TECHNICAL FIELD

[0001] This application relates to the field of electronic device technologies, and in particular, to a hoop and an electronic device.BACKGROUND

[0002] At present, electronic devices such as a router, a camera, and an antenna may be fastened on existing rod bodies such as a railing, a fence, a downpipe, and a lamp post by using hoops.

[0003] For example, FIG. 1 shows a hoop 01 in the conventional technology. As shown in FIG. 1, the hoop 01 includes a steel belt 011 and a steel belt buckle 012, the steel belt 011 is provided with a plurality of fastening holes 013 in a length direction, one end of the steel belt 011 is connected to the steel belt buckle 012, and the steel belt buckle 012 can be connected to any fastening hole 013. In this way, by fastening the steel belt buckle 012 to different fastening holes 013, the hoop 01 can be tightly held onto rod bodies 02 with a plurality of cross-sectional sizes (as shown in FIG. 2). However, because there is a specific spacing between two adjacent fastening holes 013, a scope of the rod bodies 02 to which the hoop 01 shown in FIG. 1 is applicable is still limited. The hoop 01 is not tightly held onto rod bodies of some diameters when being fastened on the rod bodies, resulting in a poor fastening effect.

[0007] To achieve the foregoing objective, the following technical solutions are used in embodiments of this application. The invention is defined in the independent claims. Advantageous features are defined in the dependent claims

[0008] According to a first aspect, an embodiment of this application provides a hoop, including a strap, a strap buckle, a support member, and a driving member. The strap is provided with a plurality of fastening holes in a length direction. The strap buckle includes a buckle head, a buckle body, and a buckle tail, the buckle head and the buckle tail are respectively located on two sides of the buckle body and are connected to the buckle body, the buckle tail is connected to one end of the strap, and the buckle head is capable of being fastened to any one of the fastening holes, so that the strap is held onto an existing rod body. The support member is located on a side that is of the buckle body and that is configured to face the existing rod body, the driving member is connected between the support member and the buckle body, and the driving member is configured to drive the support member to move in a direction close to or away from the buckle body.

[0009] In the hoop provided in this embodiment of this application, the hoop includes the strap and the strap buckle, the strap is provided with the plurality of fastening holes in the length direction, the strap buckle includes the buckle head, the buckle body, and the buckle tail, the buckle head and the buckle tail are respectively located on the two sides of the buckle body and are connected to the buckle body, the buckle tail is connected to one end of the strap, and the buckle head is capable of being fastened to any one of the fastening holes, so that the strap is held onto the existing rod body. In addition, the hoop includes the support member and the driving member, the support member is located on the side that is of the buckle body and that is configured to face the existing rod body, the driving member is connected between the support member and the buckle body, and the driving member is configured to drive the support member to move in the direction close to or away from the buckle body. Therefore, by fastening the buckle head to different fastening holes, the hoop can be directly held tightly onto rod bodies with a plurality of cross-sectional sizes defined by the plurality of fastening holes. When a cross-sectional size of a rod body is different from any one of the plurality of cross-sectional sizes, the strap may wind around the rod body, and the buckle head may be fastened to a fastening hole, so that the strap is held onto the rod body; and then the driving member drives the support member to move in the direction away from the buckle body to press the rod body, so that the strap is tightly held onto the rod body. In this way, the hoop can be tightly held onto the rod body with the cross-sectional size other than the plurality of cross-sectional sizes, thereby increasing a scope of rod bodies to which the hoop is applicable.

[0010] With reference to the first aspect, in a first optional implementation of the first aspect, the driving member is a hand torsion bar, and the hand torsion bar includes a hand torsion part, a screw rod part, and a connecting part that are successively connected in a length direction. The buckle body is provided with a threaded hole, the hand torsion part is located on a side that is of the buckle body and that is away from the support member, the screw rod part is screwed into the threaded hole, and the connecting part is connected to the support member. In this way, the hand torsion part can be operated to drive the support member to move in the direction close to or away from the buckle body. Such a driving member has a simple structure, a small footprint, and low costs.

[0011] With reference to the first optional implementation of the first aspect, in a second optional implementation of the first aspect, the connecting part is rotatably connected to the support member, and an axis of rotation between the connecting part and the support member is collinear with a central axis of the screw rod part. In this way, the support member is not fastened to the connecting part, and when the hand torsion bar is rotated to drive the support member to press the rod body, the support member is not rotated together with the hand torsion bar under the friction action of the rod body. This can avoid friction and wear between the support member and the rod body caused when the rod body is pressed.

[0012] With reference to the second optional implementation of the first aspect, in a third optional implementation of the first aspect, a limiting structure is disposed between the support member and the buckle body, and the limiting structure allows the support member to move in the direction close to or away from the buckle body and prevents the support member from rotating relative to the buckle body. In this way, when the hand torsion bar is rotated, the limiting structure can prevent the support member from rotating relative to the buckle body. This avoids friction between the support member and the rod body caused when the rod body is pressed.

[0013] With reference to the third optional implementation of the first aspect, in a fourth optional implementation of the first aspect, the limiting structure includes a square limiting hole and a limiting protrusion, one of the square limiting hole and the limiting protrusion is disposed on the buckle body, the other one of the square limiting hole and the limiting protrusion is disposed on the support member, an axial direction of the square limiting hole is the same as that of the screw rod part, the limiting protrusion is accommodated in the square limiting hole and is capable of sliding along the axial direction of the square limiting hole, the limiting protrusion has a first side surface and a second side surface, and the first side surface and the second side surface respectively fit in with two opposite inner walls of the square limiting hole. By making the limiting protrusion slide along the axial direction of the square limiting hole, the limiting structure allows the support member to move in the direction close to or away from the buckle body; and by making the two inner side surfaces of the square limiting hole fit in with the first side surface and the second side surface of the limiting protrusion, the limiting structure prevents the limiting protrusion from rotating in the square limiting hole, to prevent the support member from rotating relative to the buckle body. Such a limiting structure is simple and is easy to implement.

[0014] With reference to any one of the first aspect to the fourth optional implementation of the first aspect, in a fifth optional implementation of the first aspect, a strap hole is disposed on the buckle head, the strap hole allows the strap to pass through, a hook-up is disposed on an inner wall of the strap hole, and the fastening hole is capable of being hung on the hook-up. In this way, the strap passes through the strap hole, and the buckle head is fastened to the fastening hole by hanging the fastening hole on the hook-up. Such a structure is simple and is convenient to operate.

[0015] With reference to any one of the first aspect to the fifth optional implementation of the first aspect, in a sixth optional implementation of the first aspect, the hoop further includes an elastic pad. The elastic pad is disposed at least at an end that is of the support member and that is away from the buckle body. In this way, when the driving member drives the support member to move in the direction away from the buckle body to press the rod body, the elastic pad comes into contact with the rod body. This avoids compressive deformation of the rod body.

[0016] With reference to the sixth optional implementation of the first aspect, in a seventh optional implementation of the first aspect, a surface that is of the elastic pad and that is away from the buckle body is provided with an anti-slide structure. In this way, when the hoop in this embodiment of this application is tightly held onto the rod body, the anti-slide structure on the elastic pad comes into contact with the rod body. This can prevent the hoop from sliding down along the rod body.

[0017] With reference to the sixth or the seventh optional implementation of the first aspect, in an eighth optional implementation of the first aspect, the surface that is of the elastic pad and that is away from the buckle body is a first profiling surface, and the first profiling surface is adapted to a surface of the rod body. In this way, when the hoop in this embodiment of this application is tightly held onto the rod body, the first profiling surface fits in with the surface of the rod body, and a fitting area is large, so that a pressing force between the elastic pad and the rod body acts on a larger surface. This avoids compressive deformation of the rod body.

[0018] With reference to any one of the first aspect to the eighth optional implementation of the first aspect, in a ninth optional implementation of the first aspect, the hoop further includes at least one strap accommodation member, each strap accommodation member is provided with first through holes and second through holes, the first through holes and the second through holes are arranged side by side, the strap accommodation member is disposed, through the first through holes, on a part that is of the strap and that is configured to hold onto the existing rod body, and a part that is of the strap and that is not configured to hold onto the existing rod body is capable of being disposed through the second through holes. In this way, the strap accommodation member accommodates the part that is of the strap and that is not configured to hold onto the existing rod body, appearance neatness of the hoop that is present after the hoop is fastened on the rod body is ensured. In addition, the strap accommodation member can slide along the length direction of the strap, to adjust a location of the strap accommodation member, so that the strap accommodation member can accommodate parts of the strap that have different lengths and that are not configured to hold onto the existing rod body.

[0019] With reference to the ninth optional implementation of the first aspect, in a tenth optional implementation of the first aspect, a surface that is of the strap accommodation member and that is configured to fit in with the existing rod body is provided with an anti-slide structure. In this way, when the hoop in this embodiment of this application is tightly held onto the rod body, the anti-slide structure on the strap accommodation member comes into contact with the rod body. This can prevent the hoop from sliding down along the rod body.

[0020] With reference to the ninth or the tenth optional implementation of the first aspect, in an eleventh optional implementation of the first aspect, the surface that is of the strap accommodation member and that is configured to fit in with the existing rod body is a second profiling surface, and the second profiling surface is adapted to the surface of the rod body. In this way, when the hoop in this embodiment of this application is tightly held onto the rod body, the second profiling surface fits in with the surface of the rod body, and a fitting area is large, so that a pressing force between the strap accommodation member and the rod body acts on a larger surface. This avoids damage to the strap accommodation member and the rod body during mutual pressing.

[0021] With reference to the ninth, the tenth, or the eleventh optional implementation of the first aspect, in a twelfth optional implementation of the first aspect, a material of the strap accommodation member is silica gel. Silica gel has high toughness and can be prevented from being scratched by the strap when sliding along the strap.

[0022] With reference to any one of the first aspect to the twelfth optional implementation of the first aspect, in a thirteenth optional implementation of the first aspect, a thickness of the strap is 0.2 mm to 0.4 mm. In this way, a minimum bending radius of the strap is small, and the strap can be tightly held onto a rod body whose cross section is rectangular, triangular, prismatic, or the like.

[0023] With reference to any one of the first aspect to the thirteenth optional implementation of the first aspect, in a fourteenth optional implementation of the first aspect, a material of the strap is 316 stainless steel. 316 stainless steel has high tensile strength and is resistant to corrosion and a high temperature, and a lifespan of the strap is long.

A base of the electronic device body is provided with a third through hole, and the electronic device body is disposed on the strap through the third through hole.

[0025] Because the hoop used in the electronic device in this embodiment of this application is the same as the hoop according to the foregoing technical solutions, the two hoops can resolve a same technical problem and achieve a same expected effect.

DESCRIPTION OF EMBODIMENTS

[0028] Electronic devices such as an outdoor wireless router and a road surveillance camera are widely deployed in outdoor scenarios to implement wireless sharing, traffic violation capture, and traffic flow monitoring within a specific range. Specifically, the electronic devices may be fastened on existing rod bodies in outdoor scenarios, to reduce deployment costs of the electronic devices. For example, the electronic devices may be fastened on existing rod bodies such as a lamp post, a railing, a fence, and a downpipe. To make weights of the existing rod bodies (for example, a railing and a fence) light, or to make fluid media capable of being transmitted or electrical connection cables capable of being deployed inside the existing rod bodies (for example, a downpipe and a lamp post), the existing rod bodies usually have hollow structures with small wall thicknesses. If the electronic devices are connected to the existing rod bodies by using threaded connectors (for example, a bolt and a screw), holes need to be drilled on the rod bodies. Consequently, liquid media in the rod bodies leak, and structural strength of the rod bodies is greatly reduced. In addition, because the wall thicknesses of the existing rod bodies are small, threaded fitting sizes between the threaded connectors and the existing rod bodies are small, and the electronic devices cannot be securely connected to the rod bodies. If the electronic devices are connected to the existing rod bodies through welding, heat generated during welding is prone to damage the electronic devices. Moreover, the electronic devices are in line contact with the existing rod bodies, a welding area is small, an operation is difficult, and welding strength is low.

[0029] To avoid the foregoing problems, an electronic device may be fastened on an existing rod body by using a hoop. The hoop includes a strap and a strap buckle, the strap is provided with a plurality of fastening holes along a length direction, one end of the strap is connected to the strap buckle, and the strap buckle is capable of being fastened to any one of the fastening holes, so that the strap is held onto an existing rod body. The electronic device is disposed on a part that is of the strap and that is held onto the existing rod body, so that the electronic device is fastened on the existing rod body. However, because there is a specific spacing between two adjacent fastening holes, a scope of rod bodies to which the hoop is applicable is limited. The hoop is not tightly held onto rod bodies of some diameters when being fastened on the rod bodies, resulting in a poor fastening effect.

[0030] In view of this, some embodiments of this application provide an electronic device (as shown in FIG. 3), including an electronic device body 2 and a hoop 1. The electronic device body 2 includes but is not limited to an outdoor wireless router or a road surveillance camera. In some embodiments, as shown in FIG. 3, the electronic device body 2 is an outdoor wireless router.

[0031] Some embodiments of this application provide a hoop 1 (as shown in FIG. 5 or FIG. 9). The hoop 1 includes a strap 11, a strap buckle 12, a support member 13, and a driving member 14. The strap 11 is provided with a plurality of fastening holes 111 in a length direction. The strap buckle 12 includes a buckle head 121, a buckle body 122, and a buckle tail 123, the buckle head 121 and the buckle tail 123 are respectively located on two sides of the buckle body 122 and are connected to the buckle body 122, the buckle tail 123 is connected to one end of the strap 11, and the buckle head 121 is capable of being fastened to any one of the fastening holes 111, so that the strap 11 is held onto an existing rod body. The support member 13 is located on a side that is of the buckle body 122 and that is configured to face the existing rod body, the driving member 14 is connected between the support member 13 and the buckle body 122, and the driving member 14 is configured to drive the support member 13 to move in a direction close to or away from the buckle body 122.

[0032] As shown in FIG. 3, the electronic device body 2 includes a base 21, the base 21 is provided with a third through hole 22, and the electronic device body 2 is disposed on the strap 11 of the hoop 1 through the third through hole 22.

[0033] In the hoop provided in this embodiment of this application, as shown in FIG. 5 or FIG. 9, the hoop 1 includes the strap 11 and the strap buckle 12, the strap 11 is provided with the plurality of fastening holes 111 in the length direction, the strap buckle 12 includes the buckle head 121, the buckle body 122, and the buckle tail 123, the buckle head 121 and the buckle tail 123 are respectively located on the two sides of the buckle body 122 and are connected to the buckle body 122, the buckle tail 123 is connected to one end of the strap 11, and the buckle head 121 is capable of being fastened to any one of the fastening holes 111, so that the strap 11 is held onto the existing rod body. In addition, the hoop 1 includes the support member 13 and the driving member 14, the support member 13 is located on the side that is of the buckle body 122 and that is configured to face the existing rod body, the driving member 14 is connected between the support member 13 and the buckle body 122, and the driving member 14 is configured to drive the support member 13 to move in the direction close to or away from the buckle body 122. Therefore, by fastening the buckle head 121 to different fastening holes 111, the hoop 1 carrying the electronic device can be directly held tightly onto rod bodies 100 with a plurality of cross-sectional sizes defined by the plurality of fastening holes 111 (as shown in FIG. 4). When a cross-sectional size of a rod body is different from any one of the plurality of cross-sectional sizes, without changing a spacing between two adjacent fastening holes 111 on the strap 11, the buckle body 122 may be used as a reference after the strap 11 is held onto the rod body 100 by using the strap buckle 12. The driving member 14 drives the support member 13 to move in the direction away from the buckle body 122, so that the support member 13 presses the rod body 100, and the strap 11 is tightly held onto the rod body 100. In this way, the hoop 1 can be tightly held onto the rod body with the cross-sectional size other than the plurality of cross-sectional sizes, thereby increasing a scope of rod bodies to which the hoop 1 is applicable.

[0034] Because the hoop 1 used in the electronic device in this embodiment of this application is the same as the hoop 1 according to the foregoing technical solutions, the two hoops 1 can resolve a same technical problem and achieve a same expected effect.

[0035] In this embodiment of this application, a maximum travel of the driving member 14 for driving the support member 13 to move may be 1 mm, 2 mm, 3 mm, or the like. This is not specifically limited herein. In some embodiments, the maximum travel of the driving member 14 for driving the support member 13 to move needs to be greater than or equal to a distance between any two adjacent fastening holes on the strap 11. In this way, the hoop 1 can be tightly held onto a rod body with a cross-sectional size between two cross-sectional sizes defined by any two adjacent fastening holes on the strap 11, thereby increasing a scope of rod bodies to which the hoop provided in this embodiment of this application is applicable.

[0036] A material of the strap 11 includes but is not limited to metal, plastic, or gauze. In some embodiments, the material of the strap 11 is 316 stainless steel. 316 stainless steel has high tensile strength and is resistant to corrosion and a high temperature, and a lifespan of the strap 11 can be prolonged.

[0037] A thickness of the strap 11 includes but is not limited to 1.2 mm, 1.0 mm, 0.8 mm, or 0.6 mm. In some embodiments, the thickness of the strap 11 is 0.2 mm to 0.4 mm. In this way, the thickness of the strap 11 is small, a minimum bending radius of the strap 11 is small, and the strap 11 can be tightly held onto a rod body whose cross section is rectangular, triangular, prismatic, or the like.

[0038] The buckle tail 123 may be connected to one end of the strap 11 through welding, riveting, or the like. This is not specifically limited herein. In some embodiments, as shown in FIG. 7 or FIG. 11, the buckle tail 123 includes a rotating shaft 1231, and two ends of the rotating shaft 1231 are connected to the buckle body 122. As shown in FIG. 5 or FIG. 9, one end of the strap 11 winds around the rotating shaft 1231 and is then bent reversely, and is fixedly connected to a part that is of the strap 11 and that does not wind around the rotating shaft 1231, so that the strap 11 can rotate around the rotating shaft 1231. This facilitates adjustment of an angle of the strap 11 relative to the strap buckle 12, so that the strap 11 fits in with a surface of the to-be-held rod body, so as to be tightly held onto the to-be-held rod body. In some embodiments, the part that is of the strap 11 and that winds around the rotating shaft 1231 and the part that is of the strap 11 and that does not wind around the rotating shaft 1231 are fixedly connected to each other by using at least one rivet 15. Surface flatness that is present after riveting is performed by using the rivet 15 is desirable, and no sharp protrusion appears. Therefore, the to-be-held rod body or installation personnel are not scratched.

In this way, the hand torsion part 141 can be operated to drive the support member 13 to move in the direction close to or away from the buckle body 122. Such a driving member 14 has a simple structure, a small footprint, and low costs.

[0041] The connecting part 143 may be fixedly or rotatably connected to the support member 13. This is not specifically limited herein. In some embodiments, as shown in FIG. 8 or FIG. 12, the connecting part 143 may be rotatably connected to the support member 13, and an axis of rotation between the connecting part 143 and the support member 13 is collinear with a central axis of the screw rod part 142. In this way, the support member 13 is not fastened to the connecting part 143, and when the hand torsion bar is rotated to drive the support member 13 to press the rod body, the support member 13 is not rotated together with the hand torsion bar under the friction action of the rod body. This can avoid friction and wear between the support member 13 and the rod body caused when the rod body is pressed.

[0042] To implement the rotatable connection between the connecting part 143 and the support member 13, in some embodiments, as shown in FIG. 8 or FIG. 12, the connecting part 143 includes a rotating shaft 1431 and a stopping structure 1432, one end of the rotating shaft 1431 is fastened to the screw rod part 142, a central axis of the rotating shaft 1431 is collinear with the central axis of the screw rod part 142, a diameter of the rotating shaft 1431 is less than a diameter of the screw rod part 142, and a shaft shoulder c is formed between the rotating shaft 1431 and the screw rod part 142; and the support member 13 is provided with a connecting hole 131, the support member 13 is disposed on the rotating shaft 1431 through the connecting hole 131, the shaft shoulder c stops at one side of the support member 13, the stopping structure 1432 is connected to the other end of the rotating shaft 1431, and the stopping structure 1432 stops at the other side of the support member 13.

In some embodiments, as shown in FIG. 7 or FIG. 11, the hook-up 16 is disposed on the inner wall of one end that is of the strap hole 1211 and that is away from the buckle body 122. In this way, after the strap 11 passes through the strap hole 1211 and the fastening hole 111 is hung on the hook-up 16, the strap 11 is bent reversely, to prevent the fastening hole 111 from being released from the hook-up 16. This enables a convenient operation and desirable appearance neatness.

[0049] A material of the support member 13 includes but is not limited to metal, plastic, silica gel, or rubber. The support member 13 may be entirely made of a rigid material, or may be entirely made of an elastic material, or may be partially made of a rigid material and partially made of an elastic material. This is not specifically limited herein.

[0050] In some embodiments, as shown in FIG. 6 or FIG. 10, the hoop 1 further includes an elastic pad 17. The elastic pad 17 is disposed at least at an end that is of the support member 13 and that is away from the buckle body 122. In this way, when the driving member 14 drives the support member 13 to move in the direction away from the buckle body 122 to press the rod body, the elastic pad 17 comes into contact with the rod body. This avoids compressive deformation of the rod body.

[0051] In the foregoing embodiment, that the elastic pad 17 is disposed at least at an end that is of the support member 13 and that is away from the buckle body 122 means: The elastic pad 17 may be disposed only at the end that is of the support member 13 and that is away from the buckle body 122, or may be disposed at the end that is of the support member 13 and that is away from the buckle body 122 and disposed at another part of the support member 13. This is not specifically limited herein. In some embodiments, as shown in FIG. 8, the elastic pad 17 is disposed only at the end that is of the support member 13 and that is away from the buckle body 122. In some other embodiments, as shown in FIG. 12, the elastic pad 17 is disposed at the end that is of the support member 13 and that is away from the buckle body 122 and disposed on a side surface of the support member 13. That the elastic pad 17 is disposed at the end that is of the support member 13 and that is away from the buckle body 122 specifically means: The elastic pad 17 may cover an entire end surface of the end that is of the support member 13 and that is away from the buckle body 122 (as shown in FIG. 8 or FIG. 12), or cover only a partial end face of the end that is of the support member 13 and that is away from the buckle body 122. For example, the elastic pad 17 covers only an edge region of the end face of the end that is of the support member 13 and that is away from the buckle body 122. This is not specifically limited herein.

[0052] In some embodiments, as shown in FIG. 6, a surface that is of the elastic pad 17 and that is away from the buckle body 122 is provided with an anti-slide structure a. In this way, when the hoop 1 in this embodiment of this application is tightly held onto the rod body, the anti-slide structure a on the elastic pad 17 comes into contact with the rod body. This can prevent the hoop 1 from sliding down along the rod body.

[0053] There are a plurality of structural forms for the anti-slide structure a. This is not specifically limited herein. In some embodiments, as shown in FIG. 6, the anti-slide structure a is a plurality of ribs uniformly disposed on the surface that is of the elastic pad 17 and that is away from the buckle body 122, and the plurality of ribs are arranged intersecting each other.

[0054] In some embodiments, the surface that is of the elastic pad 17 and that is away from the buckle body 122 is a first profiling surface, and the first profiling surface is adapted to the surface of the rod body. In this way, when the hoop 1 in this embodiment of this application is tightly held onto the rod body, the first profiling surface fits in with the surface of the rod body, and a fitting area is large, so that a pressing force between the elastic pad 17 and the rod body acts on a larger surface. This avoids compressive deformation of the rod body.

[0055] In some embodiments, as shown in FIG. 5 or FIG. 9, the hoop 1 further includes at least one strap accommodation member 18. As shown in FIG. 6, each strap accommodation member 18 is provided with first through holes 181 and second through holes 182, the strap accommodation member 18 is disposed, through the first through holes 181, on a part that is of the strap 11 and that is configured to hold onto the existing rod body, and a part that is of the strap 11 and that is not configured to hold onto the existing rod body is capable of being disposed through the second through holes 182. In this way, the strap accommodation member 18 accommodates the part that is of the strap 11 and that is not configured to hold onto the existing rod body, appearance neatness of the hoop 1 that is present after the hoop 1 is fastened on the rod body is ensured. In addition, the strap accommodation member 18 can slide along the length direction of the strap 11, to adjust a location of the strap accommodation member 18, so that the strap accommodation member 18 can accommodate parts of the strap that have different lengths and that are not configured to hold onto the existing rod body.

[0056] There may be one, two, three, or more strap accommodation members 18. This is not specifically limited herein. In some embodiments, as shown in FIG. 5 or FIG. 9, there are two strap accommodation members 18. In this way, the strap accommodation members 18 can accommodate parts of the strap that have a large length and that are not configured to hold onto the existing rod body, and the quantity of the strap accommodation members 18 is relatively small, so that structural complexity and costs of the hoop 1 can be reduced.

[0057] The first through holes 181 and the second through holes 182 may be arranged side by side (that is, an axial direction of the first through holes 181 and an axial direction of the second through holes 182 are parallel to each other), may be perpendicular to each other (that is, the axial direction of the first through holes 181 and the axial direction of the second through holes 182 are perpendicular to each other), or may be in another orientation relationship. This is not specifically limited herein. In some embodiments, as shown in FIG. 6, the first through holes 181 and the second through holes 182 are arranged side by side, and the first through holes 181 and the second through holes 182 are arranged along a thickness direction of the strap 11. In this way, when the strap 11 winds around the rod body, the buckle head 121 is fastened to a fastening hole 111 so that the strap 11 is held onto the rod body, and the part that is of the strap 11 and that is not configured to hold onto the existing rod body is disposed through the second through holes 182, the part that is of the strap 11 and that is not configured to hold onto the existing rod body partially overlaps the part that is of the strap 11 and that is held onto the rod body. This enables desirable appearance neatness.

[0058] The first through holes 181 and the second through holes 182 may be independent of each other, or may penetrate through each other. This is not specifically limited herein. In some embodiments, as shown in FIG. 6, the first through holes 181 and the second through holes 182 are independent of each other, to avoid friction between the part that is of the strap 11 and that is disposed through the first through holes 181 and the part that is of the strap 11 and that is disposed through the second through holes 182. In some other embodiments, the first through holes 181 and the second through holes 182 penetrate through each other. In this way, only one through hole needs to be formed on the strap accommodation member 18. Therefore, the strap accommodation member 18 has a simple structure and is easy to fabricate.

[0059] In some embodiments, as shown in FIG. 6, a surface that is of the strap accommodation member 18 and that is configured to fit in with the existing rod body is provided with an anti-slide structure b. In this way, when the hoop 1 in this embodiment of this application is tightly held onto the rod body, the anti-slide structure b on the strap accommodation member 18 comes into contact with the rod body. This can prevent the hoop 1 from sliding down along the rod body.

[0060] There are a plurality of structural forms for the anti-slide structure b. This is not specifically limited herein. In some embodiments, as shown in FIG. 6, the anti-slide structure b is a plurality of ribs uniformly disposed on the inner surface of the strap accommodation member 18, and the plurality of ribs are arranged intersecting each other.

[0061] In some embodiments, the surface that is of the strap accommodation member 18 and that is configured to fit in with the existing rod body is a second profiling surface, and the second profiling surface is adapted to the surface of the rod body. In this way, when the hoop 1 in this embodiment of this application is tightly held onto the rod body, the second profiling surface fits in with the surface of the rod body, and a fitting area is large, so that a pressing force between the strap accommodation member 18 and the rod body acts on a larger surface. This avoids damage to the strap accommodation member 18 and the rod body during mutual pressing

[0062] A material of the strap accommodation member 18 includes but is not limited to plastic, silica gel, rubber, or metal. In some embodiments, the material of the strap accommodation member 18 is silica gel. Silica gel has high toughness and can be prevented from being scratched by the strap 11 when sliding along the strap 11.

[0063] In some embodiments, the electronic device body is provided with a third through hole, and the electronic device body is disposed on the strap 11 through the third through hole. In this way, the electronic device body may slide along the strap 11, to adjust a location of the electronic device body on the strap 11.

[0064] In the descriptions of this specification, the specific features, structures, materials, or characteristics may be combined in a proper manner in any one or more of embodiments or examples.

[0065] Finally, it should be noted that the foregoing embodiments are merely intended to describe the technical solutions of this application, but not to limit this application.
