Description
Technical field
The utility model relates to a kind of drill bit, is specifically related to a kind of novel telescopic type drill bit.
Background technology
In the use procedure of drill bit, often can run into the long or too short situation of drill bit, the scope of application of drill bit is made to be subject to larger restriction under these circumstances, have impact on the further use of drill bit, reduce the result of use of drill bit, part drill bit is also had often to locate when location inaccurate, easy formation position error, the drilling effect of the workpiece processed is made not to be fine, the centre-to-centre spacing of boring controls not accurate, the processing effect of workpiece can not be ensured, drill bit rocks larger when in use, also the drilling effect of workpiece can be affected, do not ensure the precision of processing.
Summary of the invention
The purpose of this utility model is to provide a kind of self-align standard, rocks little a kind of novel telescopic type drill bit.
The technical solution of the utility model is: a kind of novel telescopic type drill bit, comprise drill bit, connection handle is provided with after described drill bit, described connection handle is triangle joint handle, described connection handle is provided with extensible member, described extensible member is superposing type sleeve, described superposing type sleeve is made up of two layers of sleeve, described connection handle peripheral hardware ground floor sleeve, outer surface sleeve is provided with outside described ground floor sleeve, be matched in clearance between described outer surface sleeve and ground floor sleeve, described outer surface sleeve is provided with connection fixture, described connection fixture is connecting groove.
Described drill bit both sides are provided with fixture, described fixture is fixing support rack, and described fixing support rack is demountable structure, is connected bottom described fixing support rack with connection handle, described fixing support rack is provided with adsorption piece, and described adsorption piece is flexible sucker.
Described drill bit is provided with cutting edge, described cutting edge is mutual chi structure, and described cutting edge is provided with keeper, and described keeper is location thimble, described location thimble is stretching structure, and described location thimble is positioned at the place that two cutting edges intersect.
The utility model has the advantages that: on connection handle, be provided with extensible member, conveniently can control the distance of stretch out and draw back of drill bit, the scope of application of the drill bit expanded, make drill bit arbitrarily can control length, facilitate the Drilling operation of parts, fixture is provided with in drill bit both sides, drill bit can be allowed to carry out self-align, prevent drill bit from rocking on both sides when processing, have impact on the crudy of workpiece, be provided with keeper on the cutting edge, the location of drill bit can be facilitated, timely controlled working error, ensures that boring is on a center line, ensure that the machining accuracy of workpiece.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 is drill bit, 2 is connection handle, and 3 is ground floor sleeve, and 4 is outer surface sleeve, and 5 is connection fixture, and 6 is fixture, and 7 is adsorption piece, and 8 is cutting edge, and 9 is keeper.
