[0024] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the cutter head mechanism 2 includes a cutter head body 201, a cutter head body 201 is provided at the bottom of the handle 1, the cutter head body 201 is a conical structure, a cutter core column 204 is welded at the top center of the cutter head body 201, the cutter core column 204 is a rectangular parallelepiped structure, a plurality of stacked blades 202 are provided at the top of the cutter head body 201, and the plurality of blades 202 are respectively slidably connected to the cutter core column 204, a slot 205 is provided at the bottom center of the handle 1, the top of the cutter core column 204 extends to the inside of the slot 205, and the bottom of the handle 1 is connected to a cutter at the top. The blade 202 interferes with the cutter head body 201, and the installation of the blade core column 204 and the cutter head body 201 facilitates the connection between the blade core column 204 and the cutter handle 1, thereby realizing the installation of the cutter head body 201, and thus performing hole expansion drilling. The design of the conical structure of the cutter head body 201 can achieve a better drilling effect.

[0026] Specifically, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the limiting mechanism 3 includes a clamping strip 302, and the handle 1 is internally installed with symmetrically distributed toothed clamping strips 302, and the opposite sides of the two clamping strips 302 extend to the inner side of the slot 205, and the inner side of the top of the knife core column 204 is installed with a symmetrical clamping block 301, and the clamping block 301 is slidably connected with the inside of the knife core column 204 through a resisting spring 303, and one end of the two clamping blocks 301 respectively extends to the outer side of the knife core column 204 and engages with the two clamping strips 302. Through the installation of the two clamping strips 302, after the knife core column 204 is inserted into the slot 205, the clamping block 301 and the clamping block The knife core column 204 is in contact with the strip 302, and the block 301 has elasticity under the action of the contact spring 303.

With the cooperation of the telescopic spring 304, the pressure block 305 can slide inside the slot 205, and under the elastic force of the telescopic spring 304, the pressure block 305 always keeps in contact with the knife core column 204, so that the block 301 on the knife core column 204 is stably engaged with the card strip 302, but will not be contracted by the conflict, which is conducive to the looseness between the block 301 and the card strip 302 without gap, so that the knife core column 204 and the knife handle 1 are stably connected.

[0028] Specifically, Figure 3 and Fig. 9As shown, a plurality of rubber blocks 306 distributed in an annular shape are installed on the inner side of the bottom of the knife handle 1. The rubber block 306 is a "convex" shaped structure. An extrusion spring 307 is connected between one end of the plurality of rubber blocks 306 and the inside of the knife handle 1. The rubber block 306 is slidably connected to the inside of the knife handle 1 through the extrusion spring 307. The bottoms of the plurality of rubber blocks 306 extend to the outside of the knife handle 1 and contact the top side of the blade 202. Through the installation of the plurality of rubber blocks 306, after the knife handle 1 is stably connected to the knife core column 204, the bottoms of the plurality of rubber blocks 306 contact the top side of the blade 202, so that the plurality of stacked blades 202 are tightly contacted, which is convenient for subsequent stable drilling work. At the same time, with the cooperation of the extrusion spring 307, the rubber block 306 has elasticity, so that the rubber block 306 always keeps contacting with the blade 202, making the contact of the blade 202 more stable.

[0029] Specifically, Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the locking mechanism 4 includes a pull rod 402, and the pull rod 402 is installed at the inner center of the cutter head body 201. The top of the pull rod 402 extends to the inner center of the knife core column 204, and the bottom of the pull rod 402 extends to the outside of the bottom of the cutter head body 201. A reset spring 403 is installed at the inner center of the cutter head body 201. The pull rod 402 is slidably connected with the cutter head body 201 and the inner part of the knife core column 204 through the reset spring 403. A through groove 404 is provided on the top of the pull rod 402. Guide rods 405 are respectively vertically connected at the centers of the opposite ends of the two blocks 301. One ends of the two guide rods 405 respectively penetrate the resistance spring 303 and extend to the side wall of the pull rod 402. The two guide rods 405 are located at the bottom of the through groove 404. Through the cooperation of the reset spring 403, the pull rod 402 is located at the center of the tool head body 201 and the tool core column 204. Through the interference between the two guide rods 405 and the side walls of the pull rod 402, the two blocks 301 cannot slide freely, thereby making the tool core column 204 and the tool handle 1 stably connected and not separated. By pulling the pull rod 402, the pull rod 402 gets rid of the elastic force of the reset spring 403 and slides down, and the through groove 404 on the pull rod 402 slides to one end of the two guide rods 405, so that the guide rod 405 can be accurately inserted into the two ends of the through groove 404, so that the block 301 can be driven by external force to shrink, which is convenient for disassembly and assembly of the tool core column 204 and the tool handle 1.

The lubricating oil enters the oil storage tank 501 through the conveying groove 502 and is stored in a small amount. The cooperation of the oil guide groove 503 allows the lubricating oil to overflow the outside of the pull rod 402 to lubricate the sliding of the pull rod 402. The lubricating oil enters the through groove 404 through the conveying groove 502, which facilitates the lubrication of the guide rod 405.

The opening of the mounting groove 603 facilitates the insertion and installation of the detector 602. Through the installation of the rubber sleeve 601, the detector 602 is stably installed in the mounting groove 603 and will not slip out, and the rubber sleeve 601 contacts and seals the inner side of the mounting groove 603 to play a waterproof role. Through the installation of the detector 602 and the cutter head body 201, real-time monitoring of underground harmful gases and rock formation conditions is achieved.

[0032] Specifically, Fig.10As shown, the engaging mechanism 7 includes a slot 701, and the side wall of the pull rod 402 is provided with a symmetrically distributed slot 701, the slot 701 is a notch-shaped structure, the diameter of one end of the slot 701 is larger than the diameter of the other end, the two slots 701 are located on one side of the two mounting slots 603, the opposite ends of the mounting slots 603 extend to one side of the pull rod 402, the opposite ends of the two detectors 602 are vertically connected to the limiting rod 702, the limiting rod 702 is a cylindrical "T"-shaped structure, the diameter of one end of the limiting rod 702 is smaller than the diameter of one end of the slot 701, the two limiting rods 702 extend to the inside of the two slots 701 and engage with each other, and are opened through the slots 701. When the detector 602 is installed, the pull rod 402 is pulled in advance, and the pull rod 402 drives the slot 701 to slide to a certain position. After the two detectors 602 are inserted into the installation slot 603, the limit rods 702 on the two detectors 602 are respectively inserted into the inner side of one end of the two slots 701. Then the external force is removed, the pull rod 402 is reset, and the slot 701 slides upward, so that the limit rod 702 is located at the other end of the slot 701. The outer diameter of the other end of the slot 701 is smaller than the diameter of one end, so that the limit rod 702 cannot slide out, which plays a limiting role, so that the detector 602 can be installed stably and will not slip off.

[0033] Specifically, Fig.11 As shown, rubber rings 703 are slidably connected inside the two installation grooves 603, and a compression spring 704 is connected between one side of the rubber ring 703 and the inner side of the installation groove 603.

Through the cooperation of the compression spring 704, the rubber ring 703 has elasticity, so that the rubber ring 703 always keeps in contact with the detector 602, so that the detector 602 is stably installed and will not loosen, and the detector 602 is easy to pop out for maintenance after the limit is released later.

[0034] When the present invention is in use, firstly, the installation of the blade core column 204 and the cutter head body 201 is facilitated to connect the blade core column 204 and the cutter handle 1, so as to realize the installation of the cutter head body 201, thereby carrying out hole expansion drilling. The design of the tapered structure of the cutter head body 201 makes the drilling effect better. The installation of multiple stacked blades 202 and the cutter head body 201 realizes the increase of the diameter of the cutter head body 201. By installing blades 202 of different diameters, it is convenient to drill holes of different sizes according to needs, and the operation is more convenient and efficient. The opening of the chip guide groove 203 plays a role in diverting water and sand and gravel, which is conducive to the smooth drilling of the cutter head body 201 and the multiple stacked blades 202, and will not cause the phenomenon of mud and sand blocking and unable to be discharged. Through the installation of the two clamping strips 302, after the knife core column 204 is inserted into the slot 205, the clamping block 301 conflicts with the clamping strip 302, and the clamping block 301 has elasticity under the action of the conflicting spring 303. By a certain force against the knife core column 204, the clamping block 301 will be compressed by the clamping strip 302 to facilitate the sliding of the knife core column 204. According to the amount of installed blade 202, the depth of the knife core column 204 inserted into the handle 1 is different. After the knife core column 204 is inserted into the handle 1, the clamping block 301 always keeps in conflict with the clamping strip 302 under the elastic force of the conflicting spring 303, and the knife core column 204 is stably connected to the handle 1.

After the connection between the handle 1 and the knife core column 204 is stable, the bottom of the multiple rubber blocks 306 is in contact with the top side of the blade 202, so that the multiple stacked blades 202 are tightly in contact, which is convenient for subsequent stable drilling work. At the same time, with the cooperation of the extrusion spring 307, the rubber block 306 has elasticity, so that the rubber block 306 always keeps in contact with the blade 202, making the contact of the blade 202 more stable. The cooperation of the positioning spring 403 makes the pull rod 402 located at the center of the cutter head body 201 and the knife core column 204. The two guide rods 405 are in contact with the side wall of the pull rod 402, so that the two blocks 301 cannot slide freely, so that the knife core column 204 and the knife handle 1 are stably connected and will not separate. By pulling the pull rod 402, the pull rod 402 is freed from the elastic force of the reset spring 403 and slides down, and the through groove 404 on the pull rod 402 slides to one end of the two guide rods 405, so that the guide rod 405 can be accurately inserted into the two ends of the through groove 404, so that the block 301 can be driven by external force to shrink, which is convenient for disassembly and assembly of the knife core column 204 and the knife handle 1, and is conducive to the cooperation of the pull rod 402 and the reset spring 403 in the cutter head body 201 and the knife core column 204. Telescopic sliding,The guide rod 405 can be accurately inserted into the through groove 404 to realize the movement of the block 301. The installation of the leather plug 504 is conducive to blocking the bottom of the conveying groove 502, and it is convenient to add lubricating oil to the conveying groove 502 after the leather plug 504 is removed later. The lubricating oil enters the oil storage tank 501 through the conveying groove 502 and is stored in a small amount. The cooperation of the oil guide groove 503 allows the lubricating oil to overflow the outside of the pull rod 402 to lubricate the sliding of the pull rod 402. The lubricating oil enters the through groove 404 through the conveying groove 502, which is conducive to lubricating the guide rod 405. The opening of the installation groove 603 is conducive to the insertion and installation of the detector 602. The installation of the rubber sleeve 601 makes the detector 602 and the installation groove 603 stably installed and will not slip out. The rubber sleeve 601 contacts and seals the inner side of the installation groove 603 to play a waterproof role. The installation of the detector 602 and the cutter head body 201 can realize real-time monitoring of underground harmful gases and rock formation conditions. The slot 701 is opened. When installing the detector 602, the pull rod 402 is pulled in advance, and the pull rod 402 drives the slot 701 to slide to a certain position. After the two detectors 602 are inserted into the installation slot 603, the limit rods 702 on the two detectors 602 are respectively inserted into the inner side of one end of the two slots 701. Then the external force is removed, the pull rod 402 is reset, and the slot 701 slides upward, so that the limit rod 702 is located at the other end of the slot 701. The outer diameter of the other end of the slot 701 is smaller than the diameter of one end, so that the limit rod 702 cannot slide out, which plays a limiting role, so that the detector 602 is stably installed and will not slip off. Through the installation of the rubber ring 703, the detector 602 will not be squeezed and damaged after installation. Through the cooperation of the compression spring 704, the rubber ring 703 has elasticity, so that the rubber ring 703 always keeps in contact with the detector 602, so that the detector 602 is stably installed and will not loosen, and after the limit is released later, the detector 602 is easy to pop out for maintenance.
