[0062] The accommodating groove 301 is disposed at one end of the long rod 202 adjacent to the clamping block 203a.

[0063] Specifically, the receiving groove 301 and the first opening 302 are interconnected.

[0064] Furthermore, the reset portion 303 includes a first ring 303 a disposed inside the receiving groove 301 , and a first spring 303 b disposed on the first ring 303 a .

[0065] The outer wall of the first ring 303 a contacts the inner wall of the receiving groove 301 .

[0066] The top of the first ring 303a is connected to the bottom of the first spring 303b.

[0067] Furthermore, the extrusion portion 304 includes a second ring 304a disposed on the first spring 303b, a second spring 304b and a limiting rod 304c disposed on the second ring 304a, a limiting block 304d disposed on the limiting rod 304c, and a third ring 304e disposed on the second spring 304b.

[0068] The top of the first spring 303b is connected to the bottom of the second ring 304a.

[0069] The top of the second ring 304a is connected to the bottom of the second spring 304b.

[0070] A limiting rod 304c is installed on one side of the second circular ring 304a adjacent to the first circular ring 303a.

[0071] One end of the limiting rod 304c away from the second circular ring 304a penetrates the first circular ring 303a and is connected to the limiting block 304d.

[0072] Specifically, the limiting block 304d can prevent the limiting rod 304c from being separated from the first ring 303a.

[0073] Specifically, the limiting rod 304c can make the movement of the second ring 304a more stable.

[0074] Specifically, there are multiple limiting rods 304c, and the multiple limiting ring rods are evenly distributed on the second ring 304a.

[0075] The top of the second spring 304b is connected to the bottom of the third ring 304e.

[0076] Specifically, the third ring 304e is fixedly connected to the inner wall of the accommodating groove 301 .

[0077] Specifically, the inner diameter of the first circular ring 303a, the inner diameter of the second circular ring 304a and the inner diameter of the third circular ring 304e are all the same.

[0078] Specifically, when the second circular ring 304a is squeezed by the squeezing block 105d, the second circular ring 304a drives the second spring 304b to extend, and at the same time, the second circular ring 304a drives the first spring 303b to descend, and the first spring 303b drives the first circular ring 303a to descend.

[0079] Furthermore, the sealing portion 305 includes a spherical groove 305a disposed on the long rod 202, a sphere 305b disposed inside the spherical groove 305a, and an arc groove 305c disposed on the sphere 305b.

[0083] The arc groove 305c is arranged on the outer side wall of the sphere 305b.

[0084] Specifically, the arc groove 305c is located outside the long rod 202. When the staff member moves the ball 305b, the friction between the ball 305b and the hand is increased, so that the ball 305b can be moved more conveniently.

[0085] Furthermore, the rotating portion 306 includes a groove 306a disposed on the long rod 202, and a rotating rod 306b and a third spring 306c disposed on the sphere 305b.

[0086] The groove 306a and the spherical groove 305a are interconnected.

[0087] Specifically, there are two grooves 306a, and the two grooves 306a are respectively located on both sides of the spherical groove 305a.

[0088] Two rotating rods 306b are installed on the side wall of the sphere 305b, and one end of the rotating rod 306b away from the sphere 305b is rotatably connected to the inner wall of the groove 306a.

[0089] Specifically, by providing the two rotating rods 306b, the rotation direction of the ball 305b can be restricted so that the ball 305b can only rotate forward and reverse in one direction.

[0090] Two third springs 306c are installed on the side wall of the sphere 305b, and one end of the third spring 306c away from the sphere 305b is connected to the inner wall of the groove 306a.

[0091] Specifically, the third spring 306c is sleeved on the periphery of the rotating rod 306b.

[0092] Specifically, when the sphere 305b rotates, the sphere 305b can drive the third spring 306c to rotate and contract. When the sphere 305b loses its restriction, the third spring 306c drives the sphere 305b to return to its initial state.

[0093] Furthermore, the plug-in portion 307 includes a through hole 307a and a slot 307b disposed on the sphere 305b, an insert rod 307c disposed on the first ring 303a, and a second through hole 307d disposed on the long rod 202.

[0094] The diameter of the through opening 307 a is the same as the diameter of the first through opening 302 .

[0095] Specifically, when the first through opening 302 is directly opposite to the through opening 307 a , the detonator can be moved from the inside of the long rod 202 to the outside of the long rod 202 .

[0096] The slot 307b is disposed on the side wall of the sphere 305b.

[0097] One end of the first ring 303a away from the second ring 304a is connected to the insertion rod 307c.

[0098] Specifically, the end of the rod 307c away from the first ring 303a is inserted into the interior of the slot 307b through the second opening 307d. At this time, the position of the ball 305b is restricted and the ball 305b cannot rotate. At this time, the through opening 307a and the first opening 302 are not interconnected, and the ball 305b seals the first opening 302.

[0099] Operation process: To prevent the soil inside the hole from easily sealing the hole again during the process of pulling out the long rod 202 from the soil, which may affect the staff's insertion of the detonator to the bottom of the hole and the blasting effect. When the staff inserts the long rod 202 into the inside of the threaded ring 105c, the extrusion block 105d will extrude the second ring 304a, causing the second spring 304b to be compressed and contract. The second spring 304b then squeezes the first ring 303a, making the first spring 303b contract. The first ring 303a drives the insertion rod 307c to contact the side wall of the sphere 305b. At this time, when the staff turns the sphere 305b, the sphere 305b rotates. The sphere 305b drives the rotating rod 306b and the third spring 306c to rotate together, and the third spring 306c rotates and contracts. After the sphere 305b rotates 90°, when the insertion rod 307c moves to the slot 307b, the first spring 303b resumes its expansion and drives the first ring 303a. The first ring 303a drives the insertion rod 307c to insert into the inside of the slot 307b. At this time, the position of the sphere 305b is restricted, and the sphere 305b seals the bottom end of the long tube. When the staff starts the motor 105b to drill the soil, after the hole is drilled, to prevent the soil from sealing the hole again during the process of pulling out the long rod 202, the staff rotates the threaded sleeve 203b to separate the motor 105b from the long rod 202. At this time, the extrusion block 105d removes the extrusion on the second ring 304a, and the second spring 304b resumes its expansion and drives the second ring 304a to rise. The second ring 304a drives the first spring 303b, and the first spring 303b drives the first ring 303a to rise. The first ring 303a drives the insertion rod 307c to disengage from the inside of the slot 307b. Since the sphere 305b loses its restriction, the third spring 306c resumes its expansion and drives the sphere 305b to rotate. The sphere 305b drives the rotating rod 306b to rotate. When the third spring 306c returns to its initial position, the through-hole 307a on the sphere 305b communicates with the through-port. At this time, the staff can insert the detonator into the inside of the accommodating groove 301. The detonator enters the inside of the through-port from the third ring 304e, the second ring 304a, and the first ring 303a. The detonator slides downward from the through-port into the inside of the through-hole 307a, and the bottom of the detonator contacts the bottom of the hole. At this time, the staff pulls the long rod 202 upward, and the long rod 202 disengages from the soil. The detonator stays at the bottom of the hole, reaching the designated position of the staff, ensuring the accuracy of the blasting.

[0100] When the staff needs to prepare for the next hole drilling and blasting, the staff only needs to complete the docking of the long rod 202 with the motor 105b.
