Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and more specifically, to a milk shaker. Background Technology

[0002] A milk shaker is a small, electrically powered device used for rapidly mixing or stirring liquids, primarily for preparing milk powder, protein powder, beverages, or other powdered substances with liquids. It thoroughly mixes the powdered substance with water or other liquids by rapidly shaking or rotating it, preventing clumping and ensuring a uniform mixture. However, existing milk shakers can only achieve braking by cutting off the control circuit of the drive motor. This braking function is relatively simple; if the control circuit of the drive motor cannot be cut off, braking is impossible, leading to inconvenience and significant safety hazards.

[0003] In conclusion, how to effectively solve the problems of inconvenience and safety hazards in the current use of breast pumps is an urgent issue that needs to be addressed by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a breast shaker that can effectively solve the problems of inconvenience in using current breast shakers and the existence of safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A breast pump includes:

[0007] case;

[0008] The milk-shaking device is installed in the shell and can move relative to the shell in a preset manner. The milk-shaking device is provided with a restraint device for restraining the object being shaken.

[0009] The limiting component has at least one locking part;

[0010] A stop device is provided, wherein one of the limiting member and the stop device is installed in the housing and the other is installed in the milk shaking device. The stop device includes a stop member that cooperates with the limiting member and a power member for controlling the stop member to enter and exit the stop state. When the stop member enters the stop state, it can prevent the milk shaking device from performing a preset type of activity by abutting against the locking part.

[0011] In the aforementioned milk shaker, when shaking is required, the bottle to be shaken is placed on the shaking device so that the restraint device restrains the bottle. At this time, the stop part retracts from the stop state, and the power unit for shaking drives the shaking device to move in a preset manner, so that the shaking device can shake the milk. During the shaking process, if the milk shaker malfunctions, such as when the power unit driving the shaking device cannot stop driving, the power unit can be activated to control the stop part to enter the stop state. The stop part abuts against the locking part to prevent the shaking device from continuing to move in the preset manner, thereby braking the shaking device, and then the bottle can be removed. In the aforementioned milk shaker, a stop device and a limiting part are added so that when shaking stops, the power unit of the stop device can control the stop part to enter the stop state to prevent relative movement with the limiting part in the abutment direction, thereby stopping the shaking device from moving in the preset manner, thus stopping the shaking. This allows the shaken object to be removed when the power unit driving the shaking device cannot stop driving, making the milk shaker safer and more convenient to use. In conclusion, this breast shaker effectively solves the problems of inconvenience and safety hazards associated with current breast shakers.

[0013] In some technical solutions, the stopping device is a telescopic drive device, so that the power member can drive the stopping member to extend to a first position and retract to a second position; when the stopping member extends to the first position, the stopping member can abut against the locking part in a preset direction of movement to enter the stopping state; when the stopping member retracts to the second position, the stopping member disengages from the locking part to disengage from the stopping state.

[0014] In some technical solutions, the power component is an electromagnet.

[0015] In some technical solutions, when the electromagnet is energized, it can drive the stop to retract to the second position, and when the electromagnet is de-energized, it can drive the stop to extend to the first position under the action of the elastic device; or when the electromagnet is energized, it can drive the stop to extend to the first position, and when the electromagnet is de-energized, it can drive the stop to retract to the second position under the action of the elastic device.

[0019] In some technical solutions, the drive mechanism includes at least one lead screw, which is rotatably mounted on the base.

[0038] In some embodiments, a milk shaker is provided, mainly including a housing 12, a limiting member 14, and a stop device 15. It is generally also provided with a drive device to drive the milk shaker 100 to shake milk.

[0039] The milk-shaking device 100 is disposed on the housing 12. The milk-shaking device 100 can move relative to the housing 12 in a preset manner. The milk-shaking device 100 is provided with a constraint device for constraining the object being shaken, so that when the milk-shaking device 100 moves in the preset manner, the constraint device can drive the object being shaken to shake, thereby realizing milk shaking. The specific preset manner of the milk-shaking device 100 is not limited, as long as it can complete the milk shaking. Of course, the milk-shaking device 100 can only perform the preset manner of movement, or it can further perform other forms of movement.

[0040] The specific preset activity can be selected as needed. It can be continuous rotation, oscillation within a preset angle range, or left-right swaying. Left-right swaying can be either left-right rotation or left-right translation, as long as it can achieve the desired milk-shaking effect, ensuring that the milk powder and water in the bottle are mixed evenly. The restraint device can be a fixing device, such as a clamping device, to ensure that the object being shaken and the milk-shaking device move synchronously. Alternatively, the restraint device can be a closed container, in which the object being shaken is placed, so that when the closed container oscillates left and right, it pushes the object being shaken to sway left and right within the closed container, similar to the shaking of clothes in a washing machine drum.

[0041] One of the limiting member 14 and the stopping device 15 is installed in the housing 12, and the other is installed in the milk shaking device 100. When the stopping device 15 enters the stopping state and limits the limiting member 14, it prevents the milk shaking device 100 from moving relative to the housing 12 in a preset manner. If the preset manner of movement is rotation, it can prevent the milk shaking device 100 from rotating relative to the housing 12, but it can also prevent or not prevent the milk shaking device 100 from moving relative to the housing 12 along the rotation axis. That is, it can prevent or not prevent movements other than the preset manner.

[0042] One of the limiting member 14 and the stopping device 15 is installed in the housing 12, and the other is installed in the milk shaking device 100. At least two installation examples are possible: one example is that the limiting member 14 is directly or indirectly fixedly installed in the housing 12, while the power member 15-2 of the stopping device 15 is directly or indirectly fixedly installed in the milk shaking device 100; another example is, as shown in the figure, the power member 15-2 of the stopping device 15 is directly or indirectly fixedly installed in the housing 12, while the limiting member 14 is directly or indirectly fixedly installed in the milk shaking device 100.

[0043] The stop device 15 enters a stop state to limit the limit member 14, as shown in the following example. At least one locking portion 14-1 is provided on the limit member 14, and the stop device 15 includes a stop member 15-1 and a power member 15-2. The stop member 15-1 cooperates with the limit member 14, and the power member 15-2 controls the stop member 15-1 to enter and exit the stop state. When the stop member 15-1 enters the stop state, it can prevent the milk shaking device 100 from performing a preset type of movement by abutting against the abutting portion, thereby braking the milk shaking device 100. The stop member 15-1 can enter and exit the stopped state in at least two ways: one is by changing the position of the stop member 15-1, as shown in the attached figure, through translation; the other is by changing the constraint state of the stop member 15-1, such as changing the degree of freedom of movement in at least one direction. For example, during meshing transmission, when the stop gear meshes with the limit gear, the limit gear cannot rotate when the stop gear is prevented from rotating, thus entering the stopped state. When the stop gear can rotate freely, the limit gear can rotate freely to exit the stopped state. By abutting against the locking part 14-1, the stop member 15-1 provides a limit, ensuring effective braking of the milk shaking device 100.

[0044] In the aforementioned milk shaker, when milk shaking is required, the bottle to be shaken is placed at the milk shaker 100 so that the restraint device restrains the bottle. At this time, the stop 15-1 exits the stop state, and the power unit for shaking will drive the milk shaker 100 to move in a preset manner so that the milk shaker 100 can shake the milk. During the shaking process, if the milk shaker malfunctions, such as when the power unit driving the milk shaker 100 cannot stop driving, the power unit 15-2 can be activated to control the stop 15-1 to enter the stop state. The stop 15-1 abuts against the locking part 14-1 to prevent the milk shaker 100 from continuing to move in the preset manner, thereby braking the milk shaker 100, and then the bottle can be removed. In the aforementioned milk shaker, a stop device 15 and a limiting member 14 are added. This allows the stop device 15-1 to enter a stopped state via the power component 15-2 of the stop device 15 when shaking stops, preventing relative movement with the limiting member 14 in the contact direction. This prevents the milk shaker 100 from moving in a preset manner, thus stopping the shaking. Furthermore, if the power component driving the milk shaker 100 cannot stop driving, the shaken object can be removed, making the milk shaker safer and more convenient to use. In summary, this milk shaker effectively solves the problems of inconvenience and safety hazards associated with current milk shakers.

[0045] In some embodiments, as described above, the power element 15-2 can be a moving drive device to drive the stop element 15-1 to move in and out of the stopped state; and / or the power element 15-2 can be a locking device to limit whether the stop element 15-1 can move in and out of the stopped state. That is, when multiple stop devices 15 are provided, the power element 15-2 of some stop devices 15 can be a moving drive device, and the power element 15-2 of some stop devices 15 can be a locking device.

[0046] As a moving drive device, such as the telescopic drive device described later, it can also be a rotating drive device, so that the corresponding stop 15-1 can enter and exit the stop state. Taking the rotating drive device as an example, one end of the stop 15-1 is connected to the drive shaft of the rotating drive device, and the other end is used for the locking part 14-1 to abut. The locking device can be a magnetic attraction device or a locking device. The locking device can be a stepper motor, and the stop 15-1 can be a stop gear, while the limiting member 14 is a limiting gear. When the stepper motor is energized, it is restricted from rotating, so the stop gear cannot rotate, thereby preventing the limiting gear from rotating, so that the positions of the two remain relatively fixed, thereby preventing the milk shaking device 100 from rotating (one of the preset forms of movement), that is, achieving braking.

[0047] In some embodiments, taking a mobile drive device as an example, the stop 15-1 can be a telescopic member, and the power member 15-2 can be a telescopic drive device, so that the power member 15-2 can drive the stop 15-1 to extend from the second position to the first position or retract from the first position to the second position. When the stop 15-1 extends to the first position, the stop 15-1 can abut against the locking part 14-1 in a predetermined direction of movement to enter a stopped state, thereby braking the milk shaking device 100. When the stop 15-1 retracts to the second position, the stop 15-1 can move perpendicular to the abutment direction to disengage from the locking part 14-1, thereby disengaging from the stopped state.

[0048] In some embodiments, the telescopic drive device, i.e., the power component 15-2, can be an electric cylinder, a telescopic pneumatic cylinder, or a combination of a motor and a crank-slider mechanism. For ease of operation, the power component 15-2 is preferably an electromagnet, while the stop component 15-1 is an iron core or a part of an iron core, or it can be a structure fixedly installed on the iron core. Specifically, it should be able to drive the stop component 15-1 to move between a first position and a second position.

[0049] In some embodiments, when the electromagnet is energized, it can cause the stop 15-1 to retract to the second position, and when the electromagnet is de-energized, the stop 15-1 can extend to the first position under the action of the elastic device; or when the electromagnet is energized, it can cause the stop 15-1 to extend to the first position, and when the electromagnet is de-energized, the stop 15-1 can retract to the second position under the action of the elastic device. Alternatively, the direction of the current can be changed to allow the braking member to move back and forth between the first and second positions.

[0050] In some embodiments, for ease of arrangement, the limiting member 14 can be a toothed disc or a rack, and the corresponding locking part 14-1 can be a tooth, so as to uniformly form a plurality of locking parts 14-1, so that when in use, the stop member 15-1 of the stop device 15 can be engaged with any locking part 14-1 to achieve rapid braking.

[0051] In some embodiments, specifically as described above, the preset form can be rotated around a preset axis. In this case, the limiting member 14 can have at least two of the following embodiments: one embodiment is, as shown in the figure, the limiting member 14 can be a toothed disc fixed on the milk shaking device 100, with the teeth arranged radially outward, and the stop device 15 is directly or indirectly fixedly installed on the housing 12; another embodiment is, the limiting member 14 can be a toothed ring fixed relative to the housing 12, with the teeth arranged radially inward, and the stop device 15 is fixedly installed on the milk shaking device 100.

[0052] In some embodiments, to facilitate milk shaking, the milk shaking device 100 may include a receiving container 4; in this case, the restraining device is a clamping device, generally an elastic clamping device. The limiting member 14 may be a toothed ring integrated into the outer side of the bottom of the receiving container 4, with the teeth facing radially outward.

[0053] In some embodiments, weight-reducing holes may be provided in the teeth to avoid excessive weight.

[0054] In some embodiments, the milk shaking device 100 includes a base 1. The restraint device, as a clamping device, includes a movable seat 2, a drive mechanism, and an elastic structure 3.

[0055] As shown in the attached figure, the milk shaking device 100 may include a base 1 and may further include a container 4.

[0056] The movable seat 2 serves as the driven object of the drive mechanism, which drives the movable seat 22 to move relative to the base 11 in a preset direction, thereby causing the elastic structure 3 to deform elastically. The mode of movement is not limited; it can be rotation or linear movement, as shown in the attached diagram, primarily linear movement. The preset direction, for example, when the movable seat 2 moves relative to the base 1 in a preset direction, causes the elastic structure 3 to deform elastically in the clamping direction or in the releasing direction, thus clamping or releasing the target object. The driving form of the drive mechanism is also not limited and can be set according to the mode of movement. For example, rotation can be achieved by directly using a motor 6, while linear movement can be achieved by using a hydraulic telescopic device or an electric cylinder. An electric cylinder refers to a combination structure of a motor 6 and a lead screw and nut transmission mechanism. The drive mechanism that drives the movable seat 2 to move in the preset direction can be combined with the drive mechanism that drives the milk-shaking device 100 to move in a preset manner, both powered by the same power source, or they can be completely different drive mechanisms.

[0057] The elastic structure 3 is connected to the base 1 and the movable seat 2 at both ends, so that when the movable seat 2 moves in a preset direction relative to the base 1, it can drive the elastic structure 3 to undergo elastic deformation, so as to clamp or release the target object. In fact, there are at least two specific embodiments.

[0058] In some embodiments, when the movable seat 2 moves in a preset direction relative to the base 1, it can cause the elastic structure 3 to undergo elastic deformation to clamp the target object; when the driving mechanism stops driving the movable seat 2 and there is no restriction, the elastic structure 3 will deform in the opposite direction under the action of elastic deformation force, that is, it will deform in the direction of releasing the target object. At this time, the movable seat 2 can move in the opposite direction of the preset direction.

[0059] In some other embodiments, when the movable seat 2 moves relative to the base 1 in a preset direction, it can cause the elastic structure 3 to undergo elastic deformation to release the target object; when the driving mechanism stops driving the movable seat 22, and there is no restriction, the elastic deformation force of the elastic structure 3 will cause it to deform in the opposite direction, that is, to deform in the direction of clamping the target object. At this time, the movable seat 2 can move in the opposite direction of the preset direction.

[0060] In some embodiments, when the movable seat 2 moves relative to the base 1 in a preset direction, it can cause the elastic structure 3 to undergo elastic deformation to clamp the target object. When the drive mechanism stops driving the movable seat 2, the elastic structure 3 can remain in elastic deformation to maintain elastic clamping of the target object. When the movable seat 2 moves in the opposite direction relative to the base 1 in the preset direction, it can cause the elastic structure 3 to recover its elastic deformation in the direction of elastic deformation recovery to release the target object. That is, at this time, the clamping or releasing of the target object by the elastic structure 3 is achieved by the drive mechanism.

[0061] When the elastic structure 3 deforms, it clamps or releases the target object. The main mechanisms are as follows: due to elastic deformation, at least a portion of the elastic structure 3 moves along the clamping direction, reducing the clamping space and thus clamping the target object to restrict its position; at least a portion of the elastic structure 3 moves along the releasing direction, increasing the clamping space, allowing the target object to move freely without restriction. As shown in the attached diagram, clamping is achieved when the protruding portion of the elastic structure 3 moves towards the receiving cavity, and releasing is achieved when it moves away from the receiving cavity. The protruding portion of the elastic structure 3 is the structural part used to contact the target object.

[0062] The form of the elastic structure 3 is not specifically required, but it is such that, under elastic deformation, at least the local structure, especially the structure of the target that needs to be contacted, can move along the clamping direction or along the releasing direction.

[0063] In the above embodiments, the target object is released or clamped by the elastic structure 3 and the driving mechanism. Because the elastic structure 3 is deformed by the driving mechanism, the clamping effect of the elastic structure 33 can be well controlled, and the deformation state of the elastic structure 3 can be easily and actively changed, allowing the clamping device to be in both a clamped and released state. Furthermore, in the clamped state, due to the elastic clamping of the elastic structure 33, it has better adaptability to the target object, accommodating a wider range of sizes and making the clamping operation convenient. In summary, the above-described milk shaker effectively solves the problem of inconvenient target object clamping operation in milk shakers.

[0064] In some embodiments, a limiting member 14 may be provided on the edge of the base 1, such as forming a toothed ring on the edge of the base 1 as a limiting member 14, and the teeth of the toothed ring as a locking part 14-1.

[0065] In some embodiments, for ease of driving, the drive mechanism may include at least one lead screw 7. The lead screw 7 is rotatably mounted on the base 1 about its own axis and is restricted by the base 1 to move relative to the base 1 along its axial direction, so that the lead screw 7 can only rotate relative to the base 1 about its own axis. The movable seat 2 is provided with a threaded hole 8 that threadedly engages with the lead screw 7. The threaded hole 8 and the lead screw 7 together form a lead screw nut transmission mechanism. The movable seat 2 is restricted to following the rotation of the lead screw 7, and can only move relative to the base 1 along the axial direction of the lead screw 7. The restriction of the movable seat 2 to follow the rotation of the lead screw 7 can be achieved by multiple parallel lead screws 7 and threaded holes 8 engaging with each other to prevent the movable seat 2 from rotating with the lead screw 7.

[0066] Through the transmission of the aforementioned lead screw and nut transmission mechanism, the movable seat 2 can be moved along the axial direction of the lead screw 7 when the lead screw 7 rotates, that is, the movable seat 2 can move relative to the base 1 in a preset direction. The preset direction is one of the axial directions of the lead screw 7. As shown in the attached figure, the base 1 and the movable seat 2 are arranged side-by-side along the axial direction of the lead screw 7. When the base 1 and the movable seat 2 are arranged side-by-side along the preset direction, the preset direction can be: either the direction in which the movable seat 2 moves closer to the base 1, at which point the elastic structure 3 undergoes elastic deformation when its two ends move closer to each other; or the direction in which the movable seat 2 moves away from the base 1, at which point the elastic structure 3 undergoes elastic deformation when its two ends move away from each other.

[0067] It should be noted that the rotation of the lead screw 7 can be directly or indirectly driven by the motor 6 or other rotation drive mechanisms. As shown in the attached figure, the drive mechanism includes the motor 6.

[0068] In some embodiments, for the convenience of transmission, a set of transmission gears 10 is generally provided between the rotary drive mechanism (motor 6 as described below) and the lead screw 7. Specifically, the set of transmission gears 10 may include a meshing central gear 9 and a transmission gear 10, so that the rotary drive mechanism drives the central gear 9 to rotate, and then the central gear 9 drives the transmission gear 10 to rotate, and the rotation of the transmission gear 10 drives the lead screw 7 to rotate.

[0069] As mentioned above, one or more lead screws 7 can be provided. When one lead screw 7 is provided, for the convenience of transmission, one lead screw 7 can be used in conjunction with multiple guide rods to surround the target object, such as surrounding the receiving container 4 formed on the base 1, where the receiving container 4 is used to hold the baby bottle. When multiple lead screws 7 are provided, for the convenience of transmission, multiple lead screws 7 can be used to surround the target object, such as surrounding the receiving container 4.

[0070] For example, the movable seat 2 can be an annular seat fitted on the outside of the receiving barrel 4. Along the circumferential direction, one or more lead screws 7 can be arranged. As shown in the attached figure, two lead screws 7 can be arranged, and they are located on the lateral sides of the receiving barrel 4 respectively.

[0071] In some embodiments, for ease of transmission, each lead screw 7 can be fixed to a transmission gear 10 at its end. Each transmission gear 10 is arranged around the central gear 9 and meshes with the central gear 9. This allows the central gear 9 to rotate, driving each transmission gear 10 to rotate, thus causing all lead screws 7 to rotate synchronously and synchronously drive the movable seat 2 to move up and down. As shown in the attached figures, when two lead screws 7 are provided, located on opposite sides of the central gear 9 in the radial direction, correspondingly, transmission gears 10 are provided on opposite sides of the central gear 9 in the radial direction. The transmission gears 10 are fixedly connected to the corresponding lead screws 7 and are coaxially arranged.

[0072] For ease of arrangement, the central gear 9 can be placed at the bottom of the receiving barrel 4, or the base 1 can be placed on the side away from the receiving cavity.

[0073] To facilitate the rotation of the central gear 9 and avoid excessive space occupation in the vertical direction, the motor 6 and the container 4 can be arranged side by side in the horizontal direction. The motor 6 drives the central gear 9 to rotate through the belt transmission mechanism 11. The rotation of the central gear 9 can drive the transmission gear 10 to rotate, so that the lead screw 7 rotates. The rotation of the lead screw 7 drives the movable seat 2 to move in a preset direction, so that the elastic structure 3 can be elastically deformed to clamp or release the target object.

[0074] In some embodiments, the base 1 can be rotatably mounted directly or indirectly to the housing 12, so that the rotation of the base 1 drives the rotation of the bottle on it to achieve milk shaking, i.e., the rotation is a preset form of activity. It should be noted that: the base 1 can be rotatably mounted directly to the housing 12, such as by direct rotational engagement so that the base 1 can rotate relative to the housing 12; the base 1 can be rotatably mounted indirectly to the housing 12, and a base 13 fixed relative to the housing 12 can be further provided, and the base 1 can be rotatably mounted on the base 13, thereby achieving the indirect rotatable mounting of the base 1 to the housing 12.

[0075] The rotation axis of the central gear 9 is aligned with the rotation axis of the base 1. When torque is applied to the central gear 9, it can first drive the transmission gear 10 to rotate. When the elastic structure 33 clamps the target object, the transmission gear 10 cannot rotate further relative to the base 1, thus restricting the rotation of the central gear 9 relative to the base 1. At this time, the torque of the central gear 9 can be transmitted to the base 1 to drive it to rotate, thereby realizing milk shaking. That is, the meshing of the motor 6, the central gear 9, and the transmission gear 10 drives the milk shaking device 100 to shake the milk. The drive mechanism that drives the movable seat 2 to move in a preset direction can be combined with the drive device that drives the milk shaking device 100 to move in a preset form, all achieved by the same motor 6. Specifically, the central gear 9 and the transmission gear 10 can be directly or indirectly rotatably connected to the base 1. Of course, to ensure that the motor 6 drives the movable seat 2 to move first, so that the elastic structure 3 clamps the object being shaken, the stop device 15 can first stop the base 1, and after the clamping is completed, the stop device 15 exits the stop state.

[0076] When a motor 6 is provided, the motor 6 can be directly or indirectly installed on the housing 12; as shown in the attached figure, both the base 1 and the motor 6 are directly installed on the base 13.

[0077] In some embodiments, the end of the elastic structure 3 can be hinged to at least one of the movable seat 2 and the base 1 around a pin; the elastic structure 3 is bent around a preset center line, and the pin is arranged parallel to the preset center line. This allows the end of the elastic structure 3 to rotate relative to the base 1 or the movable seat 2 to accommodate changes in the angle between the end and the base 1 or the movable seat 2 caused by the deformation of the elastic structure 3.

[0078] In some embodiments, to facilitate guiding the deformation of the elastic structure 3, the elastic structure 3 can be an elastic strip, wherein both ends of the elastic structure 3 are connected to the movable seat 2 and the base 1 respectively, so that it undergoes bending elastic deformation when the movable seat 2 approaches the base 1. It can be bent into an arc shape or other structures. By bending deformation, the clamping space is compressed. By using bending elasticity, the structure can be made more compact.

[0079] Taking the attached diagram as an example, the elastic strip can be straight or bow-shaped in its initial state. As the movable seat 2 moves towards the base 1, it pushes the two ends of the elastic strip closer together, so that the elastic strip becomes a bow-shaped structure or a bow-shaped structure with a greater degree of curvature.

[0080] In some embodiments, the end of the elastic strip can be hinged to at least one of the movable seat 2 and the base 1 around a pin. More preferably, both ends of the elastic strip are hinged to at least one of the movable seat 2 and the base 1 via pins, so that the end of the elastic strip can rotate relative to the base 1 or the movable seat 2 to accommodate changes in the angle between the end and the base 1 or the movable seat 2 caused by deformation of the elastic strip. Specifically, taking the bending of the elastic strip around a preset center line as an example, the pin can be arranged parallel to the preset center line. Alternatively, the pin can be arranged perpendicular to both the preset direction and the clamping direction.

[0081] As shown in the attached diagram, the elastic strip is a strip-shaped plate structure. Its two ends along the length direction L are connected to the base 1 and the movable seat 2, respectively. The thickness direction H of the strip-shaped plate structure is the clamping or loosening direction, which is consistent with the radial direction of the rotation of the base 1. At this time, the extension direction of the preset center line is consistent with the width direction K of the strip-shaped plate structure. The two ends of the elastic strip form pin holes 3-1.

[0082] In some embodiments, as shown in the accompanying drawings, for ease of installation, a receiving container 4 for accommodating baby bottles may be provided, wherein an elastic strip is embedded in a receiving groove 5 provided in the wall of the receiving container 4. This arrangement makes the structure more compact.

[0083] At this time, the specific preset direction can be the direction in which the opening of the receiving bucket 4 faces or the opposite direction; and as the movable seat 2 moves closer to the base 1 in the preset direction, the elastic strip protrudes and deforms into the cavity of the receiving bucket 4 to clamp the target object.

[0084] In some embodiments, multiple elastic structures 3 are evenly arranged around the cavity to push the target object towards the center, preventing the target object from deviating from the rotation axis of the base 1. Specifically, there may be two, three, or four elastic structures 3. As shown in the attached figures, two elastic strips may be provided, arranged opposite each other. During the clamping action, the upper ends of both elastic strips move downwards, causing the middle portions (distinguished from the upper and lower ends, which can be the center, slightly above, or slightly below) to deform and move closer to each other, thereby clamping the target object. During the releasing action, the upper ends of both elastic strips move upwards, causing the middle portions to deform and move further away from each other, thereby releasing the target object.

[0085] It should be noted that, of course, only one elastic structure 3 can be provided. In this case, the elastic structure 3 can cooperate with the base 1 or the wall of the receiving barrel 4 to form a clamping device to clamp and fix the target object.

[0086] In some embodiments, the preset direction can be perpendicular to the clamping direction of the elastic structure 3 to make the structure more compact. Specifically, the pin can be set perpendicular to both the preset direction and the clamping direction.
