One-to-one protrusion 211, four groups of protrusions 211 circumferentially array distribution, peripheral surface and the cam segment 21 of protrusion 211
Spacing between center line becomes larger, and abutting against inner end that bar 23 is located in housing 22 can be with the peripheral surface of corresponding cam segment 21
Against abutting against the outer end of bar 23 can abut against with square tube 4.
The inner end for abutting against bar 23 is bolted with against nut 24, is equipped with against between nut 24 and housing 22 so that abutting against bar
23 inner end always with the peripheral surface of corresponding cam segment 21 against spring 25.The structure can so that abut against bar 23 retracts automatically
It is resetted in housing 22.Abut against bar 23 outer end be bolted in abut against block 27, inside abut against the outside tool of block 27 there are two being mutually perpendicular to
Abut against face.Maximum intensity at the interior angle of square tube 4, it is interior in positioning to abut against that block 27 is opposite with the interior angle of square tube 4 to be abutted against, it can be calmly
When position using larger pretightning force and increase with the contact area of square tube 4, so as to increase the frictional force with square tube 4, in promotion
The bonding strength of mandrel and square tube 4.The inside of housing 22 is fixed with four and four groups of 211 one-to-one bars 28 of protrusion,
In the distance for abutting against the stretching housing 22 of bar 23, most bar 28 can be abutted against with protrusion 211 in short-term.Bar 28 can limit rotation axis
Rotational angle so that abut against bar 23 without departing from corresponding protrusion 211.
Housing 22 is stretched into square tube 4 when positioning square tube 4, bar 23 is abutted against at this time and stretches into square tube 4, by driving electricity
Machine 26 rotates rotation axis, and with the rotation of cam segment 21, protrusion 211 can will abut against bar 23 and be released to the outside of housing 22, and four
Group abuts against bar 23 and synchronizes protruding, and when the outer end for abutting against bar 23 acts against on the inner wall of square tube 4, inner spindle and square tube 4 are fixed
Position；It can be adapted to different size of square tube 4 by the inner spindle of above structure so that the applicability of inner spindle is wider, to save
Testing cost.
This outer collet 3 is respectively positioned on including the chuck 31 and four pieces of gripping blocks 32, four pieces of gripping blocks 32 that can be sleeved on 4 outside of square tube
On the inside of chuck 31, it is respectively and fixedly provided with guide rod 33 in every piece of gripping block 32, guide rod 33 is plugged on chuck 31, four guide rods 33
Center line intersection be also bolted with gripping block 32 on the center of chuck 31, chuck 31 and abut against bolt 34 correspondingly, abut against
The end of bolt 34 can act against gripping block 32 so that four pieces of gripping blocks 32 clamp square tube 4.
Four pieces of gripping blocks 32 circumferentially array be uniformly distributed and every piece of gripping block 32 respectively with four exterior angles pair of square tube 4
Together, the side at gripping block 32 towards 4 exterior angle of square tube offers right angle groove 341, and the cell wall of stabilizer blade groove can be with the outer wall of square tube 4
It reclines.Gripping block 32 can be made to act against at the exterior angle of square tube 4 with this configuration, each gripping block 32 acts against square tube 4
On two sides, therefore the stability for clamping square tube 4 can be increased.It is provided with skid resistance strip on the two sides cell wall of right angle groove 341,
Skid resistance strip direction on the two sides cell wall of right angle groove 341 is mutually perpendicular to.It can increase folder by orthogonal skid resistance strip
The tightly frictional force between block 32 and square tube 4 promotes the firmness that gripping block 32 clamps square tube 4.Each gripping block 32 corresponding two
Root abuts against bolt 34, and two abut against the both sides that bolt 34 is located at guide rod 33, and two abut against bolt 34 and are mutually perpendicular to.Chuck
31 section is square, and four corners of chuck 31 are provided with chamfering 311, and four pieces of gripping blocks 32 and four chamferings 311 1 are a pair of
It answers, guide rod 33 is plugged at chamfering 311.
