The utility model patent that Chinese patent publication number CN2830108, the applying date be on July 29th, 2005, be entitled as " windshield wiper type blackboard " discloses a kind of windshield wiper type blackboard that is made of the car windscreen Wiper system, the wiper of this Wiper system is made up of swing arm and rub body material, and the rub body material is fixed on the swing arm; The swing arm end is connected on the transmission control device, and transmission control device is installed on the wall in the blackboard outside.Though this patent is simple in structure, without manually-operated, because there is the dead angle in the rain brush motion, during therefore actual the use, on blackboard the defective that the subregion can not be clipped all the time will appear.
The utility model patent that the open CN2806184 of China Patent No., the applying date be on July 4th, 2005, be entitled as " windshield wiper type blackboard " relates to a kind of windshield wiper type blackboard eraser, comprise rectangle blackboard and the cleaning brush holder support that has cleaning cloth, the top of cleaning brush holder support is fixed on point midway place, the long limit of blackboard by rotating shaft, and the brush holder support other end and connecting rod flexibly connect; On the cleaning brush holder support hook is installed.Also there is the problem that is difficult to the whole blackboard of disposable removing zone in this patent, and reset procedure is slower when using.
Summary of the invention
The purpose of this invention is to provide a kind of omnibearing fast blackboard eraser, it is simple in structure, low cost of manufacture, easy for operation, in the time of can solving existing blackboard eraser effectively and remove blackboard dust overweight, be difficult to remove whole blackboard zone and the unhappy problem of removing speed.
The object of the present invention is achieved like this: a kind of omnibearing fast blackboard eraser comprises: power set, and it is installed in the outside of blackboard; One carriage release lever, it is strip and is connected with described power set, can select a ground and carry out laterally or vertically move in this blackboard, is fixed with sassafras body material on it.
Preferably, described power set are an electric device.
Preferably, be provided with a switch on the described electric device at least, be used to control described carriage release lever in blackboard laterally or vertically move, and described sassafras body material is rubbed mutually with the plate face of blackboard.
Preferably, also comprise a remote controller, described electric device is provided with a remote-control-signal reception unit that is complementary with this remote controller, at least be provided with a switch on the described remote controller, be used to control described carriage release lever in blackboard laterally or vertically move, and described sassafras body material is rubbed mutually with the plate face of blackboard.
Preferably, described power set also comprise one with the parallel hand gear that is connected in described carriage release lever of described electric device.
Preferably, described power set be one manually the device.
Preferably, described sassafras body material is felt, sponge or flannelette.
The present invention is owing to adopted above technical scheme, make it compared with prior art, have the following advantages and good effect: simple in structure, the low cost of manufacture, easy for operation of this omnibearing fast blackboard eraser, pick-up performance is good, and plate face cleannes are good, can effectively control the pollution of dust to environment, ensure teachers and students' health, therefore wiping of the material that is applicable to all kinds of schools, the enterprises and institutions various blackboards plane that to be metal, glass, cement or wood etc. write with chalk possess good promotion and application and be worth.

The specific embodiment
Embodiment 1
As shown in Figure 1, it is a preferred embodiment of omnibearing fast blackboard eraser of the present invention.It comprises: an electric device 1, and it is fixedly mounted on the outside body of wall of blackboard 4; A carriage release lever 2 that is strip, it is connected with power set 1, and the control that is subjected to this electric device 1 can be carried out laterally moving in blackboard 4, on the contact-making surface of this carriage release lever 2 and blackboard 4 sassafras body material 3 (felt, sponge or flannelette) is housed simultaneously.At least be provided with a switch (not shown) on electric device 1, when this switch of direct unlatching, carriage release lever 2 promptly laterally moves back and forth in blackboard 4 fast, the sassafras body material 3 and the plate face of blackboard 4 is rubbed mutually go up the content that chalk is put down in writing to remove clean its.
Control for more convenient, omnibearing fast blackboard eraser of the present invention has also designed a remote controller (not shown), and a remote-control-signal reception unit (not shown) that is complementary with this remote controller is housed on this electric device 1.When removing blackboard, the user can appropriateness away from blackboard, realize so more helping the process of above-mentioned removing blackboard protecting the health by the switch on the remote controller away from dust.
Embodiment 2
For avoiding because of power failure, electric device failure and other reasons, the operational failure of omnibearing fast blackboard eraser of the present invention.Therefore, as shown in Figure 2, the power set 1 in the present embodiment omnibearing fast blackboard eraser also further comprise a hand gear, and it and electric device walk abreast and be connected in carriage release lever 2, can realize the motion control to this carriage release lever 2 equally.In addition, consider, need remove fast blackboard in some cases, thus this carriage release lever 2 is arranged to and can be vertically moved in blackboard 4, to raise the efficiency, to save the time of wiping.
