Into protrusion, the supported hole and support slot are coaxially disposed, and supported hole and support slot are respectively in upper backup pad and lower supporting plate
On be corresponding in turn to and set and be in rectangular distribution, the side of the upper backup pad length direction and lower supporting plate length direction
Side is connected by connecting plate, and the opposite side of upper backup pad length direction and the opposite side of lower supporting plate length direction are bent respectively
Clamp bar under clamp bar and bar shaped is formed in bar shaped, magnetic is also respectively connected in the upper clamp bar and lower side of the clamp bar away from connecting plate
Bar, the upper backup pad, lower supporting plate and connecting plate are bent to form for one piece of rectangular steel plates.
Chalk is penetrated in supported hole, and chalk end is placed in support slot, you can fixed chalk, afterwards can will be upper
Clamp bar and lower clamp bar, which coordinate to be engaged by clamping with the chalk front of the slot of blackboard bottom, to be fixed, and can also be adsorbed by magnetic stripe and blackboard solid
It is fixed, or, therefore this chalk bearing adapts to the needs that different occasions place chalk. directly using raised support on the table.
In a kind of above-mentioned multifunctional chalk bearing, the upper backup pad bottom surface is equipped with court with supported hole correspondence position
The annular guide ring set to support slot.
Guide ring is set conveniently to place chalk.
In a kind of above-mentioned multifunctional chalk bearing, the lower supporting plate is respectively close to the side of connecting plate and close
The side of lower clamp bar is bent to form two bar supporting feets being parallel to each other towards lower supporting plate bottom respectively.
Therefore it is more convenient to place on the table.
In a kind of above-mentioned multifunctional chalk bearing, the support slot is inversed taper platform shape structure, and support slot notch
More than support slot slot bottom.
Therefore it is adapted to the chalk of different size.
In a kind of above-mentioned multifunctional chalk bearing, the support slot slot bottom is equipped with beam.
Avoid producing noise in the moment for being put into chalk.
In a kind of above-mentioned multifunctional chalk bearing, four branch are respectively equipped with the upper backup pad and lower supporting plate
Support hole and four support slots.
Compared with prior art, the invention has the advantages that：
Chalk is penetrated in supported hole, and chalk end is placed in support slot, you can fixed chalk, afterwards can will be upper
Clamp bar and lower clamp bar, which coordinate to be engaged by clamping with the chalk front of the slot of blackboard bottom, to be fixed, and can also be adsorbed by magnetic stripe and blackboard solid
It is fixed, or, therefore this chalk bearing adapts to the needs that different occasions place chalk. directly using raised support on the table.

Embodiment
It is the specific embodiment of the present invention and with reference to attached drawing below, technical scheme is further described,
But the present invention is not limited to these embodiments.
As shown in Figs 1-4, a kind of multifunctional chalk bearing of the present invention, including main body, main body include arranged in parallel
Circular support hole 11 and support slot 21 are respectively equipped with upper backup pad 1 and lower supporting plate 2, upper backup pad 1 and lower supporting plate 2, and
Support slot 21 is stamped and formed out for lower supporting plate 2, and protrusion 22 is formed in 2 bottom of lower supporting plate, and supported hole 11 and support slot 21 are same
Axis is set, and supported hole 11 and support slot 21 are corresponding in turn on upper backup pad 1 and lower supporting plate 2 set and in rectangular respectively
Distribution, the side of 2 length direction of side and lower supporting plate of 1 length direction of upper backup pad are connected by connecting plate 3, upper backup pad
The opposite side of 2 length direction of opposite side and lower supporting plate of 1 length direction is bent to form in bar shaped under clamp bar 13 and bar shaped respectively
