[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are merely used for the purpose of facilitating the description of the present application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application. Figure 5As shown, the depth of the through groove 3 is greater than the length of the ground pile, so as to avoid the collision between the ground pile and the bottom of the through groove 3, and to avoid the damage of the through groove 3.

[0027] As shown in the drawings, Figure 5 As shown, the cover 2 is connected with a shielding plate 5 for shielding the receiving groove 4, and the shielding plate 5 is connected with the cover 2 by sewing, so as to realize the folding of the shielding plate 5 on the cover 2. At the same time, the end of the shielding plate 5 away from the rotating connection is detachably connected with the cover 2. The shielding plate 5 and the cover 2 are provided with a zipper structure, and the detachable connection between the shielding plate 5 and the cover 2 is realized through the zipper structure, so that the opening and change of the receiving groove 4 can be controlled through the shielding plate 5.

[0028] The opening of the through groove 3 for the embedding of the ground pile is rotatably provided with a clamping piece 6. The clamping piece 6 is provided in a bent structure, and the rotation point is located at the bending portion of the clamping piece 6. Two clamping pieces 6 are symmetrically arranged on both sides of each opening, so that during the embedding of the ground pile into the through groove 3, the ground pile will abut against the clamping piece 6, thereby pushing the clamping piece 6 to rotate, so that the one end of the clamping piece 6 abuts against the ground pile, thereby forming an initial fixing effect.

[0029] As shown in the drawings, Figures 1-5 The clamping piece 6 is divided into a clamping portion and an abutting portion along the bending portion. The clamping portion is provided with a groove 7 for clamping the ground pile, so as to enhance the connection firmness after abutting. The abutting portion is provided with a buffer pad 8, so as to reduce the abrasion of the ground pile after abutting against the clamping piece 6.

[0030] As shown in the drawings, Figures 3-4 The side of the clamping portion close to the instrument box 1 is further provided with a positioning hole 9. The cover 2 is slidably provided with a positioning guide column 10 for embedding into the positioning hole 9. Through the cooperation of the positioning hole 9 and the positioning guide column 10, the position of the clamping piece 6 after abutting is fixed, so as to ensure the clamping effect.

[0031] As shown in the drawings, Figures 1-4 The side of the cover 2 close to the instrument box 1 is provided with a pushing assembly. The pushing assembly is in transmission connection with the positioning guide column 10. When the cover 2 is not closed with the instrument box 1, the pushing assembly protrudes from the surface of the cover 2. When the cover 2 is closed, the instrument box 1 abuts against the pushing assembly, and the pushing assembly is displaced, so that the pushing assembly drives the positioning guide column 10 to embed into the positioning hole 9 to form a fixation. When the ground pile cannot be completely embedded, the positioning guide column 10 cannot be smoothly embedded into the positioning hole 9, and the cover 2 cannot be closed, so as to prompt the user to adjust the storage of the ground pile.

[0032] As shown in the drawings, Figures 4-5As shown, the pushing component includes a rotating rod 11 rotatably mounted on the cover 2 and a folding rod 12 hinged at both ends to the rotating rod 11 and the positioning guide post 10, respectively. When the cover 2 is not closed with the instrument body 1, the hinge connection between the rotating rod 11 and the folding rod 12 protrudes from the surface of the cover 2. When the cover 2 is closed, the hinge connection between the rotating rod 11 and the folding rod 12 will abut against the instrument body 1, thereby achieving the effect of pushing the positioning guide post 10 to move.

[0033] And as Figure 1 As shown, the instrument box 1 has a rigid outer edge at the abutment of the hinge connection point, which provides good support. At the same time, a roller 13 is rotatably mounted on the positioning pin at the hinge connection point of the rotating rod 11 and the folding rod 12. The roller 13 reduces wear between the roller and the rigid outer edge. Meanwhile, the rigid outer edge has an inner groove 7 at the position of the roller 13, which provides a space for the rotating rod 11, the folding rod 12 and the roller 13, ensuring the normal closing effect of the box cover 2.

[0034] like Figures 3-4 As shown, the folding rod 12 is configured as a two-section structure. The two sections of the folding rod 12 are hinged to the rotating rod 11 and the positioning guide post 10 respectively, and the two sections of the folding rod 12 are rotatably connected to each other, thereby forming a folding effect. The folding effect ensures the stability of the transmission.

[0035] like Figure 4 As shown, the positioning guide post 10 is fixedly connected to the limiting block 17. The cover 2 is provided with a limiting cavity 14 for the limiting block 17 to slide. Through the cooperation between the limiting block 17 and the limiting cavity 14, the positioning guide post 10 is prevented from falling off. A magnetic component 15 is fixedly provided on the side of the limiting cavity 14 away from the instrument box 1. A magnetic component 2 16 is fixedly provided on the limiting block 17, which forms a repulsive force with the magnetic component 15. Through the repulsive force, the positioning guide post 10 will stably push the folding rod 12 to move outward when no external force is applied, so that the positioning guide post 10 protrudes from the surface of the cover 2.

[0036] Both magnetic component 15 and magnetic component 2 16 are made of neodymium iron boron magnets. Neodymium iron boron magnets have strong magnetism and are also small in size and light in weight, thus giving magnetic component 15 and magnetic component 2 16 good performance.

[0037] Working principle: when storage, remove the blocking plate 5, put the test line into the storage groove 4, then fix the blocking plate 5, and then embed the ground pile into the through groove 3, in the process of embedding the ground pile, the ground pile abuts against the abutting portion of the clamping piece 6, and pushes the abutting portion to rotate, so that the clamping portion rotates, when the ground pile is completely embedded, the clamping portion forms clamping and fixing of the ground pile, then cover the box cover 2, in the process of covering the box cover 2, the roller 13 abuts against the instrument box body 1, as the angle between the box cover 2 and the instrument box body 1 becomes smaller, the position of the roller 13 moves, so that the rotating rod 11 rotates, and pushes the positioning guide column 10 to move towards the clamping piece 6 through the folding rod 12, and then the positioning guide column 10 is embedded into the positioning hole 9, so as to fix the position of the clamping piece 6, and ensure the clamping and fixing effect of the ground pile.
