[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

The outer side of 402 is meshed with a transmission wheel 403 through a tooth groove, and the transmission wheel 403 is connected to the protective shell 3 axis, and the outer side of the transmission wheel 403 is meshed with an inner shell 404 away from the gear ring 402. The inner shell 404 can drive the elastic telescopic frame 405 to rotate, and the side wall of the inner shell 404 is formed with a tooth groove meshing with the transmission wheel 403. A plurality of elastic telescopic frames 405 are equidistantly installed around the inner shell 404, and the movable ends of the elastic telescopic frames 405 are connected by springs, and the elastic force of the spring is less than the centrifugal force when the inner shell 404 rotates, and the elastic telescopic frames 405 are installed in an inclined state, and the inclined elastic telescopic frames 405 can scrape part of the soil to the inner shell 404.

[0026] like Figure 4-Figure 6As shown, a locking assembly 5 is connected between the turntable 401 and the drill bit 2, and the locking assembly 5 includes multiple groups of elastic hinges 501 fixedly connected to the turntable 401, so that the dividing plate 502 can be rotated in the vertical direction through the elastic hinges 501, and each group of elastic hinges 501 is connected to the outer side of a dividing plate 502, so that the drilling requirements of drill bits 2 with different diameters can be met through multiple groups of dividing plates 502, and the top of the protective shell 3 can be closed through the dividing plate during the drilling sampling process.

[0027] like Figure 1-Figure 2 As shown, the handheld drill 1 includes a connecting shaft 103 connected to the drill bit 2, and an engine 102 is installed at the bottom end of the connecting shaft 103, so that the engine 102 can drive the drill bit 2 to rotate through the connecting shaft 103.

[0028] like Figure 1-Figure 2 As shown, a frame 101 is fixed to the bottom of the engine 102, and a connecting shaft 103 passes through the frame 101, so that during the drilling sampling process, the staff can hold the frame 101 and press down the handheld drill 1 to descend.

[0029] like Figure 1-Figure 2 As shown, a connection assembly 6 is installed between the protective shell 3 and the frame 101, and there are two groups of connection assemblies 6, which can connect the protective shell 3 and the frame 101 through the connection assembly 6 and ensure the stability of the handheld drill 1 when it is descending.

[0030] like Figure 1-Figure 2 As shown, the connecting assembly 6 includes a guide rod 601 with a top end penetrating the frame 101, and the guide rod 601 is slidably connected to the frame 101, so that the frame 101 can move along the guide rod 601, thereby ensuring that the handheld drill 1 can move vertically.

[0031] like Figure 1-Figure 2 As shown, a return spring 602 is arranged on the outside of the guide rod 601, the bottom end of the return spring 602 is fixedly connected to the protective shell 3, and the top end of the return spring 602 is in contact with the frame 101, so that the return spring 602 can be continuously compressed during the descent of the handheld drill 1, and the return spring 602 is stretched and reset during the ascent of the handheld drill 1.

[0032] Working principle of the device: When the device is used, the staff first places the protective shell 3 at the position where the drilling and sampling are required, and then connects the drill bit 2 with the connecting shaft 103 on the handheld drill 1. After the connection is completed, the bottom end of the drill bit 2 is first inserted into the dividing plate 502 in the locking assembly 5 until the bottom end of the drill bit 2 is in contact with the ground. At the same time, the dividing plate 502 is subjected to force and can be rotated through the elastic hinge 501 to meet the use requirements of drill bits 2 of different diameters. The dividing plate 502 is subjected to the elastic hinge 501 to clamp the drill bit 2, and can connect the frame 101 and the connecting assembly 6 at the same time. The guide rod 601 on the connecting assembly 6 can pass through the frame 101;

[0033] After the connection is completed, the engine 102 on the frame 101 drives the drill bit 2 to rotate through the connecting shaft 103. The staff holds the frame 101 and presses downward to achieve drilling and sampling by the drill bit 2. During the sampling process, the protective shell 3 can effectively prevent flying stones from hitting the staff, thereby improving safety. At the same time, multiple partition plates 502 can seal the top of the protective shell 3 to prevent dust from overflowing.

[0034] The clamping connection between the dividing plate 502 and the drill bit 2 can drive the turntable 401 in the cleaning assembly 4 to rotate along the protective shell 3 during the rotation of the drill bit 2. The turntable 401 drives the gear ring 402 to rotate and the inner shell 404 can be rotated through the transmission wheel 403. The rotation of the inner shell 404 can drive the elastic telescopic frame 405 to rotate, and the centrifugal force generated during the rapid rotation of the inner shell 404 can make the movable end of the elastic telescopic frame 405 move toward the drill bit 2 until it contacts the drill bit 2. During the rotation, the soil around the drill bit 2 is cleaned and flattened by the stretched inclined elastic telescopic frame 405, and part of the soil can be scraped to the inner shell 404 to avoid soil accumulation around the borehole and prevent soil from easily falling into the borehole, affecting the accuracy of subsequent coring sampling.

[0035] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
