Description

Technical Field

[0001] This utility model relates to the technical field of AR glasses production and testing equipment, and in particular to a fixing structure. Background Technology

[0002] During the manufacturing process, AR glasses need to be fixed on an optical performance testing machine for testing.

[0003] However, due to the significant differences in the size and shape of AR glasses currently on the market, ordinary optical performance testing machines cannot properly fix AR glasses of different sizes. Often, it is necessary to customize the fixture according to the size of the AR glasses, resulting in higher production costs and lower production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a fixing structure that can adapt to and fix AR glasses of different sizes, addressing the problem that the current fixing structure cannot meet the fixing requirements of AR glasses of different shapes and sizes.

[0005] This application provides a fixing structure for fixing AR glasses. The AR glasses include a frame and two temples hinged to both ends of the frame. The structure includes a frame fixing module and two temple fixing modules lockably hinged to both ends of the frame fixing module. The frame fixing module is used to support and fix the frame, and the two temple fixing modules are used to fix the two temples respectively.

[0006] The temple fixing module has a locked state and an unlocked state. In the locked state, the temple fixing module is fixed to the frame fixing module. In the unlocked state, the temple fixing module can rotate relative to the frame fixing module about the hinge center axis.

[0007] In one embodiment, the frame fixing module includes a second adjustment plate, and the temple fixing module includes a temple bracket and a screw.

[0008] One of the second adjusting plate and the temple bracket is provided with a hinge groove, and the other is provided with a hinge part embedded in the hinge groove. The screw passes through the inner wall of one side of the hinge groove and the hinge part in a third direction to be threadedly connected to the inner wall of the other side of the hinge groove. The bottom wall of the hinge groove is provided with a deformation groove so as to adjust the unlocking state and locking state of the temple fixing module by rotating the screw.

[0009] In one embodiment, the temple fixing module includes a temple bracket and an elastic element. The temple bracket is lockably hinged to the frame fixing module. At least one first pin protrudes from the temple bracket. One end of the elastic element is fixed to the temple bracket, and the other end has an opening. The elastic element wraps around the temple and the temple bracket, and the other end is sleeved on one of the first pins.

[0010] In one embodiment, the frame fixing module includes a base for supporting the frame, a frame fixing component disposed on the base, and an adjusting component adjustablely fixed to both ends of the base;

[0011] The frame fixing assembly is used to limit the displacement of the frame along a first direction and a third direction;

[0012] The temple fixing module is lockably hinged to the adjustment assembly, which is used to adjust the position of the hinge center axis relative to the base along a second direction and a third direction.

[0013] In one embodiment, the adjustment assembly includes a first adjustment plate and a second adjustment plate. The first adjustment plate is L-shaped, and one side of the L-shape is adjustablely fixed to the base along a second direction. The second adjustment plate is adjustablely fixed to the other side of the first adjustment plate along a third direction.

[0014] In one embodiment, the adjusting assembly further includes a first bolt and a second bolt;

[0015] The first adjusting plate has a through hole extending in the second direction, and the first bolt passes through the first hole to be threadedly connected to the base to clamp the first adjusting plate.

[0016] The second adjusting plate has a through hole extending in a third direction, and the second bolt passes through the second hole to be threadedly connected to the first adjusting plate to clamp the second adjusting plate.

[0017] In one embodiment, the first adjusting plate has two parallel first strip holes, and a first pin is fixed on the base. The first pin is inserted into one of the first strip holes, and the first bolt passes through the other first strip hole.

[0018] The second adjusting plate has two parallel second strip-shaped holes. A second pin is fixed on the first adjusting plate. The second pin is inserted into one of the second strip-shaped holes, and the second bolt passes through the other second strip-shaped hole.

[0019] In one embodiment, the adjustment assembly further includes a support member that is adjustablely fixed to the second adjustment plate along a first direction and is used to support the mirror frame, and there is a gap between the support member and the base along a third direction.

[0020] In one embodiment, the adjustment assembly further includes a third bolt, and a third strip-shaped hole extending along a first direction is provided through the second adjustment plate. The third bolt passes through the third strip-shaped hole and is threadedly connected to the support member, so that the support member is adjustablely fixed to the second adjustment plate along the first direction.

[0021] In one embodiment, the frame fixing assembly includes a second pin, a guide shaft, a third pin, and a spring. The second pin is fixed to the base. The base has a guide hole in a third direction and a fourth strip-shaped hole that communicates with the guide hole and extends in the third direction. The guide shaft is inserted into the guide hole. The third pin is fixed to the guide shaft and extends through the fourth strip-shaped hole to the outside of the base. The two ends of the spring are fixed to the guide shaft and the inner wall of the guide hole, respectively. After the spring deforms, it can drive the third pin to move closer to the second pin and clamp the frame.

[0022] In one embodiment, the frame fixing assembly further includes a post, a pressure rod, and a fourth bolt. The post is fixed to the base, the pressure rod is sleeved on the post along a first direction, the fourth bolt is threaded to the pressure rod and passes through the pressure rod to abut against the post, and the projection of the pressure rod along a third direction is located between the two nose pads of the frame.

[0034] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0035] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0038] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0040] For ease of description, in this application, the direction parallel to the hinge center axis of the temple fixing module 200 is defined as the first direction, the direction along the length of the frame 1 and perpendicular to the first direction is defined as the second direction, and the direction perpendicular to both the first and second directions is defined as the third direction.

[0041] Please combine Figure 1 as well as Figure 2 As shown, this application provides a fixing structure for fixing AR glasses. The AR glasses include a frame 1 and two temples 2 hinged to both ends of the frame 1. The frame fixing module 100 and two temple fixing modules 200 lockably hinged to both ends of the frame fixing module 100 are included. The frame fixing module 100 is used to support and fix the frame 1, and the two temple fixing modules 200 are used to fix the two temples 2 respectively. The temple fixing modules 200 have a locked state and an unlocked state. In the locked state, the temple fixing modules 200 are fixed to the frame fixing module 100. In the unlocked state, the temple fixing modules 200 can rotate relative to the frame fixing module 100 about the hinge center axis.

[0042] In this application, the frame 1 and two temples 2 of the AR glasses are fixed by the frame fixing module 100 and the two temple fixing modules 200 respectively. The two temple fixing modules 200 can be rotated and adjusted according to the different appearance sizes of the AR glasses, and locked after being adjusted to a suitable position to fix the temples 2. Together with the fixing of the position of the frame fixing module 100, three-point fixation can be achieved, thereby realizing a reliable fixation of AR glasses of different shapes and sizes, effectively improving the versatility of the fixing structure of this application.

[0043] Specifically, the distance between the two temple fixing modules 200 is greater than the distance between the two temples 2 of conventional AR glasses. In other words, the two temples 2 of AR glasses are located between the two temple fixing modules 200.

[0044] It is understandable that since the AR glasses are located between the two temple fixing modules 200, after the frame fixing module 100 supports and fixes the frame 1, for AR glasses of different shapes and sizes, rotating the temple fixing module 200 will always make the temple fixing module 200 abut against the temple 2. At this time, the temple fixing module 200 is locked to fix it to the temple 2.

[0045] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the frame fixing module 100 includes a second adjusting plate 32, and the temple fixing module 200 includes a temple bracket 210 and a screw 220; one of the second adjusting plate 32 and the temple bracket 210 is provided with a hinge groove 300, and the other is provided with a hinge part 400 embedded in the hinge groove 300. The screw 220 passes through one side inner wall of the hinge groove 300 and the hinge part 400 in a first direction to be threadedly connected to the other side inner wall of the hinge groove 300. The bottom wall of the hinge groove 300 is provided with a deformation groove 310 so as to adjust the unlocking state and locking state of the temple fixing module 200 by rotating the screw 220; the central axis of the screw 220 is the hinge central axis of the temple fixing module 200.

[0046] Specifically, the presence of the deformation groove 310 allows for a certain deformation space in the component it is located in. Combined with the rotation of the screw 220, this drives the inner walls on both sides of the hinge groove 300 to move closer or further apart. It should be understood that when the inner walls on both sides of the hinge groove 300 clamp the hinge part 400, the two are relatively fixed, and the temple fixing module 200 is in a locked state. Conversely, when the inner walls on both sides of the hinge groove 300 separate from the hinge part 400, the hinge part 400 can rotate relative to the screw 220, and the temple fixing module 200 is in an unlocked state.

[0047] Furthermore, in some embodiments, the hinge groove 300 is formed in the second adjusting plate 32, the hinge portion 400 is disposed in the temple bracket 210, the hinge groove 300 passes through the second adjusting plate 32 in the second direction and opens towards the temple bracket 210 in the third direction, the bottom end of the screw 220 abuts against the bottom wall of the second adjusting plate 32, and the top end is threadedly connected to the top of the second adjusting plate 32.

[0048] Furthermore, in some embodiments, one end of the screw 220 is fixed with a knob, and the other end is threadedly connected to the inner wall of the hinge groove 300. The knob can abut against the outer wall of the component where the hinge groove 300 is located, and cooperate with the threaded connection of the other end of the screw 220 to clamp the hinge part 400; or both ends of the screw 220 are respectively threadedly connected to the inner walls of both sides of the hinge groove 300, and the threads on both sides are in opposite directions, so that when the screw 220 rotates, the inner walls of both sides of the hinge groove 300 move closer or further away from each other.

[0049] Of course, in some other embodiments, other connection structures may be used between the temple fixing module 200 and the frame fixing module 100, as long as the temple fixing module 200 can rotate relative to the frame fixing module 100 and can be locked or unlocked as needed. This application will not give examples of each of these.

[0050] Furthermore, in some embodiments, the deformation groove 310 is located near the side where the screw 220 is threadedly connected to the hinge groove 300; as the screw 220 rotates, a tensile force is generated at the threaded connection position, and the deformation groove 310 will deform under the action of the tensile force to clamp the hinge part 400. By setting the deformation groove 310 near the threaded connection position, the deformation of the screw 220 at the same rotation angle is more obvious, which makes it easier for the operator to adjust the angle of the temple fixing module 200.

[0051] Please refer to Figure 4 As shown, in some embodiments, the temple fixing module 200 includes a temple support 210 and an elastic member 230. The temple support 210 is lockably hinged to the frame fixing module 100. At least one first pin 211 protrudes from the temple support 210. One end of the elastic member 230 is fixed to the temple support 210, and the other end has an opening. The elastic member 230 wraps around the temple 2 and the temple support 210, and the other end is sleeved on one of the first pins 211 (not shown).

[0052] The elastic element 230 is a rubber band or other elastic strip-shaped part. By tightening the elastic element 230, wrapping the temple 2 and the temple bracket 210, and then fitting the other end of the elastic element 230 onto the first pin 211, the temple 2 can be clamped and fixed to the temple bracket 210. After the test is completed, the fixation can be released simply by removing the opening of the elastic element 230 from the first pin 211. Since one end of the elastic element 230 is fixed to the temple bracket 210, the elastic element 230 will not fall off. When fixing the next pair of AR glasses, it is only necessary to tighten the elastic element 230 and wrap it again, which effectively reduces the difficulty of operation.

[0053] Specifically, in some embodiments, the temple fixing module 200 further includes a clamping plate 212, which is fixed to the temple bracket 210 by bolts to clamp and fix the elastic member 230; more specifically, the clamping plate 212 and the temple 2 are located on both sides of the temple bracket 210 to avoid interference between the clamping plate 212 and the temple 2.

[0054] Preferably, the temple 2 is located inside the temple bracket 210, and the clamping plate 212 is fixed to the outside of the temple bracket 210 to facilitate the loading and unloading of the clamping plate 212.

[0055] In some embodiments, the temple support 210 is provided with first pins 211 on both sides along the third direction, and multiple first pins 211 are provided at intervals along the length direction of the temple support 210 on each side; depending on the size of the temple 2, the position of the winding end of the elastic element 230 is different. By providing multiple first pins 211, the winding and fixing requirements of different sizes of temple 2 can be adapted to ensure reliable fixing and further improve versatility.

[0056] Please combine Figure 2 as well as Figure 5 As shown, in some embodiments, the frame fixing module 100 includes a base 10 for supporting the frame 1, a frame fixing component 20 disposed on the base 10, and an adjusting component 30 adjustablely fixed to both ends of the base 10; the frame fixing component 20 is used to limit the displacement of the frame 1 along a first direction and a third direction; the temple fixing module 200 is lockably hinged to the adjusting component 30, and the adjusting component 30 is used to adjust the position of the hinge center axis relative to the base 10 along a second direction and a third direction.

[0057] The position of the two temple fixing modules 200 along the second direction and the third direction can be adjusted by adjusting the component 30. The adjustment along the second direction can accommodate AR glasses with different frame widths 1, while the adjustment along the third direction can accommodate AR glasses with different hinge positions of the temple 2. This ensures that the hinge axis of the temple 2 corresponds to the hinge axis of the temple fixing module 200, and avoids damage to the AR glasses when adjusting the opening angle of the temple 2 through the temple fixing module 200.

[0058] In some embodiments, a buffer block is fixed on the top surface of the base 10. The buffer block is made of polyurethane, resin or other materials with low hardness. The buffer block is used to support the frame 1. On the one hand, it can protect the AR glasses and prevent the frame 1 from being bumped or damaged. On the other hand, it can play a certain role in shock absorption and reduce external interference.

[0059] More specifically, in some embodiments, the AR glasses are placed upside down on the base 10, that is, the top surface of the frame 1 is in contact with the buffer block, and the top surface of the frame 1 is relatively flush, which makes it more stable when fixed with the frame fixing component 20.

[0060] Please combine Figure 2 as well as Figure 6 As shown, in some embodiments, the adjustment assembly 30 includes a first adjustment plate 31 and a second adjustment plate 32. The first adjustment plate 31 is L-shaped, and one side of the L-shape is adjustablely fixed to the base 10 along a second direction. The second adjustment plate 32 is adjustablely fixed to the other side of the first adjustment plate 31 along a third direction.

[0061] In some embodiments, the L-shaped first adjustment plate 31 corresponds to the angled position of the base 10 to reduce space occupation.

[0062] Please combine Figure 2 as well as Figure 6 As shown, in some embodiments, the adjusting assembly 30 further includes a first bolt 33 and a second bolt 34; the first adjusting plate 31 has a through-hole 311 extending in a second direction, and the first bolt 33 passes through the first bolt 311 to be threadedly connected to the base 10 to clamp the first adjusting plate 31; the second adjusting plate 32 has a through-hole 321 extending in a third direction, and the second bolt 34 passes through the second bolt 321 to be threadedly connected to the first adjusting plate 31 to clamp the second adjusting plate 32.

[0063] Specifically, the base 10 has a threaded hole on its side along the third direction, the first adjusting plate 31 passes through the first strip hole 311 along the third direction, and the first bolt 33 passes through the first strip hole 311 to be threadedly connected to the base 10; the first adjusting plate 31 has a threaded hole along the second direction, the second adjusting plate 32 passes through the second strip hole 321 along the second direction, and the second bolt 34 passes through the second strip hole 321 to be threadedly connected to the second adjusting plate 32. At this time, the second adjusting plate 32 is clamped and fixed between the second bolt 34 and the first adjusting plate 31.

[0064] Of course, in some other embodiments, the first adjusting plate 31 can also be clamped and fixed between the second bolt 34 and the first adjusting plate 31. It is only necessary to open a strip hole through the first adjusting plate 31 and open a threaded hole on the second adjusting plate 32.

[0065] In addition, in some other embodiments, the adjustment component 30 can also adopt other commonly used connection methods, which only require adjusting the temple fixing module 200 to the base 10 in an adjustable manner along the second direction and the third direction.

[0066] Please combine Figure 2 as well as Figure 6 As shown, in some embodiments, the first adjusting plate 31 has two parallel first strip holes 311 through it, and a first pin is fixed on the base 10. The first pin is inserted into one of the first strip holes 311, and a first bolt 33 passes through the other first strip hole 311. The second adjusting plate 32 has two parallel second strip holes 321 through it, and a second pin is fixed on the first adjusting plate 31. The second pin is inserted into one of the second strip holes 321, and a second bolt 34 passes through the other second strip hole 321.

[0067] It is understandable that the pin can guide the slotted hole, ensuring that after the first bolt 33 is loosened, the first adjusting plate 31 can move only in the second direction, and after the second bolt 34 is loosened, the second adjusting plate 32 can move only in the third direction.

[0068] Of course, in some other embodiments, a greater number of strip holes and corresponding pins may be provided to further enhance the guiding and limiting capabilities. This application will not list them all here.

[0069] In some embodiments, two first strip holes 311 are arranged symmetrically in the upper and lower parts, and two second strip holes 321 are arranged symmetrically in the upper and lower parts to reduce space occupation and reduce the overall volume of the fixing structure of this application.

[0070] In some embodiments, at least two pins are inserted into the first strip hole 311 and the second strip hole 321 respectively, so as to ensure that after the first bolt 33 or the second bolt 34 is unscrewed, the first adjusting plate 31 and the second adjusting plate 32 can still be supported and limited by the corresponding pins, and will not loosen due to insufficient limiting.

[0071] Please combine Figure 6 as well as Figure 7 As shown, in some embodiments, the adjustment assembly 30 further includes a support member 35, which is adjustablely fixed to the second adjustment plate 32 along a first direction and is used to support the mirror frame 1. There is a gap between the support member 35 and the base 10 along a third direction.

[0072] As can be understood, in the fixing structure of this application, the base 10 and the support 35, which are spaced apart along the third direction, respectively support the frame 1. Therefore, by adjusting the position of the support 35 along the first direction, the tilt angle of the frame 1 can be changed. On the one hand, this can meet the detection requirements of different scenarios, and on the other hand, it can ensure that the hinge axis of the temple 2 is parallel to the hinge axis of the temple fixing module 200, so as to avoid damage to the AR glasses when adjusting the opening angle of the temple 2 through the temple fixing module 200.

[0073] Preferably, in some embodiments, the support member 35 is located on the side closer to the screw 220 along a third direction, so as to maximize the distance between the support member 35 and the base 10 along the third direction, thereby increasing the adjustment sensitivity and adjustment range.

[0074] In some embodiments, the support member 35 is made of polyurethane, resin or other materials with low hardness, so as to prevent the frame 1 from being bumped or damaged and to provide shock resistance and reduce external interference.

[0075] Please combine Figure 6 as well as Figure 7 As shown, in some embodiments, the adjusting assembly 30 further includes a third bolt 36, and a third strip hole 322 extending in the first direction is provided through the second adjusting plate 32. The third bolt 36 passes through the third strip hole 322 and is threadedly connected to the support member 35 to clamp the second adjusting plate 32.

[0076] In some embodiments, the support member 35 is located inside the second adjusting plate 32, and the third bolt 36 passes through the third strip hole 322 from the outside of the second adjusting plate 32 to be threadedly connected to the support member 35, so that the support member 35 is adjustablely fixed to the second adjusting plate 32 along the first direction.

[0077] Of course, in some other embodiments, the support member 35 can also be set on the second adjustment plate 32 by other connection methods, as long as the fixed position of the support member 35 along the first direction can be adjusted as needed. This application will not give examples of each one here.

[0078] Please combine Figure 2 as well as Figure 8 As shown, in some embodiments, the frame fixing assembly 20 includes a second pin 21, a guide shaft 22, a third pin 23, and a spring 24. The second pin 21 is fixed to the base 10. The base 10 has a guide hole 11 in a third direction. The base 10 also has a fourth strip hole 12 that communicates with the guide hole 11 and extends in a third direction. The guide shaft 22 is inserted into the guide hole 11. The third pin 23 is fixed to the guide shaft 22 and extends through the fourth strip hole 12 to the outside of the base 10. The two ends of the spring 24 are fixed to the guide shaft 22 and the inner wall of the guide hole 11, respectively. After the spring 24 is deformed, it can drive the third pin 23 to move closer to the second pin 21 and clamp the frame 1.

[0079] Specifically, when the operator pulls the guide shaft 22 away from the second pin 21 in a third direction, the spring 24 deforms under force, and the third pin 23 moves away from the second pin 21 under the action of the guide shaft 22. At this time, the AR glasses can be placed between the second pin 21 and the third pin 23. After placement, the guide shaft 22 is released, and the guide shaft 22 and the third pin 23 return to their original position towards the second pin 21 under the elastic force of the spring 24, thereby cooperating with the second pin 21 to clamp the frame 1.

[0080] In some embodiments, the spring 24 is a compression spring, with one end of the spring 24 fixed to the guide shaft 22 and the other end fixed to the inner wall of the guide hole 11 along a third direction away from the second pin 21; or the spring 24 is a tension spring, with one end of the spring 24 fixed to the guide shaft 22 and the other end fixed to the inner wall of the guide hole 11 along a third direction close to the second pin 21.

[0081] Furthermore, in some embodiments, at least two second pins 21 are fixedly spaced along the second direction on the base 10; even further, in some embodiments, the second pins 21 on the base 10 are symmetrically arranged along the second direction, thereby providing uniform support for both sides of the frame 1.

[0082] Please combine Figure 2 as well as Figure 8As shown, in some embodiments, the frame fixing assembly 20 further includes a column 25, a pressure rod 26, and a fourth bolt 27. The column 25 is fixed to the base 10, the pressure rod 26 is sleeved on the column 25 along the first direction, and the fourth bolt 27 is threaded to the pressure rod 26 and passes through the pressure rod 26 to abut against the column 25. The projection of the pressure rod 26 along the third direction is located between the two nose pads of the frame 1.

[0083] It is understandable that by adjusting the pressure rod 26 to abut against the frame 1 in the first direction, the pressure rod 26, together with the base 10, can clamp and fix the frame 1 in the first direction. On this basis, the projection of the pressure rod 26 in the third direction is located between the two nose pads of the frame 1, so as to further limit the displacement of the frame 1 in the second direction through the locking and limiting between the pressure rod 26 and the two nose pads.

[0084] In some embodiments, the second pin 21, the third pin 23, and the pressure rod 26, which are in direct contact with the AR glasses, are made of polyurethane, resin, or other materials with low hardness, in order to prevent the frame 1 from being bumped or damaged and to provide shock resistance and reduce external interference.

[0085] Of course, in some other embodiments, the frame fixing component 20 may also use other commonly used limiting structures to limit and fix the frame 1, as long as it can limit the displacement of the frame 1 along the first direction and the third direction. This application will not give examples of each one here.

[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0087] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
