when the adjustable clamp is used, the inclination angle of the drawing board (10) needs to be adjusted according to the drawing habit of a user, so that the user can draw at the front end of the drawing board (10) conveniently, when the inclination angle of the drawing board (10) is adjusted, the support rod (7) is rotated on the inner side of the first fixed frame (5) by rotating the support rod (7) with the first rotating shaft (6) as the shaft, so that the purpose of adjusting the angle of the support rod (7) is achieved, then the clamp rod (83) is rotated on the inner side of the second fixed frame (81) with the second rotating shaft (82) as the shaft, so that the lower end of the clamp rod (83) is clamped at the front end of the limit block (85) inside the sliding rail (84), the support rod (7) can be supported and fixed by the clamp rod (83), the adjustment mode is more flexible, the user can experience in drawing by adjusting the angle of the drawing board (10) through adjusting the angle of the drawing board (10), when the larger drawing board (10) needs to be replaced, the limit block (113) is pulled upwards, so that the movable rod (112) is on the inner side of the fixed block (111), the movable rod (112) can be moved upwards by the movable rod (112), the movable rod (116), and then the clamp rod (114) can be moved upwards, the clamp plate can be moved upwards by the movable rod (114), and the movable rod (116) can be locked on the movable rod (116), thereby achieving the purpose of fixing the upper clamping plate (116), then placing a bigger drawing board (10) at the lower side of the upper clamping plate (116) at the upper end of the lower bracket (9), at the moment, screwing the locking knob (114) to loosen the movable rod (112) and the fixed block (111), the spring (115) restores to the original state under the action of the elasticity thereof to push the upper clamping plate (116) and the movable rod (112) to move downwards, the drawing board (10) can be clamped between the upper clamping plate (116) and the lower bracket (9) through the downward movement of the upper clamping plate (116), the drawing boards (10) with different sizes can be replaced according to the actual requirements, the drawing board is more flexible and has wider application range, and finally, when the prior storage device stores tools, the drawing tools are exposed outside, when the storage mechanism (13) is used, the drawer hopper (132) is driven to slide out of the inner side of the storage basket (131) by pulling the handle (134), then drawing tools are placed on the inner side of the drawer hopper (132), the drawing tools can be stored, meanwhile, the drawing tools in the drawer hopper (132) can be prevented from being damaged due to the fact that rainwater is poured into the drawer hopper (132) in rainy days, the drawing tools can be protected and stored, in addition, the lower end of the clamping rod (83) is taken out from the sliding rail (84), then the clamping rod (83) rotates by taking the second rotating shaft (82) as a shaft, and therefore the clamping rod (83) is rotated to be close to the supporting rod (7), use first axis of rotation (6) to rotate as the axle with bracing piece (7) again, thereby reach the purpose of closing up between bracing piece (7) and base (1), thereby reach the purpose of folding the accomodating with the device, because drawing board (10) conveniently take off in the inboard of fixture (11), take off drawing board (10) again and place between first mount (5) and second mount (81), thereby reach and accomodate fixture (11) between bracing piece (7) and base (1), can make things convenient for the folding of whole device to accomodate, the convenience is the carrying of whole device when outdoor drawing.
