It can be understood that by providing the first snap-fit ​​strip 120 extending axially along the first through hole 110 on the hole wall of the first through hole 110, the contact area between the elastic retaining ring and the hole wall of the first through hole 110 is increased, thereby enhancing the connection strength between the main body 100 and the mounting bracket 200.

[0035] like Figure 4 As shown, in some embodiments, multiple first snap-fit ​​strips 120 are provided at circumferential intervals along the first through hole 110. It can be understood that by providing multiple first snap-fit ​​strips 120 at circumferential intervals along the first through hole 110, the contact area between the first through hole 110 and the elastic retaining ring in the circumferential direction can be further increased, thereby further enhancing the connection strength between the main body 100 and the mounting bracket 200.

[0036] like Figure 4As shown, in some embodiments, the first snap-fit ​​strip 120 has a guide surface 121 on the side near the base 210. The guide surface 121 is used to slide with the first positioning post 220 to guide the first positioning post 220 into the first through hole 110. It can be understood that by providing the guide surface 121 on the side of the first snap-fit ​​strip 120 near the base 210, when the user needs to install the main body 100 on the mounting bracket 200, the guide surface 121 can guide the first positioning post 220 to smoothly pass through the first through hole 110 when the first positioning post 220 passes through the first through hole 110.

[0037] In a further embodiment of this utility model, the first positioning post 220 has a circumferentially inclined surface 222 at the end opposite to the seat body 210, which is inclined toward the seat body 210. It can be understood that by providing the inclined surface 222 on the first positioning post 220, the first positioning post 220 can be guided to pass through the first insertion hole 110.

[0038] refer to Figure 2 In some embodiments of this utility model, the first positioning post 220 has a plurality of annular grooves 221 on its circumferential surface. The plurality of annular grooves 221 are distributed at intervals along the axial direction of the first positioning post 220, and an elastic retaining ring is installed in each annular groove 221. It can be understood that by fitting a plurality of elastic retaining rings on the first positioning post 220, the connection strength between the first positioning post 220 and the main body 100 can be further increased.

[0039] refer to Figure 2 In some embodiments of this utility model, the first positioning post 220 is detachably connected to the base 210. It is understood that by detachably connecting the first positioning post 220 to the base 210, it is convenient to manufacture and easy to replace when the first positioning post 220 is damaged.

[0040] In a specific embodiment of this utility model, a cross groove is provided on the end face of the first positioning post 220 facing away from the base 210, and the first positioning post 220 is threadedly connected to the base 210. It is understood that when it is necessary to disassemble or install the first positioning post 220, the user can use a Phillips screwdriver to unscrew the first positioning post 220 to separate or connect it to the base 210, making the operation simpler and more convenient.

[0041] refer to Figure 2 In some embodiments of this utility model, the mounting bracket 200 further includes a base 240, and the seat body 210 is hinged to the base 240. It is understood that by hinged to the base 240, the main body 100 can rotate relative to the base 240, thereby adjusting the angle of the seat body 210 of the main body 100 relative to the base 240.

[0042] Specifically, the seat 210 is rotatably mounted on the base 240 about a horizontal axis.

[0043] In some embodiments of this utility model, two sets of first positioning posts 220 and base bodies 210 are provided along the axial direction of the horizontal rotation axis, and two sets of first positioning posts 220 are provided on the main body 100. It can be understood that by providing two sets of first positioning posts 220 and base bodies 210, the connection stability between the main body 100 and the base 240 can be increased.

[0044] like Figure 2 and Figure 5 As shown, in some embodiments, one of the base 240 and the seat 210 is provided with a limiting protrusion 241, and the other is provided with an arc-shaped groove 211. The arc-shaped groove 211 extends circumferentially along the rotation axis of the seat 210, and the limiting protrusion 241 is slidably inserted into the arc-shaped groove 211 along the extension direction of the arc-shaped groove 211. It can be understood that by providing the limiting protrusion 241 and the arc-shaped groove 211, when the seat 210 rotates a certain angle relative to the base 240 in the forward direction, the limiting protrusion 241 abuts against one end of the arc-shaped groove 211 to limit its continued forward rotation. When the seat 210 rotates a certain angle relative to the base 240 in the reverse direction, the limiting protrusion 241 abuts against the other end of the arc-shaped groove 211 to limit its continued reverse rotation, thereby limiting the rotation angle of the seat 210 relative to the base 240.

[0045] Specifically, the base 240 is provided with a limiting protrusion 241, and the seat 210 is provided with an arc-shaped groove 211.

[0046] refer to Figure 2 In some embodiments of this utility model, the mounting bracket 200 further includes a second positioning post 230, and a second through hole 130 is provided on the main body 100. One end of the second positioning post 230 is connected to the base 210, and the other end of the second positioning post 230 is engaged with the wall of the second through hole 130. It can be understood that by setting the second positioning post 230 to engage with the wall of the second through hole 130, the connection stability between the main body 100 and the mounting bracket 200 can be further enhanced.

[0047] In some embodiments of this utility model, the diameter of the first positioning post 220 is larger than the diameter of the second positioning post 230. It can be understood that the main body 100 is positioned by setting the diameter of the second positioning post 230 to be smaller than the diameter of the first positioning post 220.

[0048] like Figure 4As shown, in some embodiments, the wall of the second through hole 130 is formed with a second snap-fit ​​strip 140 extending axially along the second through hole 130, and the second snap-fit ​​strip 140 abuts against the second positioning post 230. It can be understood that by providing the second snap-fit ​​strip 140 on the wall of the second through hole 130, the connection strength between the second positioning post 230 and the body 100 can be increased.

[0049] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
