The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
The blade card punch of the utility model embodiment, improves for the deficiency of existing blade card punch.With reference to figure 1, it is existing blade card punch structural representation.
Existing blade card punch comprises the first hinged caliper 101 and the second caliper 102, the first caliper 101 and the second caliper 102 include jaw and handle, the jaw end of the first caliper 101 is provided for the vane frame 104 that the jaw end of punching arm 103, the second calipers 102 of blade punching is provided for placing blade to be punched.The through hole (not shown in figure 1) coordinating with described punching arm 103 is set in described vane frame 104.
With reference to figure 2, it is existing blade card punch vane frame schematic diagram.
Existing blade card punch is when carrying out blade punch operation, need operator's Manual blades card punch on the other hand, another hand is taken centrifuge tube, the mouth of pipe of centrifuge tube is aimed to the bottom of the through hole 205 in vane frame 204, the handle of described the first caliper and the second caliper held with a firm grip makes its jaw closure, punching arm 203 passes and treats the punching of punching blade from through hole 205, and the blade sample after punching falls in centrifuge tube.
For the operating process of existing blade card punch, once operator make a fault, by very easily cause blade sample omission, drop, cause damage; Meanwhile, the size of blade punching is also restricted, and the size of punching is less, above-mentioned omission more easily occurs, drop phenomenon.
With reference to figure 3, it is the blade card punch structural representation of the utility model embodiment.
A kind of blade card punch that the utility model embodiment provides, comprises the first hinged caliper 301 and the second caliper 302, and described the first caliper 301 and the second pincers 302 bodies include jaw and handle; The jaw end of described the first caliper 301 is provided for the punching arm 303 of blade punching, the jaw end of described the second caliper 302 is provided for placing the vane frame 304 of blade to be punched and the draw-in groove 306 for fixing centrifuge tube, and the through hole (not shown in Fig. 3) coordinating with described punching arm 303 is set in described vane frame 304; The handle of described the first caliper 301 and the second caliper 302 held with a firm grip makes its jaw closure, and described punching arm 303 passes and treats the punching of punching blade from described through hole, and the blade sample after punching falls in the centrifuge tube being fixed on described draw-in groove 306.
Wherein, described punching arm 303 is cylindrical.Columniform punching arm can be produced circular blade sample, attractive in appearance and facilitate the follow-up operation to blade sample.Further, the diameter of described cylindrical punching arm 303 is 3mm, and the punching diameter of existing blade card punch is 6mm, and more the blade sample of minor diameter can improve experimental precision.
With reference to figure 4, it is the blade card punch jaw place schematic diagram of the utility model embodiment.
When the blade card punch of use the utility model embodiment carries out blade punch operation, first centrifuge tube 401 is fixed on draw-in groove 406, the mouth of pipe of the described centrifuge tube 401 after fixing is near the through hole in vane frame 404 (not shown in Fig. 4) bottom.Then blade 402 to be punched is placed in vane frame 404, the handle of two calipers held with a firm grip makes its jaw closure, punching arm 403 is treated punching blade 402 through through hole and is punched, and the blade sample after punching falls and directly enters in centrifuge tube 401 from through hole bottom.
Wherein, described vane frame 404 arranges a groove, and blade to be punched is placed in described groove, and described recess width is 5mm.Take conventional maize leaf in experiment as example, existing blade card punch, can only be simultaneously to two maize leafs punchings for placing the only wide 2mm of groove of blade to be punched; And the blade card punch of the present embodiment can once be put at most 4-5 sheet blade, improved greatly blade perforating efficiency.
Use the blade card punch of the utility model embodiment to carry out blade punch operation, only need hand of operator to complete, improved operating efficiency.Meanwhile, avoid the blade sample that operator's operate miss causes to omit, drop, further, in the situation that guaranteeing work quality, can carry out the blade punching work that size is less.
As an embodiment, between the jaw of described the first caliper and the second caliper, be provided for the spring 307(of auxiliary playback with reference to figure 3).By described spring 307 is set, make to complete after a punch operation, the first caliper and the second caliper can return to initial position fast, have prepared work next time.In addition, in blade punching process, the setting of spring 307, evenly exerting oneself of operator, makes operator's the action of holding with a firm grip milder, is convenient to grasp dynamics, has also improved drilling quality.
Further, on the handle of the first caliper and the second caliper, Anti-slip cover is all set, to prevent that operator from blade punching process, skidding occurring, and causes unnecessary loss.
The draw-in groove of the jaw end of the second described caliper is U-shaped draw-in groove.U-shaped notch is simple, and operator inserts centrifuge tube in U-shaped draw-in groove, and the edge of the centrifuge tube mouth of pipe will be stuck in U-shaped draw-in groove upper end, realizes the fixing of centrifuge tube.
Those of ordinary skill in the field are to be understood that: the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle; any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
