Abstract

The present invention discloses an aluminum alloy formwork that is easy to disassemble and assemble, and relates to the technical field of aluminum formwork systems. The aluminum alloy formwork that is easy to disassemble and assemble comprises a formwork body, wherein the upper and lower sides of the formwork body are provided with end edges, and the two sides of the formwork body are provided with side edges. Two formwork bodies form a 90° formwork, and a right-angle connecting frame is provided between the two formwork bodies. The aluminum alloy formwork that is easy to disassemble and assemble can be directly hammered with a hammer. When the hammer is struck on the drag plate, the wedge piece can be moved downward. During the downward movement of the wedge 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, so that the entire wedge locks the connecting component. This makes the present invention not only easy to disassemble and assemble, but also further strengthens the connection effect between the formwork body and the top of the right-angle connecting frame.

Description

Technical Field

[0001] The invention relates to the technical field of aluminum template systems, in particular to an aluminum alloy template that is easy to assemble and disassemble. Background Art

[0002] The aluminum alloy formwork system consists of an aluminum formwork body and various connection accessories, among which the most commonly used are pin wedge connections.

[0003] During operation, the wedge in the pin wedge connector is generally directly used to vertically hammer. After the connection is completed, all the formwork is reinforced by pull rods. However, during the specific connection, the top and bottom ends of the formwork must be connected using pin wedge connectors to ensure the stability of the formwork. At the top of the formwork body, due to the obstruction of the end edge, when installing the pin wedge connector, the wedge needs to be inserted into the pin from top to bottom. Therefore, a certain gap is generally required between a connection hole at the top of the formwork body and the end edge to reserve 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 tightness of the connection at the top end of the formwork body, which causes the position of the topmost connection hole to be set lower, making it difficult to use the pin wedge connector to connect the top end of the formwork body, resulting in a loose connection at the top end of the formwork.

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

[0005] In view of the deficiencies of the prior art, the present invention provides an aluminum alloy template that is easy to disassemble and assemble, solving the problem of poor connection tightness at the upper end of the template body when connecting with pin wedge connectors in the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an aluminum alloy template that is easy to disassemble and assemble, including a template body, end edges are provided on the upper and lower sides of the template body, side edges are provided on both sides of the template body, two template bodies form a 90° template, a right-angle connecting frame is provided between the two template bodies, and a top surface connecting member is also included, and the top surface connecting member includes:

[0007] The connecting component includes a rod body, the rod body passing through the connecting hole between the side edge and the top of the right-angle connecting frame, one end of the rod body having a head, the rod body having a main groove formed along the axial direction, and the other end of the main groove being a sealed end;

[0008] The wedge is located in the main groove. The wedge includes a wedge-shaped piece and pressure pads located on both sides of the wedge. The wedge is a wide-upper-narrow-lower structure. The side of the pressure pad close to the wedge is a slope, and the other side of the pressure pad is a flat surface. A drag plate is provided at the lower end of the wedge. The wedge can be moved downward by hammering the drag plate. The wedge moves downward and applies a lateral thrust to the pressure pad.

[0009] Furthermore, the sealing end of the main groove includes an arc-shaped tail, and two groups of the arc-shaped tails are provided, which are arranged on both sides of the rod body respectively, and an auxiliary groove is formed between the two groups of arc-shaped tails. The two groups of arc-shaped tails can rotate along the center of the rod body so that the auxiliary groove is opposite to or not opposite to the main groove. When the auxiliary groove is opposite to the main groove, the wedge can be placed horizontally into the rod body. When the auxiliary groove is not opposite to the main groove, the arc-shaped tail is in a state of blocking the wedge.

[0010] Furthermore, the sealing end of the main groove is integrally formed with the rod body;

[0011] The wedge-shaped piece moves upward between the two sets of pressure pads to change the length of the wedge along the axial direction of the rod body, so that the wedge can pass through the main groove from bottom to top.

[0012] Furthermore, a limit frame is provided on the side edge in an area opposite to the pressure pad, and the pressure pad close to the side edge is embedded in the limit frame to limit the limit frame from moving along the vertical radial direction of the rod body.

[0013] Furthermore, the pressure pad is provided with a side ear on one side close to the flat surface, a spring is provided between the two opposite side ears, a telescopic sleeve is provided inside the spring, and both ends of the telescopic sleeve are respectively fixed on the opposite side ears.

[0014] Furthermore, two sets of second arc-shaped grooves are provided on both sides of the circumference of the rod body, and 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;

[0015] The wedge-shaped piece is provided with two rows of limiting holes, which are staggered and matched with relative limiting arc frames. Any limiting arc frame is inserted into any relative limiting hole to limit the vertical radial movement of the wedge-shaped piece along the rod body.

[0016] Furthermore, a convex portion is provided on the pressure pad close to the sealing end of the rod body, and a hollow area adapted to the convex portion is provided on the sealing end.

[0017] Furthermore, both sides of the wedge-shaped piece are provided with a slide groove, and the side of the pressure pad close to the wedge-shaped piece is provided with a slide rail, and the axial length of the slide rail along the rod body is shorter than the axial length of the slide groove along the rod body.

[0018] Furthermore, it also includes a retainer, and both inner walls of the right-angle connecting frame are provided with guide rails, and the retainer can slide on the guide rails;

[0019] The areas on both sides of the retainer opposite to the head are provided with slope grooves, and the side of the head close to the template body is provided with a slope adapted to the slope groove, so that the slope groove has pre-tightening pressure on the head.

[0020] Furthermore, two guide grooves are provided on both sides of the upper surface of the template body, a sliding movable block is provided in the two guide grooves, a spring is provided between the side of the movable block away from the side edge and the two guide grooves, a plug is provided at the other end of the movable block, and a socket adapted to the plug is provided on the guide rail.

[0021] The present invention has the following beneficial effects:

[0022] In this aluminum alloy formwork that is easy to disassemble and assemble, the wedge can be inserted into the connecting component from the end or bottom of the connecting component, thereby not occupying the space between the connecting component and the end edge. Therefore, when the formwork body is manufactured, the topmost connecting hole can be positioned as high as possible, thereby strengthening the connection between the formwork body and the top of the right-angle connecting frame. Furthermore, by directly striking the drag plate with a hammer, the wedge piece can be moved downward. During the downward movement of the wedge piece, it can gradually apply a lateral thrust to the pressure pads, causing one pressure pad to exert pressure on the side edge and the other pressure pad to exert pressure on the sealing end, thereby locking the entire wedge to the connecting component and subsequently achieving the connection between the formwork body and the right-angle connecting frame. During the insertion and locking process of the wedge piece, the operator does not need to operate at the upper end of the wedge piece, so that it is not affected by the end edge. Therefore, the position of the topmost connecting hole can be positioned as high as possible when the formwork body is manufactured, thereby ensuring easy disassembly and assembly while further strengthening the connection between the formwork body and the top of the right-angle connecting frame.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The following is based on Figures 1-15 The invention describes an aluminum alloy template that is easy to disassemble and assemble, provided by an embodiment of the invention.

[0041] Example 1:

[0042] Figure 1 As shown, the wedge in the pin wedge connector 2 is vertically hammered. After the connection is completed, all the formwork is reinforced by the pull rod 1. During the specific connection, the top and bottom ends of the formwork must be connected using the pin wedge connector 2 to ensure the stability of the formwork. At the top of the formwork body 7, due to the obstruction of the end edge 71, when installing the pin wedge connector 2, the wedge needs to be inserted into the pin from top to bottom. Therefore, a certain gap is generally reserved between a connection hole 3 at the top of the formwork body 7 and the end edge 71 to reserve 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 of the upper end of the formwork body 7, which causes the position of the uppermost connection hole 3 to be set lower, making it difficult to use the pin wedge connector 2 to connect the upper end of the formwork body 7, resulting in a loose connection at the upper end of the formwork.

[0043] See also Figure 2 and Figure 3 As shown, an embodiment of the present invention provides an aluminum alloy template that is easy to disassemble and assemble. The aluminum alloy template includes a template body 7, and the upper and lower sides of the template body 7 are provided with end edges 71, and the two sides of the template body 7 are provided with side edges 72. The connecting holes 3 of the side edges 72 of two adjacent template bodies 7 are connected by a pin wedge connector 2.

[0044] In the entire formwork system, the two formwork bodies 7 at the edge form a 90° formwork, thereby constructing the corner of the wall. In constructing the formwork system, a right-angle connecting frame 8 is required between the two formwork bodies 7 at the edge, and a pin wedge connecting member 2 is also provided between the right-angle connecting frame 8 and the formwork body 7 at the edge. During operation, it is only necessary to pass the pin through the connecting hole 3 and then knock the wedge from top to bottom to achieve fixation.

[0045] A top surface connector is provided here, which is used to connect the topmost connection holes 3 between the two templates, and to connect the edge template and the right-angle connecting frame 8. The structure of the top surface connector is specifically introduced below using the connection between the edge template and the right-angle connecting frame 8 as an example.

[0046] Reference Figure 4 and Figure 5 As shown, the top surface connector mentioned above includes a connecting part 6, which includes a rod body 61 and a wedge. One end of the rod body 61 has a head 62, and the rod body 61 passes through the connecting hole 3 at the top of the side edge 72 and the right-angle connecting frame 8, while the head 62 cannot pass through the connecting hole 3, and the rod body 61 is provided with a main groove 64 along the axial direction, and the other end of the main groove 64 is a sealed end. The wedge is located in the main groove 64, and the wedge includes a wedge-shaped piece 5 and pressure pads 4 located on both sides of the wedge piece 5. The wedge piece 5 is a wide-upper-narrow-lower structure. The side of the force pad 4 close to the wedge piece 5 is a sloped surface, and the other side of the pressure pad 4 is a flat surface. Specifically, the pressure pad 4 is a structure that is narrow at the top and wide at the bottom. A drag plate 52 is provided at the lower end of the wedge piece 5. During operation, the wedge piece 5 can be moved downward directly by hammering the drag plate 52. In the process of the wedge piece 5 moving downward, it can gradually apply a lateral thrust to 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 sealing end, so that the entire wedge locks the connecting component 6.

[0047] Since the lower end of the wedge piece 5 has a drag plate 52, the wedge here is not inserted into the main groove 64 from above the main groove 64. Therefore, during operation, there is no need to worry about the problem that the wedge piece 5 and the pressure pad 4 cannot be inserted into the main groove 64 from top to bottom due to the obstruction of the end edge 71.

[0048] Therefore, when the connection hole 3 of the top layer of the aluminum alloy formwork that is easy to disassemble and assemble provided by the present invention is connected, the drag plate 52 can be directly hammered with a hammer. When hammering the drag plate 52, the wedge piece 5 can be moved downward. In the process of the wedge piece 5 moving downward, it can gradually apply a lateral thrust to the pressure pad 4, so that one pressure pad 4 produces pressure on the side edge 72, and the other pressure pad 4 produces pressure on the sealing end, so that the entire wedge locks the connecting component 6, and then realizes the connection between the formwork body 7 and the right-angle connecting frame 8. During the insertion and locking process of the wedge piece 5, the operator does not need to operate at the upper end of the wedge piece 5, so that it is not affected by the end edge 71. The position of the topmost connection hole 3 can be set as high as possible when making the formwork, thereby further strengthening the connection effect between the formwork body 7 and the top of the right-angle connecting frame 8.

[0049] Reference Figure 5-Figure 9 As shown, based on the above scheme, in order to achieve that the above wedge is not inserted into the main groove 64 from the direction above the main groove 64, this embodiment adopts the method of inserting the main groove 64 from the side end of the main groove 64. Specifically, the sealing end includes an arc tail 63, which is essentially composed of an arc-shaped column and a tapered column. The tapered column is located at the end of the arc-shaped column away from the rod body 61, as the end of the entire connecting component 6 initially inserted into the connecting hole 3. The arc tail 63 is provided with two groups, which are respectively arranged on both sides of the rod body 61. Auxiliary grooves 66 are formed between the two groups of arc tails 63. The two groups of arc tails 63 can rotate along the center of the rod body 61 so that the auxiliary grooves 66 are opposite to or not opposite to the main grooves 64. When the auxiliary grooves 66 are opposite to the main grooves 64, refer to Figure 8 In the state shown, the wedge can be placed horizontally from the auxiliary groove 66 into the main groove 64 so that the wedge is located in the rod body 61; on the contrary, after the arc tail 63 is rotated 90°, the auxiliary groove 66 and the main groove 64 are not opposite, refer to Figure 7 In the state shown, the arc tail 63 is in the state of blocking the wedge. At this time, during the downward movement of the wedge piece 5, the pressure pad 4 can generate pressure on the arc tail 63 and the side edge 72, and then lock the position of the connecting part 6, so that the template body 7 and the right-angle connecting frame 8 are connected.

[0050] Therefore, the wedge of the aluminum alloy formwork that is easy to disassemble and assemble provided in the embodiment of the present invention can be inserted into the connecting part 6 from the end of the connecting part 6, so that it is not necessary to occupy the space between the connecting part 6 and the end edge 71. Therefore, when making the formwork body 7, the topmost connecting hole 3 can be set as high as possible, thereby strengthening the connection effect between the formwork body 7 and the top of the right-angle connecting frame 8.

[0051] Preferably, in order to realize that the arc tail 63 can rotate on the rod body 61, a first arc groove 631 is provided on the side of the arc tail 63 close to the rod body 61, and a first arc rail 611 is provided on the side of the rod body 61 close to the arc tail 63. By manually rotating the arc tail 63, the state of the arc tail 63 can be changed from Figure 7 The state reaches Figure 8 status, or by Figure 8 The state reaches Figure 7 status.

[0052] like Figure 10 As shown, in order to avoid the situation where the pressure pad 4 is also forced to move downward when the hammer hits the drag plate 52, a limit frame 11 is provided on the side edge 72 in the area opposite to the pressure pad 4. The setting size and shape of the limit frame 11 are adapted to the pressure pad 4, so that during the initial assembly, the pressure pad 4 is directly sent into the limit frame 11, and the pressure pad 4 close to the side edge 72 is embedded in the limit frame 11. The limit frame 11 can limit the movement of the limit frame 11 along the vertical direction of the rod body 61, thereby ensuring that the pressure pad 4 can only move laterally during the downward movement of the wedge piece 5.

[0053] Furthermore, in order to ensure that the pressure pad 4 near the arc-shaped tail 63 does not move downward, a convex portion 44 is provided on the pressure pad 4 near the arc-shaped tail 63 of the rod body 61, and a hollow area adapted to the convex portion 44 is provided on the sealing end. Therefore, during the initial assembly, the convex portion 44 near the arc-shaped tail 63 is inserted into the hollow area to limit the upward and downward displacement of the pressure pad 4 on this side. In this embodiment, when the arc-shaped tail 63 rotates to Figure 7 In the state shown, the middle portion of the first arc-shaped groove 631 serves as an empty area.

[0054] Reference Figure 5 、 Figure 6 and Figure 12 As shown, in order to realize the integrated structure of the entire wedge, the two can be directly fed into the main groove 64 together for easy operation. Here, a side ear 41 is provided on the side of the pressure pad 4 close to the flat surface, and a spring 43 is provided between the two opposite side ears 41. A telescopic sleeve 42 is provided in the spring 43, and the two ends of the telescopic sleeve 42 are respectively fixed on the opposite side ears 41, so that the two pressure pads 4 are formed into one. The telescopic sleeve 42 is a common sleeve-type telescopic part in the prior art, which is a structure in which a smaller tube body is sleeved in a larger tube body, which will not be described here; and slide grooves 53 are provided on both sides of the wedge piece 5, and slide rails 45 adapted to the slide 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 a whole.

[0055] Preferably, side ears 41 are provided on the upper and lower sides of the pressure pad 4, that is, two groups of springs 43 are also provided. This approach makes the two pressure pads 4 more stable.

[0056] In actual use, after the wedge is assembled, the wedge piece 5 will become loose due to external vibration. In order to avoid the loose connection between the template body 7 and the right-angle connecting frame 8, two sets of second arc grooves 612 are provided on both sides of the circumference of the rod body 61. Figure 7 It can be better understood that there are four second arc grooves 612, and a limiting arc frame 65 is embedded in the second arc groove 612. The limiting arc frame 65 can rotate on the second arc groove 612, and its rotation can form Figure 5 The status shown or Figure 7 The state shown; two rows of limiting holes 51 are opened on the wedge-shaped piece 5, and the two rows of limiting holes 51 are staggered. The two rows of limiting holes 51 are adapted to the relative limiting arc frame 65. Any limiting arc frame 65 is inserted into any relative limiting hole 51 for limiting the vertical radial movement of the wedge-shaped piece 5 along the rod body 61, for example Figure 5 The two limiting arc brackets 65 on the middle left side rotate to any one of the limiting holes 51 of the group of limiting holes 51 on the left side, thereby limiting the movement of the wedge-shaped piece 5 in the vertical direction.

[0057] It should be noted that the reason for providing two rows of limiting arc frames 65 and two rows of staggered limiting holes 51 is that more holes can be provided in the vertical direction, thereby improving the alignment rate of the limiting arc frames 65 .

[0058] Reference Figure 4 、 Figure 12 and Figure 13 As shown, in order to further improve the stability of the connecting component 6 and avoid its loosening due to 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 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 the upper and lower ends of the guide rail 721 to prevent the retainer 10 from derailing.

[0059] Slope grooves 101 are provided on both sides of the retainer 10 in the areas opposite to the head 62, and a slope that matches the slope groove 101 is provided on the side of the head 62 close to the template body 7. During assembly, the retainer 10 is first pushed downward so that the retainer 10 is located at the bottom of the guide rail 721. After the connecting component 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, thereby improving the stability of the entire connecting component 6.

[0060] Preferably, in order to improve the stability of the retainer 10, a locking member 9 is also provided, which includes: a guide groove 2 103 is provided on both sides of the upper surface of the template body 7, a slidable movable block 91 is provided in the guide groove 2 103, a spring 2 92 is provided between the side of the movable block 91 away from the side edge 72 and the guide groove 2 103, a plug 93 is provided at the other end of the movable block 91, and a socket 722 adapted to the plug 93 is provided on the guide rail 721. When the plug 93 is inserted into the socket 722, the retainer 10 can be restricted from moving downward, thereby ensuring the stability of the retainer 10.

[0061] When assembling connecting part 6:

[0062] Step 1: First, push the retainer 10 downwards to locate it at the bottom of the guide rail 721. Then, pass the rod 61 through the uppermost connection hole 3. The head 62 cannot pass through the connection hole 3. Then, rotate the arc tail 63 to pull the auxiliary groove 66 and the main groove 64 downwards relative to each other. Pull the wedge piece 5 in the wedge to be assembled upwards to the top. Press the two pressure pads 4 with your fingers to compress the spring 43. The width of the entire wedge is reduced to form Figure 14 (a) state in;

[0063] Step 2: Feed the wedge from the auxiliary slot 66 into the main slot 64, and make one of the pressure pads 4 enter the limit frame 11 to form Figure 14 The state of (b);

[0064] Step 3: Rotate the arc tail 63 to stagger the auxiliary slot 66 and the main slot 64 to form Figure 14 (c) state in;

[0065] Step 4: Release the pressure pad 4 pressed by the finger to make the spring 43 rebound, and pull the wedge 5 downward through the drag plate 52 to insert the protrusion 44 into the first arc groove 631 to form Figure 14 the state of (d);

[0066] Step 5: Use a hammer to hit the drag plate 52, so that the wedge 5 applies pressure to the pressure pads 4 on both sides, so that the wedge fixes the connecting part 6 to form Figure 14 the state of (e);

[0067] 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 5 to prevent it from loosening. Figure 14 The state of (f).

[0068] Step 7: Push the retainer 10 upward so that the slope groove 101 has a pre-tightening pressure on the head 62, thereby improving the stability of the entire connecting component 6. When the retainer 10 is in place, the plug 93 is inserted into the socket 722, which can limit the downward movement of the retainer 10, thereby ensuring the stability of the retainer 10.

[0069] During disassembly, the following steps are involved:

[0070] Step 1: Manually pull the moving block 91 to compress the second spring 92, disengage the plug 93 from the socket 722, and push the retainer 10 downward to disengage the retainer 10 downward from the connecting component 6;

[0071] Step 2: Reversely rotate the limiting arc bracket 65 to disengage it from the limiting hole 51, then hammer the carriage 52 upward from the bottom to move the carriage 52 upward, press the pressure pad 4 near the side of the arc tail 63 with your fingers to disengage the protrusion 44 from the first arc rail 611, and rotate the arc tail 63 to make the auxiliary slot 66 and the main slot 64 face each other again, and then remove the wedge from the auxiliary slot 66.

[0072] Example 2:

[0073] like Figure 15 This embodiment differs from the first embodiment in that the wedge is fed into the main slot 64 in a different manner. Specifically, the sealed end of the main slot 64 is integrally formed with the rod body 61. The upward movement of the wedge-shaped piece 5 between the two sets of pressure pads 4 can change the axial length of the wedge along the rod body 61, reducing the width of the entire wedge, thereby allowing the wedge to pass through the main slot 64 from bottom to top. That is, the wedge in this embodiment enters the main slot 64 from bottom to top. It should also be noted that because the wedge enters the main slot 64 from bottom to top, the side ears 41 are only provided on the lower portion of the pressure pad 4 to avoid the upper side ears 41 being provided, which would prevent the upper side ears 41 from blocking the wedge from passing through the main slot 64 from bottom to top.

[0074] When assembling connecting part 6:

[0075] Step 1: First, push the retainer 10 downward so that it is located at the bottom of the guide rail 721. Then, pass the rod 61 through the uppermost connection hole 3. The head 62 cannot pass through the connection hole 3. Then, pull the wedge piece 5 in the wedge to be assembled upward to the top. Press the two pressure pads 4 with your fingers to compress the spring 43, reducing the width of the entire wedge.

[0076] Step 2: Feed the wedge upward from the bottom of the main slot 64 and move the wedge horizontally so that one of the pressure pads 4 enters the interior of the limit frame 11;

[0077] Step 3: Release the pressure pad 4 pressed by the finger to allow the spring 43 to rebound, and pull the wedge-shaped piece 5 downward through the drag plate 52 to insert the protrusion 44 into the empty space provided in the sealing end. The empty space in this embodiment should be a hole-shaped structure provided in the sealing end;

[0078] Step 4: Use a hammer to hit the drag plate 52 so that the wedge-shaped piece 5 applies pressure to the pressure pads 4 on both sides, thereby fixing the connecting component 6 with the wedge;

[0079] Step 5: Rotate the limiting bracket 65 that can be inserted into the corresponding limiting hole 51 so that the limiting bracket 65 locks the height of the wedge 5 to prevent it from loosening;

[0080] Step 6: Push the retainer 10 upward so that the slope groove 101 has a pre-tightening pressure on the head 62, thereby improving the stability of the entire connecting component 6. When the retainer 10 is in place, the plug 93 is inserted into the socket 722, which can limit the downward movement of the retainer 10, thereby ensuring the stability of the retainer 10.

[0081] During disassembly, the following steps are involved:

[0082] Step 1: Manually pull the moving block 91 to compress the second spring 92, disengage the plug 93 from the socket 722, and push the retainer 10 downward to disengage the retainer 10 downward from the connecting component 6;

[0083] Step 2: Reversely rotate the limiting arc frame 65 to disengage it from the limiting hole 51, then hammer the drag plate 52 upward to move the drag plate 52 upward, thereby reducing the distance between the two pressure pads 4 and causing the protrusion 44 to disengage from the first curved rail 611. Pull the wedge downward as a whole to disengage from the main groove 64.
