[0022] The following is combined with Figure 1-Figure 5 The specific implementation modes of the present utility model are further described in detail.

[0023] Depend on Figure 1-Figure 5 The utility model includes a support rod 1. In order to enable the device to be stably fixed on different grounds, an indicator sign 2 is fixedly connected to the upper side of the support rod 1. A rotatable conical head 3 is provided on the lower side of the support rod 1. A fixing thread 4 is provided on the outer side of the conical head 3. A power rod 5 that can move up and down is provided inside the conical head 3. A plurality of first connecting rods 6 are rotatably connected to the middle part of the power rod 5. A second connecting rod 7 rotatably connected to the power rod 5 is provided on the lower side of each first connecting rod 6. The middle part of the conical head 3 is provided with a plurality of first connecting rods 6. The second connecting rod 7 rotatably connected to the power rod 5 is provided on the lower side of each first connecting rod 6. A movable support plate 8 corresponding to the first connecting rod 6 is provided, and the support plate 8 cooperates with the fixed thread 4 and the conical head 3 to form a structure supported by the device. The power rod 5, the first connecting rod 6, the second connecting rod 7 and the support rod 1 cooperate with each other to form a quadrilateral mechanism, wherein there is a limit between the first connecting rod 6 and the conical head 3, so that when the power rod 5 is lowered, the support plate 8 can be moved outward for support. The fixed thread 4 is divided into multiple parts, which are respectively fixedly connected to the conical head 3 and the corresponding support plate 8, and the middle part of the support rod 1 is fixedly connected to two fixed handles 9;

[0024] When in use, the device can be moved to a suitable position, and then the fixed handle 9 is held tightly with both hands to rotate the conical head 3, and then the conical head 3 can be drilled into the ground under the action of the fixed thread 4. After the conical head 3 rotates a certain number of times, the power rod 5 will move downward, and then the support rod 1 will move relative to the conical head 3 under the action of the first connecting rod 6 and the second connecting rod 7, and the stability of the conical head 3 is increased by the support plate 8.

[0025] Further, by Figure 1 , Figure 2 and Figure 4 In order to achieve a better effect, a guide block 10 is slidably connected to the middle of each first connecting rod 6, and each guide block 10 is rotatably connected to the conical head 3. A hole adapted to the first connecting rod 6 is opened in the middle of the guide block 10. The first connecting rod 6 is plugged into the corresponding guide block 10. A power threaded rod 11 is rotatably connected to the upper side of the power rod 5, and the power threaded rod 11 is threadedly connected to the conical head 3.

[0026] When in use, the power threaded rod 11 will descend when it rotates, thereby driving the power rod 5 to descend.

[0027] Further, by Figure 2-Figure 5 It is given that a first relay rod 12 is inserted into the upper side of the power threaded rod 11, and a second relay rod 13 is fixedly connected to the upper side of the first relay rod 12. A rotatable third relay rod 14 is provided inside the support rod 1, and a connecting sleeve 15 is slidably sleeved on the outer side of the third relay rod 14. The connecting sleeve 15 is inserted into the third relay rod 14 and cannot rotate relatively. A plurality of second key grooves 16 that can be adapted to the second relay rod 13 are provided inside the connecting sleeve 15. The outer side of the second relay rod 13 is fixedly connected to the spline, and the lower end of the second key groove 16 is provided with a chamfer, which can be conveniently adapted to the spline on the second relay rod 13, and the connecting sleeve 15 is threadedly connected to the support rod 1;

[0028] When in use, the third relay rod 14 will rotate, and then the connecting sleeve 15 will move downward and rotate at the same time under the action of the threaded connection between the connecting sleeve 15 and the support rod 1. When the third relay rod 14 rotates a certain number of circles, that is, after the connecting sleeve 15 moves downward to a certain height, the connecting sleeve 15 will cooperate with the second relay rod 13, so that the second relay rod 13 drives the first relay rod 12 to rotate, and then drives the power threaded rod 11 to rotate.

[0029] Further, by Figure 2-Figure 5It is given that, in order to enable the device to be automatically unfolded and supported with one button, a connecting ring 17 is fixedly connected to the upper side of the conical head 3, and the conical head 3 is rotatably connected to the support rod 1 through the connecting ring 17. An outer gear ring 18 is fixedly connected to the inside of the support rod 1, and a plurality of planetary gears 19 are meshed on the inner side of the outer gear ring 18. The planetary gears 19 are meshed with a sun gear 20 rotatably connected to the support rod 1 on the side away from the outer gear ring 18. A planet carrier 21 rotatably connected to the support rod 1 is provided on the lower side of the outer gear ring 18. The planet carrier 21 is used to improve the stability of the planetary gears 19 and the planetary rods 22 during rotation. A plurality of planetary rods 22 corresponding to the planetary gears 19 are fixedly connected to the middle part of the planet carrier 21. Each of the planetary gears 19 is rotatably connected to the planet carrier 21 through the planetary rods 22. A connecting hole 23 corresponding to the planetary rods 22 is opened in the middle part of the connecting ring 17. The planetary rods 22 and the connecting holes 23 cooperate with each other to form a structure in which the conical head 3 can rotate with the planetary carrier 21.

[0030] When in use, the sun gear 20 will rotate, and then the planetary gear 19 will drive the planetary carrier 21 to rotate through the planetary rod 22 under the joint action of the outer ring gear 18 and the sun gear. When the planetary rod 22 rotates, it will drive the connecting ring 17 to rotate through the connecting hole 23, thereby rotating the conical head 3.

[0031] Further, by Figure 2-Figure 5 It is given that, in order to enable the device to operate automatically, a rotating rod 24 is fixedly connected to the upper side of the third relay rod 14, the middle part of the rotating rod 24 is fixedly connected to the sun gear 20, and a motor 25 is fixedly connected to the upper side of the rotating rod 24. The motor 25 is a servo motor 25, which is a prior art and will not be described in detail here. When the device needs to be retracted, the motor 25 can be reversed to remove the device from the ground fixed state;

[0032] When in use, the motor 25 drives the sun gear 20 and the third relay rod 14 to rotate through the rotating rod 24, so that the device can operate.

[0033] Further, by Figure 2-Figure 5 It is given that, in order to increase the protection performance of the device, a protection frame 26 is fixedly connected to the outer side of the sign 2;

[0034] When in use, the protective frame 26 can be used to protect the mine from falling objects such as tiny rocks and rainfall. The sign 2 is made of magnetic material and can absorb appropriate warning signs.

[0035] When the utility model is used, the device can be first moved to a suitable position, and then the fixed handle 9 is held tightly with both hands and pressed toward the ground. After the motor 25 is started, the motor 25 drives the sun gear 20 to rotate through the rotating rod 24, and then the planetary gear 19 drives the planetary carrier 21 to rotate through the planetary rod 22 under the joint action of the outer gear ring 18 and the sun gear. When the planetary rod 22 rotates, the connecting ring 17 is driven to rotate through the connecting hole 23, so that the conical head 3 is rotated, and the conical head 3 can be drilled into the ground under the action of the fixed thread 4. At the same time, the rotating rod 24 will also drive the third relay rod 14 to rotate. Under the action of the threaded connection between the connecting sleeve 15 and the support rod 1, the third relay rod 14 drives the connecting sleeve 15 to rotate. The sleeve 15 rotates while moving downward. When the third relay rod 14 rotates a certain number of times, that is, the connecting sleeve 15 moves downward to a certain height, the connecting sleeve 15 will cooperate with the second relay rod 13, so that the second relay rod 13 drives the first relay rod 12 to rotate, and then drives the power threaded rod 11 to rotate. Due to the threaded connection between the power threaded rod 11 and the conical head 3, the power threaded rod 11 will descend when rotating, and then drive the power rod 5 to descend, and then under the action of the first connecting rod 6 and the second connecting rod 7, the support rod 1 is moved relative to the conical head 3, and the stability of the conical head 3 is increased by the support plate 8. At this time, the device is fixed, and the protective frame 26 can be used to protect the mine from tiny falling rocks, rainfall and other falling objects.

[0036] The utility model has a novel structure, ingenious conception, and simple and convenient operation. Through the design, the purpose of enabling the device to be stably fixed on different grounds is effectively achieved, the device can be automatically unfolded and supported with one button, the device can be automatically operated, and the operation of the staff is convenient, which increases the protection performance of the device.
