Bolt is fixed with the sleeve for being sleeved on outside support rod on the lower end surface of drawing board, is threadedly coupled on the side wall of sleeve useful
In the hand-tighten bolts of locking sleeve and support rod.
The multifunctional mathmatical draft holder of the utility model, wherein the outer cover of the support rod below sliding sleeve is equipped with bullet
Spring；By the setting of spring, after the hand-tighten bolts on sliding sleeve are unscrewed, sliding sleeve can move up under the action of the spring,
So, supporting mechanism can collapse automatically.
The multifunctional mathmatical draft holder of the utility model, wherein be fitted with non-slip mat on the lower end surface of second connecting rod；Pass through
The setting of non-slip mat, the frictional force being capable of increasing between second connecting rod and ground so can play anti-skidding effect.
The multifunctional mathmatical draft holder of the utility model, wherein if being provided with arterial highway non-slip groove on the lower end surface of non-slip mat；
By the setting of non-slip groove, the frictional force between non-slip mat and ground can be further increased, so, can be further served as
To anti-skidding effect.
The multifunctional mathmatical draft holder of the utility model, wherein a pair is provided at the outer end of hand-tighten bolts can be with hand
The end of finger offsets to facilitate the lug of rotation hand-tighten bolts；By the setting of lug, can be brought to the rotation of hand-tighten bolts
It is convenient.
After the utility model is by using above structure, internal drawing board can be disassembled easily, and in cunning
After hand-tighten bolts are unscrewed on set, supporting mechanism is able to carry out folding, so, can when storing mathematics draft holder
Reduce the occupied space of mathematics draft holder.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model；
Fig. 2 is amplified structural schematic diagram at A in Fig. 1.
Specific embodiment
Specific embodiment of the present invention is described in further detail with reference to the accompanying drawing.
In the description of the present invention, unless otherwise indicated, term " on ", "lower", "left", "right", "front", "rear",
The orientation or state relation of the instructions such as " top ", " bottom " are orientation based on the figure or state relation, merely to just
In description the utility model and simplify description, rather than the certain party that the mechanism of indication or suggestion meaning or component must have
Position is constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " connection "
It shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can be direct phase
It even, can also be indirectly connected through an intermediary.For the ordinary skill in the art, on being understood with concrete condition
State the concrete meaning of term in the present invention.
A kind of multifunctional mathmatical draft holder, including support rod 1, the upper end of support rod 1 are detachably connected with drawing board 2,
The outside of support rod 1 is slideably set with sliding sleeve 3, and the lower end surface of sliding sleeve 3 is by four in circumferential equally distributed support machine
Structure is connect with the lateral wall of 1 lower end of support rod, and each supporting mechanism includes first connecting rod 41 and second connecting rod 42, first connecting rod
41 one end and the lower end surface of sliding sleeve 3 are hinged, and one end of the other end and second connecting rod 42 of first connecting rod 41 is hinged, second connecting rod
42 other end and the lateral wall of 1 lower end of support rod are hinged, are threaded on the side wall of sliding sleeve 3 for locking sliding sleeve 3 and branch
The hand-tighten bolts 5 of strut 1 are fixed with the sleeve 21 for being sleeved on outside support rod 1, sleeve 21 on the lower end surface of drawing board 2
