[0055] The handheld drill 1 can be detachably fixedly mounted on the drilling support 2. The handheld drill 1 is used to drive the replaceable front end tool 3 to rotate. The drilling support 2 is used to drive the handheld drill 1 to drive the replaceable front end tool 3 to feed axially to complete the drilling work.

[0056] The sample packaging container 4 is detachably fixedly mounted on the drilling support 2;

[0057] During drilling work, the replaceable front-end tool 3 is assembled into an integral structure and fixedly connected to the handheld drill 1; in other cases, it is stored and fixed in the sample packaging container 4;

[0058] The structure of the drilling support 2 includes two states: unfolded and folded. During drilling work, the drilling support 2 is unfolded and supported on the drilling surface, thereby providing structural support. In other cases, the drilling support 2 remains folded to facilitate the operator to carry and transport.

[0059] There are two states for astronauts to use the lunar portable intelligent drilling device, such as Figure 1 The figure shows the working state, where the astronaut can complete the drilling operation by operating the handheld drill 1 with the assistance of the drilling support 2. Figure 2 The picture shows the folded state. After folding, the envelope size is reduced, making it easier for astronauts to transport and carry.

[0060] like Figure 3 As shown, the handheld drill 1 includes: a rotary impact mechanism 11, an intelligent interaction module 12, an energy module 13, a quick-change connector 14, a foldable handle 15 and a drill housing 16;

[0061] The rotary impact mechanism 11 is the power output source of the handheld drill, and is fixedly mounted on the drilling housing 16. It is driven by a single motor and realizes the rotary impact function through the design of the internal spring, cam and shaft system;

[0062] The intelligent interaction module 12 is mounted on the outer wall of the drilling rig housing 16;

[0063] The intelligent interaction module 12 receives the measurement while drilling parameters sent by the built-in measurement module of the replaceable front-end tool 3 in real time through the WiFi interface, and generates a virtual borehole through the data model and displays it on the operation panel of the intelligent interaction module 12, thereby visualizing the drilling process.

[0064] The energy module 13 is installed on the side of the drilling rig housing 16; the energy module 13 is used to provide energy supply for the rotary impact mechanism 11 and the drilling mechanism 23 in the drilling bracket 2; a charging interface is provided inside the energy module 13, which can be connected to equipment such as a lunar rover and a lander for charging;

In the embodiment of the present invention, the two foldable handles 15 are fixedly connected to the top of the housing and the middle and lower part of the housing of the rotary impact mechanism 11 respectively.

[0068] By adjusting the angle of the foldable handle 15, the handheld drill 1 is connected to the guide slider 22 in the drilling bracket 2 through the quick connection structure on the drill housing 16, so as to realize the hanging deep drilling mode and the handheld shallow drilling mode. That is, according to the different use modes of the handheld drill 1 by the astronauts, the deep drilling of the lunar soil can be realized vertically, and the rock breaking sampling of the exposed surface rocks can be realized horizontally.

[0075] The foot pedal 25 is mounted on the telescopic bottom plate 24, and the telescopic bottom plate 24 is connected to the foldable guide rail 21 through a hinge. The operator steps on the foot pedal 25 to ensure the stability of the drilling bracket 2 by using his own weight;

[0076] A retractable scissor mechanism 26 is designed on the opposite side of the telescopic bottom plate 24 to ensure the stability of the drilling rig support 2 after it is unfolded. The scissor mechanism 26 is connected to the foldable guide rail 21 by connecting the support rod 27 to enhance stability.

In the embodiment of the present invention, a structure for storing a replaceable front-end tool 3 is provided inside the sample packaging container 4. The replaceable front-end tool 3 is initially placed inside the sample packaging container 4. Different replaceable front-end tools 3 are designed for different working objects such as shallow lunar soil, deep lunar soil, surface rock, etc. Specifically, they are:

[0080] b. A deep drilling tool with a microstructure inside, which is a structural rod. The microstructure inside is conducive to deep sampling of lunar soil. After the drilling is completed, the drilling tools need to be taken out from the deep layer in sequence, and the drilling tools containing lunar soil inside are placed in the sample packaging container 4;

[0081] In addition, a variety of different drilling tools have been designed, such as grinding wheels, impact steel drills, and imitation Luoyang shovels. Lunar samples can be collected by switching drilling tools.

[0085] The top of the soft bag holder 42 is fixedly connected to the inner side of the sealing cover 43; an annular groove is processed on the soft bag holder 42, which is used to store the soft bag wrapped with the drilling sample after the shallow drilling tool completes the drilling work; when the shallow drilling tool with built-in soft bag is used for operation, after the drilling is completed, the astronauts will wrap the soft bag wrapped with the sample into the annular groove of the soft bag holder 42 to achieve stable storage.

[0086] When a deep drilling tool with an internal microstructure is used for deep sampling operations, the replaceable front-end tool 3 containing lunar soil is returned to the original storage position after drilling is completed.
