Technical Field
[0001] The invention belongs to the technical field of assembled house construction, and in particular relates to a wall drilling device for assembled house construction. Background Art
[0002] Prefabricated houses refer to the use of industrialized production methods to build houses, that is, the stairs, exterior walls, balconies, air conditioning panels, etc. of the house are prefabricated in factories outside the construction site using assembly lines, and then transported to the construction site for "assembly", and the interior of the house will be finely decorated at one time before being put into use. That is, the huge exterior walls, stairs, and balconies from the factory are "assembled" into houses and buildings on the construction site. Prefabricated houses are built quickly and almost no dust is generated on site. In recent years, the labor cost of the domestic construction industry has become increasingly high, and the huge amount of construction waste and haze generated by traditional construction projects have seriously affected the environment. Therefore, the traditional construction model is in urgent need of change, and prefabricated houses are gradually taking the path of factory production. Prefabricated houses also include prefabricated concrete prefabricated houses, and the walls need to be drilled during the assembly of prefabricated houses.
[0003] The prior art has the following disadvantages when drilling holes in walls: 1. When using a traditional drilling machine, there is a situation where the drilled hole may not be horizontal enough and cannot be used or the use effect is poor. The required drilled hole should be perpendicular to the wall surface so that the subsequent installation depth can be stabilized through the drilling depth. However, the horizontal drilling requires skilled personnel to operate carefully, which reduces the drilling efficiency; 2. When drilling holes in the wall, the drilling depth is often not enough and needs to be re-drilled. If the drilling depth is too deep, it is easy to cause unnecessary damage to the stability of the wall. Therefore, when drilling holes in the wall, the drilling depth is a matter that requires skilled and cautious operation, which will bring inconvenience to the operator. Summary of the invention
[0004] The purpose of the present invention is to provide a wall drilling device for assembled house construction, which has the advantages of improving drilling stability, increasing the horizontality of the drilled hole, ensuring the verticality of the hole and the wall, and the user can relax the support force on the handle, reducing the arm discomfort caused by the weight of the drilling device during use. By ensuring the horizontality of the hole, the stability of subsequent installation can be effectively guaranteed, and the hidden danger of installation stability caused by insufficient drilling depth of inclined holes can be avoided; it is convenient to flexibly change the depth of the hole required by the drill bit, increase the intuitiveness of the drilling depth, and make drilling more convenient to use.
[0005] The above technical purpose of the present invention is achieved through the following technical solutions: a wall drilling device for assembled house construction, including a drilling mechanism, the drilling mechanism including a shell, a handle fixedly installed on the bottom of the shell, a stabilizing mechanism provided on the top of the handle, the stabilizing mechanism including a stabilizing component, a ventilation component and a transmission component, the stabilizing component including a right bottom shell, a left bottom shell, a right top shell and a left top shell, the ventilation component including an inner shell, the transmission component including a bevel gear 1, an adjustment mechanism is provided on one side of the handle, the adjustment mechanism including a moving component and an adjustment component, the moving component including a vertical plate, and the adjustment component including rotating rod 1, rotating rod 2, rotating rod 3 and rotating rod 4.
[0006] By adopting the above technical scheme, when using the wall drilling device for assembled house construction, the position of the suction cup is adjusted first, so that when the suction cup contacts the wall, one end of the drill bit does not contact the wall. Then the rotary motor is operated, so that the operation of the rotary motor drives the drill bit to idle, and the rotary motor drives the transmission component to operate, so that the ventilation component drives the stabilizing component to achieve stable adsorption and fixation of the suction cup and the wall. At the same time, the operator adjusts the length of the ventilation pipe through the adjustment mechanism. After adjusting the ventilation pipe toward the user, the suction cup is always adsorbed and fixed to the wall, and the rotating drill bit will gradually advance into the wall, and the stable drilling use of the drilling device is achieved at this time. This setting is conducive to improving the drilling stability, increasing the horizontality of the drilled hole, and ensuring the verticality of the hole and the wall. The user can relax the support force on the grip, reduce the user's arm discomfort caused by the weight of the drilling device during use, and by ensuring the horizontality of the hole, the stability of the subsequent installation can be effectively guaranteed, avoiding the hidden danger of installation stability caused by insufficient drilling depth of the inclined hole. At the same time, in the use of the wall drilling device for assembled house construction, the use of the adjustment mechanism will facilitate the adjustment of the drilling depth. By adjusting the lengths of the four ventilation pipes inside the right bottom shell, the left bottom shell, the right top shell and the left top shell, the drilling depth of the drill bit can be observed in conjunction with the scale. When the operator needs to use the drill bit to drill, the adjustment component will drive the moving component to achieve it. When the inner pull part is pulled inward, the ventilation pipe will be progressively moved to the inside of the right bottom shell, the left bottom shell, the right top shell and the left top shell, and when the outer push part is pushed outward, the ventilation pipe will move to the outside of the right bottom shell, the left bottom shell, the right top shell and the left top shell, so as to flexibly change the required drilling depth of the drill bit. This setting distinguishes the inconvenience of obtaining the drilling depth based on the skilled experience of the drilling master, increases the intuitiveness of the drilling depth, and makes drilling more convenient to use.
[0007] The present invention is further configured as follows: a rotating motor is provided inside the shell, a fixing ring fixedly connected to the inside of the shell is fixedly sleeved on the surface of the rotating motor, a driving rod is fixedly sleeved on the output end of the rotating motor via a coupling, a mounting block is fixedly installed on one end of the driving rod, a drill bit penetrating to the outside of the shell is connected to the internal thread of the mounting block, and a ring 1 fixedly connected to the inside of the shell is rotatably sleeved on the surface of the mounting block via a bearing.

The rotation of the driving rod will drive the mounting block to rotate, and the mounting block is fastened to the drill bit through a threaded connection. However, when the drill bit follows the rotation of the mounting block, the rotation trend is opposite to the thread direction, so the drill bit will not slip during operation, and the threaded connection will ensure the convenience of installation and disassembly of the drill bit. The first collar will realize the smooth rotation of the mounting block inside the housing through the bearing.
[0009] The present invention is further configured as follows: a connecting shell is fixedly connected between the right bottom shell and the left bottom shell, a connecting piece is fixedly connected between the right bottom shell and the right top shell and the left bottom shell and the left top shell, the inside of the right bottom shell, the left bottom shell, the right top shell and the left top shell are all provided with a ventilation pipe that passes through to the outside, the surface of the ventilation pipe is connected to a connecting pipe, and one end of the ventilation pipe is connected to a suction cup.
[0010] With the above technical solution, the connecting shell is used in conjunction with the right bottom shell and the left bottom shell, and the connecting piece is used in conjunction with the right bottom shell and the right top shell and the left top shell and the left top shell. When the suction cup contacts the wall, the air between the suction cup and the wall is extracted and transferred through the vent pipe.
[0011] The present invention is further configured as follows: the inner shell is located inside the shell, the inner side of the inner shell is slidably connected to a piston, one side of the piston is provided with a partition fixedly connected to the inner side of the inner shell, a one-way valve is embedded in the partition, both ends of the two sides of the inner shell are fixedly installed with fixing blocks fixedly connected to the inner side of the shell, both sides of the inner shell are connected with pipes that run through the outside of the shell, one end of the pipe is connected with a three-way pipe, both ends of the two three-way pipes are connected with bellows, one end of the bellows is connected to the connecting pipe, and fixing parts are fixedly installed on the surfaces of the four bellows, and the four fixing parts are respectively fixedly connected to the right bottom shell, the left bottom shell, the right top shell and the left top shell, and a one-way valve is embedded in the top of the inner shell.
[0012] With the above technical solution, the sliding of the piston will adjust and change with the air inside the inner shell, and the partition will divide the inner shell into two parts. The one-way valve 1 will cooperate with the gas on the other side of the partition to only go out but not in, and the fixed block will cooperate with the inner shell to support and fix. Among them, the one-way valve 2 will cooperate with the gas inside the inner shell and on one side of the partition to only go out but not in, and the bellows will transfer the gas inside the ventilation pipe through the connecting pipe, and then the gas will come to the inner shell through the tee pipe and the pipeline.
[0013] The present invention is further configured as follows: the bevel gear 1 and the driving rod are fixedly sleeved with each other, the surface of the bevel gear 1 is meshed with the bevel gear 2, the inside of the bevel gear 2 is fixedly sleeved with a rod body, the surface of the rod body is rotatably sleeved with a support plate fixedly connected to the inside of the shell through a bearing, the top of the rod body surface is fixedly sleeved with a connecting plate, the top of one end of the connecting plate is fixedly installed with a guide block, the surface of the guide block is slidably sleeved with a guide ring, and one side of the guide ring is fixedly installed with a connecting plate that penetrates into the inner shell and is fixedly connected to the piston.
[0014] With the above technical solution, the rotation of the driving rod will drive the bevel gear 1 to rotate, the rotation of the bevel gear 1 will drive the bevel gear 2 to rotate, and the bevel gear 2 will synchronously drive the rod body to rotate, wherein the support plate will support the rod body and smoothly rotate with the rod body through the bearing. The rotation of the rod body will drive the connecting plate to move, and the connecting plate will drive the guide block at one end to realize the running trend around the rod body as the center of the circle, so that the guide block drives the guide ring to reciprocate, and the guide ring drives the connecting plate and the piston to move synchronously.

[0016] By adopting the above technical solution, the air inlet can achieve gas balance inside the inner shell by letting air into the inner shell when the suction cup needs to be removed. When the air inlet needs to be let in air, the operator pinches the pinching block so that the pinching block drives the inner rod and the plug to move longitudinally. After the plug is separated from the inside of the air inlet, the air inlet can be let in. The spring 1 will be contracted by the movement of the plug. In the initial state, the extension state of the spring 1 ensures the sealing effect of the plug on the air inlet.
[0017] The present invention is further configured as follows: the number of the vertical plates is four and they are respectively located on the inner sides of the right bottom shell, the left bottom shell, the right top shell and the left top shell; the top and bottom of one side of the vertical plate are respectively fixedly installed with a horizontal plate and a rack; the top of the rack is meshed with a meshing gear; the top and bottom of the horizontal plate and the rack are both fixedly installed with a clamping strip; the insides of the right bottom shell, the left bottom shell, the right top shell and the left top shell are all provided with clamping grooves for cooperating with the clamping strips.
[0018] With the above technical solution, the rotation of the meshing gear will drive the rack to move horizontally, and the movement of the rack will drive the vertical plate and the horizontal plate to move synchronously. The movement of the matching rack and the horizontal plate is guided by the mutual engagement of the engaging strip and the engaging groove.
[0019] The present invention is further configured as follows: the inner sides of the right bottom shell, the left bottom shell, the right top shell and the left top shell are each provided with a connecting block one fixedly connected to the other end of the ventilation pipe, one side of the connecting block one is respectively in contact with the horizontal plate and the rack, one side of the connecting block one is fixedly installed with a spring two, one end of the spring two is fixedly installed with a connecting block two, the four connecting blocks two are respectively fixedly connected to the inner sides of the right bottom shell, the left bottom shell, the right top shell and the left top shell, a surface of the ventilation pipe is slidably sleeved with a ring two, the four rings two are respectively fixedly connected to the inner sides of the right bottom shell, the left bottom shell, the right top shell and the left top shell, and a scale is opened on one side of the horizontal plate.
[0020] By adopting the above technical solution, during the movement of the rack and the cross plate, the contact extrusion force of the rack and the cross plate on one side of the connecting block one gradually fades, and the spring two gradually contracts, at which time the connecting block one moves and drives the vent pipe to move synchronously, while the sleeve two supports the vent pipe and reduces the friction on the surface of the vent pipe through a sliding connection, and the scale is read in coordination with the moving distance of the cross plate.
[0021] The present invention is further configured as follows: the rotating rod 1 and the rotating rod 2 are respectively rotatably connected to the inner sides of the right bottom shell and the left bottom shell, one end of the rotating rod 1 and the rotating rod 2 respectively penetrate the right bottom shell and the left bottom shell to the inner side of the connecting shell, the rotating rod 3 and the rotating rod 4 are respectively rotatably connected to the inner sides of the right top shell and the left top shell, the surfaces of the rotating rod 1 and the rotating rod 3 are fixedly sleeved with a ratchet inner ring 1, the surface of the ratchet inner ring 1 is engaged with a ratchet outer ring 1, the meshing gear located inside the right bottom shell and the right top shell and the ratchet outer ring 1 are fixedly sleeved with each other, the surfaces of the rotating rod 2 and the rotating rod 4 are fixedly sleeved with a ratchet inner ring 2, the surface of the ratchet inner ring 2 is engaged with a ratchet outer ring 2, the meshing gear located inside the left bottom shell and the left top shell and the ratchet outer ring 2 are fixedly sleeved with each other.
[0022] With the above technical solution, the counterclockwise rotation of the rotating rod 1 will drive the ratchet inner ring 1 on its surface to rotate synchronously, wherein the counterclockwise rotation of the ratchet inner ring 1 will drive the ratchet outer ring 1 to rotate synchronously through the ratchets, and when the ratchet outer ring 1 or the ratchet inner ring 1 is in clockwise rotation, the two cannot rotate synchronously. At the same time, the counterclockwise rotation of the rotating rod 2 will drive the ratchet inner ring 2 on its surface to rotate synchronously, wherein the clockwise rotation of the ratchet inner ring 2 will drive the ratchet outer ring 2 to rotate synchronously through the ratchets, and when the ratchet outer ring 2 or the ratchet inner ring 2 is in counterclockwise rotation, the two cannot rotate synchronously. Therefore, the directions in which the rotating rod 1 and the rotating rod 2 need to rotate are opposite.
[0023] The present invention is further configured as follows: the surfaces of the rotating rod one and the rotating rod two are fixedly sleeved with torsion springs, the other end of the torsion spring located on the surface of the rotating rod one is fixedly connected to the inner side of the right bottom shell, the other end of the torsion spring located on the surface of the rotating rod two is fixedly connected to the inner side of the left bottom shell, the surface of the rotating rod one is fixedly sleeved with an inner pulling piece, the surface of the rotating rod two is fixedly sleeved with an outer pushing piece, the surfaces of the rotating rod one, the rotating rod two, the rotating rod three and the rotating rod four are fixedly sleeved with synchronous wheels, two adjacent synchronous wheels are transmission-connected with a synchronous belt, and the synchronous belt passes through the connecting piece.
[0024] By adopting the above technical scheme, when the inner pulling member is pulled inward, the rotating rod 1 will be driven to rotate clockwise, and when the outer pushing member is pushed outward, the rotating rod 2 will be driven to rotate counterclockwise. Through the setting of the synchronous belt and the synchronous wheel, the synchronous rotation of the rotating rod 1 and the rotating rod 3, as well as the synchronous rotation of the rotating rod 2 and the rotating rod 4 will be realized, and the connecting member will protect and shield the synchronous belt.
[0025] In summary, the present invention has the following beneficial effects: When using the wall drilling device for assembled house construction, first adjust the position of the suction cup. Then run the rotary motor to achieve stable adsorption and fixation of the suction cup to the wall. At the same time, the operator adjusts the length of the ventilation pipe, and the rotating drill bit will gradually advance into the wall, at which time the stable drilling of the drilling device is achieved. This setting is conducive to improving the drilling stability, increasing the horizontality of the drilled hole, and ensuring the verticality of the hole and the wall. The user can relax the support force on the handle to reduce the user's arm discomfort caused by the weight of the drilling device during use. By ensuring the horizontality of the hole, the stability of the subsequent installation can be effectively guaranteed, avoiding the hidden danger of installation stability caused by insufficient drilling depth of the inclined hole; When using the wall drilling device for assembled house construction, the lengths of the four ventilation pipes inside the right bottom shell, the left bottom shell, the right top shell and the left top shell are adjusted respectively, so that the drilling depth of the drill bit can be observed in conjunction with the scale. When the inner pull piece is pulled inward, the ventilation pipe will be progressively moved inside the right bottom shell, the left bottom shell, the right top shell and the left top shell, and when the outer push piece is pushed outward, the ventilation pipe will be moved to the outside of the right bottom shell, the left bottom shell, the right top shell and the left top shell, so as to flexibly change the required drilling depth of the drill bit. This setting distinguishes the inconvenience of obtaining the drilling depth based on the skilled experience of the drilling master, increases the intuitiveness of the drilling depth, and makes drilling more convenient to use.

The bevel gear 2032 synchronously drives the rod body 2033 with the belt 30213, wherein the support plate 2034 will support the rod body 2033 and smoothly rotate the rod body 2033 through the bearing. The rotation of the rod body 2033 will drive the connecting plate 2035 to move, and the connecting plate 2035 drives the guide block 2036 at one end thereof to realize the running trend around the rod body 2033 as the center of the circle, so that the guide block 2036 drives the guide ring 2037 to reciprocate, and at the same time, the guide ring 2037 drives the connecting plate 2038 and the piston 2022 to move synchronously.
[0034] refer to Figure 2 , Figure 5 , Figure 8 An air inlet 2039 is provided at the top of the inner shell 2021, and a plug 20310 is provided on the inner side of the air inlet 2039. An inner rod 20312 is fixedly installed on the top of the plug 20310 and penetrates the top of the shell 101. A spring 20311 is sleeved on the surface of the inner rod 20312. The two ends of the spring 20311 are respectively fixedly connected to the plug 20310 and the inner side of the shell 101. A pinch block 20313 is fixedly installed on the top of the inner rod 20312. When the suction cup 2018 needs to be removed, the air inlet 2039 can achieve gas balance inside the inner shell 2021 by intake of air into the inner shell 2021. When air needs to be admitted to the air inlet 2039, the operator pinches the pinching block 20313, so that the pinching block 20313 drives the inner rod 20312 and the plug 20310 to move longitudinally. After the plug 20310 is separated from the air inlet 2039, air can be admitted to the air inlet 2039, and the spring 1 20311 will be contracted by the movement of the plug 20310. In the initial state, the extended state of the spring 1 20311 ensures the sealing effect of the plug 20310 on the air inlet 2039.
[0035] Brief description of the use process: When using the wall drilling device for assembled house construction, the position of the suction cup 2018 is adjusted first, so that when the suction cup 2018 contacts the wall, one end of the drill bit 108 does not contact the wall. Then run the rotary motor 103, and the operation of the rotary motor 103 will drive the driving rod 105 to rotate, wherein the fixing ring 104 supports and fixes the rotary motor 103. During the rotation of the driving rod 105, the mounting block 106 and the drill bit 108 will be driven to rotate, and the drill bit 108 will idle at this time. The mounting block 106 is fastened and installed with the drill bit 108 through a threaded connection, but when the drill bit 108 follows the rotation of the mounting block 106, the rotation trend is opposite to the thread direction, so the drill bit 108 will not slip off during work, and the threaded connection will ensure the convenience of installation and disassembly of the drill bit 108. The collar 107 will realize the smooth rotation of the mounting block 106 inside the housing 101 through the bearing. At the same time, the rotation of the driving rod 105 will drive the bevel gear 1 2031 to rotate, and the rotation of the bevel gear 1 2031 will drive the bevel gear 2 2032 to rotate, and the bevel gear 2 2032 will synchronously drive the rod body 2033 to rotate with the belt 30213, wherein the support plate 2034 will support the rod body 2033 and smoothly rotate the rod body 2033 through the bearing. The rotation of the rod body 2033 will drive the connecting plate 2035 to move, and the connecting plate 2035 drives the guide block 2036 at one end to realize the movement trend around the rod body 2033 as the center of the circle, so that the guide block 2036 drives the guide ring 2037 to reciprocate, and the guide ring 2037 drives the connecting plate 2038 and the piston 2022 to move synchronously. The sliding of piston 2022 will adjust and change the air inside inner shell 2021, and partition 2023 divides the inner shell 2021 into two parts. One-way valve 1 2024 cooperates with the gas on the other side of partition 2023 to only go out but not in, and fixed block 2025 cooperates with inner shell 2021 to support and fix. One-way valve 20210 cooperates with the gas inside inner shell 2021 and one side of partition 2023 to only go out but not in, bellows 2029 will transfer the gas inside vent pipe 2017 through connecting pipe 2019, and then the gas will come to the inner shell 2021 through tee pipe 2027 and pipeline 2026. Connecting shell 2015 is used between right bottom shell 2011 and left bottom shell 2012, and connecting piece 2016 is used between right bottom shell 2011 and right top shell 2013 and left bottom shell 2012 and left top shell 2014 respectively. When the suction cup 2018 is in contact with the wall, the air between the suction cup 2018 and the wall is extracted and transferred through the setting of the vent pipe 2017. At this time, the suction cup 2018 and the wall are firmly adsorbed and fixed.Then the operator adjusts the length of the vent pipe 2017. After adjusting the vent pipe 2017 toward the user, the suction cup 2018 is always fixed to the wall, and the rotating drill bit 108 will gradually advance into the wall, and the stable drilling use of the drilling device is achieved. This setting is conducive to improving the drilling stability, increasing the horizontality of the drilled hole, and ensuring the verticality of the hole and the wall. The user can relax the support force on the handle 102, reducing the user's arm discomfort caused by the weight of the drilling device during use. By ensuring the horizontality of the hole, the stability of the subsequent installation can be effectively guaranteed, and the hidden danger of installation stability caused by insufficient drilling depth of the inclined hole can be avoided. When the operator needs to cancel the fixed adsorption between the suction cup 2018 and the wall, the air inlet 2039 achieves gas balance inside the inner shell 221 by intake into the inner shell 221. When air needs to be admitted to the air inlet 2039, the operator pinches the pinching block 20313, so that the pinching block 20313 drives the inner rod 20312 and the plug 20310 to move longitudinally. After the plug 20310 is separated from the air inlet 2039, air can be admitted to the air inlet 2039, and the spring 1 20311 will be contracted by the movement of the plug 20310. In the initial state, the extended state of the spring 1 20311 ensures the sealing effect of the plug 20310 on the air inlet 2039.

During the movement of the rack 3013 and the cross plate 3012, the contact and extrusion pressure of the rack 3013 and the cross plate 3012 on one side of the connecting block 1 3017 gradually fades, and the spring 2 3018 gradually contracts, at which the connecting block 1 3017 moves and drives the vent pipe 2017 to move synchronously, and the sleeve ring 2 30110 supports the vent pipe 2017 while reducing the friction on the surface of the vent pipe 2017 through a sliding connection, and the scale 30111 is read in conjunction with the moving distance of the cross plate 3012.

At the same time, the counterclockwise rotation of the second rotating rod 3022 will drive the second ratchet inner ring 3028 on its surface to rotate synchronously, wherein the clockwise rotation of the second ratchet inner ring 3028 will drive the second ratchet outer ring 3027 to rotate synchronously through the ratchets, and when the second ratchet outer ring 3027 or the second ratchet inner ring 3028 is rotating counterclockwise, the two cannot rotate synchronously. Therefore, the rotation directions of the first rotating rod 3021 and the second rotating rod 3022 are opposite.
[0040] refer to Fig. 9 , Fig.13 , Fig.14The surfaces of the rotating rod 1 3021 and the rotating rod 2 3022 are fixedly sleeved with a torsion spring 3029, the other end of the torsion spring 3029 located on the surface of the rotating rod 1 3021 is fixedly connected to the inner side of the right bottom shell 2011, the other end of the torsion spring 3029 located on the surface of the rotating rod 2 3022 is fixedly connected to the inner side of the left bottom shell 2012, the surface of the rotating rod 1 3021 is fixedly sleeved with an inner pull piece 30210, the surface of the rotating rod 2 3022 is fixedly sleeved with an outer push piece 30211, the surfaces of the rotating rod 1 3021, the rotating rod 2 3022, the rotating rod 3 3023 and the rotating rod 4 3024 are fixedly sleeved with a synchronous wheel 30212, and the adjacent two A synchronous belt 30213 is provided for transmission connection between the synchronous wheels 30212, and the synchronous belt 30213 passes through the connecting piece 2016.

By setting the synchronous belt 30213 and the synchronous wheel 30212, the synchronous rotation of the rotating rod 1 3021 and the rotating rod 3 3023, as well as the synchronous rotation of the rotating rod 2 3022 and the rotating rod 4 3024 will be realized, and the connecting piece 2016 will protect and shield the synchronous belt 30213.
[0041] Brief description of the use process: When using the wall drilling device for assembled house construction, the lengths of the four ventilation pipes 2017 in the right bottom shell 2011, the left bottom shell 2012, the right top shell 2013 and the left top shell 2014 are adjusted respectively, so as to observe the drilling depth of the drill bit 108 in accordance with the scale 30111. When the operator needs to use the drill bit 108 to drill, he will use the inner pull piece 30210 and the outer push piece 30211 to achieve it. When the inner pulling piece 30210 is pulled inward, the ventilation pipe 2017 will be progressively advanced into the right bottom shell 2011, the left bottom shell 2012, the right top shell 2013 and the left top shell 2014, and when the outer pushing piece 30211 is pushed outward, the ventilation pipe 2017 will be moved to the outside of the right bottom shell 2011, the left bottom shell 2012, the right top shell 2013 and the left top shell 2014, so as to flexibly change the depth of the hole required by the drill bit 108. When the inner pull member 30210 is pulled inward, the rotating rod 1 3021 is driven to rotate clockwise, and when the outer push member 30211 is pushed outward, the rotating rod 2 3022 is driven to rotate counterclockwise. The synchronous belt 30213 and the synchronous wheel 30212 are arranged to realize the synchronous rotation of the rotating rod 1 3021 and the rotating rod 3 3023, and the synchronous rotation of the rotating rod 2 3022 and the rotating rod 4 3024. The connecting member 2016 protects and shields the synchronous belt 30213. The counterclockwise rotation of the rotating rod 1 3021 drives the ratchet inner ring 1 3026 on its surface to rotate synchronously. The counterclockwise rotation of the ratchet inner ring 1 3026 drives the ratchet outer ring 1 3025 to rotate synchronously through the ratchet. When the ratchet outer ring 1 3025 or the ratchet inner ring 1 3026 rotates clockwise, the two cannot rotate synchronously. At the same time, the counterclockwise rotation of the second rotating rod 3022 will drive the second ratchet inner ring 3028 on its surface to rotate synchronously, wherein the clockwise rotation of the second ratchet inner ring 3028 will drive the second ratchet outer ring 3027 to rotate synchronously through the ratchets, and when the second ratchet outer ring 3027 or the second ratchet inner ring 3028 is in counterclockwise rotation, it will be impossible for them to rotate synchronously. Therefore, the direction of rotation required by the first rotating rod 3021 and the second rotating rod 3022 is opposite. During the rotation of the meshing gear 3014, the rack 3013 will be driven to move horizontally, and during the movement of the rack 3013, the vertical plate 3011 and the horizontal plate 3012 will be driven to move synchronously. The movement of the matching rack 3013 and the horizontal plate 3012 is guided by the mutual engagement of the clamping strip 3015 and the clamping groove 3016.During the movement of the rack 3013 and the horizontal plate 3012, the contact and extrusion force of the rack 3013 and the horizontal plate 3012 on one side of the connecting block 1 3017 gradually fades, and the second spring 3018 gradually contracts, which causes the connecting block 1 3017 to move and drive the vent pipe 2017 to move synchronously, and the second collar 30110 supports the vent pipe 2017 and reduces the friction force on the surface of the vent pipe 2017 through sliding connection, and the scale 30111 is read in conjunction with the moving distance of the horizontal plate 3012. This setting is different from the inconvenience of obtaining the drilling depth based on the skilled experience of the drilling master, increases the intuitiveness of the drilling depth, and makes drilling more convenient to use.
