DETAILED DESCRIPTION

[0028] Smart glasses, such as virtual reality (VR) glasses, augmented reality (AR) glasses, mixed reality (MR) glasses, etc., can be applied in various scenarios such as watching, playing, working, and calling, and can provide users with a more immersive experience during use.

[0029] Generally, smart glasses include a frame, a lens, and a nose pad. Specifically, the frame has a mounting opening for mounting the lens, and the lens is mounted in the mounting opening. The nose pad is located on the inner side of the lens, i.e., the side of the lens facing the user's face when the user wears the smart glasses. The nose pad is fixedly connected to the frame and is used to contact the user's nose when the user wears the smart glasses, thereby providing support. However, different users have different nose shapes, which means that the nose pad of the smart glasses may not match the nose shapes of some users, resulting in that the smart glasses cannot be kept in the correct and reliable position when these users wear the smart glasses.

[0030] Therefore, the present application provides a nose pad device and smart glasses to solve the problem that the smart glasses cannot be kept in the correct and reliable position when the user wears the smart glasses. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail below with reference to the drawings.

[0031] The terminology used in the following description merely to convey the particular embodiments and is not intended to limit the application. As used in this specification and the appended claims, the singular forms "a," "an," and "the" include plural referents unless the context clearly dictates otherwise.

[0032] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in additional embodiments," and the like in various places throughout this specification are not necessarily referring to the same embodiment, unless otherwise expressly specified. The terms "including," "containing," "having," and variations thereof are meant to encompass the terms "including but not limited to."

[0033] Figure 1 A front view of a smart glass provided in the present application, Figure 2 A front view of a smart glass provided in the present application, Figure 1 A perspective view of the smart glass shown in FIG. 1. As shown in FIG. 2, Figure 1 A perspective view of the smart glass shown in FIG. 1. As shown in FIG. 2, Figure 2 The smart glass includes a frame 100, a lens 200, and a nose pad device 300. The lens 200 is disposed on the frame 100, and the nose pad device 300 is fixed on the inner side of the lens 200 (i.e., the side facing the user's face when the smart glass is worn by the user). In practice, the nose pad device 300 can be connected to the frame 100, and then fixed on the inner side of the lens 200. Please continue to refer to Figure 2The nose pad device 300 includes a first base 1, a linear transmission assembly 2, a first drive assembly 3, and a nose pad assembly 4. Specifically, the first base 1 includes a first support 11 and a second support 12 that are arranged opposite to and fixedly connected to each other. The first support 11 is used to connect to the frame 100 and is arranged on the inner side of the lens 200, and the second support 12 is used to be arranged on the side of the first support 11 opposite to the lens 200. In a specific implementation, the arrangement direction A of the first support 11 and the second support 12 can be perpendicular to the lens 200. According to actual needs, the arrangement direction A of the first support 11 and the second support 12 can also be at a certain angle to the lens 200. The linear transmission assembly 2 is connected to both the first support 11 and the second support 12, and the linear transmission assembly 2 extends along the arrangement direction A of the first support 11 and the second support 12. The first drive assembly 3 is connected to the linear transmission assembly 2, and the linear transmission assembly 2 is connected to the nose pad assembly 4, so that the first drive assembly 3 can drive the nose pad assembly 4 to move along the arrangement direction A of the first support 11 and the second support 12 through the linear transmission assembly 2, thereby adjusting the position of the nose pad assembly 4 in this direction, so that the smart glasses can adapt to the nose shapes of more users, and thus enable more users to keep the smart glasses in the correct and reliable position when wearing them.

[0034] When the first base 1 is specifically set, the first support 11 and the second support 12 can be connected by a connecting plate 13 or a connecting column. For example, please refer to Figure 3 The schematic structural diagram of the nose support device 300 is shown in FIG. Figure 3 In the nose support device 300 shown, the first support 11 and the second support 12 are connected by two connecting plates 13 arranged side by side, and the linear transmission assembly 2 is arranged between the two connecting plates 13, so that the structural stability of the nose support device 300 is better, thereby making the position of the smart glasses more reliable when the user wears the smart glasses.

[0035] Next, please continue to refer to Figure 3The linear transmission assembly 2 is specifically configured. In some embodiments, the linear transmission assembly 2 includes a first lead screw 21 and a first guide rod 22 which are parallel to each other. The first lead screw 21 includes a first end and a second end. The first end of the first lead screw 21 is rotationally connected to the first support 11. The second end of the first lead screw 21 is rotationally connected to the second support 12. The first driving assembly 3 is connected to the second end of the first lead screw 21. The first driving assembly 3 is used to drive the first lead screw 21 to rotate. The two ends of the first guide rod 22 are respectively connected to the first support 11 and the second support 12. The nose pad assembly 4 is threadedly connected to the first lead screw 21 and is slidingly connected to the first guide rod 22. Therefore, the nose pad assembly 4 can be moved in the arrangement direction A of the first support 11 and the second support 12 under the driving of the first driving assembly 3 and the linear transmission assembly 2. For example, the second end of the first lead screw 21 can be arranged on the second support 12 through a bearing. The first support 11 can be provided with a hole for mounting the first lead screw 21. The first end of the first lead screw 21 is inserted into the hole on the first support 11. The size and surface roughness of the first end of the first lead screw 21 and the hole on the first support 11 can be designed to reduce the possibility of accidental rotation of the first lead screw 21, so that the first lead screw 21 can be rotated as much as possible only under the action of the first driving assembly 3. In addition, in specific implementation, the first guide rod 22 can be two parallel rods. The two first guide rods 22 are distributed on both sides of the first lead screw 21. The nose pad assembly 4 is slidingly connected to the two first guide rods 22 to increase the stability of the nose pad assembly 4 during movement.

[0036] The first driving assembly 3 can have various implementations. For example, as shown in Figure 3 The first driving assembly 3 includes a first knob 31 which is fixedly connected to the second end of the first lead screw 21. In this scheme, the assembly of the nose pad device 300 and the operation during use are relatively simple and the cost is also relatively low. In this case, when it is necessary to adjust the position of the nose pad assembly 4 in the arrangement direction A of the first support 11 and the second support 12, the first knob 31 is rotated in the corresponding direction. The first knob 31 drives the first lead screw 21 to rotate, and then the first lead screw 21 drives the nose pad assembly 4 to move in the corresponding direction. For example, the second end of the first lead screw 21 can include a first section connected to the second support 12 and a second section located on the side opposite to the first support 11. The first knob 31 can be fixed to the second section.

[0037] Figure 4 Another structure schematic view of the intelligent glasses nose pad device 300 is provided in the present application. As shown in Figure 4In other implementations, the first driving assembly 3 can include a first motor 32, and a power output shaft of the first motor 32 is fixedly connected with the second end of the first screw rod 21. In this case, the manual operation of the user can be reduced, and the user can have a more convenient experience. In this case, when the position of the nose pad assembly 4 in the arrangement direction A of the first support 11 and the second support 12 needs to be adjusted, the first motor 32 is actuated to drive the first screw rod 21 to rotate, and then the first screw rod 21 drives the nose pad assembly 4 to move in the corresponding direction.

[0038] Of course, the linear transmission assembly 2 and the first driving assembly 3 are not limited to the above-mentioned manner. For example, in other embodiments, the linear transmission assembly can include a gear and a rack, the rack is slidingly arranged on the first base 1 and extends along the arrangement direction A of the first support 11 and the second support 12, and the gear is rotatably arranged on the first base 1 and is in meshing transmission with the rack. The nose pad assembly 4 is fixedly connected with the rack, and the first driving assembly 3 is connected with the gear and is used to drive the gear to rotate, so that the nose pad assembly 4 is driven by the rack to move along the arrangement direction A of the first support 11 and the second support 12.

[0039] When the user wears the smart glasses, in addition to the position of the nose pad assembly 4 in the arrangement direction A of the first support 11 and the second support 12 needs to be adjusted, the relative position of the nose pad assembly 4 and the nose of the user in the longitudinal direction can also need to be adjusted, so as to better adapt to the nose shape of the user, so that the position of the smart glasses can be more accurate and reliable, and then the user can have a better experience when wearing the smart glasses. In view of this, in some embodiments, the nose pad device 300 provided by the present application further includes a longitudinal adjustment mechanism 5 for adjusting the longitudinal position of the nose pad assembly 4. It is not difficult to understand that the relative position of the nose pad assembly 4 and the nose of the user in the longitudinal direction is also the relative position of the nose pad assembly 4 and the nose of the user in the direction perpendicular to the ground when the user wears the smart glasses.

[0040] Specifically, Figure 5 An exploded view of a nose pad device 300 in a smart glasses provided by the present application is shown. As Figure 4 and Figure 5As shown, the longitudinal adjusting mechanism 5 comprises a second base 51, a longitudinal transmission assembly, and a second driving assembly 53. The second base 51 is connected with the linear transmission assembly 2 and can move along the arrangement direction A of the first support 11 and the second support 12 under the driving of the linear transmission assembly 2. The longitudinal transmission assembly is arranged on the second base 51 and longitudinally extends. The second driving assembly 53 is in transmission connection with the longitudinal transmission assembly, and the longitudinal transmission assembly is connected with the nose pad assembly 4, so that the second driving assembly 53 can drive the nose pad assembly 4 to move longitudinally through the longitudinal transmission assembly.

[0041] In some embodiments, the longitudinal transmission assembly comprises a second lead screw 521 and a second guide rod 522 which are parallel to each other. Both the second lead screw 521 and the second guide rod 522 longitudinally extend and are arranged on the second base 51, and the second lead screw 521 is in rotational connection with the second base 51. The nose pad assembly 4 is in threaded connection with the second lead screw 521 and in sliding connection with the second guide rod 522. For example, as shown in Figure 5 , the second base 51 comprises a first bottom plate 511, and a third support 512 and a fourth support 513 which are arranged on the first bottom plate 511 and away from the first base 1. Both ends of the second guide rod 522 are connected with the third support 512 and the fourth support 513 respectively, and both ends of the second lead screw 521 are in rotational connection with the third support 512 and the fourth support 513 respectively. The end of the second lead screw 521 which is connected with the third support 512 protrudes out of the third support 512 and is in transmission connection with the second driving assembly 53. In specific implementation, the second guide rod 522 can be one or two parallel rods. When the second guide rod 522 is two parallel rods, the two second guide rods 522 are arranged on both sides of the second lead screw 521, and the nose pad assembly 4 is in sliding connection with both of the second guide rods 522 to increase the stability of the nose pad assembly 4 during movement. In addition, in specific implementation, the first end of the second lead screw 521 can be connected with the third support 512 through a bearing, and the second end of the second lead screw 521 is inserted into a hole in the fourth support 513. The size and surface roughness of the second end of the second lead screw 521 and the hole in the fourth support 513 can be designed to reduce the possibility of accidental rotation of the second lead screw 521, so that the second lead screw 521 can rotate as much as possible only under the action of the second driving assembly 53.

[0042] Figure 6 An exploded view of the nose pad device 300 of the intelligent glasses, Figure 7 An exploded view of the nose pad device 300 of the intelligent glasses, Figure 6 A cross-sectional view of the nose pad device 300. Figure 6 A cross-sectional view of the nose pad device 300 of the intelligent glasses, Figure 5 The difference between the nose pad device 300 and the nose pad device 300' lies in the guiding structure of the longitudinal movement of the nose pad assembly. Specifically, please refer toFigure 6 and Figure 7 In some other embodiments, the nose pad assembly 4 comprises a reversed U-shaped connecting piece 41 and two nose pads 42, wherein the reversed U-shaped connecting piece 41 comprises a first part 411 and two second parts 412 connected to two ends of the first part 411; the second base 51 has a containing space, a bottom of the containing space is formed with through holes for the two second parts 412 to pass through; the second screw rod 521 and the first part 411 are both located in the containing space, and the second screw rod 521 is rotationally arranged on the second base 51, the first part 411 is threadedly connected with the second screw rod 521 and is slidingly connected with the second base 51; the two second parts 412 both extend to the outside of the containing space through the through holes, and the two nose pads 42 are oppositely arranged and respectively connected with the two second parts 412 away from the first part 411. It is not difficult to understand that the two nose pads 42 are oppositely arranged, and the arrangement direction of the two nose pads 42 is parallel to the width direction of the lens 200 of the smart glasses (that is, the width direction of the face of the user).

[0043] Please continue to refer to Figure 6 and Figure 7 The second base 51 comprises a bottom shell and a first cover plate 514, and the bottom shell and the first cover plate 514 cooperatively enclose the containing space. One of the bottom shell and the first cover plate 514 is provided with a plurality of positioning protrusions a, and the other is provided with positioning holes corresponding to the positioning protrusions a, the positioning protrusions a are clamped in the corresponding positioning holes, so as to fix the first cover plate 514 on the bottom shell. Exemplarily, the first cover plate 514 and the bottom shell are both rectangular, and the first cover plate 514 is connected with a connecting lug 5141 perpendicular to the first cover plate 514 at each of the four corners, and each connecting lug 5141 is provided with a positioning hole. The bottom shell comprises two first side plates 515 opposite to each other, a second bottom plate 516 connected between the two first side plates 515, and a fifth support 517 and a sixth support 518, the fifth support 517 and the sixth support 518 are arranged in a direction away from the first base, and the two ends of the second screw rod 521 are rotationally connected with the fifth support 517 and the sixth support 518 respectively, and the end of the second screw rod 521 connected with the fifth support 517 protrudes out of the fifth support 517 and is drivingly connected with the second driving assembly 53. The two first side plates 515 are provided with positioning protrusions a corresponding to the corresponding positioning holes, and the positioning protrusions a are clamped in the corresponding positioning holes. The first part 411 of the reversed U-shaped connecting piece 41 is slidingly connected with the first cover plate 514 and the second bottom plate 516, so as to realize the guiding effect during the movement of the nose pad assembly. In order to facilitate the connecting lug to be sleeved into the positioning protrusion, the size of the positioning protrusion gradually decreases in the direction away from the first side plate 515 connected with the positioning protrusion. Figure 8 For Figure 6 the enlarged view of the nose pad device 300 shown in Figure 8As shown, the positioning protrusion has a cross-sectional shape of a direct trapezoid in a plane perpendicular to the first side plate 515. In addition, the second base 51 can further include a connecting head 519 connected to the bottom shell, and the connecting head 519 is connected to the linear transmission assembly 2.

[0044] It is worth noting that the second part 412 of the inverted U-shaped connecting piece 41 can be directly connected to the nose pad 42, or can be connected to the nose pad 42 through a transition piece 44. As shown in the drawings, Figure 6 As shown, the nose pad assembly 4 includes two transition pieces 44, each of which is connected to one second part 412 at one end and connected to the nose pad 42 at the other end. In the direction away from the first base 1, the distance between the two transition pieces 44 gradually increases. It should be understood that the shape of the transition piece 44 is not limited to Figure 6 As shown, the linear type, or can include a curved portion, etc., will not be described in detail here.

[0045] When the above two schemes are adopted, the second drive assembly 53 can have various implementations. For example, in one specific implementation, the second drive assembly 53 includes a second knob fixedly connected to one end of the second lead screw 521. In this scheme, the assembly and operation of the nose pad device 300 during use are relatively simple, and the cost is also relatively low. In this case, when the longitudinal position of the nose pad assembly 4 needs to be adjusted, the second knob is turned in the corresponding direction, the second lead screw 521 is driven to rotate by the second knob, and then the nose pad assembly 4 is driven to move in the corresponding direction by the second lead screw 521. Another specific implementation is as shown in the drawings, Figure 7 As shown, the second drive assembly 53 includes a second motor 531, and the power output shaft of the second motor 531 is fixedly connected to one end of the second lead screw 521. In this scheme, the user's manual operation can be reduced, and a more convenient user experience can be provided. In this case, when the longitudinal position of the nose pad assembly 4 needs to be adjusted, the second motor 531 is actuated, the second lead screw 521 is driven to rotate by the second motor 531, and then the nose pad assembly 4 is driven to move in the corresponding direction by the second lead screw 521.

[0046] The setting of the longitudinal transmission assembly and the second drive assembly 53 is not limited to the above manner. For example, in other embodiments, the longitudinal movement assembly can include a gear and a rack, the rack is slidingly arranged on the second base 51 and extends in the longitudinal direction, and the gear is rotatably arranged on the second base 51 and is in meshing transmission with the rack. The nose pad assembly 4 is fixedly connected to the rack, and the second drive assembly 53 is connected to the gear and is used to drive the gear to rotate, so that the nose pad assembly 4 moves in the longitudinal direction under the driving of the rack.

[0047] The longitudinal adjustment mechanism 5 can also have other implementations. Specifically, Figure 9 A structure schematic view of a longitudinal adjustment mechanism 5 in an intelligent glasses provided by the present application,Figure 10 As shown in the exploded view of the longitudinal adjustment mechanism 5, Figure 9 As shown in the exploded view of the longitudinal adjustment mechanism 5, Figure 11 As shown in the exploded view of the longitudinal adjustment mechanism 5, Figure 9 As shown in the exploded view of the longitudinal adjustment mechanism 5, Figures 9-11 As shown in the exploded view of the longitudinal adjustment mechanism 5, The first positioning portion 621 or the second positioning portion 43 is a plurality of positioning portions arranged along the longitudinal direction, and the matching relationship between the first positioning portion 621 and the second positioning portion 43 is different, and the longitudinal position of the nose pad assembly 4 relative to the third base 62 is different. The two nose pads 42 are always exposed to the third base 62 in the longitudinal direction. The trigger assembly 61 is used to trigger the second positioning portion 43 to separate from the first positioning portion 621. When the longitudinal position of the nose pad assembly 4 needs to be adjusted, the second positioning portion 43 is separated from the first positioning portion 621 by the trigger assembly 61, then the nose pad assembly 4 is manually moved to the appropriate position, and finally the trigger assembly 61 is reset, and the second positioning portion 43 is connected to the first positioning portion 621.

[0048] In a specific implementation, the third base 62 includes two first plates 622 opposite in the arrangement direction of the two nose pads 42, and the two first plates 622 are each provided with a first positioning portion 621. The inverted U-shaped connecting piece 41 includes a first portion 411 and two second portions 412 connected to both ends of the first portion 411, and the two second portions 412 are each provided with a second positioning portion 43. That is, the second positioning portion 43 on the two second portions 412 of the inverted U-shaped connecting piece 41 is connected to the first positioning portion 621 on the corresponding first plate 622 to fix the nose pad assembly 4, which can make the position of the nose pad assembly 4 more reliable, and thus make the position of the smart glasses more accurate and reliable when the smart glasses are worn by the user.

[0049] In specific implementation, one of the first positioning portion 621 and the second positioning portion 43 can be a positioning hole, and the other can be a positioning protrusion, and the positioning hole is connected to the corresponding positioning protrusion. For example, please refer to Figure 10The bottom of the accommodating space formed by the third base 62 is open, and a plurality of positioning holes are arranged on the two first plate bodies 622 of the third base 62, and the positioning holes on the two first plate bodies 622 are opposite to each other. The two second parts 412 of the inverted U-shaped connecting piece 41 are each provided with a positioning protrusion, and the positioning protrusions on the two second parts 412 are opposite to each other. When the positioning protrusions on the inverted U-shaped connecting piece 41 are clamped with the different positioning holes on the third base 62, the longitudinal positions of the nose pads 42 relative to the third base 62 are different.

[0050] Please refer to Figure 10 and Figure 11 The third base 62 includes the two first plate bodies 622, a second plate body 623 connected between the two first plate bodies 622, and a third plate body opposite to the second plate body. The third plate body 624 is connected with the two first plate bodies, the second plate body 623 is opposite to the third plate body 624, and the second plate body 623 or the third plate body 624 is provided with a through hole. The trigger assembly 61 includes a button 611 and an elastic member 612. The button 611 includes a pressing part 6111 located at least partially in the through hole and two converging side plates 6112 connected to the inner side of the pressing part 6111. The two converging side plates 6112 are arranged opposite to each other in the arrangement direction of the two nose pads 42, and are respectively inserted between the two second parts 412 and the corresponding first plate bodies 622. In the direction away from the pressing part 6111, the distance between the ends of the two converging side plates 6112 away from the pressing part 6111 gradually increases. In this way, in the process of pressing the button 611, the two converging side plates 6112 can make the two second parts 412 of the inverted U-shaped connecting piece close to each other (as shown by the dashed line in Figure 11 ), the distance between the corresponding second part 412 and the first plate body 622 gradually increases, and finally the first positioning part 621 and the second positioning part 43 connected with the first positioning part 621 are separated, so that the longitudinal position of the nose pad assembly can be adjusted.

[0051] The elastic member 612 is arranged in the accommodating space of the third base 62 and abuts against the inner surface of the pressing part 6111 and the third base 62. When the elastic member 612 is in a natural state, the first positioning part is clamped with the corresponding second positioning part. In the process of being compressed by the button, the first positioning part can be separated from the corresponding second positioning part.

[0052] Exemplarily, the two first plate bodies 622 and the second plate body 623 connected between the two first plate bodies 622 can be a one-piece structure, and the third plate body 624 can be connected to the structure by buckling. The third plate body 624 is provided with a through hole for cooperating with the pressing portion 6111 of the button 611, and an elastic member is arranged between the pressing portion 6111 and the second plate body 623. The elastic member 612 can be a spring or a metal spring piece. When the longitudinal position of the nose pad assembly 4 needs to be adjusted, the two converging side plates 6112 can be driven to move away from the pressing portion 6111 of the button 611 by pressing the button 611, so as to separate the first positioning portion 621 and the second positioning portion 43 connected with the first positioning portion 621 through the two converging side plates 6112.

[0053] It should be noted that the inverted U-shaped mentioned in the embodiment should be understood in a broad sense. As long as the connecting member includes two second parts opposite in the arrangement direction of the two nose pads and a first part connecting the two second parts, it can be understood as the inverted U-shaped connecting member mentioned in the embodiment. That is, the first part can also be a curved line or a broken line.

[0054] For ease of understanding, the transverse adjustment mechanism is defined below to include the first base, the linear transmission assembly and the first driving assembly, and then the transverse adjustment mechanism and the longitudinal adjustment mechanism in the application can be combined arbitrarily. For example, Figure 4 and Figure 6As shown, in the lateral adjustment machine, the linear transmission assembly 2 includes a first lead screw 21 and a first guide rod 22 that are parallel to each other. The first guide rods 22 are two parallel to each other, and the two first guide rods 22 are distributed on both sides of the first lead screw 21. The first drive assembly 3 includes a first motor 32, which is fixedly connected to the second end of the first lead screw 21 and is used to drive the first lead screw 21 to rotate. The longitudinal adjustment mechanism 5 includes a second base 51, a longitudinal transmission assembly and a second drive assembly 53, wherein the longitudinal transmission assembly includes a second lead screw 521, and the second drive assembly 53 includes a second motor 531. The second base 51 is connected to the first lead screw 21 and the first guide rod 22. The nose pad assembly 4 includes an inverted U-shaped connector 41 and two nose pads 42. The inverted U-shaped connector 41 includes a first part 411 and two second parts 412 connected to the two ends of the first part 411. The second base 51 has a accommodating space, and the second lead screw 521 and the first part 411 are both located in the accommodating space, and the second lead screw 521 is rotatably arranged on the second base 51, and the first part 411 is threadedly connected to the second lead screw 521 and slidably connected to the second base 51. The power output shaft of the second motor 531 is fixedly connected to one end of the second lead screw 521. In other words, the lateral adjustment mechanism and the longitudinal adjustment mechanism are both electrically adjustable, and the lateral adjustment mechanism and the longitudinal adjustment mechanism are both electrically adjustable, which can help the user automatically adjust the lateral and longitudinal positions of the nose pads, and the adjustment accuracy is higher. In this solution, when the user needs to adjust the lateral and longitudinal positions of the nose pad assembly, the user inputs the nose pad adjustment information, and the corresponding first and second motors are activated until the human body senses that the nose pads are adjusted into place, and the corresponding first and second motors stop. Otherwise, the adjustment continues.

[0055] like Figure 3 As shown, in the lateral adjustment mechanism, the linear transmission assembly 2 includes a first lead screw 21 and a first guide rod 22 that are parallel to each other. The first guide rods 22 are two parallel first guide rods 22, and the two first guide rods 22 are distributed on both sides of the first lead screw 21. The first lead screw 21 includes a first end and a second end. The first end of the first lead screw 21 is rotatably connected to the first support 11, and the second end of the first lead screw 21 is rotatably connected to the second support 12. The first drive assembly 3 includes a first knob 31, which is fixedly connected to the second end of the first lead screw 21 and is used to drive the first lead screw 21 to rotate. The longitudinal adjustment mechanism 5 includes a third base 62 and a trigger assembly 61. In other words, both the lateral adjustment mechanism and the longitudinal adjustment mechanism are manually adjusted.

[0056] Of course, in other embodiments, the lateral adjustment mechanism and the longitudinal adjustment mechanism may also be other combinations, for example: the lateral adjustment mechanism may be manually adjusted, and the longitudinal adjustment mechanisms may be electrically adjusted; or, the lateral adjustment mechanism may be electrically adjusted, and the longitudinal adjustment mechanisms may be manually adjusted, which will not be explained one by one here.

[0057] Obviously, many modifications and variations of the present application are possible in light of the above teachings. It is, therefore, to be understood that within the scope of the appended claims and their equivalents, the application can be practiced otherwise than as specifically described.
