Because there is the air film of approximate sealing in Socket walls portion when the instrument of insertion, behind the insertion instrument, air in the air film slowly releases, be subjected to Negative Pressure Difference when making puller and produce extracting difficulty, and the soft material resilience of Socket walls wraps tightly pad, the stiction super large that pad the is subjected to instrument that more makes is extracted difficulty, therefore be provided with rib at the jack inwall, utilize the rib liner between pad and Socket walls, Socket walls portion still can be kept behind the insertion instrument and extraneous air communication, make insertion or puller smooth; The gross area that rib contacts with pad is less, frictional force is little, rib and cooperating of pad can be established tightly slightly, the defective that both can avoid the jack instrument bigger than normal of prior art easily to get loose, can reach firmly not too big effect of insertion or puller again, can also compensate because the variation of the fit dimension that jack uses rib to wear and tear for a long time to be caused; Owing to be provided with rib, the most important thing is to overcome conventional understanding mistaken ideas, avoided the soft material resilience of Socket walls to wrap tightly the phenomenon generation that pad makes that stiction super large instrument is difficult to extract.

Described holder can be made of some cylinders disjunctor arranged side by side, and cylinder is provided with jack; Holder also can be some jacks to be set to constitute on cuboid.The pad diameter that places as required in the aperture of jack is different and be provided with respectively.

Described housing, it can be the cuboid of an opening, enclosure interior is divided into two-stage structure, its epimere is the cavity of described opening of ining succession, holder can be placed in this cavity, its hypomere is provided with the hierarchic structure as collet, after instrument is inserted through jack, tool end withstands on hierarchic structure and is located, the height of ladders at different levels and the corresponding setting in the jack aperture on the holder, particularly, the little corresponding ladder height in jack aperture is big, and the big corresponding ladder height in jack aperture is low, and so correspondence setting can make the instrument of different size insert its head exposes behind the holder length near equating, make put neat, and make the instrument of thin weak point can have certain length expose and slightly long instrument unlikely expose oversize; Holder can be fixedly connected with being pressed into being connected of housing, or with glued joint connecting, and the edge that perhaps utilizes the opening part of housing to be provided with inside turnover blocks holder; The two ends of housing are provided with the pivot that is used for the instrument cases pivot joint; Instrument cases preferably adopt to have bigger flexible engineering plastics and makes, and is good with transparent engineering plastics.

The present invention has following beneficial effect compared with the prior art:

1. in Socket walls rib is set, eliminates the air negative pressure zone of Socket walls portion sealing, instrument is extracted easily;

2. Socket walls is provided with rib, the contact area of minimizing instrument and Socket walls, reduce frictional force, the tightness that rib contacts with tool shank can be established tightly slightly, make firm can not being difficult to again of tool holding insert or extract, especially avoided the soft material resilience of Socket walls to wrap tightly the phenomenon generation that pad makes that stiction super large instrument is difficult to extract;

3. because the active force of plug-pull tool greatly reduces, make particularly stressed the reducing of pivot on the housing of correlated parts, can prolong the service life of pivot and entire tool box.
