Specific implementation mode
In the following, in conjunction with attached drawing, the hand-held dispensation apparatus of the present invention is described in detail.
The hand-held dispensation apparatus of the present invention comprising：Injector cartridge housing unit, injector handle clamping unit
40。
Injector cartridge housing unit is used to be fixedly mounted the cylinder of syringe 30, is formed with for syringe in its front end
The first opening 11 that the nipple of 30 barrel front end passes through, be formed in its back-end piston rod for syringe 30 by second
Opening 23.The first magnet 12 is provided in injector cartridge housing unit.
Injector handle clamping unit 40 is used to fixedly be held in the handle of the piston rod of syringe 30；Syringe hand
The second magnet 41 is provided on handle clamping unit 40.
First magnet 12 attracts each other or repels with the second magnet 41, so that the piston rod of syringe 30 is pushed into
Or extraction.
At least one in first magnet 12 and the second magnet 41 is electromagnet, which can converted magnetic pole as needed
Direction is achieved in the conversion of attraction and repulsion.
As optimal embodiment, the first magnet 12 is electromagnet, and the second magnet 41 is permanent magnet.
Preferably, the first magnet 12, the second magnet 41 are electromagnet.
Injector cartridge housing unit includes front assembly 10 and rear component 20；Forward and backward component is removably combined together,
The cylinder of syringe 30 is held in injector cartridge housing unit.
Forward and backward component is threadedly removably combined together.As shown in Fig. 2, the rear end of front assembly 10 is formed
