Technical Field

[0001] This application relates to the field of sports equipment technology, and in particular to housing devices, motor assemblies and fitness equipment. Background Technology

[0002] The housing device typically includes a handle and a housing assembly. The handle is rotatably supported on the housing assembly around a preset rotation axis. Users can pick up the housing device by holding the handle. In related technologies, the handle is often difficult to fix in a specific position, which causes inconvenience to users. Utility Model Content

[0003] This application provides a housing device, including a housing assembly, a sliding lock assembly, and a handle. The housing assembly has a ball groove. The sliding lock assembly includes a fixed sleeve, a sliding lock member, and a ball. The fixed sleeve is rotatably supported on the housing assembly about a preset rotation axis and has a receiving cavity. The sliding lock member is inserted into the receiving cavity along the rotation axis and can slide relative to the fixed sleeve. The sliding lock member includes a first sub-part and a second sub-part connected along the rotation axis. The radial dimension of the first sub-part is larger than the radial dimension of the second sub-part. The fixed sleeve has a ball hole that radially communicates the receiving cavity and the ball groove along the rotation axis, and the ball is at least partially located in the ball hole. The handle is assembled and cooperates with the fixed sleeve and rotates relative to the housing assembly with the fixed sleeve. When the sliding lock member slides to a first position along the rotation axis, the ball abuts against the first sub-part and is located in the ball groove and the ball hole, and the fixed sleeve is locked relative to the housing assembly. When the sliding lock member slides to a second position along the rotation axis, the ball abuts against the second sub-part and moves out of the ball groove, and the fixed sleeve can rotate relative to the housing assembly.

[0004] In some embodiments, the sliding lock is elastically supported on the fixed sleeve along the rotation axis and is at least partially exposed outside the fixed sleeve to receive external force. The sliding lock can slide to the second position along the rotation axis under the action of external force; after the external force disappears, the sliding lock automatically resets from the second position to the first position.

[0005] In some embodiments, the slide lock further includes a third sub-part, which includes a main body and a limiting member connected to each other. The main body is connected to the end of the second sub-part away from the first sub-part and is at least partially exposed outside the fixed sleeve to receive external force. The limiting member is used to limit the movement stroke of the slide lock along the rotation axis.

[0006] In some embodiments, the limiting member includes a first limiting portion located on the side of the main body facing the receiving cavity and on the periphery of the second sub-part; a first annular platform is provided on the inner wall of the receiving cavity, and when the sliding member slides to the second position, the first limiting portion abuts against the first annular platform.

[0007] In some embodiments, the slide lock assembly further includes an elastic element, which elastically supports the slide lock on the fixed sleeve; a second annular platform is also provided on the inner wall of the receiving cavity, which is spaced apart from the first annular platform along the rotation axis, and the elastic element elastically abuts against the second annular platform.

[0008] In some embodiments, the radial dimension of the main body is greater than the radial dimension of the second sub-part, there is a radial gap between the first limiting part and the second sub-part, the elastic member is sleeved on the periphery of the second sub-part and is at least partially located in the radial gap region, and the elastic member elastically abuts against the second annular platform and the main body.

[0009] In some embodiments, the limiting member further includes a second limiting part located on the side of the main body facing the receiving cavity. The second limiting part has a hook part. The first limiting part and the second limiting part are spaced apart in the circumferential direction of the second sub-part. A third annular platform is also provided on the inner wall of the receiving cavity. When the sliding lock member slides to the first position, the hook part is locked onto the third annular platform.

[0010] In some embodiments, the receiving cavity includes a first sub-cavity and a second sub-cavity connected sequentially along the rotation axis, the first sub-part is located in the first sub-cavity, at least a portion of the second sub-part is located in the second sub-cavity, and the radial dimension of the second sub-cavity on the side closer to the first sub-cavity is smaller than the maximum radial dimension of the first sub-part.

[0011] In some embodiments, the housing assembly includes an auxiliary component and a main housing for assembly and mating. A ball groove is provided on the auxiliary component, and a fixing sleeve is rotatably supported on the auxiliary component. The main housing is also provided with a mounting groove. In the retracted state, the handle is located in the mounting groove, and the outer contour of the handle smoothly transitions with the outer contour of the main housing.

[0012] In some embodiments, there are multiple ball grooves, which are distributed circumferentially around the fixed sleeve.

[0013] In some embodiments, the outer periphery of the fixing sleeve has a first plane, the handle is provided with a mounting cavity, the fixing sleeve is inserted into the mounting cavity along the rotation axis, the cavity wall of the mounting cavity has a second plane that mates with the first plane, and the first plane and the second plane are configured such that the handle remains relatively fixed relative to the fixing sleeve about the rotation axis.

[0014] Another aspect of this application provides a motor assembly, including a motor and the aforementioned housing device, wherein the motor is disposed within an accommodating cavity formed by the housing device.

[0015] This application also provides a fitness device including the aforementioned motor assembly.

[0016] In this application, the sliding of the sliding lock component and the cooperation between the ball bearing, the sliding lock component, the fixed sleeve, and the housing assembly can prevent relative rotation between the fixed sleeve and the housing assembly under specific conditions, thus locking the handle. Furthermore, moving the sliding lock component again releases the rotational restriction between the fixed sleeve and the housing assembly, allowing the handle to rotate freely. Therefore, moving the sliding lock component is sufficient to lock and unlock the handle, making operation simple and convenient. In addition, the sliding lock component can lock the handle in a specific position, thereby reducing the risk of unexpected wobbling, abnormal noise, or collision with the housing assembly and other components.

Detailed Implementation

[0019] The technical solutions of 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 the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] The terms "first" and "second" used in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This application describes a fitness device 10, which can provide resistance or power to a cable 4, allowing a user to exercise by reciprocatingly pulling the cable 4 or being driven by the cable 4. Figure 1 and Figure 2 As shown, the fitness equipment 10 may include a power supply component 1, a cable rewinding component 2, and a motor component 3. The power supply component 1 provides power to the entire fitness equipment 10, the cable rewinding component 2 rewinds the cable 4, and the motor component 3 provides power or resistance to the cable rewinding component 2.

[0023] The structure of the motor assembly 3 provided in this application will be described in detail below.

[0024] like Figure 2 and Figure 3 As shown, the motor assembly 3 includes a motor 31 ( Figure 2The component marked 31 (i.e., the output shaft of the motor 31) and the housing device 30 are included. The motor 31 is disposed within the accommodating cavity 3221 formed by the housing device 30 and can be used to provide power or resistance to the take-up and unwind assembly 2. Figure 2 This shows the state in which the motor 31 is housed within the receiving cavity 3221. Figure 3 The image shows the state where the motor 31 is not housed in the accommodating cavity 3221. The space occupied by the motor 31 is the accommodating cavity 3221.

[0025] The structure of the housing device 30 provided in this application will now be described in detail.

[0026] like Figure 4 and Figure 5 As shown, the housing device 30 includes a housing assembly 32, a sliding lock assembly 33, and a handle 34. The motor 31 can be disposed in the receiving cavity 3221 formed by the housing assembly 32. The sliding lock assembly 33 is rotatably supported on the housing assembly 32. The handle 34 is assembled and cooperated with the sliding lock assembly 33 and rotates with the sliding lock assembly 33 relative to the housing assembly 32.

[0027] For example, such as Figure 4 As shown, the handle 34 can rotate relative to the housing assembly 32 with the sliding lock assembly 33 until it fits against the outer wall surface of the housing assembly 32, so that the handle 34 is in a retracted state. Figure 5 As shown, the handle 34 can also rotate with the sliding lock assembly 33 relative to the housing assembly 32 to a position away from the housing assembly 32, so that the user can grip and lift the housing device 30, i.e., the handle 34 is in use.

[0028] like Figure 5 and Figure 6 As shown, the housing assembly 32 may also be provided with a mounting groove 3222, which can be a recess formed by the housing assembly 32 towards the receiving cavity 3221. In the retracted state, the handle 34 is located within the mounting groove 3222. Figure 4 This shows the state in which the handle 34 is received within the mounting slot 3222. Figure 5 The image shows the state where the handle 34 is not accommodated in the mounting slot 3222. The space occupied by the handle 34 is the mounting slot 3222.

[0029] In some embodiments, the outer contour of the handle 34 can smoothly transition with the outer contour of the housing assembly 32. This configuration allows the handle 34 to be completely housed within the housing assembly 32 without occupying additional external space of the housing device 30, thus saving storage space. Furthermore, the smooth transition between the outer contour of the handle 34 and the outer contour of the housing assembly 32 enhances the visual appeal of the housing device 30.

[0030] "The outer contour of the handle 34 and the outer contour of the housing assembly 32 are smoothly connected" can mean that the outer contour of the handle 34 and the outer contour of the housing assembly 32 have the same tangential direction at the junction, and the distance between the outer contour of the handle 34 and the outer contour of the housing assembly 32 is less than 1 mm in the normal direction perpendicular to the tangential direction.

[0031] The term "perpendicular" as used in this application refers to approximately perpendicularity. An angle between two objects between 75° and 105° can be considered as perpendicularity.

[0032] like Figure 6 As shown, the housing assembly 32 is provided with a ball groove 320. (See also...) Figure 6 and Figure 7 The sliding lock assembly 33 includes a fixed sleeve 331, a sliding lock element 332, and a ball bearing 333. The fixed sleeve 331 is rotatably supported on the housing assembly 32 about a predetermined rotation axis M1. The fixed sleeve 331 has a receiving cavity 3310, and the sliding lock element 332 is inserted into the receiving cavity 3310 along the rotation axis M1 and can slide relative to the fixed sleeve 331. The sliding lock element 332 includes a first sub-part 3321 and a second sub-part 3322 connected along the rotation axis M1, with the radial dimension of the first sub-part 3321 being larger than that of the second sub-part 3322. The fixed sleeve 331 has a ball hole 3311 radially communicating with the receiving cavity 3310 and the ball groove 320 along the rotation axis M1, and the ball bearing 333 is at least partially located within the ball hole 3311.

[0033] The handle 34 is assembled with the fixed sleeve 331 and rotates relative to the housing assembly 32 as the fixed sleeve 331 rotates. Specifically, one end of the fixed sleeve 331 with a ball bearing hole 3311 can be rotatably connected to the housing assembly 32, and the other end of the fixed sleeve 331 along the rotation axis M1 can be assembled with the handle 34, so that the handle 34 and the fixed sleeve 331 can rotate synchronously relative to the housing assembly 32.

[0034] In some embodiments, the handle 34 can be assembled and fitted with the fixing sleeve 331 by means of adhesive bonding, snap-fitting, screwing, etc.

[0035] like Figure 6 As shown, the housing assembly 32 includes an auxiliary component 321 and a main housing 322 for assembly and mating. A ball groove 320 can be provided on the auxiliary component 321, and a fixing sleeve 331 is rotatably supported on the auxiliary component 321. Specifically, the auxiliary component 321 is provided with a through hole 3210, and the fixing sleeve 331 can be inserted into the through hole 3210 along the rotation axis M1, so that the fixing sleeve 331 and the auxiliary component 321 can rotate relative to each other.

[0036] As mentioned above, the handle 34 can rotate synchronously with the fixed sleeve 331 relative to the housing assembly 32, that is, the handle 34 and the fixed sleeve 331 remain relatively fixed. By assembling and cooperating with the auxiliary component 321 with the main housing 322, and by rotatably connecting the fixed sleeve 331 and the auxiliary component 321, the sliding lock assembly 33, the handle 34 and the auxiliary component 321 can be removed from the main housing 322 as a whole, making it convenient for the user to replace the handle 34.

[0037] like Figure 6 As shown, the accommodating cavity 3221 can be formed by the main housing 322, and the mounting groove 3222 is provided on the main housing 322. The outer contour of the handle 34 can smoothly transition with the outer contour of the main housing 322.

[0038] In some embodiments, such as Figure 7 As shown, the outer periphery of the fixing sleeve 331 has a first plane 3315. (As indicated...) Figure 8 As shown, the handle 34 is provided with a mounting cavity 340, and the fixing sleeve 331 can be inserted into the mounting cavity 340 along the rotation axis M1. The cavity wall of the mounting cavity 340 has a second plane 341 that mates with the first plane 3315. The first plane 3315 and the second plane 341 are configured such that the handle 34 remains relatively fixed relative to the fixing sleeve 331 about the rotation axis M1. Figure 4 This shows the state in which the retaining sleeve 331 is accommodated within the mounting cavity 340. Figure 8 The image shows the state in which the mounting cavity 340 is not occupied by the fixing sleeve 331. The space occupied by the fixing sleeve 331 on the handle 34 is the mounting cavity 340.

[0039] When the fixed sleeve 331 is inserted into the mounting cavity 340 of the handle 34, the first plane 3315 on the fixed sleeve 331 and the second plane 341 on the handle 34 abut against each other. Since the two planes form a geometric constraint, they can withstand circumferential shear force, thereby effectively preventing the handle 34 and the fixed sleeve 331 from rotating relative to each other around the rotation axis M1, thus achieving anti-rotation positioning.

[0040] like Figure 9 and Figure 10 As shown, when the sliding lock 332 slides to the first position along the rotation axis M1, the ball 333 abuts against the first sub-part 3321 and is located within the ball groove 320 and ball hole 3311, locking the fixed sleeve 331 relative to the housing assembly 32. In this case, the handle 34 is locked together with the fixed sleeve 331 and cannot rotate relative to the housing assembly 32. Figure 11 and Figure 12As shown, when the sliding lock 332 slides to the second position along the rotation axis M1, the ball 333 abuts against the second sub-part 3322 and moves out of the ball groove 320, and is located in the receiving cavity 3310 and the ball hole 3311, so that the fixed sleeve 331 can rotate relative to the housing assembly 32, and the handle 34 can rotate freely relative to the housing assembly 32.

[0041] For example, when in use, the user can operate the sliding lock 332 to move it to the second position along the rotation axis M1, causing the ball 333 to move out of the ball groove 320 and into the ball hole 3311 and the receiving cavity 3310. This allows the fixed sleeve 331 and the housing assembly 32 to rotate completely relative to each other. Correspondingly, the handle 34 can also rotate freely, i.e., the handle 34 is in the unlocked state. The user can rotate the handle 34 to put it in the storage state or the use state. After the handle 34 is rotated to the desired state, the user can operate the sliding lock 332 again to move it to the first position along the rotation axis M1, causing the ball 333 to be pushed out by the first sub-part 3321 and partially into the ball groove 320. In this situation, the fixed sleeve 331 and the housing assembly 32 are restricted by the ball 333, and the first sub-part 3321 prevents the ball 333 from moving into the receiving cavity 3310, so that the fixed sleeve 331 and the housing assembly 32 cannot rotate relative to each other. Accordingly, the handle 34 cannot rotate either, that is, the handle 34 is in a locked state, so that the position of the handle 34 can be fixed.

[0042] In this embodiment, by utilizing the sliding of the sliding lock 332 and the cooperation between the ball bearing 333 and the sliding lock 332, the fixed sleeve 331, and the housing assembly 32, relative rotation between the fixed sleeve 331 and the housing assembly 32 can be prevented under specific conditions, thus locking the handle 34. Furthermore, after moving the sliding lock 332 again, the rotation restriction between the fixed sleeve 331 and the housing assembly 32 can be released, allowing the handle 34 to rotate freely. Therefore, moving the sliding lock 332 is sufficient to lock and unlock the handle 34, making the operation simple and convenient. In addition, the sliding lock 332 can lock the handle 34 in a specific position, thereby reducing the risk of the handle 34 unexpectedly swinging, producing abnormal noise, or colliding with the housing assembly 32 or other components.

[0043] In some embodiments, the sliding lock 332 can be elastically supported on the fixed sleeve 331 along the rotation axis M1 and at least partially exposed outside the fixed sleeve 331 to receive external forces. The sliding lock 332 can slide to a second position along the rotation axis M1 under the action of external forces. After the external forces disappear, the sliding lock 332 automatically returns to the first position from the second position.

[0044] For example, the sliding lock 332 itself can be elastic and elastically supported on the fixed sleeve 331. After the external force disappears, the sliding lock 332 can automatically return to the first position based on elastic deformation. Of course, the sliding lock 332 can also be elastically supported on the fixed sleeve 331 by other elastic components.

[0045] For example, during use, the user can press the exposed portion of the sliding lock 332 to slide it to the second position, thereby causing the ball 333 to move out of the ball groove 320 and abut against the second sub-part 3322. The fixing sleeve 331 is then unlocked from the housing assembly 32, for example, the fixing sleeve 331 is unlocked from the auxiliary part 321, allowing the user to rotate the handle 34 to any position. After use, releasing the sliding lock 332 allows it to automatically return to the first position under the action of elasticity. The first sub-part 3321 of the sliding lock 332 can push the ball 333 out to at least partially lie within the ball groove 320. The fixing sleeve 331 remains relatively fixed to the housing assembly 32, thereby locking the handle 34.

[0046] In some embodiments, if the sliding lock 332 is released when the handle 34 is not rotated to the point where the ball groove 320 communicates with the ball hole 3311, the first sub-part 3321 will not push the ball 333 out into the ball groove 320. In this case, the reset of the sliding lock 332 is restricted by the ball 333 and cannot move to the first position, thereby prompting the user to adjust the position of the handle 34.

[0047] like Figure 7 and Figure 10 As shown, the sliding lock 332 also includes a third sub-part 3323, which includes a main body 33231 and a limiting member 33232 connected to it. The main body 33231 is connected to the end of the second sub-part 3322 opposite to the first sub-part 3321 and is at least partially exposed outside the fixed sleeve 331 to receive external forces. The limiting member 33232 is used to limit the travel of the sliding lock 332 along the rotation axis M1.

[0048] In some embodiments, the main body 33231 and the limiting member 33232 can be integrally formed. For example, the main body 33231 and the limiting member 33232 can be integrally formed by injection molding. By forming the main body 33231 and the limiting member 33232 into an integral structure, the number of parts in the housing device 30 can be reduced, which is beneficial to improving assembly efficiency. Of course, the main body 33231 and the limiting member 33232 can also be assembled together.

[0049] In some embodiments, the third sub-part 3323 can be assembled and connected to the second sub-part 3322, and the second sub-part 3322 can be integrally formed with the first sub-part 3321. For example, the third sub-part 3323 can be assembled and connected to the second sub-part 3322 by welding, snap-fitting, bonding, or other methods. During assembly, the opposite ends of the third sub-part 3323 and the second sub-part 3322 along the rotation axis M1 can be inserted into the receiving cavity 3310 to achieve assembly, thereby simplifying the processing of the slide lock assembly 33. At the same time, when other components (e.g., the elastic element 334 mentioned below) are fitted on the second sub-part 3322, it is beneficial to reduce the assembly difficulty. This application does not limit the connection method of each part of the slide lock assembly 332, and those skilled in the art can choose according to actual needs.

[0050] like Figure 10 and Figure 12 As shown, in some embodiments, the limiting member 33232 includes a first limiting portion 332321, which is located on the side of the main body 33231 facing the receiving cavity 3310 and on the periphery of the second sub-part 3322. A first annular platform 3312 is provided on the inner wall of the receiving cavity 3310. When the sliding member 332 slides to the second position, the first limiting portion 332321 abuts against the first annular platform 3312. The first limiting portion 332321 can be used to limit the maximum travel of the sliding member 332 along the rotation axis M1 during unlocking, thereby reducing the risk of the sliding member 332 disengaging from the fixed sleeve 331 due to excessive external force.

[0051] like Figure 10 and Figure 12 As shown, the slide lock assembly 33 also includes an elastic element 334, and the slide lock member 332 is elastically supported on the fixed sleeve 331 by the elastic element 334. In some embodiments, the elastic element 334 may be a spring, a sheet spring, a coil spring, etc., and of course, other elastically deformable materials well known to those skilled in the art may also be used. This embodiment uses a spring as an example to illustrate the use of the elastic element 334.

[0052] Compared to the sliding lock 332 which has its own deformation capability, by setting the sliding lock 332 to be elastically supported by the elastic element 334 on the fixed sleeve 331, it is beneficial to improve the service life of the sliding lock 332. Even after multiple uses, the sliding lock 332 will not fail.

[0053] like Figure 10 and Figure 12As shown, a second annular platform 3313 is also provided on the inner wall of the receiving cavity 3310. The second annular platform 3313 and the first annular platform 3312 are spaced apart along the rotation axis M1. The elastic element 334 elastically abuts against the second annular platform 3313. The second annular platform 3313 serves two purposes. First, it can limit the maximum travel of the elastic element 334 along the rotation axis M1 during the unlocking process, thereby reducing the risk of the elastic element 334 disengaging from the fixed sleeve 331 due to excessive external force. Second, during the sliding of the sliding lock 332, the preload between the elastic element 334 and the second annular platform 3313 continuously increases, and the elastic potential energy of the elastic element 334 continuously accumulates. This accumulation of potential energy provides a stronger driving force for the reset of the sliding lock 332, thereby reducing the reset resistance and ensuring that the sliding lock 332 can be smoothly and reliably reset to the first position.

[0054] like Figure 10 and Figure 12 As shown, the radial dimension of the main body 33231 is larger than the radial dimension of the second sub-part 3322. There is a radial gap between the first limiting part 332321 and the second sub-part 3322. The elastic member 334 is sleeved on the periphery of the second sub-part 3322 and is at least partially located in the radial gap area. The elastic member 334 elastically abuts against the second annular platform 3313 and the main body 33231.

[0055] The radial dimension of the main body 33231 is larger than that of the second sub-body 3322. During the resetting process of the sliding lock 332, the main body 33231 can be used to limit the maximum travel of the elastic member 334 along the rotation axis M1, thereby reducing the risk of the elastic member 334 disengaging from the fixed sleeve 331. At the same time, by abutting the two ends of the elastic member 334 against the second annular platform 3313 and the main body 33231 respectively, the risk of the elastic member 334 displacing along the rotation axis M1 and wobbling, causing abnormal noise, can be reduced.

[0056] like Figure 10 and Figure 12As shown, the limiting member 33232 also includes a second limiting part 332322, which is located on the side of the main body 33231 facing the receiving cavity 3310 and has a hook part 332320. The first limiting part 332321 and the second limiting part 332322 are spaced apart in the circumferential direction of the second sub-part 3322. A third annular platform 3314 is also provided on the inner wall of the receiving cavity 3310. When the sliding member 332 slides to the first position, the hook part 332320 is engaged with the third annular platform 3314. During the process of the elastic member 334 driving the sliding member 332 to return to the first position, the third annular platform 3314 can be used to limit the maximum stroke of the sliding member 332 along the rotation axis M1, thereby reducing the risk of the sliding member 332 disengaging from the fixed sleeve 331 due to excessive elastic potential energy.

[0057] like Figure 12 As shown, the receiving cavity 3310 includes a first sub-cavity 33101 and a second sub-cavity 33102 connected sequentially along the rotation axis M1. A first sub-part 3321 is located in the first sub-cavity 33101, and at least a portion of the second sub-part 3322 is located in the second sub-cavity 33102. The radial dimension of the second sub-cavity 33102 near the first sub-cavity 33101 can be smaller than the maximum radial dimension of the first sub-part 3321. With this configuration, during the process of the elastic member 334 driving the sliding lock member 332 to reset to the first position, the cavity wall of the second sub-cavity 33102 can limit the maximum travel of the sliding lock member 332 along the rotation axis M1, thereby further reducing the risk of the sliding lock member 332 disengaging from the fixed sleeve 331 due to excessive elastic potential energy.

[0058] In some embodiments, such as Figure 13 As shown, there can be multiple ball grooves 320, which are distributed circumferentially around the fixed sleeve 331. In this way, when the ball 333 moves into different ball grooves 320, the fixed sleeve 331 can remain relatively fixed to the housing assembly 32 in multiple different positions, so that the handle 34 can be locked in multiple different positions to meet different user needs.

[0059] In summary, by setting the handle 34 and the sliding lock assembly 33 to be relatively fixed, the handle 34 can rotate relative to the housing assembly 32 via the sliding lock assembly 33. The handle 34 is relatively fixed to the fixed sleeve 331. The movable sliding lock 332 can drive the ball 333 to move. The ball 333 can restrict the relative movement between the fixed sleeve 331 and the housing assembly 32, keeping them relatively fixed and the handle 34 in a locked state. Alternatively, the fixed sleeve 331 can be rotated relative to the housing assembly 32, thereby putting the handle 34 in an unlocked state. Thus, locking and unlocking the handle 34 can be achieved in a relatively simple way, improving user portability.
