Description

Technical Field

[0001] This application relates to the field of stationery technology, and more specifically to a brush holder. Background Technology

[0002] The calligraphy brush is a traditional writing tool originating in China, an indispensable tool in calligraphy learning, and has gradually become a traditional painting tool. After use, the brush tip retains ink, and careless placement can cause the brush tip to smudge with other items. Therefore, a brush holder is needed to hang the brush during use. A brush holder is an accessory for calligraphy brushes, not only organizing the brushes neatly and preventing them from falling and soiling the brush tip and other items, but also preventing the brush tip from deforming. Existing brush holders can be divided into fixed and detachable types. Fixed brush holders are relatively bulky, making them difficult to transport and prone to damage. Detachable brush holders consist of a main body and a base, which are often fixed together with screws. This can easily lead to misalignment during assembly, requiring multiple adjustments after installation. Improper installation can result in an uneven base, affecting the actual use of the brush holder. To address the aforementioned issues, a utility model patent with authorization announcement number CN210502041U discloses a brush holder that is easy to disassemble and carry. The first and fifth hanging brackets are symmetrically mounted on the left and right bases. The right end face of the upper and lower horizontal bars of the first hanging bracket has a tenon, the left end face of the vertical bar of the second hanging bracket has a mortise for fixing the tenon, the left end face of the upper and lower horizontal bars of the fifth hanging bracket has a tenon, and the right end face of the vertical bar of the fourth hanging bracket has a mortise for fixing the tenon. The right end face of the upper and lower crossbars of the second bracket has a tenon, and the left end face of the first vertical bar of the third bracket has a mortise for fixing the tenon. The left end face of the upper and lower crossbars of the fourth bracket has a tenon, and the right end face of the second vertical bar of the third bracket has a mortise for fixing the tenon. In this technical solution, the base and the bracket are connected by an inverted T-shaped groove and an inverted T-shaped tenon. The brackets are connected to each other, the support is connected to the bracket, and the water tank is connected to the bracket by T-shaped tenons and T-shaped mortises. This brush holder has many parts, and the assembly is complicated and laborious. On the other hand, the brush holder is fixed and formed by the mortise and tenon connection structure. Although the mortise and tenon connection structure has the advantage of good stability, it has high precision requirements, which not only increases the production cost but also makes the assembly more laborious. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a brush holder in which the various parts of the brush holder are connected by snap-fit, the structure is stable and reliable, and the installation is simple and labor-saving.

The first locking part and the second locking part are snapped together to connect the first vertical bar and the first horizontal bar. The other end of the first vertical bar is provided with a third locking part. The first base is provided with a fourth locking part adapted to the first vertical bar. The third locking part and the fourth locking part are snapped together to connect the first vertical bar and the first base.

[0005] In this technical solution, a pen holder is provided on the first horizontal bar for hanging calligraphy brushes. Several pen holders are provided to accommodate different numbers of brushes according to user needs, thus meeting various usage requirements. A first snap-fit ​​part and a third snap-fit ​​part are respectively provided at both ends of the first vertical bar. The first vertical bar is connected to the second snap-fit ​​part of the first horizontal bar through the first snap-fit ​​part, and the first vertical bar is connected to the fourth snap-fit ​​part of the first base through the third snap-fit ​​part. Through the snap-fit ​​connection method, users can easily assemble and disassemble the calligraphy brush holder without the use of tools, saving effort and convenience. The snap-fit ​​connection method also provides stable structural support to ensure a firm connection between the first horizontal bar and the first vertical bar, and between the first vertical bar and the first base. Furthermore, the snap-fit ​​connection method can withstand repeated disassembly and assembly without losing its fastening force, making it more durable than screw connections. On the other hand, the connections of each snap-fit ​​part are hidden inside the components, which is more concealed and aesthetically pleasing than mortise and tenon joints, and has lower production requirements. The snap-fit ​​connection method can realize the integrated design of the calligraphy brush holder, improving the overall aesthetics and practicality.

The assembly and disassembly principles are the same. The first and second snap-fit ​​parts adopt a snap-fit ​​and snap-slot mating structure, which enables precise positioning during insertion. Furthermore, after the first and second snap-fit ​​parts are inserted, a snap-fit ​​lock is achieved by rotation. The snap-fit ​​structure is inserted into the snap-slot structure and then locked by rotation, providing a firm connection and enhancing the stability of the overall structure. Quick locking is achieved through rotation, improving overall assembly efficiency and making assembly and disassembly easier and faster.

[0009] As an improvement, the second latching part is provided with a first positioning protrusion on both sides, and the first latching part is provided with a first positioning hole on both sides.

The fourth latching part is provided with a second positioning protrusion on both sides, and the third latching part is provided with a second positioning hole on both sides. After the third latching part and the fourth latching part are inserted, the second positioning protrusion is connected to the second positioning hole by rotation. In this technical solution, the first and second locking parts are connected and rotated after insertion to achieve a precise fit between the first positioning protrusion and the first positioning hole. This operation is simple and labor-saving. Furthermore, the connection between the first positioning protrusion and the first positioning hole further improves the connection stability between the first upright and the first crossbar, reducing loosening of the connection due to external forces. Similarly, the third and fourth locking parts are connected and rotated after insertion to achieve a precise fit between the second positioning protrusion and the second positioning hole. This operation is simple and labor-saving. Furthermore, the connection between the second positioning protrusion and the second positioning hole further improves the connection stability between the first upright and the first base, reducing loosening of the connection due to external forces.

[0010] As an improvement, the groove structure is provided with opposing first and second limiting protrusions. An opening is formed between the first and second limiting protrusions for the insertion of a locking pin structure. The locking pin structure passes through the opening and is inserted into the groove structure. The locking pin structure rotates to abut against the first and second limiting protrusions for limitation. In this technical solution, the first and second limiting protrusions are provided within the groove structure. The locking pin structure is inserted into the groove structure through the opening formed between the first and second limiting protrusions. After rotating within the groove structure, the locking pin structure abuts against the first and second limiting protrusions. The first and second limiting protrusions limit the locking pin structure within the groove structure, ensuring the connection stability between the locking pin structure and the groove structure, reducing the risk of loosening or falling off due to external forces, and the first and second limiting protrusion structures are simple and reliable.

[0011] As an improvement, the outer walls of both the first and second limiting protrusions are provided with a first guide slope adapted to the locking pin structure. The locking pin structure is inserted into the snap-fit ​​structure along the first guide slope. In this technical solution, both the first and second limiting protrusions simplify the insertion process of the locking pin structure by providing a first guide slope, allowing the locking pin structure to slide more smoothly into the snap-fit ​​structure along the first guide slope, thereby improving assembly efficiency and convenience, and making disassembly and assembly more labor-saving and efficient. In this solution, the first guide slope is preferably an arc surface structure. The arc surface structure not only has a better guiding effect, but also makes it less prone to wear when the locking pin structure collides with the arc surface structure during the insertion process with the snap-fit ​​structure, thus improving the overall service life.

[0012] As an improvement, the insertion end of the locking pin structure is provided with a first guide arc surface, and the locking pin structure is inserted into the buckle groove structure and rotated through the first guide arc surface; the inner sidewall of the first limiting protrusion is provided with a first abutting plane adapted to the locking pin structure, and the inner sidewall of the second limiting protrusion is provided with a second guide slope adapted to the locking pin structure. In this technical solution, the insertion end of the locking pin structure is designed with a first guide arc surface, which allows the locking pin structure to be smoothly inserted into the slot structure through the first guide arc surface. This reduces friction and resistance during the insertion process, thereby reducing assembly difficulty and wear on the locking pin structure and the slot structure. Furthermore, the locking pin structure can rotate within the slot structure through the first guide arc surface, making assembly easier and improving overall assembly and disassembly efficiency. On the other hand, a first abutting plane is provided within the first limiting protrusion. After the locking pin structure is inserted into the slot structure, it rotates and abuts against the first abutting plane. The first abutting plane can prevent the locking pin structure from detaching from the slot structure, enhancing connection stability and reliability. A second guide slope is provided within the second limiting protrusion, which can improve the rotation efficiency of the locking pin structure within the slot structure, thereby improving assembly and disassembly efficiency. In this solution, the second guide slope is preferably an arc surface structure. The arc surface structure not only has a better guiding effect, but also makes the locking pin structure less prone to wear when colliding with the arc surface structure, thus improving the overall service life.

One end of the second upright is connected to the first crossbar, and the other end of the second upright is connected to the second base. One end of the second upright is provided with a fifth locking part, and the first crossbar is provided with a sixth locking part adapted to the fifth locking part. The fifth locking part and the sixth locking part are snapped together to connect the second upright and the first crossbar. The other end of the second upright is provided with a seventh locking part, and the second base is provided with an eighth locking part adapted to the second upright. The seventh locking part and the eighth locking part are snapped together to connect the second upright and the second base. In this technical solution, a second upright and a second base are added, with two uprights and two bases. Each upright is connected to a base. The second upright cooperates with the first upright to support the first horizontal bar, improving the stability of the first horizontal bar when hanging the brushes. A fifth and a seventh locking part are respectively provided at both ends of the second upright. The second upright is connected to the sixth locking part of the first horizontal bar via the fifth locking part, and to the eighth locking part of the second base via the seventh locking part.

The snap-fit ​​connection method also provides stable structural support to ensure a firm connection between the first horizontal bar and the second vertical bar, and between the second vertical bar and the second base. The snap-fit ​​connection method can withstand repeated disassembly and assembly without losing its fastening force, and is more durable than the screw connection method. On the other hand, the connections of each snap-fit ​​part are hidden inside the parts, which is more concealed and aesthetically pleasing than the mortise and tenon connection structure, and has lower production requirements. The snap-fit ​​connection method can realize the integrated design of the brush holder, improving the overall aesthetics and practicality.

[0014] As an improvement, the fifth and sixth locking parts are inserted into each other and locked by rotation; the seventh and eighth locking parts are inserted into each other and locked by rotation. In this technical solution, the aforementioned structural design allows users to complete assembly or disassembly with simple insertion and rotation actions, requiring no additional tools.

The rotation locking structure better ensures that each locking part is not easily loosened under external force, improving the stability of the structure. Compared to the direct insertion and removal method, the rotation locking of each locking part in this solution helps reduce wear and tear, thereby extending the service life of each locking part.

Furthermore, the locking connection method can withstand repeated disassembly and assembly without losing its fastening force, making it more durable than screw connections. On the other hand, the connections of each locking part are hidden inside the components, offering better concealment and aesthetics compared to mortise and tenon joints, and lower production requirements. The locking connection method also enables an integrated design for the brush holder, improving both its overall aesthetics and practicality.

[0016] As an improvement, the ninth and tenth locking parts are inserted into each other and locked by rotation; the eleventh and twelfth locking parts are also inserted into each other and locked by rotation. In this technical solution, the aforementioned structural design allows users to complete assembly or disassembly with simple insertion and rotation actions, requiring no additional tools. The operation is simple and labor-saving, and the connection and locking of each component can be achieved by rotation, resulting in higher assembly efficiency. The rotation locking structure better ensures that each locking part is not easily loosened under external force, improving the stability of the structure. Compared to the direct insertion and removal method, the rotation locking of each locking part in this solution helps reduce wear and tear, thereby extending the service life of each locking part.

[0029] Example 1

[0030] like Figures 1 to 7As shown, this application discloses a brush holder, including a first horizontal bar 1, a first vertical bar 2, and a first base 3. The first horizontal bar 1 is provided with a plurality of brush hangers 11 for hanging brushes. The number of brush hangers 11 allows for hanging different numbers of brushes according to user needs, satisfying various usage requirements. One end of the first vertical bar 2 is provided with a first engaging portion 21, and the first horizontal bar 1 is provided with a second engaging portion 12 adapted to the first engaging portion 21. The first engaging portion 21 and the second engaging portion 12 are engaged to connect the first vertical bar 2 and the first horizontal bar 1. The other end of the first vertical bar 2 is provided with a third engaging portion 22, and the first base 3 is provided with a fourth engaging portion 31 adapted to the first vertical bar 2. The third engaging portion 22 and the fourth engaging portion 31 are engaged to connect the first vertical bar 2 and the first base 3. The first engaging portion 21 is provided at both ends of the first vertical bar 2. The first upright 2 is connected to the second snap-fit ​​part 12 of the first horizontal bar 1 via the first snap-fit ​​part 21, and the first upright 2 is connected to the fourth snap-fit ​​part 31 of the first base 3 via the third snap-fit ​​part 22. Through the snap-fit ​​connection method, users can easily assemble and disassemble the brush holder without the need for tools, saving effort and convenience. The snap-fit ​​connection method can also provide stable structural support to ensure that the connection between the first horizontal bar 1 and the first upright 2, and between the first upright 2 and the first base 3 is firm. Moreover, the snap-fit ​​connection method can withstand repeated disassembly and assembly without losing its fastening force, and is more durable than the screw connection method. On the other hand, the connection of each snap-fit ​​part is hidden inside the parts, which is more concealed and aesthetically pleasing than the mortise and tenon connection structure, and has lower production requirements. The snap-fit ​​connection method can realize the integrated design of the brush holder, improving the overall aesthetics and practicality.

[0031] More specifically, such as Figures 1 to 3 As shown, the first snap-fit ​​part 21 is inserted into the second snap-fit ​​part 12 and locked by rotation; the third snap-fit ​​part 22 is inserted into the fourth snap-fit ​​part 31 and locked by rotation. The aforementioned structural design allows users to complete assembly or disassembly with simple insertion and rotation actions, without the need for additional tools. The operation is simple and labor-saving, and the connection and locking of each component can be achieved by rotation, resulting in higher assembly efficiency. The rotation locking structure better ensures that each snap-fit ​​part is not easy to loosen when subjected to external force, thus improving the stability of the structure. Compared with the direct insertion and removal method, the rotation locking of each snap-fit ​​part in this solution helps to reduce its own wear, thereby extending the service life of each snap-fit ​​part.

[0032] More specifically, the first latching part 21 and the second latching part 12 have at least two specific structural designs, one of which is: Figure 3As shown, the first snap-fit ​​part 21 is a snap-fit ​​structure and the second snap-fit ​​part 12 is a snap-slot structure. Alternatively, the first snap-fit ​​part 21 is a snap-slot structure and the second snap-fit ​​part 12 is a snap-fit ​​structure. The two have the same disassembly and assembly principle. The first snap-fit ​​part 21 and the second snap-fit ​​part 12 adopt a snap-fit ​​and snap-slot matching structure, which can achieve precise positioning during insertion. Furthermore, after the first snap-fit ​​part 21 and the second snap-fit ​​part 12 are inserted, they are locked by rotation. The snap-fit ​​structure is inserted into the snap-slot structure and then locked by rotation, providing a firm connection and enhancing the stability of the overall structure. The rotation action achieves quick locking, improving the overall assembly efficiency and making disassembly and assembly more labor-saving and quick.

[0033] More specifically, the third latching part 22 and the fourth latching part 31 have at least two specific structural designs, one of which is: Figure 3 As shown, the third snap-fit ​​part 22 is a snap-fit ​​structure and the fourth snap-fit ​​part 31 is a snap-slot structure. Alternatively, the third snap-fit ​​part 22 is a snap-slot structure and the fourth snap-fit ​​part 31 is a snap-fit ​​structure. The disassembly and assembly principles of the two are the same. The third snap-fit ​​part 22 and the fourth snap-fit ​​part 31 adopt a snap-fit ​​and snap-slot matching structure, which can achieve precise positioning during insertion. Furthermore, after the third snap-fit ​​part 22 and the fourth snap-fit ​​part 31 are inserted, they are locked by rotation. The snap-fit ​​structure is inserted into the snap-slot structure and then locked by rotation, providing a firm connection and enhancing the stability of the overall structure. The rotation action achieves quick locking, improving the overall assembly efficiency and making disassembly and assembly more labor-saving and faster.

[0034] More specifically, such as Figure 2 and Figure 3 As shown, the snap-fit ​​structure is provided with opposing first limiting protrusions 41 and second limiting protrusions 42. An opening for the insertion of the locking pin structure is formed between the first limiting protrusions 41 and the second limiting protrusions 42. The locking pin structure passes through the opening and is inserted into the snap-fit ​​structure. The locking pin structure is rotated to abut against the first limiting protrusions 41 and the second limiting protrusions 42 for limitation. The first limiting protrusions 41 and the second limiting protrusions 42 are provided in the snap-fit ​​structure. The locking pin structure is inserted into the snap-fit ​​structure through the opening formed between the first limiting protrusions 41 and the second limiting protrusions 42. After rotating in the snap-fit ​​structure, the locking pin structure abuts against the first limiting protrusions 41 and the second limiting protrusions 42. The first limiting protrusions 41 and the second limiting protrusions 42 limit the locking pin structure in the snap-fit ​​structure, ensuring the connection stability between the locking pin structure and the snap-fit ​​structure, reducing the risk of loosening or falling off due to external forces, and the structure of the first limiting protrusions 41 and the second limiting protrusions 42 is simple and reliable.

[0035] More specifically, such as Figure 2 and Figure 3As shown, the outer walls of the first limiting protrusion 41 and the second limiting protrusion 42 are both provided with a first guide slope 43 adapted to the locking pin structure. The locking pin structure is inserted into the snap-fit ​​structure along the first guide slope 43. The first limiting protrusion 41 and the second limiting protrusion 42 simplify the insertion process of the locking pin structure by providing the first guide slope 43, so that the locking pin structure can slide more smoothly into the snap-fit ​​structure along the first guide slope 43, thereby improving assembly efficiency and convenience, and making disassembly and assembly more labor-saving and efficient. In this solution, the first guide slope 43 is preferably an arc surface structure. The arc surface structure not only has a better guiding effect, but also the locking pin structure is less likely to wear when it collides with the arc surface structure during the insertion process with the snap-fit ​​structure, thus improving the overall service life.

[0036] More specifically, such as Figure 5 and Figure 7 As shown, the insertion end of the locking pin structure is provided with a first guide arc surface 44. The locking pin structure is inserted into the snap-fit ​​structure and rotates through the first guide arc surface 44. The first guide arc surface 44 at the insertion end of the locking pin structure allows the locking pin structure to be smoothly inserted into the snap-fit ​​structure through the first guide arc surface 44, reducing friction and resistance during the insertion process, thereby reducing assembly difficulty and wear on the locking pin structure and snap-fit ​​structure. Furthermore, the locking pin structure can rotate within the snap-fit ​​structure through the first guide arc surface 44, making assembly easier and improving the overall assembly and disassembly efficiency.

[0037] More specifically, such as Figure 2 and Figure 5 As shown, the inner wall of the first limiting protrusion 41 is provided with a first abutting surface 411 adapted to the locking pin structure, and the inner wall of the second limiting protrusion 42 is provided with a second guide slope 421 adapted to the locking pin structure. The first abutting surface 411 is provided in the first limiting protrusion 41. After the locking pin structure is inserted into the snap-lock structure, the locking pin structure fits against the first abutting surface 411 by rotation. The first abutting surface 411 can restrict the locking pin structure from detaching from the snap-lock structure, thereby enhancing the connection stability and reliability. The second guide slope 421 is provided in the second limiting protrusion 42, which can improve the rotation efficiency of the locking pin structure in the snap-lock structure, thereby improving the disassembly and assembly efficiency. In this solution, the second guide slope 421 is preferably an arc surface structure. The arc surface structure not only has a better guiding effect, but also the locking pin structure is not easy to wear when it collides with the arc surface structure, thus improving the overall service life.

[0038] More specifically, such as Figure 1 and Figure 3As shown, it also includes a second upright 5 and a second base 6. One end of the second upright 5 is connected to the first horizontal bar 1, and the other end of the second upright 5 is connected to the second base 6. A fifth snap-fit ​​part 51 is provided at one end of the second upright 5, and a sixth snap-fit ​​part 13 adapted to the fifth snap-fit ​​part 51 is provided on the first horizontal bar 1. The fifth snap-fit ​​part 51 and the sixth snap-fit ​​part 13 are snapped together to connect the second upright 5 and the first horizontal bar 1. The addition of the second upright 5 and the second base 6 provides two uprights and two bases. Each upright is connected to a base. The second upright 5 and the first upright 2 cooperate to support the first horizontal bar 1, making the stability of hanging the brush on the first horizontal bar 1 better.

[0039] The second upright 5 has a seventh locking part 52 at one end, and an eighth locking part 61 adapted to the second upright 5 on the second base 6. The seventh locking part 52 and the eighth locking part 61 are fastened together to connect the second upright 5 to the second base 6. A fifth locking part 51 and a seventh locking part 52 are respectively provided at both ends of the second upright 5. The second upright 5 is fastened to the sixth locking part 13 of the first crossbar 1 via the fifth locking part 51, and to the eighth locking part 61 of the second base 6 via the seventh locking part 52.

Furthermore, all the snap-fit ​​connections are hidden inside the components, offering better concealment and aesthetics compared to mortise and tenon joints, while also reducing production requirements. The snap-fit ​​connection allows for an integrated design of the pen holder, improving both its overall aesthetics and practicality.

[0040] More specifically, such as Figure 2 and Figure 3 As shown, the fifth snap-fit ​​part 51 and the sixth snap-fit ​​part 13 are inserted into each other and locked by rotation; the seventh snap-fit ​​part 52 and the eighth snap-fit ​​part 61 are inserted into each other and locked by rotation. The aforementioned structural design allows users to complete assembly or disassembly with simple insertion and rotation actions, without the need for additional tools. The operation is simple and labor-saving, and the connection and locking of each component can be achieved by rotation, which improves the assembly efficiency. The rotation locking structure better ensures that each snap-fit ​​part is not easy to loosen when subjected to external force, thus improving the stability of the structure. Compared with the direct insertion and removal method, the rotation locking of each snap-fit ​​part in this solution helps to reduce its own wear, thereby extending the service life of each snap-fit ​​part.

[0041] More specifically, the fifth latching part 51 and the sixth latching part 13 have at least two specific structural designs, one of which is: as follows Figure 3As shown, the fifth snap-fit ​​part 51 is a snap-fit ​​structure and the sixth snap-fit ​​part 13 is a snap-slot structure. Alternatively, the fifth snap-fit ​​part 51 is a snap-slot structure and the sixth snap-fit ​​part 13 is a snap-fit ​​structure. The disassembly and assembly principles of the two are the same. The fifth snap-fit ​​part 51 and the sixth snap-fit ​​part 13 adopt a snap-fit ​​and snap-slot matching structure, which can achieve precise positioning during insertion. Furthermore, after the fifth snap-fit ​​part 51 and the sixth snap-fit ​​part 13 are inserted, they are locked by rotation. The snap-fit ​​structure is inserted into the snap-slot structure and then locked by rotation, providing a firm connection and enhancing the stability of the overall structure. The rotation action achieves quick locking, improving the overall assembly efficiency and making disassembly and assembly more labor-saving and faster.

[0042] More specifically, the seventh latching part 52 and the eighth latching part 61 have at least two specific structural designs, one of which is: as follows Figure 3 As shown, the seventh snap-fit ​​part 52 is a snap-fit ​​structure and the eighth snap-fit ​​part 61 is a snap-slot structure.

Through the snap-fit ​​connection method, users can easily assemble and disassemble without the need for tools, saving effort and convenience. The snap-fit ​​connection method can also provide stable structural support to ensure that the first upright post 2 and the second upright post 5 are firmly connected to the second crossbar 7. Moreover, the snap-fit ​​connection method can withstand repeated disassembly and assembly without losing its fastening force, and is more durable than the screw connection method. On the other hand, the connection of each snap-fit ​​part is hidden inside the parts, which is more concealed and aesthetically pleasing than the mortise and tenon connection structure, and has lower production requirements. The snap-fit ​​connection method can realize the integrated design of the brush holder, improving the overall aesthetics and practicality.

Both sides of the second latching part 12 are provided with first positioning protrusions 121, and both sides of the first latching part 21 are provided with first positioning holes 211. After the first latching part 21 and the second latching part 12 are inserted, rotation connects the first positioning protrusions 121 and the first positioning holes 211. By inserting and rotating the first latching part 21 and the second latching part 12, precise matching of the first positioning protrusions 121 and the first positioning holes 211 can be achieved. This operation is simple and effortless. Furthermore, the connection between the first positioning protrusions 121 and the first positioning holes 211 further improves the connection stability between the first upright 2 and the first horizontal bar 1, reducing loosening of the connection due to external forces. Alternatively, the first positioning protrusions 121 can also be located on both sides of the first latching part 21, and the first positioning holes 211 can be correspondingly located on both sides of the second latching part 12. The principle is the same and will not be elaborated further.

[0049] More specifically, such as Figure 6 and Figure 7As shown, the fourth locking part 31 has second positioning protrusions 311 on both sides, and the third locking part 22 has second positioning holes 221 on both sides. After the third locking part 22 and the fourth locking part 31 are inserted, the second positioning protrusions 311 are connected to the second positioning holes 221 by rotation. By setting the third locking part 22 and the fourth locking part 31 to be inserted and then rotated, the second positioning protrusions 311 and the second positioning holes 221 can be precisely matched. The operation is simple and labor-saving. Furthermore, the connection and cooperation of the second positioning protrusions 311 and the second positioning holes 221 further improves the connection stability between the first upright 2 and the first base 3 and reduces the loosening of the connection due to external forces. On the other hand, the second positioning protrusions 311 can also be set on both sides of the third locking part 22, and the second positioning holes 221 can be correspondingly set on both sides of the fourth locking part 31. The principle is the same and will not be described in detail.
