For achieving the above object, the utility model provides following technological scheme:

A kind of structure improved vacuum chuck, comprise shell, undersetting and the sucker of box-like, described undersetting in the form of a ring, on it, there are multiple plunger holes, on undersetting edge circumference, there is more than two slideway with slope, there is through hole at described shell center, has the boss corresponding with the slideway quantity of undersetting on outer casing inner wall circumference, and each boss directly contacts with each slideway on undersetting respectively; Described sucker periphery has multiple plungers, plunger embeds the plunger hole of undersetting, there is an attachment post at sucker center, the middle part of described attachment post is provided with snap ring, the peritreme of described through hole inwardly forms several holds the barb pawl of described attachment post tightly, and the claw of barb pawl is against on the attachment post wall of snap ring downside.

Preferably, the upside of described snap ring forms the frustum face that barb pawl opens of being convenient to.

Preferably, on described slideway, there is positioning ditch.

Preferably, the top of described attachment post is provided with central blind hole, and the bottom of hook platform forms the locating stud of pegging graft with described central blind hole, locating stud and central blind hole interference fit, and the middle part of locating stud is provided with air outlet hole, on hook platform, is provided with hook.

Preferably, described air outlet hole is tapered, and its upper end is communicated to the hook mounting groove in hook platform.

Preferably, on described hook platform, be plugged with end cap, hook platform and end cap coordinate the described hook mounting groove of formation.

Preferably, a side of described sucker forms the flange of being convenient to sucker to tear.

Preferably, be provided with inside and outside two groups of ring rails that formed by described slideway on described undersetting, described boss correspondence is provided with two groups; Slideway on described interior ring rail and the slideway on the outer shroud rail several angle that staggers mutually.

The utility model compared to existing technology outstanding and useful technique effect is:

Between shell of the present utility model and attachment post, coordinate by equal barb pawl and snap ring, without the another jump ring that adds, and assembling is simple, only attachment post need be inserted in the through hole at shell middle part, and the application of force is flared to by snap ring barb pawl can to complete assembling; The upside of snap ring forms is convenient to the frustum face that barb pawl opens, and makes assembling more laborsaving; Attachment post and hook platform are by locating stud and central blind hole interference fit, and it coordinates simple, in the time that both plug-in mountings are complete, if with glue shutoff air outlet hole, the assembling that can further stablize both; Hook platform and end cap coordinate and form hook mounting groove, and this design makes hook can directly insert hook mounting groove, then prevent that by end cap it from deviating from; The flange of sucker one side is convenient to directly sucker be torn; Slideway on slideway and outer shroud rail on the interior ring rail several angle that staggers mutually, it can effectively improve the fitment stability between shell and undersetting.
