A kind of card punch easy to use
Technical field
The present invention relates to a kind of technical field of hardware, be specially a kind of card punch easy to use.
Background technology
Hole making drill is arranged on common electric drill, can carry out any cutting of circular hole, square hole, delthyrium, straight line, curve easily on the arbitrary surface such as plane, sphere of the various sheet material such as copper, iron, stainless steel, lucite, be one relatively more conventional in hardware products.
But, now hole making drill is commercially not out of this world, because the cooperation electric drill of hole making drill uses, cause causing hole making drill overall volume to become large, perforate is loaded down with trivial details, because stability not there will be perforate inaccuracy carefully simultaneously, cause the phenomenon training off hole, in life application, also higher to the required distance between the pore size punched and Kong Yukong, because traditional card punch perforating efficiency is low, the problems such as punch position is unfixing, user is when punching, can only feel to determine punch position according to self, the problems such as punching inaccuracy can be caused, unnecessary trouble is brought to user, we have proposed a kind of card punch easy to use for this reason.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose a kind of card punch easy to use.
Technical solution of the present invention is achieved in that a kind of card punch easy to use, the circumferential side wall comprising circular lid and vertically extend along lid excircle, the outer ring, bottom of described circumferential side wall is provided with sawtooth, the top of described lid offers vertical internal thread hole, the first threaded rod is provided with in internal thread hole, the top of described first threaded rod is provided with handle, bottom is installed with drill bit, and drill bit stretches out the bottom of circumferential side wall, the side of described circumferential side wall is installed with tolerance fixture, described tolerance fixture comprises regulating shaft, amount body shell, second threaded rod, positioner and slide calliper rule, described amount body shell is arranged on slide calliper rule, the middle part of described amount body shell offers vertical internal thread hole, the second threaded rod is provided with in internal thread hole, described regulating shaft is arranged on the top of the second threaded rod, the bottom of described second threaded rod arranges positioner, the side of the bottom surface of described positioner is provided with prominent point, the place of bottom center of described positioner is provided with locating cone.
Preferably, the height of described locating cone is greater than or equal to the height of prominent point.
Preferably, described prominent point has two, and two described prominent points are positioned on two relative sides of the bottom surface of positioner.
Preferably, described circumferential side wall is also provided with an observation port.
Preferably, described slide calliper rule are also provided with circular hole, and the quantity that described circular hole can be arranged is 3 to 5.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Card punch structure of the present invention is simply easy to use, by installing the drill bit of different size, can measure length in limit, pore size is surveyed on limit, simultaneously by being provided with positioner, as long as fix the first punch position, the function of punching continuously just can be realized, improve the accuracy of hole making drill, also the operation of convenient people and use, improve the efficiency of work, the good stability of this card punch punching simultaneously, also traditional card punch perforating efficiency is solved low, the problems such as punch position is unfixing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1 is structural representation of the present invention.
In figure: 1, lid; 2, circumferential side wall; 3, sawtooth; 4, the first threaded rod; 5, handle; 6, drill bit; 7, fixture is measured; 71, regulating shaft; 72, body shell is measured; 73, the second threaded rod; 74, positioner; 75, slide calliper rule; 8, prominent point; 9, locating cone; 10, observation port; 11, circular hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described.
As shown in Figure 1, a kind of card punch easy to use of the present invention, the circumferential side wall 2 comprising circular lid 1 and vertically extend along lid excircle, the outer ring, bottom of circumferential side wall 2 is provided with sawtooth 3, described circumferential side wall 2 is also provided with an observation port 10, the top of lid 1 offers vertical internal thread hole, the first threaded rod 4 is provided with in internal thread hole, the top of the first threaded rod 4 is provided with handle 5, bottom is installed with drill bit 6, and drill bit 6 stretches out the bottom of circumferential side wall 2, the side of described circumferential side wall 2 is installed with tolerance fixture 7, tolerance fixture 7 comprises regulating shaft 71, amount body shell 72, second threaded rod 73, positioner 74 and slide calliper rule 75, amount body shell 72 is arranged on slide calliper rule 75, the middle part of amount body shell 72 offers vertical internal thread hole, the second threaded rod 73 is provided with in internal thread hole, regulating shaft 71 is arranged on the top of the second threaded rod 73, the bottom of the second threaded rod 73 arranges positioner 74, the side of the bottom surface of positioner 74 is provided with prominent point 8, the place of bottom center of positioner 74 is provided with locating cone 9, the height of locating cone 9 is greater than or equal to the prominent height of sharp 8, prominent point 8 has two, and two described prominent sharp 8 are positioned on two relative sides of the bottom surface of positioner 74, slide calliper rule 75 are also provided with circular hole 11, and the quantity that circular hole 11 can be arranged is 3 to 5.
When the present invention uses, by pulling open tolerance fixture 7, amount of movement body shell 72 chooses applicable length, screw regulating shaft 71 again, because the bottom of the second threaded rod 73 arranges positioner 74, the side of the bottom surface of positioner 74 is provided with prominent point 8, the place of bottom center of positioner 74 is provided with locating cone 9, and the height of locating cone 9 is greater than or equal to the prominent height of sharp 8, tolerance fixture 7 is better fixed on to be perforated on object, the drill bit 6 chosen is arranged on the bottom of the first threaded rod 4, by drive first threaded rod 4, drill bit 6 is pierced the object that is perforated by turn handle 5, by being provided with sawtooth 3 on the outer ring, bottom of circumferential side wall 2, better can fix card punch, by being also provided with circular hole 11 on slide calliper rule 75, and the quantity that circular hole 11 can be arranged is 3 to 5, such design, make when punching, fix the first punch position, continuous punching can be realized, described slide calliper rule 75 can be used to measure simultaneously, be convenient for measuring, improve accuracy, ensure that the distance of punching is equal, structure of the present invention is simply easy to use, by installing the drill bit of different size, length can be measured in limit, pore size is surveyed on limit, as long as fix the first punch position simultaneously, just can realize the function of punching continuously, improve the accuracy of hole making drill, also the operation of convenient people and use, improve the efficiency of work, the good stability of this card punch punching simultaneously.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
