Wherein, described sample introduction groove 2 is for placing the gathering sill of kapillary 4, and operating personnel are placed into kapillary 4 on brace table 15 by sample introduction groove 2.
Wherein, described brace table 15 slides on horizontal guide rail 12, is advancing with centrifugal postcapillary 4 being advanced in handgrip 18 under linear electric motors 13 drivings.
Wherein, described spring clamp 14 coordinates with the motor shaft of linear electric motors 13 with propelling, and motor shaft enters in spring clamp 14, spring clamp 14 is opened, and at this moment kapillary 4 can be placed on spring clamp 14, when motor shaft leaves spring clamp 14, spring clamp closes 14 and closes, and can clamp kapillary 4 like this.
Beneficial effect
The beneficial effect of the mechanical sampling system of dry type blood cell analysis device of the present invention is:
Compare with the sampling system of existing analytical equipment, adopt and advance with linear electric motors 13, rotation linear electric motors 17, horizontal slide rail 12 actings in conjunction in kapillary 4, sample rate and the anti-seismic performance of device have greatly been improved, further improved system running speed, fully save analysis required time, improved detection efficiency.
