Detailed description of the invention
As it is shown in figure 1, a kind of hand drill formula donkey skin sample sampler, including electric drill and drill bit sampler；Described electric drill includes electric drill body 1 and drill jig 2, electric drill body in the present embodiment adopts lithium cell charging formula power drill, so can eliminate power line and device is used the restriction of environment, namely can also carry out donkey skin sampling work in place outside when there is no external power source；Described drill jig adopts three-pawl type, and described drill jig is arranged on the front end of described electric drill body.
As shown in Figures 2 and 3, described drill bit sampler includes hollow boring bit 3, ejecting mechanism and drillstock 4, described hollow boring bit 3 adopts cylindrical structure, the rear end of described hollow boring bit 3 is solid construction, described hollow boring bit other parts adopt hollow cylindrical structure, the hollow hole referred to along cylinder axis direction of described hollow boring bit 3；The top on the face of cylinder of described hollow boring bit 3 is symmetrically arranged on two with sliding tray 5.
As shown in Figure 3 with shown in Fig. 4, described ejecting mechanism includes depression bar 6, montant 7, spring 8, spring anchorage bracket 9 and ejects end cap 10；Described depression bar 6 is a rectangular shaft, and the length of depression bar 6 is more than the described cylindrical diameter of hollow boring bit, and the two ends of described depression bar 6 are slidably disposed in sliding tray 5；Described montant 7 is welded on the lower end in depression bar 6 centre position, adopts cylindrical structure；Described ejects end cap 10, is a disc, is welded on the lower end of described montant 7；Described spring anchorage bracket 9 is a rectangle cross-arm, and the two ends of spring anchorage bracket 9 are fixed in the housing of hollow boring bit 3, and the centre position of described spring anchorage bracket 9 is provided with the circular port for montant 7 traverse；Described spring 8 is arranged on spring anchorage bracket 9 and ejects between end cap 10, and the upper end of described spring 8 is fixedly connected on the lower end of spring anchorage bracket 9, and the lower end of described spring 8 is fixedly connected on the upper end ejecting end cap 10；Described spring 8 is sleeved on the bottom of montant.
The edge of the front end disc of described hollow boring bit 3 is provided with circular saw 11, after device is opened, making hollow boring bit 3 be directed at donkey skin sample, described hollow boring bit 3 will drive circular saw 11 circumgyration incision donkey skin, donkey skin sample be involved in therewith hollow boring bit 3 hollow in.
After donkey skin is sampled by device, adopting ejecting mechanism, will be left in drill bit sky, the donkey skin sample during 3 cylindrical structures are hollow takes out.Concrete mode is, depresses depression bar 6, and at this moment depression bar 6 will move down in sliding tray 5, and is driven by montant 7 and eject end cap 10 and think lower movement, being ejected from the front end of hollow boring bit 3 by donkey skin sample until ejecting end cap 10, stopping depression bar being pressed, unclamping depression bar；At this moment, eject end cap 10 and move up due to the pulling force by spring 8, and drive depression bar 6 to move up along sliding tray 5 by montant 7, until ejecting mechanism returns to initial state.
Described drillstock 4 is cylindrical solid structure；One end of drillstock 4 is fixedly welded on the center of the solid construction end face of described hollow boring bit 3 rear end, and the other end of described drillstock 4 is fixing to be installed in drill jig 2.The mode that is installed of drillstock 4 and drill jig 2 is identical with the mode that is installed of normal drill bit of the prior art Yu common electric drill.
Described hollow boring bit 3 is divided into the multiple hollow boring bit of different thicknesses diameter dimension, but identical with drillstock 4 size dimension of described multiple hollow boring bit welding.So according to the same day sampling number, it is necessary to change different-diameter size hollow boring bit 3 time, operation drill jig 2 more bit change sampler step just relatively easy.
After a sample just sampling, it is possible to drill bit sampler is put into ethanol and soaks, it is prevented that the mixing of DNA composition between sample, then carry out sampling next time again.
