Description

Technical Field

[0001] This invention relates to the field of cable fixing technology, and more specifically to fixing devices. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. Cables have many uses, mainly for control installation, equipment connection, and power transmission. They are a common and indispensable item in daily life. In some residential water and electricity construction processes, cable fixing devices are used to clamp and fix the cables.

[0003] Currently, cable ties are commonly used to bundle cables for secure fastening. However, cable ties are not reusable, leading to higher material costs. Furthermore, cable ties often fail to secure cables properly, as they rely primarily on friction to hold the cables in place, making them prone to loosening under prolonged use or vibration, resulting in cable displacement or detachment. Additionally, once secured, traditional cable ties are difficult to adjust or remove, making secondary installations and maintenance inconvenient. Moreover, cable ties have poor adaptability to curved or irregular surfaces; if too tight, they may crush the cable sheath; if too loose, the cable may slip or wear. Summary of the Invention

[0004] This invention provides a fixing device to solve the problems of high material cost, unstable fixing, difficulty in adjustment, and poor adaptability to curved or irregular surfaces caused by using cable ties to fix cables.

[0005] In a first aspect, the present invention provides a fixing device, comprising: The mounting structure has a mounting cavity with two first openings at both ends, the two first openings being arranged opposite to each other, and the mounting structure is suitable for installation at the mounting position; At least two fixing structures, each of the fixing structures including a fixing component and a locking component, the fixing component having a fixing cavity with second openings at both ends, the locking component being disposed at one of the second openings of the fixing component, one end of the fixing component having the locking component being adapted to be inserted into the mounting cavity through the first opening to connect with the mounting structure, and communicating the fixing cavity and the mounting cavity through the second opening, the locking component being adapted to fix the cable; The cable is adapted to be inserted into the fixing cavity and the mounting cavity through the second opening of one of the fixing components, and to extend out through the second opening of the other fixing component.

[0006] Beneficial effects: By using two fixing structures connected to the mounting structure, when the mounting structure is installed in the mounting position, the cable can pass through the second opening of one fixing component into the fixing cavity and the mounting cavity, and pass through the second opening of the other fixing component out of the fixing cavity and the mounting cavity. This allows the locking component located in the mounting cavity to fix the cable in the fixing cavity and the mounting cavity. In this way, the problems of high material cost, weak fixation, difficulty in adjustment, and poor adaptability to curved or irregular surfaces caused by using cable ties to fix cables can be avoided. This helps to improve the fixing strength of cables and the adaptability to cables with curved or irregular surfaces, and reduces the cost and adjustment difficulty of fixing cables.

[0007] In one alternative embodiment, the locking assembly includes a clamping head, a fastening sleeve, and a locking housing. The clamping head is disposed at one of the second openings of the fixing assembly, the fastening sleeve is disposed within the locking housing, and the locking housing is adapted to connect with the clamping head to press the clamping head by the fastening sleeve and to secure the cable by the clamping head.

[0008] Beneficial effects: By setting the locking assembly including a clamping head, a fastening sleeve, and a locking housing, wherein the clamping head is located at one of the second openings of the fixing assembly, the fastening sleeve is located inside the locking housing, and the locking housing can be connected to the clamping head, specifically through a threaded connection, so that when the end of the fixing assembly with the locking assembly is inserted into the mounting cavity through the first opening, the clamping head, fastening sleeve, and locking housing can simultaneously enter the mounting cavity; in addition, when the locking housing is connected to the clamping head, the fastening sleeve will press the clamping head, so that when the locking housing and the clamping head are tightened, the clamping head can fix the cable, and when the locking housing and the clamping head are loosened, the fastening sleeve will separate from the clamping head, at which point the clamping head can no longer clamp the cable, allowing the cable to move on the clamping head. In this way, cable adjustment can be easily achieved.

[0009] In one optional embodiment, the clamping head includes a body and a plurality of clamping parts, all of which are disposed on the same side of the body, and one end of each clamping part is connected to the body, while the other end is disposed close to the axis of the body.

[0010] Beneficial effects: By setting the clamping head to include a body and several clamping parts, the clamping parts in this embodiment are clamping rods. All the clamping parts are located on the same side of the body, specifically the side of the clamping head away from the fixing component. One end of each clamping part is connected to the body, and the other end is located close to the axis of the body. Thus, when the fastening sleeve abuts against the clamping part, the fastening sleeve can press all the clamping parts together, causing the ends of all the clamping parts away from the body to move toward the axis of the body. In this way, the cable can be clamped and fixed by the ends of all the clamping parts away from the body. It should be noted that the fixing strength of this fixing method will not change if the locking housing and the clamping head do not shift.

[0011] In one alternative embodiment, the locking housing has a threaded state in which it is connected to the clamping head portion to separate the fastening sleeve from the clamping portion, and a fixed state in which it is fully connected to the clamping head to abut the fastening sleeve against the clamping portion.

[0012] Beneficial effects: By setting the locking housing to have a fastening state and a cable threading state, the cable threading state is such that the locking housing is connected to the clamping head so that the fastening sleeve is separated from the clamping part, thereby dispersing all the clamping parts of the clamping head away from the body, thus allowing the cable to be threaded normally; while in the locking state, the locking housing is fully connected to the clamping head so that the fastening sleeve abuts against the clamping part, thereby bringing all the clamping parts of the clamping head away from the body closer together, so that all the clamping parts away from the body can simultaneously abut against the cable and fix the cable.

[0013] In one optional embodiment, the fixing component includes a corrugated outer tube and a corrugated inner tube, the corrugated outer tube being sleeved on the corrugated inner tube, two second openings being respectively opened at both ends of the corrugated inner tube, and the corrugated inner tube having the fixing cavity.

[0014] Beneficial effects: By setting a fixing component including a corrugated outer tube and a corrugated inner tube, wherein the corrugated outer tube is sleeved on the corrugated inner tube, and two second openings are respectively opened at both ends of the corrugated inner tube, and the fixing cavity is also opened on the corrugated inner tube, it can be ensured that the cable can be inserted through the second opening.

[0015] In one alternative embodiment, along the axial direction of the fixing component, a first connecting portion is provided on the side wall of the corrugated outer tube, and a second connecting portion is provided on the side wall of the corrugated inner tube. The corrugated inner tube has an observation state in which it rotates relative to the corrugated outer tube under the action of an external force to make the second connecting portion coincide with the first connecting portion, and a blocking state in which the second connecting portion is misaligned with the first connecting portion.

[0016] Beneficial effects: Through the first connecting portion on the corrugated outer tube and the second connecting portion on the corrugated inner tube, which in this embodiment are the first connecting hole and the second connecting hole respectively, the first connecting portion and the second connecting portion are both opened on the corrugated outer tube and the corrugated inner tube along the axial direction of the fixing component. Thus, when the corrugated inner tube rotates relative to the corrugated outer tube under the action of external force, the corrugated inner tube can have an observation state in which the second connecting portion coincides with the first connecting portion and a blocking state in which the second connecting portion is misaligned with the first connecting portion. In the observation state, the staff can observe the condition of the cable in the fixing cavity through the first connecting portion and the second connecting portion to avoid damage to the cable. In the blocking state, the corrugated inner tube and the corrugated outer tube can block the first connecting portion and the second connecting portion at the same time to prevent the cable from leaking out of the fixing cavity and being damaged by the outside.

[0017] In one optional embodiment, the mounting structure includes a first sleeve, a second sleeve, and a connecting assembly, wherein the first sleeve and the second sleeve are adapted to be connected by the connecting assembly, and when connected, the first sleeve and the second sleeve together form the mounting cavity.

[0018] Beneficial effects: The installation structure includes a first sleeve, a second sleeve, and a connecting component. The first sleeve and the second sleeve can be connected by the connecting component. When connected, the first sleeve and the second sleeve can form an installation cavity together. When separated, the operator can adjust the tightness between the locking housing and the clamping head according to the construction situation. After adjustment, the first sleeve and the second sleeve are connected together by the connecting component.

[0019] In one optional embodiment, the connecting assembly includes a first connecting seat, a second connecting seat, and a connecting unit. The first connecting seat is formed on the first sleeve, the second connecting seat is formed on the second sleeve, and the connecting unit is disposed between the first connecting seat and the second connecting seat to connect the first connecting seat and the second connecting seat.

[0020] Beneficial effects: By setting the connecting component including a first connecting seat, a second connecting seat and a connecting unit, wherein the first connecting seat is formed on the first sleeve, the second connecting seat is formed on the second sleeve, and the connecting unit is disposed between the first connecting seat and the second connecting seat, thereby connecting the first connecting seat and the second connecting seat together, and further connecting the first sleeve and the second sleeve together.

[0021] In one optional embodiment, the second connecting seat has a connecting portion, and a locking block is provided in the connecting portion; the connecting unit includes a buckle and a biasing member, the biasing member is sleeved on the buckle, and the buckle is movably disposed on the first connecting seat; Under the action of external force, the buckle is adapted to be inserted into the connecting part and connected to the card block to connect the first connecting seat and the second connecting seat.

[0022] Beneficial effects: Through the connecting part opened on the second connecting seat, the locking block disposed in the connecting part, and the connecting unit including the buckle and the biasing member, the connecting part in this embodiment is a connecting hole, and the biasing member in this embodiment is a spring. The biasing member is sleeved on the buckle, and the buckle is movably disposed on the first connecting seat. Thus, under the action of external force, the buckle can be inserted into the connecting part and connected with the locking block, thereby connecting the first connecting seat and the second connecting seat together.

[0023] In one optional embodiment, the first connector is provided with a blocking part, and when the buckle is inserted into the connector, the buckle is adapted to abut against the blocking part to limit the buckle by the blocking part; the second connector is also provided with a transition part, and the second connector is adapted to be installed to the installation position by the transition part.

[0024] Beneficial effects: By providing a blocking part (in this embodiment, the blocking part is a blocking block) on the first connecting seat, when the buckle is inserted into the connecting part, the buckle can abut against the blocking part, thereby limiting the buckle and preventing the buckle from being bounced off by the elastic force provided by the biasing member due to the buckle and the buckle block not being properly connected; and by providing an adapter part (in this embodiment, the adapter hole) on the second connecting seat, the second connecting seat can be installed to the installation position through the adapter part.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, in one aspect, a fixing device is provided, such as... Figures 1 to 7 As shown, the device includes an installation structure 1 and two fixing structures 2. The installation structure 1 has an installation cavity with two openings at both ends, and the two openings are arranged opposite to each other. The installation structure 1 is suitable for installation at the installation position. Each fixing structure 2 includes a fixing component 21 and a locking component 22. The fixing component 21 has a fixing cavity with two openings at both ends, and the locking component 22 is disposed at one of the second openings of the fixing component 21. One end of the fixing component 21 with the locking component 22 is adapted to be inserted into the installation cavity through the first opening to connect with the installation structure 1, and communicates with the fixing cavity and the installation cavity through the second opening. The locking component 22 is suitable for fixing a cable. The cable is adapted to be inserted into the fixing cavity and the installation cavity through the second opening of one fixing component 21, and extends out through the second opening of the other fixing component 21.

[0031] The fixing device described above uses two fixing structures 2 connected to the mounting structure 1. The mounting structure 1 can be installed at the mounting position and has a mounting cavity with two first openings at both ends, which are arranged opposite each other. Each fixing structure 2 includes a fixing component 21 and a locking component 22. The fixing component 21 has a fixing cavity with two second openings at both ends, and the locking component 22 is located at one of the second openings of the fixing component 21. The end of the fixing component 21 with the locking component 22 can be inserted into the mounting cavity through the first opening, thereby connecting the fixing component 21 and the mounting structure 1 together. The fixing cavity and the mounting cavity can be connected through the second opening of the fixing component 21. After the two fixing components 21 are respectively connected to one of the first openings of the mounting structure 1, the mounting cavity can be made open at both ends through the second opening of the fixing cavity. The locking component 22 can fix the cable. Thus, when the end of the cable passes through the second opening and exits the fixing cavity and the mounting cavity, the locking component 22 can fix the cable in the fixing cavity and the mounting cavity.

[0032] It should be noted that the installation location in this embodiment is a pre-drilled mounting hole on a wall, desktop, or other structure. Any structure with a mounting hole can accommodate the fixing device provided in this embodiment.

[0033] Specifically, the method of using the fixing device is as follows: first, install the mounting structure 1 at the installation position; then, insert the end of the cable into and out of the fixing cavity and the mounting cavity; finally, fix the cable with the locking component 22. Using the fixing device provided in this embodiment, since the fixing device can be removed from the installation position, it can be reused, avoiding the problem of excessive material costs; at the same time, the cable is fixed in the fixing cavity and the mounting cavity by the locking component 22, which can improve the fixing firmness of the cable and the adaptability to cables with curved or irregular surfaces; in addition, since the locking component 22 does not interfere with the cable's passage when it enters and exits the fixing cavity and the mounting cavity, the difficulty of cable adjustment can be reduced.

[0034] In summary, by using two fixing structures 2 connected to the mounting structure 1, when the mounting structure 1 is installed in the mounting position, the cable can pass through the second opening of one fixing component 21 into the fixing cavity and the mounting cavity, and pass through the second opening of the other fixing component 21 out of the fixing cavity and the mounting cavity. This allows the locking component 22, which is located in the mounting cavity, to fix the cable in the fixing cavity and the mounting cavity. In this way, the problems of high material cost, weak fixation, difficulty in adjustment, and poor adaptability to curved or irregular surfaces caused by using cable ties to fix the cable can be avoided. This is beneficial to improving the fixing strength of the cable and the adaptability to cables with curved or irregular surfaces, and reducing the cost and adjustment difficulty of fixing the cable.

[0035] In one embodiment, such as Figure 2 and Figure 3 As shown, the locking assembly 22 includes a clamping head 221, a fastening sleeve 222, and a locking housing 223. The clamping head 221 is disposed at one of the second openings of the fixing assembly 21, and the fastening sleeve 222 is disposed inside the locking housing 223. The locking housing 223 is adapted to connect with the clamping head 221 to press the clamping head 221 with the fastening sleeve 222 and to fix the cable with the clamping head 221.

[0036] The aforementioned fixing device, by providing a locking assembly 22 including a clamping head 221, a fastening sleeve 222, and a locking housing 223, wherein the clamping head 221 is disposed at one of the second openings of the fixing assembly 21, the fastening sleeve 222 is disposed within the locking housing 223, and the locking housing 223 can be connected to the clamping head 221, specifically through a threaded connection, so that when the end of the fixing assembly 21 with the locking assembly 22 is inserted into the mounting cavity through the first opening, the clamping head 221, the fastening sleeve 222, and the locking housing are engaged. 223 can enter the mounting cavity simultaneously; in addition, when the locking housing 223 is connected to the clamping head 221, the fastening sleeve 222 will press the clamping head 221, so that when the locking housing 223 and the clamping head 221 are tightened, the clamping head 221 can fix the cable, and when the locking housing 223 and the clamping head 221 are loosened, the fastening sleeve 222 will separate from the clamping head 221. At this time, the clamping head 221 can no longer clamp the cable, so that the cable can move on the clamping head 221. In this way, the cable can be easily adjusted.

[0037] In one embodiment, such as Figure 3 As shown, the clamping head 221 includes a body 2211 and a plurality of clamping parts 2212. All clamping parts 2212 are disposed on the same side of the body 2211, and one end of any clamping part 2212 is connected to the body 2211, while the other end is disposed close to the axis of the body 2211.

[0038] The fixing device described above includes a clamping head 221 comprising a body 2211 and several clamping parts 2212. In this embodiment, the clamping parts 2212 are clamping rods. All clamping parts are located on the same side of the body 2211, specifically on the side of the clamping head 221 away from the fixing component 21. One end of each clamping part 2212 is connected to the body 2211, and the other end is located close to the axis of the body 2211. Thus, when the fastening sleeve 222 abuts against the clamping parts 2212, the fastening sleeve 222 can press all the clamping parts 2212 together, causing the ends of all the clamping parts 2212 away from the body 2211 to move toward the axis of the body 2211. This allows the cable to be clamped and fixed through the ends of all the clamping parts 2212 away from the body 2211. It should be noted that the fixing strength of this fixing method will not change if the locking housing 223 and the clamping head 221 do not shift.

[0039] It should be noted that since the clamping head 221 fixes the cable by the contact between the ends of all clamping parts 2212 away from the body 2211 and the cable, when the clamping head 221 fixes the cable, whether the surface of the cable is curved or irregular will not affect the contact between the ends of the clamping parts 2212 and the surface of the cable. This makes the fixing device highly adaptable to fixing cables with curved or irregular surfaces.

[0040] In one embodiment, such as Figure 2 and Figure 3 As shown, the locking housing 223 has a threaded state in which it is partially connected to the clamping head 221 to separate the fastening sleeve 222 from the clamping part 2212, and a fixed state in which it is fully connected to the clamping head 221 to abut the fastening sleeve 222 against the clamping part 2212.

[0041] The fixing device described above has a locking housing 223 that has both a fastening state and a cable threading state. In the cable threading state, the locking housing 223 is partially connected to the clamping head 221, causing the fastening sleeve 222 to separate from the clamping part 2212. This disperses the ends of all the clamping parts 2212 of the clamping head 221 away from the body 2211, allowing the cable to be threaded normally. In the locking state, the locking housing 223 is fully connected to the clamping head 221, causing the fastening sleeve 222 to abut against the clamping part 2212. This brings the ends of all the clamping parts 2212 away from the body 2211 closer together, allowing all the ends of the clamping parts 2212 away from the body 2211 to simultaneously abut against the cable and fix it in place.

[0042] In one embodiment, such as Figure 3As shown, the fixing component 21 includes a corrugated outer tube 211 and a corrugated inner tube 212. The corrugated outer tube 211 is sleeved on the corrugated inner tube 212, and two second openings are respectively opened at both ends of the corrugated inner tube 212. The corrugated inner tube 212 has a fixing cavity.

[0043] The fixing device of the above structure includes a fixing component 21 comprising a corrugated outer tube 211 and a corrugated inner tube 212. The corrugated outer tube 211 is sleeved on the corrugated inner tube 212, and two second openings are respectively opened at both ends of the corrugated inner tube 212. The fixing cavity is also opened on the corrugated inner tube 212. In this way, the cable can be inserted through the second opening.

[0044] In one embodiment, such as Figure 3 As shown, along the axial direction of the fixing component 21, a first connecting portion 2111 is provided on the side wall of the corrugated outer tube 211, and a second connecting portion 2121 is provided on the side wall of the corrugated inner tube 212. The corrugated inner tube 212 has an observation state in which it rotates relative to the corrugated outer tube 211 under the action of external force, so that the second connecting portion 2121 coincides with the first connecting portion 2111, and a blocking state in which the second connecting portion 2121 is misaligned with the first connecting portion 2111.

[0045] The fixing device described above utilizes a first connecting portion 2111 on the corrugated outer tube 211 and a second connecting portion 2121 on the corrugated inner tube 212. In this embodiment, the first connecting portion 2111 and the second connecting portion 2121 are respectively a first connecting hole and a second connecting hole. Both the first connecting portion 2111 and the second connecting portion 2121 are located along the axial direction of the fixing assembly 21 on the corrugated outer tube 211 and the corrugated inner tube 212, respectively. Therefore, when the corrugated inner tube 212 rotates relative to the corrugated outer tube 211 under external force, the corrugated inner tube 212... The device 12 can have an observation state where the second connecting portion 2121 coincides with the first connecting portion 2111, and a blocking state where the second connecting portion 2121 is misaligned with the first connecting portion 2111. In the observation state, the operator can observe the cable inside the fixing cavity through the first connecting portion 2111 and the second connecting portion 2121 to prevent cable damage. In the blocking state, the corrugated inner tube 212 and the corrugated outer tube 211 can simultaneously block the first connecting portion 2111 and the second connecting portion 2121 to prevent the cable from leaking out of the fixing cavity and being damaged by the outside. It should be noted that the external force in this embodiment is the human effort provided by the operator.

[0046] In one embodiment, such as Figure 4 and Figure 5 As shown, the mounting structure 1 includes a first sleeve 11, a second sleeve 12, and a connecting assembly 13. The first sleeve 11 and the second sleeve 12 are adapted to be connected by the connecting assembly 13. When connected, the first sleeve 11 and the second sleeve 12 together form a mounting cavity.

[0047] The fixing device of the above structure includes a first sleeve 11, a second sleeve 12 and a connecting component 13 in the installation structure 1. The first sleeve 11 and the second sleeve 12 can be connected by the connecting component 13. When connected, the first sleeve 11 and the second sleeve 12 can form an installation cavity together. When separated, the operator can adjust the tightness between the locking housing 223 and the clamping head 221 according to the construction situation. After adjustment, the first sleeve 11 and the second sleeve 12 are connected together by the connecting component 13.

[0048] In one embodiment, such as Figure 4 and Figure 5 As shown, the connecting assembly 13 includes a first connecting seat 131, a second connecting seat 132, and a connecting unit 133. The first connecting seat 131 is formed on the first sleeve 11, the second connecting seat 132 is formed on the second sleeve 12, and the connecting unit 133 is disposed between the first connecting seat 131 and the second connecting seat 132 to connect the first connecting seat 131 and the second connecting seat 132.

[0049] The fixing device with the above structure includes a first connecting seat 131, a second connecting seat 132, and a connecting unit 133 by setting a connecting component 13. The first connecting seat 131 is formed on the first sleeve 11, the second connecting seat 132 is formed on the second sleeve 12, and the connecting unit 133 is disposed between the first connecting seat 131 and the second connecting seat 132, thereby connecting the first connecting seat 131 and the second connecting seat 132 together, and further connecting the first sleeve 11 and the second sleeve 12 together.

[0050] In one embodiment, such as Figure 5 and Figure 6 As shown, the second connecting seat 132 has a connecting part 1321, and a locking block is provided in the connecting part 1321; the connecting unit 133 includes a buckle 1331 and a biasing member 1332, the biasing member 1332 is sleeved on the buckle 1331, and the buckle 1331 is movably disposed on the first connecting seat 131; under the action of external force, the buckle 1331 is adapted to be inserted into the connecting part 1321 and connected with the locking block to connect the first connecting seat 131 and the second connecting seat 132.

[0051] The fixing device described above comprises a connecting portion 1321 on the second connecting seat 132, a locking block disposed within the connecting portion 1321, and a fastener 1331 and a biasing member 1332 disposed in the connecting unit 133. In this embodiment, the connecting portion 1321 is a connecting hole, and the biasing member 1332 is a spring. The biasing member 1332 is sleeved on the fastener 1331, which is movably disposed on the first connecting seat 131. Thus, under external force, the fastener 1331 can be inserted into the connecting portion 1321 and connected to the locking block, thereby connecting the first connecting seat 131 and the second connecting seat 132 together. It should be noted that in this embodiment, the external force is the human force provided by the worker.

[0052] Specifically, the cross-sectional dimension of the connecting part 1321 is larger than that of the buckle 1331. Therefore, when the buckle 1331 is inserted into the connecting part 1321, the buckle 1331 can move laterally in the connecting part 1321, thereby enabling the buckle 1331 to connect with the block. Due to the presence of the biasing member 1332, it will accumulate elastic force when the buckle 1331 is inserted into the connecting part 1321. Therefore, after the buckle 1331 is connected with the block, the biasing member 1332 will use the elastic force to drive the buckle 1331 out of the connecting part 1321, but the buckle 1331 will be connected to the block again, so that the connection strength between the buckle 1331 and the block is improved due to the presence of the elastic force.

[0053] In one embodiment, such as Figure 5 and Figure 7 As shown, the first connecting seat 131 is provided with a blocking part 1311. When the buckle 1331 is inserted into the connecting part 1321, the buckle 1331 is adapted to abut against the blocking part 1311 so as to limit the buckle 1331 by the blocking part 1311. The second connecting seat 132 is also provided with a transition part 1322. The second connecting seat 132 is adapted to be installed to the installation position by the transition part 1322.

[0054] The fixing device of the above structure has a blocking part 1311 provided on the first connecting seat 131. In this embodiment, the blocking part 1311 is a blocking block. When the buckle 1331 is inserted into the connecting part 1321, the buckle 1331 can abut against the blocking part 1311, thereby limiting the buckle 1331 by the blocking part 1311. This can prevent the buckle 1331 from being bounced off by the elastic force provided by the biasing member 1332 due to the buckle 1331 not being properly connected to the buckle block. The adapter part 1322 provided on the second connecting seat 132, which is an adapter hole in this embodiment, allows the second connecting seat 132 to be installed in the installation position through the adapter part 1322.

[0055] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
