Description

Technical Field

[0001] This invention relates to the field of road construction safety technology, specifically to adjustable and easily reinstallable protective equipment for road construction. Background Technology

[0002] Road construction protective equipment refers to various equipment and items used during the construction of roads and highways to protect workers from potential injuries. When working on the road surface, it is necessary to isolate the construction area with fences to prevent vehicles and pedestrians from entering, while also ensuring the safety and health of construction workers.

[0003] Road construction fences are placed around the road construction area. The fence is fixed in place by drilling holes in the road surface and inserting fence posts into the holes using expansion bolts. This requires manual support of the posts and adjustment of their relative positions to the holes, which is time-consuming and labor-intensive. Furthermore, the fence is prone to swaying in crosswinds, causing the expansion bolts at the base of the posts to loosen and affecting its stability. While placing warning signs on the fence increases its weight and stability, different warning signs are required for different construction sites, reducing the applicability of general protective equipment. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable and easily reinstallable protective device for road construction, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: Adjustable and easy-to-reinstall road construction protective equipment, including columns, stabilizing mechanisms, connecting mechanisms, partitions, and clamping mechanisms; The bottom of the column is provided with a stabilizing mechanism, the end of the column away from the stabilizing mechanism is provided with a connecting mechanism, a partition is provided on one side of the connecting mechanism, a clamping mechanism is provided on the front of the partition, and a warning sign is provided on one side of the clamping mechanism.

[0006] The stabilizing mechanism includes a connecting sleeve, the inner wall of which is fitted onto the bottom end of the column. A supporting base plate is located at the bottom of the connecting sleeve, and a through hole is formed on the upper surface of the supporting base plate. An expansion bolt is secured to the supporting base plate through the through hole. A threaded retaining ring is threaded onto the outer wall of the connecting sleeve, and a wedge-shaped retaining block is located at the bottom of the threaded retaining ring. Four transmission gears are equidistantly arranged in a ring on the outer wall of the connecting sleeve. A supporting retaining strip is secured to the upper surface of the supporting base plate. The supporting base plate is fixed in position by connecting the expansion bolt to the hole at the beginning of the construction surface. The column is then inserted into the connecting sleeve, facilitating rapid installation of the column and allowing users to quickly position it, reducing the labor required for workers to support and tighten the column.

[0007] The bottom of the threaded retaining ring has an annular groove, and the top of the wedge-shaped retaining block is connected to the inner wall of the annular groove. Four wedge-shaped retaining blocks are provided. A spring is horizontally installed at one end of the central shaft of the transmission gear. A strip-shaped groove is horizontally installed on one side of the connecting sleeve. One end of the central shaft of the transmission gear is connected to the inner wall of the strip-shaped groove. The bottom of the wedge-shaped retaining block is connected to the outer wall of the central shaft of the transmission gear. A through hole is provided on the side of the connecting sleeve near the transmission gear. A vertical rack is annularly installed at the bottom of the column. One side of the transmission gear meshes with the vertical rack through the through hole. A horizontal rack is provided on the upper surface of the support retaining strip. The bottom of the transmission gear meshes with the horizontal rack. As the column is inserted into the connecting sleeve, the vertical rack at the bottom of the column meshes with the transmission gear. The downward movement of the column drives the transmission gear to rotate, and the transmission gear pushes the support clip to move through the horizontal rack at the bottom. The support clip extends outwards along the upper surface of the support base plate, increasing the support area between the support base plate and the ground and improving the stability of the column. The threaded retaining ring rotates along the outer wall of the connecting sleeve, and the threaded retaining ring drives the wedge-shaped retaining block to move downwards. This causes the wedge-shaped retaining block to push the transmission gear to move along the strip groove, and one side of the transmission gear disengages from the engagement with the bottom of the column, making it easy for the user to disassemble the column.

[0008] The connecting sleeve has a through hole on the side near the support clip, and one end of the support clip is connected to the column through the through hole. By rotating the threaded retaining ring to move the wedge-shaped block downward, the wedge-shaped block pushes the transmission gear to disengage from the bottom of the column. Then, the support clip slides along the upper surface of the support base plate, and after the column is inserted into the bottom of the connecting sleeve, the end of the support clip near the column is moved so that the support clip fits against the bottom of the column. Then, the threaded retaining ring is rotated to move the wedge-shaped block upward, so that the transmission gear re-engages with the column. At this time, when the column is pulled up, the vertical rack at the bottom of the column drives the transmission gear to rotate. The transmission gear drives the support clip through the horizontal rack to press against the bottom of the column, so that the support clip clamps and fixes the bottom of the column, improving the stability of the column.

[0009] The connecting mechanism includes a slider connected to the inner wall of a column. A rotating rod is hinged to one side of the slider, and a retaining sleeve is hinged to one end of the rotating rod. A spring is provided at the bottom of the slider. A vertical groove is provided on the side of the column near the slider. A partition is engaged with the inner wall of the retaining sleeve. By sliding the slider along the outer wall of the column, the deflection position of the rotating rod is adjusted, controlling the horizontal extension length of the retaining sleeve at one end of the rotating rod. By deflecting the retaining sleeve along one end of the rotating rod, the connection angle between the partition and the retaining sleeve is adjusted. After connecting one side of the partition, the other side of the partition is connected to the connecting mechanism on another column. The rotating rod is pressed down synchronously along the vertical groove to adjust the vertical height of the retaining sleeve, reducing the need for adjustment of the overall position of the partition and facilitating the installation of the partition by the user.

[0010] The partition includes a clamping rod, one end of which is connected to a retaining sleeve. A rectangular frame is provided on one side of the clamping rod, and a protective net is provided on one side of the rectangular frame. An anti-theft sleeve and a fastening nut are sequentially provided at the bottom of the clamping rod. The anti-theft sleeve is sleeved with the clamping rod, and the fastening nut is connected to the inner wall of the anti-theft sleeve. One end of the clamping rod is engaged with the inner wall of the retaining sleeve, allowing the partition to be horizontally deflected by the retaining sleeve, enabling the other side of the partition to quickly connect with the column. After the clamping rod and retaining sleeve are engaged, the positions of the clamping rod and retaining sleeve are fixed by the anti-theft sleeve and the fastening nut. The rectangular frame increases the compressive strength of the partition, and the protective net reduces the impact of crosswinds on the partition, thus improving the stability of the partition.

[0011] The clamping mechanism includes a right-angle rotating plate. One side of the right-angle rotating plate is connected to a rectangular frame. A sliding buckle is provided at the top of the right-angle rotating plate. A vertical clamping plate is hinged to the front of the sliding buckle. A counterweight is provided at the bottom of the vertical clamping plate. A horizontal clamping plate is provided at the bottom of the right-angle rotating plate. The vertical clamping plate is connected to one side of the warning sign, and the horizontal clamping plate is connected to the bottom of the warning sign. A toothed rod is provided on the back of the right-angle rotating plate, and a transmission gear set is provided at one end of the toothed rod. When the warning sign is lowered along one side of the right-angle rotating plate, the horizontal clamping plate first supports the bottom of the warning sign. The horizontal clamping plate is subjected to downward pressure, causing the right-angle rotating plate to deflect along the hinge point with the rectangular frame. This causes the vertical clamping plate at the other end of the right-angle rotating plate to clamp the side of the warning sign, thereby fixing the position of the warning sign. When the warning sign is pulled upward, the horizontal clamping plate releases the downward pressure and simultaneously releases the clamping of the vertical clamping plate on the side of the warning sign, making it convenient for the user to install and remove the warning sign.

[0012] A central rotating rod is provided on the back of the right-angle rotating plate. The central rotating rod is connected to the rectangular frame through a bearing. The transmission gear set includes a gear ring and a stepped gear. One side of the gear ring is connected to the back of the right-angle rotating plate. The center point of the gear ring coincides with the center point of the central rotating rod. The stepped gear is connected to the back of the right-angle rotating plate. The stepped gear includes a small-diameter gear and a large-diameter gear. One side of the small-diameter gear meshes with the gear ring, and one side of the large-diameter gear meshes with the gear rack. As the warning sign is placed on the horizontal clamping plate, the right-angle rotating plate deflects around the central rotating rod. Simultaneously, the right-angle rotating plate drives the gear ring to rotate, which in turn drives the meshing stepped gear to rotate. Through the differential transmission between the small-diameter and large-diameter gears of the stepped gear, the stepped gear quickly drives the rack to slide along one side of the right-angle rotating plate. The rack simultaneously drives the vertical clamping plate on the sliding buckle to move rapidly, causing the vertical clamping plate to move downwards along one side of the right-angle rotating plate. This allows the vertical clamping plate to quickly clamp the side of the warning sign, facilitating the placement of warning signs of various sizes and improving the applicability of the clamping mechanism.

[0013] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The installation of the column and stabilizing mechanism facilitates secondary installation by the staff. The support base plate and connecting sleeve are fixed in position by expansion bolts, and then the column is fitted into the inner wall of the connecting sleeve to fix the position of the column. This reduces the labor consumption of the staff in adjusting the overall position of the column. The column is fastened by the transmission gear and support clip, which facilitates the quick connection between the column and the connecting sleeve and improves the work efficiency of the staff.

[0014] 2. The stability of this device is improved by the arrangement of the column, stabilizing mechanism, connecting mechanism, and partition. The support strip increases the support area between the bottom of the column and the ground, preventing the column from tipping over. The clamping sleeve drives the rotating rod to deflect, reducing the impact of crosswinds on the partition and column. The partition causes the column to sway through the connecting mechanism. The column sways and deflects along the inner wall of the connecting sleeve. The vertical rack at the bottom of the column in the tilting direction drives the transmission gear at the bottom to rotate, which further pushes the support strip to extend, increasing the contact area between the bottom of the column in the tilting direction and the ground, ensuring the stability of the column.

[0015] 3. The partition and clamping mechanism facilitate the placement of warning signs of various sizes and make the device easy to adjust. When the warning sign is placed on the horizontal clamping plate, the right-angle rotating plate deflects around the central rotating rod. The right-angle rotating plate simultaneously drives the gear ring to rotate, which in turn drives the meshing stepped gear to rotate. Through the differential transmission between the small-diameter and large-diameter gears of the stepped gear, the stepped gear quickly drives the rack to slide along one side of the right-angle rotating plate. The rack simultaneously drives the vertical clamping plate on the sliding buckle to move quickly, causing the vertical clamping plate to move downward along one side of the right-angle rotating plate. This allows the vertical clamping plate to quickly clamp the side of the warning sign, making it convenient for users to place warning signs of various sizes. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9 The present invention provides the following technical solution: Adjustable and easy-to-install road construction protective equipment, including column 1, stabilizing mechanism 2, connecting mechanism 3, partition 4 and clamping mechanism 5; A stabilizing mechanism 2 is provided at the bottom of the column 1. A connecting mechanism 3 is provided at the end of the column 1 away from the stabilizing mechanism 2. A partition 4 is provided on one side of the connecting mechanism 3. A clamping mechanism 5 is provided on the front of the partition 4. A warning sign 6 is provided on one side of the clamping mechanism 5.

[0020] The stabilizing mechanism 2 includes a connecting sleeve 201, the inner wall of which is fitted to the bottom end of the column 1. A support base plate 202 is provided at the bottom of the connecting sleeve 201, and a through hole is opened on the upper surface of the support base plate 202. An expansion bolt 203 is snapped into the support base plate 202 through the through hole. A threaded retaining ring 204 is threadedly connected to the outer wall of the connecting sleeve 201, and a wedge-shaped retaining block 205 is provided at the bottom of the threaded retaining ring 204. Four transmission gears 206 are equidistantly arranged in a ring on the outer wall of the connecting sleeve 201. A support retaining strip 207 is snapped into the upper surface of the support base plate 202. The support base plate 202 is fixed in position by connecting to the hole at the beginning of the construction road surface with the expansion bolt. Then, the column 1 is inserted into the connecting sleeve 201, which facilitates the quick installation of the column 1 and allows the user to quickly position the column 1, reducing the labor consumption of workers in supporting and tightening the column.

[0021] The bottom of the threaded retaining ring 204 has an annular groove. The top of the wedge-shaped retaining block 205 is connected to the inner wall of the annular groove. There are four wedge-shaped retaining blocks 205. A spring is horizontally installed at one end of the central shaft of the transmission gear 206. A strip-shaped groove is horizontally installed on one side of the connecting sleeve 201. One end of the central shaft of the transmission gear 206 is connected to the inner wall of the strip-shaped groove. The bottom of the wedge-shaped retaining block 205 is connected to the outer wall of the central shaft of the transmission gear 206. A through hole is opened on the side of the connecting sleeve 201 near the transmission gear 206. A vertical rack is annularly installed at the bottom of the column 1. One side of the transmission gear 206 meshes with the vertical rack through the through hole. A horizontal rack is installed on the upper surface of the support strip 207. The bottom of the transmission gear 206 meshes with the horizontal rack. As the column 1 is inserted into the connecting sleeve 201, the vertical rack at the bottom of the column 1 meshes with the transmission gear 206. The downward movement of the column 1 drives the transmission gear 206 to rotate. The transmission gear 206 pushes the support clip 207 to move through the horizontal rack at the bottom. The support clip 207 extends outwards along the upper surface of the support base plate 202, increasing the support area between the support base plate 202 and the ground, thus improving the stability of the column 1. The threaded retaining ring 204 rotates along the outer wall of the connecting sleeve 201. The threaded retaining ring 204 drives the wedge-shaped retaining block 205 to move downwards, causing the wedge-shaped retaining block 205 to push the transmission gear 206 to move along the strip groove. One side of the transmission gear 206 disengages from the meshing engagement with the bottom of the column 1, making it easier for the user to disassemble the column 1.

[0022] The connecting sleeve 201 has a through hole on the side near the support clip 207, and one end of the support clip 207 is connected to the column 1 through the through hole. After rotating the threaded retaining ring 204 to move the wedge-shaped retaining block 205 downward, the wedge-shaped retaining block 205 pushes the transmission gear 206 to disengage from the bottom of the column 1. Then, the support retaining strip 207 slides along the upper surface of the support base plate 202 to maintain the distance between it and the column 1. After the bottom of the column 1 is inserted into the connecting sleeve 201, the end of the support retaining strip 207 close to the column 1 is moved so that the support retaining strip 207 is in contact with the bottom of the column. Then, rotating the threaded retaining ring 204 to move the wedge-shaped retaining block 205 upward, the transmission gear 206 is re-engaged with the column 1. At this time, when the column 1 is pulled up, the vertical rack at the bottom of the column 1 drives the transmission gear 206 to rotate. The transmission gear 206 drives the support retaining strip 207 to press against the bottom of the column 1 through the horizontal rack, so that the support retaining strip 207 clamps and fixes the bottom of the column 1, improving the stability of the column 1.

[0023] The connecting mechanism 3 includes a slider 301, which is connected to the inner wall of the column 1. A rotating rod 302 is hinged to one side of the slider 301, and a retaining sleeve 303 is hinged to one end of the rotating rod 302. A spring is provided at the bottom of the slider 301. A vertical groove is provided on the side of the column 1 near the slider 301. A partition 4 is engaged with the inner wall of the retaining sleeve 303. By sliding the slider 301 along the outer wall of the column 1, the deflection position of the rotating rod 302 is adjusted, controlling the horizontal extension length of the retaining sleeve 303 at one end of the rotating rod 302. By deflecting the retaining sleeve 303 along one end of the rotating rod 302, the connection angle between the partition 4 and the retaining sleeve 303 is adjusted. After one side of the partition 4 is connected, the other side of the partition 4 is connected to the connecting mechanism 3 on another column 1. The rotating rod 302 is pressed down synchronously along the vertical groove to adjust the vertical height of the retaining sleeve 303, reducing the need for adjustment of the overall position of the partition 4 and facilitating the installation of the partition by the user.

[0024] The partition 4 includes a clamping rod 403, one end of which is connected to a clamping sleeve 303. A rectangular frame 401 is provided on one side of the clamping rod 403, and a protective net 402 is provided on one side of the rectangular frame 401. An anti-theft sleeve 4031 and a fastening nut 4032 are sequentially provided at the bottom of the clamping rod 403. The anti-theft sleeve 4031 is sleeved with the clamping rod 403, and the fastening nut 4032 is connected to the inner wall of the anti-theft sleeve 4031. One end of the clamping rod 403 is engaged with the inner wall of the sleeve 303. The sleeve 303 horizontally deflects the partition 4, allowing the other side of the partition 4 to quickly connect with the column 1. After the clamping rod 403 and the sleeve 303 are engaged, the positions of the clamping rod 403 and the sleeve 303 are fixed by the anti-theft sleeve 4031 and the fastening nut 4032. The rectangular frame 401 increases the compressive strength of the partition 4, and the protective net 402 reduces the impact of crosswinds on the partition 4, thus improving the stability of the partition 4.

[0025] The clamping mechanism 5 includes a right-angle rotating plate 501. One side of the right-angle rotating plate 501 is connected to the rectangular frame 401. A sliding buckle 502 is provided on the top of the right-angle rotating plate 501. A vertical clamping plate 503 is hinged to the front of the sliding buckle 502. A counterweight is provided at the bottom of the vertical clamping plate 503. A horizontal clamping plate 506 is provided at the bottom of the right-angle rotating plate 501. The vertical clamping plate 503 is connected to one side of the warning sign 6. The horizontal clamping plate 506 is connected to the bottom of the warning sign 6. A gear 504 is provided on the back of the right-angle rotating plate 501. A transmission gear set 505 is provided at one end of the gear 504. Lower the warning sign 6 along one side of the right-angle rotating plate 501. First, the horizontal clamp 506 supports the bottom of the warning sign 6. The horizontal clamp 506 is subjected to downward pressure, causing the right-angle rotating plate 501 to deflect along the hinge point with the rectangular frame 401. This causes the vertical clamp 503 at the other end of the right-angle rotating plate 501 to clamp the side of the warning sign 6, thereby fixing the position of the warning sign 6. When the warning sign 6 is pulled upward, the horizontal clamp 506 releases the downward pressure, and at the same time, the clamp 503 on the side of the warning sign 6 is released, making it convenient for the user to assemble and disassemble the warning sign 6.

[0026] A central rotating rod is provided on the back of the right-angle rotating plate 501. The central rotating rod is connected to the rectangular frame 401 through a bearing. The transmission gear set 505 includes a gear ring 5051 and a stepped gear 5052. One side of the gear ring 5051 is connected to the back of the right-angle rotating plate 501. The center point of the gear ring 5051 coincides with the center point of the central rotating rod. The stepped gear 5052 is connected to the back of the right-angle rotating plate 501. The stepped gear 5052 includes a small-diameter gear and a large-diameter gear. One side of the small-diameter gear meshes with the gear ring 5051, and one side of the large-diameter gear meshes with the rack 504. While the warning sign 6 is placed on the horizontal clamping plate 506, the right-angle rotating plate 501 deflects around the central rotating rod. The right-angle rotating plate 501 simultaneously drives the gear ring 5051 to rotate, causing the gear ring 5051 to drive the meshing stepped gear 5052 to rotate. Through the differential transmission between the small-diameter gear and the large-diameter gear of the stepped gear 5052, the stepped gear 5052 quickly drives the rack 504 to slide along one side of the right-angle rotating plate 501. The rack 504 simultaneously drives the vertical clamping plate 503 on the sliding buckle 502 to move quickly, causing the vertical clamping plate 503 to move downward along one side of the right-angle rotating plate 501. This allows the vertical clamping plate 503 to quickly clamp the side of the warning sign 6, facilitating the placement of warning signs 6 of various sizes and improving the applicability of the clamping mechanism 5.

[0027] Working principle of the invention: When installing the column 1, holes are drilled at corresponding positions on the road surface through the through holes opened on the upper surface of the support base plate 202. Then, the position of the support base plate 202 is fixed by the expansion bolts 203, and the position of the connecting sleeve 201 is also fixed. The bottom end of the column 1 is inserted into the inner wall of the connecting sleeve 201. At the same time as the column 1 is inserted into the connecting sleeve 201, the vertical rack at the bottom end of the column 1 meshes with the transmission gear 206. The lowering of the column 1 drives the transmission gear 206 to rotate. The transmission gear 206 pushes the support clip 207 to move through the horizontal rack at the bottom. The support clip 207 extends outwards along the upper surface of the support base plate 202, increasing the support area between the support base plate 202 and the ground, improving the stability of the column 1. As the support clip 207 extends, it protects the top of the expansion bolts 203, reducing the impact on the expansion bolts 203 in subsequent operations. After the column 1 is fitted onto the inner wall of the connecting sleeve 201, the threaded retaining ring 204 is rotated along the outer wall of the connecting sleeve 201. The threaded retaining ring 204 drives the wedge-shaped retaining block 205 to move downwards, causing the wedge-shaped retaining block 205 to push the transmission gear 206 to move along the strip groove. One side of the transmission gear 206 disengages from the bottom end of the column 1. Then, the support retaining strip 207 slides along the upper surface of the support base plate 202, adjusting the distance between the support retaining strip 207 and the column 1, bringing the support retaining strip 207 closer to one side of the column 1. The end moves, causing the support clip 207 to fit against the bottom end of the column. Then, the threaded snap ring 204 is rotated to move the wedge-shaped clip 205 upward, causing the transmission gear 206 to re-engage with the column 1. At this time, when the column 1 is pulled up, the vertical rack at the bottom end of the column 1 drives the transmission gear 206 to rotate. The transmission gear 206 drives the support clip 207 to press against the bottom end of the column 1 through the horizontal rack, so that the support clip 207 clamps and fixes the bottom end of the column 1, restricting the vertical sway of the column 1 and improving the stability of the column 1. After the two adjacent columns 1 are successfully installed, slide the slider 301 along the outer wall of the column 1 to adjust the deflection position of the rotating rod 302, control the horizontal extension length of the hinged sleeve 303 at one end of the rotating rod 302, deflect the sleeve 303 along one end of the rotating rod 302, adjust the connection angle between the clamp rod 403 and the sleeve 303 on the partition 4, connect one side of the partition 4 to the column 1 through the sleeve 303, deflect the partition 4 through the sleeve 303 and the clamp rod 403, press down the rotating rod 302 synchronously along the vertical slide groove on the column 1, adjust the vertical height of the sleeve 303 to reduce the adjustment of the overall position of the partition 4, connect the other side of the partition 4 to another adjacent column 1, fix the position of the clamp rod 403 and the sleeve 303 through the anti-theft sleeve 4031 and the fastening nut 4032, and fix the position of the partition 4. When placing the warning sign 6, lower the warning sign 6 along one side of the right-angle rotating plate 501. First, the horizontal clamp 506 supports the bottom of the warning sign 6. The horizontal clamp 506 is subjected to downward pressure, which causes the right-angle rotating plate 501 to deflect along the center rod of the hinge point with the rectangular frame 401. This causes the vertical clamp 503 at the other end of the right-angle rotating plate 501 to clamp the side of the warning sign 6, thereby fixing the position of the warning sign 6. When the warning sign 6 is pulled upward, the horizontal clamp 506 releases the downward pressure and releases the clamp of the vertical clamp 503 on the side of the warning sign 6, making it convenient for the user to assemble and disassemble the warning sign 6. While the warning sign 6 is placed on the horizontal clamping plate 506, the right-angle rotating plate 501 deflects around the central rotating rod. The right-angle rotating plate 501 simultaneously drives the gear ring 5051 to rotate, which in turn drives the meshing stepped gear 5052 to rotate. Through the differential transmission between the small-diameter gear and the large-diameter gear of the stepped gear 5052, the stepped gear 5052 quickly drives the rack 504 to slide along one side of the right-angle rotating plate 501. The rack 504 simultaneously drives the vertical clamping plate 503 on the sliding buckle 502 to move quickly, causing the vertical clamping plate 503 to move downward along one side of the right-angle rotating plate 501. This allows the vertical clamping plate 503 to quickly clamp the side of the warning sign 6, making it convenient for users to place warning signs 6 of various sizes. When the partition 4 is blown by the crosswind, the partition 4 drives the column 1 to sway through the connecting mechanism 3. The column 1 sways and deflects along the inner wall of the connecting sleeve 201, causing the vertical rack at the bottom of the column 1 to move synchronously. The vertical rack at the bottom of the column 1 in the tilt direction drives the transmission gear 206 at the bottom to rotate, causing the transmission gear 206 to further push the support clip 207 to extend, increasing the contact area between the bottom of the column 1 in the tilt direction and the ground, and ensuring the stability of the column 1. When disassembling the column 1, rotate and remove the anti-theft sleeve and fastening nut at the bottom of the clamp 403. Then press down on the clamp 303 to release the clamp 303 from the clamp 403.
