Description

Technical Field

[0001] The present invention relates to the technical field of aluminum formwork systems, and particularly to an aluminum alloy formwork that is convenient for disassembly and assembly. Background Art

[0002] The aluminum alloy formwork system includes an aluminum formwork main body and various connecting fittings, among which the most commonly used are pin and wedge connectors.

[0003] During operation, generally, a vertical hammer is directly used to strike the wedge in the pin and wedge connector. After the connection is completed, all the formworks are reinforced by tie rods. However, during specific connection, the pin and wedge connector must be used to connect the topmost and bottommost parts of the formwork to ensure the stability of the formwork. At the top of the formwork main body, due to the obstruction of the end edge, when installing the pin and wedge connector, the wedge needs to be inserted into the pin from top to bottom. Therefore, generally, a certain gap needs to be reserved between a connection hole at the topmost part of the formwork main body and the end edge to provide space for the wedge to be inserted into the pin from top to bottom and for vertically hammering the upper end of the wedge. However, this method sacrifices the connection tightness at the topmost part of the formwork main body, resulting in a lower position setting of the connection hole at the uppermost layer, making it difficult to use the pin and wedge connector to connect the topmost part of the formwork main body, and causing the connection at the upper end of the formwork to be not tight.

[0004] If the pin and wedge connector is presented in an inclined posture, although it is convenient for operation, the vibration resistance of its wedge is weaker and it is easy to fall off from the pin. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides an aluminum alloy formwork that is convenient for disassembly and assembly, and solves the problem of poor connection tightness at the topmost part of the formwork main body when using a pin and wedge connector in the prior art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An aluminum alloy formwork that is convenient for disassembly and assembly, including a formwork main body, end edges are provided on the upper and lower sides of the formwork main body, side edges are provided on both sides of the formwork main body, two formwork main bodies form a 90° formwork, and there is a right-angle connecting frame between the two formwork main bodies. It also includes a top surface connector, and the top surface connector includes: A connecting component, the connecting component includes a rod body, the rod body passes through the side edge and the connecting hole at the top of the right-angle connecting frame, one end of the rod body has a head, and a main through groove is axially opened on the rod body, and the other end of the main through groove is a sealed end; A wedge, the wedge is located in the main through groove, the wedge includes a wedge-shaped piece and pressure pads located on both sides of the wedge-shaped piece. The wedge-shaped piece has a structure that is wider at the top and narrower at the bottom. One side of the pressure pad close to the wedge-shaped piece is a slope surface, and the other side of the pressure pad is a flat surface. A drag plate is provided at the lower end of the wedge-shaped piece. By hammering the drag plate, the wedge can be moved downward, and the wedge-shaped piece moves downward and exerts a lateral thrust on the pressure pads.

[0007] Further, the sealing end of the main through groove includes an arc-shaped tail. There are two sets of arc-shaped tails, which are respectively arranged on both sides of the rod body. A secondary through groove is formed between the two sets of arc-shaped tails. The two sets of arc-shaped tails can rotate along the center of the rod body, so that the secondary through groove is opposite or not opposite to the main through groove. When the secondary through groove is opposite to the main through groove, the wedge can be horizontally placed into the rod body. When the secondary through groove is not opposite to the main through groove, the arc-shaped tails are in a state of blocking the wedge.

[0008] Further, the sealing end of the main through groove is integrally formed with the rod body; When the wedge-shaped piece moves upward between the two sets of pressure pads, it can change the length of the wedge along the axial direction of the rod body, so that the wedge can pass through the main through groove from bottom to top.

[0009] Further, a limiting frame is provided in the area of the side edge opposite to the pressure pad. The pressure pad close to one side of the side edge is embedded in the limiting frame to limit the vertical radial movement of the limiting frame along the rod body.

[0010] Further, side ears are provided on one side of the pressure pad close to the flat surface. A spring is provided between two opposite side ears. A telescopic sleeve is sleeved inside the spring, and both ends of the telescopic sleeve are respectively fixed to the opposite side ears.

[0011] Further, two sets of second arc-shaped grooves are respectively opened on both circumferential sides of the rod body. A limiting arc frame is embedded in the second arc-shaped groove, and the limiting arc frame can rotate on the second arc-shaped groove; Two rows of limiting holes are opened on the wedge-shaped piece. The two rows of limiting holes are arranged staggeredly. The two rows of limiting holes are adapted to the opposite limiting arc frames. Any limiting arc frame is inserted into any one of the opposite limiting holes to limit the vertical radial movement of the wedge-shaped piece along the rod body.

[0012] Further, a convex part is provided on the pressure pad close to the sealing end of the rod body, and an empty area adapted to the convex part is provided on the sealing end.

[0013] Further, sliding grooves are respectively opened on both sides of the wedge-shaped piece. A sliding rail is provided on one side of the pressure pad close to the wedge-shaped piece. The axial length of the sliding rail along the rod body is less than the axial length of the sliding groove along the rod body.

[0014] Further, a retainer is further included. Guide rails are provided on both inner walls of the right-angle connecting frame, and the retainer can slide on the guide rails; Slope grooves are opened in the areas of both sides of the retainer opposite to the head. A slope adapted to the slope groove is provided on one side of the head close to the template body, so that the slope groove has a pre-tightening pressure on the head.

[0015] Furthermore, guiding grooves two are provided on both sides of the upper surface of the template body. A slidable moving block is arranged in the guiding groove two. A second spring is arranged between one side of the moving block away from the side edge and the guiding groove two. A plug is arranged at the other end of the moving block. A jack adapted to the plug is provided on the guiding track.

[0016] The present invention has the following beneficial effects: For the aluminum alloy template that is easy to disassemble and assemble, the wedge can be inserted into the connecting component from the end or below the connecting component, so that the space between the connecting component and the end edge does not need to be occupied. Therefore, when manufacturing the template body, the topmost connecting hole can be set as high as possible, strengthening the connection effect between the template body and the top of the right-angle connecting frame. And by directly hammering the drag plate with a hammer, when hammering the drag plate, the wedge-shaped piece can move downward. During the downward movement of the wedge-shaped piece, it can gradually apply a lateral thrust to the pressure pad, so that one pressure pad generates pressure on the side edge, and the other pressure pad generates pressure on the sealing end, thus locking the entire connecting component by the wedge, and then realizing the connection between the template body and the right-angle connecting frame. During the insertion and locking process of the wedge-shaped piece, the operator does not need to operate at the upper end of the wedge-shaped piece, so it is not affected by the end edge, and the position of the topmost connecting hole can be set as high as possible when manufacturing the template. Furthermore, the present invention can further strengthen the connection effect between the template body and the top of the right-angle connecting frame while ensuring easy disassembly and assembly.

[0017] Of course, when implementing any product of the present invention, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0020] Next, according to Figures 1 - 15 describe the easy-to-disassemble and assemble aluminum alloy template provided by the embodiments of the present invention.

[0021] Embodiment 1: Figure 1As shown, the wedge in the vertical hammering pin wedge connector 2 is used. After the connection is completed, all the formworks are reinforced by the tie rod 1. During the specific connection, the pin wedge connector 2 must be used at the topmost and bottommost ends of the formwork to ensure the stability of the formwork. At the top of the formwork body 7, due to the blockage of the end flange 71, when installing the pin wedge connector 2, the wedge needs to be inserted into the pin from top to bottom. Therefore, generally, a certain gap needs to be reserved between a connection hole 3 at the topmost of the formwork body 7 and the end flange 71 to provide space for the wedge to be inserted into the pin from top to bottom and for vertically hammering the upper end of the wedge. However, this method sacrifices the connection tightness at the topmost end of the formwork body 7, resulting in a lower position setting of the connection hole 3 at the uppermost layer, making it difficult to use the pin wedge connector 2 to connect the topmost end of the formwork body 7 and causing the connection at the upper end of the formwork to be not tight.

[0022] Please refer to Figure 2 and Figure 3 As shown in and, an aluminum alloy formwork that is easy to disassemble and assemble is provided in an embodiment of the present invention. The aluminum alloy formwork includes a formwork body 7. End flanges 71 are provided on the upper and lower sides of the formwork body 7, and side flanges 72 are provided on both sides of the formwork body 7. The connection holes 3 between the side flanges 72 of two adjacent formwork bodies 7 are connected by a pin wedge connector 2.

[0023] In the entire formwork system, the two formwork bodies 7 at the edge form a 90° formwork to construct the corner of the wall. During the construction of the formwork system, a right-angle connecting frame 8 needs to be coordinated between the two formwork bodies 7 at the edge. A pin wedge connector 2 is also provided between the right-angle connecting frame 8 and the formwork body 7 at the edge. During operation, only the pin needs to be passed through the connection hole 3 and the wedge is hammered from top to bottom to achieve fixation.

[0024] A top surface connector is provided here. The top surface connector is used to connect the connection holes 3 at the uppermost layer between two formworks and to connect the formwork at the edge with the right-angle connecting frame 8. The structure of the top surface connector will be specifically introduced below with the connection between the formwork at the edge and the right-angle connecting frame 8 as an example.

[0025] Refer to Figure 4 and Figure 5As shown, the above-mentioned top surface connecting member includes a connecting component 6. The connecting component 6 includes a rod body 61 and a wedge. One end of the rod body 61 has a head 62. The rod body 61 passes through the connecting hole 3 at the top of the right-angle connecting frame 8 and the side edge 72, while the head 62 cannot pass through the connecting hole 3. The rod body 61 is axially provided with a main through groove 64, and the other end of the main through groove 64 is a sealed end. The wedge is located in the main through groove 64. The wedge includes a wedge-shaped piece 5 and pressure pads 4 on both sides of the wedge-shaped piece 5. The wedge-shaped piece 5 has a structure that is wider at the top and narrower at the bottom. One side of the pressure pad 4 close to the wedge-shaped piece 5 is a slope surface, and the other side of the pressure pad 4 is a flat surface. Specifically, the pressure pad 4 has a structure that is narrower at the top and wider at the bottom. A drag plate 52 is provided at the lower end of the wedge-shaped piece 5. During operation, the wedge-shaped piece 5 can be moved downward by directly hammering the drag plate 52. During the downward movement of the wedge-shaped piece 5, it can gradually exert a lateral thrust on the pressure pad 4, so that one pressure pad 4 generates pressure on the side edge 72, and the other pressure pad 4 generates pressure on the sealed end, thereby locking the entire wedge to the connecting component 6.

[0026] Since there is a drag plate 52 at the lower end of the wedge-shaped piece 5, the wedge here is not inserted into the main through groove 64 from the upper direction of the main through groove 64. Therefore, during operation, there is no need to worry about the problem that the wedge-shaped piece 5 and the pressure pad 4 cannot be inserted into the main through groove 64 from top to bottom due to the blockage of the end edge 71.

[0027] Therefore, when connecting the connection hole 3 at the topmost layer of the aluminum alloy formwork provided by the present invention, which is convenient for disassembly and assembly, the drag plate 52 can be directly hammered with a hammer. When hammering the drag plate 52, the wedge-shaped piece 5 can be moved downward. During the downward movement of the wedge-shaped piece 5, it can gradually exert a lateral thrust on the pressure pad 4, so that one pressure pad 4 generates pressure on the side edge 72, and the other pressure pad 4 generates pressure on the sealed end, thereby locking the entire wedge to the connecting component 6, and then realizing the connection between the formwork main body 7 and the right-angle connecting frame 8. During the insertion and locking process of the wedge-shaped piece 5, the operator does not need to operate at the upper end of the wedge-shaped piece 5, so it is not affected by the end edge 71. The position of the topmost connection hole 3 can be set as high as possible during the manufacture of the formwork, which can further strengthen the connection effect between the formwork main body 7 and the top of the right-angle connecting frame 8.

[0028] Refer to Figures 5 - 9As shown, based on the above solution, in order to prevent the wedge from being inserted into the main through groove 64 from above the main through groove 64, in this embodiment, the wedge is inserted into the main through groove 64 from the side end of the main through groove 64. Specifically, the sealing end includes an arc-shaped tail 63, which is substantially composed of an arc-shaped cylinder and a conical cylinder. The conical cylinder is located at one end of the arc-shaped cylinder away from the rod body 61 and serves as the end where the entire connecting component 6 is initially inserted into the connecting hole 3. There are two groups of arc-shaped tails 63, which are respectively arranged on both sides of the rod body 61. A secondary through groove 66 is formed between the two groups of arc-shaped tails 63. The two groups of arc-shaped tails 63 can rotate along the center of the rod body 61 to make the secondary through groove 66 opposite or not opposite to the main through groove 64. When the secondary through groove 66 is opposite to the main through groove 64, referring to Figure 8 the state shown, at this time, the wedge can be horizontally placed into the main through groove 64 from the secondary through groove 66, so that the wedge is located inside the rod body 61; conversely, after rotating the arc-shaped tail 63 by 90°, the secondary through groove 66 is not opposite to the main through groove 64, referring to Figure 7 the state shown. At this time, the arc-shaped tail 63 is in a state of blocking the wedge. At this time, during the downward movement of the wedge-shaped piece 5, the pressure pad 4 can exert pressure on the arc-shaped tail 63 and the side edge 72, thereby locking the position of the connecting component 6, making the template body 7 and the right-angle connecting frame 8.

[0029] Therefore, the wedge of the aluminum alloy template that is easy to disassemble and assemble provided by the embodiment of the present invention can be inserted into the connecting component 6 from the end of the connecting component 6, so that the space between the connecting component 6 and the end edge 71 does not need to be occupied. Therefore, when manufacturing the template body 7, the topmost connecting hole 3 can be set as high as possible, strengthening the connection effect between the top of the template body 7 and the right-angle connecting frame 8.

[0030] Preferably, in order to enable the arc-shaped tail 63 to rotate on the rod body 61, a first arc-shaped groove 631 is provided on the side of the arc-shaped tail 63 close to the rod body 61, and a first arc-shaped rail 611 is provided on the side of the rod body 61 close to the arc-shaped tail 63. By manually rotating the arc-shaped tail 63, the state of the arc-shaped tail 63 can be changed from Figure 7 the state to Figure 8 the state, or from Figure 8 the state to Figure 7 the state.

[0031] Such as Figure 10Preferably, in order to prevent the pressure pad 4 from being forced to move downward when the hammer strikes the slide plate 52, a limiting frame 11 is provided in the area of the side edge 72 opposite to the pressure pad 4. The size and shape of the limiting frame 11 are adapted to the pressure pad 4, so that when initially assembled, the pressure pad 4 is directly inserted into the limiting frame 11, and the pressure pad 4 on the side close to the side edge 72 is embedded in the limiting frame 11. The limiting frame 11 can limit the movement of the pressure pad 4 along the vertical direction of the rod body 61, thereby ensuring that the pressure pad 4 can only move horizontally during the downward movement of the wedge piece 5.

[0032] Furthermore, in order to ensure that the pressure pad 4 on the side close to the arc-shaped tail 63 does not displace downward either, a convex portion 44 is provided on the pressure pad 4 close to the arc-shaped tail 63 of the rod body 61, and an empty area adapted to the convex portion 44 is provided on the sealing end. Thus, when initially assembled, the convex portion 44 on the side close to the arc-shaped tail 63 is inserted into the empty area to limit the up-and-down displacement of the pressure pad 4 on this side. In this embodiment, when the arc-shaped tail 63 rotates to Figure 7 the state shown, the middle part of its first arc-shaped groove 631 serves as the empty area.

[0033] Referring to Figure 5 、 Figure 6 and Figure 12 shown, in order to make the whole wedge an integral structure and facilitate directly feeding the two into the main through groove 64 during operation, side ears 41 are provided on the side of the pressure pad 4 close to the flat surface. A spring 43 is provided between two opposite side ears 41. A telescopic sleeve 42 is sleeved inside the spring 43, and both ends of the telescopic sleeve 42 are fixed to the opposite side ears 41 respectively, so that the two pressure pads 4 form an integral body. The telescopic sleeve 42 is a common sleeve-type telescopic part in the prior art, which is a structure with a smaller tube sleeved inside a larger tube, and will not be elaborated here; and sliding grooves 53 are provided on both sides of the wedge piece 5, and sliding rails 45 adapted to the sliding grooves 53 are provided on the pressure pad 4, so as to ensure that the wedge piece 5 and the pressure pad 4 can form an integral body.

[0034] Preferably, side ears 41 are provided on both the upper and lower sides of the pressure pad 4, that is, two sets of springs 43 are also provided. This way makes the two pressure pads 4 more stable.

[0035] During specific use, when the wedge is assembled, the wedge piece 5 will become loose due to external vibration. In order to prevent the situation that the connection between the template main body 7 and the right-angle connecting frame 8 is not tight due to loosening, two sets of second arc-shaped grooves 612 are provided on both circumferential sides of the rod body 61. Referring to Figure 7 it can be better understood that there are a total of four second arc-shaped grooves 612. A limiting arc frame 65 is embedded in the second arc-shaped grooves 612. The limiting arc frame 65 can rotate on the second arc-shaped grooves 612, and its rotation can form Figure 5the state shown or Figure 7 the state shown; two rows of limiting holes 51 are formed in the wedge-shaped piece 5, and the two rows of limiting holes 51 are arranged staggeredly. The two rows of limiting holes 51 are adapted to the opposite limiting arc frames 65. Any limiting arc frame 65 is inserted into any one of the limiting holes 51 opposite thereto to limit the wedge-shaped piece 5 from moving along the vertical radial direction of the rod body 61. For example Figure 5 when the two limiting arc frames 65 on the left side in [[ ]] are rotated into any one of the limiting holes 51 of the set of limiting holes 51 on the left side, the movement of the wedge-shaped piece 5 in the vertical direction can be restricted.

[0036] It should be noted that the reason for setting two rows of limiting arc frames 65 and two rows of staggered limiting holes 51 is that in this way, there can be more hole positions in the vertical direction, improving the alignment rate of the limiting arc frames 65.

[0037] Referring to Figure 4 、 Figure 12 and Figure 13 shown, in order to further improve the stability of the connecting member 6 and avoid the loosening caused by external vibration, a retainer 10 is also provided here. The retainer 10 shown in the figure is a trapezoidal block, which is placed in the right-angle area of the right-angle connecting frame 8. Guide rails 721 are provided on both inner walls of the right-angle connecting frame 8. A first guide groove 102 adapted to the guide rail 721 is provided on the retainer 10, so that it can slide on the guide rail 721. Preferably, widened structures are provided at both the upper and lower ends of the guide rail 721 to prevent the retainer 10 from derailing.

[0038] Slope grooves 101 are formed in the areas on both sides of the retainer 10 opposite to the head 62. A slope adapted to the slope groove 101 is provided on one side of the head 62 close to the template body 7. During assembly, first, the retainer 10 is pushed downward until the retainer 10 is located at the lowermost part of the guide rail 721. After the connecting member 6 is assembled, the retainer 10 is pushed upward again, so that the slope groove 101 has a pre-tightening pressure on the head 62, improving the stability of the entire connecting member 6.

[0039] Preferably, in order to improve the stability of the retainer 10, a locking member 9 is also provided, which includes: guide grooves 103 are formed on both sides of the upper surface of the template body 7. Slidable moving blocks 91 are provided in the guide grooves 103. A second spring 92 is provided between the side of the moving block 91 away from the side edge 72 and the guide groove 103. The other end of the moving block 91 is provided with a plug 93. A jack 722 adapted to the plug 93 is formed in the guide rail 721. When the plug 93 is inserted into the jack 722, the downward movement of the retainer 10 can be restricted, thereby ensuring the stability of the retainer 10.

[0040] When assembling the connecting member 6: Step 1: First, push the retainer 10 downward so that the retainer 10 is located at the lowermost part of the guiding track 721. Then, pass the rod body 61 through the uppermost connecting hole 3. The head 62 cannot pass through the connecting hole 3. Then, rotate the arc-shaped tail 63 so that the auxiliary passing groove 66 and the main passing groove 64 face downward relative to each other, and pull the wedge piece 5 in the wedge to be assembled upward to the uppermost position. Press the two pressure pads 4 with fingers so that the spring 43 is compressed, and the width of the whole wedge is reduced, forming Figure 14 the state of (a) in Step 2: Feed the wedge into the main passing groove 64 from the position of the auxiliary passing groove 66, and make one of the pressure pads 4 enter the limiting frame 11, forming Figure 14 the state of (b) in Step 3: Rotate the arc-shaped tail 63 so that the auxiliary passing groove 66 and the main passing groove 64 are staggered, forming Figure 14 the state of (c) in Step 4: Release the pressure pad 4 pressed by the finger, so that the spring 43 rebounds, and pull the wedge piece 5 downward through the drag plate 52, so that the convex part 44 is inserted into the first arc groove 631, forming Figure 14 the state of (d) in Step 5: Use a hammer to strike the drag plate 52, so that the wedge piece 5 applies pressure to the pressure pads 4 on both sides, so that the wedge fixes the connecting component 6, forming Figure 14 the state of (e) in Step 6: Rotate the limiting arc frame 65 that can be inserted into the corresponding limiting hole 51, so that the limiting arc frame 65 locks the height of the wedge piece 5 to prevent it from loosening, referring to Figure 14 the state of (f) in

[0041] Step 7: Push the retainer 10 upward so that the slope groove 101 has a pre-tightening pressure on the head 62, improving the stability of the whole connecting component 6. When the retainer 10 is in place, the plug 93 is inserted into the jack 722, which can limit the downward movement of the retainer 10, thus ensuring the stability of the retainer 10.

[0042] During disassembly, it includes the following steps: Step 1: Manually pull the moving block 91 so that the spring two 92 is compressed, the plug 93 is disengaged from the jack 722, and push the retainer 10 downward so that the retainer 10 is disengaged from the connecting component 6 downward; Step 2: Rotate the limiting arc frame 65 in the reverse direction so that it disengages from the limiting hole 51, then hammer the drag plate 52 upward from the bottom of the drag plate 52 so that the drag plate 52 moves upward. Press the pressure pad 4 near the arc-shaped tail 63 with fingers so that the convex part 44 disengages from the first arc rail 611, and rotate the arc-shaped tail 63 so that the auxiliary passing groove 66 and the main passing groove 64 are opposite again, and then take out the wedge from the auxiliary passing groove 66.

[0043] Embodiment 2: As Figure 15 , the difference between this embodiment and the first embodiment lies in the different ways of feeding the wedge into the main through groove 64. Specifically, the sealing end of the main through groove 64 is integrally formed with the rod body 61. When the wedge-shaped piece 5 moves upward between the two groups of pressure pads 4, it can change the length of the wedge along the axial direction of the rod body 61, reducing the width of the entire wedge, so that the wedge can pass through the main through groove 64 from bottom to top, that is, the wedge in this solution enters the inside of the main through groove 64 from bottom to top; in addition, it should be noted that since the wedge enters the main through groove 64 from bottom to top, the side ears 41 are only provided at the lower part of the pressure pad 4 to avoid the upper side ears 41 blocking the wedge from passing through the main through groove 64 from bottom to top.

[0044] When assembling the connecting component 6: Step 1: First, push the retainer 10 downward so that the retainer 10 is located at the lowermost part of the guiding track 721. Then, pass the rod body 61 through the uppermost connecting hole 3, and the head 62 cannot pass through the connecting hole 3. Then, pull the wedge-shaped piece 5 in the wedge to be assembled upward to the uppermost position, and press the two pressure pads 4 with fingers so that the spring 43 is compressed and the width of the entire wedge is reduced; Step 2: Feed the wedge into the main through groove 64 from the bottom upward, and laterally move the wedge so that one of the pressure pads 4 enters the inside of the limit frame 11; Step 3: Release the pressure pad 4 pressed by the finger, so that the spring 43 rebounds, and pull the wedge-shaped piece 5 downward through the drag plate 52 so that the convex part 44 is inserted into the empty area opened in the sealing end. The empty area in this embodiment should be a hole-shaped structure provided in the sealing end; Step 4: Use a hammer to strike the drag plate 52 so that the wedge-shaped piece 5 applies pressure to the two pressure pads 4 on both sides, so that the wedge fixes the connecting component 6; Step 5: Rotate the limit arc frame 65 that can be inserted into the corresponding limit hole 51 so that the limit arc frame 65 locks the height of the wedge-shaped piece 5 to prevent it from loosening; Step 6: Push the retainer 10 upward so that the slope groove 101 has a pre-tightening pressure on the head 62, improving the stability of the entire connecting component 6. When the retainer 10 is in place, the plug 93 is inserted into the jack 722, which can limit the downward movement of the retainer 10, thus ensuring the stability of the retainer 10.

[0045] When disassembling, it includes the following steps: Step 1: Manually pull the moving block 91 so that the spring two 92 is compressed, the plug 93 is disengaged from the jack 722, and push the retainer 10 downward so that the retainer 10 is disengaged from the connecting component 6 downward; Step 2: Rotate the limiting arc frame 65 in the reverse direction to disengage it from the limiting hole 51, then hammer the platen 52 upward to move the platen 52 upward, thereby reducing the distance between the two pressure pads 4, causing the convex part 44 to disengage from the first arc rail 611, and pulling the wedge body downward as a whole to disengage from the main through groove 64.
