Description

Technical Field

[0001] The invention belongs to the technical field, and in particular relates to a telescopic stool. Background Art

[0002] Stools are leisure furniture that people often use in their daily lives and are widely used in many occasions, such as bedrooms, offices, laboratories, and outdoor places. Currently, the known stools have fixed dimensions and are large in size. They are not convenient to carry for outdoor sports and lack flexibility, so telescopic stools have emerged. The telescopic mechanism in a telescopic stool is crucial for a telescopic stool. After the telescopic stool is stretched, it needs a reliable support force to support it. Although the existing telescopic mechanism can achieve the telescopic function, its support effect needs to be improved, which reduces the load-bearing capacity of the telescopic stool. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention provides a telescopic stool with a firm structure.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a telescopic stool, comprising a stool surface, a stool bottom, a telescopic mechanism and a first transition mechanism for connecting the stool surface and the telescopic structure, the first transition mechanism comprising an upper transition portion arranged on the stool surface and a first transition piece matched with the upper transition portion; the telescopic mechanism can switch between an expanded state and a contracted state, the telescopic mechanism comprises a plurality of relatively movable connecting parts and a fixing mechanism arranged on the connecting parts, the fixing mechanism is used to keep the telescopic mechanism in an expanded state; when the plurality of connecting parts are expanded, the expanded connecting parts are fixed by the fixing mechanism so that the connecting parts are in an expanded state, providing a good support effect for the expanded connecting parts, and ensuring the reliability of the use of the telescopic mechanism.

[0005] Furthermore, the fixing mechanism includes a first limiting structure for providing axial limiting for the connecting member; when the multiple connecting members are unfolded, the first limiting structure is used to provide axial limiting effect on the connecting member, provide supporting force for the unfolded connecting member, effectively fix the connecting member in a specified position, and enable the multiple connecting members to cooperate with each other to provide stable supporting force, thereby ensuring the reliability of the use of the telescopic mechanism.

[0006] Furthermore, the first limiting structure includes a first limiting portion provided on the connecting member and a second limiting portion cooperating with the first limiting portion on the adjacent connecting member; after the telescopic mechanism is unfolded, the limiting portion is used to provide supporting force for the connecting member, so that the telescopic mechanism is kept in the unfolded state, thereby increasing the reliability of the use of the telescopic mechanism; the adjacent connecting member is used to provide supporting force for the previous connecting member, so that the entire telescopic mechanism is more compact, the structural strength of the telescopic mechanism is increased, and the telescopic mechanism is more stable when in use.

[0007] Furthermore, the fixing mechanism also includes a second limiting structure for providing circumferential limiting for the connecting member; when the multiple connecting members are unfolded, the second limiting structure is used to provide circumferential limiting for the connecting member, so that the connecting member cannot rotate, thereby effectively fixing the connecting member in a specified position, so that the multiple connecting members cooperate with each other to provide stable supporting force, thereby ensuring the reliability of the use of the telescopic mechanism.

[0008] Furthermore, the second limiting structure includes a first inclined surface arranged on the first limiting part and a second inclined surface arranged on the second limiting part, and the first inclined surface matches with the second inclined surface on the adjacent connecting member; after the connecting structure is unfolded, the second inclined surface is placed on the first inclined surface, and with the mutual cooperation of the first inclined surface and the second inclined surface, the center of gravity of the first limiting part is placed at the bottom end of the first inclined surface, so as to prevent the first limiting part from escaping from the second limiting part and improve the connection effect.

[0009] Furthermore, the second limiting structure also includes a first anti-rotation portion provided on the second limiting portion and a second anti-rotation portion cooperating with the first anti-rotation portion on the adjacent connecting member, thereby further improving the circumferential limiting effect.

[0010] Furthermore, the fixing mechanism also includes a third limiting structure for providing radial limiting for the connecting member, thereby preventing the connecting member from generating radial deformation, thereby making the structure more stable and lightweight.

[0011] Furthermore, the third limiting structure includes a fifth limiting portion provided on the connecting member and a sixth limiting portion cooperating with the fifth limiting portion on the adjacent connecting member to achieve radial limiting.

[0012] Furthermore, the telescopic mechanism also includes a limiting structure for preventing two adjacent connecting members from separating from each other.

[0013] Furthermore, the connecting member is provided with a supporting mechanism for dispersing the force on the connecting member; by arranging the supporting mechanism on the connecting member, the supporting capacity of the connecting member is increased, so that the supporting member can be made thinner and lighter, so that the connecting member has greater supporting force at a thinner thickness, thereby ensuring the use quality of the telescopic stool; the supporting mechanism is utilized to make the connecting member have the same supporting force at a smaller thickness, and the weight of the telescopic stool is reduced by the thinness of the connecting member, thereby reducing the overall weight of the telescopic stool, so that the telescopic stool can be driven to move after being folded, thereby making the portability of the telescopic stool more prominent and enhancing the market competitiveness of the telescopic stool.

[0014] Furthermore, the supporting mechanism includes a load-bearing component for providing axial supporting force and a reinforcing component for providing radial supporting force; the load-bearing component and the reinforcing component cooperate with each other to provide supporting force for the connecting member from multiple directions, so that the telescopic stool has a larger supporting force when unfolded, thereby ensuring the structural strength of the telescopic stool; through the arrangement of the reinforcing component and the load-bearing component, the connecting member can have the same supporting strength with a smaller thickness, and the thickness of the connecting member can be adjusted to reduce the weight of the entire telescopic stool.

[0015] Furthermore, the bearing assembly includes a plurality of first bearing members arranged on the inner wall of the connecting member and a second bearing member for dispersing the force on the first bearing members; the first bearing members play a role of overall support, and the second bearing members cooperate with the first bearing members to play an auxiliary supporting role, thereby reducing the load of the first bearing members and protecting the first bearing members. The two bearing members cooperate with each other to provide good supporting force for the connecting member, thereby effectively improving the structural strength of the connecting member.

[0016] Furthermore, the reinforcing component includes a third bearing member arranged obliquely and a fourth bearing member cooperating with the third bearing member, which provides a reinforcing effect, improves the deformation resistance of the connecting member, and prevents the connecting member from deforming when squeezed and affecting the supporting effect on the stool surface.

[0017] Furthermore, the third bearing member and the fourth bearing member are cross-arranged, so that the two bearing members form a triangular structure, and the stability of the triangle is used to further enhance the supporting effect of the strengthening component on the connecting member, thereby effectively enhancing the structural strength of the connecting member.

[0018] Furthermore, the fourth bearing member is provided with bearing feet; the force direction of the fourth bearing member is changed by setting the bearing feet, the force on the fourth bearing member is dispersed, and the supporting effect of the fourth bearing member on the connecting member is further improved.

[0019] Furthermore, it also includes an anti-slip mechanism for keeping the telescopic stool in a retracted state; when the telescopic stool is not in use, the stool surface is pressed downward to retract the telescopic stool, and the stool surface is lowered onto the base, and the stool surface is fixed to the base using the anti-slip mechanism, so that the base and the stool surface form a whole, ensuring the connection effect between the base and the stool surface, preventing the stool surface from falling off the base after the telescopic stool is folded, ensuring the structural stability of the telescopic stool, and thus extending the service life of the telescopic stool.

[0020] Furthermore, the anti-slip mechanism includes a fixing component for locking the stool surface and the stool bottom with each other; under the action of the fixing component, the stool surface of the telescopic stool is stably fixed on the base after being retracted, preventing the stool surface from detaching from the base, ensuring the structural stability of the telescopic stool, and extending the service life of the telescopic stool.

[0021] Furthermore, the fixing assembly includes a first anti-detachment portion provided on the stool surface and a second anti-detachment portion cooperating with the first anti-detachment portion; when the telescopic stool is folded, the stool surface is on the base, and the first anti-detachment portion cooperates with the second anti-detachment portion to fix the stool surface, so that the stool surface cannot be separated from the base, thereby playing a good fixing effect on the stool surface to ensure the stability of the telescopic stool during transportation.

[0022] Furthermore, the anti-slip mechanism also includes an anti-slip component for preventing the stool top and the stool bottom from moving away from each other; the anti-slip component cooperates with the fixing component to further enhance the fixing effect of the stool top and the base, thereby preventing the stool top from separating from the base during the transportation of the telescopic stool.

[0023] Furthermore, the anti-slip assembly includes a third anti-slip portion connected to the stool surface and a fourth anti-slip portion matched with the third anti-slip portion.

[0024] Furthermore, the anti-slip assembly includes an upper connecting portion arranged on the stool surface, a lower connecting portion arranged on the stool bottom, and a reset member for connecting the upper connecting portion and the lower connecting portion.

[0025] Furthermore, the anti-slip mechanism also includes a limiting structure for preventing the movement of the connecting member.

[0026] Furthermore, the limiting structure includes a sixth anti-slip portion provided on the stool bottom and a first transition piece matched with the sixth anti-slip portion.

[0027] Furthermore, it also includes a luminous body for generating light and a light-transmitting area for allowing the light to pass through; when the telescopic stool is in use, the luminous body makes the telescopic stool emit light, so that the telescopic stool can attract more consumers' attention and enhance the attractiveness of the telescopic stool; the luminous body can emit light of various colors, and can also emit light of different intensities as needed, so that the light has different effects in different situations, and can be used to set the atmosphere or serve as a warning sign, thereby maximizing the function of the telescopic stool, greatly enhancing the functionality of the telescopic stool, and increasing the sales prospects of the telescopic stool; under the setting of the light-transmitting area, the light emitted by the luminous body is transmitted, which has a buffering effect on the light generated by the luminous body, avoiding the light of the luminous body from directly shining into the eyes of the user, increasing the softness of the light, and at the same time increasing the hazy beauty of the telescopic stool when it is illuminated through the light-transmitting area, enhancing the aesthetics of the telescopic stool, and further enhancing the sales prospects of the telescopic stool.

[0028] Furthermore, the light-transmitting area is a hollow structure that runs through one or more of the stool surface, stool bottom, and connecting parts; the light-transmitting area is set on any component of the stool surface, the base, and the connecting parts, so that a designated area on the telescopic stool is illuminated, and the telescopic stool has a variety of different functions through the light emission of different areas of the telescopic stool, thereby meeting the different needs of the telescopic stool in various occasions and increasing the functionality of the telescopic stool.

[0029] Furthermore, the light-transmitting area is a groove structure provided on one or more of the stool surface, stool bottom, and connecting parts; through the groove setting, the distance from the light-emitting body to the outside world is reduced, so that the light of the light-emitting body can be more easily transmitted, avoiding the light from directly piercing the eyes of the user, and increasing the softness of the light, so that the telescopic stool can be used to create an atmosphere.

[0030] Furthermore, the hollow structure is an opening provided on the stool surface; the light emitted by the light-emitting body is transmitted through the opening on the stool surface, and the light-emitting body can emit light of a plurality of different colors. At the same time, the light-emitting body is controlled to flash at intervals so that the light generated by the light-emitting body is transmitted from the stool surface. The telescopic stool can be placed in a construction site to serve as a warning sign.

[0031] Furthermore, the hollow structure is an opening provided on the connecting piece; the opening on the connecting piece can be set to a company logo or other exquisite patterns, and the light generated by the light-emitting body when working is emitted from the opening on the connecting piece. The opening pattern on the connecting piece can be mapped on the wall, which plays a promotional or beautification role, caters to the tastes of more consumers, and increases the market prospects of telescopic stools.

[0032] Furthermore, the light-emitting body is arranged on one or more of the stool surface, stool bottom, and connecting piece; the light-emitting body is arranged at different positions so that the light-emitting body corresponds to different light-transmitting areas on the telescopic stool, and the distance from the light-emitting body to the light-transmitting area is reduced so that the light of the light-emitting body can be normally emitted from the light-transmitting area, thereby increasing the conspicuousness of the light and making the telescopic stool have an obvious warning effect when serving as a warning sign.

[0033] Furthermore, it also includes a reflective area for reflecting the light; through the setting of the light-emitting area, the telescopic stool can be directly observed in the area with weak light, so as to determine the position of the telescopic stool; the light emitted by the light-emitting body is reflected through the reflective area, further improving the light intensity of the light-emitting body, and a brighter light can be obtained by using a light-emitting body with lower power, thereby extending the battery life and making the telescopic stool more convenient to use.

[0034] Furthermore, it also includes a mounting portion arranged on the stool surface, a cover plate matched with the mounting portion, and a locking structure for connecting the mounting portion and the cover plate.

[0035] Furthermore, the locking structure includes a mounting groove provided on the cover plate and a clamping member matched with the mounting groove.

[0036] Furthermore, it also includes an extended structure that can provide auxiliary functions.

[0037] Furthermore, the expansion structure includes one or more of an audio system, a wireless charging component, a buzzer, and a photovoltaic charging component; by installing expansion structures with multiple different functions on the telescopic stool, the telescopic stool has more functions in daily use, meeting the different needs of consumers for the telescopic stool and improving the practicality of the telescopic stool.

[0038] In summary, the present invention fixes the unfolded connecting member by setting a fixing mechanism, so that the connecting member is in an unfolded state, provides a good supporting effect for the unfolded connecting member, and ensures the reliability of the telescopic mechanism.

[0079] Embodiment 1:

[0080] like Figure 1-11As shown, a telescopic stool comprises a stool surface 1, a stool bottom 2, a telescopic mechanism, a first transition mechanism and a second transition mechanism; the telescopic mechanism comprises a plurality of relatively movable connecting members 3, the plurality of connecting members 3 are connected end to end, the connecting members are arranged in a circular ring structure, the diameters of the plurality of connecting members increase successively from top to bottom, so that the telescopic mechanism can switch between an expanded state and a contracted state, when every two adjacent connecting members are away from each other to the farthest end, the telescopic mechanism is in a fully expanded state, and when every two adjacent connecting members are close to each other to overlap or mostly overlap, the telescopic structure is in a fully contracted state; and the telescopic mechanism also comprises a fixing mechanism for keeping the telescopic mechanism in the expanded state (even if the two adjacent connecting members are kept away from each other); the stool surface 1 is connected to a connecting member 3 at the top of the telescopic mechanism, and the stool bottom 2 is connected to a connecting member 3 at the bottom of the telescopic structure; wherein, the first transition mechanism is used to connect the stool surface 1 with the telescopic mechanism, and the second transition mechanism is used to connect the stool bottom 2 with the telescopic mechanism.

[0081] Specifically, the fixing mechanism includes a first limiting structure for providing axial limiting for the connecting member 3 and a second limiting structure for providing circumferential limiting for the connecting member 3; wherein the first limiting mechanism includes a first limiting portion 31 provided on the connecting member 3 and a second limiting portion 32 cooperating with the first limiting portion 31 on the adjacent connecting member 3; the first limiting portion is formed by extending outward from at least part of the inner wall of the connecting member 3, and the second limiting portion is formed by extending outward from at least part of the outer wall of the connecting member 3; when the telescopic mechanism is in the expanded state, the second limiting portion 32 is located above the first limiting portion 31, and the first limiting portion 31 plays an axial supporting role for the second limiting portion 32, so as to prevent the upper connecting member from shrinking into the next connecting member, so that the two adjacent connecting members maintain a relatively expanded state.

[0082] Furthermore, a first movable area 33 for allowing a second limiting portion 32 on an adjacent connecting member to move and a second movable area 34 connected to the first movable area 33 are provided on the connecting member 3; at least part of the inner wall of the connecting member extends outward to form a first flange 35 and a second flange 36; at least part of the upper edge of the inner wall of the connecting member extends outward to form a third flange 37; the first flange, the second flange and the third flange are arranged to form an inverted "U" shape structure, and the first movable area 33 is formed between the first flange, the second flange and the third flange; the second movable area 34 is located above the first limiting portion 31 and is connected to the first movable area; the second limiting portion 32 can move in the first and second movable areas on the adjacent connecting member, so as to facilitate the switching of the telescopic mechanism between the expanded state and the retracted state.

[0083] Furthermore, the second limiting structure includes a first inclined surface 311 provided on the first limiting portion 31 and a second inclined surface 322 provided on the second limiting portion 32. The first inclined surface 311 is inclined from top to bottom, with a side close to the first activity zone being higher and a side away from the first activity zone being lower. The first inclined surface 311 is matched with the second inclined surface 322 on the adjacent connecting member 3, so that when the first inclined surface 311 and the second inclined surface collide with each other due to external force, the downward external force will give the connecting member a circumferential force under the action of the two inclined surfaces, and the force makes the second limiting portion 32 on the connecting member tend to move away from the first activity zone, thereby making the two adjacent connecting members able to remain in the expanded state, and will not accidentally shrink due to twisting, so as to achieve higher safety.

[0084] Preferably, the second limiting structure also includes a first stop portion 321 provided on the second limiting portion 32 and a second stop portion 312 cooperating with the first stop portion 321 on the adjacent connecting member 3. Through the interference between the second stop portion 312 and the first stop portion 321 on the adjacent connecting member, even if the connecting member rotates due to the action of the circumferential force, causing the second limiting portion 32 to approach the first active area, the first stop portion 321 on the second limiting portion 32 will be blocked by the second stop portion 312, so that the second limiting portion 32 cannot enter the first active area 33, further ensuring that the two adjacent connecting members can stably maintain the expanded state, making it safer and more stable to use.

[0085] In other embodiments, the first rotation-stopping portion 321 may not be provided, and the purpose of circumferential limitation may be achieved only by the interference between the end of the second limiting portion 32 and the second rotation-stopping portion 312 .

[0086] Specifically, the stool surface 1 and the stool bottom 2 are pulled away from each other, which will drive the two adjacent connecting members 3 away from each other, and the second limiting portion 32 on the upper connecting member 3 will move upward along the first active area 33 on the lower connecting member 3. After the second limiting portion 32 contacts the third convex edge 37, the stool surface 1 and the stool bottom 2 are rotated toward each other, driving the connecting member 3 to rotate, so that the two adjacent connecting members 3 rotate in opposite directions, and then the second limiting portion 32 moves away from the first convex edge 35 and enters the second active area 34. The stool surface 1 is pressed down, so that the stool surface 1 and the stool bottom 2 are close to each other, and the lower surface of the second limiting portion 32 contacts the upper surface of the first limiting portion 31, so that the telescopic mechanism is kept in the expanded state.

[0087] When the telescopic mechanism needs to be retracted, the stool surface 1 is pulled upwards so that the stool surface 1 and the stool bottom 2 move away from each other, and then the two adjacent connecting parts 3 are driven away from each other, so that the second limiting portion 32 on the previous connecting part 3 moves upwards until it conflicts with the third convex edge 37. At this time, the second limiting portion 32 is in the first active area of ​​the next connecting part. The stool surface is rotated, and the stool surface drives the two adjacent connecting parts to rotate toward each other, and then the second limiting portion 32 rotates with the connecting part to enter the first active area 33, pressing the stool surface 1 downwards. The stool surface pushes the connecting part to move downward, so that the multiple connecting parts contract with each other into a running ring until the stool surface 1 conflicts with the stool bottom 2. At this time, the telescopic mechanism is in a retracted state.

[0088] Furthermore, a third limiting portion 38 is provided on the connecting member 3. The third limiting portion is formed by extending outward from at least part of the outer wall of the connecting member 3, and its cross-section is arranged in a trapezoidal structure and is arranged along the circumferential direction of the connecting member. Its circumferential length is much larger than its width and thickness. When the telescopic mechanism is in a retracted state, the third limiting portion 38 on the upper connecting member 3 is supported on the third convex edge 37 of the lower connecting member, so that the upper connecting member 3 will not detach from the bottom of the lower connecting member, thereby maintaining the stability of the connection between the two adjacent connecting members. A third inclined surface 381 is provided on the upper surface of the third limiting portion 38, which makes assembly more convenient and labor-saving.

[0089] Furthermore, the connecting member 3 is provided with a third active area 39 and a fourth limiting portion 40 that cooperates with the third active area 39 on the adjacent connecting member 3; at least part of the inner wall of the connecting member 3 extends outward to form a fourth convex edge 41 and a fifth convex edge 42, and the third active area 39 is an inverted "U"-shaped space surrounded by the fourth convex edge 41, the fifth convex edge 42 and the third convex edge 37; the fourth limiting portion 40 is formed by extending outward from at least part of the outer wall of the connecting member 3, and is opened in an "M"-shaped structure, and the fourth limiting portion 40 can move back and forth in the third active area 39 on the adjacent connecting member 3; the width of the fourth limiting portion 40 is The width of the fourth limit portion 40 is smaller than the width of the third active area 39, so that when the second limit portion 32 moves back and forth between the first active area 33 and the second active area 34, the fourth limit portion 40 can move back and forth in the third active area 39 without affecting the circumferential movement of the second limit portion; and the width of the fourth limit portion 40 is larger than the width of the first active area 33, so that the fourth limit portion cannot enter the first active area. Subsequently, during assembly, the staff can align the fourth limit portion with the third active area and the second limit portion with the first active area by feel alone, thereby achieving rapid installation and improving assembly efficiency, thereby improving production efficiency.

[0090] In other embodiments, the fourth limiting portion 40 may also be provided in other shapes, such as an "I" shape, an inverted "U" shape, etc., as long as the width of the fourth limiting portion is greater than the width of the first active area 33 and less than the width of the third active area 39, it ensures that the connecting parts can be easily connected to each other without affecting the linear relative movement of the connecting parts.

[0091] Preferably, a sixth convex edge 43 is further provided on the connecting member 3. The sixth convex edge is formed by extending outward from at least a portion of the inner surface of the connecting member and is connected to the first limiting portion 31 to support the first limiting portion 31 and enhance the structural strength.

[0092] Specifically, the stool surface 1 includes an upper stool body 10, an upper handle 11 and an upper connecting portion 12; the stool bottom 2 includes a lower stool body 20, a lower handle 21 and a lower connecting portion; the upper stool body 10 and the lower stool body 20 are both arranged in a circular structure, and the two have the same diameter; at least a portion of the lower surface of the outer edge of the upper stool body extends downward to form an upper stool edge 101, and a stool groove is formed on the upper stool edge; at least a portion of the upper surface of the outer edge of the lower stool body extends outward to form a lower stool edge 201, and the lower stool edge is just embedded in the stool groove, so that the two can better fit together, which is convenient for the telescopic stool to be in a retracted state storage; at least part of the surface of the middle part of the upper stool body 10 is recessed downward to form an upper groove 13, and the upper handle 11 is just embedded in the upper groove 13. In this embodiment, the two are connected by a snap-fit ​​connection; at least part of the surface of the middle part of the lower stool body 20 is recessed upward to form a lower groove 23, and the lower handle 21 is just embedded in the lower groove 23. In this embodiment, the two are connected by a snap-fit ​​connection; a plurality of reinforcing ribs are provided on the lower surface of the upper stool body 10 and the upper surface of the lower stool body 20, and the plurality of reinforcing ribs are arranged in a spider web structure to enhance the structural strength of the upper stool body and the lower stool body.

[0093] Furthermore, the upper handle 11 is arranged in a circular structure, and is provided with three upper through grooves 111, and the upper groove portion 13 is provided with grooves corresponding to the upper through grooves, so as to facilitate the user to grasp the stool surface 1; the upper connecting portion 12 is installed in the middle of the lower surface of the upper handle 11, and is provided with a through hole; the structure of the lower handle 21 is the same as that of the upper handle 11, and the lower groove portion is provided with a groove corresponding to the lower through groove, and the lower connecting portion is installed in the middle of the upper surface of the lower handle 21, corresponding to the upper connecting portion, and has the same structure, and is also provided with a through hole; the two ends of the spring are respectively connected to the through holes on the upper and lower connecting portions, which are used to maintain the interference state between the stool surface 1 and the stool bottom 2, and the upper stool body 10 and the lower stool body 20 are provided with through holes for the spring to pass through.

A telescopic stool, comprising a stool surface (1), a stool bottom (2), a telescopic mechanism and a first transition mechanism for connecting the stool surface (1) and the telescopic mechanism, the first transition mechanism comprising an upper transition portion (15) provided on the stool surface (1) and a first transition piece (61) matched with the upper transition portion (15); characterized in that: The telescopic mechanism can be switched between an expanded state and a contracted state, and comprises a plurality of relatively movable connecting members (3) and a fixing mechanism arranged on the connecting members (3), the fixing mechanism being used to keep the telescopic mechanism in the expanded state; The fixing mechanism comprises a first limiting structure for providing axial limiting for the connecting member (3); The first limiting structure comprises a first limiting portion (31) provided on the connecting member (3) and a second limiting portion (32) matched with the first limiting portion (31) on an adjacent connecting member (3); The fixing mechanism further comprises a second limiting structure for providing circumferential limiting for the connecting member (3); The second limiting structure comprises a first inclined surface (311) provided on the first limiting portion (31) and a second inclined surface (322) provided on the second limiting portion (32), wherein the first inclined surface (311) matches the second inclined surface (322) on the adjacent connecting member (3); The second position-limiting structure further comprises a first rotation-stopping portion (321) provided on the second position-limiting portion (32) and a second rotation-stopping portion (312) matched with the first rotation-stopping portion (321) on the adjacent connecting member (3); The fixing mechanism further comprises a third limiting structure for providing radial limiting for the connecting member (3); The third limiting structure comprises a fifth limiting portion (323) provided on the connecting member (3) and a sixth limiting portion (313) matched with the fifth limiting portion (323) on the adjacent connecting member (3); The first limiting portion is formed by extending outwards at least a portion of the inner wall of the connecting member (3), and the second limiting portion is formed by extending outwards at least a portion of the outer wall of the connecting member (3); When the telescopic mechanism is in an expanded state, the second limiting portion (32) is located above the first limiting portion (31), and the first limiting portion (31) plays an axial supporting role for the second limiting portion (32), thereby preventing the upper connecting member from shrinking into the lower connecting member, so that the two adjacent connecting members are kept in a relatively expanded state; A first movable area (33) for allowing a second limiting portion (32) on an adjacent connecting member to move and a second movable area (34) connected to the first movable area (33) are provided on the connecting member (3); at least part of the inner wall of the connecting member extends outward to form a first convex edge (35) and a second convex edge (36); at least part of the upper edge of the inner wall of the connecting member extends outward to form a third convex edge (37); the first convex edge, the second convex edge and the third convex edge are arranged to form an inverted "U"-shaped structure, and the first movable area (33) is formed between the first convex edge, the second convex edge and the third convex edge; the second movable area (34) is located above the first limiting portion (31) and is connected to the first movable area; the second limiting portion (32) can move within the first movable area and the second movable area on the adjacent connecting member, so as to facilitate the telescopic mechanism to switch between an expanded state and a contracted state; The second limiting structure comprises a first inclined surface (311) provided on the first limiting portion (31) and a second inclined surface (322) provided on the second limiting portion (32); the first inclined surface (311) is inclined from top to bottom, with a side close to the first activity zone being higher and a side away from the first activity zone being lower; the first inclined surface (311) is matched with the second inclined surface (322) on the adjacent connecting member (3), so that when the first inclined surface (311) and the second inclined surface collide with each other due to external force, the downward external force will give the connecting member a circumferential force under the action of the two inclined surfaces, and this force makes the second limiting portion (32) on the connecting member tend to move away from the first activity zone, thereby enabling the two adjacent connecting members to remain in an expanded state and not accidentally shrink due to twisting, thereby achieving higher safety; The second limiting structure also includes a first stop portion (321) provided on the second limiting portion (32) and a second stop portion (312) matched with the first stop portion (321) on the adjacent connecting member (3). Through the interference between the second stop portion (312) and the first stop portion (321) on the adjacent connecting member, even if the connecting member rotates due to the circumferential force, causing the second limiting portion (32) to approach the first active area, the first stop portion (321) on the second limiting portion (32) will be blocked by the second stop portion (312), so that the second limiting portion (32) cannot enter the first active area (33), further ensuring that the two adjacent connecting members can stably maintain the unfolded state, making it safer and more stable to use.
