Description
Technical field
The present invention relates to the technical field of geological exploration, and in particular to a kind of Multifunction geological hammer.
Background technology
Geologic hammer is one of geologist's " three treasured " (geologic hammer, compass and magnifying glass), is also geological work
One of basic tool, it is main that rock is carried out using geologic hammer to strike chisel, in order to obtain the sample of rock.Geologic hammer, Duo Shuoyi
End is rectangle or square, and the other end is in pointed or wedge shape.
In the wild in geological prospecting work, especially during basic geology charting, geological work personnel are needed to rock
Stone carries out taking sample, then packs to take back the research work of indoor carry out next step, and geologic survey mistake in the wild
Need to enter line label to sample bag in journey, and the sample of collection is simply described；And need to use in the course of the description small
The instrument such as knife and magnifying glass, pocket knife is used for the test of hardness of mineral, and magnifying glass is used to observe specific mineral to determine rock
Type；So needing to carry pocket knife, geologic hammer, magnifying glass and compass and other items during geology ground observation；Pocket knife and put
Big mirror and other items is easily lost because own vol is smaller, especially in the field environment, along with geological observation journey
Sequence it is relatively complicated, it is necessary to work also the more something lost for often causing article fall.Once it is lost under wild environment and is difficult
Go to find.For this it is thought that can be integrated geologic hammer with pocket knife and magnifying glass, so in the wild in the course of work only
Carrying geologic hammer is needed just to facilitate a lot.It is real that Patent No. CN206084958U Chinese patent discloses a kind of field geology
Exploration hammer is commonly used, prolonging handle is arranged to hollow, while internal cavities are separated into first chamber and second chamber, wherein first
Chamber is used to store pocket knife and pencil, and second chamber is used to store geologic map；Pocket knife is still used with hammer body and divided in this way
Body formula can not solve pocket knife something lost and fall the problem of losing；And patent disclosed in Patent No. CN105397724 similarly exist it is upper
State problem；The Chinese patent of Patent No. 200920040379.3 discloses a kind of Multifunction geological hammer, and magnifying glass is folded into
Although realizing the integrated design of magnifying glass and hammer handle in hammer handle, using the collapsible magnifying glass during rock is tapped
Damage is easily caused, above-mentioned design does not have practicality in fact；Though and Patent No. CN205380635U Chinese patent
So disclose the integrated design of magnifying glass and hammer handle, it is to avoid hammer the shatter of magnifying glass during rock again, but amplification
Mirror is still exposed to outside, it is impossible to be prevented effectively from the abrasion that the rock shot down is caused to magnifying glass.
And the tup and hammer handle of geologic hammer on the market are typically using integration manufacture at present, such design makes geology
Hammer is overall to take larger space, so as to cause to carry inconvenient；Patent No. CN105397724 Chinese patent discloses one
Multifunctional portable geology hammer is planted, folding position is provided with its hammer handle；Although this design can be convenient for carrying geologic hammer,
But the presence in use due to folding position is easily caused using difficult, in particular for tapping hard rock
When, the hammer handle of split may realize automatic closure after rock is tapped, and cause tong to occur；And Patent No.
CN205380635U Chinese patent discloses a kind of Multifunction geological hammer, and its hammer handle top sets and set on external screw thread, tup
Internal thread completes to connect by internal thread and externally threaded cooperation, although above-mentioned design can realize the easy to disassemble of tup,
It is the problem of still suffering from inconvenient in use, because limited using its attachment force is threadedly coupled, it is easy to cause stripped thread
So that tup drops；So above-mentioned design does not have practicality.To sum up, prior art does not solve geologic hammer not side
Portable belt and field need to carry the loss article that excessive article is caused, the problem of operating efficiency is low.
