Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of blackboard-cleaning device easy to use, packet Fixing seat 1, limit base 2 and support base 3 are included, 1 one middle side part of fixing seat offers groove 11, passes through inside the groove 11 Bolt is fixedly connected with supporting block 12, and 12 side of supporting block is adhesive with cotton sheath 13 by velcro, facilitate user into Also user is facilitated to clean while row dismounting and change, 1 upper surface of fixing seat and lower surface are welded with limit base 2, It is socketed with magnet block 21 inside the limit base 2, effectively this blackboard-cleaning device is adsorbed with blackboard, and then conveniently User also improves the efficiency for finding this blackboard-cleaning device, 1 other side of the fixing seat middle part while capable of taking in time It has been bolted to connection support base 3, through-hole 31 is offered in the middle part of the support base 3, is socketed with branch inside the through-hole 31 Fagging 32,32 both ends of support plate are welded with magnet block 21 respectively, and 32 side of support plate is welded with two springs 35, institute It states 35 one end of spring and 31 inner wall of through-hole welds, 32 other side of support plate is welded with pressing plate 33, user is facilitated to pass through pressing Pressing plate 33 is shunk two magnet blocks 21 by support plate 32, and then user is facilitated to wipe blackboard.

Plastic foam 14 is filled with inside the cotton sheath 13, the plastic foam 14 is in rectangle, effectively plays branch The effect of support, while facilitating support cotton sheath 13 and blackboard being wiped by cotton sheath 13, the cotton sheath 13 One middle side part offers dimpled grain, improves wiping efficiency, and 21 side of magnet block and 13 side of cotton sheath are in same plane On, this blackboard-cleaning device is effectively adsorbed on blackboard, the support base 3 is U-shaped, and the through-hole 31 is U-shaped, The support plate 32 is U-shaped, is easy to use, and 33 side of pressing plate is adhesive with protective pad 34 through support base 3, effective to improve The pressing experience of user when in use, effectively plays the role of protecting finger.
