Description

Technical Field

[0001] This application belongs to the field of drilling construction technology, specifically relating to a hand-held pneumatic drill assembly integrated into a drilling rig. Background Technology

[0002] A hand-held rock drill is a common drilling tool, while a drill rig is a platform device that supports the hand-held rock drill for drilling in rock. When the two are combined, the hand-held rock drill is set on the working surface of the drill rig and has the freedom to move along the working surface to adjust and fix different drilling positions.

[0003] In traditional operation modes, the position of a hand-held pneumatic drill relative to the working face needs to be adjusted manually. However, the inventors discovered that manual adjustment has problems such as large positioning errors, time-consuming installation, and low safety, which affect the overall efficiency of drilling operations. Utility Model Content

[0004] This application provides a hand-held pneumatic drill assembly integrated into a drill rig carriage, which aims to flexibly adjust the relative position of the hand-held pneumatic drill with respect to the drill rig carriage in order to ensure the overall efficiency of drilling operations.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] A hand-held pneumatic drill assembly integrated into a drill rig carriage is provided, including a mounting plate for fixing it to the drill rig carriage; the hand-held pneumatic drill assembly further includes:

[0007] A swing plate is hinged to the mounting plate in a horizontal direction; the swing plate has a vertical state and a horizontal state, and has a vertical locking structure and a horizontal locking structure with the mounting plate; a turntable is rotatably mounted on the swing plate, and the turntable is driven by a rotation drive component.

[0008] A slider is disposed on the side of the turntable facing away from the swing plate, and is slidably connected to the turntable radially therefrom, with a sliding position locking structure between the slider and the turntable; a turntable is rotatably connected to the slider; and

[0009] The hand drill body is hinged horizontally to the turntable; the hand drill body has a drill rod rotatably connected to it for drilling into the wall, and the drill rod and the swing plate have an orientation locking structure.

[0010] In one possible implementation, the orientation bit locking structure includes:

[0011] A base plate is fixedly connected to the swing plate and is located on the same side of the swing plate as the turntable; a lower strip groove is provided on the end face of the base plate facing away from the swing plate, and the lower strip groove is provided to penetrate the base plate along the thickness direction of the base plate;

[0012] A cover plate, hinged to the end face of the base plate facing away from the swing plate, and having an upper strip groove thereon; a swing position locking structure exists between the cover plate and the base plate, which connects the base plate and the cover plate when the cover plate swings to abut against the base plate, and the upper and lower strip grooves communicate to form a strip hole extending parallel to the hinge axis of the swing plate; and

[0013] A sleeve is inserted into the strip hole, and its two ends abut against the two sides of the base plate facing its own thickness direction and the two sides of the cover plate facing its own thickness direction, respectively; the sleeve is adapted to be fitted around the outer periphery of the drill rod so that the drill rod has a degree of freedom to move relative to the swing plate along the length direction of the strip hole, and a degree of freedom to move relative to the sleeve along the axial direction of the sleeve.

[0014] In one possible implementation, the swing position locking structure includes:

[0015] A positioning block with a slot is fixedly mounted on the base plate, with the slot facing upwards; and

[0016] A latch is slidably disposed on the swing end face of the cover plate;

[0017] When the cover plate swings to abut against the base plate, the sliding direction of the pin is parallel to the up-down direction, so that the pin is suitable for insertion into the slot and the swing of the cover plate relative to the base plate is restricted.

[0018] In one possible implementation, a slide rail extending radially is fixedly mounted on the turntable, and the slider has a protrusion that slidably engages within the slide rail; the sliding position locking structure includes:

[0019] A positioning threaded groove is formed on the protrusion;

[0020] Multiple through holes are formed on the slide rail, spaced apart along the length of the slide rail, and all are adapted to coaxially communicate with the positioning threaded groove; and

[0021] A butt bolt, adapted to be inserted into either of the through holes and adapted to be threadedly connected to the positioning threaded groove to restrict the movement of the slider relative to the turntable.

[0022] In one possible implementation, an elastic drive member is further provided between the turntable and the slider. The elastic drive member is fixedly disposed on the turntable and connected to the side of the slider facing the central axis of the turntable, so as to drive the slider to move away from the central axis of the turntable.

[0023] In one possible implementation, the outer circumferential surface of the turntable has a plurality of spaced-apart toothed grooves, and the rotation drive component includes:

[0024] A transmission gear is rotatably mounted on the swing plate and meshes with the tooth groove; and

[0025] The rotating motor is fixedly mounted on the swing plate and is connected to the transmission gear.

[0026] In one possible implementation, a rotational locking structure is provided between the hand drill body and the slider;

[0027] When the swing plate is in the vertical state, the rotation position locking structure can connect the hand drill body and the slider, and make the turntable and the slider connected to restrict the rotation of the turntable relative to the slider, and restrict the swing of the hand drill body relative to the turntable.

[0028] In one possible implementation, the hand drill body is hinged to the turntable via a coupling; the rotation position locking structure includes:

[0029] A shaped groove is formed on the outer end face of the coupling; and

[0030] The alignment arm is rotatably connected to the outer side of the slider and has the freedom to move toward and away from the slider; the alignment arm has a limiting block on the side facing the slider and the limiting block is adapted to be embedded in the irregular groove.

[0031] When the limiting block is embedded in the irregular groove, it can restrict the rotation of the connecting shaft to limit the swing of the hand drill body; and the side of the alignment arm facing the slider abuts against the outer side of the turntable to limit the rotation of the turntable relative to the slider.

[0032] The bottom of the irregular groove is made of magnetic material, and the limiting block is made of a corresponding material suitable for magnetic attraction with the magnetic material.

[0033] In one possible implementation, the end of the swing plate that connects to the mounting plate has a bent portion, and the bent portion is hinged to the mounting plate;

[0034] The vertical locking structure includes:

[0035] An upper limit plate is rotatably connected to the upper side of the mounting plate in the vertical direction; and

[0036] A lower limit plate is disposed on the lower side of the mounting plate and is connected to the mounting plate;

[0037] When the swing plate is in the vertical state, the upper limit plate can rotate to a blocking state that abuts against the upward side of the bend, and can also rotate to an idle state that avoids the bend; at the same time, the lower limit plate can abut against the downward side of the bend, so as to cooperate with the upper limit plate in the blocking state to limit the swing of the swing plate.

[0038] In one possible implementation, the horizontal bit locking structure includes:

[0039] Alignment threaded grooves are formed on the outer surface of the mounting plate; and

[0040] The positioning arm is hinged to the swing plate in the horizontal direction, and its swing end has a positioning hole, and a locking bolt for threaded connection with the alignment thread groove is inserted into the positioning hole.

[0041] When the swing plate is in the horizontal state, the positioning arm can rotate to the position where the positioning hole communicates with the alignment thread groove, so as to limit the swing of the swing plate relative to the mounting plate through the threaded connection of the locking bolt and the alignment thread groove.

[0042] In actual use, the hand drill assembly provided in this embodiment has two different usage states:

[0043] First, the swing plate swings to a horizontal position and is locked by connecting the swing plate and the mounting plate through a horizontal locking structure.

[0044] In this state, the connection between the slider and the turntable, formed by the sliding position locking structure, is released, meaning the slider has the freedom to move relative to the turntable. Simultaneously, the drill rod of the hand drill body, influenced by the orientation locking structure, remains parallel to the horizontal plane and perpendicular to the hinge axis of the swing plate. By moving the drill chuck, the drill rod can extend to the outside of the mounting plate and contact the machining surface, thus completing the drilling operation.

[0045] During drilling operations, the rotary drive component rotates the turntable, causing the slider to move synchronously along the turntable's circumference. During this synchronous movement, the distance between the slider and the turntable's central axis can be manually adjusted to compensate for changes in the distance between the slider and the machining surface. Simultaneously, due to the orientation locking structure, the drill rod maintains contact with the machining surface, and the drill rod possesses the freedom to rotate horizontally to the machining surface. This achieves the technical objective of adjusting the relative position of the drill rod and the machining surface in the horizontal direction, making it suitable for drilling along straight trajectories.

[0046] Secondly, the swing plate swings to a vertical position and is locked by connecting the swing plate and the mounting plate through a vertical locking structure.

[0047] In this state, the connection between the drill rod and the swing plate, which is formed by the orientation locking structure, is released. The sliding locking structure can keep the distance between the slider and the central axis of the turntable constant. At the same time, the drill rod can maintain contact with the machining surface under the combined action of manual control and the directional movement of the drill rig, thereby completing the drilling operation.

[0048] During drilling, the rotating drive component drives the turntable to rotate, which in turn causes the slider to move synchronously along the circumference of the turntable. This allows the processing position to move along a circular trajectory, achieving the technical objective of adjusting the relative position of the drill rod and the processing surface along a circumferential direction. This method is suitable for drilling operations along a circular trajectory.

[0049] The hand-held pneumatic drill assembly integrated into the drill chuck carriage provided in this embodiment, compared with the prior art, can flexibly adjust the relative position of the hand-held pneumatic drill to the drill chuck carriage, so as to ensure the overall efficiency of drilling construction.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0069] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0070] Please refer to the following: Figures 1 to 14 The present application will now describe the hand drill assembly integrated into the drill rig carriage. The hand drill assembly integrated into the drill rig carriage proposed in this application includes a mounting plate 10, a swing plate 1, a slider 2, and a hand drill body 3.

[0071] Mounting plate 10 is used for fixed mounting on the drilling rig trolley; in actual design, a horizontal working surface of the drilling rig trolley can also be used as mounting plate 10. Based on this, the structures mentioned in this embodiment all have detachable connection properties to be suitable for structural modification of existing drilling rig trolleys.

[0072] The swing plate 1 is hinged to the mounting plate 10 in the horizontal direction, specifically at one end of the mounting plate 10 near the machined surface. In actual use, the swing plate 1 has a vertical state where its outer surface is parallel to the vertical direction, and a horizontal state where its outer surface is parallel to the horizontal direction.

[0073] To ensure that the swing plate 1 can be stably positioned in both vertical and horizontal states, a vertical locking structure 4 and a horizontal locking structure 5 are provided between the swing plate 1 and the mounting plate 10. Specifically, the vertical locking structure 4 connects the swing plate 1 in a vertical state and the mounting plate 10, so that the swing plate 1 is always in a vertical state. The horizontal locking structure 5 connects the swing plate 1 in a horizontal state and the mounting plate 10, so that the swing plate 1 is always in a horizontal state.

[0074] A turntable 12 is rotatably connected to the outer side of the swing plate 1, and the turntable 12 is driven by a rotation drive member 13 for rotating relative to the swing plate 1. Based on this, when the swing plate 1 is in a horizontal state, the side of the turntable 12 facing away from the swing plate 1 (i.e., the outer side of the turntable 12) is facing upward; when the swing plate 1 is in a vertical state, the side of the turntable 12 facing away from the swing plate 1 is facing horizontally (in this embodiment, the side of the turntable 12 facing away from the swing plate 1 is facing the processing surface).

[0075] The slider 2 is disposed on the side of the turntable 12 facing away from the swing plate 1, and is slidably connected to the turntable 12 radially to allow the slider 2 to move toward or away from the central axis of the turntable 12. A sliding position locking structure 6 is provided between the slider 2 and the turntable 12 to connect the slider 2 and the turntable 12, thereby restricting the movement of the slider 2 relative to the turntable 12.

[0076] Based on the foregoing, a turntable 21 is rotatably connected to the end face of the slider 2 facing away from the turntable 12. The rotation axis of the turntable 21 is parallel to the arrangement direction of the slider 2 and the turntable 12, so that the turntable 21 can rotate relative to the slider 2.

[0077] The hand drill body 3 is horizontally hinged to the end face of the turntable 21 facing away from the slider 2; based on this, the hand drill body 3 has a drill rod 31 rotatably connected to it for drilling into the wall (under the action of the internal drive accessories of the hand drill body 3).

[0078] The drill rod 31 and the oscillating plate 1 have an orientation locking structure 7. The orientation locking structure 7 connects the drill rod 31 and the oscillating plate 1 to restrict the axial direction of the drill rod 31 and ensure that the axial and horizontal directions of the drill rod 31 are parallel and perpendicular to the machining surface. Based on this, when the oscillating plate 1 is in a horizontal state and the drill rod 31 moves in the horizontal direction, the orientation locking structure 7 can restrict the oscillation of the drill rod 31, so that the drill rod 31 translates in a horizontal direction, thereby realizing the drilling operation on the machining surface.

[0079] In actual use, the hand drill assembly provided in this embodiment has two different usage states:

[0080] First, the swing plate 1 swings to a horizontal state and is locked by connecting the swing plate 1 and the mounting plate 10 through the horizontal locking structure 5.

[0081] In this state, the connection between the slider 2, which is formed by the sliding position locking structure 6, and the turntable 12 is released, meaning that the slider 2 has the freedom to move relative to the turntable 12. At the same time, the drill rod 31 of the hand drill body 3 is kept parallel to the horizontal plane and perpendicular to the hinge axis of the swing plate 1 by the orientation locking structure 7. By moving the drill chuck trolley, the drill rod 31 can be extended to one end outside the mounting plate 10 to contact the machining surface, thereby completing the drilling operation.

[0082] During drilling operations, the rotating drive component 13 drives the turntable 12 to rotate, which in turn causes the slider 2 to move synchronously along the circumference of the turntable 12. During the synchronous movement of the slider 2, the distance between the slider 2 and the central axis of the turntable 12 can be manually adjusted to compensate for changes in the distance between the slider 2 and the machining surface. At the same time, due to the limiting effect of the orientation locking structure 7, the drill rod 31 can maintain contact with the machining surface, and the drill rod 31 has the freedom to move horizontally corresponding to the machining surface. This achieves the technical purpose of adjusting the relative position of the drill rod 31 and the machining surface in the horizontal direction, and is suitable for drilling operations on a straight trajectory.

[0083] Secondly, the swing plate 1 swings to a vertical position and is locked by connecting the swing plate 1 and the mounting plate 10 through the vertical position locking structure 4.

[0084] In this state, the connection between the drill rod 31 and the swing plate 1 is released by the orientation locking structure 7, and the distance between the slider 2 and the central axis of the turntable 12 can be kept constant by the sliding locking structure 6; at the same time, the drill rod 31 can maintain contact with the processing surface under the combined action of manual control and the directional movement of the drill rig trolley, thereby completing the drilling operation.

[0085] During the drilling process, the rotating drive component 13 drives the turntable 12 to rotate, which causes the slider 2 to move synchronously along the circumference of the turntable 12. This allows the processing position to move along a circular trajectory, achieving the technical purpose of adjusting the relative position of the drill rod 31 and the processing surface along a circumferential direction. This method is suitable for drilling operations along a circumferential trajectory.

[0086] The hand-held pneumatic drill assembly integrated into the drill chuck carriage provided in this embodiment, compared with the prior art, can flexibly adjust the relative position of the hand-held pneumatic drill to the drill chuck carriage, so as to ensure the overall efficiency of drilling construction.

[0087] In some embodiments, such as Figure 2 and Figure 7 As shown, the orientation locking structure 7 includes a base plate 71, a cover plate 72, and a rod sleeve 73.

[0088] The base plate 71 is fixedly connected to the swing plate 1 and is located on the same side of the swing plate 1 as the turntable 12. A lower strip groove 711 is provided on the end face of the base plate 71 facing away from the swing plate 1, and the lower strip groove 711 is provided through the base plate 71 along the thickness direction of the base plate 71.

[0089] The cover plate 72 is hinged to the end face of the base plate 71 facing away from the swing plate 1 by a hinge, and an upper strip groove 721 is provided on it.

[0090] The cover plate 72 and the base plate 71 have a swing position locking structure 8. When the cover plate 72 swings to abut the base plate 71, the swing position locking structure 8 can connect the base plate 71 and the cover plate 72 to limit the swing of the cover plate 72 relative to the base plate 71. At the same time, the upper strip groove 721 and the lower strip groove 711 are connected to form a strip hole extending in the direction parallel to the hinge axis of the swing plate 1.

[0091] The sleeve 73 is inserted into the aforementioned strip hole, and both ends of it have limiting discs extending outward along their own radial direction. When the swing position locking structure 8 connects the base plate 71 and the cover plate 72, and the sleeve 73 is inserted into the strip hole, the limiting discs at both ends abut against the two sides of the base plate 71 facing its own thickness direction, and the two sides of the cover plate 72 facing its own thickness direction, respectively.

[0092] In actual use, the sleeve 73 is adapted to be fitted around the outer periphery of the drill rod 31 so that the drill rod 31 has the degree of freedom to move relative to the swing plate 1 along the length direction of the strip hole, and the degree of freedom to move relative to the sleeve 73 along the axial direction of the sleeve 73.

[0093] In some embodiments, such as Figure 8 As shown, the swing position locking structure 8 includes a positioning block 81 and a pin 82.

[0094] The positioning block 81 is fixedly mounted on the base plate 71 and has an upward-facing slot 811.

[0095] The pin 82 is slidably disposed on the swing end face of the cover plate 72.

[0096] By adopting the above technical solution, when the cover plate 72 swings to abut against the base plate 71, the sliding direction of the pin 82 is parallel to the up and down direction, so that the pin 82 is inserted into the slot 811 downward under its own weight, thereby limiting the swing of the cover plate 72 relative to the base plate 71.

[0097] It should be noted that, in order to improve the stability of the pin 82 and the positioning block 81 when they are assembled, the outer side of the positioning block 81 is also provided with a horizontal hole that communicates with the slot 811, and the pin 82 has an elastic protrusion that is suitable for being embedded in the horizontal hole, so as to prevent the pin 82 and the positioning block 81 from separating under non-human force.

[0098] In some embodiments, such as Figure 9 , Figure 11 and Figure 12 As shown, a slide rail 121 extending radially is fixedly provided on the turntable 12, and the slider 2 has a protrusion 22 that is slidably engaged in the slide rail 121.

[0099] Based on this, in this embodiment, the sliding position locking structure 6 includes a positioning threaded groove 61, multiple through holes 62, and a mating bolt 63.

[0100] The positioning threaded groove 61 is formed on the protrusion 22.

[0101] Multiple through holes 62 are provided on the slide rail 121, spaced apart along the length of the slide rail 121, and are all suitable for coaxial communication with the positioning threaded groove 61.

[0102] The mating bolt 63 is adapted to be inserted into either of the through holes 62 and to be threaded into the positioning threaded groove 61 to restrict the movement of the slider 2 relative to the turntable 12.

[0103] In some embodiments, such as Figure 11 As shown, there is also an elastic drive member 123 between the turntable 12 and the slider 2. This elastic drive member 123 is fixedly mounted on the turntable 12 and connected to the side of the slider 2 facing the central axis of the turntable 12, so as to drive the slider 2 to move away from the central axis of the turntable 12.

[0104] It should be further explained that, in this embodiment, the turntable 12 has a guide rod fixedly connected to it on its outer side, and the slider 2 is slidably connected to this guide rod. Based on this, the elastic drive component 123 is a spring sleeved on the guide rod, and the two ends of this spring are respectively connected to the turntable 12 and the slider 2 to realize the elastic drive of the slider 2 and ensure that the end of the aforementioned drill rod 31 contacts the machining surface.

[0105] In some embodiments, such as Figures 9 to 11 As shown, the outer circumferential surface of the turntable 12 has a plurality of spaced toothed grooves 122. Based on this, in this embodiment, the rotation drive component 13 includes a transmission gear 131 and a rotation motor 132.

[0106] The transmission gear 131 is rotatably mounted on the swing plate 1 and meshes with the tooth groove 122 to achieve synchronous rotation with the turntable 12.

[0107] The rotating motor 132 is fixedly mounted on the swing plate 1 and is connected to the transmission gear 131.

[0108] It should be further explained that the outer surface of the swing plate 1 has a recessed groove, in which the turntable 12 is rotatably fitted; similarly, the transmission gear 131 is recessed and installed on the outside of the recessed groove, and the meshing relationship between the transmission gear 131 and the tooth groove 122 is ensured by connecting the corresponding groove and the recessed groove. In addition, to prevent dust from entering the recessed groove, and to prevent dust from adhering to the tooth groove 122 and the transmission gear 131, the swing plate 1 is also provided with a sealing ring that can fill the gaps between the components.

[0109] In some embodiments, such as Figures 12 to 14 As shown, there is a rotation position locking structure 9 between the hand drill body 3 and the slider 2.

[0110] By adopting the above technical solution, when the swing plate 1 is in a vertical state, the aforementioned rotation position locking structure 9 can connect the hand drill body 3 and the slider 2, and make the turntable 21 and the slider 2 connected, so as to restrict the rotation of the turntable 21 relative to the slider 2, and at the same time restrict the swing of the hand drill body 3 relative to the turntable 21.

[0111] In some embodiments, such as Figures 12 to 14 As shown, the hand drill body 3 is hinged to the turntable 21 via a connecting shaft 32; specifically, the turntable 21 has two side arms on its upper side; the hand drill body 3 is positioned between the two side arms, and each side facing the two side arms has a connecting shaft 32. The two connecting shafts 32 are coaxially arranged and pass through the two side arms respectively, so as to realize the hinge connection between the hand drill body 3 and the turntable 21.

[0112] Based on this, in this embodiment, the rotation locking structure 9 includes a shaped groove 91 and an alignment arm 92.

[0113] The irregular groove 91 is formed on the outer end face of the connecting shaft 32.

[0114] The alignment arm 92 is rotatably connected to the outer side of the slider 2 and has the freedom to move toward and away from the slider 2; and the alignment arm 92 has a limiting block 921 on the side facing the slider 2, and the limiting block 921 is adapted to be embedded in the irregular groove 91.

[0115] In actual use, by rotating the alignment arm 92, the limiting block 921 can be positioned towards the irregular groove 91; at this time, moving the alignment arm 92 towards the connecting shaft 32 allows the limiting block 921 to be inserted into the irregular groove 91. When the limiting block 921 is embedded in the irregular groove 91, it can restrict the rotation of the connecting shaft 32, thereby restricting the swing of the hand drill body 3; and the side of the alignment arm 92 facing the slider 2 abuts against the outer side of the turntable 21, thereby restricting the rotation of the turntable 21 relative to the slider 2.

[0116] In order to prevent the limiting block 921 from detaching from the irregular groove 91, in this embodiment, the bottom of the irregular groove 91 is made of magnetic material, and the limiting block 921 is made of a corresponding material suitable for magnetic attraction with the magnetic material.

[0117] In some embodiments, such as Figure 4 and Figure 5 As shown, the end of the swing plate 1 that connects to the mounting plate 10 has a bent portion 11, and this bent portion 11 is hinged to the mounting plate 10 to achieve the hinge connection between the swing plate 1 and the mounting plate 10. Based on this, when the swing plate 1 is in a horizontal state, due to the presence of the bent portion 11, there is a gap between the downward-facing side of the swing plate 1 and the upper side of the mounting plate 10; at the same time, the downward-facing side of the swing plate 1 has an elastic pad that can contact the mounting plate 10.

[0118] The vertical locking structure 4 includes an upper limit plate 41 and a lower limit plate 42.

[0119] The upper limit plate 41 is rotatably connected to the upper side of the mounting plate 10 in the vertical direction.

[0120] The lower limit plate 42 is located on the lower side of the mounting plate 10 and is connected to the mounting plate 10.

[0121] When the swing plate 1 is in a vertical state, the upper limit plate 41 can rotate to a blocking state that abuts against the upward side of the bent part 11, and can also rotate to an idle state that avoids the bent part 11; at the same time, the lower limit plate 42 can abut against the downward side of the bent part 11, so as to cooperate with the upper limit plate 41 in the blocking state to clamp the bent part 11, thereby limiting the swing of the swing plate 1.

[0122] In some embodiments, such as Figure 6 As shown, the horizontal locking structure 5 includes an alignment threaded groove 51 and a positioning arm 52.

[0123] The alignment thread groove 51 is formed on the outer side of the mounting plate 10, specifically on the side of the mounting plate 10 facing the hinge axis of the swing plate 1.

[0124] The positioning arm 52 is hinged to the swing plate 1 in a horizontal direction, and its hinge axis is parallel to the hinge axis of the swing plate 1. The swing end of the positioning arm 52 has a positioning hole 521 that extends along its hinge axis, and a locking bolt 522 that can be threaded into the positioning hole 521 is inserted into the positioning hole 521.

[0125] When the swing plate 1 is in a horizontal state, the positioning arm 52 can be rotated to the position where the positioning hole 521 communicates with the alignment thread groove 51 by manual movement; then, the swing of the swing plate 1 relative to the mounting plate 10 can be restricted by the threaded connection between the locking bolt 522 and the alignment thread groove 51, so as to achieve the stability of the swing plate 1 in a horizontal state.

[0126] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
