Easily enter aluminium skimmings for existing extension bar link position in background technology, the problem of causing extension bar stuck or damage, this reality
It is to provide a kind of in the case where ensureing extension bar function with new purpose, can prevents aluminium skimmings from entering, while can also save
The anti-floating screw tap of cost enters the connection rod structure of bits.
In order to achieve the above object, the anti-floating screw tap of the utility model design enters the connection rod structure of bits, it is characterised in that
Including extension bar body, described extension bar body one end is with stretching into screw-tap head restraint, and the other end is connected with tap chuck；The extension bar sheet
One end that body is stretched into screw-tap head restraint is provided with circumferential annular groove, and is flexibly connected by above-mentioned annular groove with screw-tap head restraint,
The other end of the extension bar body is provided with axial blind hole, and the blind hole hole wall is provided with multiple top wire holes with ft connection, top
Silk fixes the tap chuck for stretching into the blind hole through the top wire hole.
It is preferred that, the extension bar body is two sections of ladder shaft-like parts, and the small one end end of the diameter of axle is recessed provided with the annular
Groove, the big one end end of the diameter of axle is provided with the blind hole.
It is further preferred that the big section of the extension bar body diameter of axle is provided with first boss close to the end face of the small section of axle journal,
Screw-tap head restraint is provided with the first groove coordinated with the first boss.
It is further preferred that end face of the big section of the extension bar body diameter of axle away from the small section of the diameter of axle is provided with the second groove,
Tap chuck is provided with the second boss coordinated with second groove.
It is preferred that, multiple top wire holes are disposed radially.
It is further preferred that multiple top wire holes are located at same axial normal plane.
It is further preferred that one end that the jackscrew can be contacted with tap chuck is sphere.
The beneficial effects of the utility model are：Extension bar of the present utility model reduces each connection by way of jackscrew is fixed
Flying height between part, being effectively prevented aluminium skimmings, to enter the extension bar that causes stuck or damage the generation of problem, simple in construction, test
Demonstrate,prove reliable and stable, manufacturing cost low.
Brief description of the drawings
Fig. 1 is assembling structure schematic diagram of the present utility model
Fig. 2 is structural representation of the present utility model
In figure：Extension bar body 1 (annular groove 1.1, blind hole 1.2, top wire hole 1.3, first boss 1.4, the second groove
