[0034] This case also discloses a blood separator using the above-mentioned monitoring box holder.

[0035] The specific use method of the monitoring box holder described in this case is as follows: S1, put into the monitoring box: As the instruction manual Fig. 9 As shown: Place the monitoring box 7 from top to bottom between a pair of limiting bosses 91 of the bottom plate 9; The monitoring box 7 squeezes the compressed upper plate 32 and the compressed inclined surface 33 of the fixed clamp arm 3, so that the fixed clamp arm 3 and the central rotating shaft 2 deflect outward around the axial blind hole 123; S2, fixed monitoring box: The bottom of the monitoring box 7 abuts against the bottom plate 9; The damping compression spring 46 squeezes the spring baffle 45, the damping connecting rod 44, the sliding outer ring 43, and the arc groove 47; The arc groove 47 acts on the arc inclined platform 42 to drive the damping circular shaft 41, the central rotating shaft 2, and the fixed clamp arm 3 to deflect inwardly; The compressed upper plate 32 is locked above the monitoring box 7 to fix it.

[0036] As a further implementation scheme, the deflection damping of the fixed clamp arm 3 can also be adjusted: Rotate the adjustment handle 62, the adjustment spindle 61, and the adjustment screw 63 to drive the internal threaded tube 64 and the anti-rotation key 65 to move in the left and right directions; Adjust the compression amount and elastic force of the damping compression spring 46 under normal conditions, and then adjust the extrusion stress of the spring baffle 45, damping connecting rod 44, sliding outer ring 43, and arc groove 47 on the arc ramp 42, and adjust the deflection damping of the arc ramp 42, fixed clamp arm 3, and central rotating shaft 2.

[0038] Based on the above improved technical solution, the monitoring box retainer described in this case can achieve a double locking function: The torsion terminal 54, the torsion mandrel 53 and the locking screw 55 are rotated, and the locking screw 55 acts on the radial connecting rod 57 to drive the locking sliding ring 56 and the locking plug rod 58 to move leftward; If the fixed clamp arm 3 is already in a vertical position at this time, When the locking rod 58 is directly inserted into the locking narrow groove 523, the monitoring box 7 is completely fixed and locked.

[0039] The locking rod 58 acts on the transition inclined groove 522, thereby driving the reset groove 52, the central rotating shaft 2, and the fixed clamp arm 3 to deflect inwardly.
