A neck is done, prolonging the second Access Division inward flange same direction close to stacker side in several necks is extended with several cards
Block groove, several fixture block grooves are used for clamping several fixture blocks, set in several fixture block grooves close to second Access Division outer face one end
There are several card article grooves, several card article grooves are for several card articles of clamping；Several fixture blocks correspond with several necks,
Several fixture blocks are inserted and are screwed into several fixture block grooves by several necks, and several card articles are stuck in several card article grooves,
First Access Division of cover body is removably connected with the second Access Division of stacker.
In the utility model, it is preferred that the quantity of several fixture blocks and several necks is three.
In the utility model, it is preferred that the shape of cross section all same of several card articles and several card article grooves.
In the utility model, it is preferred that the shape of cross section of several card articles and several card article grooves is semiellipse
Shape.
The beneficial effects of the utility model are：Attachment structure of the present utility model is clamping, during installation, several fixture blocks with
Several necks are corresponded, and several fixture blocks are inserted and are screwed into several fixture block grooves by several necks, several card articles
It is stuck in several card article grooves, now, the first Access Division of cover body is connected with the second Access Division of stacker；, will during dismounting
Several card articles opposite direction from several card article grooves is rotated in several necks, and several fixture blocks divide from several necks
Separate out and, so as to which the second Access Division of the first Access Division of cover body and stacker be dismantled.Connection knot of the present utility model
Structure is simple compared to screw thread rotation attachment structure, installation, convenient disassembly, that is, inserts, rotates and can connect, reversely rotate, separate
I.e. detachable, the anglec of rotation is small；In addition, attachment structure stability of the present utility model is good, will not connect because of external environment influence
The stability connect.
