Inventor has found that existing cornish bit is at least suffered from the drawback that under study for action：Existing cornish bit can only be to straight
The hole of cylindricality is processed, and use range is narrow.
Utility model content
The purpose of this utility model is to provide a kind of cornish bit, the hole of vertical cyclindrical shape can only be entered with improving existing cornish bit
The problem of row processing.
What this utility model was realized in：
Based on above-mentioned purpose, this utility model provides a kind of cornish bit, including cutter and multiple connectors, multiple described
Connector is in turn connected to form connects chain, and connection is rotated between the adjacent connector, and the cutter includes connection end and use
In the cutting end of reaming, the connection end is connected with one end of the connects chain, and the connection end is located at the cutting end and institute
State between connects chain.
The cornish bit that this utility model is provided can be processed to common cylindrical hole, and the connects chain of cornish bit can
To bend, therefore, when in the face of bent hole, it is also possible to which is processed, so as to widen the use range of cornish bit so as to
More occasions can be adapted to.
Further, the connector includes ball-joint piece and bar shaped contiguous block, and described ball-joint piece is provided with the
One through hole, the first through hole are radially extended along described ball-joint piece, and described ball-joint piece by the first through hole
The bar shaped contiguous block is sheathed on, the adjacent bar shaped contiguous block rotates connection, the connection end and the bar shaped contiguous block
Connection.
When cornish bit device to hole is processed, ball-joint piece can be fitted with the inwall in hole, and such cornish bit is in work
When very can stablize, and mutually can rotate between the bar shaped contiguous block of Fructus Pruni woods, such cornish bit can just enter bending
Which is processed in hole.
Further, the described ball-joint piece centre position for being located at the bar shaped contiguous block length direction.
Bar shaped contiguous block is stablized by ball-joint piece to support, the ball-joint piece of centre for being located at bar shaped contiguous block
During position, the support force that bar shaped contiguous block two ends are subject to is identical, meanwhile, between the bar shaped contiguous block at ball-joint piece of two ends
Mutually can also constrain, at this moment bar shaped contiguous block is most stable.
Further, two the second through holes are provided with the bar shaped contiguous block, described ball-joint piece is located at two institutes
State between the second through hole, by cylinder pin connection, the straight pin is each passed through two to the adjacent bar shaped contiguous block simultaneously
Corresponding second through hole on the bar shaped connector, the axle of adjacent two bar shaped contiguous blocks along second through hole
Heart line direction relatively rotates.
Cylinder pin connection, its stable working state reliability are adopted between bar shaped connector.
Further, the axis parallel of two second through holes on the bar shaped contiguous block is arranged.
So connects chain only can be bent in one direction in bending, when being processed to bend pipe, also more square
Just.
Further, the connection end is rotated with the bar shaped connector by second through hole and is connected, the cutter
Direction of axis line along second through hole is rotated relative to the bar shaped contiguous block.
So cutter is more flexible, lighter during processing.
Further, two other the described bar shaped contiguous block positioned at the same bar shaped contiguous block two ends is located at institute respectively
State bar shaped contiguous block the same side.
So connects chain will not carry not big in the direction of the width, it is to avoid connects chain is occurred with the situation that hole wall is blocked.
Further, the two ends of the bar shaped contiguous block are respectively provided with fluted, and the groove is along the bar shaped connector
Centerline direction depression, the two ends of the groove extend respectively to two relative side walls of the bar shaped connector, described recessed
Third through-hole is respectively arranged with two side walls of groove, and two third through-holes are coaxial, the cornish bit also includes universal
Section, two adjacent bar shaped connectors are connected by the universal joint.
Bar shaped contiguous block is connected by universal joint, makes the bending direction of connects chain flexible and changeable, and applicable hole shape is more.
Further, the cornish bit also includes handle of a knife, the one end of the handle of a knife and the connects chain away from the cutter
Connection.
Handle of a knife can facilitate cornish bit and motor connection.
Further, the handle of a knife includes service portion and protection portion, and the service portion is fixedly connected with the protection portion, institute
State protection portion to be connected with the connector, the protection portion is located between the connector and the service portion, the protection portion
Cross-sectional area more than the protection portion cross-sectional area, and the cross-sectional area of the protection portion is transversal more than the connector
Area.
Protection portion can avoid cornish bit in the engineering of feeding, and the outfan of motor is contacted with mechanical part, so as to right
Mechanical part and motor all form good protection.
Compared with prior art, the beneficial effect of this utility model realization is：
The cornish bit that this utility model is provided can be processed to common cylindrical hole, and the connects chain of cornish bit can
To bend, therefore, when in the face of bent hole, it is also possible to which is processed, so as to widen the use range of cornish bit so as to
More occasions can be adapted to.
