Above-mentioned technical scheme carries out drilling operation, through fixing drill bit fixing device's foot nail on the rock surface to guarantee that telescopic center and the circular that needs to bore remain concentric, pass the centre bore with the drill bit again, then hand drill bit carries out drilling operation, can guarantee that the drill bit can not take place to beat in the course of the work, guarantees drilling hole site precision, improves the efficiency of construction. However, if the drill bit passes through the central hole and is unstable in hand, the drill bit contacts the sleeve during working, so that the sleeve is damaged, and the service life of the drill bit fixing device is reduced.

Disclosure of Invention

The utility model aims to solve the problems in the prior art, and provides the air drill for rock and soil exploration, which can assist in positioning the whole air drill, avoid jumping of the drill bit, assist the hand to hold the air drill stably and avoid deviation of the whole air drill.

The utility model solves the technical problems by adopting the technical scheme that: the pneumatic drill for rock and soil investigation comprises a pneumatic drill body, a pneumatic drill handle arranged at the right end of the pneumatic drill body, a handheld handle arranged at the middle part of the pneumatic drill body, a drill chuck arranged at the head of the pneumatic drill body, and a drill bit arranged at the head of the drill chuck.

For further perfection, slip ring left end fixedly connected with protection casing, fixed frame fixed connection is on the protection casing, and the rubble that the protection casing can avoid drilling to produce splashes, and the pneumatic drill uses more convenient.

Further perfects, handheld handle left end fixedly connected with baffle avoids the rubble to splash on the workman's hand, causes the workman to be injured for the pneumatic drill uses safelyr.

Further perfection, fixedly connected with anticreep ring in the staple outside avoids the staple to break away from the fixed frame for the device uses more convenient.

Further perfection, the drill outside is equipped with fixed connection and is equipped with the guide ring on the protective cover, and guide ring inner diameter is greater than the drill diameter for the guiding effect to the drill is better, avoids the jump that can be better.

Further perfection, the screwed ring is installed to handheld handle left end, and fixed ring threaded connection is in the screwed ring outside, and fixed ring demountable installation is on handheld handle for the life of device is longer, and it is more convenient to use.

The beneficial effects of the utility model are as follows: can carry out assistance-localization real-time to the pneumatic drill is whole, avoid the drill bit to take place to beat, and can assist the hand to hold the pneumatic drill steady, avoid the pneumatic drill whole to take place the skew, fix on rock through the staple, and guarantee the center of sliding the ring and need the circular keeping concentricity of drilling, can hold the drill bit and carry out drilling operation, position through sliding the ring location pneumatic drill, avoid the pneumatic drill handheld unstable skew that takes place, avoid the drill bit to jump, guarantee drilling hole site precision, improve the efficiency of construction, the rubble that the protection casing can avoid drilling to produce splashes, the pneumatic drill uses more convenient, the baffle avoids rubble to splash on hand the workman, cause the workman to be injured, make the pneumatic drill use safer, the guide ring is better to the guiding action of drill bit, can be better avoid jumping to bore, fixed ring demountable installation is on handheld handle, make the life of device longer, it is more convenient to use.
