The invention provides a head-mounted device, which can be AR glasses (AR: Augmented Reality), VR glasses (VR: Virtual Reality), MR glasses (MR: Mix Reality) and the like.

In an embodiment of the present invention, referring to fig. 1 to fig. 3, the head-mounted device includes a housing 10, a display assembly 70, a mounting base 20, and a sliding member 30, the housing 10 has a mounting cavity and a sliding hole 11 penetrating through a wall of the mounting cavity, and the display assembly 70 is disposed in the mounting cavity. The mount 20 is provided with a lens 24, and the mount 20 is slidably mounted in the mounting cavity in the front-rear direction. The slider 30 is connected to the mount 20, and the slider 30 is slidably mounted to the slide hole 11.

A linkage structure is arranged between the mounting seat 20 and the sliding part 30, the extending direction of the linkage structure is inclined relative to the sliding direction of the sliding hole 11, and when the sliding part 30 moves along the sliding direction of the sliding hole 11, the mounting seat 20 is driven to move along the front-back direction through the linkage structure so as to adjust the distance between the lens 24 and the display assembly 70.

It should be understood that when the user wears the head mounted device, the display assembly 70 and the lens 24 are positioned on the front side of the user, and the display assembly 70 is positioned on the front side of the lens 24, so the front-back direction of the head mounted device is along the front-back direction of the user with reference to the front-back direction of the user, i.e., the state that the head mounted device is worn on the head of the user.

In this embodiment, the housing 10 has a mounting opening facing rearward, the mounting opening communicates with the mounting cavity, and the mounting base 20 is mounted in the mounting cavity through the mounting opening so as to be slidable forward and backward. The mounting seat 20 is further provided with an eye cover 23, the lens 24 is exposed in the eye cover 23, the eye cover 23 is provided with a wearing opening, the wearing opening is opposite to the lens 24, and when the user wears the head-mounted device, the eye cover 23 is worn on the eyes of the user through the wearing opening. The slide hole 11 is elongated, and the slider 30 is movable along the longitudinal direction of the slide hole 11, that is, the sliding direction of the slider 30 (i.e., the sliding direction of the slide hole 11) is the longitudinal direction of the slide hole 11.

The sliding member 30 is connected to the mounting seat 20 through an interlocking structure, and the sliding member 30 can slide relative to the housing 10 along the length direction of the sliding hole 11, and the extending direction of the interlocking structure is inclined relative to the sliding direction of the sliding hole 11, and at least one of the extending direction of the interlocking structure and the sliding direction of the sliding hole 11 is inclined relative to the front-back direction. Since the mount 20 can move only in the front-rear direction with respect to the housing 10, when the slider 30 moves in the slide hole 11, the interlocking structure can convert the force applied by the slider 30 into a force that drives the mount 20 in the front-rear direction, so that the mount 20 can move in the front-rear direction. The distance between the lens 24 and the display assembly 70 can be adjusted, so that users with different degrees of myopia can obtain clear images when using the head-mounted equipment, and the use requirements of more users can be met. The length direction of the sliding hole 11 may be perpendicular to the front-back direction, or the length direction of the sliding hole 11 may be inclined with respect to the front-back direction.

In the technical scheme of the invention, the linkage structure is arranged between the mounting seat 20 and the sliding part 30, so that the extending direction of the linkage structure is inclined relative to the sliding direction of the sliding hole 11, and when the sliding part 30 moves along the sliding direction of the sliding hole 11, the mounting seat 20 can be driven to move along the front-back direction through the linkage structure. Thereby adjusting the distance between the lens 24 and the display assembly 70, so that users with different myopia degrees can obtain clear images when using the head-mounted equipment, and the use requirements of more users are met. And compare in the mode that sliding hole 11 extends along the fore-and-aft direction, and slider 30 and mount pad 20 fixed connection, slide at slider 30 like this and drive the mode that mount pad 20 moved through linkage structure, can realize mount pad 20 and finely tune, promote the regulation precision.

For example, referring to fig. 3 to 5, in an embodiment, the linkage structure includes a sliding groove 41 and a sliding protrusion 42, the sliding groove 41 is disposed on the mounting base 20 and disposed toward the sliding hole 11, an extending direction of the sliding groove 41 is inclined relative to a sliding direction of the sliding hole 11, and the sliding protrusion 42 is disposed on the sliding member 30 and slidably mounted on the sliding groove 41. Specifically, the slide protrusion 42 is integrally formed with the slider 30, and when the slider 30 moves in the sliding direction of the slide hole 11, the slide protrusion 42 can also move within the slide groove 41 relative to the mount 20. In this process, when the sliding member 30 slides from one end of the sliding hole 11 to the other end and the sliding protrusion 42 presses the front side wall of the sliding slot 41, the mounting base 20 can be driven to move forward, so that the distance between the lens 24 and the display assembly 70 can be increased. When the sliding member 30 slides in the opposite direction, the sliding protrusion 42 presses the rear side wall of the sliding slot 41, and the mounting base 20 can be driven to move backward, so that the distance between the lens 24 and the display assembly 70 can be reduced. The linkage structure is simple in structure, the structures of the mounting seat 20 and the shell 10 can be simplified, and production cost is reduced. Of course, in other embodiments, the linkage structure may also include a slide rail disposed on the mounting base 20 and a slide block disposed on the sliding member 30, and the slide block is slidably mounted on the slide rail. Or, the linkage structure includes a guide pillar disposed on the mounting base 20 and a guide sleeve disposed on the sliding member 30, and the guide sleeve is slidably sleeved on the guide pillar.

In one embodiment, the sliding direction of the sliding hole 11 is perpendicular to the front-back direction, and the extending direction of the sliding slot 41 is inclined relative to the front-back direction. That is, the sliding direction of the slider 30 is perpendicular to the front-rear direction, when the user needs to adjust the distance between the lens 24 and the display assembly 70, the user can move the slider 30 in the direction perpendicular to the front-rear direction (left-right direction or up-down direction), which can facilitate the user's application of force. Of course, in other embodiments, the extending direction of the sliding groove 41 may be perpendicular to the front-back direction, and the sliding direction of the sliding hole 11 may be inclined with respect to the front-back direction.

Referring to fig. 4 and 6, in an embodiment, the sliding protrusion 42 has a sliding surface 421, the sliding surface 421 faces the bottom of the sliding groove 41, and the sliding surface 421 is a convex arc surface. Specifically, when the sliding protrusion 42 slides in the sliding groove 41, the sliding surface 421 contacts the bottom of the sliding groove 41, and by providing the sliding surface 421 with a convex arc surface so that the sliding surface 421 and the bottom of the sliding groove 41 are in line contact, the contact area between the sliding surface 421 and the bottom of the sliding groove 41 can be reduced, and the frictional force between the sliding protrusion 42 and the mount 20 can be reduced. Of course, in other embodiments, the sliding surface 421 can be a plane.

Referring to fig. 4 to 6, in an embodiment, the sliding slot 41 has a first side wall 411 and a second side wall 412 opposite to each other, an elastic structure is disposed between the sliding protrusion 42 and the first side wall 411, the elastic structure has elastic deformation along the distribution direction of the first side wall 411 and the second side wall 412, and when the sliding protrusion 42 is installed on the sliding slot 41, the elastic structure pushes the sliding protrusion 42 against the second side wall 412. That is, the elastic structure always has a tendency to drive the sliding protrusion 42 to move toward the second side wall 412, which is equivalent to the sliding protrusion 42 being slidably mounted to the chute 41 with an interference fit. Thus, a movable gap between the sliding protrusion 42 and the second sidewall 412 (the first sidewall 411) can be avoided, and the sliding protrusion 42 can be effectively prevented from loosening. The sliding convex part 42 is effectively limited to move along the distribution direction of the first side wall 411 and the second side wall 412 in a deviating manner, the sliding convex part 42 is ensured to stably slide along the length direction of the sliding chute 41, and the precision of adjusting the movement of the mounting base 20 along the front-back direction can be improved. Further, the elastic structure has elasticity, and in the case where stable sliding of the sliding protrusion 42 is ensured, the abutting force of the sliding protrusion 42 with the second side wall 412 is made small, so that the frictional force between the sliding protrusion 42 and the second side wall 412 is made small, and the abrasion between the sliding protrusion 42 and the second side wall 412 can be reduced. Of course, in other embodiments, the elastic structure may also urge the sliding protrusion 42 against the first sidewall 411. In addition, the elastic structure may not be provided.

In one embodiment, the elastic structure includes an elastic arm 51, the elastic arm 51 is connected to the mounting base 20 and has elastic deformation along the distribution direction of the first side wall 411 and the second side wall 412, the elastic arm 51 at least partially extends into the sliding slot 41, and the elastic arm 51 abuts against the side of the sliding protrusion 42 away from the second side wall 412. The distance between the elastic arm 51 and the second side wall 412 is smaller than the size of the sliding protrusion 42, when the sliding protrusion 42 is inserted into the sliding slot 41, the sliding protrusion 42 presses the elastic arm 51 to deform the elastic arm 51 toward the outside of the sliding slot 41, and when the sliding protrusion 42 is installed in place, the elastic arm 51 has a tendency to elastically return toward the inside of the sliding slot 41, so that the sliding protrusion 42 can be abutted against the second side wall 412. By providing the elastic arm 51 in the mount base 20 in such a manner that the sliding protrusion 42 is slidably fitted between the second side wall 412 and the elastic arm 51 with interference fit, the structure of the sliding protrusion 42 can be simplified, and the elastic arm 51 can be provided in the mount base 20 with a sufficient space, thereby making it possible to sufficiently utilize the space in the mount base 20. Wherein the elastic arm 51 may be provided at the first sidewall 411. Alternatively, the first sidewall 411 may be provided with a relief notch, the elastic arm 51 is disposed in the relief notch, and the elastic arm 51 extends out of the relief notch towards the second sidewall 412, that is, the elastic arm 51 partially protrudes out of the second sidewall 412. Therefore, the length of the elastic arm 51 can be ensured to be longer, the elastic arm 51 has better elasticity, the distance between the second side wall 412 and the sliding protrusion 42 can be made to be smaller, and the offset of the sliding protrusion 42 along the distribution direction of the first side wall 411 and the second side wall 412 can be reduced. Of course, in other embodiments, the elastic arm 51 may be provided on the sliding protrusion 42, and the elastic arm 51 may abut against the first side wall 411. In addition, the elastic structure may also include a spring plate or a spring, that is, the spring plate (spring) elastically abuts between the first sidewall 411 (the second sidewall 412) and the sliding protrusion 42.

In one embodiment, the resilient arms 51 are integrally injection molded with the mounting base 20. Elastic arm 51 and dress seat are the working of plastics promptly, so can be convenient for the shaping, still reduced the assembly process of elastic arm 51 with mount pad 20, can simplify the assembly, promote production efficiency. Of course, in other embodiments, the resilient arm 51 may be bonded, welded or soldered to the mounting base 20. The elastic arm 51 may be a metal member, and the elastic arm 51 may be fitted to the mount 20 by an injection molding process.

In an embodiment, the elastic arm 51 extends along the length direction of the sliding slot 41, two ends of the elastic arm 51 are connected to the mounting base 20, the elastic arm 51 is provided with an abutting portion 511, the abutting portion 511 is located between the two ends of the elastic arm 51, the abutting portion 511 extends into the sliding slot 41 and abuts against the surface of the sliding protrusion 42 departing from the second side wall 412, the slot bottom of the sliding slot 41 is provided with a yielding hole 221, and the yielding hole 221 is arranged corresponding to the elastic arm 51. That is, the relief hole 221 is disposed between the second sidewall 412 and the elastic arm 51, which is equivalent to disposing the relief hole 221 on the groove bottom of the sliding groove 41, so that the elastic arm 51 is formed on the first sidewall 411, and thus the elastic arm 51 and the abutting portion 511 on the elastic arm 51 can be prevented from interfering with the groove bottom of the sliding groove 41, so that the elastic arm 51 has elasticity. In addition, the elastic arm 51 can be integrally formed on the mounting seat 20, as compared with the case where the elastic arm 51 is spaced apart from the bottom of the slide groove 41. In addition, by connecting both ends of the elastic arm 51 to the mounting seats 20, the reliability of the elastic arm 51 can be improved. Of course, in other embodiments, only one end of the elastic arm 51 may be connected to the mounting seat 20, so that the elastic arm 51 has a cantilever structure. In addition, the elastic arm 51 may also extend along the distribution direction of the first side wall 411 and the second side wall 412, in this case, the elastic arm 51 may be provided with a multi-stage bending structure or an arc-shaped bending structure.

In one embodiment, the resilient arms 51 are convexly arched toward the second side wall 412. This enables the abutting portion 511 to extend into the slide groove 41, and increases the length of the elastic arm 51, which is advantageous for increasing the elasticity and structural stability of the elastic arm 51. Of course, in other embodiments, the elastic arm 51 may be provided as a straight arm, and the contact portion 511 may extend into the slide groove 41 and contact the slide protrusion 42.

In one embodiment, the surface of the elastic arm 51 facing the sliding hole 11 is provided with a guiding protrusion 52, a guiding inclined surface 521 is formed on the side of the guiding protrusion 52 facing the second sidewall 412, the guiding inclined surface 521 is connected to the surface of the abutting portion 511 abutting against the sliding protrusion 42, and the guiding inclined surface 521 extends in a direction away from the abutting portion 511 and gradually inclines in a direction away from the second sidewall 412. When the sliding protrusion 42 is inserted into the sliding slot 41, the sliding protrusion 42 can first abut against the guiding slope 521, and the sliding protrusion 42 gradually moves along the guiding slope 521 toward the inside of the sliding slot 41, in the process, the sliding protrusion 42 gradually presses the guiding slope 521, so that the elastic arm 51 gradually deforms until the sliding protrusion 42 is inserted into the sliding slot 41. Therefore, the elastic arm 51 can be automatically deformed and abducted in the process of inserting the sliding convex part 42, the situation that the elastic arm 51 is additionally manually driven to deform so as to abduct the sliding convex part 42 is avoided, and the installation of the sliding convex part 42 is facilitated. Of course, in other embodiments, the edge of the resilient arm 51 away from the bottom of the slot 41 may be beveled. Or the guide slope 521 may not be provided.

Specifically, the connecting plate 22 is located on the side of the mounting portion facing the slide hole 11 and extends forward from the mounting plate 21, the connecting plate 22 is disposed facing the slide hole 11, and the slide groove 41 is disposed on the surface of the connecting plate 22 facing the slide hole 11. By providing the connecting plate 22, the connecting plate 22 can be ensured to be well located in the mounting cavity, so that the sliding hole 11 is correspondingly disposed on the housing 10, the mounting plate 21 can be close to or located at the mounting opening, the distance between the lens 24 and the display assembly 70 is larger, and the adjustable range between the lens 24 and the display assembly 70 can be increased. Of course, in other embodiments, the mounting seat 20 may be provided in a cylindrical shape, and the slide groove 41 may be provided on the outer peripheral surface thereof.

Referring to fig. 5 and 7, in an embodiment, a material reducing groove 222 is disposed on a surface of the connecting plate 22 away from the sliding groove 41, the material reducing groove 222 extends in a direction away from the mounting plate 21 and penetrates through a side surface of the connecting plate 22 away from the mounting plate 21, and the relief hole 221 penetrates through the material reducing groove 222. That is, the material reducing groove 222 is arranged corresponding to the elastic arm 51, which is equivalent to reducing the thickness of the entity of the part of the elastic arm 51 formed on the connecting plate 22, that is, reducing the thickness of the elastic arm 51 along the thickness direction of the connecting plate 22, so that the surface of the elastic arm 51 departing from the sliding hole 11 is the groove bottom surface of the material reducing groove 222, which is favorable for increasing the elasticity of the elastic arm 51. Further, since the relief groove 222 is provided only in a portion corresponding to the elastic arm 51, the influence of the relief groove 222 on the structural strength of the connection plate 22 can be reduced. Of course, in other embodiments, the relief groove 222 may not be provided.

The connecting block 31 has a connecting portion 311, and the connecting portion 311 extends from the sliding hole 11 and is slidable along the longitudinal direction of the sliding hole 11. A fitting gap is formed between the connecting portion 311 and the hole edge of the slide hole 11 in the width direction of the slide hole 11. The sliding block 32 has a receiving groove 321, the connecting portion 311 extends into the receiving groove 321, and the sliding block 32 covers at least a portion of the assembling gap. By covering the sliding block 32 at least partially over the assembly gap. Therefore, the gap at the sliding hole 11 can be reduced, and the possibility that dust and other impurities enter the head-mounted equipment is reduced, so that the possibility that the head-mounted equipment is damaged is reduced.

In one embodiment, the connecting portion 311 has a limiting groove 312, and the edge of the sliding hole 11 extends into the limiting groove 312.

Specifically, the insertion part 322 extends into the insertion groove 313 through the fitting gap, and the toggle part 326 covers the fitting gap. When the connecting portion 311 extends into the receiving groove 321, the insertion portion 322 is mounted in the insertion groove 313, so that the contact area between the connecting block 31 and the sliding block 32 can be increased. When the insertion part 322 penetrates through the assembly gap, the insertion part 322 can limit the connecting part 311 to move along the width direction of the sliding hole 11, so that the hole edge of the sliding hole 11 can be ensured to be always positioned in the limiting groove 312. Of course, in other embodiments, a snap may be provided on the connection block 31 to engage with the snap when the insertion part 322 passes through the sliding hole 11 to limit the movement of the insertion part 322 relative to the connection block 31.

In order to prevent the sliding block 32 from separating from the connecting block 31, in an embodiment, a groove wall of the insertion groove 313 is provided with a limiting protrusion 315, the insertion part 322 is provided with a limiting hole 324, and when the insertion part 322 is inserted into the insertion groove 313, the limiting protrusion 315 is inserted into the limiting hole 324 to limit the insertion part 322 from exiting the insertion groove 313. Specifically, the protruding height of the limiting protrusion 315 is greater than the fit clearance between the insertion part 322 and the insertion groove 313, and in the process of inserting the insertion part 322 into the insertion groove 313, at least one of the limiting protrusion 315, the groove wall of the insertion groove 313, and the insertion part 322 can elastically deform, so as to ensure that the insertion part 322 can be inserted into the position of the limiting hole 324 corresponding to the limiting protrusion 315, so that the limiting protrusion 315 can be clamped into the limiting hole 324. After the limiting protrusion 315 is inserted into the limiting hole 324, the limiting protrusion 315, the wall of the insertion groove 313 or the insertion part 322 elastically returns, and at this time, if the insertion part 322 is to be pulled out from the insertion groove 313, the limiting protrusion 315 abuts against the wall of the limiting hole 324, so as to limit the insertion part 322 from exiting the insertion groove 313. The limiting structure with the limiting protrusions 315 and the limiting holes 324 is arranged, so that the strength of the limiting protrusions 315 and the strength of the limiting holes 324 are high, and the connection reliability of the sliding block 32 and the connecting block 31 can be improved. Of course, in other embodiments, a clamping groove (a clamping protrusion) may be disposed in the insertion groove 313, a buckle may be disposed on the insertion portion 322, and after the insertion portion 322 is inserted into the insertion groove 313, the buckle may be clamped with the clamping groove (the clamping protrusion). In addition, a clamping groove (a clamping protrusion) may be disposed in the accommodating groove 321, a buckle may be disposed on the connecting portion 311, and after the connecting portion 311 is inserted into the accommodating groove 321, the buckle may be clamped with the clamping groove (the clamping protrusion)

To facilitate the insertion of the insertion part 322 into the insertion groove 313, in one embodiment, the limiting protrusion 315 has a first guiding surface 316, the first guiding surface 316 faces the sliding hole 11, and the first guiding surface 316 guides the insertion part 322 when being inserted into the insertion groove 313. Specifically, the first guide surface 316 is connected to a groove wall of the insertion groove 313, and the first guide surface 316 extends obliquely in the protruding direction of the stopper protrusion 315 in the insertion direction of the insertion portion 322 inserted into the insertion groove 313 (the insertion direction of the insertion portion 322 is referred to as the direction indicated by the arrow X in fig. 6, 8, or 9). Therefore, when the insertion part 322 is inserted into the insertion groove 313, the insertion part 322 can slide along the first guide surface 316, and the insertion part 322 can be conveniently inserted into the limiting groove 312.

In one embodiment, the free end of the insertion part 322 has a second guiding surface 323, and the second guiding surface 323 is used for guiding and matching with the limiting protrusion 315. Specifically, the second guide surface 323 is disposed facing the limiting protrusion 315, and the second guide surface 323 gradually extends in a direction away from the limiting protrusion 315 in a direction away from the toggle portion 326, so that when the insertion portion 322 is inserted into the insertion groove 313, the second guide surface 323 can slide relative to the limiting protrusion 315, thereby facilitating the insertion of the insertion portion 322 into the limiting groove 312. In one embodiment, when the limiting protrusion 315 has the first guiding surface 316, the free end of the inserting portion 322 further has a second guiding surface 323.

In an embodiment, the width direction of the limiting protrusion 315 is perpendicular to the insertion direction of the insertion part 322 and the protruding direction of the limiting protrusion 315, and the width of the limiting protrusion 315 is gradually reduced along the insertion direction of the insertion part 322. That is, the cross-sectional shape of the limiting protrusion 315 perpendicular to the protruding direction is substantially triangular, semicircular, or semi-elliptical, etc. Optionally, the width of the limiting hole 324 is also tapered along the insertion direction of the insertion portion 322. Therefore, in the process of inserting the inserting part 322 into the inserting groove 313, the contact area between the inserting part 322 and the limiting protrusion 315 is gradually reduced, so that the friction resistance between the inserting part 322 and the limiting protrusion 315 is reduced, and the inserting part 322 can be conveniently inserted into the inserting groove 313. Of course, in other embodiments, the limiting protrusion 315 may be disposed in a square shape.

In one embodiment, the limiting hole 324 has two adjacent inner wall surfaces 325, the distance between the two inner wall surfaces 325 is gradually reduced along the insertion direction of the insertion portion 322, and when the limiting protrusion 315 is inserted into the limiting hole 324, the two inner wall surfaces 325 abut against the limiting protrusion 315. That is, the inner wall 325 is inclined with respect to the insertion direction of the insertion portion 322, and the width of the limiting hole 324 is gradually reduced along the insertion direction of the insertion portion 322, so that the shape of the limiting hole 324 is matched with the shape of the limiting protrusion 315. After the limiting protrusion 315 is inserted into the limiting hole 324, the two inner wall surfaces 325 abut against the side surfaces of the limiting protrusion 315, so that the insertion part 322 can be limited from exiting the insertion groove 313. By such arrangement, in the direction of the inner wall surface 325 away from the other inner wall surface 325, the thickness between the inner wall surface 325 and the end surface of the insertion part 322 departing from the toggle part 326 is gradually increased, so that the structural strength between the inner wall surface 325 and the end surface of the insertion part 322 departing from the toggle part 326 is high, and the possibility of stress deformation of the limiting hole 324 can be reduced. The hole 324 may be a generally triangular hole, the hole 324 may be a triangular hole, and the two inner walls 325 may be disposed at an obtuse angle, a right angle, or an acute angle. Of course, the limiting hole 324 may be a substantially semicircular hole, a substantially semi-elliptical hole, a substantially square hole, or the like.

The connecting block 31 has a mounting surface 314, the mounting surface 314 is located on a side of the connecting portion 311 facing away from the limiting groove 312, and a limiting protrusion 315 is provided on the mounting surface 314. To facilitate insertion of the insertion portion 322 into the insertion groove 313, in one embodiment, the connection block 31 includes two elastic limiting arms 317, each elastic limiting arm 317 includes a connection section 318 and an extension section 319, the connection section 318 is connected to the mounting surface 314, the extension section 319 is connected to a free end of the connection section 318 and extends toward a lateral direction of the connection section 318, the extension sections 319 of the two elastic limiting arms 317 extend toward each other and are spaced apart, the two extension sections 319 are both spaced apart from the mounting surface 314 to form the insertion groove 313 with the mounting surface 314, and the limiting protrusion 315 is located between the two connection sections 318. I.e. the mounting surface 314 at least partly forms a wall of the insertion groove 313. Thus, when the inserting portion 322 is inserted into the inserting groove 313, the inserting portion 322 can press the extension portion 319 to elastically deform in a direction away from the mounting surface 314, and also drive the connection portion 318 to elastically deform in a direction away from the other elastic limiting arm 317. The elastic limiting arm 317 is arranged in such a way, so that the elastic deformation effect of the elastic limiting arm 317 is better, the abutting acting force between the inserting part 322 and the groove wall of the inserting groove 313 (the surface of the mounting surface 314, the surface of the extension section 319 facing the mounting surface 314 and the surfaces of the two connection sections 318 facing each other) when the inserting part 322 is inserted into the inserting groove 313 can be reduced, the inserting part 322 can be conveniently inserted into the inserting groove 313, the abrasion between the inserting part 322 and the limiting protrusion 315 can be reduced, and the damage condition between the inserting part 322 and the limiting protrusion 315 can be reduced.
