Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 4 As shown, a geological prospecting hammer includes a hammer handle 1, which is a vertically elongated strip. Hammer heads are detachably mounted on the left and right sides of the upper end of the handle 1, respectively. The two hammer heads are a first hammer head 2 on the left and a second hammer head 3 on the right. The first hammer head 2 and the second hammer head 3 may have the same or different shapes. In this embodiment, the first hammer head 2 is a cone shape with a pointed left end, and the second hammer head 3 is cylindrical. The specific shape of the hammer heads can be set according to usage requirements. By setting multiple first hammer heads 2 and second hammer heads 3 with different shapes, various different usage requirements can be met by installing different first hammer heads 2 and second hammer heads 3 on the hammer handle 1.

[0029] like Figure 2As shown, the two hammer heads are integrally formed with cylindrical positioning posts 4 at their close ends. The upper left and right sides of the hammer handle 1 are respectively provided with positioning grooves 5 that match the positioning posts 4. When installing the first hammer head 2 and the second hammer head 3, the positioning posts 4 on the hammer heads are inserted into the corresponding positioning grooves 5, thereby improving the stability of the connection between the hammer head and the hammer handle 1.

[0030] A laterally extending threaded rod 6 is welded to the right end of the positioning post 4 on the first hammer head 2. The threaded rod 6 is coaxially arranged with the positioning post 4. The upper end of the hammer handle 1 has a through hole 7 for the threaded rod 6 to pass through. The through hole 7 laterally connects the positioning grooves 5 on the left and right sides, and the diameter of the positioning grooves 5 is larger than the diameter of the through hole 7. The left end of the positioning post 4 on the second hammer head 3 has a threaded hole 8 that matches the threaded rod 6. During installation, the second hammer head 3 is screwed onto the threaded rod 6, and the first hammer head 2 and the second hammer head 3 clamp the hammer handle 1 to make the connection between the three secure. The first hammer head 2 and the second hammer head 3 are connected by the threaded rod 6, which facilitates the disassembly and assembly of the hammer heads and makes them easy to carry.

[0031] like Figure 2 and Figure 3 As shown, to prevent the threaded connection between the first hammer head 2 and the second hammer head 3 from loosening during the hammering process, a sliding cavity 9 extending radially and vertically along the through hole 7 is provided inside the hammer handle 1. The upper end of the sliding cavity 9 is connected to the through hole 7, and a locking pin 10 is slidably installed inside the sliding cavity 9. A pin groove 11 is provided on the outer wall of the threaded rod 6 for one end of the locking pin 10 to be inserted into. A spring 12 is provided between the lower end of the locking pin 10 and the bottom wall of the sliding cavity 9 for pushing the locking pin 10 upward into the pin groove 11. In addition, to facilitate the movement of the locking pin 10, a lever 15 perpendicular to it is screwed onto the locking pin 10. A strip hole 16 is provided on the hammer handle 1 for the lever 15 to pass through. The length of the strip hole 16 extends vertically. Moving the lever 15 up and down along the strip hole 16 will cause the locking pin 10 to move up and down.

[0032] In addition, such as Figure 4 As shown, a locking block 13 is integrally formed on the inner peripheral wall of the positioning groove 5 corresponding to the second hammer head 3, and a locking groove 14 is provided on the positioning post 4 corresponding to the second hammer head 3 for the locking block 13 to be inserted into; when the locking block 13 is inserted into the locking groove 14 and the second hammer head 3 is screwed onto the threaded rod 6, the pin groove 11 is aligned with the locking pin 10.

[0033] When installing the first hammer head 2 and the second hammer head 3, first insert the positioning pin 4 on the second hammer head 3 into the positioning groove 5 on the right side of the hammer handle 1, and at the same time, make the locking block 13 in the right positioning groove 5 engage with the locking groove 14 of the positioning pin 4 of the second hammer head 3, thereby restricting the rotation of the second hammer head 3; push the lever 15 down to make the upper end of the locking pin 10 disengage from the through hole 7, and then pass the threaded rod 6 on the first hammer head 2 through the through hole 7 on the hammer handle 1 to the right and screw it into the threaded hole 8 of the second hammer head 3, and tighten the threaded rod 6 until the first hammer head 2 is fully engaged. The positioning pin 4 on the head 2 is inserted into the positioning groove 5 on the left side of the hammer handle 1. The first hammer head 2 and the second hammer head 3 clamp the hammer handle 1. At the same time, the pin groove 11 on the threaded rod 6 rotates to align with the locking pin 10. Then, the spring 12 pushes the locking pin 10 to move upward and into the pin groove 11, which restricts the rotation of the first hammer head 2 and the threaded rod 6. Thus, when the first hammer head 2 and the second hammer head 3 are installed in place, neither the first hammer head 2 nor the second hammer head 3 can rotate, thereby preventing the threaded connection between the first hammer head 2 and the second hammer head 3 from loosening.

[0034] A rubber pad 17 is provided between the end face of the positioning post 4 and the inner wall of the corresponding positioning groove 5 to further prevent the threaded connection between the first hammer head 2 and the second hammer head 3 from loosening.

[0035] A pry bar 18 can be detachably installed at the lower end of the hammer handle 1. A stud 19 is welded to the upper end of the pry bar 18. A screw hole 20 matching the stud 19 is provided at the lower end of the hammer handle 1. In this embodiment, the pry bar 18 is a tapered shape with a pointed lower end. The pry bar 18 can also be designed into other shapes according to the usage requirements. By installing the pry bar 18 at the lower end of the hammer handle 1, the rock crevice can be pried open by the pry bar 18, which has multiple functions.

[0036] The hammer handle 1 is equipped with a scale 21 for easy measurement.

[0037] The lower outer side of the hammer handle 1 is provided with an anti-slip rubber sleeve 22, which plays a role in preventing slipping and shock absorption when holding the hammer handle 1.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
