Detailed description of the invention
In order to deepen understanding of the present utility model, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, and this embodiment, only for explaining the utility model, does not form the restriction to protection domain of the present utility model.
As shown in Figure 1, DNA purification column dress film instrument of the present utility model, it comprises the body of a gun 5, cutter head 4 and push rod 6, the body of a gun 5 upper end is threaded handle 2, and the body of a gun 5 bottom to be threaded cutter head 4 by pad 3, arranges spring 7 and push rod 6 in the body of a gun 5, spring 7 is placed on push rod 6, the body of a gun 5 surface has a groove 8, installs to push away and turns round screw 1 in groove 8, pushes away to turn round screw 1 end and act on push rod 6.
Wherein, between the body of a gun 5 bottom and cutter head 4 upper surface, pad 3 is set, pad 3 arrange number, determine that push rod 6 releases the length of the edge of a knife, the different material of dress film is how many.
Shown in Fig. 5, push rod 6 is divided into bigger diameter end 61 and miner diameter end 62, and spring 7 is placed on miner diameter end 62, and spring 7 is against in the body of a gun 5 by cutter head 4, because the shape of cutter head 4 is sharp cone distal, bigger diameter end 61 has for pushing away the hole 63 turned round screw 1 and assign.
Shown in Fig. 4, the groove 8 pushing away and turn round screw 1 is assigned on the body of a gun 5 surface, and groove 8 comprises along the longitudinal part 81 in the body of a gun 5 direction and the curved portions 82 of establishing along the body of a gun 5 external peripheral surface ring.Push away and turn round the longitudinal part 81 of screw 1 at its groove 8 toward drop-down, then draw in curved portions 82, push away the most at last and turn round screw 1 active force and act on push rod 6, push rod 6 is released in the body of a gun 5.
With reference to figure 6, adopt dress film instrument of the present utility model, carry out dress film to DNA screen pipe, screen pipe suitable for reading 92 covers with lid 91, and screen pipe exports the similar funnel of 95 shape, stacks filter membrane 94, trim ring 93 in screen pipe 9 successively.The position length that push rod 6 exposes, determine that trim ring 93 is pressed into the depth in pipe, be applicable to different filter membranes, push rod 6 length exposed, corresponding is film; It is short that push rod 6 exposes, and corresponding is thick film.
Referring to figs. 2 and 3, DNA purification column dress film instrument is cut, the method for press mold:
A, when push rod 6 returns state, cutter head 4 subtend filter membrane 94, semicircle rotating down pressing, the film automatic safety cut is at cutter head 4 oral area;
B, cutter head 4 are aimed to be needed to fill screen pipe 9 mouth of pipe of film, pushes away to turn round screw 1 and make push rod 6 release the filter membrane 94 cut, and enters screen pipe 9 inner bottom part;
C, dial revolve push away turn round screw 1 make push rod 6 keep release after stationary state, for press-fiting filter membrane 94, trim ring 93;
D, press trim ring 93 after, oppositely revolve pushing and turn round screw 1, push rod 6 automatically resets under the effect of spring 7, continues next step action.
Adopt dress film instrument of the present utility model, structure is simple, and semi-automatic degree is high, and cut, press mold speed is fast, be firmly fixed on bottom screen pipe 9 by filter membrane 94, trim ring 93, can not produce waste product, qualification rate is high.
