At least part of the clamping portion abuts against the side wall of the moving member, and the clamping block is limited and received in the clamping groove to assemble and fix the fixing member and the moving member.

[0007] As a further improvement of the present invention, a stop surface is formed on the clamping block. When the clamping block is received in the clamping groove, the stop surface abuts against the inner wall surface of the clamping groove.

[0008] As a further improvement of the present invention, the stop surface is perpendicular to the clamping portion. An inclined guiding surface is also formed on the clamping block. The guiding surface is connected to the stop surface. When the moving member is inserted into the fixing member, the guiding surface contacts the side wall of the moving member and guides the clamping block into the clamping groove until the stop surface abuts against the inner wall surface of the clamping groove.

[0009] As a further improvement of the present invention, the clamping portion further includes a guiding strip connected to the clamping block. The extending direction of the guiding strip is perpendicular to the protruding direction of the clamping portion.

[0033] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Please refer to Figure 1 and Figure 2 As shown, the present invention discloses an installation structure 200 and a lamp 100 applying the installation structure 200, which are used to realize the tool - free disassembly or installation between the lamp 100 and the installation surface. The lamp 100 includes a light - emitting module 300 and an installation structure 200. Among them, the installation structure 200 is fixedly installed on the installation surface, the light - emitting module 300 is received in the installation structure 200, and emits light to the outside, so as to realize the installation of the lamp 100 on the installation surface and illuminate other objects.

[0035] Please refer to Figures 3 to 7 As shown, the installation structure 200 includes a fixing member 1, a movable member 2 and a mounting member (not shown). The fixing member 1 is connected to the installation surface through the mounting member. The connection between the movable member 2 and the fixing member 1 is detachable, so as to realize the convenient installation or disassembly between the fixing member 1 and the movable member 2. One end of the movable member 2 away from the fixing member 1 is recessed to form a receiving cavity 223, and the light - emitting module 300 is received in the receiving cavity 223 to emit light to the outside to illuminate other objects.

[0036] The fixing member 1 includes a clamping portion 11, a fixed plate 12 and a contact portion 13. Among them, the fixed plate 12 is fixedly connected to the contact portion 13 and the clamping portion 11 respectively. The contact portion 13 and the clamping portion 11 both protrude outward from the fixed plate 12. The fixed plate 12 is provided with a mounting hole 121, a through hole 122 and a movable hole 123 that penetrate the fixed plate 12.

[0037] In this embodiment, there are four mounting holes 121, and the four mounting holes 121 are rotationally symmetric with respect to the center of the fixing plate 12. The mounting holes 121 are elliptical and match the size of the mounting member, so that the mounting member can pass through the mounting holes 121 to be connected to the mounting surface, thereby fixedly mounting the fixing member 1 to the mounting surface. Of course, in other embodiments, the number of the mounting holes 121, the opening position on the fixing plate 12, the shape and size of the mounting holes 121 can be set according to actual situations; it is even possible not to provide the mounting holes 121 and the mounting member, and directly connect the fixing member 1 and the mounting surface through a connecting adhesive or other means, as long as the fixing member 1 can be fixedly mounted on the mounting surface, and no restrictions are made here. In this embodiment, the mounting member is preferably a screw.

[0038] The through hole 122 is circularly arranged and opened at the center position of the fixing plate 12. The through hole 122 can be used as a power supply hole for the light-emitting module 300 to be electrically connected to the outside, or as a connection hole for the fixing plate 12 to be connected to the mounting surface. When the through hole 122 is used as a power supply hole, an external power cord can pass through the power supply hole to be electrically connected to the light-emitting module 300 to provide electrical energy for the light-emitting module 300; when the through hole 122 is used as a connection hole, one end of an external connection tool (such as a rope, etc.) can pass through the connection hole and be connected to the fixing plate 12, and the other end is connected to the mounting surface, so as to realize hanging the fixing member 1 on the mounting surface.

[0039] The movable holes 123 are arc-shaped and there are multiple movable holes 123 provided on the fixing plate 12. The multiple movable holes 123 penetrate the fixing plate 12 and are rotationally symmetric with respect to the central axis of the fixing plate 12. Preferably, there are four movable holes 123 and they are evenly distributed on the fixing plate 12. Of course, in other embodiments, the number and shape of the movable holes 123 can be set according to actual situations. For example, the movable holes 123 can be provided with three, five or other numbers, and the shape can be a square hole, a circular hole or a polygonal hole, and no restrictions are made here.

[0040] Please refer to Figure 6 and Figure 7 As shown, the abutting portion 13 includes an abutting arm 131 and a convex platform 132. Specifically, the abutting arm 131 is provided on the side of the fixing plate 12 away from the mounting surface and extends obliquely in a direction away from the mounting surface, and the convex platform 132 is provided at one end of the abutting arm 131 away from the fixing plate 12. That is to say, one end of the abutting arm 131 is connected to the fixing plate 12, and the other end is connected to the convex platform 132.

[0041] The abutting arm 131 is an arc-shaped elastic arm, which can deform and provide an elastic abutting force when the fixing member 1 and the moving member 2 are assembled and fixed, so as to ensure the assembly stability of the fixing member 1 and the moving member 2. Specifically, the abutting arm 131 is set as an arc-shaped cuboid. Of course, in other embodiments, the abutting arm 131 can also be set according to the actual situation. For example, the abutting arm 131 is set as a curved circle, or the abutting arm 131 is a regular cuboid or circle, and no restrictions are made here.

[0042] The abutting arm 131 is torn from the fixing member 1. Specifically, one end of the abutting arm 131 connected to the fixing plate 12 is connected to the inner wall surface of the moving hole 123. That is to say, the abutting arm 131 extends from the inner wall surface of the moving hole 123 to the side away from the fixing plate 12. The extending direction of the abutting arm 131 corresponds to the opening direction of the moving hole 123. In other words, on the basis of not considering the spatial structure, the abutting arm 131 can be completely accommodated in the moving hole 123. In this application, the included angle between the extending direction of the abutting arm 131 and the plane where the fixing plate 12 is located is greater than 0° and less than or equal to 90°. That is to say, as long as the abutting arm 131 extends outward from the fixing plate 12, the extending direction of the abutting arm 131 is not restricted.

[0043] In this embodiment, there are at least two abutting parts 13, and the two abutting parts 13 are evenly distributed on the fixing member 1. Preferably, there are four abutting arms 131. The four abutting arms 131 surround a circle on the fixing member 1. And in this circle, each abutting arm 131 extends obliquely in the clockwise direction. At the same time, the shape, size and quantity of the abutting arms 131 correspond to the shape, size and quantity of the moving holes 123 respectively. The four abutting arms 131 and the moving holes 123 are rotationally symmetrically arranged with respect to the central axis of the fixing plate 12. Of course, in other embodiments, the quantity of the abutting arms 131 and the moving holes 123 can be set according to the actual situation, and no restrictions are made here.

[0044] The boss 132 is arranged at one end of the abutting arm 131 away from the fixing plate 12 and extends outward from the abutting arm 131. The extending direction is perpendicular to the central axis of the fixing plate 12. In other words, the plane where the boss 132 is located is parallel to the plane where the fixing plate 12 is located. Specifically, the boss 132 is a flat plate-like structure parallel to the plane where the fixing member 1 is located. The boss 132 includes an abutting surface 133. The abutting surface 133 is arranged on the side of the boss 132 away from the fixing plate 12 and is parallel to the plane where the fixing plate 12 is located.

[0045] Please refer to Figures 3 to 7As shown, the clamping portion 11 includes a clamping block 111 and a guiding strip 114. The clamping portion 11 extends from the edge of the fixing plate 12 towards the side away from the mounting surface. That is to say, one end of the clamping portion 11 is fixedly connected to the edge of the fixing plate 12, and the other end away from the fixing plate 12 is provided with a clamping block 111 and a guiding strip 114. In this embodiment, the clamping portion 11 extends from the outer side of the edge of the fixing plate 12 towards the direction away from the mounting surface, that is, the clamping portion 11 is arranged perpendicular to the fixing plate 12. Of course, in other embodiments, the clamping portion 11 can also be arranged inside the edge of the fixing plate 12, as long as the clamping portion 11 is fixedly connected to the fixing plate 12 and extends from the fixing plate 12 towards the side away from the mounting surface, and no limitation is made here.

[0046] In this embodiment, the fixing plate 12 is circularly arranged, and the clamping portion 11 is an elastic arm in the shape of a hook suspended in the circumferential direction of the fixing member 1. There are four clamping portions 11, and they are rotationally symmetric with respect to the center of the fixing plate 12. Of course, in other embodiments, the number of the clamping portions 11 can be set according to actual situations, and can be set to two, three or other numbers. The shape and material of the clamping portion 11 can also be set according to actual situations. For example, it can be cylindrical or polygonal prism-shaped. The clamping portion 11 can be entirely made of a slightly elastic material or partially made of a slightly elastic material. No limitation is made here on the shape and material of the clamping portion 11.

[0047] The clamping block 111 is arranged at the end of the clamping portion 11 away from the fixing plate 12. The clamping block 111 extends outward from the clamping portion 11, and the angle between the extending direction of the clamping block 111 and the extending direction of the clamping portion 11 is greater than 0° and less than or equal to 90°. Preferably, the angle between the extending direction of the clamping block 111 and the extending direction of the clamping portion 11 is 90°. That is to say, the extending direction of the clamping block 111 is perpendicular to the extending direction of the clamping portion 11.

[0048] A guiding surface 112 and a stopping surface 113 are formed on the clamping block 111. Specifically, the cross-section of the clamping block 111 is in the shape of a right trapezoid or a right triangle. Among them, one right-angled side is fixedly connected or integrally arranged with the clamping portion 11, and the other right-angled side perpendicular to the clamping portion 11 is the stopping surface 113, and the hypotenuse connecting the two right-angled sides is the guiding surface 112. That is to say, the guiding surface 112 inclines from the clamping portion 11 towards the fixing plate 12 and is connected to the stopping surface 113. Thus, when the clamping portion 11 abuts against other components, the guiding surface 112 can guide the clamping portion 11 to contact other components until it is placed inside or outside other components; the stopping surface 113 can limit the clamping portion 11 from randomly detaching from other components.

[0049] In this embodiment, the clamping block 111 extends in the direction of the central axis of the fixing plate 12 from the clamping portion 11. That is to say, the guiding surface 112 of the clamping block 111 extends from the end of the clamping portion 11 towards the fixing plate 12, and the stopping surface 113 extends in the direction of the central axis of the fixing plate 12. Of course, in other embodiments, the clamping block 111 can also be set according to actual situations. For example, the clamping block 111 extends from the clamping portion 11 in the direction away from the central axis of the fixing plate 12; and the clamping block 111 is arranged at other angles with the clamping portion 11; as long as the clamping block 111 is fixedly connected to the clamping portion 11 and the guiding surface 112 and the stopping surface 113 are provided on the clamping block 111, there is no restriction here.

[0050] The guiding strip 114 is fixedly connected to the clamping block 111 and extends outwards from the clamping block 111 to form a free end. Specifically, the extending direction of the guiding strip 114 is perpendicular to the protruding direction of the clamping portion 11, and the angle between the extending direction of the guiding strip 114 and the plane where the clamping portion 11 is located is greater than or equal to 0° and less than or equal to 90°. It can also be understood that: the guiding strip 114 extends obliquely outwards from the clamping block 111.

[0051] In this embodiment, the guiding strip 114 extends from the clamping block 111 in the direction away from the central axis of the fixing plate 12. Of course, in other embodiments, the guiding strip 114 can also extend from the clamping block 111 in the direction of the central axis of the fixing plate 12. At the same time, the extending direction of the guiding strip 114 can be parallel to the plane where the clamping portion 11 is located or perpendicular to the plane where the clamping portion 11 is located, and there is no restriction here.

[0052] At least one inclined surface is provided on the guiding strip 114. That is to say, at least one side surface of the guiding strip 114 is inclined with respect to the clamping portion 11. Specifically, in this embodiment, the guiding strip 114 extends in the direction away from the central axis of the fixing plate 12, and the side surface of the guiding strip 114 close to the central axis of the fixing plate 12 is an inclined surface. Of course, in other embodiments, when the guiding strip 114 extends in the direction close to the central axis of the fixing plate 12, the side surface of the guiding strip 114 away from the central axis of the fixing plate 12 is the inclined surface; when the extending direction of the guiding strip 114 is parallel to the plane where the clamping portion 11 is located, the inclined surface can be arranged either close to the central axis of the fixing plate 12 or away from the central axis of the fixing plate 12, and there is no restriction here.

[0053] In this embodiment, two guiding strips 114 are provided on each clamping portion 11. The two guiding strips 114 extend outwards from both ends of the clamping block 111 respectively, and the extending directions are both in the direction away from the central axis of the fixing plate 12. Of course, in other embodiments, only one guiding strip 114 can be provided, and there is no restriction here.

[0054] Please refer toFigures 8 to 11 As shown, in the preferred embodiment of the present application, the moving member 2 is cylindrically arranged and includes an inner housing 22, an outer housing 23, a receiving groove 24, and a card slot 21. Specifically, one end of the inner housing 22 is fixedly connected to the outer housing 23, and the outer housing 23 surrounds the outer side of the inner housing 22 to form a receiving groove 24 between the inner housing 22 and the outer housing 23 for receiving the fixing member 1. In other words, the inner housing 22 is received in the outer housing 23 and the bottom end of the inner housing 22 is fixedly connected to the bottom end of the outer housing 23. It can also be said that one end of the inner housing 22 away from the fixing member 1 extends a part in all directions and then changes direction to extend towards the fixing member 1 to form the outer housing 23, so as to form a receiving groove 24 for receiving the fixing member 1 between the inner housing 22 and the outer housing 23.

[0055] The inner housing 22 includes a top plate 221, a side wall 222, and a receiving cavity 223. Specifically, the top plate 221 is formed on the side of the inner housing 22 close to the fixing member 1 and is circularly arranged. The side wall 222 is fixedly connected to the outer peripheral edge of the top plate 221 to form a ring shape. The receiving cavity 223 is formed between the top plate 221 and the side wall 222. The side of the side wall 222 away from the top plate 221 extends in all directions to connect to the outer housing 23.

[0056] In this embodiment, when assembling the fixing member 1 and the moving member 2, the abutting surface 133 on the boss 132 will directly contact and abut against the top plate 221 of the inner housing 22. Therefore, at this time, the top plate 221 of the inner housing 22 can also serve as the docking portion 211 that abuts against the abutting surface 133. Of course, in other embodiments, the docking portion can also be provided as an independent component, which is not limited here and will not be exemplified anymore.

[0057] The top plate 221 is a circular plate-like structure, and a wire passing hole 2211 is opened on the top plate 221. The wire passing hole 2211 is elliptically arranged and opened at a position close to the edge of the top plate 221. In this embodiment, one wire passing hole 2211 is opened, but this should not be taken as a limit.

[0058] One side of the top plate 221 close to the installation surface abuts against the abutting portion 13, and the top plate 221 can slide relative to the abutting portion 13 to realize the installation guidance between the fixing member 1 and the moving member 2. Specifically, the top plate 221 abuts against the boss 132 and can rotate relative to the boss 132 to realize the installation guidance between the fixing member 1 and the moving member 2. During installation, the fixing member 1 is installed on the installation surface, and a pressure towards the installation surface direction is applied to the moving member 2, so that the moving member 2 moves towards the fixing member 1 until the top plate 221 abuts against the boss 132, making the moving member 2 unable to continue moving towards the fixing member 1 to realize the limitation of the moving member 2. The abutting arm 131 has elasticity, which can keep the same distance between the moving member 2 and the fixing member 1. The installer can sense the distance between the moving member 2 and the fixing member 1 through the change of the applied pressure, so as to realize the installation guidance of the lamp 100.

[0059] The clamping groove 21 is arranged on the side wall 222 of the moving member 2 and communicates with the receiving groove 24. There are four clamping grooves 21 corresponding to the clamping portions 11 respectively. When connecting, at least part of the clamping portion 11 is received in the clamping groove 21 to realize the positioning installation of the fixing member 1 and the moving member 2. Specifically, in this embodiment, the clamping groove 21 is opened on the inner housing 22; of course, in other embodiments, the clamping groove 21 can also be opened on the outer housing 23.

[0060] The clamping groove 21 is a rectangular groove and is opened on the side wall 222 of the inner housing 22 and penetrates through the side wall 222 of the inner housing 22, so as to facilitate the clamping block 111 to protrude into the clamping groove 21 when the fixing member 1 and the moving member 2 are assembled and fixed; of course, the clamping groove 21 can also not penetrate through the side wall 222 of the inner housing 22. At this time, the clamping groove 21 is a blind groove formed by recessing from the outer side wall to the inner side wall of the inner housing 22, and can also realize the clamping and fixing of the clamping block 111 and the clamping groove 21; of course, in other embodiments, the opening position of the clamping groove 21 can be set according to the actual situation. For example: the clamping groove 21 can also be opened on the inner side wall or the outer side wall of the outer housing 23, or can also be opened on the inner side wall of the inner housing 22, as long as the clamping and fixing of the clamping block 111 and the clamping groove 21 can be realized, and there is no limitation here.

[0061] The shape, size, and quantity of the card slot 21 and the clamping block 111 correspond to each other. Preferably, both the card slot 21 and the clamping block 111 have four and are rotationally symmetric with respect to the central axis of the fixing plate 12. The distance between the card slot 21 and the top plate 221 is less than or equal to the distance between the clamping block 111 and the fixing plate 12. Preferably, the shortest distance between the clamping block 111 and the fixing plate 12 is equal to the shortest distance between the card slot 21 and the top plate 221 plus the shortest distance between the abutting surface 133 and the fixing plate 12. During installation, when the fixing plate 12 and the moving member 2 are in mutual abutment, the plane formed by the multiple card slots 21 coincides with the plane formed by the multiple clamping blocks 111. Of course, in other embodiments, the shapes, sizes, and quantities of the card slot 21 and the clamping block 111 can also be set differently, as long as some or all of the clamping blocks 111 can be correspondingly received in the card slot 21, and no restrictions are imposed here.

[0062] Please refer to Figure 8 and Figure 9 As shown, as the best embodiment of the present application, the side of the fixing member 1 away from the clamping portion 11 is attached to the installation surface and is fixedly connected to the installation surface through the installation member passing through the installation hole 121. When the fixing member 1 and the moving member 2 are connected, the clamping portion 11 is received in the receiving groove 24 and at least partially abuts against the outer side wall of the inner housing 22. The clamping block 111 extends from the clamping portion 11 in the direction of the central axis of the fixing member 1. The card slot 21 is opened on the outer side wall of the inner housing 22. The abutting portion 13 is disposed between the fixing plate 12 and the top plate 221, applying pressure to the moving member 2 so that the abutting portion 13 abuts against the top plate 221. At the same time, the clamping block 111 is limited and received in the card slot 21, and the stopping surface 113 abuts against the inner wall surface of the card slot 21 to achieve the positioning installation of the fixing member 1 and the moving member 2.

[0063] Specifically: The shapes and sizes of the fixing member 1 and the moving member 2 are similar. When the fixing member 1 is connected to the moving member 2, the end of the clamping portion 11 away from the fixing plate 12 abuts against the edge of the side wall 222 of the moving member 2. By applying pressure to the moving member 2, the edge of the side wall 222 of the moving member 2 slides along the guiding surface 112. The clamping portion 11 is disposed outside the edge of the top plate 221 and the clamping block 111 abuts against the side wall 222 of the moving member 2, that is, the clamping portion 11 abuts and fits against the outer side wall of the inner housing 22. Continuously apply pressure to the moving member 2 until the top plate 221 abuts against the abutting portion 13, and then rotate the moving member 2 left and right so that the stopping surface 113 abuts against the inner wall surface of the card slot 21. Specifically, when the top plate 221 abuts against the abutting portion 13, the plane where the multiple clamping blocks 111 are located coincides with the plane where the multiple card slots 21 are located. Rotate the moving member 2 left and right. When hearing a "click" sound, the clamping block 111 is limited and received in the card slot 21, achieving the positioning installation between the fixing member 1 and the moving member 2.

[0064] When the clamping block 111 is received and limited in the clamping groove 21, part of the guiding strip 114 is received in the clamping groove 21, that is, the connection part between the guiding strip 114 and the clamping block 111 is received in the clamping groove 21, and the free end of the guiding strip 114 is placed outside the clamping groove 21 (that is, the end of the guiding strip 114 away from the clamping block 111 is far away from the clamping groove 21), a rotational force is applied to the moving part 2, so that the free end of the guiding strip 114 abuts against the edge of the clamping groove 21, and the rotational force is continuously applied to the moving part 2, and the edge of the clamping groove 21 moves along the inclined surface of the guiding strip 114 until the clamping block 111 leaves the clamping groove 21, so as to realize the quick disassembly between the fixing part 1 and the moving part 2.

[0065] In other embodiments, when the clamping groove 21 is arranged on the outer housing 23, the clamping block 111 extends from the clamping portion 11 in a direction away from the central axis of the fixing part 1, the clamping groove 21 is opened on the inner side wall of the outer housing 23, and during connection, the clamping portion 11 abuts against the inner side wall of the outer housing 23, and a pressure is applied to the moving part 2, so as to realize the disassembly and installation between the fixing part 1 and the moving part 2, and further realize the tool-free maintenance between the fixing part 1 and the moving part 2.

[0066] In this embodiment, both the fixing part 1 and the moving part 2 are cylindrically arranged, so that after the fixing part 1 and the moving part 2 are abutted, the moving part 2 can rotate relative to the fixing part 1, so as to realize the positioning installation of the moving part 2 and the fixing part 1 through the connecting device. Of course, in other embodiments, the shapes of the fixing part 1 and the moving part 2 can also be set according to actual situations. For example: they can be set as square, oval, polygon, etc., as long as the moving part 2 can rotate relative to the fixing part 1, and no limitation is made here.

[0067] Generally speaking, during installation, first, the installation part is passed through the installation hole 121 and fixedly connected to the installation surface. Subsequently, the moving part 2 is aligned with the fixing part 1, and a pressure towards the installation surface is applied to the moving part 2. By moving the edge of the top plate 221 along the guiding surface 112, the clamping portion 11 is attached to the side wall 222 of the inner housing 22 and received in the receiving groove 24. By continuously applying pressure, the top plate 221 of the moving part 2 abuts against the boss 132 of the fixing part 1, realizing the limitation of the moving part 2 by the fixing part 1. At the same time, the planes where the plurality of clamping blocks 111 are located coincide with the planes where the plurality of clamping grooves 21 are located. Finally, the moving part 2 is rotated so that the top plate 221 abuts against the boss 132 and rotates relative to the boss 132 until the clamping block 111 is received and limited in the clamping groove 21, and the stopping surface 113 abuts against the inner side wall of the clamping groove 21, realizing the installation guiding of the moving part 2.

[0068] In this application, the specific structure of the light-emitting module 300 and the connection structure between the light-emitting module 300 and the inner housing 22 can be set according to the prior art and will not be described in detail here. This specification only describes the general connection relationship between the light-emitting module 300 and the inner housing 22, specifically: a wire passing hole 2211 is formed in the top plate 221 of the inner housing 22. The light-emitting module 300 includes an LED lamp (not shown), a control component (not shown), and a light-transmitting cover 3. Among them, the LED lamp is connected to the control component, and the control component is connected to an external power supply through the wire passing hole 2211 and the through hole 122 to supply power to the light-emitting module 300. The control component is received in the receiving cavity 223 and connected to the top plate 221 of the inner housing 22. The light-transmitting cover 3 is connected to one end of the inner housing 22 away from the fixing plate 12 to shield and seal the receiving cavity 223. The light emitted by the LED lamp in the receiving cavity 223 passes through the light-transmitting cover 3 and is emitted to the outside.

[0069] In summary, the installation structure 200 of the present invention realizes the installation guidance of the moving member 2 by the abutting portion 13 of the fixing member 1 abutting against the top plate 221 of the moving member 2; by evenly distributing the four abutting portions 13 on the fixing plate 12, the problem of different depths during the assembly of the moving member 2 is avoided, so that the distance between the moving member 2 and the fixing member 1 is the same. At the same time, the mechanical balance between the moving member 2 and the fixing member 1 is realized; the abutting arm 131 is made of an elastic material and is arc-shaped, so that when the top plate 221 abuts against the abutting portion 13, elastic deformation can occur to avoid the fracture of the abutting arm 131 and extend the service life of the fixing member 1; by providing a boss 132 on the abutting portion 13 and the boss 132 abutting against the top plate 221, the moving member 2 can rotate smoothly relative to the fixing member 1, improving the installation satisfaction of the user.

[0070] Further, a plurality of clamping portions 11 are abutted against the outer side wall of the inner housing 22 to realize the elastic connection between the moving member 2 and the fixing member 1; by providing a guiding surface 112 on the clamping block 111, when the clamping portion 11 abuts against the edge of the inner housing 22, the edge of the inner housing 22 can move along the guiding surface 112 to realize the abutment of the clamping portion 11 against the side wall 222 of the inner housing 22; by providing a clamping block 111 on the clamping portion 11 and a stop surface 113 on the clamping block 111, and at the same time, a clamping groove 21 is formed on the side wall 222 of the inner housing 22, so that the clamping block 111 can be limited and received in the clamping groove 21, and the stop surface 113 abuts against the inner wall surface of the clamping groove 21 to realize the positioning installation between the fixing member 1 and the moving member 2; by providing a guiding strip 114 on the clamping block 111 and the free end of the guiding strip 114 is not received in the clamping groove 21, when the moving member 2 is rotated, the clamping block 111 can smoothly leave the clamping groove 21 to realize the quick disassembly between the fixing member 1 and the moving member 2.
