Embodiment

For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and accompanying drawing further Explanation, the content that embodiment refers to not to restriction of the present utility model.

In description of the present utility model, it is to be understood that term " on ", " under ", "front", "rear", "left", "right", The orientation or position relationship of the instruction such as " top ", " bottom ", " interior ", " outer ", " clockwise ", " counterclockwise " are based on shown in accompanying drawing Orientation or position relationship, be for only for ease of description the utility model and simplify and describe, rather than instruction or imply signified Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that new to this practicality The limitation of type.

In addition, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint relative importance Or the implicit quantity for indicating indicated technical characteristic.Term " multiple " refers to two and two or more, in the utility model Description in, unless otherwise prescribed with limit, term " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be Mechanical connection or electrical connection or the connection of two element internals, can be joined directly together, can also pass through intermediary It is indirectly connected, for the ordinary skill in the art, the concrete meaning of the term can be understood as the case may be.

As shown in figures 1 to 6, a kind of culture medium card punch, including body 3, cut-out silk 1, remove post 2, by pressing spring 5 and clear Except button 7, the body 3 is hollow circular-tube, including upper tube body 3a and lower tube body 3b, and the upper tube body 3a and lower tube body 3b are used Threaded connection, the lower tube body 3a is interior to be provided with spacing dividing plate 8, and the lower tube body 3a sides are provided with three installations of split key 9 Hole, the lower tube body 3a bottoms are provided with steam vent 11；The removing post 2 is cylinder, and its cross section is slightly less than the body 3 Cross section, the post 2 of removing are movably arranged on close to the position of bottom in body 3, and its bottom is fixedly connected with cut-out silk 1, and it is pushed up Portion is fixedly connected with the lower axle 4e of toggle 4；The toggle 4 include upper axle 4a, crank 4b, crank-pin 4c, Connecting rod 4d and lower axle 4e, the upper axle 4a pass through located at lower tube body 3b tops spacing dividing plate 8 and with upper tube body 3a Remove button 7 to be connected, the connecting rod 4c of the toggle 4 passes through mounting hole and flexible connection located at lower tube body 3a sides Split key 9, the split key 9 are provided with two guide rods, in the guide rod insertion mounting hole, the split key 9 with Back-moving spring 10 is provided between lower shell 3b, is provided between the removing button 7 and spacing dividing plate 8 and presses pressing spring 5.The technical program Punching and excision function that simple button press completes culture medium are realized, not only alleviates the work complexity of user, Also effectively prevent bad operation in cutting process simultaneously, substantially increase the quality of perforate, it is ensured that each bore edges and Bottom all smooth evens, and the design of steam vent, effectively solve the air bag phenomenon often occurred in drill process, also greatly Improve the success rate of punching.

As further improvement of this embodiment scheme, when button 7 is removed in pressing, the removing bottom end face of post 2 can be stretched Go out to outside lower tube body 3b.It so may insure to need the culture medium removed completely clear in the case where removing the pushing of post 2 in card punch Remove.It should be noted that to realize above-mentioned technique effect, the work of active strokes, toggle 4 for removing button 7 The position or length of dynamic stroke, removing post 2 in body 3 etc. is required for doing corresponding limitation（Active strokes >=crank of button The distance of the active strokes of connecting rod >=removing column bottom end face and lower tube body end）, for example, can be clear by above-mentioned part design Except column bottom is apart from lower tube body bottom 1cm, it is 1.5cm that maximum of the toggle 4 in body 3, which moves downward stroke, clearly It is 1.5cm except button 7 moves downward stroke, can ensures that culture medium residuum can be cleared out of body 3 by removing post 2；As foregoing In one's power, corresponding design should can be made according to thinking of the present utility model as those skilled in the art, it is just few herein Repeat.

As further improvement of this embodiment scheme, when pressing split key 9, the removing post 2 can be around its own axle Line rotates 180 degree.Similarly, post is removed when pressing split key 9 to realize to rotate 180 degree around own axes, it is also desirable to cutting The movement travel of disconnected button 9 and toggle 4 do necessary restriction, such as split key 9 is along its guide rod to body 3 The range of inner side pressing have to be larger than the length of twice of crank-pin.

As further improvement of this embodiment, the upper axle 4a and spacing dividing plate 8 via clearance coordinate.Using gap Cooperation may insure to have certain free degree when toggle is run in cylinder but be unlikely to excessively to loosen, and avoid When pressing split key crank up campaign can not be completed because gap is excessive.

As the preferred scheme of the present embodiment, split key surface is provided with slip-resistant texture.The punching of culture medium is inherently One more fine work, the design of slip-resistant texture can be effectively prevented from slipping during pressing split key so that Punching failure.

As further improvement of this embodiment, the upper axle and remove button between be additionally provided with sliding block described in sliding block with it is upper Body gap coordinates, and the sliding block is fixedly connected with upper axle.When carrying out rupturing operation room, if finger pinned by mistake removing by Button, then toggle damage is easily caused, the design of sliding block can avoid the generation of this problem completely, while subtract significantly Resistance during few crank and connecting rod movement.

As further improvement of this embodiment, the cut-out silk is " T " font wire.Certainly, it is described to cut off silk also Other shapes can be arranged to, but its function is allowed for realizing and completed in the case where removing the rotating in a circumferential direction of post to culture medium level The function of direction cutting, is not just repeated herein.

Further improvement as the present embodiment：The lower tube body bottom inner surface is provided with the ring vertical with body axis Connected in star, the cut-out silk are provided with the annulus with annular groove formed objects.Cut-out silk provided with annulus has more excellent Guidance quality, it can be ensured that during cut-out be not in cut-out silk torsional deflection and cut off failure.

Above-described embodiment is the preferable implementation of the utility model, and in addition, the utility model can be with other sides Formula is realized, any on the premise of the technical program design is not departed from obviously to replace in protection model of the present utility model Within enclosing.

In order to allow those of ordinary skill in the art more easily understand the utility model relative to prior art improvement it Place, some accompanying drawings of the present utility model and description have been simplified, and for the sake of clarity, present specification is omitted one A little other elements, those of ordinary skill in the art should be aware that these elements omitted also may make up in of the present utility model Hold.
