[0012] An installation hole is formed in a side wall of the sliding hole facing the hammer handle, and the installation hole is covered by one end of the hammer handle facing the first striking head.

[0013] Further, a plurality of limiting grooves are formed in a side surface of the second striking head facing the installation hole, and the plurality of limiting grooves are linearly arranged in an array along the length direction of the hammer head;

[0014] The one-way locking assembly includes an insertion strip slidably connected with the hammer handle along the length direction of the hammer handle. One end of the insertion strip facing the second striking head is wedge-shaped, and the inclined surface is located on one side of the opening of the sliding hole.

[0015] Further, the hammer handle is composed of two symmetrically arranged support strips spliced together. Two sliding grooves along the length direction of the hammer handle are formed in opposite side surfaces of the two support strips. Two sides of the insertion strip are respectively inserted into the two sliding grooves and are slidably fitted.

[0016] Further, a rack is provided on one side of the insertion strip facing the first striking head, and a gear meshing with the rack. The rack is fixedly connected with the insertion strip. Two ends of the gear respectively penetrate through the side walls of the two support strips and extend outside the two support strips and are rotatably fitted;

[0017] Torsion springs are provided at both ends of the gear. One end of the torsion spring is fixedly connected with one end of the gear, and the other end is fixedly connected with the corresponding support strip.

In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0037] In addition, terms such as "the same" do not mean that the components are required to be absolutely the same, but there may be slight differences. The term "vertical" only means that the positional relationship between components is relatively more vertical compared to "parallel", and does not mean that the structure must be completely vertical, but can be slightly inclined.

[0038] Please refer to Figures 1-5 , the present utility model provides a technical solution: a prospecting hammer for mine geological exploration, including a hammer head and a hammer handle, and the hammer handle is perpendicular to the hammer head. The hammer head is divided into a first striking head 11 and a second striking head 12 along the length direction. One side surface of the first striking head 11 is fixedly connected to one end of the hammer handle, and one end of the second striking head 12 is slidably connected to the first striking head 11 along the length direction of the hammer head;

[0039] An elastic support member is provided between the second striking head 12 and the first striking head 11, and when the elastic support member is in a natural extended state, the end of the second striking head 12 facing away from the hammer handle protrudes from the end face of the first striking head 11 facing the second striking head 12;

[0040] A one-way locking assembly is provided on the second striking head 12 to limit the second striking head 12 from sliding away from the first striking head 11 through the one-way locking assembly.

[0041] The elastic support member is a spring 13. One end of the spring 13 is fixedly connected to the end of the second striking head 12 facing the first striking head 11, and the other end is fixedly connected to the first striking head 11. And the axis of the spring 13 is parallel to the length direction of the hammer head, so as to play a flexible supporting role on the first striking head 11 through the spring 13.

[0042] During use, relevant technicians hold the hammer handle and wave the exploration hammer close to the rock, so that the second striking head 12 strikes the rock. The rock exerts a reaction force on the second striking head 12, causing the second striking head 12 to slide close to the first striking head 11, shortening the overall length of the hammer head. Under the combined action of the inertia of the first striking head 11 and the reaction force on the second striking head 12, the spring 13 is compressed, causing the spring 13 to deform and contract, absorbing and converting part of the kinetic energy of the movement of the first striking head 11 and the second striking head 12 into the elastic potential energy of the spring 13, thereby slowing down the squeezing impact on the palm of relevant technicians and improving the comfort of the exploration hammer. At the same time, the one-way locking assembly restricts the second striking head 12 from sliding away from the first striking head 11, hinders the elastic support member from freely stretching and releasing energy, and restricts the second striking head 12 from reciprocatingly sliding on the first striking head 11 to generate vibration, further improving the comfort of the exploration hammer.

[0043] In this embodiment: A sliding hole 111 extending along the length direction of the hammer head is provided on one end face of the first striking head 11, and one end of the second striking head 12 is inserted into the sliding hole 111 and is in sliding fit.

[0044] By providing the sliding hole 111 on the first striking head 11 and inserting one end of the second striking head 12 into the sliding hole 111, the structural stability after the connection of the first striking head 11 and the second striking head 12 is improved. The end of the spring 13 facing away from the second striking head 12 is fixedly connected to the plane of the sliding hole 111 facing away from the opening. By embedding the spring 13 into the sliding hole 111, the radial swing of the spring 13 is restricted, and the spring 13 stably plays a flexible supporting role on the second striking head 12.

[0045] In this embodiment: A plurality of first mounting ears 112 are fixedly installed on the first striking head 11, and threaded holes 1121 are provided on the plurality of first mounting ears 112;

[0046] One end of the hammer handle is fixedly connected with a plurality of second mounting ears 22 corresponding to the plurality of first mounting ears 112 one by one. A bolt 23 is rotatably fitted on the second mounting ear 22, and the threaded end of the bolt 23 is inserted into the threaded hole 1121 and connected by thread fit.

[0047] An installation hole 113 is formed on the side wall of the sliding hole 111 facing the hammer handle, and the installation hole 113 is covered by one end of the hammer handle facing the first striking head 11.

[0048] On both side walls of the opening end of the sliding hole 111 parallel to the length direction of the hammer handle, a convex strip 114 is fixedly connected. One end of the second striking head 12 facing the first striking head 11 is fixedly connected with a T-shaped block 122. By arranging an installation hole 113 on the side wall of the sliding hole 111 facing the hammer handle, it is convenient to install the spring 13 and the T-shaped block 122 into the sliding hole 111 from the installation hole 113. The convex strip 114 blocks the T-shaped block 122 to limit the T-shaped block 122 from completely sliding out of the sliding hole 111. When the spring 13 is in a natural stretching state, the T-shaped block 122 abuts against the convex strip 114, so that the T-shaped block 122 is hooked on the two convex strips 114. At the same time, the hammer handle and the first striking head 11 are detachably connected, which is convenient for overhauling and replacing each component of the hammer head. By disassembling and separating the hammer handle and the hammer head, the space occupied by the exploration hammer can be reduced, which is convenient for carrying.

[0049] In this embodiment: On one side surface of the second striking head 12 facing the installation hole 113, a plurality of limiting grooves 121 are formed, and the plurality of limiting grooves 121 are arranged in a linear array along the length direction of the hammer head.

[0050] The one-way locking assembly includes an insertion strip 24 slidably connected with the hammer handle along the length direction of the hammer handle. One end of the insertion strip 24 facing the second striking head 12 is wedge-shaped, and the inclined surface is located on the side of the opening of the sliding hole 111.

[0051] In this embodiment: The hammer handle is composed of two symmetrically arranged support strips 21 spliced together. On the opposite side surfaces of the two support strips 21, two sliding grooves 211 are formed along the length direction of the hammer handle. The two sides of the insertion strip 24 are respectively inserted into the two sliding grooves 211 and are slidably fitted.

[0052] The limiting grooves 121 are arranged on one side surface of the T-shaped block 122 facing the installation hole 113. The plurality of second mounting ears 22 are evenly distributed at both ends of the two support strips 21 facing the first striking head 11.

[0053] During use, a thrust is applied to the insert 24, causing the wedge-shaped end of the insert 24 to be inserted into the first limiting slot 121 facing the spring 13. When the second striking head 12 strikes the rock, the T-shaped block 122 slides in the sliding hole 111 towards the spring 13, and the spring 13 is compressed and contracted. The side surface of the first limiting slot 121 facing the opening of the sliding hole 111 abuts against the inclined surface of the wedge-shaped end of the insert 24, pushing the insert 24 to slide in the sliding groove 211 in the direction away from the first striking head 11. Then, the wedge-shaped end of the insert 24 slides out of the first limiting slot 121, enabling the T-shaped block to slide smoothly in the sliding hole 111. Subsequently, the wedge-shaped end of the insert 24 is sequentially inserted into the second limiting slot 121, the third limiting slot 121, and so on, until the length of the spring 13 is shortened to the shortest and the insert 24 is inserted into the last limiting slot 121.

[0054] When the pressure on the spring 13 decreases or disappears, the spring 13 freely extends to release energy, applying pressure to the T-shaped block 122 and pushing the T-shaped block 122 out of the sliding hole 111. The side surface of the last limiting slot 121 facing away from the opening of the sliding hole 111 abuts against the flat surface of the wedge-shaped end of the insert 24, applying a pressure perpendicular to the sliding direction of the insert 24 to the insert 24. As a result, the insert 24 has no power to slide in the sliding groove 211, thereby restricting the sliding of the second striking head 12 away from the first striking head 11, reducing the squeezing impact on the palm of the relevant technician, and improving the comfort of the exploration hammer.

[0055] In this embodiment: A rack 25 is provided on one side of the insert 24 facing the first striking head 11, and a gear 26 meshing with the rack 25. The rack 25 is fixedly connected to the insert 24. Both ends of the gear 26 penetrate through the side walls of the two support bars 21 and extend outside the two support bars 21, and are rotationally matched.

[0056] Both ends of the gear 26 are provided with torsion springs 27. One end of each torsion spring 27 is fixedly connected to one end of the gear 26, and the other end is fixedly connected to the corresponding support bar 21. When the torsion springs 27 are in the natural extension state, the gear 26 pushes the insert 24 into one of the limiting slots 121 through the rack 25.

[0057] During use, when the second striking head 12 strikes the rock, the T-shaped block 122 slides in the sliding hole 111 towards the spring 13, and the spring 13 is compressed and contracted. One side of the first limiting groove 121 facing the opening of the sliding hole 111 abuts against the inclined surface of the wedge-shaped end of the inserting bar 24, pushing the inserting bar 24 to slide in the sliding groove 211 in the direction away from the first striking head 11. The rack 25 on the inserting bar 24 drives the gear 26 to rotate, causing the torsion spring 27 to deform and store energy. Then, the wedge-shaped end of the inserting bar 24 slides out of the first limiting groove 121. Under the torsional force of the torsion spring 27, through the gear 26 and the rack 25, the wedge-shaped end of the inserting bar 24 is pushed to abut against the plane of the T-shaped block 122 facing the mounting hole 113. Then, during the sliding process of the T-shaped block 122, the wedge-shaped end of the inserting bar 24 is automatically inserted into the second, third,... last limiting groove 121 in sequence until the wedge-shaped end of the inserting bar 24 forms a clamping state with the last limiting groove 121, restricting the free extension of the spring 13. At the same time, the wedge-shaped end of the inserting bar 24 is inserted into the last limiting groove 121 to restrict the sliding of the second striking head 12 on the first striking head 11, making the second striking head 12 rigidly connected to the first striking head 11, so as to facilitate striking hard rocks.

[0058] When it is necessary to extend the overall length of the hammer head, manually rotate the end of the gear 26 outside the support bar 21. The torsion spring 27 deforms and stores energy. The gear 26 drives the inserting bar 24 to slide in the sliding groove 211 in the direction away from the first striking head 11 through the rack 25. Then, the wedge-shaped end of the inserting bar 24 slides out of the last limiting groove 121, so that the spring 13 extends freely, pushing the T-shaped block 122 to slide out of the opening of the sliding hole 111. Cancel the torsional force applied to the gear 26, and the torsion spring 27 extends freely to release energy, making the wedge-shaped end of the inserting bar 24 inserted into the first limiting groove 121 again, so as to facilitate the next striking operation.

[0059] In this embodiment: A dial 28 is sleeved outside the hammer handle. The dial 28 is in a U shape, and both ends of the dial 28 are fixedly connected to both ends of the gear 26 respectively.

[0060] The dial 28 is arranged on one side of the hammer handle facing the second striking head 12. When a relevant technician holds the hammer handle, just hook the dial 28 with the index finger, then the gear 26 can be driven to rotate on the support bar 21, driving the rack 25 and the inserting bar 24 to slide in the sliding groove 211 in the direction away from the first striking head 11. Then, the clamping state with the limiting groove 121 is eliminated, and the spring 13 extends freely, so as to facilitate the next striking operation. The operation is simple and convenient.

[0061] In this embodiment: At both ends of the two support bars 21 facing away from the first striking head 11, a handstop block 212 is fixedly connected respectively. The handstop block 212 is in a semi-circular disk shape.

[0062] In this embodiment: an external thread is provided on the outer circumferential surface of the handstop block 212, and a fixing cap 29 is sleeved outside the two handstop blocks 212;

[0063] An internal thread is provided on the fixing cap 29, and the fixing cap 29 is connected to the two handstop blocks 212 through threaded cooperation.

[0064] By providing the handstop block 212, when a relevant technician holds the hammer handle and swings it, the handstop block 212 blocks the palm to prevent the hammer handle from slipping out of the palm, reducing the risk of the exploration hammer falling off the palm during the swinging and hitting the rock. Anti-slip sheets 3 are adhered to the outer surfaces of the two support bars 21. The anti-slip sheets 3 are made of elastic rubber material, which improves the comfort of the palm holding and increases the friction between the hammer handle and the palm, further reducing the risk of the exploration hammer falling off the palm. The two handstop blocks 212 are fixedly installed together by the fixing cap 29 to clamp the two ends of the two support bars 21 facing away from the first striking head 11, improving the structural stability of the exploration hammer.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
