Description

Technical Field

[0001] This invention relates to the field of wall construction technology, and in particular to a drilling machine support device for drilling holes in building walls. Background Technology

[0002] Drilling is a common task in fields such as decoration and construction. Currently, there are various types of drilling machines on the market, among which conventional handheld drilling machines are widely used. For example, a well-drilling geological monitoring water drill disclosed in Chinese patent application CN202410305335.8 features multiple handles for easy hand-held application, offering flexibility and meeting drilling needs in various scenarios. Drilling machines with supports, such as the construction and installation water drill disclosed in Chinese patent application CN202123243316.8, while providing horizontal or vertical movement, require a mounting mechanism and lack a handle; they are non-standard machines specifically designed for use with supports. Decoration teams typically own multiple models and specifications of drilling machines and, for flexibility, prefer handheld drilling machines. However, handheld drilling machines are inconvenient to operate and pose high safety risks when performing high-altitude drilling operations such as drilling into side walls or ceilings. Drilling machines fixed to a support frame have limited application scenarios and low usage frequency, requiring operators to carry both a handheld drilling machine and a high-altitude wall drilling machine, which undoubtedly increases procurement costs. Therefore, developing a support frame that can accommodate the limit settings of different models of handheld drilling machines, allowing the handheld drilling machine to be combined with the support frame to form a high-altitude drilling machine, is of significant practical importance. Summary of the Invention

[0003] This invention addresses the drawback of existing renovation teams needing to equip themselves with both handheld and aerial drilling machines, resulting in high purchase costs. It provides a support device for drilling machines used in building walls, capable of quickly clamping different models of handheld drilling machines.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A drilling machine support device for drilling holes in building walls includes: a movable support, comprising a support body that can be moved horizontally and is limited after being moved horizontally, and a mounting base that can be vertically raised and lowered along the support body and is limited in position; and further comprising...

[0006] The flip clamping module includes a flip frame and a clamping module. The flip frame moves back and forth on the mounting base along the drilling direction of the drilling machine. The clamping module includes a clamping box that is rotatably mounted on the flip frame and can be limited after each preset angle of rotation, and clamping components that are circumferentially spaced on the inner ring wall of the clamping box.

[0007] The clamping assembly includes a plurality of clamping members spaced apart along the insertion direction of the clamping box. The clamping members are elastically telescopically arranged in a direction perpendicular to the insertion direction of the clamping box, and the telescopical extension of all the clamping members is controlled by a first electromagnetic control assembly.

[0008] The locking component can simultaneously lock or unlock all clamping parts that are in the extended state and have different extension strokes.

[0009] The above solution incorporates a flip-clamping module. The clamping box of this module can be limited at certain angles relative to the flip frame. The design aims to address the issue that different models of handheld drilling machines have different handle angles. By adjusting the angle of the clamping box, the final drill bit of the drilling machine can be kept horizontal or vertically upward, ensuring that the drilling direction is consistent with the drill bit's direction. The added clamping module includes several clamping components. These components, when partially extended, can elastically fit against the outer wall of the drilling machine's insertion end with different curvatures and shapes. A locking component limits all clamping components with different strokes, forming an interference-fitting cavity around the drilling machine's insertion end. This achieves axial and circumferential limiting of the drilling machine. The support device carries the clamping box, enabling vertical lifting and horizontal reciprocating motion, adaptable to handheld drilling machines of different sizes and models.

[0010] Preferably, the locking assembly includes a first rack and a first toothed block. The first rack is located on the outer wall of each clamping member and is arranged along its extension and retraction direction. The first toothed block elastically extends and retracts within the clamping box and can engage or disengage with the first rack. The first toothed block extends and retracts synchronously and is controlled by the inclined surface engagement assembly.

[0011] Preferably, the inclined mating assembly includes a drive rod that elastically extends and retracts to the bottom of the clamping box. The number of drive rods is the same as the number of clamping assemblies. The end of the drive rod near the clamping box includes a mating inclined block that corresponds one-to-one with the clamping member in the corresponding clamping assembly and a clearance link connecting adjacent mating inclined blocks. A first mating through groove that mates with the mating inclined block is provided on the first tooth block. When the drive rod extends elastically, the first tooth block is in a retracted state; when the drive rod retracts, the first tooth block is in an extended state.

[0012] Using the above scheme, the extension and retraction of all the first tooth blocks can be controlled synchronously by controlling the extension and retraction of the drive rod. Since the extension stroke of all the clamping parts is related to the shape of the drilling machine insertion end, if the insertion end is irregular, the extension stroke of the clamping parts will inevitably be inconsistent. This will result in not all the first tooth blocks being able to mesh with their corresponding clamping parts, which will inevitably lead to different extension strokes of the first tooth blocks. However, the above design will not interfere with the extension amount of the first tooth blocks. Therefore, there will inevitably be a certain number of first tooth blocks that mesh with the clamping parts, thereby forming a corresponding number of clamping parts' extension and retraction restrictions.

[0013] Preferably, each clamping component has two first toothed blocks that are directly opposite each other and the two first toothed blocks are in a staggered tooth distribution state. The driving rod includes a main rod that is inserted into the bottom of the clamping box and a split rod that is engaged with the first toothed blocks on both sides of the clamping component. The split rod is formed by the inclined block and the avoidance link.

[0014] The above scheme is adopted, with a first tooth block on each side of the clamping member, and the two are in a staggered tooth state and are synchronously controlled by the same drive rod. The design is that the first tooth blocks on both sides move synchronously. Since the two are staggered, there must be a first tooth block that can mesh with the clamping member. This design can increase the number of clamping members that can be restricted and improve the clamping performance.

[0015] Preferably, a press-adsorption component is elastically extendable at the center of the bottom of the clamping box to adsorb the end of the drill bit insertion and limit the insertion depth. The press-adsorption component includes a press-adsorption mechanism and a locking mechanism. The press-adsorption mechanism forms a negative pressure and adsorbs the drill bit insertion as the drill bit insertion is inserted and partially retracted. The locking mechanism restricts the movement of the press-adsorption mechanism after retraction.

[0016] By adopting the above solution and adding an adsorption structure to the insertion end of the drilling machine, the firmness of clamping the drilling machine can be further increased.

[0017] Preferably, the pressing and adsorption mechanism includes a fixed tube fixed at the center of the bottom of the clamping box, a movable tube elastically sealed outside the fixed tube, an exhaust valve for one-way exhaust at the end of the fixed tube away from the opening of the clamping box, and an air supply component that can be opened and closed on the fixed tube.

[0018] Using the above scheme, the exhaust valve can discharge the gas between the fixed pipe and the moving pipe. When the moving pipe moves in the opposite direction, a negative pressure will be formed at the sealing point between the end of the moving pipe and the drilling machine.

[0019] Preferably, the locking mechanism includes a second rack and a second toothed block. The second rack is located on the outer wall of the pressing and adsorption mechanism and is arranged along its extension and retraction direction. The second toothed block elastically extends and retracts within the clamping box and can engage or disengage with the second rack. The retraction of the second toothed block is controlled by a second electromagnetic control component.

[0020] Preferably, the extension and retraction of the drive rod is controlled by the extension and retraction of the second tooth block. The second tooth block is perpendicularly inserted into the main rod. The main rod is provided with a second mating groove. The second tooth block has a pressing inclined surface that mates with the second mating groove. When the second tooth block extends, the main rod retracts; when the second tooth block retracts, the main rod extends elastically.

[0021] Using the above scheme, the movement of the drive rod and the movement of the second tooth block are linked and coordinated. The synchronous limiting of all clamping parts and the limiting of the moving tube can be achieved by a set of electromagnetic control components. In conventional cases, the movement trend of the moving tube is opposite to that of the drive rod, which requires two sets of electromagnets with opposite energization and de-energization states. Each set may require the number of electromagnets to be set according to the number of drive rods and connected in series, which has problems such as insufficient internal installation space and messy and difficult wiring. This design can solve the above problems.

[0022] Preferably, an air path control component is provided between the clamping member and the clamping box, which can synchronously realize the independent change of air pressure of each clamping member.

[0023] Preferably, the gas path control component includes

[0024] An independent air circuit assembly includes a first air groove provided in each clamping member, several independent second air grooves connected to the bottom of the clamping box, and connecting hoses connecting the first air grooves and the second air grooves.

[0025] The air extraction assembly includes a piston plate and piston rods that move and seal within a second air groove. All piston rods are synchronously connected to the piston plate. The piston plate moves and seals within a first mating cavity. All piston plates are synchronously connected to a movable plate. The movement of the movable plate is controlled by a cylinder built into a clamping box.

[0026] By adopting the above scheme, the movement of the moving plate is controlled by the extension and retraction of the cylinder, thereby realizing the synchronous movement of all piston rods and achieving independent control of the internal air circuit of each clamping component. The clamping components in contact with the drilling machine can be adsorbed onto the drilling machine, further increasing the firmness of clamping the drilling machine.

[0027] Preferably, the two ends of the clamping box are rotatably connected to the flipping frame via a rotating shaft. The flipping frame has a meshing toothed disc that extends and retracts along the axial direction of the rotating shaft. The movement of the meshing toothed disc is controlled by a screw handle. The outer wall of the clamping box has a mating tooth groove fixed around the rotating shaft for the meshing toothed disc to engage.

[0028] Using the above method, the axial position of the meshing gear disc can be adjusted by rotating the screw handle, thereby achieving engagement or disengagement between the meshing gear disc and the mating tooth groove.

[0029] Preferably, the support body includes a moving component and a supporting component. The moving component includes a moving base, rollers rotating on the moving base, and an adsorption component that can adsorb or desorb from the ground. The supporting component includes a fixed frame fixed on the moving base and a lifting frame that rises and falls vertically on the upper end of the fixed frame, with the mounting seat rising and falling vertically on the lifting frame.

[0030] Using the above solution, the movable base moves via rollers and is limited by an adsorption component. The vertical lifting of the lifting frame relative to the fixed frame adjusts the maximum stroke of the flip-grip module, while the lifting frame is used to ensure the accuracy of the flip-grip module's lifting. This invention, due to the adoption of the above technical solutions, has significant technical effects: the movable base achieves rapid movement on the ground via rollers, and after moving to a designated position, it can be limited by adsorption; the lifting frame's lifting stroke can be adjusted to its maximum stroke; the vertical movement of the mounting base achieves the final height reached by the drilling machine; the drilling machine moves horizontally on the mounting base to advance or retract; the angle adjustment of the drilling machine on the flip-grip ensures that the drilling direction of the clamped drilling machine remains horizontal or vertical; and the internal clamping component contains multiple clamping members that elastically extend... It can elastically conform to the outer wall of the drill handle or insertion part with different degrees of undulation, while the pressing and adsorption component can provide negative pressure to limit the end face of the drill insertion part. Finally, the locking component locks all the clamping parts and moving tubes with different extension strokes, ensuring the maintenance of locking force and adsorption force. At the end of the clamping parts, negative pressure can also be formed to further increase the limit of the drill insertion part and ensure the stable operation of the drill. This support device can be adapted to the limit of drills of different sizes and models, and ensures that the drilling direction of the drill can be adjusted to horizontal or vertical upward after the drill is limited.

Detailed Implementation

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0042] A drilling machine support device for drilling holes in building walls, as shown in the reference. Figures 1-10 As shown, it includes a movable support and a flip-clamping module. The movable support can be moved horizontally and then limited after being moved horizontally. The flip-clamping module is used to clamp different types of drilling machines and carry the drilling machines to move vertically or horizontally along the movable support.

[0043] See details Figures 1-2As shown, the mobile bracket includes a bracket body and a mounting base 10. The bracket body includes a moving component and a supporting component. The moving component includes a moving base 1, rollers 2 rotating on the moving base 1, and an adsorption component that can adsorb or desorb from the ground. The adsorption component includes a first height adjustment handle 42 vertically screwed to the moving base 1. A rigid suction cup 41 is rotatably fitted at the bottom of the first height adjustment handle 42. A rubber ring is fixed to the bottom edge of the base. A piston is sealed and movable inside the suction cup 41. A second height adjustment handle 43 is rotatably mounted on the upper end of the piston. The second height adjustment handle 43 is screwed into the central threaded hole of the first height adjustment handle 42. The first height adjustment handle 42 can realize the vertical raising and lowering of the suction cup 41. The second height adjustment handle 43 can realize the raising and lowering of the piston, thereby realizing the adsorption and desorption of the suction cup 41 from the ground, and realizing the limitation or release of the limitation of the mobile base 1. The support assembly includes a fixed frame 3 fixed to the movable base 1 and a lifting frame 4 vertically raised and lowered on the fixed frame 3. Adjusting rods are vertically protruding from both sides of the upper end of the fixed frame 3, and slots for inserting the adjusting rods are recessed from both sides of the lower end of the lifting frame 4. Several pin holes 7 are vertically spaced on the adjusting rods. Pins 5, which pass through the lifting frame 4 and engage with the pin holes 7, are provided on the outer walls of both sides of the lifting frame 4. A first lead screw 8 rotates vertically on the lifting frame 4, and its rotation is controlled by a first motor 6. A lifting slider 9 moves vertically within the lifting frame 4, and a first nut that mates with the first lead screw is fixed inside the lifting slider 9. The lifting slider 9 extends out of the lifting frame 4 to form a mounting base 10. A second lead screw rotates inside the mounting base 10, and its rotation is controlled by a second motor. A horizontal slider slides along the mounting base 10, and a second nut that mates with the second lead screw is fixed inside the horizontal slider. A flip-clamping module is fixed to the horizontal slider.

[0044] Flip clamping module, see details Figure 3 As shown, the device includes a flipping frame 11 and a clamping module. The flipping frame 11 is U-shaped and its bottom is welded or fixed to a horizontal slider by screws or other connecting parts. The clamping module includes a clamping box 12 with one side open. The two sides of the clamping box 12 are rotated on the flipping frame 11 via a rotating shaft 13. Several sets of clamping components are circumferentially spaced on the inner ring wall of the clamping box 12. Each set of clamping components is spaced along the axial direction of the clamping box 12 and has several clamping members 21 that extend and retract radially along the clamping box 12. All clamping members 21 extend and retract synchronously and are controlled by a first electromagnetic control component.

[0045] Each side of the tilting frame 11 has a meshing toothed disc 14 that reciprocates along the axial direction of the rotating shaft 13. (See also...) Figure 4As shown, a connecting frame 15 is inserted into the flipping frame 11. The connecting frame 15 is U-shaped and its two ends are fixedly connected to the meshing toothed disc 14. A screw handle 16 is screwed onto the end of the connecting frame 15 away from the opening. The screw handle 16 is rotatably engaged with the outer wall of the flipping frame 11. By rotating the screw handle 16, the meshing toothed disc 14 can be engaged or disengaged from the mating tooth groove, thereby achieving the limiting position of the clamping box 12 after the angle relative to the flipping frame 11 is adjusted.

[0046] Combination Figure 5 As shown, the clamping member 21 extends and retracts on the inner wall of the clamping box 12 and can be in an elastically extended state under the control of the second elastic member 27. The first electromagnetic control component includes a first electromagnet 25 fixed in the inner wall of the clamping box 12. The two ends of the second elastic member 27 are fixedly connected to the clamping member 21 and the first electromagnet 25 respectively. The clamping member 21 is made of iron and its clamping end is fixed with a rubber layer. When the first electromagnet 25 is energized, the clamping member 21 is in a retracted state; when the first electromagnet 25 is de-energized, the clamping member 21 elastically extends.

[0047] A locking assembly is provided on the clamping box 12 to simultaneously restrict all extended clamping members 21, combined with Figures 8-9 As shown, the locking assembly includes a first rack 35 and a first toothed block 36. The first rack 35 is located on the outer wall of each clamping member 21 and is arranged along its extension and retraction direction. The first toothed block 36 elastically extends and retracts within the clamping box 12 and can engage or disengage with the first rack 35. The first toothed block 36 extends and retracts synchronously and is controlled by the combined action of the fourth elastic member 40 and the inclined surface engagement assembly. (Refer to...) Figure 9As shown, the first toothed block 36 has a guide rod 39 protruding from the end away from the tooth surface, which is inserted into the clamping box 12. The inclined mating assembly includes a drive rod that elastically extends and retracts at the bottom of the clamping box 12. The number of drive rods is the same as the number of clamping assembly groups. The end of the drive rod near the clamping box 12 includes a mating inclined block 37 that corresponds one-to-one with the clamping member 21 in the corresponding clamping assembly and a clearance link 38 connecting adjacent mating inclined blocks 37. A first mating through groove 361 that mates with the mating inclined block 37 is provided on the first toothed block 36. The fourth elastic member 40 is sleeved on the guide rod 39 and elastically abuts against the second toothed block 30 and the inner wall of the clamping box 12. When the drive rod elastically extends, the first toothed block 36 is in a retracted state, and the clamping member 21 is in an unlocked state. When the drive rod retracts, the first toothed block 36 is in an extended state, and the clamping member 21 is in a locked state. Each clamping member 21 has two first toothed blocks 36 that are directly opposite each other and are in a staggered toothed state. The driving rod includes a main body rod 33 that is inserted into the bottom of the clamping box 12 and a split rod that engages with the first toothed blocks 36 on both sides of the clamping member 21. The split rod is formed by the inclined block 37 and the avoidance link 38. This arrangement ensures that there is a first toothed block 36 that can mesh with the first rack 35, thereby improving the locking efficiency of the clamping member 21. All the split rods and the main body rod 33 are synchronously fixed on a synchronous ring 23. The synchronous ring 23 can ensure that all the main body rods 33 and the split rods run synchronously.

[0048] At the bottom center of the clamping box 12, there is a retractable pressing suction component that can hold the insertion end of the drilling machine and limit the insertion depth. See Figure 4 As shown, the press-adsorption assembly includes a press-adsorption mechanism and a locking mechanism. The press-adsorption mechanism creates negative pressure and adsorbs the insertion end of the drilling machine as the drilling machine inserts and partially retracts. The locking mechanism restricts the movement of the press-adsorption mechanism after retraction.

[0049] The press-adsorption mechanism includes a fixed tube 17 fixed at the center of the bottom of the clamping box 12 and a movable tube 19 elastically sealed outside the fixed tube 17. One end of the fixed tube 17 away from the opening of the clamping box 12 is provided with an exhaust valve (not shown) that allows for one-way exhaust. The exhaust valve is an existing structure without modification, and its specific structure will not be described here. An air supply component 18, capable of opening and closing the internal air chamber of the fixed tube 17, is screwed onto the fixed tube 17. The locking mechanism includes a second rack 191 and a second tooth block 30, combined with... Figure 7As shown, the second rack 191 is located on the outer wall of the moving tube 19 and extends along the axial direction of the moving tube 19. The number of sets of the second rack 191 and the second tooth block 30 is the same as that of the clamping assembly, which is four sets. The second tooth block 30 is elastically extended and retracted in the clamping box 12 by the third elastic member 32 and the second electromagnet 31 and can engage or disengage with the second rack 191. The second electromagnet 31 is fixed inside the clamping box 12. The two ends of the third elastic member 32 are fixedly connected to the second tooth block 30 and the second electromagnet 31 respectively. The second tooth block 30 is made of iron.

[0050] The extension and retraction of the drive rod is controlled by the extension and retraction of the second tooth block 30. The second tooth block 30 is perpendicularly inserted into the main rod 33. The main rod 33 is provided with a second mating groove 34. The second tooth block 30 has a pressing inclined surface 3001 that mates with the second mating groove 34. A fifth elastic element 44 connected to the main rod 33 is provided in the clamping box 12. When the second electromagnet 31 is de-energized, the second tooth block 30 extends, the pressing inclined surface 3001 presses against the second mating groove 34 and drives the main rod 33 to retract. When the second electromagnet 31 is energized, the second tooth block 30 retracts, and the main rod 33 extends elastically under the drive of the fifth elastic element 44. The above structure enables the movement of the drive rod and the movement of the second tooth block 30 to be linked. Thus, the energization or de-energization of the second electromagnet 31 can control the synchronous limiting of all clamping parts 21 and moving tube 19. This design can significantly reduce the difficulty of wiring, reduce the number of electromagnet sets, and reduce the space occupied by unnecessary parts.

[0051] An air path control component is provided between the clamping member 21 and the clamping box 12, combined with... Figures 4-6 As shown, the air path control assembly can synchronously realize the independent change of air pressure of each clamping member 21. The air path control assembly includes an independent air path assembly and an air extraction assembly. The independent air path assembly includes a first air groove 24 provided in each clamping member 21, several independent second air grooves connected to the first air groove 24 at the bottom of the clamping box 12, and a connecting hose 26 connecting the first air groove 24 and the second air groove. The air extraction assembly includes a piston plate 28 and a piston rod 281 that moves and seals within the second air groove. All piston rods 281 are synchronously connected to the piston plate 28. The piston plate 28 moves and seals within the first mating cavity. All piston plates 28 are synchronously connected to a moving plate 29. The movement of the moving plate 29 is controlled by a cylinder 22 built into the clamping box 12. The piston rod end of the cylinder 22 is fixedly connected to the moving plate 29.

[0052] The first elastic element 20, the second elastic element 27, the third elastic element 32, the fourth elastic element 40, and the fifth elastic element 44 are all springs. The elastic force between these springs can be selected according to actual needs. The electromagnetic control valve of cylinder 22, the first motor 6, the second motor, the first electromagnet 25, and the second electromagnet 31 are all connected to the PLC. A touch screen (not shown) connected to the PLC is installed on the mounting bracket 3. The operator can use the touch screen to control the opening and closing of the first electromagnet 25 and the second electromagnet 31, switch the electromagnetic control valve of cylinder 22, switch the forward and reverse rotation of the first motor 6 and the second motor 6, and perform other commands such as opening and closing. Using the touch screen to control the opening, closing, and switching of the above components by the PLC is existing technology and will not be described in detail here.

[0053] Operating steps:

[0054] 1. Clamping the drilling machine:

[0055] 1.1 Initial state: The first electromagnet 25 is energized and the second electromagnet 31 is energized. At this time, the first tooth block 36, the second tooth block 30 and the clamping member 21 are all in the retracted state, and the piston rod 281 of the cylinder 22 is in the extended state.

[0056] 1.2 Clamping: Insert the part of the handheld drill to be clamped (lower handle or tail handle) into the opening of the clamping box 12. After the drill insertion end presses against the moving tube 19 and moves inward to the maximum insertable position, it retracts outward by 1 / 5 to 1 / 3 of the insertion stroke. It is advisable to make the negative pressure at the insertion end of the drill feel palpable to the human. At this time, firstly, de-energize the first electromagnet 25, and the clamping member 21 extends elastically and clamps on the outer wall of the insertion end of the drill. Then, drive the second electromagnet 31 to de-energize, and the second tooth block 30 extends to restrict the movement of the moving tube 19. The extension of the second tooth block 30 drives the drive rod to retract, and the second tooth block 30 extends and meshes with the first rack 35 on the clamping member 21 to restrict the movement of the clamping member 21. Finally, drive the piston rod 281 of the cylinder 22 to retract, and the negative pressure at the contact point between the clamping member 21 and the drill increases to achieve adsorption.

[0057] 1.3 Drilling machine angle adjustment: Rotate the screw handle 16 to first disengage the meshing gear plate 14 from the mating gear groove, rotate the clamping box 12 until the drill bit of the drilling machine is in a horizontal or vertically upward state (adjust according to the drilling position), and then rotate the screw handle 16 in the opposite direction until the meshing gear plate 14 meshes with the mating gear plate again.

[0058] 2. Movement and limiting of the movable bracket: Push the movable bracket to the vicinity of the position to be drilled, first turn the first height adjustment handle 42 to achieve elastic pressure between the suction cup 41 and the ground; then turn the second height adjustment handle 43 to move the piston upward, so that the negative pressure at the contact point between the suction cup 41 and the ground continuously increases until it firmly adheres to the ground.

[0059] 3. Maximum travel adjustment: Adjust the position of pin 5 according to the actual height;

[0060] 4. Drilling: Turn on the start button on the drill, then start the first motor 6, raise the mounting base 10 to the required drilling height, and then turn off the first motor 6; start the second motor 6, move the moving base 1 carrying the drill to the drilling position and drill; after drilling, switch the second motor 6 to reverse until it is detached from the wall; then switch the first motor 6 to reverse, lower the mounting base 10 to its maximum stroke, turn off the drill, and finally release the suction cup 41. At this time, the drill is still in the clamped state, waiting for the next drilling of the wall. If the drill needs to be replaced or removed, the second electromagnet 31 must first be energized, then the piston rod 281 of the cylinder 22 should be extended, further energizing the first electromagnet 25. Finally, the air supply component 18 should be opened to supply air. The drill will automatically detach outward under the restoring force of the first elastic element 20 between the moving tube 19 and the fixed tube 17. The operator only needs to grab the drill to easily remove it.
