Specific embodiment

Following specific embodiments are only the explanation to the utility model, are not limitations of the present invention, this Field technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, But as long as all by the protection of Patent Law in the scope of the claims of the utility model.

Embodiment, as shown in Figure 1, 2, mental section brace formula perforating device, existing mental section perforating device is all Directly punched using drill bit, when beat hole be less than 1cm when, effect or pretty good, but when beat diameter for 1.5-3cm this When kind of large hole, the effect of punching with regard to it is bad too, and be easy so that profile itself goes wrong, in addition, thick drill bit The motor needed when drive also wants relatively high power, and operation when is not easily controlled, and people carrys out operational safety also and have certain The problem of, it is based on this, the application devises new perforating device: including base 1, there is motor, the motor in the base 1 Motor shaft be connected with the output shaft 2 for extending downwardly the base 1, in general existing equipment, between motor shaft and output shaft Both can be connected by clutch or slowing-down structure, drill chuck 3 is installed on the output end of the output shaft 2, it is described The drill bit 4 extended downwardly is folded on drill chuck 3, the lower part of the drill bit 4 is the bore portion 41 with flank, the drill bit 4 top is the clamping part 42 with the upper end integrally connected of the bore portion 41, and the upper end of the clamping part 42 is folded in described In drill chuck 3, these are all conventional existing designs, and main innovative design is, the clamping part 42 is located at 3 He of drill chuck The cylindrical blade 5 for being looped around 41 periphery of bore portion is also equipped on part between bore portion 41, the cylindrical blade 5 Downward, and the size of the drill bit 4 of the application is preferably smaller than 1cm to the edge of a knife 50 namely the diameter of bore portion 41 needs to be less than 1cm, excellent Choosing is 0.5cm or so, and the race diameter of cylindrical blade 5 just be preferably 1.5-3cm, according to it is required actually punch it is straight Diameter size requirements carry out selection setting, because the hole finally to be opened up is directly related to 5 outer ring size of cylindrical blade.This Shen The hole that structure please beats bore portion 41 is the hole of a positioning, and the hole that cylindrical blade 5 is cut is only real institute The hole to be processed.

Further design: the edge of a knife 50 of the cylindrical blade 5 is formed by several sawtooth of shape arranged in a ring, the saw The tooth tip of tooth is downward, naturally it is also possible to select the flat edge of a knife；

The extreme lower position of the cylindrical blade 5 is higher than the extreme lower position of the bore portion 41, that is, bore portion 41 can be first Encounter mental section, specific operating process is as follows:

This perforating device is most preferably suited to opening up for the mounting hole of hollow mental section, firstly, downward by drill bit, opening Motor is opened, the both hands of people are helped on 1 side wall of base and embraced, slowly vertical decline whole device, so that bore portion 41 is first touched To mental section, then to whereabouts, so that bore portion 41 first drills out the location hole at a center, bore portion 41 can be maintained at the hole In, then, whole device continues to have whereabouts in arms with hand, until the edge of a knife 50 of cylindrical blade 5 can encounter mental section and due to It is rotated when also will form cutting print, and the both hands of people do counterclockwise while having base 1 in arms or clockwise wave Movement, and preferably there are less than or equal to 20 degree inclination angles to be advisable with vertical direction, amplitude can be too big, not so will affect the hole to be opened up Quality, certainly at the same time, base 1 are also required for the displacement fallen, and rocking action 1-2 circle, this is base metal profile Desired hole is cut by cylindrical blade 5, at this point, base 1 is put into vertical shape, is then further fallen, in metal The hole of profile formation up and down is penetrated through on profile, so the hole that cylindrical blade 5 opens up is only really to be opened up Hole, the wall as far as possible of cylindrical blade 5 is thin namely the thickness of its outer ring and inner ring diameter wants Bao Yiding, and control is within 0.2cm It is selected preferably and again according to the thickness of mental section, a bit thick mental section can choose 5 wall thickness of cylindrical blade a bit 's.

Its preferred design scheme, the clamping part 42 are fixed on the part between drill chuck 3 and bore portion 41 One, in the positioning disc 6 for laying flat shape, can be fixed in the above by welding, and the cylindrical blade 5 is connected to described On positioning disc 6；

The top of the cylindrical blade 5 be welded be looped around 5 periphery of the cylindrical blade in the annular for laying flat shape Mounting disc 7, it is described annular mounting disc 7 be detachably connected on the positioning disc 6；

The diameter of the positioning disc 6 is greater than the diameter of the excircle of the annular mounting disc 7, and the two center is phase up and down Face is advisable；

Several positioning holes 60 up and down are offered on the positioning disc 6, are opened up in annular mounting disc 7 corresponding Hole, detachable connection method can be carried out by bolt, nut between the two, be conveniently replaceable various sizes of cylinder-shaped knife Piece 5 or same size are used for a long time not reusable blade etc., and positioning hole 60 is centered on the center of circle of positioning disc 6 Circumferentially array distribution and the positioning holes 60 of the inside and outside circumference array shape arranged of at least two circle of formation, more outer Circle-Array The positioning hole 60 of column is used for the bigger cylindrical blade 5 of race diameter.

The lateral wall of the base 1 is fixed with two points of left and right on the lateral wall in upright cylindric and described base 1 The arc convex portion 10 not helped for the centre of the palm of left and right palm, the hand of such people can be embraced above, be operated more comfortable；

The position that the lateral wall of the base 1 is located at arc convex portion 10 is further fixed on the hangers to recline for the palm back of palm 11, the hangers of cortex can be used；

The surface in the arc convex portion 10 is covered with one layer of flexible massage layer 12, and flexible massage layer 12 can use rubber system At, and the recess imitated in palmistry can be set in surface, and making to go smoothly, it is more comfortable above to be placed on.
