Sleeve is in the big width slot in the bottom of convex shape groove and is pressed against on covering plate, and the top that demarcation strip stretches out convex shape groove is little
Width slot, the rear wall of demarcation strip is fixed with adsorption bar, adsorption bar be pressed against correspondence permanent magnetism iron bar on and with permanent magnetism iron bar phase
Absorption.
The bottom surface, middle part of described convex shape groove has low groove, and the lower end of buffer spring is in low groove and is fixed on
On the bottom surface of low groove.
Described location shrinkage pool is bolted with positioning sleeve, the medial wall of positioning sleeve has multiple spacing screw, spacing screw
In be bolted with spacing ball headpin plug, holding post sleeve is in corresponding positioning sleeve, and the steel ball of spacing ball headpin plug is nested in holding
In the shrinkage pool having on the lateral wall of post.
Having bottom recess on the bottom surface of described positioning sleeve, spring sleeve is in bottom recess, and the lower end of spring is fixed on
On the bottom surface of bottom recess, permanent magnet block is put forth effort in the upper end of spring, and permanent magnet block adsorbs on the bottom face of holding post.
The left and right sides of described gripper shoe has a ladder hole, and what ladder hole and the rear wall of support side plate had determines
Hole, position is corresponding, and the head sleeve of location bar is in the major diameter shoulder hole section of ladder hole, and the bar portion sleeve of location bar is on rank
The small diameter bore section of ladder through hole neutralizes in hole, location.
Being bolted with bulb plunger in the connecting screw hole having on the medial wall in hole, described location, location bar is in hole, location
Having multiple fixing shrinkage pool on lateral wall, bar portion, the steel ball of bulb plunger is nested in the fixing shrinkage pool of correspondence.
The beneficial effects of the present invention is:
It can be simply mounted on the platen of dais, thus conveniently books etc. are carried out classification and put, thus it is whole to improve it
Qi Du, meanwhile, all parts can be dismantled, and facilitates dais to carry.

Detailed description of the invention:
Embodiment: as shown in Fig. 1 to Fig. 7, a kind of dais with detachable Book-rest, including dais platen 100, institute
The bottom surface, two ends, left and right stating dais platen 100 is fixed with multiple inserting column 109, and the end face of two support side plate 20 in left and right has many
Individual location bolt apertures 21, permanent magnet swivel nut 22 is screwed onto in the location bolt apertures 21 of correspondence, on the medial wall of permanent magnet swivel nut 22
Forming spline groove, the bottom of inserting column 109 is spline shaft, and spline shaft sleeve also adsorbs in permanent magnet swivel nut 22,
The outer wall splined projections sleeve of spline shaft is in corresponding spline groove, and the bottom face of spline shaft is pressed against permanent magnet swivel nut
On the bottom surface of 22, the two ends of the front face of gripper shoe 30 are pressed against on the rear wall of two support side plate 20, and gripper shoe 30 is fixed
In two support side plate 20, gripper shoe 30 and two support side plate 20 are pressed against on the ground;
The end face of dais platen 100 has multiple location shrinkage pool 101, and Book-rest base plate 10 is pressed against dais platen 100
On end face, the bottom surface of Book-rest base plate 10 has multiple holding post 11, and holding post 11 is arranged in the shrinkage pool 101 of location;
The both sides of Book-rest base plate 10 are fixed with side shield 12, and the rear end of Book-rest base plate 10 is fixed with backboard 13;
The end face of the Book-rest base plate 10 between two side shields 12 forms multiple convex shape groove 14, convex shape groove
There is at the backboard 13 of 14 correspondences vertical limited impression 15, nested and be fixed with permanent magnetism iron bar 16 in vertical limited impression 15,
