[0025] Example: See Figures 1 to 7According to an embodiment of the utility model, a technical solution is provided: a drilling tool for geological exploration, comprising a shell 1, a cavity 2 is defined inside, a movable plate 3 is arranged in the cavity 2; a drill bit 4 is arranged at the bottom of the movable plate 3, a motor 5 is installed on the top of the movable plate 3, the output end of the motor 5 is coaxially fixed with the drill bit 4, and an opening 7 suitable for the drill bit 4 to move in and out of the cavity 2 is opened at the bottom of the shell 1; a driving mechanism 8 is used to drive the movable plate 3 to move along the height direction of the shell 1; at least two storage boxes 9 are arranged at intervals on the peripheral side wall of the shell 1 On the storage box 9, a positioning plate 11 is provided in the storage box 9, and the first end of the positioning plate 11 is rotatably connected to the storage box 9 through an axis 10. The positioning plate 11 has a folded state or an unfolded state on the storage box 9. When the positioning plate 11 is in the folded state, it is located in the storage box 9. When the positioning plate 11 is in the unfolded state, it is perpendicular to the storage box 9. A positioning hole 12 is opened on the positioning plate 11; and a locking mechanism 13 is provided between the positioning plate 11 and the storage box 9. When the positioning plate 11 is in the unfolded state, the locking mechanism 13 is used to maintain the positioning plate 11 is in the unfolded form; the locking mechanism 13 includes a fixed shaft 18, a movable shaft 19, a locking shaft 20, an abutment plate 21 and a spring 22; the fixed shaft 18 is fixed in the storage box 9, and a notch 23 is provided on the peripheral side wall of the positioning plate 11, and the movable shaft 19 is slidably arranged in the notch 23; a connecting member 24 is provided between the movable shaft 19 and the fixed shaft 18, and the two ends of the connecting member 24 are rotatably connected to the movable shaft 19 and the fixed shaft 18 respectively; the movable shaft 19 moves in the notch 23 to the first limit position and the second limit position, when the movable shaft 1 When the movable shaft 19 is located at the first extreme position, the positioning plate 11 is in an unfolded state, and when the movable shaft 19 is located at the second extreme position, the positioning plate 11 is in a folded state; a locking cavity 25 is defined in the positioning plate 11, and the abutment plate 21 is slidably arranged in the locking cavity 25, and the locking shaft 20 is fixed on the abutment plate 21, and the top of the locking shaft 20 movably passes through the positioning plate 11 and extends into the slot 23, and the spring 22 is arranged in the locking cavity 25 and elastically abuts against the abutment plate 21; when the movable shaft 19 is located at the first extreme position, the locking shaft 20 is suitable for limiting the movement of the movable shaft 19.

[0026] When the user needs to perform drilling operations on the drilling tool for geological survey using the above structure, first, align the opening 7 at the bottom of the shell body 1 with the surface position to be drilled, then flip the positioning plate 11 in the storage box 9 to make it in the expanded state. At this time, the bottom surface of the positioning plate 11 will be horizontally aligned with the bottom of the shell body 1, and then, flip the positioning plate 11 to the expanded state. During this process, the movable shaft 19 will slide from the second limit position of the notch 23 to the first limit position of the notch 23. As the movable shaft 19 reaches the first limit position, due to the elastic force of the spring 22, it will push the abutment plate 21 and the locking shaft 20 thereon toward the notch 23 position, so that the locking shaft 20 passes through the locking cavity 25 and reaches the notch 23 to limit the movable shaft 19 from moving to the first limit position. At this time, the abutment plate 21 is moved downward, and the spring 22 is compressed, while driving the locking shaft 20 to enter the locking cavity 25 to allow the movable shaft 19 to move to the first limit position. The movable shaft 19 enters the first limit position. When the movable shaft 19 is in the first limit position, the abutment plate 21 is released, so that it is abutted and moved upward by the spring 22, so as to drive the locking shaft 20 to move up to the notch 23, and limit the movement of the movable shaft 19 again. At this time, since the movable shaft 19 is restricted from moving, the two ends of the connecting member 24 are respectively constrained by the fixed shaft 18 and the movable shaft 19, thereby forming a stable triangular support structure to limit the external force from flipping the positioning plate 11, so that the positioning plate 11 can be continuously and stably maintained in the expanded shape. Then, a nail or bolt is used to pass through the positioning hole 12 and drive it into the ground surface to fix the positioning plate 11 relative to the ground surface to realize the positioning and fixing of the shell 1. Finally, the movable plate 3 is driven downward by the driving mechanism 8. At the same time, the motor 5 is used to drive the drill bit 4 to rotate, so as to realize the driving of the drill bit 4 downward and the rotation of the drill bit 4 into the ground surface for drilling operations. On the contrary, when the user finishes the drilling operation, he only needs to reverse the operation, that is, remove the nail or bolt from the positioning hole 12, use the locking mechanism 13 to allow the positioning plate 11 to no longer maintain the expanded shape, and then store the positioning plate 11 into the storage box 9 to reduce the occupied area of ​​the positioning plate 11, so as to facilitate the user to carry the shell 1 to the next drilling site.

[0027] In order to drive the movable plate 3 to move along the height direction of the shell 1, in this embodiment, the driving mechanism 8 includes a screw 14, a guide rod 15, a fixed frame 16, a motor 6 and a transmission belt 17; the screw 14 and the guide rod 15 are rotatably arranged in the cavity 2 at intervals, the guide rod 15 movably penetrates the movable plate 3, and the screw 14 penetrates the movable plate 3 and is threadedly connected thereto; the fixed frame 16 is fixed to the top wall of the cavity 2, the motor 6 is fixed on the fixed frame 16, and the transmission belt 17 is sleeved between the output end of the motor 6 and the screw 14; when the user needs to drive the drill bit 4 to move down or up, first, through the forward or reverse rotation of the motor 6, the output end drives the transmission belt 17 to rotate forward or reverse, and the forward or reverse rotation of the transmission belt 17 will drive the screw 14 to rotate forward or reverse, and since the screw 14 is threadedly connected to the movable plate 3, the forward or reverse rotation of the screw 14 will be converted into a linear motion of the movable plate 3 moving down or up along the axial direction of the screw 14 (i.e., the height direction of the shell 1).

[0028] In order to keep the positioning plate 11 in the folded state, in this embodiment, a magnetic member 26 is provided inside the positioning plate 11. When the movable shaft 19 is located at the second extreme position, the magnetic member 26 is suitable for adsorbing the movable shaft 19. When the positioning plate 11 is flipped to the folded state, during this process, the movable shaft 19 will slide along the slot 23 to the second extreme position. At this time, the magnetic member 26 will adsorb the movable shaft 19 to limit the passive movement of the movable shaft 19 due to its gravity. Since the movable shaft 19 is restricted from moving, and the two ends of the connecting member 24 are respectively constrained by the fixed shaft 18 and the movable shaft 19, a straight-line support structure is formed to prevent the positioning plate 11 from being passively flipped, so that it can be continuously maintained in the folded state.

[0029] In order to release the restriction of the locking shaft 20 on the movable shaft 19, in this embodiment, an unlocking mechanism 27 is provided on the positioning plate 11, and the unlocking mechanism 27 is used to drive the abutment plate 21 to approach or move away from the slot 23, so as to drive the locking shaft 20 to enter or exit the slot 23; when the user needs to release the restriction of the locking shaft 20 on the movable shaft 19, the unlocking mechanism 27 drives the abutment plate 21 away from the slot 23, so as to drive the locking shaft 20 to exit the slot 23, thereby allowing the movable shaft 19 to enter or exit the first extreme position.

[0030] In order to release the restriction of the locking shaft 20 on the movable shaft 19, in this embodiment, an unlocking groove 28 connected to the locking chamber 25 is opened on the peripheral side wall of the positioning plate 11, and an unlocking rod 29 is slidably provided in the unlocking groove 28, and the end of the unlocking rod 29 is fixed to the abutment plate 21; when the user needs to release the restriction of the locking shaft 20 on the movable shaft 19, the unlocking rod 29 is pressed downward to make the unlocking rod 29 move downward in the unlocking groove 28, so as to drive the abutment plate 21 to move downward, thereby driving the locking shaft 20 to exit the slot 23, so as to allow the movable shaft 19 to enter or exit the first extreme position.

[0031] Working principle: When the user needs to perform drilling operations, first, align the opening 7 at the bottom of the housing 1 with the surface position to be drilled, then flip the positioning plate 11 in the storage box 9 to make it unfolded. At this time, the bottom surface of the positioning plate 11 will be horizontally aligned with the bottom of the housing 1, and then flip the positioning plate 11 to the unfolded state. During this process, the moving shaft 19 will slide from the second limit position of the notch 23 to the first limit position of the notch 23. When the moving shaft 19 reaches the first limit position, due to The elastic force of the spring 22 pushes the abutment plate 21 and the locking shaft 20 thereon toward the position of the notch 23, so that the locking shaft 20 passes through the locking cavity 25 and reaches the notch 23, so as to limit the movement of the movable shaft 19 to the first limit position. At this time, the abutment plate 21 is moved downward, and the spring 22 is compressed, while driving the locking shaft 20 to enter the locking cavity 25, so as to allow the movable shaft 19 to enter the first limit position. When the movable shaft 19 is in the first limit position, the abutment plate 21 is released, so that it is rebounded by the spring 22. The locking shaft 20 is then moved upward to drive the locking shaft 20 to move upward to the notch 23, and the movement of the movable shaft 19 is restricted again. At this time, since the movable shaft 19 is restricted from moving, the two ends of the connecting member 24 are respectively constrained by the fixed shaft 18 and the movable shaft 19, thereby forming a stable triangular support structure to limit the external force from flipping the positioning plate 11, so that the positioning plate 11 can be continuously and stably maintained in the expanded state. Afterwards, a nail or bolt is driven into the ground through the positioning hole 12 to fix the positioning plate 11 relative to the ground. Fixed to achieve the positioning and fixation of the shell 1, finally, through the forward rotation of the motor 2 6, its output end drives the transmission belt 17 to rotate forward, and the forward rotation of the transmission belt 17 will drive the screw rod 14 to rotate forward. Since the screw rod 14 and the movable plate 3 are threadedly connected, the forward rotation of the screw rod 14 will be converted into a linear motion of the movable plate 3 moving downward along the axial direction of the screw rod 14. At the same time, the motor 1 5 is used to drive the drill bit 4 to rotate, so as to drive the drill bit 4 downward and rotate the drill bit 4 into the ground to perform drilling operations. On the contrary, when the user's drilling operation is completed, he only needs to reverse the operation, that is: remove the nail or bolt from the positioning hole 12, and use the locking mechanism 13 to allow the positioning plate 11 to no longer maintain the expanded shape, and then store the positioning plate 11 into the storage box 9 to reduce the occupied area of ​​the positioning plate 11, so as to facilitate the user to carry the shell 1 to the next drilling site; in order to make the positioning plate 11 continue to maintain in the folded shape, when the positioning plate 11 is flipped to the folded shape, during this process, the movable shaft 19 will slide along the slot 23 to the second extreme position. At this time, the magnetic suction member 26 will adsorb the movable shaft 19 to limit the passive movement of the movable shaft 19 due to its gravity.Since the movable shaft 19 is restricted from moving, and the two ends of the connecting member 24 are respectively constrained by the fixed shaft 18 and the movable shaft 19, an I-shaped support structure is formed to prevent the positioning plate 11 from passively flipping over, so that it can continue to maintain a folded shape; in order to release the restriction of the locking shaft 20 on the movable shaft 19, when the user needs to release the restriction of the locking shaft 20 on the movable shaft 19, the unlocking rod 29 is pressed downward to make the unlocking rod 29 move downward in the unlocking groove 28, so as to drive the abutment plate 21 to move downward, thereby driving the locking shaft 20 to exit the groove 23, so as to allow the movable shaft 19 to enter or exit the first extreme position.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
