Description

Technical Field

[0001] This application belongs to the technical field of vehicle lighting equipment, specifically relating to a lamp and a vehicle. Background Technology

[0002] In automotive lighting, the dimming components are used to adjust the beam angle of the lights, providing the driver with a better driving view.

[0003] In related technologies, lighting fixtures include an adjusting screw and a dimming assembly. The rotation of the adjusting screw drives the dimming assembly to reciprocate, thereby adjusting the beam angle of the lighting fixture. However, because the position of the dimming assembly is adjusted solely by the adjusting screw, the cantilever length of the adjusting screw is relatively long, making the adjusting screw prone to deformation and failure. Utility Model Content

[0004] Based on the above-mentioned technical problems, this application provides a lamp and a vehicle, which aims to at least partially solve the technical problem that the cantilever length of the lamp's adjusting screw is too long, causing the adjusting screw to easily deform and fail.

[0005] In a first aspect, this application provides a lamp fixture, the lamp fixture comprising: a lamp housing having a built-in receiving cavity; a sliding member movably disposed within the receiving cavity along a predetermined direction; a dimming assembly disposed within the receiving cavity and connected to the sliding member; and an adjusting screw, partly disposed within the receiving cavity and the other part rotatably passing through the lamp housing, the adjusting screw and the sliding member being arranged sequentially along the predetermined direction, the adjusting screw having a threaded portion, the threaded portion being threadedly connected to the sliding member to drive the sliding member to move relative to the lamp housing along the predetermined direction.

[0006] The lamp provided in this application features a sliding member that is movably positioned within a receiving cavity along a set direction. The adjusting screw has a threaded portion that is threadedly connected to the sliding member. Therefore, by controlling the rotation of the adjusting screw, the sliding member can be driven to move back and forth within the lamp housing along the set direction. Since the dimming component is connected to the sliding member, its position within the lamp housing is also adjusted accordingly, thereby achieving the purpose of adjusting the light emission angle of the lamp beam. Furthermore, because the adjusting screw and sliding member are arranged sequentially along the set direction, compared to a method where the adjusting component is directly connected to the adjusting screw, this application, through the intermediate role of the sliding member, can reduce the length of the adjusting screw while achieving the desired light emission angle. This avoids the phenomenon of the adjusting screw easily deforming and failing after prolonged use, thus ensuring the normal operation of the lamp.

[0007] In conjunction with the first aspect, in some possible implementations, the luminaire further includes a connector, an adjustment channel is defined between the slider and the connector, the adjustment channel extends along the set direction, and the threaded portion is threaded through the adjustment channel.

[0008] In conjunction with the first aspect, in some possible implementations, the sidewall of the adjustment channel is provided with a first mounting opening; the connector connects to the sliding member, the connector including a web, at least a portion of the web being recessed into the adjustment channel through the first mounting opening and pressing the threaded portion.

[0009] In conjunction with the first aspect, in some possible implementations, at least a portion of the web is provided with threads that mate with the threaded portion.

[0010] In conjunction with the first aspect, in some possible implementations, the sliding member includes a protrusion, the protrusion having the adjustment channel along the set direction, and the protrusion having connecting sidewalls located on both sides of the first assembly port; the connecting member further includes two wing plates, the two wing plates being respectively connected to both sides of the web plate, the wing plates and the connecting sidewalls being arranged in a one-to-one correspondence, the wing plates overlapping the outer side of the corresponding connecting sidewalls, one of the corresponding wing plates and the connecting sidewalls being provided with a positioning port, and the other being provided with a positioning protrusion, the positioning protrusion being inserted into the positioning port.

[0011] In conjunction with the first aspect, in some possible implementations, both of the opposite sides of the two wing plates are connected with reinforcing flanges.

[0012] In conjunction with the first aspect, in some possible implementations, the connector is elastic.

[0013] In conjunction with the first aspect, in some possible implementations, the adjusting screw further includes a transmission part that passes through the lamp housing; the lamp further includes a transmission component that is disposed outside the lamp housing and connected to the transmission part to drive the adjusting screw to rotate.

[0014] In conjunction with the first aspect, in some possible implementations, the transmission component includes a first bevel gear and a second bevel gear that cooperate with each other, the first bevel gear being connected to the transmission part, and the second bevel gear being rotatably disposed.

[0015] In conjunction with the first aspect, in some possible implementations, the lamp further includes: a support member connected to the mounting side wall of the lamp housing and located on the outside of the lamp housing; the support member is provided with a limiting channel; the inner wall of the limiting channel is recessed to form a limiting groove; the outer peripheral surface of the second bevel gear is provided with a limiting protrusion; the second bevel gear passes through the limiting channel; at least a portion of the limiting protrusion is rotatably disposed in the limiting groove.

[0016] In conjunction with the first aspect, in some possible implementations, a seal is provided between the transmission part and the lamp housing.

[0017] In a second aspect of this application, a vehicle is also provided, the vehicle including the lighting fixtures described in the second aspect.

[0018] The lamps described in the first aspect and the vehicles equipped with such lamps can reduce the cantilever length of the adjusting screw while achieving the desired beam angle adjustment. This avoids the phenomenon that the adjusting screw is prone to deformation and failure after prolonged use, thus ensuring the normal operation of the lamps and demonstrating excellent practicality.

[0022] The technical solutions in this application will now be clearly and thoroughly described with reference to the accompanying drawings. Specifically, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0024] Today, vehicles are the most important means of transportation for every household. Their widespread use has enriched human life and accelerated its pace. Vehicle lights provide illumination, lighting the way forward and ensuring driving safety. The high and low beams of these lights, as the primary lighting function of a vehicle, can be adjusted through related lighting fixtures to change the angle of the beam in all directions, providing the driver with a better field of vision.

[0025] In related technologies, the luminaire includes a dimming bracket and a dimming component. The dimming component is built into the lamp housing of the luminaire and includes a ball head screw. The light source of the luminaire is mounted on the dimming bracket. The dimming bracket cooperates with the ball head screw to change the position and orientation of the dimming bracket, thereby achieving the purpose of adjusting the light beam.

[0026] During the installation and maintenance of lighting fixtures, adjusting screws are often used to directly drive the dimming components to move back and forth. This results in a relatively long adjusting screw, with most of it in a cantilever position. However, due to the relatively weak strength of the adjusting screw, it is prone to deformation and failure when kept in a cantilever position for a long time, which in turn affects the dimming function of the lighting fixture.

[0027] Based on the aforementioned technical problems, in the first aspect of this application, a lamp is provided, wherein a sliding member is added to the lamp in addition to the adjusting screw. By utilizing the cooperation between the sliding member and the adjusting screw, the dimming function of the lamp can be realized, while the cantilever length of the adjusting screw can be reduced, thus avoiding the problem of deformation and failure caused by the adjusting screw being too long.

[0028] Figure 1 A schematic diagram of the structure of a lamp 10 according to one or more embodiments of this application is shown. Figure 2 It shows Figure 1 A schematic diagram of the exploded structure. Combined with... Figure 1 as well as Figure 2 The lamp 10 provided in this application includes a lamp housing 100, a dimming assembly 200, a sliding member 300, and an adjusting screw 400. The lamp housing 100 has a built-in receiving cavity 110, and the sliding member 300 is movably disposed in the receiving cavity 110 along a set direction. The dimming assembly 200 is disposed in the receiving cavity 110 and connected to the sliding member 300. Part of the adjusting screw 400 is disposed in the receiving cavity 110, and the other part rotatably passes through the lamp housing 100. The adjusting screw 400 and the sliding member 300 are arranged sequentially along the set direction. The adjusting screw 400 is provided with a threaded portion 410, and the threaded portion 410 is threadedly connected to the sliding member 300 to drive the sliding member 300 to move relative to the lamp housing 100 along the set direction.

[0029] The lamp 10 provided in this application features a sliding member 300 that is movably disposed within the receiving cavity 110 of the lamp housing 100 along a set direction. The adjusting screw 400 has a threaded portion 410, which is threadedly connected to the sliding member 300. Therefore, by controlling the rotation of the adjusting screw 400, the sliding member 300 can be driven to move back and forth within the lamp housing 100 along the set direction. Since the dimming component 200 is connected to the sliding member 300, the position of the dimming component 200 within the lamp housing 100 is also adjusted accordingly, thereby achieving the purpose of adjusting the light beam's output angle. Furthermore, because the adjusting screw 400 and the sliding member 300 are arranged sequentially along the set direction, compared to the method where the dimming component 200 is directly connected to the adjusting screw 400, this application can, with the help of the sliding member 300, reduce the length of the adjusting screw 400 while achieving the desired light beam output angle adjustment. This avoids the phenomenon of the adjusting screw 400 easily deforming and failing after prolonged use, thus ensuring the normal operation of the lamp 10.

[0030] Figure 3 It shows Figure 1 A frontal view diagram. Combined with... Figure 3 For ease of description, the lamp 10 of this application is now defined to have a length direction Y, a width direction X, and a thickness direction Z, wherein the length direction Y is... Figure 3 The Y direction shown is the vertical direction, and the width direction X is... Figure 3 The X direction shown is the left-right direction, and the Z direction of thickness is... Figure 3 The Z direction shown is the front-to-back direction.

[0031] Combination Figure 3 In some embodiments, the width direction X of the slider 300 is adapted to the width direction X of the receiving cavity 110 of the lamp housing 100, and the length direction Y of the slider 300 is smaller than the length direction Y of the receiving cavity 110 of the lamp housing 100, so as to provide space for the reciprocating movement of the slider 300, so that the slider 300 can move back and forth in the lamp housing 100 along the length direction Y under the drive of the adjusting screw 400. The length direction Y is the aforementioned set direction.

[0032] Combination Figure 1 as well as Figure 2 In some embodiments, a guide mechanism 500 is also provided between the slider 300 and the lamp housing 100. The guide mechanism 500 includes a slide rail 510 and a slide groove 520. The slide rail 510 is connected to one of the slider 300 and the lamp housing 100, and the other of the slider 300 and the lamp housing 100 has a slide groove 520. The slide rail 510 is slidably disposed in the slide groove 520 to provide guidance for the reciprocating movement of the slider 300 and ensure that the slider 300 moves reciprocally in a set direction. Figure 4 It shows Figure 1The structural diagram of the slider 300 in the diagram is shown in the figure. Figure 1 , Figure 2 as well as Figure 4 For example, three slide grooves 520 are provided. Two slide grooves 520 are located on both sides of the lamp housing 100 in the width direction X, and another slide groove 520 is provided on the bottom surface of the lamp housing 100. Correspondingly, three slide rails 510 are also provided. The side portion of the slider 300 in the width direction X can be configured as a slide rail 510, and the bottom of the slider 300 is provided with a protrusion to serve as another slide rail 510. The slide rails 510 and slide grooves 520 are provided one-to-one. The slide rails 510 are slidably disposed in the corresponding slide grooves 520 to guide the reciprocating movement of the slider 300. In other configurations, the slide rails 510 can also be connected to the inner side of the bottom wall of the lamp housing 100, and the slide grooves 520 are disposed at the bottom of the slider 300. By sliding the slider 300 in the slide grooves 520, the reciprocating movement of the slider 300 can also be guided.

[0033] Combination Figures 1-3 In some embodiments, two dimming components 200 are provided, both of which are disposed on the same side of the slider 300 along the length direction Y. For example, the slider 300 has a first side and a second side along the length direction Y. The first side of the slider 300 is approximately inclined. The two dimming components 200 are respectively connected to both ends of the first side of the slider 300 and are located at the same height. In other configurations, one or more dimming components 200 may be provided, such as three or four, with multiple dimming components 200 spaced apart from each other on the first side of the slider 300. This application does not impose any limitations on this.

[0034] Combination Figures 1-3 In some embodiments, the dimming assembly 200 includes a ball head screw 210. During vehicle installation or lamp maintenance, the adjusting screw 400 is rotated, causing the sliding member 300 and the ball head screw 210 to move synchronously back and forth, thereby moving the dimming bracket to change its position and orientation, so that the lamp source of the dimming bracket is properly installed. When the lamp 10 is installed on the vehicle body, the ball head screw 210 and the dimming bracket remain relatively fixed to maintain the proper position and orientation of the dimming bracket, ensuring that the lamp source of the lamp 10 is in the set position and orientation. This is continuous and combined. Figure 4 The sliding member 300 includes a mounting part 330, and the mounting part 330 and the ball head screw 210 are provided in a one-to-one correspondence. The ball head screw 210 is assembled onto the mounting part 330.

[0035] In some embodiments, the dimming assembly 200 also includes a drive motor (not shown), which is fixedly mounted on the sliding member 300. A ball-head screw 210 is connected to the drive motor and can be movably positioned on the sliding member 300 in a set direction under the drive of the drive motor. During vehicle installation or lamp maintenance, the adjustment screw 400 is rotated, causing the sliding member 300 and the dimming assembly 200 to move synchronously back and forth, thereby causing the dimming bracket to move and change its position and orientation, thus aligning the lamp source of the lamp 10. When the lamp 10 is mounted on the vehicle body, the drive motor can be controlled to move, causing the ball-head screw 210 to move reciprocally in a set direction, thereby causing the dimming bracket to move and change its position and orientation, which in turn changes the position and orientation of the lamp source on the dimming bracket, adjusting the light emission angle of the beam emitted by the lamp source 10. In this case, the lamp 10 can be a high beam or low beam lamp.

[0036] Figure 5 This shows a structural schematic diagram of the slider 300 from another perspective. Figure 6 An assembly diagram of the slider 300 and the adjusting screw 400 is shown. (Combined with...) Figure 5 as well as Figure 6 In some embodiments, the lamp 10 further includes a connector 600, and an adjustment channel 321 is defined between the slider 300 and the connector 600. The adjustment channel 321 extends along a set direction, that is, the adjustment channel 321 passes through the length direction Y. The threaded portion 410 of the adjustment screw 400 is threaded through the adjustment channel 321. By controlling the rotation of the adjustment screw 400, the slider 300 can be driven to move back and forth along the set direction, thereby driving the position of the dimming assembly 200 inside the lamp housing 100, changing the position and orientation of the dimming bracket, and thus achieving the purpose of adjusting the beam.

[0037] Combination Figure 5 as well as Figure 6In some embodiments, the slider 300 includes a slider 310 and a protrusion 320. The dimming assembly 200 is connected to one side of the slider 310 in the length direction Y. The mounting part 330 can be connected to one side of the slider 310 in the thickness direction Z by means of integral molding or the like. The protrusion 320 can be connected to the other side of the slider 310 in the thickness direction Z by means of integral molding or the like. The protrusion 320 is close to the other side of the slider 310 in the length direction Y. The protrusion 320 has the above-mentioned adjustment channel 321 opened in the set direction. The threaded part 410 of the adjustment screw 400 is threaded through the adjustment channel 321 so that the adjustment screw 400 and the slider 310 of the slider 300 are misaligned in the thickness direction Z so as to effectively utilize the space in the thickness direction Z inside the lamp housing 100. For example, the slider 310 has a box-shaped structure, that is, at least part of the interior of the slider 310 is hollow, so as to reduce the weight of the slider 300 to a certain extent. Correspondingly, the weight of the lamp 10 is also reduced, making the lamp 10 lightweight. The protrusion 320 and the slider 310 are integrally formed to ensure that the slider 300 has sufficient strength for use.

[0038] Combination Figure 5 as well as Figure 6 In some embodiments, the side wall of the adjustment channel 321 is provided with a first assembly port 322, and the connector 600 is connected to the sliding member 300. Figure 7 A structural schematic diagram of connector 600 is shown, combined with Figure 7 The connecting member 600 includes a web 610, at least a portion of which is recessed into the adjusting channel 321 through a first mounting opening 322 and presses against the threaded portion 410. This arrangement allows for the threaded connection between the threaded portion 410 of the adjusting screw 400 and the adjusting channel 321, and also enables the thread within the adjusting channel 321 to be machined through the first mounting opening 322 during the manufacturing of the sliding member 300, facilitating the production of the sliding member 300 and demonstrating excellent practicality.

[0039] Combination Figures 5-7 In some embodiments, the side of the adjustment channel 321 facing away from the slider 310 is open, that is, the bottom surface of the adjustment channel 321 is open, serving as the aforementioned first mounting opening 322. This makes the adjustment channel 321 generally U-shaped, with the middle portion of the web 610 recessed into the adjustment channel 321 through the middle part of the first mounting opening 322, thus pressing against the threaded portion 410 of the adjustment screw 400. When the adjustment screw 400 is driven to rotate, it can drive the threaded protrusion 320 to move back and forth, thereby driving the dimming assembly 200 on the slider 300 to move back and forth, achieving the technical purpose of dimming.

[0040] In some embodiments, at least a portion of the web 610 is provided with threads that mate with the threaded portion 410, so that the web 610 is also threadedly connected to the threaded portion 410 of the adjusting screw 400. This ensures that the forces exerted by the adjusting screw 400 on the connector 600 with the web 610 and the sliding member 300 are balanced, resulting in rolling friction between the web 610 and the threaded portion 410 of the adjusting screw 400. This avoids the technical problem of poor rotation of the adjusting screw 400 caused by static friction between the web 610 and the threaded portion 410 of the adjusting screw 400. Exemplarily, the middle portion of the web 610 has an arc shape adapted to the threaded portion 410 of the adjusting screw 400, and the middle portion of the web 610 is provided with threads that mate with the threaded portion 410.

[0041] Figure 8 This diagram shows the assembly schematic of the connector 600 and the sliding member 300. Figure 8 In some embodiments, the protrusion 320 also has connecting sidewalls 323 located on both sides of the first assembly port 322. The sidewalls on both sides of the first assembly port 322 and the slider 310 enclose an adjustment channel 321. The connector 600 also includes two wing plates 620, which are respectively connected to both sides of the web plate 610. The wing plates 620 and the sidewalls are arranged in a one-to-one correspondence. The wing plates 620 overlap the outer side of the corresponding connecting sidewalls 323. One of the corresponding wing plates 620 and the connecting sidewalls 323 is provided with a positioning port 621, and the other is provided with a positioning protrusion 324. The positioning protrusion 324 is inserted into the positioning port 621 so that the wing plate 620 and the corresponding connecting sidewalls 323 are relatively fixed, thereby keeping the connector 600 and the slider 300 fixed. For example, a positioning protrusion 324 is provided on the opposite side of the two connecting sidewalls 323, and a positioning port 621 is provided on the wing plate 620, that is, the wing plate 620 overlaps the outer side of the corresponding connecting sidewall 323; in other configurations, the positioning protrusion 324 is connected to the wing plate 620, and the positioning port 621 is opened in the corresponding connecting sidewall 323, all of which can realize the fixed assembly of the wing plate 620 on the corresponding connecting sidewall 323.

[0042] Combination Figure 8 In some embodiments, the outer surface of the positioning protrusion 324 is provided with a guide slope 325 to facilitate the insertion and assembly of the positioning protrusion 324 in the positioning port 621, thereby improving assembly efficiency.

[0043] Combination Figure 7 In some embodiments, both wing plates 620 are connected to opposite sides with reinforcing flanges 630, which may be arc-shaped to enhance the strength of the connector 600 itself.

[0044] In some embodiments, the connector 600 can be a one-piece molded structure, and the connector 600 has a certain degree of elasticity. The advantage of this configuration is that, during vehicle operation, the sliding member 300 equipped with the dimming component 200 may vibrate. The elastic connector 600 can buffer the vibration of the sliding member 300 to a certain extent, avoiding deformation and cracking of the adjusting screw 400 caused by the vibration of the sliding member 300, and improving the service life of the adjusting screw 400.

[0045] In some other embodiments, the adjustment channel 321 can also be directly formed on the slider 300, and the threaded part 410 of the adjustment screw 400 can be threaded through the adjustment channel 321, so that the threaded part 410 of the adjustment screw 400 can be threadedly connected to the slider 300.

[0046] Combination Figures 1-3 In some embodiments, the adjusting screw 400 further includes a transmission part 420, which passes through the lamp housing 100. The lamp 10 also includes a transmission component 700, which is disposed outside the lamp housing 100 and connected to the transmission part 420. This allows the transmission component 700 to be manually operated from outside the lamp housing 100 during lamp 10 installation and maintenance. The transmission component 700 drives the transmission part 420 and the threaded part 410 to rotate synchronously, thereby driving the sliding part 300 to move and adjust the position of the dimming component 200, thereby achieving dimming of the lamp 10 and facilitating the debugging of the lamp 10.

[0047] Combination Figures 1-3 In some embodiments, a seal 800 is provided between the transmission part 420 and the lamp housing 100 to keep the transmission part 420 and the lamp housing 100 sealed. Figure 9 An exploded view of the assembly of the transmission unit 420, lamp housing 100, and seal 800 is shown, in conjunction with... Figure 9For example, the lamp housing 100 includes a mounting sidewall 120, on which a mounting portion 121 is provided. The mounting portion 121 can protrude from the inner side of the mounting sidewall 120. The mounting portion 121 has a mounting hole 122 and a stop 123. The stop 123 is located inside the mounting portion 121 and is disposed at the edge of the mounting hole 122. The drive screw also includes a stop portion 430, which is an annular structure and is fixedly disposed on the circumferential surface of the transmission portion 420. The stop portion 430 is attached to the mounting sidewall 100. Inside the mounting part 121, the sealing element 800 is adapted to be disposed in the stop 123 and is limited by the stop part 430. The transmission part 420 of the adjusting screw 400 is interference-fitted through the sealing element 800 to fill the gap between the transmission part 420 and the lamp housing 100. When the transmission part 420 is driven to rotate, the sealing element 800 rotates synchronously to ensure the sealing of the inside of the lamp housing 100 and prevent moisture and other components from entering the inside of the lamp housing 100 through the gap between the transmission part 420 and the lamp housing 100.

[0048] Figure 10 A schematic diagram showing the assembly of the transmission component 700 on the lamp housing 100 is provided. Figure 10 In some embodiments, the mounting part 121 may also protrude from the outer side of the mounting sidewall 120. The mounting part 121 protrudes from the outer circumferential surface of the mounting sidewall 120 and is connected to the mounting sidewall 120 by a plurality of first reinforcing ribs 124 to improve the strength and service life of the mounting part 121 and avoid the problem of deformation and cracking caused by supporting the adjusting screw 400 for a long time.

[0049] Combination Figure 10 In some embodiments, the transmission component 700 includes two cooperating bevel gears, one of which is connected to the transmission part 420, and the other is rotatably disposed. Since the transmission component 700 is constructed from two cooperating bevel gears, it has a compact structure, enabling installation in space-constrained environments, and operates with low noise, improving the working environment. Furthermore, when the lamp 10 is mounted on the vehicle body, the length direction Y of the lamp housing 100 is arranged along the extension direction of the vehicle body, that is, the adjusting screw 400 is also arranged along the extension direction of the vehicle body. Through a pair of cooperating bevel gears, a driving force can be input to the adjusting screw 400 in a direction perpendicular to the extension direction of the adjusting screw 400, facilitating the adjustment of the lamp 10. For ease of description, one bevel gear is now defined as the first bevel gear 710, and the other bevel gear as the second bevel gear 720.

[0050] Combination Figure 10In some embodiments, the first bevel gear 710 is fixedly fitted onto the end of the transmission part 420 located on the outside of the lamp housing 100, and the second bevel gear 720 meshes with the first bevel gear 710. The lamp fixture 10 also includes a support member 900, which is connected to the mounting side wall 120 of the lamp housing 100 and located on the outside of the lamp housing 100. The support member 900 is provided with a limiting channel 910, the inner wall of which is recessed to form a limiting groove 920, which is annular. The outer circumferential surface of the second bevel gear 720 is provided with a limiting protrusion 721, and the second bevel gear 720 passes through the limiting channel 910. At least a portion of the limiting protrusion 721 is rotatably disposed in the limiting groove 920. This arrangement allows the second bevel gear 720 to be fitted onto the outside of the lamp housing 100. For example, the support member 900 and the lamp housing 100 are integrally formed. The periphery of the support member 900 is connected to the mounting side wall 120 by a plurality of second reinforcing ribs 125 to improve the strength of the support member 900 and the reliability of the connection with the lamp housing 100. The support member 900 is provided through in the thickness direction Z. The side of the support member 900 away from the mounting side wall 120 is open to serve as the second assembly port 930, so that the limiting channel 910 and the limiting groove 920 are both U-shaped. The second bevel gear 720 enters the limiting channel 910 in the support member 900 through the second assembly port 930 of the support member 900, and the limiting protrusion 721 on the periphery of the second bevel gear 720 is inserted into the limiting groove 920 so that the second bevel gear 720 rotates in the support member 900.
