Problems solved by technology
[0003] The above-mentioned locking device 10 can indeed achieve a locking effect on the eye protection cover 3, but there is still room for improvement in use. Usually, a handle unit (not shown) is connected to the side of the saw arm unit 1 to provide operation. The operator holds it with his hand, thereby operating the saw arm unit 1 to perform downward sawing action. The handle unit should be as close as possible to the position of the locking device 10, so that the operator’s hand can hold the handle unit and at the same time Operate the handle 13 that is pressed to the locking device 10. Since the locking device 10 must be located adjacent to the saw arm unit 1, the installation height of the handle unit is indirectly limited. The handle unit is at a lower position. However, if the handle unit is raised in order to meet the operating height of the human body, the operator’s hand cannot reach the handle when holding the handle unit. To the handle 13 of the locking device 10, it will cause great trouble in operation

The electromagnetic locking setting device to cut eye protection cover comprises a saw arm unit, a handle unit and a eye protection cover, which is characterized in that it has a block unit with a prop member joint of a prop end and connect end on side of saw arm unit, and a electromagnetic unit with a drive rod to link with connect end. The operator can press a button to control electromagnetic unit and separate the member and cover conveniently.
Description
【Technical field】 [0001] The invention relates to a cutting machine, in particular to an electromagnetic locking device for the eye protection cover of the cutting machine which uses electromagnetic control to open and close the eye protection cover. 【Background technique】 [0002] see figure 1 As shown, the general cutting machine mainly has a saw arm unit 1, a circular saw blade 2 with a shaft arranged inside the saw arm unit 1, and a set of eye protection set on the saw arm unit 1 to cover the circular saw blade. Cover 3, the saw arm unit 1 is provided with a linkage rod group (not shown) on the side to connect with the eye protection cover 3, when the saw arm unit 1 is pressed down, the eye protection cover 3 is connected by the linkage rod group It can be turned and opened by driving, so that the circular saw blade 2 is exposed for sawing work. In order to prevent the saw arm unit 1 from exposing the circular saw blade 2 due to mispressing and causing danger, usually o...
