The working principle is as follows:

firstly, because the motor 11 can generate strong vibration force when being started, a user supports the motor 11 through the connecting handle 12 to avoid the left-right shaking of the motor 11, and because the connecting handle 12 consists of a peripheral sponge shock-absorbing sleeve and an internal cylinder, when the motor 11 generates vibration force and transmits the vibration force to the hand of the user through the connecting handle 12, the vibration force can be absorbed by the sponge shock-absorbing sleeve, so that the situation that the user loosens the hand due to overlarge vibration force is prevented, and the connecting handle 12 is convenient for the user to better support the motor 11;

then, when the motor 11 has a current source, the user can hold the connecting handle 12 to drive the motor 11 and the rotating shaft 13 to move towards the top of the connecting column 2, so that the rotating shaft 13 is inserted into the insertion groove 201 at the top of the connecting column 2, then hold the bolt 9 to penetrate through the top of the connecting column 2 and the corresponding hole of the rotating shaft 13, finally rotate the nut 10 clockwise to fix the bolt 9, and when the bolt 9 is fixed, the rotating shaft 13 and the insertion groove 201 at the top of the connecting column 2 are also fixed, so that when the motor 11 is started to drive the rotating shaft 13 to rotate, the rotating shaft 13 can drive the connecting column 2 to rotate correspondingly through the bolt 9 and the nut 10, and the connecting column 2 rotates to drive the collecting cavity 3 and the drill bit 4 to rotate together, so that the effect of driving the drill bit body 1 to drill and sample is achieved through the motor 11, and when the motor 11 does not have a current source, the user can penetrate the manual rotating handle 5 through the through hole 202 of the connecting column 2, fix the manual rotating handle 5 and the through hole 202 by rotating the limiting ring 6, and then manually drive the connecting column 2 and the whole drill bit 1 to drill and sample by the manual rotating handle 5, so that the arrangement of the splicing mechanism is convenient for the user to operate the whole drill bit 1 under different conditions, and the user can correspondingly adjust the power source of the whole drill bit 1;

then, when a user needs to penetrate the manual rotating handle 5 through the through hole 202 of the connecting column 2, the two limiting rings 6 can be moved from the two sides of the manual rotating handle 5 to the middle threaded column 502 respectively, and when the limiting rings 6 move to the threaded column 502, the limiting rings 6 are rotated and moved to the two sides of the middle through hole 202 along with the threads on the two sides of the threaded column 502 until the limiting rings 6 cannot move to the middle continuously, and meanwhile, the manual rotating handle 5 is limited by the limiting rings 6 on the two sides of the through hole 202 and cannot move left and right, so that the situation that the user generates displacement when operating the manual rotating handle 5 is avoided;

next, when the user inserts the manual rotating handle 5 through the middle of the connecting column 2, the user can place the hand at the anti-slip sleeve 502, and the anti-slip sleeve 502 is made of rubber materials with good anti-slip effect, so that when the user holds the hand to generate sweat gaps, the anti-slip sleeve 502 can increase the friction between the connecting column 2 and the hand of the user, and the situation that the connecting column 2 slides off due to the sweat on the hand of the user is avoided;

finally, when a user wants to use the sampling mechanism, the user holds the push handle 8 to drive the push plate 14 to move upwards along with the sliding groove 7, then holds the drill bit 4 to move upwards along the collection cavity 3, when the internal thread 401 of the drill bit 4 is attached to the external thread 301 of the collection cavity 3, the user rotates the drill bit 4 clockwise to move upwards to be in threaded fixation with the collection cavity 3, the same inner wall of the drill bit 4 also seals the outer wall of the collection cavity 3 in an attaching manner, then the drill bit 4 is driven by the splicing mechanism to rotate clockwise to move underground through the teeth 402, correspondingly, when the drill bit 4 moves downwards, the collection cavity 3 is driven to move together, so that the sample soil enters the collection cavity 3, when the user takes out the sample soil in the collection cavity 3, the user can firstly rotate the drill bit 4 anticlockwise to take out the sample soil, and then holds the push handle 8 to drive the push plate 14 to move downwards along with the sliding groove 7, and collect the inside sample soil in chamber 3 and also can come out corresponding length to the outside when push pedal 14 moves down to the person of facilitating the use takes out the sample soil of corresponding length from collecting chamber 3 inside according to the condition, and the person of facilitating the use takes out different length sample soil in batches and detects, and it is troublesome when having avoided the user to dismantle drill bit 4 can take out sample soil, and this is exactly this kind of geological engineering special sampling drill bit's theory of operation.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
