Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] The core of this invention is to provide a decompressible rotary shaver that is entertaining while reducing the space occupied inside the casing.

[0050] For a specific embodiment of the decompressible rotary shaver provided by this utility model, please refer to... Figures 1 to 6 It includes a rotating body and at least one support member 9 located on the outside of the rotating body.

[0051] The rotating body includes a housing 2 and a protective cover 1 that are detachably connected along the first direction X. The housing 2 has a blade assembly 4 at the opening facing the protective cover 1. The protective cover 1 closes the opening. When shaving, the protective cover 1 is removed. After shaving, the blade assembly 4 can be closed by the protective cover 1.

[0052] The outer surface of the housing 2 is rotatably connected to the support member 9. Specifically, the support member includes a rotary bearing 91 connected to the outside of the housing 2 and a support body 913 connected to the rotary bearing 91. That is, the rotary bearing 91 is connected between the outer surface of the housing 2 and the support body 913 so that the rotating body can rotate relative to the support body 913, thereby the rotating body can rotate 360° relative to the support body 913.

[0053] like Figure 3 and Figure 5 As shown, the housing 2 is rotatably connected to the support member 9 on two opposite outer surfaces in the second direction Y, and the housing 2 can rotate independently relative to each support member 9. For example, in this embodiment, the support member 9 is a first support member 95, and in the first support member 95, the support body 913 is a support disk 94, which can specifically be a disk.

[0054] Additionally, the number of support members 9 can be one, two, three, or more. Users can simultaneously grasp two support members 9 and use them as fulcrums to rotate the body. When only one support member 9 is provided, refer to... Figure 13 In one embodiment, the support member 9 is annular, providing multiple fulcrums to drive the rotating body to rotate; alternatively, when the support member 9 is a disc-shaped structure, refer to... Figure 7 The shape of the support member 9 in the embodiment can also push the support member 9 upward or press the support member 9 downward, which can also horizontally push the rotating body to rotate without affecting the realization of its rotation function.

[0055] The aforementioned decompressible rotary shaver (hereinafter referred to as the shaver) combines functional use with a rotating function. Opening the protective cover 1 allows for basic shaving using the shaver head assembly 4. Furthermore, because each support plate 94 in each support member 9 is rotatably connected to the outside of the housing 2 via a rotary bearing 91, and each support plate 94 can rotate independently clockwise or counterclockwise, the shaver can rotate and tilt according to the angle of different parts of the face, chin, neck, etc., making it easier to rotate the shaver according to face shape and more convenient to use. Moreover, this external design of the support plates 94 and their separate connection ensures the integrity of the housing 2, improves its structural strength, reduces or eliminates seams, increases its impact resistance, and improves its sealing, waterproof, and dustproof performance. Additionally, the external rotatable connection of the support members 9 to the housing 2 reduces the space occupied inside the housing 2, increasing the flexibility of component arrangement within the housing 2. When not using the shaving function, you can hold the support to rotate the shaver's rotating body, or use the support frame to prop up the support to rotate the shaver's rotating body, ensuring the shaver's entertainment and stress-relieving functions.

[0056] Furthermore, the shaver also includes a head motor 6, which is built into the inner cavity of the housing 2 and is connected to the head assembly 4 for electrically driving the head assembly 4 to form an electric shaver.

[0057] To save costs, such as Figure 2 and Figure 3 As shown, only one blade motor 6 is provided. Compared to embodiments with multiple blade motors 6, the material cost is lower, the manufacturing process is simpler, and fewer process personnel are required, making the shaver more cost-effective in the market. Of course, in other embodiments, two or other numbers can also be provided.

[0058] Regarding the installation of the cutter head motor 6, such as Figure 2 As shown, in the third direction Z, the blade motor 6 is centrally located within the inner cavity of the housing 21. Since the blade motor 6 accounts for a large proportion of the weight of the entire shaver, its central location ensures the shaver's center of gravity is centered, significantly improving its balance and stability. This makes shaving easier and more comfortable for the user when holding the support disc 94 and rotating or tilting the shaver accordingly. Of course, in other embodiments, the blade motor 6 can also be located at the edge in the third direction Z, or centrally located in both the first direction X and the second direction Y.

[0059] Within the housing 2, the remaining space on either side of the head motor 6 in the third direction Z is utilized. Devices of similar or equal weight can be placed on either side to further ensure the shaver's center of gravity is centered. For example, the first side of the head motor 6 may have an energy module, specifically a battery, while the second side may have a battery or a support, with the same weight as the battery on the first side. The energy module powers one or more blades in a head assembly to move relative to the stationary blades and shave the beard.

[0060] In addition, such as Figure 3 As shown, in the second direction Y, the cutter head motor 6 fits against the inner wall of the inner cavity of the housing 2, so as to position the cutter head motor 6 in the second direction Y with the help of the housing 2.

[0061] It should be noted that in the description of the embodiments of this application, the first direction X, the second direction Y, and the third direction Z are three different directions, for example, they are perpendicular to each other. Figure 2 and Figure 3 For example, in this embodiment of the shaver, to facilitate the user to pinch the two support plates 94 from both sides of the shaver, the second direction Y corresponds to the thickness direction, and its size is smaller than the size of the shaver in the first direction X and the third direction Z. Figure 1As shown, to facilitate the rotation of the razor for shaving or as a fidget spinner, the cross-sectional shape of the razor perpendicular to the second direction Y can be circular. The diameter corresponding to both the first direction X and the second direction Y is the same. Furthermore, the rotation center line of the support disk 94 passes through the center of this circular cross-section and is parallel to the second direction Y. Of course, in other embodiments, the cross-sectional shape can also be rectangular, triangular, etc.

[0062] Furthermore, a battery 7 is also provided inside the housing 2 to power the electrical components of the shaver. One battery 7 can be selected as needed, or at least two batteries 7, such as two or three. Additionally, the shaver head motor 6 and other electrical components can be electrically connected to some or all of the batteries 7 as needed.

[0063] like Figure 2 As shown, in this embodiment, there are two batteries 7, namely a first battery 71 and a second battery 72 located on both sides of the blade motor 6 in the third direction Z. The first battery 71 and / or the second battery 72 are electrically connected to the blade motor 6. At this time, the first battery 71 and the second battery 72 can provide sufficient power to the blade motor 6 to ensure the battery life. The two batteries 7 distributed on both sides of the blade motor 6 can ensure the centrality of the shaver's center of gravity. Of course, in other embodiments, such as... Figure 8 As shown, battery 7 can also be set to only one.

[0064] To enable charging of battery 7, the housing 2 is provided with a charging connector 8 that is electrically connected to battery 7, which is exposed on the housing 2 for connection to a charger.

[0065] like Figure 2 As shown, on the third direction Z, a charging connector 8 is provided on the side of the housing 2 near the second battery 72. The first battery 71 and the second battery 72 are electrically connected to the charging connector 8 for charging the first battery 71 and the second battery 72. Specifically, the charging connector 8 includes a charging tail plug 82 and a tail plug waterproof ring 81 provided in the charging hole on the housing 2, with the tail plug waterproof ring 81 covering the outside of the charging tail plug 82.

[0066] To achieve on / off control of the shaver, such as Figure 2 As shown, on the third direction Z, a switch button 5 is provided on the side of the housing 2 near the first battery 71. The switch button 5 is electrically connected to the first battery 71 and the second battery 72. At this time, the switch button 5 and the support plate 94 are mounted on the surfaces of the housing 2 in different directions, which can improve the utilization rate of the surface of the housing 2 and prevent accidental activation of the switch button 5 when the support plate 94 rotates relative to the housing 2.

[0067] Specifically, such as Figure 2As shown, a button hole is provided on the housing 2, and the switch button 5 is connected to the button hole. The button hole is sealed by the switch waterproof ring 52 and the waterproof pressure plate 53.

[0068] Specifically, such as Figure 2 As shown, in the inner cavity of the housing 2, on the third direction Z, a circuit board 51 is also provided between the first battery 71 and the switch button 5, and the switch button 5 is electrically connected to the first battery 71 and the second battery 72 through the circuit board 51 to realize switch control.

[0069] Of course, in other embodiments, the switch button 5 and the charging connector 8 can also be located in other positions. For example Figure 8 As shown, the switch button 5 is located on the side of the housing 2 in the third direction Z, and the charging connector 8 is located at the end of the housing 2 away from the protective cover 1 in the first direction X; or, the switch button 5 can also be located on the side of the housing 2 in the second direction Y.

[0070] Furthermore, the head motor 6 is connected to the head assembly 4 via a reciprocating transmission assembly to form a reciprocating shaver. For example... Figure 2 and Figure 3 As shown, the reciprocating transmission assembly includes an eccentric wheel 62, a first drive element 63, a transmission element 64, a second drive element 65, and a third drive element 66. The first drive element 63 is connected to the output shaft of the cutter head motor 6 via the eccentric wheel 62, the second drive element 65 is connected to the first drive element 63 via the transmission element 64, and the third drive element 66 is fixedly connected to the first drive element 63. This transmission assembly has a compact structure and achieves the reciprocating motion of the cutter head through the transmission cooperation between a single cutter head motor 6 and the drive elements.

[0071] Specifically, during the transmission process, such as Figure 2 and Figure 3 As shown, the eccentric wheel 62 is fixed to the output shaft of the cutter head motor 6. The eccentric end of the eccentric wheel 62, which is eccentric relative to the output shaft, is inserted into the groove of the first drive unit 63. The groove extends along the second direction Y. Driven by the cutter head motor 6, the eccentric wheel 62 moves along a circular trajectory, pushing the groove to drive the first drive unit 63 to reciprocate along the third direction Z. The first drive unit 63 drives the second drive unit 65 to reciprocate along the third direction Z through the transmission unit 64, and also drives the third drive unit 66 to reciprocate along the third direction Z. The first drive unit 63, the second drive unit 65, and the third drive unit 66 respectively drive each cutter head to reciprocate along the third direction Z.

[0072] Specifically, regarding the arrangement of the drivers, such as Figure 3As shown, in the second direction Y, the third drive unit 66 is located between the first drive unit 63 and the second drive unit 65; the cutter head includes a blade cutter head 42 connected to the third drive unit 66 and two mesh cutter heads 43 respectively connected to each of the first drive unit 63 and the second drive unit 65.

[0073] Furthermore, in the structural design of the cutter head assembly 4, a reciprocating transmission assembly is incorporated, such as... Figure 2 and Figure 3 As shown, the cutter head assembly 4 specifically includes an outer blade holder 45, a cutter head seat 41, a mesh cutter head 43, and a blade cutter head 42.

[0074] Among them, such as Figure 2 , Figure 3 and Figure 5 As shown, the outer blade holder 45 is fixed to the opening of the housing 2 facing the protective cover 1, and is specifically detachably connected to the housing 2, for example, by snap-fit ​​connection or magnetic connection. The outer blade holder 45 has a cutting edge that extends through the first direction X, and the blade head seat 41 is fixed to the outer blade holder 45. The mesh blade head 43 and the slice blade head 42 are both provided on the blade head seat 41, and the mesh blade head 43 and the slice blade head 42 extend through the cutting edge of the outer blade holder 45. At this time, part of the blade head assembly 4 can be installed and removed from the housing 2 together with the outer blade holder 45.

[0075] Furthermore, in the structure of casing 2, such as Figure 2 As shown, it includes an outer shell 21, an inner shell 22, and an internal support 23.

[0076] The inner shell 22 and the internal support 23 are fixed within the outer shell 21. In the first direction X, the internal support 23 is fastened to the end of the inner shell 22 near the protective cover 1, specifically through a snap-fit ​​mechanism. The interior of the inner shell 22 forms the inner cavity of the housing 2; more specifically, the inner cavity is located between the internal support 23 and the inner shell 22. During assembly, the inner shell 22 and the internal support 23 can be sequentially assembled onto the outer shell 21. The fit between the inner shell 22 and the outer shell 21 ensures the structural strength of the housing 2.

[0077] Specifically, to improve the waterproof performance of the inner cavity of casing 2, such as Figure 2 and Figure 3 As shown, a waterproof ring 24 is also provided at the joint of the internal support 23 and the inner shell 22.

[0078] Specifically, to achieve the installation of the support plate 94 outside the casing 2, such as Figure 3As shown, the outer shell 21 has mounting holes 211 through its two side plates in the second direction Y, and the inner shell 22 has bottom grooves 221 on its two outer surfaces in the second direction Y. That is, the bottom grooves 221 are blind holes. Each bottom groove 221 corresponds to one end of each mounting hole 211 in the second direction Y, forming a mounting groove 212. Each mounting groove 212 contains a rotary bearing 91, and a support plate 94 is connected to the corresponding rotary bearing 91. Specifically, the outer ring of the rotary bearing 91 is fixed to the mounting groove 212, and the inner ring is fixedly connected to the support plate 94.

[0079] At this point, the mounting hole 211 provides sufficient space to install the rotary bearing 91, which connects the housing 2 and the support plate 94, ensuring smooth relative rotation between the support plate 94 and the housing 2. Alternatively, in other embodiments, blind-hole bearing mounting holes may be provided only on the housing 2.

[0080] Additionally, the casing 2 also includes a decorative ring 25. For example... Figure 3 , Figure 5 and Figure 6 As shown, the outer surface of the housing 21 in the second direction Y is also provided with a side groove communicating with the mounting hole 211 to provide machining space and facilitate the installation of the rotary bearing 91. Two decorative rings 25 respectively cover the two sides of the housing 21 in the second direction Y and correspondingly cover the side groove. Figure 3 As shown, a portion of the rotary bearing 91 can extend into the central through hole of the decorative ring 25 to connect to the support plate 94. The support plate 94 includes a plate body 92 and a central post 93. The plate body 92 covers the central through hole of the decorative ring 25, and the central post 93 is connected to the rotary bearing 91.

[0081] Specifically, to achieve the assembly of the housing 2 with the components in the inner cavity, such as... Figure 2 As shown, the internal support 23 is integrally equipped with a positioning frame, which extends into the inner shell 22 to install and position the cutter head motor 6 and the battery 7.

[0082] In addition, such as Figure 2 As shown, the internal support 23 is provided with a transmission hole 222. The cutter head assembly 4 and the cutter head motor 6 are located on both sides of the internal support 23 in the first direction X. The cutter head assembly 4 is connected to the cutter head motor 6 through the transmission hole 222 to realize the connection between the cutter head assembly 4 and the cutter head motor 6.

[0083] Specifically, such as Figure 2As shown, transmission hole 222 is the first transmission hole 223. The output shaft of the cutter head motor 6 passes through the first transmission hole 223, and a motor waterproof ring 61 is connected between the output shaft of the cutter head motor 6 and the first transmission hole 223. After the output shaft of the cutter head motor 6 passes through the first transmission hole 223, it is connected to the cutter head assembly 4 via a reciprocating transmission assembly. Furthermore, a transmission positioning groove is provided at the end of the internal bracket 23 facing the protective cover 1 to install the reciprocating transmission assembly.

[0084] Additionally, the reciprocating transmission assembly includes an eccentric wheel 62, a first drive element 63, a transmission element 64, and a second drive element 65. The first drive element 63 is connected to the output shaft of the cutter head motor 6 via the eccentric wheel 62. The second drive element 65 is connected to the first drive element 63 via the transmission element 64. Specifically, the transmission element 64 can be a rocker arm, whose center is rotatably connected to a central shaft fixedly mounted on the internal support 23. Its two ends are respectively connected to the drive slots of the first drive element 63 and the second drive element 65. Thus, when the first drive element 63 moves along one side of the Z-axis, it drives the rocker arm to swing around the central shaft. The rocker arm then drives the second drive element 65 to move towards the other side of the Z-axis. The structure is simple and easy to assemble. In other embodiments, a synchronous belt or similar structure can also be used to implement the transmission element 64.

[0085] Furthermore, to achieve the connection between the cutter head assembly 4 and the housing 2, such as... Figure 2 As shown, the internal support 23 is also provided with a hair storage chamber magnet 32 ​​on the side away from the inner shell 22 in the first direction X, specifically two magnets can be arranged sequentially in the third direction Z. The outer blade holder 45 is provided with an outer blade holder magnet 44 on the side facing the inner shell 22 in the first direction X. The outer blade holder 45 and the internal support 23 are arranged sequentially along the direction close to the inner shell 22, and the outer blade holder magnet 44 and the hair storage chamber magnet 32 ​​are magnetically connected along the first direction X for easy assembly and disassembly. At this time, other structures in the blade assembly 4 are located on the outer blade holder 45 for easy assembly and disassembly of the blade assembly 4. Each hair storage chamber magnet 32 ​​can magnetically attract one outer blade holder magnet 44.

[0086] In addition, such as Figure 2 As shown, the internal support 23, on the side away from the inner shell 22 in the first direction X, is also provided with a hair storage chamber rubber 31 and a hair storage chamber pressure plate 3. The hair storage chamber pressure plate 3 is sandwiched between the internal support 23 and the outer blade frame 45, and specifically, the hair storage chamber magnet 32 ​​can be sealed by the hair storage chamber pressure plate 3. The hair storage chamber rubber 31 is located between the hair storage chamber pressure plate 3 and the internal support 23 to ensure sealing. Of course, in other embodiments, such as Figure 8 As shown, the rubber chamber 31 and the pressure plate 3 of the firing chamber can also be omitted, and the outer blade frame 45 can be directly fastened to the inner support 23.

[0087] Furthermore, to achieve the connection of the protective cover 1, such as Figure 2As shown, a protective cover magnet 12 is provided on the side of the protective cover 1 facing the inner cavity of the housing 2. The protective cover magnet 12 is magnetically attracted to the cutter head, for example, magnetically attracted to the slicer head 42, which is convenient for installation and removal. Alternatively, the protective cover magnet 12 can also be magnetically attracted to the mesh cutter head 43 or the magnet 32 ​​of the spooling chamber, or the protective cover 1 can be detachably snapped onto the housing 2.

[0088] In addition, such as Figure 2 As shown, a counterweight 11 is provided on the side of the protective cover 1 facing the inner cavity of the housing 2 to improve the balance of the gravity distribution on the protective cover 1. In addition, a protective cover plate 13 is provided on the side of the protective cover 1 facing the inner cavity of the housing 2. The protective cover plate 13 is fixedly connected to the protective cover 1, and the protective cover plate 13 and the protective cover 1 can be positioned and connected to the counterweight 11 and the protective cover magnet 12.

[0089] In the second specific embodiment, such as Figures 7 to 12 As shown, unlike the above embodiments, the blade motor 6 is connected to the blade assembly 4 through a rotary transmission assembly to form a rotary shaver.

[0090] Specifically, such as Figure 8 As shown, on the internal support 23, the transmission hole 222 is the second transmission hole 224, which is set according to the number of cutter heads, for example, two are set. The rotary transmission assembly includes a motor gear 610, a transmission gear 68, and a transmission shaft 67. The motor gear 610, the transmission gear 68, and the cutter head motor 6 are located on the same side of the internal support 23 in the first direction X. The motor gear 610 is fixed to the output shaft of the cutter head motor 6 and is connected to the transmission gear 68. The transmission shaft 67 is fixed to the transmission gear 68 and passes through the second transmission hole 224 to connect to the cutter head in the cutter head assembly 4.

[0091] At this time, the cutter head motor 6 drives the motor gear 610 to rotate. The motor gear 610 meshes with the transmission gear 68 and drives each transmission gear 68 to rotate. The transmission gear 68 drives each transmission shaft 67 to rotate. Specifically, the transmission shaft 67 rotates on its own axis, thereby driving the cutter head connected to the transmission shaft 67 to rotate.

[0092] In addition, to achieve the fixation of the cutter head motor 6, such as Figure 8 As shown, a motor bracket 26 is also provided in the inner cavity of the housing 2, and the cutter head motor 6 is fixed to the motor bracket 26.

[0093] Furthermore, the motor bracket 26 can also be used to position the rotary transmission assembly. For example... Figure 8As shown, the motor gear 610 and transmission gear 68 in the rotary transmission assembly are located between the internal bracket 23 and the motor bracket 26, and the transmission shaft 67 is rotatably connected to the shaft groove of the motor bracket 26. The rotary transmission assembly also includes a cutter head shaft 69 for connecting the cutter head assembly 4. The cutter head shaft 69 is located on the side of the internal bracket 23 facing the protective cover 1 in the first direction X. Optionally, the cutter head shaft 69 is sleeved and fixed on the transmission shaft 67. In this case, the shaft groove of the motor bracket 26 and the cutter head shaft 69 can cooperate to position the transmission shaft 67.

[0094] In addition, the motor bracket 26 can also position the battery 7. For example... Figure 8 and Figure 10 As shown, only one battery 7, or a third battery 73, is installed inside the housing 2. The third battery 73 is electrically connected to the blade motor 6 and is fixed to the battery slot of the motor bracket 26. To ensure the shaver's center of gravity is centered, the motor bracket 26 includes a counterweight 261 located on the side of the blade motor 6 in the third direction Z, and the third battery 73 is located on the other side of the blade motor 6 in the third direction Z. The counterweight 261 is integrally formed on the motor bracket 26. In this way, the cooperation between the counterweight 261 and the third battery 73 reduces the gravitational imbalance on both sides of the blade motor 6 in the third direction Z.

[0095] Furthermore, to match rotary transmission components, such as Figure 8 and Figure 9 As shown, the cutter head assembly includes a cutter head, a cutter head bushing 412, a cutter head frame 46, a floating support 48, and an outer cutting edge frame 45.

[0096] The outer blade holder 45 is fixed to the opening of the housing 2 facing the protective cover 1, and is specifically fixedly connected to the internal support 23. The outer blade holder 45 is provided with a cutting edge that extends through in the first direction X, so that the blade head can extend out. The blade head bushing 412, the floating support 48, and the blade net bracket 411 are provided in the outer blade holder 45. The blade head bushing 412 is fitted on the blade head shaft 69. The floating support 48 is provided with a disassembly support block 49 at one end near the internal support 23. It is fixed to the internal support 23 by the disassembly support block 49. The floating support 48 is provided with a floating spring piece 410 at one end near the protective cover 1. The blade net bracket 411 is provided on the floating spring piece 410, which can realize the floating of the blade net bracket 411.

[0097] Each cutter head is connected to a cutter head sleeve 412 and rotates under the drive of the cutter head sleeve 412. Specifically, the cutter head is a rotating cutter head 47. A cutter head frame 46 is fitted onto the cutter head, and the cutter head frame 46 and the rotating cutter head 47 extend out through the cutting edge of the outer cutting edge frame 45. The cutter head rests on the cutter head frame 411, and the cutter head can be set to be circumferentially limited but axially movable relative to the cutter head shaft 69, so that it can float under the action of the cutter head frame 411 and the floating spring 410, specifically including floating in the first direction X.

[0098] Furthermore, regarding the arrangement of the switch button 5 and the charging connector 8, as follows: Figure 8 and Figure 9 As shown, on the third direction Z, a switch button 5 is provided on the side of the housing 2 near the counterweight frame 261. The switch button 5 is electrically connected to the third battery 73. A charging connector 8 is provided on the end of the housing 2 away from the protective cover 1 on the first direction X. The third battery 73 is electrically connected to the charging connector 8.

[0099] Additionally, on the third-party Z-axis, circuit board 51 is positioned between counterweight frame 261 and switch button 5, and circuit board 51 is electrically connected to switch button 5, third battery 73 and blade motor 6.

[0100] Obviously, the arrangement of the support member 9 is not limited to the manner provided in the above embodiments. For example, in some other specific embodiments, refer to... Figure 13 Only one support member 9 may be connected to the outer surface of the housing 2, specifically a second support member 96, which is a ring-shaped structure, such as a circular ring, and is sleeved on the outside of the housing 2, with the rotation center line of the second support member 96 parallel to the first direction X. Of course, in other embodiments, at least two second support members 96 may also be sequentially sleeved on the outside of the housing 2 along the first direction X.

[0101] It should be noted that in this type of embodiment with annular, sleeve-type support members, the outer surface of the housing 2 can be a cylindrical surface, or a portion thereof. Specifically, the second support member 96 includes a rotary bearing 91 and a support body 913. The support body 913 is an annular support sleeve 97. The cylindrical surface of the outer surface of the housing 2 is fixedly connected to the inner ring of the rotary bearing 91 in the second support member 96, while the support sleeve 97 is fitted around the outside of the rotary bearing 91 and fixedly connected to the outer ring of the rotary bearing 91.

[0102] In addition to the scheme where the support member 9 is directly connected to the outer surface of the frame 2 to achieve an external installation, based on the above embodiments, the rotating body may also include an external bracket 99 disposed outside the frame 2, which is used to connect the support member 9, further reducing direct damage to the housing 2. Furthermore, the external bracket 99 can be detachably connected to the outside of the housing 2 to facilitate the replacement and maintenance of the support member 9. In this case, the external bracket 99 can be detachably connected to the housing 2 using methods such as plugging, snap-fitting, or bolting. The support member 9 is connected to the external bracket 99, so it can be assembled onto the housing 2 together with the external bracket 99 or removed from the housing 2 together. Additionally, the housing 2 and the external bracket 99 can be connected by a fixed connection or a rotatable connection.

[0103] The external bracket 99 can be one or more, and each external bracket 99 can be provided with one or more support members 9. In addition, the shape of the external bracket 99 can be plate-shaped, for example, it is fixed to an outer surface of the housing 2; or it is annular, for example, it is sleeved on the outside of the housing 2; or it is a bent plate, such as a U-shaped plate or a C-shaped plate, whose concave side can fasten to the housing 2; or it is a bowl-shaped structure with a groove, whose groove can fasten to the outer side of the end of the housing 2 away from the protective cover.

[0104] Specifically, in the embodiment where the external support 99 is provided, with Figure 14 and Figure 15 In the illustrated embodiment, the support member 9 is a third support member 98 connected to the outer bracket 99. It includes a rotary bearing 91 and a support body 913. The support body 913 is a support block 910, which can be round, square, or other shapes. The inner ring of the rotary bearing 91 is fixed to the outer bracket 99, and the outer ring is fixed in the block mounting groove of the support block 910. The outer ring of the support block 910 engages with the rotary bearing 91.

[0105] In addition, two third support members 98 are located on two opposite surfaces of the housing 2 in the second direction Y, so that the user can pinch the two third support members 98 from both sides in the second direction Y for easy use.

[0106] Furthermore, to enable the third support member 98 to be assembled on both sides of the second direction Y, the external bracket 99 may include two external partition plates 911 connected to the housing 2 on both sides of the second direction Y, such as... Figure 14 and Figure 15 As shown, the external support 99 is a U-shaped frame, which includes an outer end plate 912 and two outer plates 911 fixed to both ends of the outer end plate 912. The outer end plate 912 is located at the end of the frame 2 away from the opening of the frame 2 in the first direction X. The two outer plates 911 are respectively fixedly connected to both sides of the housing 2 in the second direction Y. A through hole may also be provided in the middle of the outer end plate 912 to allow it to be fitted onto the outer side of a part of the structure at one end of the housing 2 in the first direction X, thereby improving the connection stability.

[0107] The connection between the external bracket 99 and the housing 2 can be either a fixed connection or a rotatable connection. For example... Figure 14 and Figure 15 As shown, the outer side of the housing 2 is provided with an outer support groove 27, and the outer partition plate 911 is inserted into the outer support groove 27; or, in Figure 16 and Figure 17 In the embodiment shown, an outer bracket mounting block 28 protrudes from the outer side of the housing 2, and an outer partition plate 911 is snapped into the outer bracket mounting block 28.

[0108] Furthermore, the dimensions of housing 2 in the second direction Y and the third direction Z can be the same. In this case, the cross-sectional shape of housing 2 perpendicular to the first direction X can be circular or angular, or the dimensions can be of different sizes, for example... Figure 1 or Figure 17 The flat shape in the middle.
