Description

Technical Field

[0001] The invention relates to a processing device for water supply and drainage pipes, in particular to a turning machine tool. Background Art

[0002] Mesh bag pipes are widely used in the fields of water supply and drainage pipelines. They are used to transport various fluid media. After long-term use, the inner wall of the mesh bag pipe is seriously crystallized. Due to the long length of the mesh bag pipe, it is difficult to manually clean the crystal layer on its inner wall. For example, if the current turning equipment is used to clean the inner wall of the mesh bag pipe, the turning tool needs to move a long distance along the axial direction of the mesh bag pipe, and the structure of the turning tool transmission cannot provide support inside the mesh bag pipe, and it is difficult to ensure the coaxiality of the turning tool moving inside the mesh bag pipe, resulting in poor accuracy of the turning tool in the process of cleaning the crystal layer on the inner wall of the mesh bag pipe, and the mesh bag pipe is easily damaged. Therefore, there is an urgent need for a machine tool suitable for turning the inner wall of a pipe such as a mesh bag pipe. Summary of the invention

[0003] The purpose of the present invention is to provide a turning machine tool to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problem is: A turning machine tool comprises: a rotating device having a transmission sleeve that can rotate along a horizontal axis; a pipe clamping device, which is arranged on the outside of the transmission sleeve, and the pipe clamping device is located at one end of the transmission sleeve to form an openable and closable pipe clamping area; a processing device, including a linear drive, a feed regulator, a positioner and a tool, the linear drive having a movable seat that can move toward or away from the pipe clamping area, the feed regulator is arranged on the movable seat, the feed regulator has an adjustment seat that can move radially along the transmission sleeve, the positioner and the tool are connected to the adjustment seat, the positioner is used to detect the offset value between the tool and the axis of the transmission sleeve, and the adjustment seat is configured to move radially according to the offset value.

[0005] The technical solution has at least the following beneficial effects: the tube clamping area formed in the tube clamping device is opened, and the tube body to be turned and processed is inserted into the tube clamping area. When working, the transmission sleeve in the rotating device rotates, and drives the tube clamping device and the tube body to rotate together. The linear drive in the processing device drives the movable seat to move into the tube body, and the tool on the adjustment seat is used to turn and clean the inner wall of the tube body. When the linear drive drives the movable seat to move in the direction close to or away from the tube clamping area, that is, drives the movable seat to move in the axial direction of the tube body in the tube body, the positioner on the adjustment seat can detect the position of the tool and the transmission sleeve. The offset value between the sleeve axis. When the tool moves along the axial direction of the tube body and deviates from the axis of the transmission sleeve, the adjustment seat can move along the radial direction of the tube body according to the offset value, thereby compensating for the offset error caused by the bending deformation of the linear drive due to the excessive length of the tool during movement, and effectively ensuring the coaxiality of the tool with the tube body when it moves in the tube body. In this way, the displacement of the tool fed to the inner wall of the tube body is adjusted in real time, thereby ensuring the accuracy of the processing of the inner wall of the tube body, realizing automatic cleaning of the inner wall of the tube body, and completing the precision turning of the tube body, which is especially suitable for tubes such as mesh bag tubes with longer lengths.

[0006] As a further improvement of the above technical solution, the linear drive includes a mounting seat, a first motor, an outer sleeve and a screw, the first motor and the outer sleeve are respectively connected to the mounting seat, the screw is rotatably connected to the mounting seat, the screw is located in the outer sleeve, the first motor is transmission-connected to the screw, the movable seat is threadedly connected to the screw, the movable seat is slidably connected to the outer sleeve, an avoidance slot is provided on the outer side of the outer sleeve along its axial direction, the adjustment seat extends out of the outer sleeve from the avoidance slot, and the positioner and the tool are respectively connected to the position where the adjustment seat extends out of the outer sleeve. When in use, the tube body that needs to be turned and cleaned can be sleeved on the outside of the outer sleeve. The outer sleeve can surround and protect the screw to reduce the exposure of the structure. The aligner and the tool are connected to the position where the adjustment seat extends out of the outer sleeve to better protect the transmission structure. The outer sleeve and the screw both extend in the tube body and can provide support for the axial movement of the movable seat in the tube body. When it is necessary to control the movement of the tool, the first motor works to drive the screw to rotate. Since the movable seat is threadedly connected to the screw and the movable seat is slidably connected in the outer sleeve, as the screw rotates, the movable seat can be driven to slide axially in the outer sleeve. Since the length of the outer sleeve and the screw is long, it is difficult to ensure the straightness of the outer sleeve and the screw. Therefore, the aligner is used to detect the offset value between the axial movement of the tool along the tube body and the axis of the transmission sleeve. In this way, the displacement of the tool feeding to the inner wall of the tube body is adjusted in real time to compensate for the downward bending deformation of the outer sleeve and the screw due to gravity, thereby ensuring the accuracy of machining the inner wall of the tube body.

[0007] As a further improvement of the above technical solution, the present invention further includes a first support frame and a second support frame, wherein the first support frame is surrounded to form a first support area, and the second support frame is surrounded to form a second support area, and the two ends of the outer sleeve extend into the first support area and the second support area respectively. The first support area formed by the first support frame and the second support area formed by the second support frame are used to support and position the two ends of the outer sleeve respectively, effectively reducing the situation where the outer sleeve is bent under pressure at the end position, and improving the stability of the movable seat when sliding in the outer sleeve.

[0008] As a further improvement of the above technical solution, the present invention also includes a base, the base is located on the side of the first support frame away from the second support frame, the mounting seat is slidably connected to the base, and a translation driver is provided between the mounting seat and the base, and the translation driver can drive the mounting seat to slide in a direction close to or away from the second support frame. When it is necessary to load and unload the tube body, the translation driver can be used to drive the mounting seat to slide on the base in a direction away from the second support frame, at which time the outer sleeve and the screw can be driven to leave the second support frame, so that a space is formed between the first support frame and the second support frame into which the tube body can be directly placed, so that the tube body can be easily assembled and disassembled from the tube clamping area, and then the translation driver drives the mounting seat to slide in a direction close to the second support frame, and the outer sleeve and the screw are inserted into the tube body, so that the tool can perform turning and cleaning on the inner wall of the tube body that needs to be processed.

[0009] As a further improvement of the above technical solution, the alignment device includes a receiving plate and a laser emitter. The receiving plate is provided at at least one side of the movable path of the movable seat, and the laser emitter is connected to the position of the adjusting seat corresponding to the receiving plate. When the outer sleeve or the screw is deformed, when the movable seat moves to the deformed position, the position where the tool feeds to the tube body will be offset. At this time, the emitter on the adjusting seat will be offset to the emission point of the receiving plate. According to the position where the receiving plate receives the laser, the offset value between the tool and the axis of the transmission sleeve can be obtained. The adjusting seat performs radial activity compensation according to the offset value to achieve precise processing of the inner wall of the tube body.

[0010] As a further improvement of the above technical solution, the feed adjuster includes an adjusting screw and an adjusting rod, the adjusting screw is connected to the movable seat, the adjusting screw is driven and connected to the adjusting rod, the adjusting screw can drive the adjusting rod to move in a direction away from or close to the transmission sleeve, a guide section is formed on the adjusting rod and extends obliquely in a direction away from the axis of the transmission sleeve, the adjusting seat is connected to the movable seat along the radial sliding direction of the transmission sleeve, and the guide section is inserted into the adjusting seat. The adjusting screw can adjust the position of the adjusting rod along the axial movement of the tube body, which can reduce the demand for radial installation space of the adjusting screw and the adjusting rod in the outer sleeve, so that the driving source that drives the adjusting seat to move can be compactly installed in the outer sleeve. When it is necessary to increase the feed depth of the tool to the tube body, the adjusting screw drives the adjusting rod to move closer to the adjusting seat. Since the guide section on the adjusting rod is inclined away from the axis of the transmission sleeve, the guide section can guide the adjusting seat so that the tool on the adjusting seat moves closer to the inner wall of the tube body. When it is necessary to reduce the feed depth of the tool to the tube body, the adjusting screw drives the adjusting rod to move away from the adjusting seat. Similarly, the adjusting seat is guided by the guide section so that the tool on the adjusting seat moves away from the inner wall of the tube body. In this way, the tool can be driven to move and adjust along the radial direction.

[0011] As a further improvement of the above technical solution, the rotating device includes a base frame and a second motor, the base frame is connected to a fixed sleeve, the transmission sleeve is rotatably connected in the fixed sleeve, the second motor is connected to the base frame, and the second motor is in transmission connection with the transmission sleeve. The transmission sleeve is rotatably installed in the fixed sleeve, which can improve the stability of the transmission sleeve installation. When working, the second motor provides a rotational driving force to the transmission sleeve, driving the transmission sleeve to rotate, thereby driving the tube body to rotate through the tube clamping device.

[0012] As a further improvement of the above technical solution, the tube clamping device is a three-jaw chuck. The three-jaw chuck has three clamping jaws that can move away from or close to each other, and a clamping area that can be opened and closed is formed between the three clamping jaws. When the three clamping jaws move away from each other, the clamping area is opened to load or unload the tube body, and when the three clamping jaws move close to each other, the clamping area is closed to clamp the tube body.

[0013] As a further improvement of the above technical solution, the present invention also includes a limit frame, wherein a plurality of limit wheels are arranged in a circular array around the axis of the transmission sleeve, and a limit area is formed between the plurality of limit wheels, and the limit area is directly opposite to the tube clamping area. When the tube body is loaded, the tube body can enter the limit area, and the plurality of limit wheels are used to abut against the outer wall of the tube body to provide support for the tube body. In this way, the limit frame is used to provide support for the outer side of the tube body, which can improve the stability of the rotation of the tube body.

[0014] As a further improvement of the above technical solution, a plurality of limit frames are arranged at intervals in a direction away from the pipe clamping area. The plurality of limit frames can provide support at different positions of the pipe body, effectively preventing the pipe body from bending downward due to excessive length, and further improving the stability of the pipe body rotation.

[0025] Reference Figure 1 A turning machine tool comprises a rotating device 100, a pipe clamping device 200 and a processing device, wherein the rotating device 100 has a transmission sleeve 110 that can rotate along a horizontal axis; the pipe clamping device 200 is arranged outside the transmission sleeve 110, and the pipe clamping device 200 is located at one end of the transmission sleeve 110 to form an openable and closable pipe clamping area; the processing device comprises a linear drive, a feed regulator, a positioner and a tool 320, the linear drive has a movable seat 337 that can move close to or away from the pipe clamping area, the feed regulator is arranged on the movable seat 337, and the feed regulator has an adjustment seat 331 that can move radially along the transmission sleeve 110 The aligner and the tool 320 are connected to the adjustment seat 331. The aligner is used to detect the offset value between the tool 320 and the axis of the transmission sleeve 110. The adjustment seat 331 is configured to perform radial movement according to the offset value. In actual applications, when the tool 320 is normally processing the inner wall of the tube body, the distance between the tool 320 and the axis of the transmission sleeve 110 is the normal feed value. When the offset value is greater than the normal feed value, the adjustment seat 331 moves in a direction away from the axis of the transmission sleeve 110. When the offset value is less than the normal feed value, the adjustment seat 331 moves in a direction close to the axis of the transmission sleeve 110, thereby compensating for the offset of the tool 320.

[0026] As can be seen from the above, the tube clamping area formed in the tube clamping device 200 is opened, and the tube body to be turned is inserted into the tube clamping area. When working, the transmission sleeve 110 in the rotating device 100 rotates, and drives the tube clamping device 200 to rotate together with the tube body. The linear drive in the processing device drives the movable seat 337 to move into the tube body, and the tool 320 on the adjustment seat 331 is used to turn and clean the inner wall of the tube body. When the linear drive drives the movable seat 337 to move in a direction close to or away from the tube clamping area, that is, drives the movable seat 337 to move axially in the tube body, the positioner on the adjustment seat 331 can detect the offset value between the tool 320 and the axis of the transmission sleeve 110. When the tool 320 moves along the axial direction of the pipe body and deviates from the axis of the transmission sleeve 110, the adjustment seat 331 can move along the radial direction of the pipe body according to the offset value, thereby compensating for the offset error caused by the bending deformation of the linear drive due to the excessive length of the tool 320 during movement, and effectively ensuring the coaxiality of the tool 320 with the pipe body when it moves in the pipe body. In this way, the displacement of the tool 320 fed to the inner wall of the pipe body is adjusted in real time, thereby ensuring the accuracy of the inner wall processing of the pipe body, and realizing automatic cleaning of the inner wall of the pipe body, completing the precision turning of the pipe body, which is particularly suitable for cleaning the crystal layer formed inside the water supply and drainage pipes such as the mesh bag pipe, and realizing the reuse of the pipe after turning.

[0027] The linear drive is mainly used to drive the tool 320 to reciprocate in the tube body. There are many structural forms. For example, the linear drive can be a cylinder, a hydraulic cylinder or an electric guide rail. In this embodiment, Figures 1 to 3 As shown, the linear drive includes a mounting seat 332, a first motor 333, an outer sleeve 334 and a screw 336. The first motor 333 and the outer sleeve 334 are respectively connected to the mounting seat 332. The screw 336 is rotatably connected to the mounting seat 332. The screw 336 is located in the outer sleeve 334. The first motor 333 is transmission-connected to the screw 336. The output shaft of the first motor 333 can be directly driven to be connected to the end of the screw 336 to drive the screw 336 to rotate, or the output shaft of the first motor 333 is engaged with the end of the screw 336 through gears. Transmission, thereby realizing the transmission connection between the two, the movable seat 337 is threadedly connected with the screw rod 336, the movable seat 337 is slidably connected in the outer sleeve 334, the outer side of the movable seat 337 and the inner side of the outer sleeve 334 can be slidably matched through slide rails and slide grooves, the outer side of the outer sleeve 334 is provided with an avoidance slot 335, the avoidance slot 335 extends along the axial direction of the outer sleeve 334, the adjustment seat 331 extends out of the outer sleeve 334 from the avoidance slot 335, the aligner and the tool 320 are respectively connected to the position where the adjustment seat 331 extends out of the outer sleeve 334.

[0028] In this linear actuator, when in use, the tube body that needs to be turned and cleaned can be sleeved on the outside of the outer sleeve 334. The outer sleeve 334 can surround and protect the screw 336 to reduce the exposure of the structure. The positioner and the tool 320 are connected to the position where the adjustment seat 331 extends out of the outer sleeve 334 to better protect the transmission structure. The outer sleeve 334 and the screw 336 both extend in the tube body and can provide support for the axial movement of the movable seat 337 in the tube body. When it is necessary to control the movement of the tool 320, the first motor 333 works to drive the screw 336 to rotate. Since the movable seat 337 is threadedly connected to the screw 336 The movable seat 337 is slidably connected to the outer sleeve 334. As the screw 336 rotates, the movable seat 337 can be driven to slide axially in the outer sleeve 334. Since the outer sleeve 334 and the screw 336 are relatively long, it is difficult to ensure the straightness of the outer sleeve 334 and the screw 336. Therefore, the offset value between the axial movement of the tool 320 along the tube body and the axis of the transmission sleeve 110 is detected by the positioner, so that the displacement of the tool 320 feeding toward the inner wall of the tube body is adjusted in real time to compensate for the downward bending deformation of the outer sleeve 334 and the screw 336 due to gravity, thereby ensuring the accuracy of the processing of the inner wall of the tube body.

[0029] In the above embodiment, if only one end of the outer sleeve 334 is connected to the mounting seat 332 for support, the support stability of the outer sleeve 334 is poor. Since the tube body needs to be sleeved to the outside of the outer sleeve 334, it is difficult to add a support structure at the middle position of the outer sleeve 334. Support can be provided at the end position of the outer sleeve 334. Specifically, the present invention also includes a first support frame 410 and a second support frame 420. The first support frame 410 is surrounded to form a first support area, and the second support frame 420 is surrounded to form a second support area. The two ends of the outer sleeve 334 extend into the first support area and the second support area respectively. The first support area formed by the first support frame 410 and the second support area formed by the second support frame 420 are used to support and position the two ends of the outer sleeve 334 respectively, effectively reducing the situation that the outer sleeve 334 is bent under pressure at the end position, and improving the stability of the movable seat 337 when sliding in the outer sleeve 334.

[0030] In actual application, a sliding sleeve is installed on the first support frame 410, and the sliding sleeve is used to form a first support area to provide support for the outer sleeve 334. A plurality of support wheels are installed in the second support frame 420, and a second support area is formed between the plurality of support wheels. The plurality of support wheels are respectively used to abut against the outer end position of the outer sleeve 334 to provide support and positioning for the outer sleeve 334.

[0031] In order to facilitate the insertion of the tube body into the outside of the outer sleeve 334 and connect it to the tube clamping area of ​​the tube clamping device 200, the present invention also includes a base 510, which is located on the side of the first support frame 410 away from the second support frame 420, and the mounting seat 332 is slidably connected to the base 510. A translation driver 520 is arranged between the mounting seat 332 and the base 510, and the translation driver 520 can drive the mounting seat 332 to slide in a direction close to or away from the second support frame 420. When it is necessary to load and unload the tube body, the translation driver 520 can be used to drive the mounting seat 332 to slide on the base 510 in a direction away from the second support frame 420. At this time, the outer sleeve 334 and the screw 336 can be driven to leave the second support frame 420, so that a space is formed between the first support frame 410 and the second support frame 420 into which the tube body can be directly placed. In this way, the tube body can be easily assembled and disassembled from the tube clamping area, and then the translation driver 520 drives the mounting seat 332 to slide in a direction close to the second support frame 420, and the outer sleeve 334 and the screw 336 are inserted into the tube body, so that the tool 320 can be used to turn and clean the inner wall of the tube body that needs to be processed.

[0032] The translation driver 520 is mainly used to provide a driving force for the mounting seat 332 to reciprocate along the axial direction of the transmission sleeve 110. It has various structural forms, such as a cylinder, a screw rod or a hydraulic cylinder. Since the outer sleeve 334 needs to move a long distance to avoid the installed tube body, in this embodiment, the translation driver 520 adopts a gear and rack meshing transmission method. Specifically, the translation driver 520 includes a third motor, a first gear and a rack. The third motor is connected to the mounting seat 332. The third motor drives the first gear. The third motor can drive the first gear to rotate. The rack is connected to the base 510. The rack extends in a direction parallel to the axial direction of the transmission sleeve 110. The first gear and the rack are meshed with each other. When the mounting seat 332 needs to slide on the base 510, the third motor drives the first gear to rotate forward or reverse, so that the mounting seat 332 can slide on the base 510 in a direction close to or away from the second support frame 420.

[0033] The aligner is mainly used to detect the distance between the tool 320 and the axis of the transmission sleeve 110. In this embodiment, the aligner includes a receiving plate 311 and a laser emitter 312. The receiving plate 311 is provided at at least one side of the movable path of the movable seat 337, and the laser emitter 312 is connected to the position of the adjusting seat 331 corresponding to the receiving plate 311. When the outer sleeve 334 or the screw 336 is deformed, the movable seat 337 moves to the deformed position, which causes the position of the tool 320 feeding to the pipe body to shift. At this time, the emitter on the adjusting seat 331 shifts to the emission point of the receiving plate 311. According to the position where the receiving plate 311 receives the laser, the offset value between the tool 320 and the axis of the transmission sleeve 110 can be obtained. The adjusting seat 331 performs radial activity compensation according to the offset value to achieve precise processing of the inner wall of the pipe body.

[0034] The feed regulator needs to control the radial movement of the adjustment seat 331 to adjust the feeding direction of the tool 320. The feed regulator can control the adjustment seat 331 by directly driving the adjustment seat 331 to move radially along the tube body. In this case, the radial space required by the feed regulator is large, which is not conducive to the use of tubes with smaller diameters. Therefore, in order to reduce the installation space required for the feed regulator, the transmission method of the adjustment seat 331 can be adjusted. Specifically, the feed regulator includes an adjusting screw 361 and an adjusting rod 362. The adjusting screw rod 361 is connected to the movable seat 337, and the adjusting screw rod 361 drives the adjusting rod 362. The adjusting screw rod 361 can drive the adjusting rod 362 to move in a direction away from or close to the transmission sleeve 110. A guide section 363 is formed on the adjusting rod 362 and extends obliquely in a direction away from the axis of the transmission sleeve 110. The adjusting seat 331 is connected to the movable seat 337 along the radial sliding direction of the transmission sleeve 110, and the guide section 363 is inserted into the adjusting seat 331. The adjusting screw 361 adjusts the position of the adjusting rod 362 along the axial movement of the tube body, which can reduce the radial installation space requirement of the adjusting screw 361 and the adjusting rod 362 in the outer sleeve 334, so that the driving source that drives the adjusting seat 331 to move is compactly installed in the outer sleeve 334. When it is necessary to increase the feeding depth of the tool 320 into the tube body, the adjusting screw 361 drives the adjusting rod 362 to move closer to the adjusting seat 331. Since the guide section 363 on the adjusting rod 362 is inclined in the direction away from the axis of the transmission sleeve 110, the guide section 363 can guide the adjusting seat 331 so that the tool 320 on the adjusting seat 331 moves further closer to the inner wall of the tube body. When it is necessary to reduce the feeding depth of the tool 320 into the tube body, the adjusting screw 361 drives the adjusting rod 362 to move in the direction away from the adjusting seat 331. Similarly, the guiding section 363 guides the adjusting seat 331 so that the tool 320 on the adjusting seat 331 moves in the direction away from the inner wall of the tube body, so that the tool 320 can be driven to move and adjust in the radial direction.

[0035] The rotating device 100 has a driving source for driving the transmission sleeve 110 to rotate. Specifically, Figure 4 As shown, the rotating device 100 includes a base frame 120 and a second motor 130. A fixing sleeve 140 is connected to the base frame 120. The transmission sleeve 110 is rotatably connected in the fixing sleeve 140. The second motor 130 is connected to the base frame 120. The second motor 130 is in transmission connection with the transmission sleeve 110. In practical applications, the output shaft of the second motor 130 and the end of the transmission sleeve 110 can be driven by gear meshing, so that the second motor 130 is used to drive the transmission sleeve 110 to rotate. In order to avoid the outer sleeve 334, the middle part of the second gear has an avoidance hole for the outer sleeve 334 to pass through. The transmission sleeve 110 is rotatably installed in the fixing sleeve 140, which can improve the stability of the installation of the transmission sleeve 110. When working, the second motor 130 provides a rotational driving force to the transmission sleeve 110, driving the transmission sleeve 110 to rotate, thereby driving the tube body to rotate through the tube clamping device 200.

[0036] The pipe clamping device 200 provides an openable and closable pipe clamping area, thereby clamping or loosening the pipe body. There are various structural forms. For example, the pipe clamping device 200 is a clamp installed on the transmission sleeve 110. In order to improve the convenience of clamping the pipe body, in this embodiment, the pipe clamping device 200 is a three-jaw chuck. The three-jaw chuck has three claws that can move away from or close to each other, and an openable and closable pipe clamping area is formed between the three claws. When the three claws move away from each other, the pipe clamping area is opened, and the pipe body can be loaded or unloaded. When the three claws move close to each other, the pipe clamping area is closed to clamp the pipe body.

[0037] The present invention also includes a limiting frame 610, wherein a plurality of limiting wheels 620 are arranged in a circular array around the axis of the transmission sleeve 110, and a limiting area is formed between the plurality of limiting wheels 620, and the limiting area is directly opposite to the tube clamping area. Naturally, in order to allow the tube body to rotate smoothly in the limiting area, the rotation axes of the plurality of limiting wheels 620 are parallel to the rotation axis of the tube body, so that the plurality of limiting wheels 620 limit the outside of the tube body while reducing the rotational friction with the tube body. When the tube body is loaded, the tube body can enter the limiting area, and the plurality of limiting wheels 620 are used to abut against the outer wall of the tube body to provide support for the tube body. In this way, the limiting frame 610 is used to provide support for the outside of the tube body, which can improve the stability of the rotation of the tube body. In practical applications, the limiting frame 610 includes a fixed portion, a rotating portion rotatably connected to the fixed portion, the rotating portion can be rotated to close in a direction close to the fixed portion, or rotated to open in a direction away from the fixed portion, and the rotating portion and the fixed portion are respectively connected with a limiting wheel 620. When the tube body needs to be placed, the rotating portion can be rotated open from the fixed portion, at which time the limiting area is opened, and the tube body can be conveniently placed, and then the rotating portion is rotated toward the fixed portion to close, and the rotating portion and the fixed portion are fastened by screws, buckles, etc., so that the tube body is limited in the limiting area. In addition, the position of the limiting wheel 620 on the limiting frame 610 can be fixed, or an adjustment structure such as a hand screw is installed on the limiting frame 610, and the limiting wheel 620 is installed on the hand screw. The position of the limiting wheel 620 can be adjusted by the hand screw, thereby adjusting the size of the limiting area formed by the enclosure.

[0038] Furthermore, a plurality of the limiting frames 610 are arranged at intervals in a direction away from the clamping area, and the number of the limiting frames 610 can be set according to the length of the tube body. When the length of the tube body is longer, the number of the limiting frames 610 is more. For example, the number of the limiting frames 610 can be two or three. The plurality of limiting frames 610 can provide support at different positions of the tube body, effectively preventing the tube body from bending downward due to being too long, and further improving the stability of the tube body rotation.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
