State；
Fig. 2 is the structure diagram of the dust-proof device in drill process described in the utility model, is not work in figure
State；
Fig. 3 is the side view of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2 and Figure 3, the dust-proof device in a kind of drill process of the utility model, perforating device include
Puncher 1 and drill bit 2, drill bit 2 are installed on the head of puncher 1, and dust-proof device includes retainer ring 3, clamp device, annular
Cloth 5 and elastic metallic curved bar 4, the medial surface of retainer ring 3 are provided with internal thread, are provided with the head of puncher 1 and internal thread
The external screw thread of adaptation, retainer ring 3 are detachably connected by screw thread and puncher 1, and the inner of multiple elastic metallic curved bars 4 is with fixing
Ring 3 is fixedly connected, and the interior edge of annular cloth 5 is fixedly connected with the inner of elastic metallic curved bar 4, outer and the elasticity gold of annular cloth 5
The outer end for belonging to curved bar 4 is fixedly connected, and for elastic metallic curved bar 4 in non-stress, the arc core of elastic metallic curved bar 4 is positioned at close
The side of drill bit 2, annular cloth 5 are located at the inner side of elastic metallic curved bar 4, and the lateral surface and elastic metallic curved bar 4 of annular cloth 5,
The quantity of elastic metallic curved bar 4 is 6, and 6 elastic metallic curved bars 4 are uniformly fixed on using the central axes of retainer ring 3 as axle center
Determine on ring 3, clamp device includes retainer plate 6 and fastening line, and multiple retainer plates 6 are fixedly connected with elastic metallic curved bar 4 respectively, tightly
Solidus sequentially passes through multiple retainer plates 6, and retainer plate 6 is located at the middle-end of elastic metallic curved bar 4, is set on annular cloth 5 multiple transparent
Perspective frame.
The operation principle of dust-proof device in the utility model drill process is as follows：
When needing to install dust-proof device, the external screw thread being adapted to 3 internal thread of retainer ring is attacked at the head of puncher 1
, can be fixed connection by screw thread.
