[0002] In the process of geological prospecting, adit exploration project is an important means of geological prospecting. The traditional prying tool in mines is made of solid steel, which is heavy and cumbersome. This has a significant impact on the cleaning work of loose rocks by underground construction workers, and also consumes a huge amount of time and manpower. Moreover, due to its large weight, it is easy to cause instability of the construction workers' center of gravity, and extremely easy to cause safety accidents; and with a unified length, it cannot adapt to the heights of various working faces in underground mines, sometimes being too long and sometimes too short, making it inflexible to use; this also indirectly leads to extremely inconvenient carrying and transportation.

[0003] Relatively novel prying tools have been able to achieve length adjustment. However, for the telescopic adjustment method, even after it is shortened, its weight remains unchanged. Therefore, the labor intensity of workers is still relatively high when using a shorter prying tool; and for the telescopic adjustment method, due to the limited diameter of the entire rod body, when a certain strength needs to be ensured, the wall thickness cannot be too thin, so the number of telescopic times is limited. Even when it is shortened to the shortest, it is still relatively long, resulting in inconvenient carrying and transportation. There are also some prying tools with threaded joints at the split parts. However, since the rod body will hit the rock and be vibrated during use, the threaded joints often become loose, resulting in the need to frequently tighten them, with low efficiency.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0028] Embodiment 1:

[0029] This embodiment provides a portable prying tool for mine construction, specifically as Figures 1-9 shown, which includes a connecting rod 2 and a bent flat head piece 1 and a conical piece 3 detachably installed at both ends of the connecting rod 2 through an auxiliary connecting piece 4.

[0030] The connecting rod 2 includes a handheld part and a first connecting unit 201 and a second connecting unit 203 detachably installed at the end of the handheld part through an auxiliary connecting piece 4. The handheld part is composed of a plurality of handheld units 202 detachably installed through an auxiliary connecting piece 4.

[0031] The auxiliary connecting piece 4 includes a clamping piece and a releasing piece. The clamping piece includes a clamping pin 402 and a clamping spring 404; the releasing piece includes a releasing pin 401 and a releasing spring 403. The releasing pin 401 is connected to the releasing spring 403, and the clamping pin 402 is connected to the clamping spring 404.

[0032] Male threads are provided on one end of the bent flat head piece 1, the conical piece 3, the first connecting unit 201, and one end of the handheld unit 202. Female threads are provided on the other end of the first connecting unit 201, the other end of the handheld unit 202, and both ends of the second connecting unit 203, and jacks are preset at the female threads; clamping pieces are installed at the male threads on the bent flat head piece 1, the conical piece 3, the first connecting unit 201, and the handheld unit 202, and releasing pieces are installed at the female threads on the first connecting unit 201, the handheld unit 202, and the second connecting unit 203.

[0033] The function of the conical piece 3 is to expand the rock cracks, clean the loose stones faster, and ensure the safety of underground personnel; the function of the bent flat head piece 1 is to better enter the rock cracks and use the lever principle to clean the loose stones more thoroughly.

[0034] After the unassembled parts are brought into the mine, when they are needed, first select an appropriate amount of handheld units 202 according to the actual working scene and factors such as the height of the personnel, and then press the snap-in pin 402 that is slidably connected to the male thread. At this time, the snap-in spring 404 is compressed, and then the male thread on the handheld unit 202 is screwed into the female thread on the other handheld unit 202. When the screwing is completed, the snap-in pin 402 is pushed by the snap-in spring 404 and embedded in the jack at the female thread on the handheld unit 202. At this time, due to the limiting effect of the snap-in pin 402, the two handheld units 202 cannot be rotated in the opposite direction to separate, and the handheld part is assembled. Then, through the same operation, the first connecting unit 201 and the second connecting unit 203 are screwed on the two ends of the handheld part respectively; then continue the same operation to screw the bent flat head piece 1 and the cone piece 3 on the first connecting unit 201 and the second connecting unit 203 respectively, and all assembly is completed.

[0035] When the working scene changes and the length of the handheld part needs to be changed or the bent flat head part 1 and the conical part 3 are damaged and need to be replaced, the release pin 401 is manually pressed, and the release spring 403 is compressed. At the same time, the release pin 401 pushes the locking pin 402, so that the locking pin 402 is disengaged from the socket and retracted, and the locking spring 404 is compressed. The limiting effect of the locking pin 402 is released by the release pin 401, and then the male thread and the female thread can be rotated and separated; then assembly can be carried out.

[0036] By providing the auxiliary connecting piece 4, the threaded connection between the parts is made tighter and will not be loosened due to the vibration of the stick body caused by the impact during use.

[0037] By providing a handheld portion whose length can be changed at will, it can adapt to operations in multiple scenarios and can also be adapted to workers of different heights and habits; at the same time, when the length of the handheld portion is shortened, the weight of the stick will be reduced due to the reduction in the number of handheld units 202, which can reduce the labor intensity of the personnel.

[0038] By modularizing the entire stick body, it can be convenient for carrying and transportation. At the same time, since the curved flat head piece 1 and the cone piece 3 will wear out after long-term use, it is also convenient to replace the curved flat head piece 1 and the cone piece 3.

[0039] The cone piece 3 can be directly inserted into the rock crack to quickly expand the rock crack without adjusting the angle and position of the stick body. The operation is convenient and quick, but the expansion force is slightly smaller. The curved flat head piece 1 can provide a greater force to expand the rock crack, but the angle and position of the stick body need to be adjusted to insert the rock crack, which is relatively troublesome. By setting the curved flat head piece 1 and the cone piece 3, personnel can choose according to actual conditions, which is highly practical.

[0040] Embodiment 2:

[0041] This embodiment is further extended on the basis of Embodiment 1, specifically as follows Figures 6-8 shown, the number of the clamping members and the releasing members in the auxiliary connecting member 4 is at least two each.

[0042] When using the releasing member to release the limiting effect of the clamping member, all the releasing members need to operate simultaneously to enable the male thread and the female thread to rotate and separate. That is, by setting two or more clamping members and releasing members, the probability that a person accidentally touches the release pin 401 during operation and causes the clamping pin 402 to retract can be reduced, and the stability of the limit can be improved.

[0043] As Figure 9 shown, the end of the release pin 401 away from the release spring 403 is an arc surface and is flush with the side wall of the first connection unit 201 or the hand-held unit 202 or the second connection unit 203.

[0044] By setting it flush, it can prevent the staff from being scratched by the release pin 401 during use, and further reduce the probability that a person accidentally touches the release pin 401, improving the stability of the limit.

[0045] As Figure 5 shown, the outer wall of the first connection unit 201 is provided with a first spiral groove 204. By providing the first spiral groove 204, the roughness of the hand-held part can be increased to prevent slipping when a person uses it.

[0046] As Figure 2 shown, the first connection unit 201, the hand-held unit 202, and the second connection unit 203 are all hollow. In this way, the weight of the rod body can be reduced, and the labor intensity of the personnel can be reduced.

[0047] Embodiment 3:

[0048] This embodiment is further extended on the basis of Embodiment 2, specifically as follows Figure 5 shown, the outer wall of the first connection unit 201 is provided with a second spiral groove 205, and the second spiral groove 205 has a spiral direction opposite to that of the first spiral groove 204. By providing the second spiral groove 205 to cooperate with the first spiral groove 204, the anti-slip effect can be further improved.

[0049] Embodiment 4:

[0050] This embodiment is further extended on the basis of Embodiment 1. The outer side of the first connection unit 201 is covered with an anti-slip pad to prevent slipping when a person uses it. The material of the anti-slip pad is one of silicone, rubber, plastic, leather, and cloth.

[0051] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
