During this operation, the workpiece 4 is wrapped in the cover 1, and in this state, the palm portion 2 and the sector portion 3 of the cover 1 are freely bent inward by two fingers 7, 8. be able to. Due to this curvature, depending on the scattering state of the fine powdery substance to the processor side generated during the work,
A suitable shape that can effectively protect the substance from scattering is realized for the half-morning glory shape 9. As a result, the width of the curved portion is adjusted by adjusting the manner of applying the force at the time of bending, whereby the amount of scattering of the fine powdery substance to the processor side is reduced.
At this point it is possible to protect and adjust to an arbitrary amount.

The work cover described in the above embodiment is one of the objects of the present invention, which is to "maintain a high recovery rate of the fine powdery substances scattered especially to the processor side". Is applied as it is. That is, in this configuration, `` the cover has a size enough to cover and cover the palm of the processor sufficiently, the shape of the top is formed in a fan shape, and a finger is inserted through the left and right sides of the portion to form a cover inside the cover. A pair of holes cut in a cross shape or a double cross shape for gripping a workpiece is provided, and by passing a pair of thumb and forefinger through the holes, the cover can be fitted to the palm. At the same time, by gripping the workpiece with the pair of fingers, the palm portion of the cover and the fan-shaped portion of the top are both curved inward, so that the portion is directed toward the processor generated during work. Is formed so as to be able to form a half-bosh glory that can protect the fine powdery substance from scattering. ”As a result, both the palm-shaped part 2 and the fan-shaped part 3 formed in the half-boshed form are concavely inward. By bending By protecting and controlling the scattering of the fine particles, it is sufficiently possible to maintain the recovery rate of the fine particles scattered to the processor at a high level, and it is clear that the object is achieved. . In particular, by bending the substantially circular portion 2 into a dish shape, it becomes easy to collect the fine and granular material when the workpiece 4 is polished or cut by the substantially circular portion 2.

FIG. 5 is a perspective view showing another embodiment of the work cover of the present invention. The work cover 1 'of this embodiment differs from that of the above embodiment in that the lower part of the substantially circular palm portion 2 is bent into a cylindrical shape to close the joint, thereby forming a cylindrical portion 2'.
