Description

Technical Field

[0001] This application relates to the field of packaging equipment technology, and in particular to a packaging device. Background Technology

[0002] With the development of packaging technology, roll film packaging technology has emerged. This technology involves wrapping a plastic film or other film structure around the outer circumference of a cylinder. When in use, the cylinder is rotated to unwrap the film structure from the outer circumference of the cylinder. This allows the film structure to wrap around the outer circumference of the object to be packaged. As more and more of the film structure unwraps, it can fully wrap around the outer circumference of the object to be packaged, thus completing the packaging.

[0003] In related technologies, packaging devices typically have a pin, with the film roll sleeved around the outer circumference of the pin. During use, the end of the film structure is first fixed to the surface of the item to be packaged. The operator holds the item and manually rotates it, pulling the film structure from the outer circumference of the roll and wrapping it around the item. If the length of the item is greater than the width of the film structure, the operator needs to move the item along the axial direction of the film roll to ensure the film structure fully wraps the item.

[0004] However, the aforementioned method of packaging by manually rotating the items to be packaged is time-consuming, labor-intensive, and inefficient. When the items are large or heavy, it is difficult to rotate them, making the operation cumbersome. Furthermore, the shapes and types of items to be packaged are not entirely the same; some items are easier to package vertically, while others are easier to package horizontally. Because the pin position of the aforementioned packaging device is relatively fixed, the unwinding direction of the film is difficult to adjust, making it impossible to adjust the unwinding direction according to the shape of the item to be packaged. This results in poor adaptability to different shapes of items, leading to difficulties in the packaging operation. Utility Model Content

[0005] Therefore, it is necessary to provide a packaging device that requires no manual operation and can adjust the unwinding direction of the film, in order to address the problems of time-consuming, labor-intensive, and space-constrained manual operations.

[0006] A packaging device comprising:

[0007] frame;

[0008] A fixed rod, one end of which is rotatably connected to the frame;

[0009] A roll film is fitted around the outer periphery of the fixing rod;

[0010] A rotating mechanism is connected to the frame and located on one side of the roll film. The rotating mechanism is used to drive the object to be packaged to rotate, so that the film structure of the roll film is wrapped around the object to be packaged.

[0011] A lifting mechanism is connected to the rotating mechanism and is used to drive the rotating mechanism to move in a predetermined direction.

[0012] In some embodiments, the rotating mechanism includes a support plate and a first driving member, the first driving member being connected to the support plate and used to drive the support plate to rotate.

[0013] In some embodiments, the packaging device further includes two rotating connectors, both of which are coaxially arranged with the fixed rod and respectively abut against both ends of the roll film.

[0014] In some embodiments, the lifting mechanism includes a movable seat, a fixed seat, and a connecting assembly. The fixed seat is connected to the frame, and the movable seat is connected to the fixed seat via the connecting assembly. The connecting assembly is used to adjust the relative distance between the fixed seat and the movable seat. The movable seat is connected to the rotating mechanism.

[0015] In some embodiments, the connecting assembly includes a first link and a second link, the center of the first link being rotatably connected to the center of the second link; the movable seat has a first sliding groove, the fixed seat has a second sliding groove, one end of the first link is engaged with the first sliding groove and moves along the length direction of the first sliding groove, the other end of the first link is rotatably connected to the fixed seat, one end of the second link is engaged with the second sliding groove and moves along the length direction of the second sliding groove, and the other end of the second link is rotatably connected to the movable seat.

[0016] In some embodiments, the lifting mechanism further includes a second drive member, comprising at least one of the following:

[0017] The second driving member is connected to the first connecting rod and is used to drive the end of the first connecting rod to move along the first slide groove;

[0018] The second driving member is connected to the second connecting rod and is used to drive the end of the second connecting rod to move along the second groove.

[0019] In some embodiments, the second driving element is a cylinder.

[0020] In some embodiments, the frame is provided with a rotating seat and a mounting seat, one end of the fixing rod is rotatably connected to the rotating seat, and the other end of the fixing rod is detachably connected to the mounting seat.

[0021] In some embodiments, the packaging device further includes a fixing bolt; the mounting base has a first mounting hole, and the end of the fixing rod connected to the mounting base has a first positioning hole, the first positioning hole and the first mounting hole are correspondingly provided, and the fixing bolt is inserted into the first positioning hole and the first mounting hole.

[0022] In some embodiments, the packaging device further includes a pin; the rotating seat has a second mounting hole, and the end of the fixed rod connected to the rotating seat has a second positioning hole, the second positioning hole and the second mounting hole are correspondingly arranged, and the pin is inserted into the second positioning hole and the second mounting hole.

[0023] In the aforementioned packaging device, the film roll is fitted around the outer periphery of the fixed rod. A rotating mechanism is connected to the frame and positioned on one side of the film roll. When the rotating mechanism drives the object to be packaged to rotate, the object pulls the film roll structure from the roll and wraps around its outer periphery. The rotating mechanism automatically completes the packaging of the object without manual operation, saving time and effort, and is suitable for large and heavy objects. When the length of the object to be packaged is greater than the width of the film roll, the rotating mechanism and the object to be packaged are driven by a lifting mechanism to move in a predetermined direction, which is the axial direction of the film roll. This allows the film roll to fully wrap the object, also without manual operation, saving time and effort. One end of the fixed rod is rotatably connected to the frame, and the film roll rotates with the fixed rod. This allows the unwinding direction of the film roll to be adjusted according to the shape of the object, and the setting direction of the film roll can be adjusted according to the object, facilitating the packaging of objects of different shapes and effectively improving adaptability to various objects.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0033] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as a limitation of this application.

[0034] Furthermore, where the terms "first" and "second" appear, these terms are 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 with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0038] See Figure 1 and Figure 5 , Figure 1 A schematic diagram of the overall structure of the packaging device according to one embodiment of this application is shown. Figure 5 This diagram shows an overall structural schematic of the packaging device according to one embodiment of the present application from another angle. It should be noted that this is for the purpose of illustrating the structure of the fixing rod 200. Figure 1 and Figure 5The diagram shows the structure of the roll film 300 in its disassembled state. One embodiment of this application provides a packaging device including a frame 100, a fixing rod 200, a roll film 300, a rotating mechanism 400, and a lifting mechanism 500. One end of the fixing rod 200 is rotatably connected to the frame 100; the roll film 300 is sleeved on the outer periphery of the fixing rod 200; the rotating mechanism 400 is connected to the frame 100 and located on one side of the roll film 300, and is used to drive the object to be packaged to rotate, so that the film structure of the roll film 300 wraps around the object to be packaged; the lifting mechanism 500 is connected to the rotating mechanism 400 and is used to drive the rotating mechanism 400 to move in a predetermined direction.

[0039] See Figure 1 and Figure 5 The fixed rod 200 is set vertically, and the roll film 300 is sleeved on the outer periphery of the fixed rod 200. The rotating mechanism 400 is set vertically and located to the right of the roll film 300. The object to be packaged is placed on the rotating mechanism 400, which drives the object to be packaged to rotate. The end of the roll film 300 is fixed to the surface of the object to be packaged. When the object to be packaged rotates, the roll film 300 can be pulled to unwind from the roll, and the film structure is wrapped around the outer surface of the object to be packaged for packaging. The frame 100 is assembled from multiple rod-shaped parts. One end of the fixed rod 200 is rotatably connected to the frame 100, so that the fixed rod 200 can rotate around the rotatable connection point with the frame 100. It should be noted that the axis of rotation of the fixed rod 200 relative to the frame 100 passes through the rotatable connection point between the fixed rod 200 and the frame 100 and is perpendicular to the length direction of the fixed rod 200. The film roll 300 rotates relative to the frame 100 with the fixed rod 200, thereby changing the unwinding direction of the film roll 300 to adjust to the shape of the object to be packaged. This allows the film structure of the film roll 300 to wrap around the object at a suitable packaging angle. For ease of understanding, when the fixed rod 200 rotates to a vertical position, the unwinding direction of the film roll 300 is horizontal; when the fixed rod 200 rotates to a horizontal position, the unwinding direction of the film roll 300 is vertical. This adjusts the direction in which the film roll 300 wraps around the object to be packaged. The predetermined direction is the axial direction of the film roll 300 (i.e., the vertical direction). When the length of the object to be packaged is greater than the width of the film roll 300, the lifting mechanism 500 drives the rotating mechanism 400 and the object to be packaged to move vertically, allowing the film structure of the film roll 300 to fully wrap the object.

[0040] It should be noted that, for example, if the width of the roll film 300 is 50cm and the length of the item to be packaged is 100cm, and the item to be packaged is set parallel to the roll film 300, with the roll film 300 wrapped around the outer periphery of the portion of the item below its midpoint, then during operation, the portion of the item above its midpoint (50cm) will not be covered by the film structure. During the rotation of the item, the lifting mechanism 500 moves the item upwards along the axial direction of the roll film 300, aligning the portion of the item above its midpoint with the roll film 300. This allows the roll film 300 to wrap around the portion of the item above its midpoint, thus ensuring that the roll film 300 fully wraps the item. Furthermore, for items with strictly limited placement orientation, such as cylindrical items that are difficult to fix or have sharp parts, the roll film 300 needs to be wrapped around the outer periphery of the item at a specific angle. Therefore, the unwinding direction of the roll film 300 needs to be flexibly adjusted according to the specific item being packaged. The above methods are merely some examples for ease of understanding and do not limit the specific implementation.

[0041] In use, the item to be packaged is placed on the rotating mechanism 400. The end of the film structure of the roll film 300 is fixed to the outer circumference of the item to be packaged. The rotating mechanism 400 drives the item to be packaged to rotate, and the film structure of the roll film 300 is unwound from the roll and wrapped around the outer circumference of the item to be packaged. If the length of the item to be packaged is greater than the width of the roll film 300, the lifting mechanism 500 drives the item to be packaged to move vertically, so that the roll film 300 can fully wrap around the outer circumference of the item to be packaged. When changing to different items to be packaged, select the appropriate winding direction according to the item to be packaged, and rotate the fixing rod 200 to adjust the roll film 300 to the appropriate direction to facilitate packaging the item to be packaged.

[0042] With the above settings, items can be packaged automatically without manual operation, saving time and effort and effectively improving packaging efficiency. Furthermore, the unwinding direction of the film roll 300 can be adjusted according to the shape of the item to be packaged, improving adaptability to different shapes.

[0043] In some embodiments, the rotating mechanism 400 includes a support plate 410 and a first driving member 420, the first driving member 420 being connected to the support plate 410 and used to drive the support plate 410 to rotate.

[0044] See Figure 5 and Figure 6A first driving component 420 is located below the support plate 410. The first driving component 420 can be a motor or a cylinder. The output shaft of the first driving component 420 is connected to the center of the bottom surface of the support plate 410, driving the support plate 410 to rotate around its own center. The object to be packaged is placed on the support plate 410. When the support plate 410 rotates, it drives the object to be packaged to rotate, causing the object to pull the film structure to complete the packaging. Through the above arrangement, the object to be packaged can be driven to rotate, thereby achieving the purpose of packaging the object.

[0045] Furthermore, the surface of the support plate 410 that contacts the object to be packaged is a rough surface, which can provide greater friction and prevent the object from slipping during rotation, thus preventing the film structure from being pulled to complete the packaging. In addition, fasteners such as buckles and slots can be provided on the support plate 410 to ensure that the object to be packaged rotates synchronously with the support plate 410 to pull the film structure of the roll film 300, ensuring that the film structure of the roll film 300 can be wound around the outer periphery of the object to be packaged.

[0046] In some embodiments, the packaging device further includes two rotating connectors 210, both of which are coaxially arranged with the fixed rod 200 and respectively abut against both ends of the roll film 300.

[0047] See Figure 1 and Figure 5 Two rotating connectors 210 are respectively sleeved on both ends of the fixed rod 200. Each rotating connector 210 includes a rotating bearing, and the two rotating bearings abut against both ends of the roll film 300, thereby allowing the roll film 300 to rotate around the fixed rod 200. In this way, the film structure of the roll film 300 is unwound under the action of the object to be packaged.

[0048] In some embodiments, the lifting mechanism 500 includes a movable seat 510, a fixed seat 520, and a connecting assembly 530. The fixed seat 520 is connected to the frame 100, and the movable seat 510 is connected to the fixed seat 520 via the connecting assembly 530. The connecting assembly 530 is used to adjust the relative distance between the fixed seat 520 and the movable seat 510. The movable seat 510 is connected to the rotating mechanism 400.

[0049] See Figure 1 , Figure 2 , Figure 5 and Figure 6Both the movable seat 510 and the fixed seat 520 are plate-shaped structures. The movable seat 510 is stacked on the fixed seat 520. The movable seat 510 and the fixed seat 520 are connected by a connecting component 530. The connecting component 530 can drive the movable seat 510 to move vertically, allowing it to move closer to or away from the fixed seat 520, thereby adjusting the distance between the fixed seat 520 and the movable seat 510. During the movement of the movable seat 510, the rotating mechanism 400 and the item to be packaged can be driven to move in a predetermined direction (vertical direction). Through the above configuration, the rotating mechanism 400 and the item to be packaged can be driven to move in a predetermined direction, thus ensuring that the item to be packaged is fully packaged and protected. The lifting mechanism 500 does not require manual operation during normal operation, making it simple and convenient to use.

[0050] Furthermore, the connecting component 530 can be a telescopic component or a deformable component. The movable seat 510 and the fixed seat 520 are respectively connected to the two ends of the telescopic component or the deformable component. By controlling the deformation of the telescopic component or the deformable component, the length of the telescopic component or the deformable component is changed, thereby driving the movable seat 510, the rotating mechanism 400 and the object to be packaged to move.

[0051] In some embodiments, the connecting assembly 530 includes a first connecting rod 531 and a second connecting rod 532, the center of the first connecting rod 531 being rotatably connected to the center of the second connecting rod 532; the movable seat 510 has a first sliding groove 511, the fixed seat 520 has a second sliding groove 521, one end of the first connecting rod 531 is engaged with the first sliding groove 511 and moves along the length direction of the first sliding groove 511, the other end of the first connecting rod 531 is rotatably connected to the fixed seat 520, one end of the second connecting rod 532 is engaged with the second sliding groove 521 and moves along the length direction of the second sliding groove 521, the other end of the second connecting rod 532 is rotatably connected to the movable seat 510.

[0052] See Figure 1 , Figure 2 , Figure 5 and Figure 6 The first connecting rod 531 and the second connecting rod 532 are arranged crosswise, and the two connecting rods can rotate relative to each other around the central connection point. While the first connecting rod 531 moves along the first sliding groove 511, the second connecting rod 532 moves along the second sliding groove 521, thereby adjusting the included angle between the two connecting rods, and thus driving the movable seat 510 to move through the two connecting rods. For ease of understanding, as follows... Figure 7As shown in Figure b, in the initial state, both the first connecting rod 531 and the second connecting rod 532 are arranged horizontally, and the ends of both connecting rods are located at the left end of the slide groove. At this time, the distance between the fixed seat 520 and the movable seat 510 is the shortest, that is, the lifting mechanism 500 is at its lowest point. When it is necessary to drive the rotating mechanism 400 and the object to be packaged to move in a predetermined direction, the end of the first connecting rod 531 moves to the right along the first slide groove 511. Similarly, the end of the second connecting rod 532 moves to the right along the second slide groove 521, so that the angle between the first connecting rod 531 and the second connecting rod 532 in the horizontal direction gradually increases. Figure 7 As shown in Figure a, the distance between the movable seat 510 and the fixed seat 520 gradually increases, causing the movable seat 510 to drive the rotating mechanism 400 and the item to be packaged to move. Conversely, when the ends of the two connecting rods move to the left along the slide groove, the distance between the movable seat 510 and the fixed seat 520 decreases. This arrangement ensures that the rotating mechanism 400 moves in a predetermined direction, guaranteeing that even when the length of the item to be packaged is greater than the width of the roll film 300, the roll film 300 can still fully wrap the item. Furthermore, this arrangement makes the movement of the rotating mechanism 400 in the predetermined direction relatively smooth, resulting in more uniform packaging and improved packaging effectiveness.

[0053] In some embodiments, the lifting mechanism 500 further includes a second drive member 540, comprising at least one of the following:

[0054] The second driving member 540 is connected to the first connecting rod 531 and is used to drive the end of the first connecting rod 531 to move along the first slide groove 511.

[0055] The second driving member 540 is connected to the second connecting rod 532 and is used to drive the end of the second connecting rod 532 to move along the second slide groove 521.

[0056] See Figure 1 , Figure 2 and Figure 6A second driving member 540 is provided, and is connected to the first connecting rod 531. The second driving member 540 can drive the first connecting rod 531 to move along the first sliding groove 511 to adjust the angle formed by the first connecting rod 531 and the second connecting rod 532, thereby driving the movable seat 510 to move relative to the fixed seat 520. For ease of understanding, the first connecting rod 531 and the second connecting rod 532 are of the same length. Since the center of the first connecting rod 531 is rotatably connected to the center of the second connecting rod 532, when the first connecting rod 531 is driven to move, the second connecting rod 532 will move under the drive of the first connecting rod 531 and the movable seat 510 to ensure that the angle between the two connecting rods is the same. Only one connecting rod needs to be driven to make the movable seat 510 move relative to the fixed seat 520. Therefore, the second driving member 540 can also be connected to the second connecting rod 532, and the movable seat 510 can be moved relative to the fixed seat 520 by directly driving the second connecting rod 532.

[0057] Two second driving members 540 may be provided. One second driving member 540 is connected to the first connecting rod 531, and the other second driving member 540 is connected to the second connecting rod 532. The two second driving members 540 synchronously drive the first connecting rod 531 and the second connecting rod 532 to move, thereby driving the movable seat 510 to move relative to the fixed seat 520. With the above arrangement, the connecting assembly 530 can be driven in a reasonable manner to move the object to be packaged and the rotating mechanism 400.

[0058] Furthermore, the connecting assembly 530 is provided in two sets. The two first connecting rods 531 are connected by a crossbar 533, and the two second connecting rods 532 are also connected by a crossbar 533, so that the two sets of connecting assemblies 530 move synchronously. The second driving member 540 is connected to the crossbar 533, and drives the first connecting rods 531 and the second connecting rods 532 to move by pushing and pulling the crossbar 533. Through the above arrangement, both sets of connecting assemblies 530 can be driven to move simultaneously, avoiding damage to the two sets of connecting assemblies 530 due to uneven force.

[0059] In some embodiments, the second drive member 540 is a cylinder. See also Figure 2 and Figure 6 When the second driving component 540 is a cylinder, the cylinder's output shaft is connected to the first connecting rod 531 and extends and retracts along the length of the first sliding groove 511 to drive the first connecting rod 531. Similarly, the cylinder's output shaft can be connected to the second connecting rod 532 and moves along the length of the second sliding groove 521 to drive the second connecting rod 532. With the above configuration, the rotating mechanism 400 and the object to be packaged can be driven to move in a predetermined direction. No manual operation is required during the movement of the object to be packaged in this predetermined direction, saving time and effort and effectively improving packaging efficiency.

[0060] In some embodiments, the frame 100 is provided with a rotating seat 110 and a mounting seat 120, one end of the fixing rod 200 is rotatably connected to the rotating seat 110, and the other end of the fixing rod 200 is detachably connected to the mounting seat 120.

[0061] See Figure 1 , Figure 3 and Figure 4 One end of the fixing rod 200 is rotatably connected to the rotating seat 110, allowing the fixing rod 200 to rotate around the rotating seat 110. When the other end of the fixing rod 200 is connected to the mounting seat 120, the fixing rod 200 is fixed, thus fixing the unwinding direction of the roll film 300. When it is necessary to adjust the unwinding direction of the roll film 300, the other end of the fixing rod 200 is disconnected from the mounting seat 120, allowing the fixing rod 200 to rotate around the rotating seat 110 to a suitable direction before fixing the fixing rod 200 again. This allows the unwinding direction of the roll film 300 to be adjusted to correspond to the item to be packaged. Through the above settings, it is ensured that the roll film 300 does not shift during the packaging process, and the operation of rotating and adjusting the fixing rod 200 is simple and convenient, effectively improving the efficiency of changing the unwinding direction of the roll film 300.

[0062] In some embodiments, the packaging device further includes a fixing bolt (not shown in the figure); the mounting base 120 has a first mounting hole 121, and the end of the fixing rod 200 connected to the mounting base 120 has a first positioning hole 201. The first positioning hole 201 is correspondingly provided with the first mounting hole 121, and the fixing bolt is inserted into the first positioning hole 201 and the first mounting hole 121.

[0063] See Figure 1 and Figure 4 The first mounting hole 121 is located on the movement path of the first positioning hole 201 when the fixed rod 200 rotates, so that the first positioning hole 201 can be aligned with the first mounting hole 121. When the fixed rod 200 rotates to the point where the first positioning hole 201 is aligned with the first mounting hole 121, the fixing bolt is simultaneously inserted into the first positioning hole 201 and the first mounting hole 121, fixing the fixed rod 200 to the mounting base 120, so that the roll film 300 can wrap the items to be packaged. Through the above arrangement, the end of the fixed rod 200 is detachably connected to the mounting base 120, and the assembly and disassembly operations are simple and quick.

[0064] In some embodiments, the packaging device further includes a pin 220; the rotating seat 110 has a second mounting hole (not shown in the figure), and the end of the fixed rod 200 connected to the rotating seat 110 has a second positioning hole (not shown in the figure). The second positioning hole and the second mounting hole are correspondingly arranged, and the pin 220 is inserted into the second positioning hole and the second mounting hole.

[0065] See Figure 1 and Figure 3The pin 220 is simultaneously inserted into the second positioning hole and the second mounting hole, allowing the fixing rod 200 to rotate around the pin 220. This arrangement ensures that the fixing rod 200 rotates around the rotating seat 110.

[0066] For further details, please refer to [link / reference]. Figure 1 and Figure 3 The rotating base 110 also has a third mounting hole (not shown in the figure), which is located above the second mounting hole. The fixing rod 200 also has a third positioning hole 203. The second mounting hole is located on the movement path of the third positioning hole 203 when the fixing rod 200 rotates, so that the second mounting hole and the third positioning hole 203 are aligned. The pin 230 is detachably inserted into the second mounting hole and the third positioning hole 203 to fix the relative position of the fixing rod 200 and the frame 100. For ease of understanding, as shown below... Figure 2 As shown, when the pin 230 is pulled out, the fixing rod 200 can rotate around the pin 220 to adjust the relative position of the fixing rod 200 and the frame 100. When the second mounting hole and the third positioning hole 203 are aligned, the pin 230 is inserted into the second mounting hole and the third positioning hole 203. At this time, the fixing rod 200 cannot rotate, thus fixing the relative position of the fixing rod 200 and the frame 100. With the above settings, there is no need to connect and fix the other end of the fixing rod 200 to the mounting base 120. Both the second mounting hole and the third mounting hole are opened in the rotating base 110, which facilitates operation and maintenance.
