[0004] In the related art, the fixing method of the floating nut is complicated, which makes the installation efficiency of the computing node low. Utility Model Content

[0005] The embodiment of the present application provides a floating nut and a whole cabinet server, and the fixing method of the floating nut is simple, thereby improving the installation efficiency of the computing node.

[0006] In the first aspect, an embodiment of the present application provides a floating nut, comprising: a nut body and a containing shell, the nut body is located in the containing shell, the nut body comprises a main body portion and a magnetic portion, the magnetic portion is used to make the floating nut adsorbed on the first surface of the mounting plate so that the floating nut is fixed on the mounting plate; the main body portion is used to fix the computing node to the second surface of the mounting plate, the second surface and the first surface are opposite along a first direction.

[0007] The floating nut provided in the embodiment of the present application is provided with a nut body and a containing shell, wherein the nut body is located in the containing shell, and the nut body includes a main body portion and a magnetic portion, wherein the magnetic portion is used to make the floating nut adsorbed on the first surface of the mounting plate so that the floating nut is fixed on the mounting plate, and the fixing method of the floating nut is simple, so that the installation efficiency of the computing node is relatively high. The main body portion fixes the hanging ear to the mounting plate through fasteners and floating nuts to fix the computing node on the cabinet, and the second surface and the first surface are opposite to each other along a first direction. When it is necessary to move the position of the floating nut, the operator only needs to move the floating nut on the first surface of the mounting plate to align with the second mounting hole of the hanging ear and the first mounting hole on the mounting plate. The movement process of the floating nut position does not interfere with the computing node on the second surface, so there is no need to move the computing node on the second surface again, which can further improve the installation efficiency of the computing node.

[0008] In a possible implementation, the floating nut provided in the embodiment of the present application has a body portion and a magnetic portion arranged along a first direction, and the body portion is arranged close to the first surface. The body portion is located between the mounting plate and the magnetic portion, and when the fastener is screwed into the threaded hole to connect with the floating nut, the magnetic portion can be prevented from being subjected to force.

[0009] In a possible implementation, the floating nut provided in the embodiment of the present application has a threaded hole on the body portion, a first through hole on the magnetic portion, and the threaded hole and the first through hole are aligned along a first direction. By providing the first through hole on the magnetic portion, the volume of the magnetic portion can be increased as much as possible without affecting the installation of the fastener and the floating nut, so as to increase the magnetic attraction of the magnetic portion as much as possible.

In addition, the magnetic part and the main body are arranged along the second direction in the containing shell, and it is also possible to avoid the magnetic part occupying the space in the containing shell along the first direction, so that the size of the main body along the first direction is larger. As a result, the size of the threaded hole in the main body along the first direction is larger, so that the size of the threaded connection between the fastener and the nut body is larger, which can increase the connection strength between the fastener and the floating nut.

[0011] In a possible implementation, the floating nut provided in the embodiment of the present application has the magnetic parts located on both sides of the body part along the second direction, thereby maintaining force balance on the floating nut along the second direction and preventing one end of the floating nut from tilting when adsorbed on the mounting plate.

[0012] In a possible implementation, in the floating nut provided in the embodiment of the present application, the edge of the magnetic part is spaced a first distance from the edge of the body part.

The bent portion can be shielded on the side of the nut body away from the bottom wall, thereby preventing the nut body from falling out of the housing cavity.

[0014] In a possible implementation, the floating nut provided in the embodiment of the present application, the housing further comprises a clamping portion, the clamping portion extends from the bent portion along the first direction, and the clamping portion is used to be inserted into the mounting plate. When the fastener is screwed into the floating nut, the clamping portion can abut against the side of the first mounting hole to prevent the floating nut from rotating as the fastener rotates.

[0071] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0072] Figure 1 A schematic diagram of the structure of a data center provided in an embodiment of the present application.

[0073] See also Figure 1 As shown, the data center 1000 is a facility for installing computing equipment and related components, such as telecommunications and storage systems. The data center 1000 provided in the embodiment of the present application may include a computer room 20 and at least one computing device arranged in the computer room 20. It is understood that the computer room 20 may be a closed room or a room with one or more sides open; the computer room 20 may be a temporary room, such as a tent room, a board room, etc., or a permanent room.

[0074] Only one computing device or multiple computing devices may be arranged in the computer room 20. When multiple computing devices are arranged in the computer room 20, each computing device may be the same, partially the same, or completely different. The computing device may be a desktop server, a blade server, a rack server, a high-density server, a whole cabinet server, or other types.

[0075] Whole cabinet servers are widely used in cloud computing, high performance computing (HPC), big data, artificial intelligence and other fields due to their high space utilization.

[0076] The structure of the computing device is described below by taking the whole cabinet server 10 as an example.

[0077] Figure 2 A schematic diagram of the structure of a whole cabinet server provided in an embodiment of the present application.

[0078] See also Figure 2 As shown, the whole cabinet server 10 includes a cabinet 100 and a plurality of computing nodes 200 installed in the cabinet 100, and the cabinet 100 serves as a supporting component of the computing nodes 200. For details, please continue to refer to Figure 2 As shown, the cabinet 100 includes a length direction X, a width direction Y and a height direction Z, and a plurality of computing nodes 200 are sequentially arranged in the cabinet 100 at intervals along the height direction Z.

[0079] Next, the installation method of the computing node 200 in the cabinet 100 is described.

[0080] Figure 3 A schematic diagram of the structure of a cabinet in a whole cabinet server provided in an embodiment of the present application; Figure 4A structural schematic diagram of the relative positions of the mounting plate and the computing nodes in the whole cabinet server provided in an embodiment of the present application; Figure 5 A schematic diagram of the structure of the mounting plate in the whole cabinet server provided in the embodiment of the present application; Figure 6 A schematic diagram of the structure of a computing node in a whole cabinet server provided in an embodiment of the present application; Figure 7 A schematic diagram of the structure of the mounting ears in the whole cabinet server provided in the embodiment of the present application; Figure 8 A schematic diagram of the installation method of the mounting ears and the mounting plate in the whole cabinet server provided in an embodiment of the present application.

[0081] See also Figures 3 to 8 As shown, the cabinet 100 includes a cabinet body 110, a mounting plate 120 and a slide rail 130, wherein the slide rail 130 extends in a width direction Y, is arranged in pairs in a length direction X and is arranged at intervals in a height direction Z. The mounting plate 120 is mounted on the cabinet body 110 and extends in a height direction Z. The mounting plate 120 has first mounting holes 121 arranged at intervals in the height direction Z of the cabinet 100, and the mounting plate 120 includes a first surface 120a and a second surface 120b opposite to each other in a first direction F1. In the embodiment of the present application, the first direction F1 is consistent with the width direction Y of the cabinet 100.

[0082] The computing node 200 includes a node housing 210 and a mounting ear 220. The mounting ear 220 is fixedly connected to the node housing 210. Figure 4 and Figure 6 In the illustrated embodiment, both ends of the node housing 210 along the length direction X are provided with hanging ears 220 .

[0083] Please continue to see Figure 7 As shown, the ear 220 can be a rectangular parallelepiped structure, and the ear 220 includes a bottom plate 221, a top wall 222 and four side walls 223, the four side walls 223 are respectively a first side wall 223a, a second side wall 223b, a third side wall 223c and a fourth side wall 223d, the first side wall 223a and the second side wall 223b are arranged opposite to each other along the length direction X, the third side wall 223c and the fourth side wall 223d are arranged opposite to each other along the width direction Y, and the bottom plate 221 and the top wall 222 are arranged opposite to each other along the height direction Z.

[0084] The fourth side wall 223d faces the second surface 120b of the mounting plate 120, and has a second mounting hole 2231 on the fourth side wall 223d. The third side wall 223c has an opening 2233 aligned with the second mounting hole 2231 along the width direction Y. Figure 7 In the figure, the second mounting hole 2231 is blocked, so the second mounting hole 2231 is shown in dotted lines. Figure 7As shown, various interfaces 2232 are also provided on the side wall 223 of the hanging ear 220, such as a USB (Universal Serial Bus) interface, a VGA (Video Graphics Array) or a network port, etc., so as to make full use of the space on the side wall 223 of the hanging ear 220. The interfaces 2232 on the two hanging ears 220 at both ends of the node housing 210 can be the same or different. The computing node 200 also includes a motherboard (not shown in the figure), which is located in the node housing 210. These interfaces 2232 can be electrically connected to the motherboard through leads.

[0085] When the computing node 200 is installed in the cabinet 100, the node housing 210 is placed on the slide rail 130, and the node housing 210 is pushed into the cabinet 100 along the width direction Y. The second mounting hole 2231 on the hanging ear 220 is aligned with the first mounting hole 121 on the mounting plate 120, and then the hanging ear 220 is installed on the cabinet 100 through the first mounting hole 121.

[0086] For details, please refer to Figure 8 As shown, the whole cabinet server 10 also includes a floating nut 300 and a fastener 400. The floating nut 300 is located on the first surface 120a of the mounting plate 120. The fastener 400 enters the hanging ear 220 from the opening 2233. The fastener 400 passes through the second mounting hole 2231 in the fourth side wall 223d of the hanging ear 220 and the first mounting hole 121 in the mounting plate 120 in sequence to be screwed into the floating nut 300. Thus, the computing node 200 can be connected to the cabinet 100 through the fastener 400 and the floating nut 300, wherein the screwing direction of the fastener 400 is also the first direction F1.

[0087] In the related art, the floating nut includes a nut body and buckles located at the upper and lower ends of the nut body. When installing the computing node, first, the buckle located at the lower end of the floating nut is snapped with the side wall of the first mounting hole on the mounting plate, and then the floating nut is tilted so that the floating nut passes through the first mounting hole from the second surface to the side of the first surface, and then the installation tool is passed through the first mounting hole and the installation tool is snapped with the buckle at the upper end of the floating nut; the operator presses down and pulls the installation tool toward the second surface, so that the buckle at the upper end of the floating nut passes through the first mounting hole from the first surface to the side of the second surface, and at this time, the buckle at the upper end of the nut is snapped with the mounting plate under the action of the installation tool; finally, the nut installation tool is loosened to complete the fixing of the floating nut. After installing the floating nut, the computing node shell is placed on the slide rail, and the computing node shell is pushed into the cabinet along the width direction, and then the fastener is used to pass through the ear and the first mounting hole on the mounting plate to fix the computing node on the mounting plate. It can be seen that the fixing method of the floating nut is complicated, which makes the installation efficiency of the computing node low.

[0088] In addition, when the first mounting hole for installing the floating nut is not the preset first mounting hole for installing the computing node, it is necessary to pull the computing node out of the cabinet first, remove the floating nut, move the floating nut to the preset first mounting hole for installing the computing node, and then install the computing node into the cabinet, which makes the installation efficiency of the computing node lower.

[0089] Based on this, an embodiment of the present application provides a floating nut and a whole cabinet server, and the fixing method of the floating nut is simple, thereby improving the installation efficiency of the computing node.

[0091] See also Figures 9 to 16 As shown, the floating nut 300 provided in the embodiment of the present application includes a nut body 310 and a containing shell 320. The nut body 310 is located in the containing shell 320. The nut body 310 includes a main body portion 311 and a magnetic portion 312. The magnetic portion 312 is used to make the floating nut 300 adsorbed on the first surface 120a of the mounting plate 120 so that the floating nut 300 is fixed on the mounting plate 120; the main body portion 311 is used to fix the computing node 200 to the second surface 120b of the mounting plate 120, and the first surface 120a and the second surface 120b are opposite to each other along the first direction F1.

[0092] Please continue to see Figures 9 to 12 , Fig.14 and Fig.15As shown, the containing shell 320 has a containing cavity 321, and the nut body 310 is located in the containing cavity 321. The spatial shape of the containing cavity 321 matches the outer contour of the nut body 310 to accommodate the nut body 310. The outer contour size of the nut body 310 is slightly smaller than the size of the containing cavity 321, so that the position of the nut body 310 can be fine-tuned within the range limited by the containing cavity 321.

[0093] The function of the nut body 310 being able to fine-tune its position within the range limited by the accommodating cavity 321 is as follows: when the fastener 400 is sequentially passed through the second mounting hole 2231 in the hanging ear 220 and the first mounting hole 121 in the mounting plate 120 and screwed into the floating nut 300, since the position of the nut body 310 in the accommodating shell 320 can be fine-adjusted, when the position of the second mounting hole 2231 or the first mounting hole 121 is slightly offset, the nut body 310 can move within the accommodating shell 320, so that the floating nut 300 can compensate for the slight offset of the position of the second mounting hole 2231 or the first mounting hole 121, so as to facilitate the installation of the computing node 200.

[0094] The nut body 310 includes a body portion 311 and a magnetic portion 312 . The body portion 311 has a first threaded hole 3111 .

[0095] The magnetic part 312 can be made of a magnetic material, for example, the magnetic part 312 can be made of a natural magnet or an artificial magnet. The mounting plate 120 is usually made of a magnetic conductive material, for example, the mounting plate 120 can be made of an iron alloy. The floating nut 300 can be adsorbed on the first surface 120a of the mounting plate 120 through the magnetic part 312.

[0096] The outer contour of the accommodating shell 320 is larger than the diameter of the first mounting hole 121 on the mounting plate 120 .

[0097] When installing the computing node 200, first place the floating nut 300 on the first surface 120a of the mounting plate 120, and align the first threaded hole 3111 in the floating nut 300 with the first mounting hole 121 of the mounting plate 120; the magnetic part 312 can adsorb the floating nut 300 on the mounting plate 120 around the first mounting hole 121, thereby fixing the floating nut 300 to the mounting plate 120.

[0098] Then, the computing node 200 is placed on the slide rail 130, and the node housing 210 is pushed into the cabinet 100 along the width direction Y. The second mounting hole 2231 on the hanging ear 220 is aligned with the first mounting hole 121 on the mounting plate 120 and the first threaded hole 3111 on the floating nut 300, and the fastener 400 is passed through the second mounting hole 2231 and the first mounting hole 121 in sequence via the second surface 120b to be screwed into the first threaded hole 3111, thereby, the hanging ear 220 can be fixed to the mounting plate 120 by the fastener 400 and the floating nut 300, thereby, the computing node 200 can be fixed to the cabinet 100.

[0099] By setting a magnetic part 312 in the floating nut 300, the floating nut 300 can be adsorbed on the first surface 120a of the mounting plate 120 through the magnetic attraction between the magnetic part 312 and the mounting plate 120. Compared with the related technology that requires snaps and installation tools to fix the floating nut, the fixing method of the floating nut 300 is simple, which makes the installation efficiency of the computing node 200 higher.

[0100] The mounting plate 120 is provided with a plurality of first mounting holes 121 arranged at intervals, and the spacing between these first mounting holes 121 is small, for example, the spacing between two adjacent first mounting holes 121 may be less than or equal to 10 mm, and the first mounting holes 121 are arranged relatively closely along the height direction Z. The height of the computing node 200 is different, and the height of the computing node 200 may be 1U (U is a unit of measurement indicating the height of an electronic device, which is the abbreviation of unit, 1U is equal to 44.45 mm, 2U is equal to 88.9 mm, and so on), 2U, or 3U, etc. The installation positions of the mounting ears 220 in different computing nodes 200 are also different, and the positions of the second mounting holes 2231 in different mounting ears 220 are also different. Therefore, the relatively close arrangement of the first mounting holes 121 along the height direction Z can make the first mounting holes 121 adaptable to different computing nodes 200.

[0101] In the related art, after fixing the floating nut and pushing the computing node into the cabinet, it is found that the position of the floating nut is not aligned with the second mounting hole of the hanging ear and the first mounting hole on the mounting plate. It is necessary to first pull the computing node out of the cabinet, and then use the installation tool to remove the floating nut, and then use the installation tool to install the floating nut into another first mounting hole. The installation process of the computing node is complicated, which makes the installation efficiency of the computing node low.

[0102] In the embodiment of the present application, the operator only needs to move the floating nut 300 on the first surface 120a of the mounting plate 120 to align with the second mounting hole 2231 of the hanging ear 220 and the first mounting hole 121 on the mounting plate 120. The movement of the position of the floating nut 300 does not interfere with the computing node 200 on the second surface 120b, so there is no need to move the computing node 200 on the second surface 120b again, which can further improve the installation efficiency of the computing node 200.

[0103] The floating nut 300 provided in the embodiment of the present application is provided with a nut body 310 and a housing shell 320, wherein the nut body 310 is located in the housing shell 320, and the nut body 310 includes a body portion 311 and a magnetic portion 312, wherein the magnetic portion 312 is used to make the floating nut 300 adsorbed on the first surface 120a of the mounting plate 120, so that the floating nut 300 is fixed on the mounting plate 120, and the fixing method of the floating nut 300 is simple, so that the installation efficiency of the computing node 200 is high. The body portion 311 fixes the hanging ear 220 to the mounting plate 120 through the fastener 400 and the floating nut 300, so as to fix the computing node 200 on the cabinet 100, and the first surface 120a and the second surface 120b are opposite along the first direction F1. When it is necessary to move the position of the floating nut 300, the operator only needs to move the floating nut 300 on the first surface 120a of the mounting plate 120 to align with the second mounting hole 2231 of the hanging ear 220 and the first mounting hole 121 on the mounting plate 120. The movement of the position of the floating nut 300 does not interfere with the computing node 200 on the second surface 120b, so there is no need to move the computing node 200 on the second surface 120b again, which can further improve the installation efficiency of the computing node 200.

[0104] Next, the specific structures of the main body portion 311 and the magnetic portion 312 in the nut body 310 are described.

[0105] Please continue to see Figures 9 to 13 As shown, the body portion 311 and the magnetic portion 312 are arranged along the first direction F1 , and the body portion 311 is disposed close to the first surface 120 a .

[0106] Since the hardness of the magnetic part 312 is relatively low, the magnetic part 312 is at risk of breaking when subjected to force. Fig. 9 , Fig.10 and Fig.13 In the illustrated embodiment, the main body 311 is close to the first surface 120a and is located between the mounting plate 120 and the magnetic portion 312 . When the fastener 400 is screwed into the threaded hole 3111 to connect with the floating nut 300 , the magnetic portion 312 can be prevented from being subjected to force.

[0107] exist Fig.11In the illustrated embodiment, the magnetic portion 312 is two rectangular parallelepiped magnetic sheets disposed on the main body portion 311 .

[0108] exist Fig.12 In the illustrated embodiment, the magnetic portion 312 is a rectangular parallelepiped disposed on the main body portion 311 and having outer dimensions close to those of the main body portion 311. Thus, within the limited accommodation space of the accommodation shell 320, the volume of the magnetic portion 312 can be increased as much as possible to increase the magnetic attraction of the magnetic portion 312, thereby further increasing the reliability of the pre-fixation of the floating nut 300 and the mounting plate 120.

[0109] Therefore, it is necessary to set a first through hole 3121 on the magnetic part 312 , and the body part 311 has a threaded hole 3111 , and the threaded hole 3111 and the first through hole 3121 are aligned along the first direction F1 .

[0110] The fastener 400 passes through the second mounting hole 2231, the first mounting hole 121 and the first through hole 3121 in sequence and is screwed into the threaded hole 3111. By providing the first through hole 3121 on the magnetic part 312, the volume of the magnetic part 312 can be increased as much as possible without affecting the installation of the fastener 400 and the floating nut 300, so as to increase the magnetic attraction of the magnetic part 312 as much as possible. It should be noted that, since the end of the fastener 400 may exceed the first through hole 3121, the housing shell 320 also has a second through hole 322 so that the end of the fastener 400 passes through the second through hole 322.

[0111] Please continue to see Figures 14 to 16 As shown, the magnetic portion 312 and the body portion 311 are arranged along a second direction F2 , wherein the second direction F2 is perpendicular to the first direction F1 .

[0112] The second direction F2 may be consistent with the length direction X of the cabinet 100, or may be consistent with the height direction Z of the cabinet 100. Figures 14 to 16 In the illustrated embodiment, the second direction F2 is consistent with the length direction X of the cabinet 100 .

[0113] The magnetic part 312 and the main body part 311 are arranged along the second direction F2, so that the magnetic part 312 can avoid the fastener 400, thereby not hindering the fastener 400 from being screwed into the threaded hole 3111 of the main body part 311. In addition, the magnetic part 312 and the main body part 311 are arranged along the second direction F2 in the accommodating shell 320, and it is also possible to avoid the magnetic part 312 occupying the space in the accommodating shell 320 along the first direction F1, so that the size of the main body part 311 along the first direction F1 is larger. Therefore, the size of the threaded hole 311 in the main body part 311 along the first direction is larger, so that the size of the threaded connection between the fastener 400 and the nut body 310 is larger, which can increase the connection strength between the fastener 400 and the floating nut 300.

[0114] exist Fig.14 and Fig.15 In the illustrated embodiment, the magnetic portions 312 are located on both sides of the body portion 311 along the second direction F2 .

[0115] The magnetic part 312 can be two magnetic sheets arranged on both sides of the main body 311 along the second direction F2. Arranging two magnetic sheets on both sides of the main body 311 along the second direction F2 can keep the floating nut 300 under force balance along the second direction F2 and prevent one end of the floating nut 300 from tilting up when it is adsorbed on the mounting plate 120.

[0116] Fig.17 A schematic structural diagram of the magnetic portion and the main body portion of the floating nut provided in an embodiment of the present application.

[0117] See also Fig.17 As shown, the edge of the magnetic portion 312 has a first distance D1 from the edge of the body portion 312 .

[0118] Specifically, the dimension of the magnetic portion 312 along the first direction F1 is the magnetic portion thickness T1, and the dimension of the main body portion 311 along the first direction F1 is the main body thickness T2. Fig.17 The figure also shows the length L1 of the magnetic part and the length L2 of the body part. The thickness T1 of the magnetic part is smaller than the thickness T2 of the body part, and the length L1 of the magnetic part is smaller than the length L2 of the body part, so that the projection of the magnetic part 312 on the body part 311 is located inside the body part 311. When the fastener 400 is screwed into the threaded hole 3111 of the body part 311, the projection of the magnetic part 312 on the body part 311 is located inside the body part 311, so that the magnetic part 312 can be prevented from being damaged due to pressure.

[0119] In the embodiment of the present application, the main body portion 311 and the magnetic portion 312 are magnetically attracted or bonded.

[0120] The main body 311 may be made of a magnetic material, for example, the main body 311 may be made of an iron alloy. When the main body 311 is made of a magnetic material, the magnetic part 312 can be adsorbed on the main body 311 by magnetic attraction.

[0121] The main body 311 may also be made of a non-magnetic material. When the main body 311 is made of a non-magnetic material, the magnetic part 312 and the main body 311 may be bonded together by an adhesive. The main body 311 and the magnetic part 312 are connected by magnetic attraction or bonding, so that the connection method of the main body 311 and the magnetic part 312 is simple and the connection cost is low.

[0122] Next, the specific structure of the housing case 320 will be described.

[0123] Please continue to see Figures 9 to 16As shown, the accommodating shell 320 includes a bottom wall 323 and a limiting arm 324, the limiting arm 324 extends from the edge of the bottom wall 323 along the first direction F1, and the end of the limiting arm 324 facing away from the bottom wall 323 has a bending portion 325, and the projection of the bending portion 325 in the first direction F1 is located in the projection of the nut body 310 in the first direction F1.

[0124] Specifically, the bottom wall 323 and the limiting arm 324 extending from the edge of the bottom wall 323 form an accommodating cavity 321 , and the nut body 310 is located in the accommodating cavity 321 .

[0125] In order to prevent the nut body 310 from escaping from the accommodating cavity 321, a bending portion 325 can be provided at the end of the limiting arm 324 away from the bottom wall 323, and the bending portion 325 is bent toward the nut body 310. Thus, the bending portion 325 can cover the side of the nut body 310 away from the bottom wall 323, thereby preventing the nut body 310 from escaping from the accommodating cavity 321.

[0126] Please continue to see Figures 10 to 16 As shown, the accommodating shell 320 further includes a clamping portion 326 , which extends from the bending portion 325 along the first direction F1 , and is used to be inserted into the mounting plate 120 .

[0127] A clamping portion 326 may be provided at the end of each bending portion 325. Figures 10 to 16 In the embodiment shown, the two bent portions 325 are provided with a clamping portion 326. When the floating nut 300 is adsorbed on the first surface 120a of the mounting plate 120, the clamping portion 326 penetrates into the first mounting hole 121. When the fastener 400 is screwed into the floating nut 300, the clamping portion 326 can abut against the side of the first mounting hole 121 to prevent the floating nut 300 from rotating with the rotation of the fastener 400. Fig.12 and Fig.15 As shown, the dimension of the clamping portion 326 along the second direction F2 is the clamping portion length L3 , and the clamping portion length L3 needs to be smaller than the length of the side of the first mounting hole 121 so that the clamping portion 326 can extend into the first mounting hole 121 .
