Description

A kind of vaccinating pen

Technical field

The utility model relates to a kind of fungi vaccinating pen, particularly a kind of vaccinating pen that inoculating needle, inoculation spoon and transfering loop are combined.

Background technology

The loop-carrier that Chang Yaoyong is different in the fungi laboratory connects bacterium, connect behind the bacterium since not the thing as test-tube stand can deposit, so usually just with their bulk storages one side at experiment table.So not only take up space, and easily make it contaminated.Moreover, portable type is also inconvenient, and easily loses.

Summary of the invention

The utility model is for the defective of above problem technique scheme, and the technical problems to be solved in the utility model provides a kind of vaccinating pen that inoculating needle, inoculation spoon and transfering loop are combined.

For reaching above purpose, be achieved through the following technical solutions:

A kind of vaccinating pen comprises and eliminates button, selected slide block, a body, spring, inoculation pen core and the pen cap, eliminates button and is installed on pen end with it; Eliminating button is that ladder is cylindric; Pen with it end is provided with the locating slot that cooperates for elimination button step surface; Eliminate button step surface lower end column part and be provided with axially directed groove, the guide path lower end is provided with radial ringed locating slot, and the annular positioning groove lower end is provided with fixture block; Selected slide block is positioned in the guide path, and the inboard, upper end is provided with the circular-arc projection that cooperates with annular positioning groove, and the upper end arranged outside is stirred projection; Pen with it end is provided with the bar hole that stretches out and slide be used to stirring projection; Eliminate button fixture block upper surface and be equipped with positioning disc; Positioning disc is provided with the through hole corresponding with the guide path position; Spring is nested with on selected slide block, and is positioned over and stirs between projection and the positioning disc; The through hole that the inoculation pen core passes positioning disc is fixed on selected slide block lower end; The pen cap is fixed in a body lower end by screw thread; Guide path quantity is no less than 3; The inoculation pen core is divided into inoculating needle, inoculation spoon and transfering loop;

Owing to having adopted technique scheme, the utility model is combined the formation pen core with inoculating needle, inoculation spoon and transfering loop, then realizes the selection of every kind of different pen cores by the cooperation between selected slide block and the elimination button; Can save like this parking space of loop-carrier, and easy to carry, prevent that vaccinating pen is contaminated or damage, and conveniently select.

Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technique means of the present utility model, and can be implemented according to the content of specification sheets, and for above and other purpose of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and the cooperation accompanying drawing, be described in detail as follows.
