[0017] In some embodiments, the transmission member is a rigid component and is capable of moving vertically within the second stirring rod. At least one of the driving part and the locking tongue is provided with a wedge surface at the point of contact with each other. The wedge surface is used to convert the vertical movement of the driving part into the lateral movement of the locking tongue.

[0018] In some embodiments, there are multiple locking devices, and the locking tongues of the multiple locking devices are arranged circumferentially along the drive unit.

[0050] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0051] In the description of the embodiments of this application, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0052] This application provides a stirring device; please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 6 The stirring device 100 includes a stirring wheel 1, a stirring rod assembly 2, and a locking device 3 (see reference). Figure 5 ).

[0053] The stirring rod assembly 2 includes a first stirring rod 21 and a second stirring rod 22. Both the first stirring rod 21 and the second stirring rod 22 are arranged along the height direction.

[0054] The bottom end of the first stirring rod 21 is connected to the stirring wheel 1. The stirring wheel 1 drives the first stirring rod 21 to rotate synchronously.

[0055] The second stirring rod 22 is disposed on the first stirring rod 21.

[0056] The locking device 3 is used to connect the first stirring rod 21 and the second stirring rod 22. The locking device 3 can selectively lock the second stirring rod 22 at at least two different height positions, so that the stirring rod assembly 2 has at least two different working lengths.

[0057] The working length of the stirring rod assembly 2 refers to the overall length of the stirring rod assembly 2 in the height direction.

[0058] The height position of the second stirring rod 22 refers to the relative position of a reference point on the second stirring rod 22 with respect to another selected reference point on the first stirring rod 21 in the height direction. The reference point can be selected at any position on the second stirring rod 22, and similarly, another reference point can be selected at any position on the first stirring rod 21.

[0059] For example, please see Figure 1 , Figure 3 , Figure 4 When the second stirring rod 22 is locked at the first height position, the working length of the stirring rod assembly 2 is the first length. (See also...) Figure 2 , Figure 5 , Figure 6 When the second stirring rod 22 is locked at the second height position, the working length of the stirring rod assembly 2 is the second length, and the first length is less than the second length. In other words, the working length of the stirring rod assembly 2 is adjustable.

[0060] In this embodiment, when the second stirring rod 22 is in the unlocked state, the second stirring rod 22 can move relative to the first stirring rod 21. After the user pulls the second stirring rod 22 upward or presses it downward to a suitable height position, the locking device 3 locks the second stirring rod 22, thus locking the second stirring rod 22 at the current height position.

[0061] This application provides a washing device; please refer to the following embodiments. Figure 10 , Figure 11 and Figure 12 The device includes a washing drum 200 and an agitator 100 according to any embodiment of the present application, wherein the agitator 100 is rotatably disposed within the washing drum 200. For example, the agitator 1 is located approximately at the bottom of the washing drum 200, and the agitator assembly 2 extends into the upper space of the washing drum 200.

[0062] The type of washing equipment is not limited; it can be a washing machine, shoe washing machine, fruit and vegetable washing machine, dishwasher, steam mop, etc.

[0063] In this embodiment of the application, a washing machine is used as an example for description.

[0064] In this embodiment of the stirring device 100, when washing a large number of small garments, such as long-sleeved or long-legged garments, the locking device 2 can lock the second stirring rod 22 to a higher height position (e.g., when washing a large number of small garments). Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 (As shown in the height position), the agitator assembly 2 can reduce clothes tangling and improve the washing ratio, and the agitator assembly 2 will not significantly affect the loading and unloading of small items of clothing; when washing large items of clothing, such as thick winter coats, down jackets, sheets, duvet covers, etc., the locking device 2 can lock the second agitator 22 to a lower height position (e.g., at the height position shown). Figure 1 , Figure 3 , Figure 4 (As shown in the figure), it increases the washing machine's capacity ratio and makes it easy to load and unload clothes.

[0065] It should be noted that for the same stirring device, the longer the working length of the stirring rod assembly 2, the higher the top of the stirring rod assembly is inside the washing drum, and the better the anti-tangling effect on the clothes above.

[0066] The stirring device 100 of this application embodiment can change the working length of the stirring rod assembly 2 according to the type of washing items, which can both improve the tangling of clothes and facilitate the handling of washing items.

[0067] In the stirring device 100 of this application embodiment, since the locking device 3 locks the second stirring rod 22 onto the first stirring rod 21, the working length of the stirring rod assembly is fixed and will not change arbitrarily, regardless of whether the stirring wheel 1 rotates forward or backward.

[0068] In the embodiments of this application, forward and reverse rotation are only used to illustrate that the rotation directions are opposite and do not specifically refer to any particular direction.

[0069] For example, please refer to Figure 10 and Figure 12 The washing equipment also includes an outer tub 300, with a washing drum 200 housed within it. The washing drum can hold water on its own, meaning it is a non-perforated inner tub. Alternatively, the washing drum can hold water through the outer tub 300. No restrictions are placed on this.

[0070] The connection between the bottom end of the first stirring rod 21 and the stirring wheel 1 is not limited, for example, including but not limited to detachable connections such as screws and bolts, or non-detachable connections such as fusion, welding, riveting, and integral injection molding.

[0071] Specifically, in some embodiments, please refer to Figures 1 to 5 The stirring device 100 shown has a first stirring rod 21 and a stirring wheel 1 as separate components, which are fixedly connected together.

[0072] In other embodiments, please refer to Figures 6 to 9 The stirring device 100 shown has a first stirring rod 21 and stirring wheel 1 as an integral structure, for example, integral injection molding.

[0073] The upper surface of the agitator wheel 1 is provided with multiple water-spraying ridges 11. During the rotation of the agitator wheel 1, the water-spraying ridges 11 agitate the water flow and wash the items.

[0074] The specific structure of the water-digging ridge 11 is not limited.

[0075] In some embodiments, please refer to Figure 1 and Figure 2 The radial outer end of the water-dipping ridge 11 is bent roughly toward one side of the circumference.

[0076] In other embodiments, please refer to Figure 7The water-digging ridge 11 extends roughly in a straight radial direction.

[0077] The cross-sectional shape of the first stirring rod 21 in a plane perpendicular to the height direction is not limited; for example, it can be elliptical, polygonal, circular, etc.

[0078] The cross-sectional shape of the second stirring rod 22 in a plane perpendicular to the height direction is not limited; for example, it can be elliptical, polygonal, circular, etc.

[0079] The specific assembly relationship between the first stirring rod 21 and the second stirring rod 22 is not limited. For example, the second stirring rod 22 may be disposed on one side of the first stirring rod 21 in a transverse direction. Here, transverse refers to any direction in a plane perpendicular to the height direction.

[0080] For example, the first stirring rod 21 and the second stirring rod 22 are nested together. In this embodiment, the nesting arrangement can increase the lateral stiffness of the second stirring rod 22 and improve the structural reliability of the stirring rod assembly 2.

[0081] For example, the second stirring rod 22 can be nested inside the first stirring rod 21, or the first stirring rod 21 can be nested inside the second stirring rod 22.

[0082] One of the first stirring rod 21 and the second stirring rod 22 has a guide groove extending along the height direction on its circumferential surface, and the other has a guide rib 2211 extending along the height direction on its circumferential surface (see reference). Figure 6 The guide rib 2211 slides with the guide groove along the height direction.

[0083] During the process of lifting or pressing down the second stirring rod 22, the cooperation between the guide rib 2211 and the guide groove can effectively guide the movement of the second stirring rod 22. In addition, the guide rib 2211 and the guide groove are in a circumferential anti-rotation fit, that is, the second stirring rod 22 and the first stirring rod 21 will not rotate relative to each other, but can only move relative to each other along the height direction. This facilitates the first stirring rod 21 to transmit torque to the second stirring rod 22, so that the locking device 3 basically does not bear or bears less tangential shear force, thus improving the stress conditions of the locking device 3.

[0084] In an embodiment where the first stirring rod 21 is nested inside the second stirring rod 22, the outer circumferential surface of the first stirring rod 21 may be provided with guide ribs 2211, and the inner circumferential surface of the second stirring rod 22 may be provided with guide grooves; or, the outer circumferential surface of the first stirring rod 21 may be provided with guide grooves, and the inner circumferential surface of the second stirring rod 22 may be provided with guide ribs 2211.

[0085] In an embodiment where the second stirring rod 22 is nested inside the first stirring rod 21, the inner circumferential surface of the first stirring rod 21 may be provided with guide ribs 2211, and the outer circumferential surface of the second stirring rod 22 may be provided with guide grooves; or, the inner circumferential surface of the first stirring rod 21 may be provided with guide grooves, and the outer circumferential surface of the second stirring rod 22 may be provided with guide ribs 2211.

[0086] For example, please refer to Figure 9 The upper end of the first stirring rod 21 is provided with a first limiting part 211, and the lower end of the second stirring rod 22 is provided with a second limiting part 225. The first limiting part 211 is always located above the second limiting part 225. When the second stirring rod 22 moves upward to its limit position, the first limiting part 211 and the second limiting part 225 come into contact with each other. The limit position refers to the highest position that the design allows the second stirring rod 22 to move upward when it is in the unlocked state.

[0087] In this embodiment, the stop cooperation between the first limiting part 211 and the second limiting part 225 can prevent the second stirring rod 22 from coming off the top of the first stirring rod 21.

[0088] In an embodiment where the first stirring rod 21 is nested inside the second stirring rod 22, at least a portion of the first limiting portion 211 protrudes from the outer circumferential surface of the first stirring rod 21, and at least a portion of the second limiting portion 225 protrudes from the inner circumferential surface of the second stirring rod 22. For example, the first limiting portion 211 is formed as a rib protruding from the outer circumferential surface of the first stirring rod 21, and the second limiting portion 225 may be a positioning pin inserted into the second stirring rod 22 from the outside in.

[0089] In an embodiment where the second stirring rod 22 is nested inside the first stirring rod 21, at least a portion of the first limiting portion 211 protrudes from the inner circumferential surface of the first stirring rod 21, and at least a portion of the second limiting portion 225 protrudes from the outer circumferential surface of the second stirring rod 22. For example, the first limiting portion 211 is formed as a rib protruding from the outer circumferential surface of the second stirring rod 22, and the second limiting portion 225 may be a positioning pin inserted into the first stirring rod 21 from the outside in.

[0090] The specific locking method of the locking device 3 is not limited.

[0091] For example, in the first stirring rod 21 and the second stirring rod 22, the side wall of the one located on the radially outer side is provided with multi-stage locking grooves 21a arranged at intervals along the height direction. The locking device 3 is provided on the one located on the radially inner side.

[0092] It should be noted that the locking groove 21a can be a through groove or a blind groove.

[0093] It should be noted that the height of the locking grooves 21a of the same level is the same, and the number of locking grooves of the same level can be one or more.

[0094] In an embodiment where the first stirring rod 21 is nested inside the second stirring rod 22, the second stirring rod 22 is located radially outward, and the first stirring rod 21 is located radially inward. Each locking groove 21a is disposed on the second stirring rod 22, and the locking device 3 is disposed on the first stirring rod 21. Each locking groove 21a can be a through groove penetrating the sidewall of the second stirring rod 22, or a blind groove not penetrating the sidewall of the second stirring rod 22.

[0095] In an embodiment where the second stirring rod 22 is nested inside the first stirring rod 21, the first stirring rod 21 is located radially outward, and the second stirring rod 22 is located radially inward. Each locking groove 21a is disposed on the first stirring rod 21, and the locking device 3 is disposed on the second stirring rod 22. Each locking groove 21a can be a through groove penetrating the sidewall of the first stirring rod 21, or a blind groove not penetrating the sidewall of the first stirring rod 21.

[0096] For example, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 The locking device 3 includes a locking tongue 32 and an elastic element 31 for driving the locking tongue 32 to reset. The locking tongue 32 can be inserted into or removed from the locking groove 21a. When the locking tongue 32 is inserted into the locking groove 21a, the locking device 3 locks the second stirring rod 22 at its current height position, and the second stirring rod 22 is in a locked state. When the locking device is removed from the locking groove 21a, the second stirring rod 22 is in an unlocked state and can move at least up and down.

[0097] In some embodiments, for example, the elastic element 31 is configured as a spring sheet, and the locking device 3 is disposed within the radial gap between the first stirring rod 21 and the second stirring rod 22. The first end of the spring sheet is connected to the first stirring rod 21 or the second stirring rod 22 on the radially inner side, and the locking tongue 32 is disposed at the second end of the spring sheet. The second end of the spring sheet is a free end.

[0098] In this embodiment, when unlocking is required, the locking tongue 32 is pressed radially inward, causing the locking tongue 32 to exit the locking groove 21a. The second stirring rod 22 is moved vertically. When the second stirring rod 22 moves to the point where the locking tongue 32 is aligned with the next level locking groove 21a, the locking tongue 32 is automatically inserted into the locking groove 21a under the elastic force of the spring piece, and the locking device 3 switches from the release position to the locking position.

[0099] For example, the stirring device 100 includes an unlocking mechanism, see [link to relevant documentation]. Figure 4 , Figure 5 , Figure 8 and Figure 9The unlocking mechanism includes a transmission component and a reset component 42, which is used to drive the transmission component to reset to the initial position.

[0100] The transmission component is used to move under the action of external force and cause the locking tongue 32 to exit the locking groove 21a. That is, under the action of external force, the transmission component is driven to move, and the movement of the transmission component can cause the locking tongue 32 to exit the locking groove 21a, thereby causing the locking device 3 to switch from the locked position to the released position.

[0101] In this embodiment, the unlocking mechanism allows the user to easily unlock the second stirring rod 22 without the need for special tools such as screwdrivers, and the unlocking operation is convenient. The transmission component can be constructed to facilitate the user's application of force, and the part for the user to apply force can also be placed in an ergonomic position to improve the user experience.

[0102] It should be noted that the initial position of the transmission component refers to its position when no force is applied by the user; this is the default position of the transmission component. When the transmission component is in the initial position, the locking tongue 32 is in the locked position, that is, the locking tongue 32 is inserted into the locking groove 21a, and the second stirring rod 22 is in the locked state.

[0103] The unlocking mechanism and the locking device 3 are located on the same component, for example, both on the first stirring rod 21, or both on the second stirring rod 22.

[0104] For example, the second stirring rod 22 is nested inside the first stirring rod 21, the unlocking mechanism and the locking device 3 are both disposed inside the second stirring rod 22, and the operating part 411 is disposed at the top of the second stirring rod 22. In this way, it is convenient for the user to apply force to the operating part 411 without the user having to bend over excessively.

[0105] For example, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 The transmission component includes an operating part 411 for receiving external driving force, a driving part 412 for driving cooperation with the locking tongue 32, and a power transmission member 413 connecting the operating part 411 and the driving part 412. The driving part 412 and the operating part 411 transmit force through the power transmission member 413.

[0106] The operating part 411 is located at the upper end of the second stirring rod 22. Specifically, the operating part 411 will never extend into the first stirring rod 21 and will never be blocked by the first stirring rod 21, so as to avoid the first stirring rod 21 affecting the user's application of force to the operating part 411.

[0107] The power transmission component 413 is arranged generally in the vertical direction, the operating part 411 is located at the upper end of the power transmission component 413, and the driving part 412 is located at the lower end of the power transmission component 413.

[0108] The operating unit 411 can move in the vertical direction under the action of external force, and the driving unit 412 is used to drive the locking tongue 32 to move laterally. Here, "lateral" refers to any direction in a plane perpendicular to the vertical direction, such as the radial direction along the rotation trajectory of the stirring rod assembly.

[0109] In this embodiment, during the up-down movement of the operating part 411, the power transmission member 413 moves synchronously, and the power transmission member 413 drives the driving part 412 to move synchronously. During the movement, the driving part 412 enables the locking tongue 32 to move radially inward, thereby exiting the locking groove 21a.

[0110] Because the second stirring rod 22 has a large space in the vertical direction, the operating part 411 can have a large movement stroke and installation space in the vertical direction, thus improving the user experience.

[0111] The position where the reset member 42 applies the restoring force to the transmission member is not limited, as long as it can reset the transmission member. For example, the reset member 42 can act on the operating part 411, the lower power transmission member 413, or the drive part 412.

[0112] It should be noted that the power transmission component 413 can be a rigid component or a flexible component such as a rope.

[0113] In this embodiment of the application, a rigid component refers to a component whose shape and size remain basically unchanged during movement and after being subjected to force.

[0114] For example, the transmission component is a rigid member, that is, the power transmission component 413 is also a rigid member, and the power transmission component 413, the operating part 411, and the driving part 412 are connected together to form a rigid whole. In this way, the placement of the reset component 42 has a high degree of design flexibility. The reset component 42 can apply force to any one of the power transmission component 413, the operating part 411, or the driving part 412 to drive the entire transmission component to move in the desired direction.

[0115] For example, the transmission component, as a rigid member, can move vertically within the second stirring rod 22. In this embodiment, when the stirring device 100 rotates forward or backward, the transmission component is subjected to a transverse shear force, which is perpendicular to the direction of movement of the transmission component. Therefore, the shear force hardly forces the transmission component to move, thus reducing the probability of the locking function of the locking device 3 failing due to rotation.

[0116] For example, the transmission member moves upward under the action of an external force and can move downward to the initial position under the action of the reset member 42. In this embodiment, the transmission member's own weight is downward, and the force exerted by the reset member 42 on the transmission member has at least a downward component. Therefore, the drive unit 412 can be reliably held in the expected position, thereby enabling the drive unit 412 to reliably hold the locking tongue 32 in the locked position.

[0117] Please see Figure 5 and Figure 8 At least one of the drive unit 412 and the locking tongue 32 is provided with a wedge surface 412a and 32a at the part where they contact each other. The wedge surface 412a and 32a are used to convert the up-and-down movement of the drive unit 412 into the radial movement of the locking tongue 32.

[0118] When the latch 32 is in the locked position, the side of the drive unit 412 abuts against the radially inner end of the latch 32, and the radially outer end of the latch 32 passes through the locking groove 21a. Since the drive unit 412 prevents the latch 32 from moving radially inward, it holds the latch 32 in its current locked state. In this state, the elastic member 31 applies a radially inward force to the latch 32.

[0119] When the drive unit 412 moves upward and avoids the locking tongue 32, the locking tongue 32 moves radially inward under the action of the elastic member 31 and exits the locking groove 21a. In this way, the locking tongue 32 can be switched from the locked position to the unlocked position.

[0120] For example, please refer to Figure 5 and Figure 8 The drive unit 412 has a downwardly inclined wedge surface 412a on its periphery, which is used to abut against the radial inner end of the locking tongue 32.

[0121] For example, please refer to Figure 5 and Figure 8 The inner radial end of the locking tongue 32 is provided with an upwardly inclined wedge surface 32a, which is used to contact the drive unit 412.

[0122] It is understandable that in embodiments where both the drive unit 412 and the locking tongue 32 are provided with wedge surfaces, the two wedge surfaces are in contact with each other.

[0123] The number of locking devices 3 can be one. Alternatively, there can be multiple locking devices 3, with the locking tongues 32 of the multiple locking devices 3 arranged circumferentially along the drive unit 412, for example, evenly. In this embodiment, the multiple locking tongues 32 exert a relatively uniform force on the drive unit 412, reducing the lateral force on the drive unit 412 and reducing the probability of lateral swaying of the transmission component. Here, "multiple" refers to at least two.

[0124] For example, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 The second stirring rod 22 includes a hollow rod body 221. A power transmission component 413 passes through the rod body 221. The rod body 221 serves as the main structure of the second stirring rod 22.

[0125] For example, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 The second stirring rod 22 includes a mounting base 222 disposed at the lower end of the rod body 221. The mounting base 222 and the rod body 221 are separate structures, that is, they are not integrally formed structures.

[0126] The locking device 3 is mounted on the mounting base 222, which is connected to the lower end of the rod 221.

[0127] During assembly, the locking device 3 can be installed on the mounting base 222 first, and then the mounting base 222 can be connected to the bottom end of the rod body 221. In this way, the locking tongue 32 device can be hidden inside the second stirring rod 22.

[0128] The specific structure of the mounting base 222 is not limited. For example, in some embodiments, the mounting base 222 is provided with a radially extending groove, and the locking tongue 32 passes through the groove, which plays a good guiding role for the locking tongue 32.

[0129] For example, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 The second stirring rod 22 includes a guide sleeve 224 disposed within the rod body 221. The guide sleeve 224 has a guide through hole 224a extending in the vertical direction. A transmission component slidably passes through the guide through hole 224a; for example, a power transmission component 413 passes through the guide through hole 224a. The guide through hole 224a guides the vertical movement of the power transmission component 413. In addition, the guide sleeve 224 increases the lateral stiffness of the transmission component, reducing the probability of lateral bending of the power transmission component 413.

[0130] During the assembly process, the guide sleeve 224 can be inserted into the rod body 221 from the bottom end and fixed first, and then the mounting base 222 can be inserted into the rod body 221 and fixed.

[0131] Understandably, the guide hole 224a can be relatively long in the vertical direction to further enhance the lateral stiffness of the power transmission component 413.

[0132] The specific structure of the guide sleeve 224 is not limited, as long as it is easy to assemble inside the rod body 221.

[0133] In some embodiments, please refer to Figure 8 and Figure 9 The guide sleeve 224 includes a core 2241 and a frame 2242. The periphery of the frame 2242 contacts the inner wall of the rod 221. The core 2241 is located at the center of the frame 2242. The guide through hole 224a penetrates the core 2241 in the vertical direction. In this embodiment, the guide through hole 224a has a relatively long length in the vertical direction.

[0134] In other embodiments, please refer to Figure 4 and Figure 5 In this embodiment, the guide sleeve 224 includes a core 2241, but does not include the aforementioned frame 2242. In this embodiment, the guide through hole 224a has a smaller length in the vertical direction.

[0135] For example, please refer to Figures 1 to 9 The second stirring rod 22 includes an end cap 223 disposed at the top of the rod body 221, the lower end of the end cap 223 being embedded in the opening at the top of the rod body 221.

[0136] The connection method between the end cap 223 and the rod body 221 is not limited. For example, the side wall of the rod body 221 is provided with a slot, and the lower end of the end cap 223 is provided with an elastic buckle. The elastic buckle is hooked into the slot, so that the end cap 223 and the rod body 221 can be quickly and detachably connected.

[0137] For example, please refer to Figure 1 , Figure 2 ,and Figure 6 The end cap 223 includes a cap body 2231 and a handle 2232 disposed on the top side of the cap body 2231. The handle 2232 is for the user to hold, so that the user can apply force to the second stirring rod 22, for example, by pulling the second stirring rod 22 upward or pressing the second stirring rod 22 downward.

[0138] The specific shape of the handle 2232 is not limited, as long as it is easy for the user to hold.

[0139] For example, the bottom surface of the handle 2232 is spaced apart from the top surface of the cover 2231, and an opening is provided on the bottom side of the handle 2232, from which a portion of the operating part 411 extends.

[0140] When the user grips the handle 2232, their fingers can press against the operating part 411 from the bottom. By gripping tightly, the user can apply an upward force to the operating part 411, which in turn drives the transmission component to move upward. In this embodiment, the position of the operating part 411 is ergonomic, making it convenient for the user to apply force with one hand.

[0141] For example, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 The reset member 42 is disposed inside the handle 2232 and applies a downward force to the operating part 411. In this embodiment, the reset member 42 acts directly on the operating part 411, which can ensure the operating feel of the operating part 411, reduce the probability of the operating part 411 shaking, and improve the user experience.

[0142] For example, please refer to Figure 2 and Figure 6 The end cap 223 is formed by two separate half-shells 223' and 223″ joined together in the horizontal direction. A part of the structure of the handle 2232 and a part of the structure of the cover 2231 constitute one half-shell 223', and another part of the structure of the handle 2232 and another part of the structure of the cover 2231 constitute the other half-shell 223″.

[0143] For example, the two half-shells 223' and 223″ are each injection molded.

[0144] During assembly, the operating part 411 and the reset part 42 are placed at the mating positions of the two half-shells 223' and 223″, and then connected together after the two half-shells 223' and 223″ are mated.

[0145] The specific construction of handle 2232 is not limited.

[0146] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 6 Both ends of the handle 2232 along its length are connected to the cover 2231, which can improve the structural strength of the handle 2232.

[0147] For example, please refer to Figure 3 , Figure 4 , Figure 8 and Figure 9 The power transmission component 413 includes a frame portion 4132 and a rod portion 4131 that are separately arranged. The frame portion 4132 is disposed inside the end cap 223 and located at the joint of the two half shells 223' and 223″. The rod portion 4131 passes through the rod body 221. The driving part 412 is disposed at the bottom end of the rod portion 4131. The top end of the rod portion 4131 is connected to the frame portion 4132.

[0148] When an external force presses the operating part 411 upward, the frame part 4132 moves upward as a whole, which in turn drives the rod part 4131 and the drive part to move upward.

[0149] In this embodiment, a portion of the frame 4132 can be arranged inside the handle to facilitate power transmission.

[0150] For example, the lower part of the frame portion 4132 is arranged along the inner wall of the cover 2231, the upper part of the frame portion 4132 extends into the space inside the handle 2232 from both ends of the handle 2232, and the operating part 411 is provided at the bottom of the portion of the frame portion 4132 located inside the handle 2232.

[0151] For example, the top end of the rod 4131 is provided with a thread, and the frame 4132 is provided with a threaded hole, and the threaded portion at the top end of the rod 4131 is screwed into the threaded hole.

[0152] The rod 4131 extends generally in a vertical direction, and the drive part 412 is disposed at the bottom end of the rod 4131.

[0153] For example, the rod 4131 and the drive part 412 are an integral structure.
