Portable extension type outburst mine drill hole mouth drilling cutting collection device

The invention discloses a portable extension type outburst mine drill hole mouth drilling cutting collection device. The device comprises a portable extension rod component, fixed connection components and screen cloth components, wherein the portable extension rod component and the screen cloth components are connected through the fixed connection components, the portable extension rod component is composed of a handle, a first extension rod, a second extension rod and a locking buckle, and the locking buckle enables the first extension rod and the second extension rod to stretch and retract; each screen cloth component is formed by combination of two or more screens. The two drill hole drilling cutting sampling screen cloth components are fixedly connected by means of the portable extension rod component, then the first extension rod and the second extension rod are pulled out, and the screen cloth components are pushed to the position of a drill hole mouth after locking and fixing; after enough drilling cuttings are collected, under the condition that the screen cloth components are kept vertical, the locking and fixing device of the extension rod component is opened to enable the stretched first extension rod and second extension rod to retract to the safe position of a tester, so that the situation that drilling cutting collection length is not enough for the tester is avoided and the danger that people are buried under a collapsed yolk coal wall is avoided.
