouble caused by rack gear.

Specific embodiment
With reference to the accompanying drawing, a specific embodiment of the utility model is described in detail, it is to be understood that this
The protection scope of utility model is not limited by the specific implementation.
As shown in Figure 1 to Figure 3, a kind of syringe accessory device provided by the embodiment of the utility model, comprising:
Shell 10 includes at least handle 11 and the support portion 111 positioned at 11 upper end of handle, the support portion 111
The end of the support plate 14 for being used to support syringe with one, the support plate 14 is provided with for being resisted against front end of the syringe needle
Front apron 12 offers accommodating groove on the front apron 12, is used to support the syringe needle 01 of syringe；
Propulsion device 20 comprising trigger 21, reset spring 22 and pushing plate, the trigger 21 are hinged on the shell 10
On, described 22 one end of reset spring is connected on the trigger 21, the other end is connected on the shell 10, described for driving
Trigger 21 resets；The pushing plate includes the rear baffle 23 for promoting rack gear 24 and being arranged on the propulsion rack gear 24, after described
Baffle 23 is used to be resisted against the piston rod of syringe, and the propulsion rack gear 24 is slidably disposed in the support portion 111,
The arc-shaped gear 211 matched with the propulsion rack gear 24, when the trigger 21 rotates, the arc are offered on the trigger 21
Tooth 211 drives the propulsion rack gear 24 mobile.
Specifically, as shown in figure 3, offering sliding slot 13 in the support portion 111, the two sides setting for promoting rack gear 24
There is the sliding block matched with the sliding slot 13, the sliding block is slidably disposed in the sliding slot 13.
It further include pressing plate 30, the pressure in order to enable syringe to be stably placed in support plate 14, in the present embodiment
