The wave-shaped spring sheet is disposed between the first rod and the second rod. The wave-shaped spring sheet has crests and troughs, at least one of the troughs is fixed to the first rod, and the crests are arched relative to the first rod. The wave-shaped spring sheet has a deformation section extending along its length direction. The deformation section is the interval from the edge of the wave-shaped spring sheet to the nearest trough for fixed connection with the first rod. The deformation section is not fixed to the first rod so that it can be deformed by compression and extends along its length direction. The crests in the deformation section are compressed by the second rod to generate a preload force when the two rods slide relative to each other.
[0007] In one embodiment, the trough fixed to the first rod is a fixed trough, and the number of fixed troughs is one. The deformation segment includes a first deformation segment and a second deformation segment connected to opposite sides of the fixed trough.

[0008] In one embodiment, one of the first deformation segment and the second deformation segment has a hanging platform at the end away from the fixed trough, the hanging platform being perpendicular to the length extension direction of the deformation segment, and the hanging platform overlapping one end face of the first rod body.
[0009] In one embodiment, the second rod body has a first slide rail extending axially on the side facing the first rod body. The first slide rail allows the wave spring to slide and limit one end of the first rod body, and the wave crest abuts against the inner wall of the first slide rail.

[0012] In one embodiment, there are two wave springs, one first rod is sandwiched between the two wave springs, and two second rods and one first slide rail are connected radially to each other, and the two first slide rails enclose each other to form a circumferentially closed state, so that the first rod is fitted inside the two second rods.
[0013] In one embodiment, the first rod body is provided with a second slide rail along its axial direction on the side facing the second rod body, the wave spring is fixed to the inner wall of the end of the second slide rail, the second slide rail is used for limiting the sliding of the beginning of the second rod body, and the wave crest abuts against the outer wall of the second rod body.
[0014] In one embodiment, the inner sidewall of the starting end of the second slide rail is provided with a protruding third blocking part, the third blocking part extends along the vertical telescopic direction, the starting end of the second rod moves to abut against the third blocking part, and the telescopic rod structure is shortened to its minimum length;
[0015] And / or, the starting end of the second rod body is provided with a protruding fourth blocking part facing the outer wall of the second slide rail. The fourth blocking part extends in the vertical telescopic direction.

[0017] Second aspect
[0018] This application provides a selfie device, comprising:
[0019] A mounting part for mounting shooting equipment, wherein the mounting part is a magnetic ring or a telescopic clamp; and,
[0020] As described in any of the preceding embodiments, in the telescopic rod structure, one of the first rod body and the second rod body is connected to the mounting part, and the other is provided for the user to hold.
[0021] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

The selfie device flexibly adjusts the shooting distance and orientation of the shooting device through the telescopic rod structure. The telescopic rod structure includes a first rod, a second rod, and a wave-shaped spring. Because the wave-shaped spring deforms along its length, the user only needs to pull one of the rods (either the first or the second rod) slightly to extend or retract the telescopic rod structure. When pulling stops, the crest of the wave-shaped spring provides stable damping for the target usable length of the telescopic rod structure. Compared to traditional telescopic structures that lock the handle length using screws or threaded rotation, the telescopic rod structure of this application does not require additional parts or external force to lock the length. It is simple in structure, convenient to operate, and greatly improves the user's feel and operating experience. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0038] Reference Figure 1-3 This application provides a novel telescopic rod structure 10, including a first rod body 100, a second rod body 200, and a wave spring 300. The first rod body 100 and the second rod body 200 are slidably connected to realize the extension or shortening of the telescopic rod structure 10. The wave spring 300 is disposed between the first rod body 100 and the second rod body 200. The wave spring 300 has a crest 310 and a trough 320. At least one trough 320 (fixed trough 321) is fixed to the first rod body 100, and the crest 310 is arched relative to the first rod body 100. The wave spring 300 has a deformation segment 330 extending along its length. The deformation segment 330 is the range from the edge of the wave spring 300 to the nearest trough 320 for fixed connection with the first rod 100. The deformation segment 330 is not fixedly connected to the first rod 100 so that it can be deformed by compression and elongates along its length. The crest 310 in the deformation segment 330 is compressed by the second rod 200 to generate a preload force when the two rods (first rod 100 and second rod 200) slide relative to each other. This preload force acts as sliding damping to maintain the total length of the two rods in contact, i.e., the length dimension of the entire telescopic rod structure 10. Here, the wave spring 300 has elastic deformation, which occurs by changing its length by compressing the crest in the wave shape.
[0039] Preferred, combined Figure 2 and Figure 3In one embodiment, the trough 320 fixed to the first rod 100 is defined as a fixed trough 321, meaning that only one trough 320 in the wave spring 300 is fixed to the first rod 100. The deformation segment 330 includes a first deformation segment 331 and a second deformation segment 332 connected to opposite sides of the fixed trough 321. The number of wave peaks 310 in the first deformation segment 331 is equal to the number of wave peaks 310 in the second deformation segment 332, so that the deformation force of the wave spring 300 extending from the fixed trough 321 to both sides is relatively balanced. It should be noted that because the wave spring 300 has high rigidity, if multiple troughs 320 are fixed to the first rod 100 (i.e., multiple fixed troughs 321), the wave peaks 310 between adjacent fixed troughs 321 are always under compression, making the wave spring 300 prone to breakage and damage. Therefore, the setting of a fixed trough 321 largely protects the entire wave spring 300 and extends its service life. It should be understood that, without considering the protection of the entire waveform spring 300 and its force balance, in this application, the number of fixed troughs 321 is not limited, and the number of peaks 310 set on the first deformation segment 331 and the second deformation segment 332 is not limited. They can be equal or unequal, or even only one deformation segment 330 can be set.
[0040] Preferably, in conjunction with reference Figure 2-4 In one embodiment, one of the first deformation segment 331 and the second deformation segment 332 has a mounting platform 340 at the end away from the fixed trough 321. The mounting platform 340 is perpendicular to the length extension direction of the deformation segment 330 and overlaps one end face of the first rod 100, so that the entire wave spring 300 is connected to the first rod 100 through the mounting platform 340 and the fixed trough 321. At least two connection positions can prevent the wave spring 300 from deflecting left or right during deformation, so as to maintain the wave spring 300 undergoing stable linear deformation along its length extension direction, thereby improving the smoothness of sliding extension and contraction between the first rod 100 and the second rod 200. It should be noted that, without considering the prevention of left or right deflection of the wave spring 300, the presence or absence of the mounting platform 340 is not limited in this application.
[0041] Preferably, in conjunction with reference Figure 4 and Figure 5In one embodiment, the second rod 200 has a first slide rail 210 extending axially on its side facing the first rod 100. The first slide rail 210 provides a limiting sliding mechanism between the wave spring 300 and one end of the first rod 100. The wave crest 310 arches relative to the outer wall of the first rod 100 and abuts against the inner wall of the first slide rail 210. Here, the first slide rail 210 provides a limiting function, which can prevent the wave spring 300 and the first rod 100 from shifting left and right during sliding extension and retraction relative to the second rod 200, thereby improving the linear sliding stability of the first rod 100 along its axial direction. It should be noted that, without considering the sliding stability of the first rod 100, the presence or absence of the first slide rail 210 is not limited in this application.
[0042] Preferably, in conjunction with reference Figure 4 and Figure 5 In one embodiment, the first slide rail 210 has a protruding first blocking part 220 at its starting end. The first blocking part 220 extends perpendicular to the telescopic direction. When the first rod 100 slides relative to the second rod 200, the wave spring 300 moves to abut against the first blocking part 220, and the telescopic rod structure 10 shortens to its minimum length. Figure 4 As shown in the figure, the first blocking part 220 is used to prevent the first rod 100 from shortening excessively and penetrating the second rod 200 along its axial direction, thus providing a reminder function to the user. And / or, as illustrated in the figure, the inner wall of the end of the first slide rail 210 is provided with a protruding second blocking part 230. The second blocking part 230 extends perpendicular to the telescopic direction. When the first rod 100 slides relative to the second rod 200, the wave-shaped spring 300 moves to abut against the second blocking part 230 to restrict the first rod 100 from moving away from the first slide rail 210, preventing the first rod 100 from separating from the second rod 200. At this time, the telescopic rod structure 10 extends to its maximum length. Figure 5 As shown in the diagram, the second blocking part 230 serves to prevent detachment. The first blocking part 220 or the second blocking part 230 is implemented using methods such as screws 221 or protruding structures. It should be noted that the presence or absence of the first blocking part 220 or the second blocking part 230 is not limited, provided that the user applies appropriate force using the telescopic rod structure 10.
[0043] Preferably, in one embodiment, in conjunction with reference to Figure 2 and Figure 4The system comprises two wave-shaped spring pieces 300 and one first rod 100 sandwiched between the two wave-shaped spring pieces 300. There are also two second rods 200 and corresponding first slide rails 210. The two second rods 200 are radially interlocked, and the two first slide rails 210 form a circumferentially closed state, allowing the first rod 100 to be fitted inside the two second rods 200, forming a sleeved telescopic rod structure 10. The telescopic rod structure 10 is symmetrically arranged relative to the first rod 100. Optionally, the two second rods 200 can be integrally formed with an interlocking structure. The two wave-shaped spring pieces 300 make the internal structure of the telescopic rod structure 10 compact and the force evenly distributed, greatly improving the stability of the sliding connection. It should be noted that, without considering the overall compactness or internal force balance of the telescopic rod structure 10, the number of second rods 200 and whether the telescopic rod structure 10 is sleeved are not limited.
[0044] It should be noted that the first rod 100 and the second rod 200 are relatively slidably connected. The slide rail can be set on the second rod 200 or on the first rod 100. For ease of distinction, the slide rail set on the second rod 200 is defined as the first slide rail 210, and the slide rail set on the first rod 100 is defined as the second slide rail (not shown in the figure).
[0045] Similarly, in another embodiment, the first rod 100 has a second slide rail along its axial direction on the side facing the second rod 200. The wave spring 300 is fixed to the inner wall of the end of the second slide rail. The second slide rail provides a limiting sliding for the beginning of the second rod 200, and the wave crest 310 arches relative to the inner side of the second slide rail and abuts against the outer wall of the second rod 200. Here, the second slide rail provides a limiting function, which can prevent the wave spring 300 and the first rod 100 from shifting left and right during the sliding extension and retraction relative to the second rod 200, thereby improving the linear sliding stability of the first rod 100 along its axial direction.
[0046] Furthermore, the inner sidewall of the starting end of the second slide rail is provided with a protruding third blocking part, which extends perpendicular to the telescopic direction. When the first rod 100 slides relative to the second rod 200, the starting end of the second rod 200 moves to abut against the third blocking part, and the telescopic rod structure 10 shortens to its minimum length. And / or, the starting end of the second rod 200 is provided with a protruding fourth blocking part facing the outer sidewall of the second slide rail, which extends perpendicular to the telescopic direction. The second rod 200 moves until the fourth blocking part abuts against the wave-shaped spring sheet to restrict the second rod 200 from sliding off the second slide rail, thereby preventing the second rod 200 from separating from the second rod.
[0047] Furthermore, there is one wave spring 300, one second rod 200 sandwiched between two wave springs 300, and two first rods 100 and two second slide rails. The two first rods 100 are connected radially, and the two second slide rails enclose each other to form a circumferential closed state, so that the second rod 200 is fitted inside the two first rods 100.
[0048] Second aspect
[0049] Reference Figure 6 and Figure 7 This application provides a selfie device 1, including a mounting part 20 and a telescopic rod structure 10. The mounting part 20 is used to mount a shooting device. One of the first rod 100 and the second rod 200 in the telescopic rod structure 10 is connected to the mounting part 20, while the other is held by the user. In this application, the second rod 200 is fixedly connected to the mounting part 20, and the first rod 100 can extend or retract relative to the mounting part 20. Optionally, the mounting part 20 is a magnetic ring 21, or it is a telescopic clamp. The shooting device includes, but is not limited to, mobile phones, tablets, and small cameras.
[0050] This utility model provides a telescopic rod structure 10 and a selfie device 1. The selfie device 1 flexibly adjusts the shooting distance and orientation of the shooting device through the telescopic rod structure 10. The telescopic rod structure 10 includes a first rod 100, a second rod 200, and a wave spring 300. Because the wave spring 300 deforms along its length, the user only needs to pull one of the rods (either the first rod 100 or the second rod 200) slightly to extend or retract the telescopic rod structure 10. When pulling stops, the crest 310 of the wave spring 300 arches to provide stable damping for the target length of the telescopic rod structure 10. Compared to traditional telescopic structures that lock length using screws or threaded rotation, the telescopic rod structure 10 of this application does not require additional parts or external force to lock the length. It has a simple structure, is easy to operate, and greatly improves the user's feel and operating experience.
