Kind Code:
B2
Abstract:
To provide an indoor cutting device capable of preventing a dusty state during the operation.SOLUTION: An indoor cutting device has a driving device 2, comprising a connector 10, and a reduction gear 5 which are attached to a static shell 3. Because of a large space of a storage cavity of the cutting device, an extending/contracting part of a first fan-shaped dust-proof shell does not close a first circular hole of a second fan-shaped dust-proof shell, and a dust suction device connected to the cutting device can continuously suck dust. Because a second inclined plane is provided to a guide plate, scattered small stones and dust can be put in the storage cavity of the second fan-shaped dust-proof shell by the guide plate during a cutting process, in the cutting device. Because the part near the first circular hole of the storage cavity of the second fan-shaped dust-proof shell becomes larger, the storage cavity can store much more stones and dust, to effectively suck dust.SELECTED DRAWING: Figure 1
