Description

Technical Field

[0001] This utility model relates to the field of track technology, and in particular to a movable and fixed component. Background Technology

[0002] The rapid development of the railway industry has resulted in a large amount of idle or scrapped railway resources. Taking my country as an example, as of 2024, the operating mileage of railways had reached 162,000 kilometers. With the acceleration of high-speed rail construction and the improvement of track quality requirements, the number of scrapped railway tracks continues to increase. Currently, many scrapped tracks are disposed of by on-site burial due to high recycling costs, high technical barriers (requiring specialized smelting equipment for purification), and low economic benefits, resulting in resource waste and land occupation problems. In addition to remote sections, there are also many short-term or long-term idle tracks in railway stations, operation and maintenance centers, technical centers, and industrial sites such as mines and ports. If these scrapped tracks and idle railway spaces are not used rationally, it will lead to resource waste.

[0003] In the field of energy utilization, photovoltaic power generation, as an important source of clean energy, has attracted much attention for its development and utilization. Laying photovoltaic panels on railway tracks to effectively combine railway resources with photovoltaic power generation is a good solution, as it can make full use of idle railway resources and increase the supply of clean energy. However, existing technologies lack effective solutions for how to fix photovoltaic power generation devices on the tracks and enable them to be moved flexibly in extreme weather conditions such as hurricanes and hail.

[0004] In the field of logistics and warehousing, abandoned tracks can be used to build temporary or permanent cargo transportation and storage systems, which can reduce site construction costs. However, existing technologies lack effective solutions for how to stably fix cargo racks, transfer devices, etc., on the tracks and prevent displacement due to vibration or external collisions.

[0005] When securing equipment to abandoned railway tracks, the unique cross-sectional shape of the tracks (often I-beams) makes it difficult for conventional locking devices to achieve a stable fit, leading to equipment wobbling or even detachment during long-term use. Furthermore, in many scenarios, the equipment needs to be moved to a suitable position on the track before being secured, and existing devices often struggle to balance ease of movement with stability.

In fact, those skilled in the art will recognize that modifications and variations can be made to the present invention without departing from the scope or spirit of the invention. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. Therefore, it is desirable that the present invention encompass such modifications and variations that fall within the scope of the appended claims and their equivalents.

[0056] It should be noted that, in order to clearly show the structural relationship of the internal key components of this utility model, some pipelines, lines, support brackets and other components of the actual product are omitted in the drawings. However, the specific design schemes of these omitted components are all easily implemented by those skilled in the art based on the technical solutions currently provided by this utility model and conventional design.

They are used only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected," "linked," and "set up" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; they can refer to a direct connection or an indirect connection through intermediate components. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0058] Example 1:

[0059] like Figures 1-26 As shown, a movable fixing assembly includes a roller 131, a bracket 14, and a fixing member 16.

[0060] Roller 131 is adapted to track 2;

[0061] The bracket 14 includes a left plate 141, a connecting plate 142 and a right plate 143 connected in sequence. The left plate 141 and the right plate 143 are respectively connected to the two ends of the axle of the roller 131.

[0062] The fastener 16 includes a first claw 161, a second claw 162, a claw frame 163, and an adjusting bolt 164;

[0063] The left wall of the gripper frame 163 is rotatably connected to the left plate 141 via a left pivot 1631, and the right wall of the gripper frame 163 is rotatably connected to the right plate 143 via a right pivot 1632. A gripper hinge shaft 1633 is connected between the front and rear walls of the gripper frame 163. The first gripper 161 and the second gripper 162 are hinged to each other via the gripper hinge shaft 1633 and pass through the inside of the gripper frame 163. The first gripper 161 and the second gripper 162 clamp or release the track 2 via the adjusting bolt 164.

[0064] In practical implementation, the fixing component 16 adopts an adjustable gripper structure. The opening and closing action of the first gripper 161 and the second gripper 162 can be achieved through mechanical transmission. When the first gripper 161 and the second gripper 162 are closed, the clamping track 2 can lock the equipment fixed by the moving fixing component to the track 2 by the dual action of friction and mechanical engagement. The front wall, rear wall, left wall, and right wall of the gripper frame 163 can be designed to be detachably connected by bolts, allowing each wall to be disassembled individually, which facilitates the replacement or maintenance of components such as the first gripper 161 and the second gripper 162 inside the gripper frame 163.

[0065] The rotatable connection between the gripper frame 163 and the left plate 141 and right plate 143 allows the fixing member 16 to adapt to different positions and angles of the track 2, thereby improving the adaptability of the device. The clamping action of the first claw 161 and the second claw 162 can firmly fix the device on the track 2 and prevent the device from moving during operation.

[0066] Example 2:

[0067] Furthermore, the top of the first claw 161 is rotatably connected to an adjusting shaft 1611, and the top of the second claw 162 is rotatably connected to an adjusting shaft 1621. Both the adjusting shaft 1611 and the adjusting shaft 1621 are provided with through holes. The through hole of the adjusting shaft 1611 is a threaded hole. The adjusting bolt 164 passes through the through hole of the adjusting shaft 1621 and is threadedly connected to the through hole of the adjusting shaft 1611. The bolt head of the adjusting bolt 164 abuts against the outside of the adjusting shaft 1621.

[0068] In practice, when the adjusting bolt 164 is rotated, the maximum distance that can be formed between the adjusting shaft 1611 and the adjusting shaft 1621 changes because the adjusting bolt 164 is threadedly connected to the adjusting shaft 1611. When it is necessary for the first claw 161 and the second claw 162 to be clamped on the track 2, rotating the adjusting bolt 164 reduces the maximum distance that can be formed between the adjusting shaft 1611 and the adjusting shaft 1621, thereby causing the first claw 161 and the second claw 162 to rotate around the claw hinge shaft 1633, thus achieving the clamping or loosening of the first claw 161 and the second claw 162 on the track 2. When it is necessary to loosen the first claw 161 and the second claw 162 on the track 2, rotating the adjusting bolt 164 increases the maximum distance that can be formed between the adjusting shaft 1611 and the adjusting shaft 1621, and the first claw 161 and the second claw 162 will be released from the clamped state. The opening and closing of the first claw 161 and the second claw 162 can be controlled by adjusting the bolt 164, which facilitates quick switching between fixing and moving the device on the track 2. The claw frame 163 is rotatably connected to the left plate 141 and the right plate 143, allowing the fixing member 16 to adapt to different positions and angles on the track 2, thereby improving the adaptability of the device.

[0069] More specifically, the adjusting bolt 164 includes a threaded section and a smooth section. The threaded section engages with the threaded hole of the adjusting shaft 1611 to achieve axial displacement adjustment, while the smooth section passes through the through hole of the adjusting shaft 1621.

[0070] Example 3:

[0071] Furthermore, the right wall of the gripper frame 163 is provided with a right fixing inner hole 1637, and the right plate 143 is provided with a right fixing outer hole 1431.

[0072] When the right fixed inner hole 1637 and the right fixed outer hole 1431 are connected by a connector, the gripper frame 163 cannot rotate relative to the right plate 143 via the right rotating shaft 1632 to achieve the folding of the fixing member 16.

[0073] In practice, the right fixing inner hole 1637 and the right fixing outer hole 1431 are locked together by a connector, so that the gripper frame 163 is in a folded state (e.g., Figure 2 (As shown). After releasing the connecting piece, the gripper frame 163 can rotate around the left rotation axis 1631 and the right rotation axis 1632 to the working position (as shown). Figure 1 (As shown). More specifically, the right fixed inner hole 1637 can be a threaded hole, and the connecting parts can be bolts, quick-lock pins, or locking knobs with handles.

[0074] Example 4:

[0075] Furthermore, the right plate 143 is provided with a right adjustment hole 1432. By passing an adjustment tool through the right adjustment hole 1432, the adjustment bolt 164 can be adjusted to change the opening and closing degree of the first claw 161 and the second claw 162.

[0076] In practice, by setting the right adjustment hole 1432, the adjustment tool can pass through the right adjustment hole 1432 to rotate the adjustment bolt 164, so that the bracket 14 will not interfere with the adjustment tool and ensure the smooth adjustment process.

[0077] Example 5:

[0078] Furthermore, the top of the first claw 161 is rotatably connected to an adjusting shaft 1611, and the top of the second claw 162 is rotatably connected to an adjusting shaft 1621. Both the adjusting shaft 1611 and the adjusting shaft 1621 are provided with through holes. The through hole of the adjusting shaft 1621 is a threaded hole. The adjusting bolt 164 passes through the through hole of the adjusting shaft 1611 and is threadedly connected to the through hole of the adjusting shaft 1621. The bolt head of the adjusting bolt 164 abuts against the outside of the adjusting shaft 1611, so that the first claw 161 and the second claw 162 can be clamped or loosened on the track 2.

[0079] In practice, when the adjusting bolt 164 is rotated, the maximum distance that can be formed between the adjusting shaft 1611 and the adjusting shaft 1621 changes because the adjusting bolt 164 is threadedly connected to the adjusting shaft 1621. When it is necessary for the first claw 161 and the second claw 162 to be clamped on the track 2, rotating the adjusting bolt 164 reduces the maximum distance that can be formed between the adjusting shaft 1611 and the adjusting shaft 1621, thereby causing the first claw 161 and the second claw 162 to rotate around the claw hinge shaft 1633, thus achieving the clamping or loosening of the first claw 161 and the second claw 162 on the track 2. When it is necessary to loosen the first claw 161 and the second claw 162 on the track 2, rotating the adjusting bolt 164 increases the maximum distance that can be formed between the adjusting shaft 1611 and the adjusting shaft 1621, and the first claw 161 and the second claw 162 will release from the clamped state. The opening and closing of the first claw 161 and the second claw 162 can be controlled by adjusting the bolt 164, which facilitates the quick switching between fixing and moving the device on the track 2.

[0080] More specifically, the adjusting bolt 164 includes a threaded section and a smooth section. The threaded section engages with the threaded hole of the adjusting shaft 1621 to achieve axial displacement adjustment, while the smooth section passes through the through hole of the adjusting shaft 1611.

[0081] Example 6:

[0082] Furthermore, the left wall of the gripper frame 163 is provided with a left fixing inner hole 1636, and the left plate 141 is provided with a left fixing outer hole 1411; when the left fixing inner hole 1636 and the left fixing outer hole 1411 are connected by a connector, the gripper frame 163 cannot rotate relative to the left plate 141 via the left rotating shaft 1631, so as to realize the folding of the fixing member 16.

[0083] In practice, the left fixed inner hole 1636 and the left fixed outer hole 1411 are locked together by a connector, so that the gripper frame 163 is in a folded state. After the connector is released, the gripper frame 163 can rotate around the left pivot 1631 and the right pivot 1632 to the working position. More specifically, the left fixed inner hole 1636 can be a threaded hole, and the connector can be a bolt, a quick-lock pin, or a locking knob with a handle.

[0084] While locking the right fixed inner hole 1637 and the right fixed outer hole 1431 with the connector, the left fixed inner hole 1636 and the left fixed outer hole 1411 are also locked with the connector, which can restrict the rotation of the gripper frame 163 from both sides at the same time.

[0085] Example 7:

[0086] Furthermore, the left plate 141 is provided with a left adjustment hole 1412. By passing an adjustment tool through the left adjustment hole 1412, the adjustment bolt 164 can be adjusted to change the opening and closing degree of the first claw 161 and the second claw 162.

[0087] In practical implementation, by providing the left adjustment hole 1412, the adjustment tool can pass through the left adjustment hole 1412 to rotate the adjustment bolt 164, ensuring that the bracket 14 does not interfere with the adjustment tool and that the adjustment process is smooth. Only one adjustment hole is needed to facilitate the adjustment of the adjustment bolt 164. By providing two adjustment holes, the left adjustment hole 1412 and the right adjustment hole 1432, adjustment can be made from different directions, increasing the applicability of the movable fixing component.

[0088] Example 8:

[0089] Furthermore, the track 2 is an I-shaped track, which includes a rail head 21, a rail web 22, and a rail bottom 23 connected from top to bottom. The clamping parts of the first claw 161 and the second claw 162 are used to clamp the rail head 21.

[0090] In practice, given the special shape of the I-shaped track, clamping the rail head 21 makes it easier to achieve a stable fixation.

[0091] Example 9:

[0092] Furthermore, the clamping part of the first claw 161 includes claw segment 1612, claw segment 2 1613 and claw segment 3 1614 connected sequentially from top to bottom, and the clamping part of the second claw 162 includes claw segment 4 1622, claw segment 5 1623 and claw segment 6 1624 connected sequentially from top to bottom.

[0093] When the first claw 161 and the second claw 162 are clamped on the rail head 21, claw segment 1612 and claw segment 41622 abut against the upper oblique end of the rail head 21, claw segment 21613 and claw segment 51623 abut against the lower oblique end of the rail head 21, and claw segment 31614 and claw segment 61624 are located on the lower side of the rail head 21.

[0094] In practice, the first claw segment 1612, the second claw segment 1613, and the third claw segment 1614 of the first claw 161, together with the fourth claw segment 1622, the fifth claw segment 1623, and the sixth claw segment 1624 of the second claw 162, can form a ring-shaped fixation around the rail head 21, ensuring a stable clamping and preventing slippage, thus avoiding the equipment from falling off under vibration or storm conditions. Furthermore, the clamping process will not cause wear to the running surface of the rail 2 (i.e., the upper surface of the rail head 21), extending the service life of the rail 2.

[0095] Example 10:

[0096] Furthermore, the roller 131 and the fixing member 16 are connected to the target device 1 via the connecting plate 142.

[0097] The target device 1 can be various equipment or engineering structures such as photovoltaic panels, communication base stations, surveillance cameras, emergency lighting devices, logistics cargo boxes, track maintenance platforms, or temporary bridge sections. The moving parts 13 of the target device 1 can all be rollers 131 with brackets 14 and fixing parts 16, or they can be configured with a mixture of ordinary rollers, sliding blocks, or guide wheels.

[0098] Based on the above technical solutions, taking the target device 1 as a photovoltaic panel as an example, this utility model can quickly provide temporary power for railway construction sites, stations, technical centers, rail welding and maintenance points, and remote areas.

[0099] When the movable fixing component is fixed to the target device 1:

[0100] The target device 1 can be moved on the track 2 by the roller 131 and fixed on the track 2 by the fastener 16.

[0101] When the target device 1 is moved on track 2:

[0102] The target device 1 moves on the track 2 via the roller 131. At this time, the right fixed inner hole 1637 and the right fixed outer hole 1431 are connected by a connector so that the fixing member 16 is folded and fixed on the bracket 14 and does not contact the track 2.

[0103] When target device 1 is fixed on track 2:

[0104] Remove the connecting piece between the right fixed inner hole 1637 and the right fixed outer hole 1431, so that the gripper frame 163 can rotate freely through the left rotating shaft 1631 and the right rotating shaft 1632, thereby adjusting the fixing piece 16 to the clamping position corresponding to the track 2;

[0105] Adjust the adjusting bolt 164 using the adjusting tool to bring the first claw 161 and the second claw 162 toward the rail head 21 until claw segment 1 1612 and claw segment 4 1622 abut against the upper oblique end of the rail head 21, claw segment 2 1613 and claw segment 5 1623 abut against the lower oblique end of the rail head 21, and claw segment 3 1614 and claw segment 6 1624 are located on the lower side of the rail head 21.

[0106] Preferably, the fastener 16 is detachably connected to the limiting member 165;

[0107] The front wall of the gripper frame 163 is provided with a front limiting hole 1634, and the rear wall of the gripper frame 163 is provided with a rear limiting hole 1635. The limiting member 165 can pass through the front limiting hole 1634 and exit through the rear limiting hole 1635. The portion of the limiting member 165 located inside the gripper frame 163 can form a stop on the first claw 161 and / or the second claw 162 to limit the maximum opening degree of the first claw 161 and the second claw 162.

[0108] In practical implementation, although the clamping or loosening of the first claw 161 and the second claw 162 on the track 2 can be achieved by rotating the adjusting bolt 164, there are still some application scenarios where it is necessary to keep the first claw 161 and the second claw 162 clamped on the track 2 without disengaging, but also to maintain a certain amount of room for movement. In this case, the role of the limiting member 165 becomes particularly important. By setting the limiting member 165, it can form a stop on the first claw 161 and / or the second claw 162 (e.g., Figure 16 As shown in the diagram, even if the adjusting bolt 164 is adjusted further, the first claw 161 and the second claw 162 cannot open further, ensuring both stability and flexibility of the device on the track 2. This prevents accidental dislodgement while allowing necessary fine-tuning. Simultaneously, by removing the limiting component 165, the first claw 161 and the second claw 162 can be fully opened again, facilitating coarse adjustment, disassembly, or replacement of the device. The limiting component 165 can be a bolt, pin, shaft pin, elastic pin, etc., and can be adjusted according to actual needs.

[0109] Existing technologies for gripper designs rarely address their application in fixing and fine-tuning equipment on tracks, thus seldom include designs that limit the maximum opening of the grippers using detachable limiting components. This invention, by adding a limiting component 165, effectively solves the problem of excessive opening of the grippers during use, improving the stability and reliability of the fixation.

[0110] Preferably, the limiting member 165 includes a large diameter section 1651 and a small diameter section 1652;

[0111] The outer diameter of the large diameter section 1651 is larger than the inner diameter of the front limiting hole 1634. The small diameter section 1652 can pass through the front limiting hole 1634 and exit through the rear limiting hole 1635. A limiting bead 16521 is provided at the front of the small diameter section 1652. The limiting bead 16521 can extend and retract in the small diameter section 1652 with the help of external force. When the limiting bead 16521 extends, the outer diameter of the small diameter section 1652 at the limiting bead 16521 is larger than the inner diameter of the rear limiting hole 1635, so as to prevent the limiting member 165 from accidentally falling out of the rear limiting hole 1635.

[0112] In practical implementation, the limiting bead 16521 can be selected from existing components such as umbrella positioning pins, ball plungers, spring plungers, and elastic locking pins. The limiting bead 16521 protrudes under radial elastic force and is locked outside the rear limiting hole 1635, preventing the limiting member 165 from axially slipping and ensuring the limiting member 165 is securely locked. Simultaneously, the design of the limiting bead 16521 allows it to retract under external force, facilitating the quick disassembly and installation of the limiting member 165.

[0113] Preferably, the large-diameter section 1651 is provided with a first hole 16511 and a second hole 16512, and the small-diameter section 1652 is provided with a third hole 16522 and a fourth hole 16523;

[0114] The front end of the first hole 16511 is connected to the second hole 16512, the front end of the second hole 16512 is connected to the third hole 16522, the front part of the third hole 16522 is connected to the fourth hole 16523, the fourth hole 16523 is a variable diameter hole, and the minimum inner diameter of the fourth hole 16523 is smaller than the outer diameter of the limiting bead 16521.

[0115] A rotating seat 1653 is connected to the first hole 16511. The rotating seat 1653 is threadedly connected to the first hole 16511. A push rod 1654 is connected to the front end of the rotating seat 1653. The push rod 1654 passes through the first hole 16511 and extends through the second hole 16512 to the third hole 16522. The front part of the push rod 1654 is provided with a reduced diameter section 16541, a transition section 16542 and a main body section 16543 from front to back. The outer diameter of the reduced diameter section 16541 is smaller than the outer diameter of the main body section 16543. The outer diameter of the transition section 16542 transitions from the outer diameter of the reduced diameter section 16541 to the outer diameter of the main body section 16543.

[0116] By rotating the rotating seat 1653, the push rod 1654 can move back and forth within the third hole 16522, thereby realizing the extension and retraction control of the limiting bead 16521. When the bottom of the limiting bead 16521 contacts the reduced diameter section 16541, the top of the limiting bead 16521 is inside the fourth hole 16523. When the bottom of the limiting bead 16521 contacts the main body section 16543, the top of the limiting bead 16521 extends out of the fourth hole 16523.

[0117] In practical implementation, the outer circumference of the rotating seat 1653 can be fully threaded with the inner wall of the first hole 16511, or only partially threaded with the rest being smooth. For the smooth surface, a lubricating material can be applied to the inner wall of the first hole 16511 or a bushing can be added to reduce friction. The reduced diameter section 16541, transition section 16542, and main body section 16543 of the push rod 1654 move axially within the third hole 16522, controlling the extension and retraction of the limit bead 16521. One, two, or more fourth holes 16523 can be provided, with the number of corresponding limit beads 16521 increasing synchronously. The variable diameter hole of the fourth hole 16523 can be a tapered hole, an inner spherical hole, etc.

[0118] In specific work, such as Figures 17-26 As shown, the rotating seat 1653 rotates → the push rod 1654 moves axially → the reduced diameter section 16541 or the main body section 16543 acts on the limiting bead 16521 → the limiting bead 16521 retracts or extends.

[0119] Compared with the existing technology that uses components such as umbrella positioning pins, ball plungers, spring plungers, and elastic locking pins to achieve the extension and retraction of the limiting ball 16521, this design can control the extension and retraction more precisely and stably. Furthermore, when disassembling and assembling the limiting component 165, there is no frictional contact between the limiting ball 16521 and the hole wall of the rear limiting hole 1635, avoiding jamming and preventing damage to the extension and retraction structure and hole wall of the limiting ball 16521, thereby extending its service life.

[0120] Preferably, the rotating seat 1653 is provided with an insertion hole for inserting the rotating member 1655. When the rotating member 1655 is inserted into the insertion hole of the rotating seat 1653, the rotating seat 1653 can be rotated by rotating the rotating member 1655, thereby pushing the push rod 1654 to move back and forth in the third hole 16522.

[0121] In practical implementation, the rotating base 1653 can be designed to be difficult to rotate directly with fingers. For example, the rear end face of the rotating base 1653 can be flush with or located inside the large-diameter section 1651, making it difficult for fingers to rotate the rotating base 1653 directly. The rear end of the rotating base 1653 has an insertion hole corresponding to the shape of the rotating component 1655. The rotating component 1655 can be designed as rectangular, hexagonal, or other irregular shapes. The rotating component 1655 transmits torque, allowing the operator to apply force to rotate the rotating base 1653. Pulling out the rotating component 1655 interrupts the torque transmission path, making it difficult for the rotating base 1653 to rotate. This design reduces the risk of unauthorized personnel maliciously adjusting the limiting component 165, thereby improving the operational safety of the device and the anti-theft level of the facility.

[0122] When performing clamping adjustment, no limiting member 165 is inserted between the front limiting hole 1634 and the rear limiting hole 1635.

[0123] After clamping and adjustment, insert the limiting member 165 through the front limiting hole 1634 and out through the rear limiting hole 1635. Rotate the rotating member 1655 to drive the rotating seat 1653 to rotate, so that the push rod 1654 moves to the bottom of the main body section 16543 and contacts the bottom of the limiting bead 16521, causing the top of the limiting bead 16521 to extend out of the fourth hole 16523, preventing the limiting member 165 from accidentally falling out of the rear limiting hole 1635. Then pull out the rotating member 1655.

[0124] Preferably, the rotating component 1655 has a key structure, and the large-diameter section 1651 is provided with a lock cylinder structure 1656 that matches the key structure. The lock cylinder structure 1656 includes a spring 16561, a first tumbler 16562 and a second tumbler 16563. The lock cylinder structure 1656 is used to lock the rear of the rotating seat 1653, and the front of the rotating seat 1653 is threadedly connected to the front of the first hole 16511.

[0125] When the key structure is not inserted into the lock cylinder structure 1656, the first pin 16562 and the second pin 16563 are pushed out by the elastic force of the spring 16561, so that the rear of the rotating seat 1653 is locked, thereby preventing the rotating seat 1653 from rotating.

[0126] When the key mechanism is inserted into the lock cylinder structure 1656, the first pin 16562 and the second pin 16563 are pushed back by the key mechanism, thereby unlocking the rear of the rotating seat 1653 and allowing the rotating seat 1653 to rotate.

[0127] In practical implementation, when the rotating component 1655 is designed with a key structure, and a lock cylinder structure 1656 is installed inside the large-diameter section 1651, such as... Figures 22-26 As shown, in the key structure removed state ( Figure 22The first pin 16562 and the second pin 16563 extend outward under the action of the spring 16561 and are engaged in the internal groove of the rotating seat 1653, thus locking the rotating seat 1653; in the key structure insertion state ( Figure 23 , Figure 24 The key teeth push the second pin 16563, which in turn compresses the spring 16561 via the first pin 16562. This ensures that the junction of the first pin 16562 and the second pin 16563 is precisely located on the outer circumference of the rotating base 1653, allowing the rotating base 1653 to rotate freely and thus unlocking the device. The rotating component 1655 locks and unlocks the rotating base 1653, ensuring that the extension / retraction state of the limit bead 16521 can only be adjusted using the rotating component 1655 with a specific key structure. By designing a unique key structure for each limit component 165, the safety and professionalism of the operation are ensured, preventing unauthorized personnel from arbitrarily adjusting the limit bead 16521, thereby enhancing the safety protection of the equipment.
