[0018] A method for using a safety hoisting device for high-altitude pipeline installation comprises the following steps:

[0019] Step 1: When hoisting the glass and plates, place the glass and plates inside the placement slot for temporary limit, then start the double-headed electric push rod to drive the front and rear movable guide rails to move to the opposite side, and drive the connecting block and the movable limit block to move inside the placement slot through the movable guide rail, so that the movable limit block contacts the bottom of the glass and plate and squeezes and fixes them. When the movable limit block contacts the outside of the glass and plate, it contacts the rubber layer and squeezes the pressure controller. The pressure value is fed back to the external remote control center through the squeezing force, telling the staff that the pressure can be fixed during the limit extrusion, avoiding insufficient pressure during the limit fixation, resulting in a loose fixation. When the movable sleeve moves, the movable sleeve is limited and blocked by the stopper. When the movable limit block and the connecting block continue to move, the movable connecting rod is driven to slide inside the movable sleeve and the reset spring is stretched. Later, the reset spring is stretched and reset. When the hoisted glass and plate are unloaded, the movable limit block is driven to move and reset by the movable sleeve and the movable connecting rod. When the movable guide rail moves, the compressed air bag is squeezed. Later, the gas inside the compressed air bag is transported to the inside of the supporting air bag, so that the supporting air bag expands and contacts and fixes the bottom ends of the glass and plate.

[0020] Step 2: When the cable is being hoisted and wired, one end of the cable is passed through the inside of the triangular limiting opening, and one end of the cable is pulled through the inside of the triangular limiting opening so that one end of the cable contacts the top of the limiting blocking block, and the limiting hook head on the outside of the circular plate is squeezed into contact with the insulating layer outside the cable. The movable installation frame is moved toward the upper end of the inner cavity of the movable recess by the circular plate, and the compression spring is squeezed. The reaction force generated by the compression spring improves the tightness and fit between the limiting hook head and the outside of the cable. When the movable limiting block moves, it drives the movable installation frame, the circular plate and the limiting hook head to move, and drives the fixed cable to move, thereby reducing the distance between the movable limiting block and the limiting blocking block, which will further squeeze and fix one end of the cable.

[0021] Step 3: During the process of moving and hoisting, if tilt occurs during the hoisting process, the mounting ball will be used as the axis to ensure that the movable lever and the fixed block will not tilt. If it is subjected to squeezing force later, the fixed spring will be squeezed, and the squeezed fixed spring will drive the offset movable lever and the fixed block to reset. When the tilt is too large, the connecting guide ring will contact the guide piece installed on the outside of the contact ball, and the limit electromagnetic block will be triggered to disconnect the circuit of the limit electromagnetic block, and the alarm of the control center will be started to adjust the alarm. If the tilt is too large, the squeezing force on the contact ball will be greater, causing the contact ball to deform, and the deformed contact ball will contact the trigger switch, and further alarm prompts will be issued. The adjusting staff does not know the degree of tilt. When the tilt is too large, the pulling rope will be driven to move, and the moving round block will be driven to slide inside the mounting cylinder by the pulling rope. When the moving round block moves, the limit spring will be stretched, causing the movable guide ring to contact the fixed guide ring, and triggering the fixed electromagnetic block to disconnect the circuit of the fixed electromagnetic block;

[0022] Step 4: When the circuit of the fixed electromagnetic block is disconnected, the fixed electromagnetic block will lose its magnetism, and the moving block will lose its restraining force. The moving block will be driven upward by the tensile spring in the stretched state, and the movable mounting rod will be driven upward by the movement of the moving block. The movable mounting rod will be driven upward to move the moving bar upward. When the moving bar moves upward, the moving ball will be driven to roll on the outside of the glass and the plate, thereby increasing the flexibility of the moving bar during movement and reducing the friction of the moving bar during movement. When the glass and the plate are tilted during the hoisting process, the fixing range of the bottom fixed end of the glass and the plate is increased. When the circuit of the limit electromagnetic block is disconnected, the limit electromagnetic block loses its magnetism, and the moving slider loses its restraining force. The elastic rope is pulled in the state to drive the movable slider to move downward, and the downward movement of the movable slider drives the movable arch rod to move downward, and drives the circular airbag and the connecting hose to move, and the circular airbag and the connecting hose are opened, and the circular airbag and the connecting hose are covered on the outside of the glass and the plate, and the squeezing airbag is squeezed by moving the movable slider downward. When the squeezing airbag is squeezed, the air in the inner cavity of the squeezing airbag is respectively transported to the inside of the annular airbag, the connecting hose and the circular airbag through the air holes, so that the annular airbag and the circular airbag expand, and the annular airbag and the circular airbag are respectively in contact and squeezed with both sides of the hoisted glass and plate, and the glass and plate being hoisted are fixed when tilted, thereby increasing the protection capability of the glass and plate during the hoisting process.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention activates the adsorption limit mechanism and the bottom limit mechanism during hoisting, and activates the abnormal reinforcement mechanism through the bottom limit mechanism. During the process of moving and hoisting the glass and the plate, they are fixed in a dual manner, thereby increasing the firmness of the glass and the plate during hoisting, and can also fix glass and plates of different sizes. When moving and unloading, it is only necessary to move the fixed end and separate it from the outside of the glass and the plate, so that the glass and the plate lose the restraint force and can be moved and unloaded. This avoids the inability to fix glass and plates of different sizes during the process of moving and hoisting, and the unloading is not fast enough, resulting in cumbersome operation and reduced overall efficiency. In addition, the present invention can also perform fixed and wired operations on cables, and can fix and pull multiple cables at the same time according to needs, and can fix and pull cables of cables of different sizes.

[0025] 2. When an accident occurs during the hoisting process, the present invention triggers the abnormality monitoring mechanism to start the mobile limiting mechanism through the abnormality monitoring mechanism. When the glass and the plate are tilted during the hoisting process, the fixing range of the bottom fixing end of the glass and the plate is increased, thereby improving the limiting ability of the bottom end of the glass and the plate, and improving the fixing ability of the glass and the plate in the event of an accident, and increasing the protection ability of the glass and the plate in the event of an accident, thereby avoiding the situation in which the fixing range of the glass and the plate does not change in the event of an accident, which will cause the fixing ability of the glass and the plate to be reduced, and thus the protection ability of the glass and the plate to be reduced;

[0026] 3. The present invention also activates the supporting and stabilizing mechanism through the abnormal monitoring mechanism, and fixes the glass and plates being hoisted when tilt occurs, thereby increasing the protection ability of the glass and plates during the hoisting process, and avoiding tilting during the hoisting process, causing the glass and plates to fall and break, and injuring pedestrians. Through soft extrusion and fixation, not only the glass and plates themselves can be protected, but also a buffering effect can be played. If tilt occurs during the hoisting process and contacts with external solid objects or solid surfaces, it will not contact and collide with the glass and plates and play a buffering role, thereby further protecting the glass and plates during the hoisting process, avoiding tilting during the hoisting process, causing the glass and plates to contact with external solid objects, resulting in the glass and plates being broken. The broken parts fall from high altitude, and through the influence of wind and air pressure, the range of scattering is wider, resulting in greater safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom end of each movable bar 801 is mounted with a movable mounting rod 804, and the bottom end of each movable mounting rod 804 is mounted with a movable block 805. The bottom end of the inner cavity of the movable slot 803 is mounted with a fixed electromagnetic block 806, and the bottom end of each movable block 805 is mounted with a magnetic block. A tension spring 802 is mounted on one side of the top of each movable block 805, and the top end of each tension spring 802 is connected to the top end of the inner cavity of the movable slot 803. The tension spring 802 is in a stretched state, and balls are movably mounted around the outside of the movable block 805.

[0051] The specific implementation is as follows: when the circuit of the fixed electromagnetic block 806 is disconnected, the fixed electromagnetic block 806 will lose its magnetism, and the movable block 805 will lose its restraining force. The tensile spring 802 in a stretched state will drive the movable block 805 to move upward, and the movable mounting rod 804 will be driven upward by the movement of the movable block 805. The upward movement of the movable mounting rod 804 will drive the movable bar 801 to move upward.

When the glass and plate are tilted during the lifting process, the fixing range of the fixed end of the bottom end of the glass and plate is increased.

[0052] The supporting and stabilizing mechanism 5 also includes a limiting electromagnetic block 502, a pulling elastic rope 505, an extruding airbag 506, a circular airbag 507, a connecting hose 508, and a movable arch rod 509. The bottom end of the limiting top plate 3 is provided with a movable arch rod 509. The limiting electromagnetic block 502 is installed at the top end of the inner cavity of the movable slide 504. A pulling elastic rope 505 is installed on the left side of the movable slider 503.

The inner cavities of the limiting top plate 3 are located at positions opposite to the connecting hoses 508 and the fixed riser 2, and air holes are opened at positions opposite to the annular airbags 501, and the air holes are connected to the bottom ends of the extrusion airbags 506.

[0053] The specific implementation is as follows: when the use circuit of the limit electromagnetic block 502 is disconnected, the limit electromagnetic block 502 loses its magnetism, and the movable slider 503 loses its restraining force. The movable slider 503 is driven downward by pulling the elastic rope 505 in a stretched state. The downward movement of the movable slider 503 drives the movable arch rod 509 to move downward, and drives the circular airbag 507 and the connecting hose 508 to move. The circular airbag 507 and the connecting hose 508 are opened, and the circular airbag 507 and the connecting hose 508 are covered on the outside of the glass and the plate. The squeezing airbag 506 is squeezed by the downward movement of the movable slider 503. When the squeezing airbag 506 is squeezed, The air in the inner cavity of the extrusion airbag 506 is transported to the inside of the annular airbag 501, the connecting hose 508 and the circular airbag 507 through the air holes, so that the annular airbag 501 and the circular airbag 507 expand. The annular airbag 501 and the circular airbag 507 are respectively in contact and squeezed with the two sides of the hoisted glass and plate, and the hoisted glass and plate are fixed when tilted, thereby increasing the protection capability of the glass and plate during the hoisting process, and avoiding tilting during the hoisting process, causing the glass and plate to fall and break, and injuring pedestrians. Through soft extrusion and fixation, not only the glass and plate themselves can be protected, but also a buffering effect can be played.

[0054] The abnormality monitoring mechanism 7 also includes a fixed spring 704, a fixed block 705, a mounting ball 706, a movable lever 707, a trigger switch 708, a contact ball 709, a mounting cylinder 710, a movable block 711, a limit spring 712, a movable guide ring 713, a fixed guide ring 714 and a pulling rope 715. The mounting ball 706 is movably mounted in the inner cavity of the mounting sleeve 703, and a movable lever 707 is mounted in the middle of the inner cavity of the mounting ball 706. The bottom end of the movable lever 707 is mounted with a fixed block 705, and the top of the fixed block 705 is mounted with a fixed spring 704. The top of the fixed spring 704 is connected to the bottom end of the mounting sleeve 703. A number of contact balls 709 are mounted around the top of the movable lever 707. The contact balls 709 are made of rubber material.

[0055] The specific implementation method is as follows: during the process of mobile hoisting, if tilt occurs during the hoisting process, the mounting ball 706 will be used as the axis to ensure that the movable lever 707 and the fixed block 705 will not tilt. If they are subjected to extrusion force later, the fixed spring 704 will be squeezed, and the extruded fixed spring 704 will drive the offset movable lever 707 and the fixed block 705 to reset. When the tilt is too large, the connecting guide ring 702 will contact the guide piece installed on the outside of the contact ball 709, and trigger the limit electromagnetic block 502 to disconnect the circuit of the limit electromagnetic block 502, and start the alarm of the control center to sound the alarm. If the tilting force is too great, the squeezing force on the contact ball 709 will be greater, causing the contact ball 709 to deform, and the deformed contact ball 709 will contact the trigger switch 708, and further alarm prompts. The adjusting staff does not know the degree of tilt. When the degree of tilt is too great, it will drive the pull rope 715 to move, and the pull rope 715 will drive the moving ball 711 to slide inside the mounting tube 710. When the moving ball 711 moves, it drives the limit spring 712 to stretch, so that the movable guide ring 713 and the fixed guide ring 714 are in contact, and trigger the fixed electromagnetic block 806 to disconnect the circuit of the fixed electromagnetic block 806.

[0056] A number of round balls are movably installed around the outside of the movable circular block 711, a sliding hole is provided in the middle of the bottom end of the installation cylinder 710, a number of fixed rings 10 are equidistantly installed on the top of the fixed vertical plate 2, the fixing spring 704 and the limit spring 712 are made of spring steel, a triangular limiting opening 11 is provided at the bottom end of the movable limit block 401, and a limited blocking block 12 is installed on one side of the movable limit block 401 at the bottom end of the inner cavity of the placement slot 402. The limiting blocking blocks 12 are all V-shaped structures, and movable recesses 15 are provided at the upper ends of both sides of the inner cavity of the triangular limiting opening 11. Compression springs 16 are installed at the top of the inner cavity of the movable recess 15, and a movable installation frame 14 is installed at the bottom end of the compression spring 16. A circular plate 13 is installed inside the movable installation frame 14 through a ratchet wheel, and a number of limiting hooks 17 are equidistantly installed around the outside of the circular plate 13;

[0057] The specific implementation is as follows: when the moving ball 711 moves, it drives the ball to rotate through the rotation of the ball, thereby increasing the flexibility of the moving ball 711 during the movement process, reducing the friction of the moving ball 711 during the movement process, and increasing the elasticity and life of the fixed spring 704 and the limit spring 712 during use through the spring steel material. When the cable is hoisted and wired, one end of the cable is passed through the inside of the triangular limit opening 11, and one end of the cable is pulled through the inside of the triangular limit opening 11, so that one end of the cable contacts the top of the limit blocking block 12, and the limit on the outside of the circular plate 13 is The hook head 17 is in squeeze contact with the insulating layer on the outside of the cable, and the movable mounting frame 14 is moved toward the upper end of the inner cavity of the movable recess 15 through the circular plate 13, and the compression spring 16 is squeezed. The reaction force generated by the compression spring 16 improves the tightness and fit between the limit hook head 17 and the outside of the cable. When the movable limit block 401 moves, it drives the movable mounting frame 14, the circular plate 13 and the limit hook head 17 to move, and drives the fixed cable to move, thereby reducing the distance between the movable limit block 401 and the limit blocking block 12, and further squeezing and fixing one end of the cable. Example

[0058] A method for using a safety hoisting device for high-altitude pipeline installation comprises the following steps:

[0059] Step 1: When hoisting the glass and the plate, place the glass and the plate inside the placement slot 402 for temporary limit, then start the double-headed electric push rod 403 to drive the front and rear movable guide rails 405 to move to the opposite side, and drive the connecting block 411 and the movable limit block 401 to move inside the placement slot 402 through the movable guide rail 405, so that the movable limit block 401 contacts the bottom end of the glass and the plate and squeezes and fixes it, and when the movable limit block 401 contacts the outside of the glass and the plate, it contacts the rubber layer 409 and squeezes the pressure controller 410, and the pressure value is fed back to the external remote control center through the squeezing force, telling the staff that the pressure can be fixed during the limit squeezing, so as to avoid insufficient pressure during the limit fixation, resulting in insufficient firmness of the fixation, and when the connecting block 411 moves When the movable sleeve 412 is moved, the movable connecting rod 413 and the movable sleeve 412 are driven to move. When the movable sleeve 412 moves, the movable sleeve 412 is limited and blocked by the stopper. When the movable limiting block 401 and the connecting block 411 continue to move, the movable connecting rod 413 is driven to slide inside the movable sleeve 412 and stretch the return spring 408. Later, the return spring 408 is reset after stretching. When the glass and plate are unloaded after hoisting, the movable limiting block 401 is driven to move and reset by the movable sleeve 412 and the movable connecting rod 413. When the movable guide rail 405 moves, the compressed air bag 901 is squeezed. Later, the gas inside the compressed air bag 901 is transported to the inside of the supporting air bag 903, so that the supporting air bag 903 expands and contacts and fixes the bottom ends of the glass and plate.

[0060] Step 2: When the cable is being hoisted and wired, one end of the cable is passed through the inside of the triangular limiting opening 11, and one end of the cable is pulled through the inside of the triangular limiting opening 11, so that one end of the cable contacts the top of the limiting blocking block 12, and the limiting hook head 17 outside the circular plate 13 is squeezed and contacted with the insulating layer outside the cable, and the movable installation frame 14 is moved toward the upper end of the inner cavity of the movable recess 15 through the circular plate 13, and the compression spring 16 is squeezed. The reaction force generated by the compression spring 16 improves the fastening and fit between the limiting hook head 17 and the outside of the cable. When the movable limiting block 401 moves, it drives the movable installation frame 14, the circular plate 13 and the limiting hook head 17 to move, and drives the fixed cable to move, reducing the distance between the movable limiting block 401 and the limiting blocking block 12, which will further squeeze and fix one end of the cable;

[0061] Step 3: During the process of mobile hoisting, if tilt occurs during the hoisting process, the mounting ball 706 will be used as the axis to ensure that the movable lever 707 and the fixed block 705 will not tilt. If they are subjected to extrusion force later, the fixed spring 704 will be squeezed. Later, the extruded fixed spring 704 will drive the offset movable lever 707 and the fixed block 705 to reset. When the tilt is too large, the connecting guide ring 702 will contact the guide piece installed outside the contact ball 709, and trigger the limit electromagnetic block 502 to disconnect the circuit of the limit electromagnetic block 502, and start the alarm of the control center to adjust the alarm. If the tilting force is too great, the squeezing force on the contact ball 709 will be greater, causing the contact ball 709 to deform. The deformed contact ball 709 will then contact the trigger switch 708, and further alarm prompts will be given. The adjustment staff does not know the degree of tilt. When the degree of tilt is too great, the pull rope 715 will be driven to move, and the pull rope 715 will drive the movable round block 711 to slide inside the installation cylinder 710. When the movable round block 711 moves, the limit spring 712 will be stretched, causing the movable guide ring 713 to contact the fixed guide ring 714, and triggering the fixed electromagnetic block 806 to disconnect the circuit of the fixed electromagnetic block 806.

[0062] Step 4: When the circuit of the fixed electromagnetic block 806 is disconnected, the fixed electromagnetic block 806 will lose its magnetism, and the moving block 805 will lose its restraining force. The moving block 805 will be driven to move upward by the tension spring 802 in the stretched state, and the movable mounting rod 804 will be driven to move upward by the movement of the moving block 805. The upward movement of the movable mounting rod 804 will drive the moving bar 801 to move upward. When the moving bar 801 moves upward, it drives the moving ball 807 to roll on the outside of the glass and the plate, thereby increasing the flexibility of the moving bar 801 during the movement process and reducing the friction of the moving bar 801 during the movement process. When the glass and the plate are tilted during the hoisting process, the fixing range of the fixed end of the bottom end of the glass and the plate is increased. When the use circuit of the limit electromagnetic block 502 is disconnected, the limit electromagnetic block 502 loses its magnetism, and the moving slider 503 loses its restraining force, and the elastic rope is pulled in a stretched state. 505 drives the movable slider 503 to move downward, and the downward movement of the movable slider 503 drives the movable arch rod 509 to move downward, and drives the circular airbag 507 and the connecting hose 508 to move, and the circular airbag 507 and the connecting hose 508 are opened, and the circular airbag 507 and the connecting hose 508 are covered on the outside of the glass and the plate, and the squeezing airbag 506 is squeezed by the downward movement of the movable slider 503. When the squeezing airbag 506 is squeezed, the air in the inner cavity of the squeezing airbag 506 is respectively transported to the inside of the annular airbag 501, the connecting hose 508 and the circular airbag 507 through the air hole, so that the annular airbag 501 and the circular airbag 507 expand, and the annular airbag 501 and the circular airbag 507 are respectively in contact and squeezed with the two sides of the hoisted glass and plate, and the hoisted glass and plate are fixed when tilted, thereby increasing the protection capability of the glass and plate during the hoisting process.

6. A method for using a safety hoisting device for high-altitude pipeline installation, characterized in that: The method for using the safety hoisting device is applicable to the safety hoisting device for high-altitude pipeline installation according to claim 5, comprising the following steps: Step 1: When hoisting the glass and the plate, place the glass and the plate inside the placement slot (402) for temporary positioning, then start the double-headed electric push rod (403) to drive the front and rear movable guide rails (405) to move to the opposite side, and drive the connecting block (411) and the movable limit block (401) to move inside the placement slot (402) through the movable guide rail (405), so that the movable limit block (401) contacts the bottom of the glass and the plate and squeezes and fixes it, and when the movable limit block (401) contacts the outside of the glass and the plate, it contacts the rubber layer (409) and squeezes the pressure controller (410), and the pressure value is fed back to the external remote control center through the squeezing force, telling the staff that the pressure can be fixed when the limit is squeezed, so as to avoid insufficient pressure when the limit is fixed, resulting in insufficient firmness of the fixation. When the connecting block (411) moves, it will drive the movable limit block (401) to move. The movable connecting rod (413) and the movable sleeve (412) move. When the movable sleeve (412) moves, the movable sleeve (412) is limited and blocked by the stopper. When the movable limiting block (401) and the connecting block (411) continue to move, the movable connecting rod (413) is driven to slide inside the movable sleeve (412) and stretch the return spring (408). Later, the return spring (408) is stretched and reset. When the hoisted glass and plate are unloaded, the movable limiting block (401) is driven to move and reset by the movable sleeve (412) and the movable connecting rod (413). When the movable guide rail (405) moves, the compressed air bag (901) is squeezed. Later, the gas inside the compressed air bag (901) is transported to the inside of the support air bag (903), so that the support air bag (903) expands and contacts and fixes the bottom of the glass and plate. Step 2: When the cable is being hoisted and wired, one end of the cable is passed through the inside of the triangular limiting opening (11), and one end of the cable is pulled through the inside of the triangular limiting opening (11) so that one end of the cable contacts the top of the limiting block (12), and the limiting hook (17) outside the circular plate (13) is squeezed into contact with the insulation layer outside the cable. The movable installation frame (14) is moved toward the upper end of the inner cavity of the movable recess (15) through the circular plate (13), and the compression spring (16) is squeezed. The reaction force generated by the compression spring (16) improves the tightness and fit between the limiting hook (17) and the outside of the cable. When the movable limiting block (401) moves, it drives the movable installation frame (14), the circular plate (13) and the limiting hook (17) to move, and drives the fixed cable to move, thereby reducing the distance between the movable limiting block (401) and the limiting block (12), and further squeezing and fixing one end of the cable. Step 3: During the process of moving and hoisting, if tilting occurs during the hoisting process, the mounting ball (706) will be used as the axis to ensure that the movable lever (707) and the fixed block (705) will not tilt. If they are squeezed later, the fixed spring (704) will be squeezed. Later, the squeezed fixed spring (704) will drive the offset movable lever (707) and the fixed block (705) to reset. When the tilt is too large, the connecting guide ring (702) will contact the guide piece installed outside the contact ball (709), and trigger the limit electromagnetic block (502) to disconnect the circuit of the limit electromagnetic block (502), and start the alarm of the control center to adjust the alarm. If the tilt is too large, the connecting guide ring (702) will contact the guide piece installed outside the contact ball (709), and trigger the limit electromagnetic block (502) to disconnect the circuit of the limit electromagnetic block (502), and start the alarm of the control center to adjust the alarm. If the tilting force is too great, the squeezing force on the contact ball (709) will be greater, causing the contact ball (709) to deform, and the deformed contact ball (709) will contact the trigger switch (708), and further alarm prompts. The adjustment staff does not know the degree of tilting. When the degree of tilting is too great, the pull rope (715) will be driven to move, and the pull rope (715) will drive the movable round block (711) to slide inside the installation cylinder (710). When the movable round block (711) moves, the limit spring (712) will be stretched, so that the movable guide ring (713) and the fixed guide ring (714) are in contact, and the fixed electromagnetic block (806) will be triggered to disconnect the circuit of the fixed electromagnetic block (806); Step 4: When the circuit of the fixed electromagnetic block (806) is disconnected, the fixed electromagnetic block (806) loses its magnetism, and the moving block (805) loses its restraining force. The moving block (805) is driven to move upward by the tension spring (802) in a stretched state, and the movable mounting rod (804) is driven to move upward by the movement of the moving block (805). The upward movement of the movable mounting rod (804) drives the moving bar (801) to move upward. When the moving bar (801) moves upward, the moving ball (807) is driven to roll on the outside of the glass and the plate, increasing the flexibility of the moving bar (801) during the movement process and reducing the friction of the moving bar (801) during the movement process. When the glass and the plate are tilted during the hoisting process, the fixing range of the bottom fixed end of the glass and the plate is increased. When the use circuit of the limit electromagnetic block (502) is disconnected, the limit electromagnetic block (502) loses its magnetism, and the moving slider (503) loses its restraining force. Pulling the elastic rope (505) drives the movable slider (503) to move downward, and the movable arch rod (509) is driven downward by the downward movement of the movable slider (503), and the circular airbag (507) and the connecting hose (508) are driven to move. The circular airbag (507) and the connecting hose (508) are opened, and the circular airbag (507) and the connecting hose (508) are covered on the outside of the glass and the plate. The movable slider (503) is moved downward to squeeze the airbag (506). When the squeezing airbag (506) is squeezed, the air in the inner cavity of the squeezing airbag (506) is transported to the inside of the annular airbag (501), the connecting hose (508) and the circular airbag (507) through the air holes, so that the annular airbag (501) and the circular airbag (507) expand. Then, the annular airbag (501) and the circular airbag (507) respectively contact and squeeze the two sides of the suspended glass and plate, and fix the suspended glass and plate when tilting occurs.
