Specific implementation mode
Embodiment：A kind of button collet, including mandrel 10, external member, button 8 and ball 2,10 one end of the mandrel be equipped with
The non-circular jack of screwdriver head form fit, 10 one end side wall of mandrel intersect the radial direction being connected to equipped with one with non-circular jack
Perforation, ball 2 can slide axially along the radial perforation and be positioned in the radial perforation, and ball 2 is not fallen out in non-circular
In jack, what external member can slide axially is sheathed on the outside of 10 one end of mandrel, and external member one end madial wall is equipped with one end internal diameter
Less than the step-like groove of other end internal diameter, the step-like groove just with the radial perforation position face of 10 one end of mandrel, button 8
It is fixedly installed on mandrel 10, button 8 can drive external member to slide axially along mandrel 10, in use, driving external member by button 8
It slides axially along mandrel 10, and then the step-like groove different inner diameters part for making one end and radial perforation face on mandrel 10,
When external member appears on the stage the small one end of scalariform groove internal diameter with radial perforation face on mandrel 10, step-like groove floor forces ball
2 stretch into it is stuck with the screwdriver head in it in the non-circular jack of 10 one end of mandrel, when external member appear on the stage scalariform groove internal diameter greatly one
On end and mandrel 10 when radial perforation face, space of the step-like groove floor between radial perforation on mandrel 10 increases, rolling
Pearl 2 can freely exit the non-circular jack of 10 one end of mandrel, and then thread off with screwdriver head of the non-circular jack in it, this hair
It is bright by a button 8 can fast driving external member slide axially, simple in structure, one hand can fast operating.
An annular groove is equipped on the inside of the external member other end, 10 outer sheath of mandrel is equipped with an elastomer 5,5 one end of elastomer
With 10 stationary positioned of mandrel, 5 other end elasticity of elastomer is tight against on annular groove other end side wall, elastomer 5 can be given in external member
The retentivity of one end that external member one keeps its step-like groove internal diameter small and radial perforation face on mandrel 10, avoids screwdriver head
It threads off in a state of use with ball 2, improves safety in utilization.
The external member includes housing 1 and inner sleeve 6, and the fixation of the inner sleeve 6 is inserted on the inside of 1 other end of housing, and inner sleeve 6 is arranged
In 10 outside of mandrel, 5 other end of elastomer is tight against 6 end surface of inner sleeve.
10 lateral wall of the mandrel is equipped with a protruding ring, and 5 one end of elastomer is closely against the protrusion ring surface.
Protruding ring on 10 lateral wall of the mandrel includes the first clamp spring 3 and the second clamp spring 4, on 10 lateral wall of the mandrel
It is formed with concave ring in one, 3 fixing card of the first clamp spring is set in the interior concave ring, and the second clamp spring 4 is closely sheathed on 10 lateral wall of mandrel
On, 4 one end of the second clamp spring is tight against 3 surface of the first clamp spring, and 5 one end of elastomer is tight against 4 surface of the second clamp spring, second clamp spring 4
Gap is less than 5 wall thickness of elastomer between external member madial wall, is realized by the first clamp spring 3 and is limited to the backstop of the second clamp spring 4, led to
It crosses the second clamp spring 4 and blocking limit is carried out to elastomer 5, the second clamp spring 4 improves barrier height, avoids elastomer 5 and crosses and leads
Cause failure.
The button 8 is spring leaf, and spring leaf one end is fixed positioned in mandrel tight against the external member other end, the spring leaf other end
On 10 lateral walls, chip architecture of the spring is simple, and operation is only need to press spring leaf with hand it is made to deform, in addition to spring leaf also may be used
Slide block type button 8 to be radial elastic sliding realizes axial cunning by inclined-plane with both sliding blocks in axial sliding tight against in a manner of
The sliding and then driving external member axial movement of block, can also be that axial dial type button 8 realizes the axially driving of external member.
10 lateral wall of the mandrel is equipped with one along its axially extending internal concave hopper chute, and spring leaf includes a bending section, should
Bending section both ends have each extended over a flat part, and what the flat part of spring leaf one end can slide is inserted in the internal concave hopper chute and set
In gap between part other end madial wall, the bending section of spring leaf tight against in external member the other end face, the spring leaf other end
Flat part is fixed in the internal concave hopper chute of mandrel 10, and the bending section by pressing spring leaf can be driven external member sliding, and spring
Piece and external member and 10 connection structure of mandrel are simple, convenient for assembling and repair.
The structure that the flat part of the spring leaf other end is fixed in the internal concave hopper chute of mandrel 10 is：10 outside of mandrel is tight
Close to be arranged with a resilient sleeve 9, the flat part of the spring leaf other end is located between resilient sleeve 9 and internal concave hopper chute bottom surface, using bullet
Property set 9 realize spring positionings it is simple in structure, convenient for assembly and disassembly repair, can also be in addition by rivet position.
The ball 2 is steel ball, and the radial perforation on 10 one end side wall of mandrel is in the opening of non-circular jack cross part
Diameter is less than the throat structure of ball 2, and throat structure inside most preferably with steel ball outer surface form fit, avoids that blocking occurs.
Be equipped with magnet 7 in the non-circular jack of 10 one end of the mandrel, 10 other end of mandrel be formed with for electronic work
Has the matched non-circular column tail portion of jack, magnet 7 is ejected when screwdriver head can be avoided to thread off, such as hexagonal tail, tetragonous tail
Deng convenient for being connect with electric tool.
