Abstract
A hole puncher comprises an inner handle, an outer handle, a plurality of cylindrical drills with different diameters and the like. The hole puncher is characterized in that the drills are fixedly connected with the inner handle which is movably connected with the outer handle, the cylindrical drills with small diameters can be sequentially sleeved in the cylindrical drills with large diameters, each cylindrical drill is a cylinder, one end of the cylinder is arranged into a cutting edge which is slightly zigzag while the other end is fixedly connected with the inner handle via a round hole, a hollow groove is arranged at the center of the outer handle, two upper ends of the hollow groove are respectively embedded with a high-performance magnet, outer surfaces of the magnets are located on the same plane with the upper edge of the hollow groove, and the inner handle can be disposed in the hollow groove rightly. The hole puncher has the actual advantages that the puncher can not abrade hands of users, is labor-saving and high-efficient during punching, and has simple structure, low manufacturing and using cost and easy popularization.
Description
Technical field
The utility model relates to a kind of card punch, relates to a kind of card punch that can conveniently make up and punch and save labour specifically.
Background technology
Card punch is one of laboratory instrument commonly used, and old-fashioned card punch does not originally become decades, plays the hole and comes difficultly, and handle mill hand is easy to palm is ground bleeding blister if make a call to tens holes continuously.Chinese patent publication number: CN2034510 " the electronic card punch of rubber stopper " and Chinese patent publication number: CN101450492A " novel rubber plug puncher " are though improve to some extent to the problems referred to above, but complex structure, volume is big, and the cost height can not be accomplished staff one cover in college chemical experiment.
Summary of the invention
The purpose of this utility model is at above-mentioned contradiction, and a kind of card punch is provided, and it can solve this contradiction effectively, thereby improves perforating efficiency.
Technical solution of the present utility model is: a kind of card punch, comprise that interior handle, the outer handle cylindrical shape different with several diameters bore cutter etc., it is characterized in that: described brill cutter is fixedlyed connected with interior handle, interior handle and outer handle active link, the less cylindrical shape of diameter bore cutter and can pack into successively in the bigger cylindrical shape brill cutter of diameter.
Handle is that oval-shaped steel plate and center are provided with circular hole in described, and the diameter of this circular hole equals the outside diameter of cylinder that described cylindrical shape is bored cutter.It is to be arranged to the edge of a knife and blade portion is small zigzag at an end of a cylinder that described cylindrical shape is bored cutter, and the other end is fixedlyed connected by circular hole with interior handle.
Described outer handle profile is a spheroid, and its outer surface is provided with several projectioies; It is that cuboid, level cross-sectionn are oval-shaped dead slot that outer handle centre is provided with the forward cross section, a high-performance magnet is also respectively inlayed at two ends directly over this dead slot, the outer surface of magnet and the upper edge of this dead slot are in same plane, and above-mentioned interior handle can just in time be placed in this dead slot.
During use, the cylindrical shape that the selection bore is suitable is bored cutter and handle in it is inserted in the above-mentioned dead slot, the magnet of outer handle inside just firmly holds interior handle and can hole to rubber stopper, during tool changing, slightly firmly just cylindrical shape can be bored cutter and pull up and change the different cylindrical shape of another bore again and bore cutter and get final product.
The novel actual effect of this use is: do not grind hand during punching, save labour, the efficient height.The utility model is simple in structure in addition, manufacturing cost and use cost are all lower, very easily promotes.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: a kind of card punch, handle 5, outer handle 3 cylindrical shape different with several diameters are bored cutter etc. in comprising, it is characterized in that: described brill cutter is fixedlyed connected with interior handle 5, interior handle 5 and outer handle 3 active links, the less cylindrical shape of diameter bore cutter and can pack into successively in the bigger cylindrical shape brill cutter of diameter.
Described outer handle 3 profiles are spheroids, and its outer surface is provided with several projectioies 6; It is that rectangle, level cross-sectionn are oval-shaped dead slot that outer handle 3 centres are provided with the forward cross section, a high-performance magnet 4 is also respectively inlayed at two ends directly over this dead slot, the outer surface of magnet 4 and the upper edge of this dead slot are in same plane, and above-mentioned interior handle 5 can just in time be placed in this dead slot.
The novel actual effect of this use is: do not grind hand during punching, save labour, the efficient height.The utility model is simple in structure in addition, manufacturing cost and use cost are all lower, very easily promotes.
