Description

Technical Field

[0001] The present invention relates to the technical field of VR glasses, and specifically to a rotating shaft structure of VR glasses. Background Art

[0002] As is well known, a VR glasses, a virtual reality head-mounted display device, uses the head-mounted display device to close a person's vision and hearing to the outside world, guiding the user to have a feeling of being in a virtual environment. Its display principle is that the left and right eye screens respectively display the images of the left and right eyes. After the human eye obtains this different information, a three-dimensional sense is generated in the mind.

[0003] For example, in the patent with the publication number CN212781499U and the publication date of March 23, 2021, it discloses a VR glasses leg and glasses. The VR glasses leg includes: a glasses leg and a glasses leg sleeve. The glasses leg includes a frame connection component for connecting the glasses leg to the glasses main body and a main rod of the glasses leg for supporting the glasses main body. The glasses leg sleeve is sleeved on the surface of the main rod of the glasses leg to form a buffer between the glasses leg and the ear and cheek during wearing. The glasses leg sleeve is provided to fully cover the surface of the main rod of the glasses leg in contact with the ear and cheek, forming a buffer between the glasses leg and the ear and cheek during wearing, and improving the comfort of the user during wearing. On the other hand, the present invention provides a VR glasses, including a glasses main body and a VR glasses leg. The glasses main body includes a glasses frame and a glasses leg connection component for connecting the glasses leg. The glasses leg connection component is detachably connected to the frame connection component, so that the glasses leg is fixed on the glasses main body. The replacement of the glasses leg is realized, and glasses legs of different sizes meet the needs of different users, improving the user experience of using VR glasses.

[0004] The disadvantages of the prior art are that when wearing a VR glasses composed of a glasses frame and glasses legs, it is necessary to adjust the angle between the glasses legs and the glasses frame to make the wearer wear comfortably. After adjusting the angle between the glasses legs and the glasses frame, there is no limiting structure provided to maintain the included angle between the glasses frame and the glasses legs basically unchanged. Then, the glasses frame and the glasses legs after adjusting the included angle can still deflect respectively with the rotating shaft structure, so that the VR glasses will fall off during wearing. Summary of the Invention

[0005] The purpose of the present invention is to provide a rotating shaft structure of VR glasses to solve the technical problems in the related art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A VR glasses rotating shaft structure includes a first connecting portion connected to the frame and a second connecting portion connected to the temple. A shaft rod is fixedly connected to the first connecting portion, and the second connecting portion is rotatably connected to the shaft rod. A limiting member is also included; after adjusting the angle between the frame and the temple, the limiting member restricts deflection between the frame and the temple.

[0008] In the above, the limiting member includes a plate body. One end of the plate body is connected to the frame, and the other end is connected to the temple. When adjusting the angle between the frame and the temple, the plate body undergoes plastic deformation to maintain the angle between the frame and the temple unchanged.

[0009] In the above, the limiting member includes a nut screwed to the end of the shaft rod. A first limiting block is slidably arranged on the shaft rod along the axial direction, and a first elastic member is connected between the nut and the first limiting block. A second limiting block is fixedly connected to the second connecting portion, and the first limiting block and the second limiting block are arranged side by side in the same axial direction; under the elastic force of the first elastic member, the first limiting block and the second limiting block restrict each other when rotating circumferentially.

[0010] In the above, two adjacent end faces of the first limiting block and the second limiting block are both wavy with uneven circumferential surfaces, and the two adjacent end faces of the first limiting block and the second limiting block are in concave-convex mating contact.

[0011] In the above, a ring body is provided at one end of the first elastic member in contact with the first limiting block. An annular groove for the ring body to slide axially is formed on the first limiting block, and an adjusting mechanism is provided on the shaft rod; when it is necessary to adjust the angle between the temple and the frame, the adjusting mechanism drives the ring body closer to the second limiting block to reduce the elastic force of the first elastic member on the first limiting block when rotating; after the angle between the temple and the frame is adjusted, the adjusting mechanism drives the ring body away from the second limiting block to increase the elastic force of the first elastic member on the first limiting block when rotating.

[0012] In the above, the adjusting mechanism includes a rod body movably arranged on the shaft rod. A first block is provided at the lower end of the rod body. A plurality of support rods are sequentially hinged on the circumference of the first block. A first slot is formed on the inner wall of the annular groove. The support rods have two positions in the annular groove: the first position, the support rods are inserted into the corresponding first slots, and at this time the support rods support the ring body so that the first elastic member gives the maximum elastic force to the first limiting block; the second position, the rod body rotates to drive the support rods to disengage from the corresponding first slots, and the rod body moves axially to drive the support rods away from the first slots, and at this time the support rods support the ring body so that the first elastic member gives the minimum elastic force to the first limiting block.

[0013] As described above, a plurality of the first slots are sequentially arranged along the axial direction on the inner wall of the annular slot.

[0014] As described above, the rod body is slidably connected to the first block body in the axial direction, and a second elastic member is connected between the rod body and the shaft rod in the sliding direction. A second block body is fixedly connected to one end of the support rod close to the first block body. A plurality of second slots are sequentially formed in the rod body along the axial direction. When the rod body rotates to drive the support rod out of the insertion stroke of the first slot, the support rod swings on the first block body to drive the second block body into the second slot at the corresponding position.

[0015] As described above, the adjacent positions of two adjacent first slots are rounded structures, the adjacent positions of two adjacent second slots are rounded structures, and the positions of the plurality of first slots and the plurality of second slots correspond one by one.

[0016] As described above, the spring constant of the first elastic member is greater than the spring constant of the second elastic member.

[0017] The beneficial effect of the present invention is that by providing a limiting member, it is possible to limit the frames after adjusting the included angle, so as to basically ensure that during the wearing process of the VR glasses, the frames and the temple legs do not deflect around the shaft rod as the rotation axis, resulting in the problem of falling off.

Detailed implementation manners

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following will further introduce the present invention in detail in conjunction with the attached Figure 1 to the attached Figure 8 drawings.

[0030] Refer to Figure 1 and Figure 2 . A rotating shaft structure of a VR glasses provided by an embodiment of the present invention includes a first connecting portion 30 connected to the spectacle frame 1 and a second connecting portion 31 connected to the temple 2. A shaft rod 32 is fixedly connected to the first connecting portion 30, and the second connecting portion 31 is rotatably connected to the shaft rod 32. The structure further includes a limiting member. After adjusting the angle between the spectacle frame 1 and the temple 2, the limiting member restricts the deflection between the spectacle frame 1 and the temple 2.

[0031] Specifically, the frame 1 and the lenses on the frame 1 are used to implement the video playback function of the VR glasses. A nose pad is provided thereon, and there are two temple arms 2. Each temple arm 2 corresponds to one ear of the wearer. When wearing the glasses, the frame 1 is supported by the wearer's nose through the nose pad, and the two ears correspondingly support the two temple arms 2, so as to wear the VR glasses on the head. The principle is that by setting two lenses corresponding to the two eyes of the wearer, the playback content is cut in half, and the images are superimposed through the lenses. The centers of the wearer's eye pupils, the centers of the lenses, and the centers of the screens (after splitting the screen) are on a straight line to obtain the best visual effect. Before obtaining the best visual effect, it should also make the wearer comfortable when wearing the VR glasses, that is, the sizes of the frame 1 and the temple arms 2 are designed in advance. Then, by adjusting the angle change between the frame 1 and each temple arm 2, each temple arm 2 can correspond to the corresponding ear, and the nose pad can correspond to the nose. The above is the prior art. In the prior art, after adjusting the angle between the temple arm 2 and the frame 1, there is no limiting structure to maintain the angle between the frame 1 and the temple arm 2 basically unchanged. Then, the frame 1 and the temple arm 2 after adjusting the angle can still deflect respectively with the rotating shaft structure 3. In this way, it will cause the problem of the VR glasses falling off when worn. Therefore, in this embodiment, by setting a limiting member, after adjusting the angle between the frame 1 and the temple arm 2, the deflection between the frame 1 and the temple arm 2 can be restricted. That is, the deflection between the frame 1 and the temple arm 2 is mainly realized by the rotating shaft structure 3. Then, if it is necessary to restrict the angle between the temple arm 2 and the frame 1 after adjustment, it can start from the first connecting portion 30, the second connecting portion 31, and the shaft rod 32. For example, after adjusting the angle between the temple arm 2 and the frame 1, a bolt (not shown in the figure) is screwed onto the shaft rod 32, and the position of the bolt is on the rotation path of the second connecting portion 31 on the shaft rod 32. In this way, after the second connecting portion 31 is acted on by an external force, it cannot rotate on the shaft rod 32, so as to realize the positioning of the temple arm 2 and the frame 1; or a nut is provided on the shaft rod 32. When it is necessary to normally adjust the angle between the temple arm 2 and the frame 1, the nut does not contact the second connecting portion 31 at this time. After the angle between the temple arm 2 and the frame 1 is adjusted, the nut is screwed to move axially to closely adhere to the second connecting portion 31, and the second connecting portion 31 is pressed axially, so that the nut, the second connecting portion 31, and the first connecting portion 30 are abutted in sequence. In this way, the normal pressure on the contact surface between the second connecting portion 31 and the first connecting portion 30 becomes larger, and the frictional force between the two also increases accordingly, so as to realize the limiting effect on the positions of the frame 1 and the temple arm 2.

[0032] The beneficial effect of this embodiment is that by setting a limiting member, it is possible to restrict the frame 1 and the frame 1 after adjusting the angle, so as to basically ensure that during the wearing process of the VR glasses, the frame 1 and the temple arm 2 do not deflect around the shaft rod 32 to cause the problem of falling off.

[0033] Preferably, the limiting member includes a plate body 4, one end of the plate body 4 is connected to the spectacle frame 1, and the other end is connected to the temple 2. When adjusting the angle between the spectacle frame 1 and the temple 2, the plate body 4 undergoes plastic deformation to maintain the angle between the spectacle frame 1 and the temple 2 unchanged.

[0034] Specifically, in the foregoing embodiment, whether it is to use a bolt to limit the rotation path of the second connecting portion 31 or to apply pressure to the second connecting portion 31 axially through a nut 5, this undoubtedly brings relatively difficult operations to the adjustment of the angle between the temple 2 and the spectacle frame 1. That is, the tightening and loosening of the bolt require tools, and the tightening and loosening of the nut 5 also require tools. Therefore, in this embodiment, by providing the plate body 4, the plate body 4 can undergo plastic deformation. That is, when subjected to an external force, the plate body 4 will stop at the angle where it bends and will not rebound. For example, a thin metal plate can be regarded as capable of plastic deformation. The length of the plate body 4 is much greater than the width. One end of it is connected to the spectacle frame 1, and the other end is connected to the temple 2. The middle part thereof passes through the shaft rod 32. The part of the plate body 4 at the shaft rod 32 is in an arc shape (this is the first arc portion 40) and wraps around the outside of the shaft rod 32, and does not hinder the rotation of the second connecting portion 31 on the shaft rod 32. The part of the plate body 4 between the first arc portion 40 and the spectacle frame 1 is in an arc shape (this is the second arc portion 41) with the opening opposite to that of the first arc portion 40. When the angle between the spectacle frame 1 and the temple 2 changes, the deformed part of the plate body 4 is the second arc portion 41. When the plate body 4 deforms, the straight-line distance between the two ends changes, that is, the ends of the plate body 4 need to move to adapt to the deformation. The first arc portion 40 cannot affect the rotation of the second connecting portion 31 on the shaft rod 32. Therefore, the connection between the plate body 4 and the spectacle frame 1 is a movable connection, that is, the end of the plate body 4 can slide on the spectacle frame 1 along its own length direction, that is, at least one end of the end of the plate body 4 is not fixed, but only fits or sleeved on the spectacle frame 1 and / or the temple 2.

[0035] Refer to Figure 3 and Figure 8 As shown, in another embodiment of the present invention, the limiting member includes a nut 5 screwed to the end of the shaft rod 32. A first limiting block 6 is slidably arranged on the shaft rod 32 along the axial direction, and a first elastic member 60 is connected between the nut 5 and the first limiting block 6. A second limiting block 7 is fixedly connected to the second connecting portion 31. The first limiting block 6 and the second limiting block 7 are arranged side by side in the same axial direction, that is, they are in contact with each other; under the elastic force of the first elastic member 60, the first limiting block 6 and the second limiting block 7 limit each other when rotating circumferentially.

[0036] Specifically, the first limit block 6 is cylindrical and is slidably sleeved on the shaft rod 32 along the axial direction of the shaft rod 32, that is, the outer wall of the shaft rod 32 is not a complete circle from the radial cross section, and is a non-rotating body. It is preferably a combination of an arc segment and a straight line segment. The inner wall of the first limit block 6 can adapt to the outer wall shape of the shaft rod 32, so that the rotation of the shaft rod 32 can drive the first limit block 6 to rotate synchronously, and when the first limit block 6 is subjected to an axial force, it can slide on the shaft rod 32 without driving the shaft rod 32 to move together. The nut 5 is threadedly connected to one end of the shaft rod 32, which can limit the first elastic member 60 and the first limit block 6 from disengaging from the shaft rod 32. The other end of the shaft rod 32 is fixed to the first connecting portion 30. The second limit block 7 is coaxial with the first limit block 6, that is, the second limit block 7 is also sleeved on the outer wall of the shaft rod 32, but the inner wall of the second limit block 7 The radial cross-section of the wall is a complete circle, that is, the axial movement and circumferential rotation of the second limit block 7 will not drive the shaft 32 to move together. The second limit block 7 is fixedly connected to the second connecting portion 31, and the elastic force of the first elastic member 60 provides positive pressure for the first limit block 6 to squeeze the second limit block 7 in the axial direction. Therefore, the first limit member and the second limit member can limit the rotation of each other through friction. Therefore, when adjusting the angle between the temple 2 and the frame 1, the wearer can manually bend the temple 2 with one hand and control the frame 1 with the other hand to keep it still, so as to overcome the mutual friction between the first limit block 6 and the second limit block 7. After the angle between the temple 2 and the frame 1 is adjusted, the mutual friction between the first limit block 6 and the second limit block 7 can ensure that the adjusted positions of the frame 1 and the temple 2 will basically not change when no external force is applied.

[0037] Preferably, the two adjacent end surfaces of the first limiting block 6 and the second limiting block 7 are both in an uneven annular wave shape along the circumferential direction, and the two adjacent end surfaces of the first limiting block 6 and the second limiting block 7 are in concave-convex fitting contact.

[0038] Specifically, in the aforementioned embodiments, whether it is by setting the plate body 4 and utilizing its plastic deformation to position the temple 2 and the frame 1 after the angle is adjusted, or by setting the first limit block 6 and the second limit block 7 and utilizing the mutual friction between the two to position the temple 2 and the frame 1 after the angle is adjusted, there will be a problem, that is, the resistance that needs to be overcome to adjust the change of the angle between the frame 1 and the temple 2 and the subsequent limiting force on the temple 2 and the frame 1 after the angle is adjusted are consistent, and the resistance encountered does not change during the adjustment process, resulting in a low limiting effect after the angle between the frame 1 and the temple 2 is adjusted.

[0039] Therefore, in this embodiment, the two adjacent end faces of the first limit block 6 and the second limit block 7 are both arranged to be wavy and uneven along the circumferential direction, that is, the end face of the first limit block 6 is alternately arranged with inward concave and outward convex in the circumferential direction, and the end face of the second limit block 7 is alternately arranged with outward convex and inward concave in the circumferential direction. When the first limit block 6 and the second limit block 7 rotate to restrict each other in the circumferential direction, the inward concave on the end face of the first limit block 6 is in cooperation with the outward convex on the end face of the second limit block 7, and the outward convex on the end face of the first limit block 6 is in cooperation with the inward concave on the end face of the second limit block 7. When the convex part on the end face of the first limit block 6 disengages from the concave part on the second limit block 7 and moves to the convex part, since the second limit block 7 cannot move in the axial direction, the first limit block 6 is squeezed and moves in the axial direction to squeeze the first elastic member 60, so that the elastic force of the first elastic member 60 becomes larger. Therefore, when the angle between the temple 2 and the frame 1 needs to be changed, a gradually increasing external force needs to be provided. Compared with the aforementioned method of limiting the position of the temple 2 and the frame 1 after adjusting the angle, the method provided in this embodiment is more suitable.

[0040] Furthermore, a ring body 61 is provided at one end of the first elastic member 60 that contacts the first limit block 6, and an annular groove 62 is provided on the first limit block 6 for the ring body 61 to slide axially, and an adjustment mechanism is provided on the shaft rod 32; when it is necessary to adjust the angle between the temple 2 and the frame 1, the adjustment mechanism drives the ring body 61 to approach the second limit block 7 to reduce the elastic force of the first elastic member 60 on the first limit block 6 when it rotates; after the adjustment of the angle between the temple 2 and the frame 1 is completed, the adjustment mechanism drives the ring body 61 away from the second limit block 7 to increase the elastic force of the first elastic member 60 on the first limit block 6 when it rotates.

[0041] Specifically, in the aforementioned embodiment, a large force needs to be overcome to restrict the frame 1 and the temple 2 after adjusting the angle, which is beneficial to improving the effect of restricting the frame 1 and the temple 2. However, a large force needs to be overcome when adjusting the angle between the frame 1 and the temple 2, which is obviously inappropriate.

[0042] Therefore, in the present embodiment, an annular groove 62 is axially provided on the end face of the first limit block 6 away from the second limit block 7, a ring body 61 is slidably arranged in the annular groove 62, and the first elastic member 60 is fixedly connected to the ring body 61. During the stroke in which the elastic force of the first elastic member 60 decreases, the ring body 61 will be pushed to move in the annular groove 62 in the direction close to the second limit block 7. By setting an adjustment mechanism, when adjusting the included angle between the frame 1 and the temple 2, the elastic force of the first elastic member 60 is reduced, and when restricting the frame 1 and the temple 2 after the adjusted included angle, the elastic force of the first elastic member 60 is increased.

[0043] That is, in a preferred embodiment, the adjusting mechanism includes a rod body 63 movably arranged on the shaft rod 32. A first block body 64 is provided at the lower end of the rod body 63. A plurality of support rods 65 are sequentially hinged in the circumferential direction of the first block body 64. A first slot 66 is formed on the inner wall of the annular groove 62. The support rod 65 has two positions in the annular groove 62: the first position, the support rod 65 is inserted into the corresponding first slot 66. At this time, the support rod 65 supports the ring body 61 so that the first elastic member 60 exerts the maximum elastic force on the first limiting block 6; the second position, the rod body 63 rotates to drive the support rod 65 to disengage from the insertion into the corresponding first slot 66, and the rod body 63 moves axially to drive the support rod 65 away from the first slot 66. At this time, the support rod 65 supports the ring body 61 so that the first elastic member 60 exerts the minimum elastic force on the first limiting block 6.

[0044] That is, the radial cross-section of the rod body 63 is circular, and it can move axially and rotate circumferentially along the axial center line of the shaft rod 32. A first section is also provided on the shaft rod 32 for the first block 64 to move axially and rotate circumferentially. A number of support rods 65 are hinged circumferentially on the first block 64. Then, at the position on the shaft rod 32 corresponding to the first section (that is, the part of the shaft rod 32 within the first section), a second section is also provided for each support rod 65 to move axially and deflect at the hinge joint with the first block 64. The annular groove 62 communicates with each second section. Driving the rod body 63 to rotate circumferentially by an external force can drive each support rod 65 to move towards the center of the first block 64 through the first block 64. Driving the rod body 63 to move axially by an external force can drive each support rod 65 to move axially through the first block 64. Therefore, when adjusting the included angle between the spectacle frame 1 and the temple 2, it is necessary to reduce the elastic force of the first elastic member 60. After adjusting the included angle between the spectacle frame 1 and the temple 2, it is necessary to increase the elastic force of the first elastic member 60. That is, the support rod 65 has two positions in the annular groove 62: the first position, where the elastic force of the first elastic member 60 is the largest, that is, the support rod 65 is farthest from the second limiting block 7 axially within the first section, and a first slot 66 is provided on the inner wall of the annular groove 62 corresponding to this position. At this time, the included angle between two adjacent support rods 65 is 90 degrees. Then, the support rod 65 can be inserted into the corresponding first slot 66 to limit the ring body 61 from moving towards the second limiting block 7 under the elastic force of the first elastic member 60;The second position is the position where the elastic force of the first elastic member 60 is minimized. When it is necessary to reduce the elastic force of the first elastic member 60, first rotate the rod body 63. Drive each support rod 65 to approach the center of the first block 64 through the first block 64. During this process, the support rod 65 gradually disengages from the corresponding first slot 66. After the support rod 65 completely disengages from the first slot 66, push the rod body 63 axially in the direction close to the second block 68, that is, the support rod 65 moves to the second position. At this time, when adjusting the included angle between the temple 2 and the frame 1, it will be affected by the minimum elastic force of the first elastic member 60, that is, the support rod 65 is closest to the second limiting block 7 axially within the first interval. When the temple 2 and the frame 1 need position limitation after adjusting the included angle, drive the rod body 63 to move away from the second limiting block 7 until the support rod 65 is aligned with the corresponding first slot 66 in the radial direction. During this process, all the support rods 65 jointly push the ring body 61 to compress the first elastic member 60, so that the elastic force of the first elastic member 60 increases. Then rotate the rod body 63 in the reverse direction so that the support rod 65 is inserted into the corresponding first slot 66, then the elastic force of the first elastic member 60 is difficult to release, and the position of the temple 2 and the frame 1 can be better restricted. (In this embodiment, the maximum elastic force of the first elastic member 60 is used to form the restriction on the position of the temple 2 and the frame 1. Compared with the elastic force of the first elastic member 60 in the previous embodiment, the maximum elastic force of the first elastic member 60 in this embodiment is greater, and its restriction effect is much stronger than the elastic force of the first elastic member 60 in the previous embodiment).;

[0045] Further, a plurality of the first slots 66 are sequentially arranged axially on the inner wall of the annular groove 62; specifically, in the previous embodiment, when the elastic force of the first elastic member 60 is the largest, the position of the temple 2 and the frame 1 after adjusting the included angle is restricted. At this time, it is difficult to change the included angle between the temple 2 and the frame 1 by the action of an external force (the external force in the text refers to the force applied by the hand when the wearer manually adjusts the included angle between the temple 2 and the frame 1). However, for different wearers, the head size is different, and the relationship between the wearing tightness is related to the comfort of the wearer. The wearing comfort can be adjusted by adjusting the elastic force of the first elastic member 60 that restricts the position of the temple 2 and the frame 1, that is, a plurality of first slots 66 are axially opened on the inner wall of the annular groove 62. At this time, by driving the rod body 63 to move axially, the rod body 63 drives the block to move together, and the block drives all the support rods 65 to move together. Then the support rod 65 can be inserted into any first slot 66. In this way, the elastic force of the first elastic member 60 does not need to be adjusted to the maximum. In this way, while realizing the restriction of the position of the frame 1 and the temple 2, there can also be a certain range of elastic force change between the temple 2 and the frame 1 (specifically, refer to the concave-convex fit between the two end faces of the first limiting block 6 and the second limiting block 7 in the previous description) to improve the wearing comfort.

[0046] Further, the rod body 63 is slidably connected to the first block body 64 in the axial direction. In the sliding direction, a second elastic member 67 is connected between the rod body 63 and the shaft rod 32. One end of the support rod 65 close to the first block body 64 is fixedly connected with a second block body 68. A plurality of second slots 69 are sequentially formed in the rod body 63 along the axial direction. During the process that the rod body 63 rotates to drive the support rod 65 to disengage from the first slot 66, the support rod 65 swings on the first block body 64 to drive the second block body 68 into the second slot 69 at the corresponding position.

[0047] Specifically, after the support rod 65 reaches the second position from the first position, the length reserved when the rod body 63 extends out of one end of the shaft rod 32 becomes correspondingly shorter. Also, the rod body 63 provided on the VR glasses should not be too long. Then, when the shortened rod body 63 drives the support rod 65 to move in the reverse direction to compress the first elastic member 60, it is not convenient for the wearer to operate with their hand. Therefore, in this embodiment, a second elastic member 67 is provided between the rod body 63 and the shaft rod 32. That is, when the support rod 65 needs to reach the second position from the first position, first rotate the rod body 63 to drive the support rod 65 to disengage from the first slot 66 inserted therewith. During this process, the support rod 65 will deflect around the connection shaft with the first block 64. The deflection of the support rod 65 drives the second block 68 connected thereto to gradually enter the second slot 69 at the corresponding radial position on the rod body 63. The second block 68 is oval. When the part follows the deflection of the support rod, it does not enter the second slot 69. That is, the positions of the multiple first slots 66 and the multiple second slots 69 correspond one by one. Then, when driving the rod body 63 to move axially, the rod body 63 can drive the first block 64 to move together. The first block 64 drives each support rod 65 to move to the second position. During this process, the elastic force of the second elastic member 67 increases, and the elastic force of the first elastic member 60 becomes smaller. To facilitate the operation of the shortened rod body 63, after the support rod 65 reaches the second position, rotate the rod body 63 in the reverse direction. The support rod 65 is inserted into the first slot 66 at the second position, and the second block 68 disengages from the second slot 69 inserted therewith. Then, under the action of the restoring elastic force of the second elastic member 67, the rod body 63 can move in the reverse direction to reset. Another second slot 69 on the reset rod body 63 will still be aligned with the second block 68 at this time in the radial direction (that is, when rotating the rod body 63 at this time, the second block 68 will also be inserted into the corresponding second slot 69). In this way, the rod body 63 can return to the original extended length, so that it is easy for the wearer to operate. Then, when the support rod 65 returns from the second position to the first position, first rotate the rod body 63 to drive the support rod 65 to disengage from the insertion into the first slot 66 at the second position. At the same time, the second block 68 is inserted into the corresponding second slot 69 on the rod body 63. Then, drive the rod body 63 to move in the direction away from the second limiting block 7. The support rod 65 is used to push the ring body 61 to move to compress the first elastic member 60. At this time, the second elastic member 67 is stretched and its elastic force becomes larger. After the support rod 65 returns to the first position, rotate the rod body 63 in the reverse direction. The support rod 65 is inserted into the first slot 66 at the first position, and the second block 68 disengages from the second slot 69. Under the action of the restoring elastic force of the second elastic member 67, the rod body 63 resets. The stiffness coefficient of the first elastic member 60 is greater than that of the second elastic member 67. The second elastic member only provides power for the reset of the rod body 63.

[0048] When the support rod 65 is inserted into any one of the first slots 66 and when the second block 68 is inserted into any one of the second slots 69, it is difficult to achieve precise alignment in the radial direction. Therefore, in this embodiment, the adjacent positions of the two first slots 66 are provided with rounded corner structures at the adjacent positions, and the adjacent positions of the two second slots 69 are provided with rounded corner structures at the adjacent positions. By utilizing the characteristics of the rounded corner structures, even when the support rod 65 abuts against the position between two adjacent first slots 66, it can slide along the arc of the rounded corner to enter the first slot 66. The same applies to the insertion of the second block 68 into any one of the second slots 69, and thus no further elaboration will be made here.

[0049] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
