[0008] Optionally, in the pot lid according to the present invention, the latch includes a core body, and the locking member further includes an operating member disposed above the latch. The operating member includes a pressing convex portion. When the operating member rotates, it is adapted to drive the pressing convex portion to rotate until it abuts against the latch so that the core body is latched with the positioning groove, or to deviate and release the latch so that the core body is disengaged from the positioning groove.

[0009] Optionally, in the pot lid according to the present invention, the operating member further includes a rotating operating handle. The pressing convex portion is an arc-shaped convex block protruding from the handle, and the arc-shaped convex block is adapted to push the latch to move as the handle rotates.

[0010] Optionally, in the pot lid according to the present invention, the latch further includes an elastic member. The elastic member is sleeved on the core body, and the elastic member elastically abuts against the core body and the inner wall of the locking member.

[0011] Optionally, in the pot lid according to the present invention, a threaded groove is provided at the upper end of the central column. The connecting member extends into the threaded groove and is threadedly connected to the threaded groove.

[0012] Optionally, in the pot lid according to the present invention, a limiting post is further provided on the cover body. An arc-shaped groove is provided on the support member and is adapted to cooperate with the limiting post.

[0031] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0032] Figure 1 and Figure 2 Shows a structural schematic diagram of a pot lid 400 in a locked state according to an embodiment of the present invention; Figure 3 and Figure 4 Shows a structural schematic diagram of the pot lid 400 when the lock catch 310 is disengaged from the positioning groove 321 according to an embodiment of the present invention; Figure 5 and Figure 6 Shows a structural schematic diagram of the pot lid 400 in an unlocked state according to an embodiment of the present invention.

[0033] As Figures 1 to 6As shown, the pot lid 400 includes a lid body 100, a support member 200, and a locking member 300. The support member 200 is located above the pot lid 400 and is detachably mounted on the top surface of the lid body 100. The lid body 100 can rotate relative to the support member 200, and the locking member 300 is detachably connected to the lid body 100. During actual application, both ends of the support member 200 are fixedly connected to the pot body. By operating the lid body 100 to rotate relative to the pot body and the support member 200, the lid body 100 can be opened or locked relative to the pot body.

[0034] According to one embodiment, as Figure 2 , Figure 4 and Figure 6 shown, a central column 150 is provided at the center of the lid body 100, and a central hole 250 is provided at the center of the support member 200. Among them, the support member 200 is sleeved on the central column 150 through the central hole 250, and the width of the central hole 250 is greater than the width of the central column 150. Therefore, there is still a certain accommodation space between the central hole 250 and the central column 150, so that the locking member 300 can be sleeved on the central column 150 and accommodated in the central hole 250. It can be understood that when the locking member 300 is not installed, the central column 150 can move relative to the central hole 250, and the support member 200 can be disengaged from the central column 150 upward through the central hole 250, so that the support member 200 can be separated from the lid body 100.

[0035] Among them, as Figure 2 shown, the locking member 300 is detachably installed in the central hole 250 and is fixedly connected to the central column 150. The upper end of the locking member 300 has a step portion 354. Through this step portion 354, the upward movement of the support member 200 can be restricted, thereby preventing the support member 200 from being separated from the lid body 100 and locking the support member 200 on the lid body 100. In this locked state, since the locking member 300 is fixed to the lid body 100, and both the central column 150 and the locking member 300 are located in the central hole 250, the central column 150 and the locking member 300 can be rotated in the central hole 250 by rotating the lid body 100. That is to say, when taking the lid body 100 as a reference, the locking member 300 is stationary, and the central hole 250 of the support member 200 rotates relative to the central column 150 and the locking member 300. Therefore, after the locking member 300 is installed, the support member 200 and the lid body 100 cannot be separated from each other, and the support member 200 can only rotate relative to the center of the lid body 100. In addition, as Figure 5 and Figure 6 shown, when unlocking the pot lid 400, by disassembling and separating the locking member 300 from the central column 150 and taking out the locking member 300 from the central hole 250, the support member 200 can be disengaged from the central column 150 upward through the central hole 250. Thus, the support member 200 can be separated from the lid body 100, which is the unlocked state of the support member 200 and the lid body 100.

[0036] Further, as shown in Figure 2 and Figure 4 , the locking member 300 includes a connecting member 351 which is adapted to be fixedly connected to the central column 150. Among them, a threaded groove 151 is formed at the upper end of the central column 150. The side wall of the connecting member 351 is provided with an external thread that mates with the threaded groove 151. In this way, the connecting member 351 can extend into the threaded groove 151 and rotate to be threadedly connected to the threaded groove 151, so that the connecting member 351 and the central column 150 are fixedly connected by threads.

[0037] Furthermore, as shown in Figure 2 and Figure 4 , a positioning groove 321 is provided along the axial direction in the central hole 250. The locking member 300 further includes a lock catch 310. Among them, a receiving groove 337 is provided above the positioning groove 321 in the locking member 300, and the receiving groove 337 communicates with the positioning groove 321. The lock catch 310 is slidably installed in the receiving groove 337. By pressing the lock catch 310, the lock catch 310 can slide along the receiving groove 337, that is, move in the direction close to or away from the positioning groove 321, so as to move to be latched or disengaged from the positioning groove 321. Here, when the lock catch 310 is latched with the positioning groove 321 by operation, the rotation of the locking member 300 relative to the central column 150 can be restricted, thereby preventing the threaded groove 151 of the connecting member 351 and the central column 150 from being accidentally unscrewed, and strengthening the stability of the connection between the locking member 300 and the central column 150 in the locked state.

[0038] It can be understood that when unlocking the pot lid 400, it is necessary to first disengage the lock catch 310 from the positioning groove 321 through operation, as shown in Figure 4 ; then rotate the locking member 300 to unscrew and separate the connecting member 351 from the threaded groove 151, so that the locking member 300 can be taken out of the central hole 250, as shown in Figure 6 .

[0039] Specifically, as shown in Figure 2 , Figure 4 and Figure 6 , the locking member 300 further includes a hollow column 350 with a hollow structure and a positioning sleeve 320. As shown in Figure 7b and Figure 7c , a head 353 is formed by the top of the hollow column 350 extending upward. Among them, the hollow column 350 is inserted into the central hole 250 and sleeved outside the central column 150, and there is a spaced space between the hollow column 350 and the central column 150. The connecting member 351 extends downward from the head 353 into the cavity of the hollow column 350 and is coaxially arranged with the hollow column 350, so that the connecting member 351 can extend into the threaded groove 151 of the central column 150 and be threadedly fixed to it.

[0040] As shown inFigure 6 As shown, the positioning sleeve 320 is provided with a central axis hole 325 penetrating along the axial direction. The positioning sleeve 320 is sleeved on the central column 150 through the central axis hole 325, and the outer wall of the positioning sleeve 320 abuts against the inner wall of the hollow column 350. Thus, the positioning sleeve 320 can be stably installed in the central hole 250 and fixed within the hollow column 350. Here, the positioning sleeve 320 and the hollow column 350 are of a split structure and can be separated from each other. The positioning sleeve 320 can be individually sleeved on the central column 150 and can also be disassembled and detached from the central column 150. As Figure 8 shown, the outer wall of the positioning sleeve 320 is recessed inward to form the above-mentioned positioning groove 321. Therefore, the positioning groove 320 is located within the hollow column 350.

[0041] As Figure 7b and Figure 7c shown, the head 353 is provided with the above-mentioned receiving groove 337 penetrating through it, and the upper end of the receiving groove 337 is open. The lower end of the receiving groove 337 communicates with the hollow column 350 through a through hole. Thus, by pressing the lock 310, the lock 310 slides along the receiving groove 337 and extends through the through hole into the positioning groove 321 located within the hollow column 350, so as to be latched with the positioning groove 321.

[0042] In addition, as Figure 7b and Figure 7c shown, the head 353 horizontally extends outward to form the above-mentioned stepped portion 354. The top of the support member 200 extends downward to form a stop portion 240. By stopping the stop portion 240 against the outer wall of the stepped portion 354, the upward movement and separation of the support member 200 relative to the cover body 100 are restricted.

[0043] According to one embodiment, as Figure 7b and 7c shown, the lock 310 includes a core body 311, a lock head 353, and an elastic member 313. The core body 311 can be formed by the lock head 353 extending downward. Among them, by pressing the lock head 353 for operation, the lock 310 moves relative to the receiving groove 337. Thus, the core body 311 can extend downward into the positioning groove 321 and be latched with the positioning groove 321. In addition, the elastic member 313 is sleeved on the core body 311, and the elastic member 313 elastically abuts between the lock 310 and the inner wall of the receiving groove 337. The elastic member 313 can be a spring, but is not limited thereto.

[0044] Specifically, as Figure 7c and Figure 7dAs shown, the lock head 353 can be a cylindrical cavity with one end open. The core 311 extends downward from the top wall of the lock head 353, and the lower end of the core 311 protrudes downward outside the lock head 353. The two ends of the elastic member 313 respectively abut against the top wall of the lock head 353 and the inner wall of the receiving groove 337. When the lock head 353 is pressed downward, the elastic member 313 will be squeezed, and the core 311 will be driven to move downward until it extends into the positioning groove 321 and is latched with it, as Figure 2 shown. At this time, the lock head 353 abuts against the inner wall of the receiving groove 337, thereby restricting the lock catch 310 from moving downward further.

[0045] It can be understood that when the lock head 353 is no longer pressed, the elastic restoring force of the squeezed elastic member 313 can push the lock head 353 and the core 311 to move upward together, so that the core 311 disengages from the positioning groove 321, as Figure 4 shown.

[0046] According to one embodiment, as Figure 2 and Figure 7c shown, the locking member 300 further includes an operating member 330. The operating member 330 is installed on the top of the head 353, and the operating member 330 is arranged above the lock catch 310, so as to be able to abut against the lock head 353 of the lock catch 310. Among them, as Figure 7b shown, the operating member 330 includes an arc-shaped pressing convex portion 332. The pressing convex portion 332 is located at a position opposite to the receiving groove 337, so as to be able to cooperate with and abut against the lock catch 310 in the receiving groove 337. Specifically, by operating to rotate the operating member 330, the pressing convex portion 332 is driven to rotate until it abuts against the lock head 353 of the lock catch 310, so that the lock catch 310 moves along the receiving groove 337 in the direction close to the positioning groove 321, so that the lock catch 310 extends into the positioning groove 321 and is latched with it. In addition, the pressing convex portion 332 can also rotate to deviate from the lock head 353, so as to release the lock catch 310.

[0047] Furthermore, as Figures 7b to 7d shown, the operating member 330 further includes a handle 333. The handle 333 can be latched on the top of the stepped portion 354. The handle 333 is arc-shaped, for example, it can be a semi-circular rod shape. The two ends of the handle 333 horizontally extend inward to form a rotating shaft 331. Here, "inward" means in the direction close to the opposite end. Among them, the rotating shaft 331 can be fixed at the top position of the head 353 and is horizontally arranged directly above the receiving groove 337. In this way, by pulling up or pressing down the handle 333, the handle 333 and the rotating shaft 331 can both rotate around the axis of the rotating shaft 331, that is, the rotating shaft 331 rotates by itself.

[0048] The above-mentioned pressing protrusion 332 is an arc-shaped protrusion protruding from the rotation shaft 331 of the handle 333. Specifically, it protrudes away from the axis of the rotation shaft 331 and towards the handle 333, and the plane where the arc-shaped protrusion is located is perpendicular to the plane where the handle 333 is located. In this way, when the handle 333 is operated to rotate, the rotation shaft 331 rotates on its own axis, and the arc-shaped protrusion can rotate along with the handle 333 and the rotation shaft 331, thereby pushing the lock 310 to move along the receiving groove 337.

[0049] According to one embodiment, as Figure 7b shown, the pressing protrusion 332 can be a semi-circular protrusion protruding from the rotation shaft 331.

[0050] Specifically, as Figure 7d shown, when the handle 333 is in the vertical position, the pressing protrusion 332 rotates above the rotation shaft 331, so that the pressing protrusion 332 does not abut against the lock 310 in the receiving groove 337. At this time, the lock 310 is disengaged from the positioning groove 321. When the handle 333 is pressed downward to rotate from the vertical position to the horizontal position, the pressing protrusion 332 rotates from above the rotation shaft 331 to a position where a part of it is below the rotation shaft 331. During this process, the pressing protrusion 332 can abut against the locking head 353 of the lock 310, causing the lock 310 to move vertically downward along the receiving groove 337, so that the core body 311 extends into the hollow cylinder 350 and is latched in the positioning groove 321, as Figure 7c and Figure 2 shown. Through the above settings, by operating the handle 333 to drive the pressing protrusion 332 to rotate until it abuts against the lock 310 and moves, the core body 311 moves into the positioning groove 321 and is latched with it, thereby restricting the rotation of the locking member 300 relative to the central column 150 and preventing the locking member 300 from being unscrewed from the central column 150 due to misoperation.

[0051] In addition, when the handle 333 rotates from the horizontal position to the vertical position, since the pressing protrusion 332 no longer abuts against the lock 310, the lock 310 is released. At this time, the elastic restoring force of the elastic member 313 can push the locking head 353 and the core body 311 to move upward along the receiving groove 337, so that the core body 311 can be disengaged from the positioning groove 321, as Figure 4 and Figure 7d shown. At this time, the locking member 300 can be rotated to be unscrewed from the central column 150.

[0052] Through the above settings, as Figure 1 and Figure 2As shown, the locking member 300 is received in the central hole 250. By rotating the locking member 300, the connecting member 351 is threadedly and fixedly connected to the central column 150. The operating handle 333 is rotated to the horizontal position so that the lock 310 is snapped into the positioning groove 321, thereby restricting the locking member 300 from rotating in the opposite direction relative to the central column 150 and unscrewing, which can avoid misoperation and firmly lock the support member 200 and the cover body 100.

[0053] According to one embodiment, as Figure 8 shown, a plurality of the above-mentioned positioning grooves 321 are formed by inwardly recessing the outer wall of the positioning sleeve 320. Each positioning groove 321 extends from the top to the bottom of the positioning sleeve 320 along the axial direction, and the plurality of positioning grooves 321 are uniformly arranged along the circumferential direction of the positioning sleeve 320, which facilitates aligning any one of the positioning grooves 320 with the position of the core body 311 after the positioning sleeve 320 is installed. Specifically, the positioning groove 321 is formed by first inwardly recessing the outer wall of the positioning sleeve 320 along an inclined surface to form a notch, and then further inwardly recessing along an arc surface. In this way, the mouth of the positioning groove 321 is in an expanded arc shape, which is more conducive to the core body 311 sliding into the positioning groove 321 and snapping.

[0054] In addition, a gap is provided between two adjacent positioning grooves 321, and they are not connected. Thus, after the entire locking member 300 is installed in the central hole 250 and the connecting member 351 is threadedly connected to the threaded groove 151, the outer wall (the non-recessed part) of the positioning sleeve 320 abuts against the inner wall of the hollow cylinder 350, so that the side wall of the positioning groove 321 is relatively sealed, ensuring that the core body 311 of the lock 310 can be stably snapped in the positioning groove 321 and will not disengage from the side of the positioning groove 321.

[0055] According to one embodiment, as Figures 7a to 7d shown, the locking member 300 further includes a fixed cover 340, and the fixed cover 340 covers the upper part of the head 353. The handle 333 can be looped around the outer periphery of the fixed cover 340 and thus can rotate above the fixed cover 340 around the fixed cover 340. The rotating shaft 331, the pressing convex part 332 and the lock 310 are all located below the fixed cover 340 and are thus blocked by the fixed cover 340, making the overall appearance of the locking member 300 more beautiful.

[0056] According to one embodiment, as Figure 2 、 Figure 4 and Figure 6As shown, the support member 200 includes a fixing portion 280 at the lower end and a top cover 290 that is snap-connected to the top surface of the fixing portion 280, and an accommodation space is formed between the top cover 290 and the fixing portion 280. A through hole is formed in the top cover 290 to facilitate the exposure of the handle 333 and the fixing cover 340. The fixing cover 340 protrudes out of the support member 200 through the through hole of the top cover 290, and when the handle 333 rotates to form an angle with the horizontal position, it also protrudes out of the support member 200. Thus, by operating the handle 333, the pressing protrusion 332 is driven to abut against the locking buckle 310 to move, so that the locking buckle 310 can be snap-connected to or disengaged from the positioning groove 321.

[0057] Specifically, as Figure 6 shown, a stop portion 240 that cooperates with the step portion 354 is provided extending downward at the through hole of the top cover 290. When the locking member 300 is installed in the central hole 250, as Figure 2 shown, the stop portion 240 can stop against the outer wall of the step portion 354, so that the support member 200 cannot move upward relative to the cover body 100 and thus cannot be separated from the cover body 100.

[0058] In addition, in an embodiment according to the present invention, as Figures 1 to 6 shown, two limiting columns 110 are symmetrically provided on the cover body 100 relative to the center of the cover body 100. Correspondingly, two arc-shaped grooves that cooperate with the limiting columns 110 are symmetrically provided on the support member 200 relative to the center of the support member 200. When the cover body 100 rotates relative to the support member 200, the limiting columns 110 are driven to slide along the arc-shaped grooves. Among them, the arc-shaped grooves include ends with relatively larger widths. Specifically, the width of any end of the arc-shaped groove is greater than the cross-sectional width of the top of the limiting column 110, and the width of the remaining part of the arc-shaped groove except this end is less than the cross-sectional width of the top of the limiting column 110. Thus, when the cover body 100 rotates relative to the support member 200, the limiting columns 110 are driven to slide relative to the arc-shaped grooves, and when sliding to the end with the larger width, they can disengage from the arc-shaped grooves at this end, that is, the support member 200 can be disengaged from the limiting columns 110 upward through the arc-shaped grooves.

[0059] When it is necessary to disassemble and wash the pot lid 400, by rotating the cover body 100 to rotate the cover body 100 relative to the center of the support member 200, the limiting columns 110 are simultaneously driven to slide relative to the arc-shaped grooves, and the limiting columns 110 are made to slide along the arc-shaped grooves to the end with the larger width. At this time, by operating the handle 333 to rotate to the vertical position, as Figure 4 shown, the locking buckle 310 disengages from the positioning groove 321 and no longer restricts the rotation of the locking member 300. Then, by rotating the locking member 300 to unscrew it from the central column 150, the locking member 300 can be taken out of the central hole 250, as Figure 6As shown, the locking member 300 no longer presses against the support member 200. In this way, the support member 200 can be disengaged from the central column 150 upward through the central hole 250, and the end with a larger width of the arc-shaped groove can also be disengaged from the limiting post 110. Therefore, the support member 200 can be disassembled from the cover body 100 for cleaning the pot lid 400. Here, during the process of disassembling the pot lid 400, the cooperation between the limiting post 110 and the arc-shaped groove plays a guiding role in the relative rotation of the cover body 100 and the support member 200, and can assist in the disassembly and separation of the support member 200 and the cover body 100.

[0060] Further, in order to make it more convenient to disassemble the support member 200 and the cover body 100, as Figure 1 、 Figure 3 and Figure 5 shown, the above-mentioned arc-shaped groove includes a first-stage guiding groove 210 and a second-stage offset groove 215 that is smoothly connected to the guiding groove 210 at the first end. It should be noted that the width of the guiding groove 210 is smaller than the cross-sectional width of the top of the limiting post 110, so as to stop at the top of the limiting post 110, while the width of the offset groove 215 is larger than the cross-sectional width of the top of the limiting post 110, so as to be disengaged from the limiting post 110 upward.

[0061] Specifically, as Figure 9 and Figure 10 shown, the limiting post 110 includes a column body 111 and a frustum 112 located at the top end of the column body 111. A step surface is formed between the frustum 112 and the column body 111, and one end of the column body 111 away from the frustum 112 is fixedly connected to the cover body 100. The width of the guiding groove 210 is smaller than the diameter of the frustum 112, and the width of the offset groove 215 is larger than the diameter of the frustum 112. As Figure 1 、 Figure 3 and Figure 5 shown, the guiding groove 210 is in an arc-shaped strip shape, and the offset groove 215 is in an arc-shaped block shape. Through the above settings, the column body 111 of the limiting post 110 can be inserted into the guiding groove 210, and is stopped at the top surface of the guiding groove 210 by the frustum 112, that is, the guiding groove 210 is stopped below the frustum 112, so that the guiding groove 210 cannot be disengaged from the limiting post 110 upward; and since the width of the offset groove 215 is larger than the width of the frustum 112, the offset groove 215 can be disengaged from the limiting post 110 upward.

[0062] Among them, as Figure 1 and Figure 2As shown, when the support member 200 and the cover body 100 are firmly locked, when the pot cover 400 needs to be removed and washed, the cover body 100 is rotated relative to the central hole 250 of the support member 200, and the limiting column 110 is driven to slide along the guide groove 210, and can slide to the end where the guide groove 210 is connected with the offset groove 215. In this process, the guide groove 210 is stopped below the round table 112 and cannot be separated from the limiting column 110, and the sliding tracks of the two limiting columns 110 in their corresponding guide grooves 210 are symmetrical relative to the center of the support member 200.

[0063] Furthermore, if Figure 4 As shown, by rotating the operating handle 333 to a vertical position, the lock buckle 310 is disengaged from the positioning groove 321 and no longer restricts the rotation of the locking member 300, and then the locking member 300 is rotated to unscrew it from the central column 150, so that the locking member 300 is removed from the central hole 250, so that the locking member 300 no longer presses the support member 200, as shown in FIG. Figure 6 As shown. At this time, when the cover body 100 is rotated again, the support member 200 rotates eccentrically relative to the cover body 100, and drives the two limit posts 110 to deviate in the offset groove 215. Since the support member 200 can be disengaged from the limit post 110 upward through the offset groove 215, and the locking member 300 no longer restricts the upward movement of the support member 200, the support member 200 can be disengaged from the center post 150 upward through the center hole 250. Therefore, the support member 200 can be taken away upward and separated from the cover body 100. It should be noted that after disassembling and removing the locking member 300, since the support member 200 rotates eccentrically relative to the cover body 100, the offset trajectories and distances of the two limit posts 110 in their corresponding offset grooves 215 are not the same.

[0064] In addition, if Figures 1 to 6 As shown, a connecting column 130 is further provided in the region of the cover body 100 deviating from the central column 150, specifically, the connecting column 130 is provided in the region between the central column 150 and the limiting column 110. Correspondingly, a connecting hole 230 matching with the connecting column 130 is provided in the region of the support member 200 deviating from the central hole 250, as shown in FIG. Figure 1As shown, the connecting hole 230 is in an arc shape, so that the connecting column 130 can rotate relative to and slide relative to within the connecting hole 230. The support member 200 is rotatably sleeved on the connecting column 130 through the connecting hole 230 and can eccentrically rotate relative to the cover body 100 around the connecting column 130. Specifically, when the locking member 300 is installed, when the cover body 100 is rotated to make the support member 200 rotate relative to the center of the cover body 100, the connecting column 130 on the cover body 100 also rotates relative to the center of the support member 200. Since the connecting hole 230 is in an arc shape, the connecting column 130 can slide relative to within the connecting hole 230. In addition, after the locking member 300 is removed and taken out, when the cover body 100 is rotated, the support member 200 can rotate relative to the connecting column 130 through the connecting hole 230, that is, eccentrically rotate relative to the cover body 100, thereby driving the two limiting columns 110 to offset within the offset groove 215. In this embodiment, the symmetric center of the two offset grooves 215 can be set to deviate from the central column 150. For example, the symmetric center is set at the position of the connecting column 130, which is more conducive to the offset of the limiting column 110 within the offset groove 215.

[0065] It should be understood that when the pot cover 400 is disassembled, the cooperation of the above-mentioned guiding groove 210 and offset groove 215 with the limiting column 110 plays a guiding and assisting role for the support member 200 to rotate and eccentrically rotate relative to the center of the cover body 100, thereby assisting in the disassembly and separation of the support member 200 from the cover body 100.

[0066] Furthermore, Figure 1 and Figure 3 The sliding trajectory ranges of the limiting column 110 and the connecting column 130 when the support member 200 rotates relative to the center of the cover body 100 in the locked state are also shown. Their rotation angles are both rotations along y - y to x - x. When the locking member 300 is taken out and the support member 200 eccentrically rotates relative to the connecting column 130 of the cover body 100, the central column 150 offsets relative to the central hole 250, and the limiting column 110 offsets relative to the offset groove 215. The offset trajectories are as Figure 5 shown. The rotation angle is a rotation along x - x to z - z. The offset trajectories of the two limiting columns 110 within their corresponding offset grooves 215 are not the same. It can also be seen from Figure 5 that the limiting column 110 farther away from the central hole 230 has a longer offset trajectory within the offset groove 215.

[0067] Here, the rotation angles and sliding trajectories of the limiting column 110 and the connecting column 130 can be adjusted through a gear assembly. Their rotation angles can be set to be the same or different, which will not be listed one by one here.
