Abstract
The utility model discloses a perforation device for plates, particularly a perforation drill bit. The utility model comprises a main rod and a cross shaft, wherein, the main rod is fixed on the middle position of the cross shaft, and one end of the main rod is provided with a center drill and the other end is a handle head which can be arranged on a motor. Both ends of the cross shaft are provided with antiskid-out devices, and both sides of the main rod are provided with blade fixed mounts which can move between the main rod and the antiskid-out devices along the cross shaft. Blades are fixed on the blade fixed mounts, and a position which is positioned under the cross shaft on the main rod is fixed with a protecting cover which is not rotated following the rotation of the main rod and can cover the whole cross shaft, the center drill and the blades. The middle position of the bottom of the protective cover is provided with a hole, the main rod can penetrate through the hole, and a fixing device for stopping the protective cover sliding downwards is arranged under the protective cover along the main rod. The perforation drill bit can prevent bits from flying following the wind and sprinkling on the ground in perforating, and can prevent the blades from flying out to injuring people. Thus, the operation is safer, cleaner and more convenient.
Description
Technical field
The utility model relates to a kind of sheet material boring device, more particularly, is a kind of opening bit.
Background technology
As everyone knows; what the sheet material perforate was the most frequently used is the electric drill of band blade; the opening bit of electric drill and alignment blade need the position of perforate; open motor and just can begin perforate; in the perforate process; the going deep in sheet material along with opening bit and blade; sheet material is cut off or changes broken formation crumb; crumb extrusion board surface around opening bit and the blade; at this moment general drill bit is without any safeguard measure; crumb rises or spreads everywhere with the wind; particularly during the position perforate above operating personnel such as ceiling, the crumb that scatters can drop on one's body the operating personnel; on the head; particularly on the eyes, have a strong impact on operation; and bring dangerous to operating personnel; unhygienic; after repeatedly using for a long time, blade can rupture, and the blade of fracture is owing to the tangential force effect meeting of rotation flies out towards periphery; easily produce operating personnel or surrounding population are damaged, or to the destruction of object on every side.
The utility model content
At the technical problem that exists in the prior art, the utility model provide a kind of can prevent perforate the time crumb rise with the wind, spread everywhere or influence operating personnel or surrounding population, and the blade that prevents from the to rupture opening bit that flies out and hurt sb.'s feelings.
The utility model is for reaching above purpose, be to realize: a kind of opening bit is provided by such technical scheme, comprise mobile jib and transverse axis, mobile jib is fixed on the transverse axis centre position, mobile jib one end mounting center is bored, the other end is for being installed on the button on the motor, the transverse axis two ends have the anti-skidding device, the blade holder that can move along transverse axis is equipped with on mobile jib two limits between mobile jib and anti-skidding device, be fixed with blade on the blade holder, be positioned at the transverse axis lower position on the mobile jib and be fixed with a protective cover that does not rotate and can cover whole transverse axis and centre drill and blade with mobile jib, protective cover bottom interposition is equipped with a hole that can allow mobile jib pass, and the protective cover below is equipped with the fixture that stops protective cover to glide along mobile jib.
As a kind of improvement of the present utility model, bearing is installed in protective cover bottom centre hole.
As another improvement of the present utility model, the fixture top that stops protective cover to glide is equipped with spring around mobile jib, and fixture can be the nut of setting one's teeth on edge.
As another improvement of the present utility model, the protective cover upper edge can be equipped with anti-skidding sideband, and anti-skidding sideband can be a rubber.Protective cover can be made for all or part of transparent pmma material simultaneously.
Adopt the opening bit of said structure, crumb rises to scatter everywhere with blade with the wind and flies out and hurt sb.'s feelings in the time of preventing perforate, makes safer, the cleaning, more convenient more of operation.Simultaneously, the bearing protection cover is housed makes mobile jib rotate more freely, do not influence the fixing, safe and reliable of protective cover.Spring can make protective cover comparatively be securely fixed in by on the sheet material of perforate, is difficult for sliding, and the sideband of protective cover upper edge has adhesive attraction, can prevent that also protective cover from sliding on by perforate sheet material.The convenient operation of protective cover of adopting all or part of transparent lucite to make.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described.
Description of drawings
Fig. 1 is the schematic diagram of the opening bit of prior art.
Fig. 2 is the schematic diagram of opening bit of the present utility model.
The specific embodiment
Fig. 2 shows and adopts opening bit of the present utility model, comprise mobile jib 2 and hexagonal transverse axis 1, mobile jib 2 is fixed on the centre position of hexagonal transverse axis 1, mobile jib 2 upper ends fixed installation centre drill 3, the lower end is for being installed on the triangle button 4 on the motor, blade holder 6 is equipped with on mobile jib 2 two limits, be fixed with blade 5 on the blade holder 6, a screw 7 is fixed at hexagonal transverse axis 1 two ends respectively, to prevent that blade holder 6 from skidding off hexagonal cross bar 1, blade holder 6 can move between mobile jib 2 and screw 7 along hexagonal transverse axis 1, be positioned at the fixing protective cover 8 of hexagonal transverse axis 1 lower position on the mobile jib 2, perforate in the middle of protective cover 8 bottoms, mobile jib 2 passes this hole, protective cover 8 can cover whole hexagonal transverse axis 1 and centre drill 3 and blade 5, protective cover 8 belows stop protective cover to glide the opening bit of this spline structure along mobile jib fixing device for installing 12, crumb rises to scatter everywhere with blade with the wind and flies out and hurt sb.'s feelings in the time of preventing perforate, makes operation safer, more clean, more convenient.
Protective cover 8 bottom centre holes are equipped with bearing 10, and like this, bearing 10 rotates with mobile jib 2, and protective cover 8 is motionless, makes mobile jib 2 rotate more freely, does not influence the fixing of protective cover 8, and are safe and reliable.
The fixture 12 of protective cover 8 belows can be the nut of setting one's teeth on edge, and around mobile jib one spring 11 is installed above the nut of setting one's teeth on edge, and protective cover 8 is securely fixed in more by on the sheet material of perforate.
Protective cover 8 is made for transparent lucite, can see through that protective cover is clear find out the position that needs perforate, handled easily, and protective cover 8 upper edges can be equipped with anti-skidding sideband 9 simultaneously, and anti-skidding sideband 9 can be a rubber.
