Description

Technical Field

[0001] The present invention relates to the technical field of electrical appliances, and more particularly to a milk shaker. Background Art

[0002] A milk shaker is a small electric device used to quickly mix or stir liquids. It is mainly used to mix milk powder, protein powder, beverages or other powdered substances with liquids. It mixes the powdered substances with water or other liquids by shaking or rotating quickly to avoid caking and ensure uniform mixing. However, the clamping mechanism of the existing milk shaker for fixing the milk bottle cannot be adjusted in size and cannot fix milk bottles of all sizes and shapes. Moreover, the clamping mechanism of the existing milk shaker cannot release the milk bottle after shaking the milk, which makes it inconvenient for the user to take the milk bottle.

[0035] In some embodiments, a milk shaker is provided, which mainly includes a milk shaking assembly for shaking the milk bottle placed therein to shake the milk. The milk shaking assembly generally includes a fixing device and a power device. The fixing device is used to fix the milk bottle so that the milk bottle is relatively fixed with the milk bottle, and then under the power action of the power device, the milk bottle is driven to shake. The fixing device is such as a clamping device, a clamping device, etc. In order to facilitate fixing the milk bottle, a receiving device is generally further provided. The receiving device has a receiving cavity for receiving the milk bottle, and the fixing device is used to relatively fix the milk bottle with the receiving device. The power device drives the receiving device to move, and the milk bottle in the receiving cavity of the receiving device will shake to achieve milk shaking. The specific shaking form can be selected according to needs, and the specific power device method can be set corresponding to the shaking form. The shaking form can be continuous rotation, or it can be a swing within a preset angle range, or it can be left and right swaying. Of course, it can also be other forms, as long as it can achieve milk shaking, so that the milk powder and water in the milk bottle are mixed evenly.

[0036] In some embodiments, the milk shaker mainly includes a base 1, a movable seat 2, a driving device, and an elastic structure 3.

[0037] The base 1 is mainly used to carry the target object to be clamped, such as a milk bottle. Specifically, the base 1 can be a part of the receiving device, such as the bottom of the receiving cavity. Further, the power device can also be made to drive the base 1 to move so that the target object shakes to achieve milk shaking.

[0038] Among them, the movable seat 2 is the object driven by the driving device. That is, the driving device is used to drive the movable seat 2 to move relative to the base 1 along a preset direction, so as to drive the elastic structure 3 to elastically deform through the movement of the movable seat 2. The movement mode is not limited, and it can be rotation or linear movement. As shown in the attached drawings, it is mainly linear movement. Specifically, the preset direction should correspond to the clamping direction or the loosening direction of the elastic structure 3, so as to be able to drive the elastic structure 3 to elastically deform to achieve the goal of clamping or loosening the target object.

[0039] The driving device can include a motor 6 and a transmission mechanism. The input end of the transmission mechanism is connected to the output shaft of the motor, and the output end is connected to the movable seat to drive the movable seat to move relative to the base along a preset direction. The transmission mechanism includes a lead screw nut transmission mechanism, gears, a crank rocker mechanism, a crank slider mechanism, a cam mechanism, etc., to facilitate corresponding driving by the motor.

[0040] Both ends of the elastic structure 3 are respectively connected to the base 1 and the movable seat 2, so that when the movable seat 2 moves relative to the base 1 in a preset direction, it can drive the elastic structure 3 to elastically deform to clamp or loosen the target object. This actually has at least the following three specific embodiments.

[0041] In some embodiments, when the movable seat 2 moves relative to the base 1 in a preset direction, it can drive the elastic structure 3 to elastically deform to clamp the target object; when the driving device stops driving the movable seat 2 and there is no restriction, under the action of the elastic deformation force of the elastic structure 3, it will reverse the deformation recovery, that is, recover the deformation in the direction of loosening the target object. At this time, the movable seat 2 can move in the reverse direction of the preset direction correspondingly.

[0042] In some other embodiments, when the movable seat 2 moves relative to the base 1 in a preset direction, it can drive the elastic structure 3 to elastically deform to loosen the target object; when the driving device stops driving the movable seat 2 and there is no restriction, under the action of the elastic deformation force of the elastic structure 3, it will reverse the deformation recovery, that is, recover the deformation in the direction of clamping the target object. At this time, the movable seat 2 can move in the reverse direction of the preset direction correspondingly.

[0043] In some other embodiments, when the movable seat 2 moves relative to the base 1 along a preset direction, it can drive the elastic structure 3 to elastically deform to clamp the target object; when the driving device stops driving the movable seat 2, the elastic structure 3 can maintain the elastic deformation to elastically clamp the target object. When the movable seat 2 moves relative to the base 1 in the reverse direction of the preset direction, it can drive the elastic structure 3 to recover the deformation in the direction of elastic deformation recovery to loosen the target object. That is, at this time, whether the elastic structure 3 clamps or loosens the target object is achieved by the driving of the driving device.

[0044] When the elastic structure 3 deforms, it realizes clamping or loosening the target object. The main implementation forms are as follows: Due to elastic deformation, at least part of the structure of the elastic structure 3 will move along the clamping direction, so that the clamping space becomes smaller, enabling the target object to be clamped and restricting the position of the target object; at least part of the structure of the elastic structure 3 moves along the loosening direction, so that the clamping space becomes larger, and at this time the target object can move freely without being restricted. As shown in the attached drawing, when the convex part of the elastic structure 3 moves towards the accommodation cavity, clamping is achieved, and when it moves away from the accommodation cavity, loosening is achieved. Among them, the convex part of the elastic structure 3 is the structural part used to contact the target object.

[0045] Among them, the form of the elastic structure 3 is not specifically required, as long as it can elastically deform to enable at least part of the structure, especially the structure of the target object that needs to be contacted, to move along the clamping direction or along the loosening direction.

[0046] In the above embodiment, the loosening or clamping of the target object is realized by the driving of the elastic structure 3 and the driving device. Since the driving device drives the elastic structure 3 to deform, the clamping effect of the elastic structure 3 can be well controlled, and it is convenient to actively change the deformation state of the elastic structure 3, so that the clamping device can present a clamping state and a loosening state. Moreover, in the clamping state, because of the elastic clamping of the elastic structure 3, the adaptability to the target object is better, so that it can adapt to more sizes of target objects, making the clamping operation of the target object convenient. To sum up, the above milk shaker can effectively solve the problem that the clamping operation of the target object of the milk shaker is inconvenient.

[0047] In some embodiments, in order to facilitate driving, the transmission mechanism can include at least one lead screw 7. The lead screw 7 is rotatably arranged on the base 1 around its own axis and is restricted from moving relative to the base 1 along the axial direction of the lead screw 7, so that the lead screw 7 can only rotate relative to the base 1 around its own axis. The movable seat 2 is provided with a threaded hole 8 that is in threaded cooperation with the lead screw 7, and the threaded hole 8 and the lead screw 7 form a lead screw nut transmission mechanism. The movable seat 2 is restricted from rotating with the lead screw 7 and can only move relative to the base 1 along the axis of the lead screw 7. The movable seat 2 is restricted from rotating with the lead screw 7: It can be through the limiting structure fixed on the base 1 to prevent rotation relative to the base 1, thereby preventing rotation with the lead screw 7; it can also be through the cooperation of multiple parallel lead screws 7 and threaded holes 8 to achieve restriction and prevent the movable seat 2 from rotating with the lead screw 7.

[0048] It should be noted that the thread fit between the lead screw 7 and the threaded hole 8 can be a self-locking thread fit or a non-self-locking thread fit. When a self-locking thread fit is used, the reverse movement of the movable seat 2 relative to the base 1 in the preset direction is also driven by a driving device or another mechanism. When a non-self-locking thread fit is adopted, at this time, the reverse movement of the movable seat 2 relative to the base 1 in the preset direction can be based on the elastic deformation force of the elastic structure 3.

[0049] Through the transmission of the above lead screw and nut transmission mechanism, when the lead screw 7 rotates, it can drive the movable seat 2 to move along the axial direction of the lead screw 7, that is, the movable seat 2 can move relative to the base 1 in the preset direction. The preset direction is a direction along the axial direction of the lead screw 7. As shown in the attached drawing, the base 1 and the movable seat 2 are arranged in parallel along the axial direction of the lead screw 7. When the base 1 and the movable seat 2 are arranged in parallel in the preset direction, at this time, the preset direction: can be the direction in which the movable seat 2 moves closer to the base 1. At this time, when the two ends of the elastic structure 3 move closer to each other, the elastic structure 3 undergoes elastic deformation; it can also be the direction in which the movable seat 2 moves away from the base 1. At this time, when the two ends of the elastic structure 3 move away from each other, the elastic structure 3 undergoes elastic deformation.

[0050] 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 driving devices. As shown in the attached drawing, the driving device includes a motor 6.

[0051] In some embodiments, for the convenience of transmission, generally a transmission gear set is provided between the rotation driving device (such as the motor 6 in the following text) and the lead screw 7. Specifically, the transmission gear set can include a central gear 9 and a transmission gear 10 that are engaged with each other, so that the rotation driving device 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.

[0052] As described above, one or more lead screws 7 can be provided. For example, when one lead screw 7 is provided, for the convenience of transmission, it can be a combination of one lead screw 7 and multiple guide rods arranged around an object, such as around the receiving barrel 4 formed on the base 1, where the receiving barrel 4 is used to receive a baby bottle. When multiple lead screws 7 are provided, for the convenience of transmission, multiple lead screws 7 can be used to surround an object, such as around the receiving barrel 4.

[0053] In some embodiments, the movable seat 2 can be an annular seat. In the middle of the annular seat, there is a receiving cavity for receiving the target object so that the movable seat can be sleeved on the target object. For example, the annular seat is sleeved on the outside of the receiving barrel 4. On the annular seat, in the circumferential direction: one or more lead screws 7 can be arranged. As shown in the attached drawing, two lead screws 7 can be arranged and are respectively located on the transverse two sides of the receiving barrel 4; one or more elastic structures 3 can be arranged. As shown in the attached drawing, four elastic structures can be arranged. For the convenience of setting, it is preferably that one end of the elastic structure is connected to the annular seat and the other end is connected to the edge part of the base; one end of the lead screw is connected to the threaded hole of the annular seat and the other end is rotatably connected to the edge part of the base.

[0054] In some embodiments, for the convenience of transmission, transmission gears 10 can be fixed to the ends of the respective lead screws 7. Each transmission gear 10 is arranged around the central gear 9 to respectively mesh with the central gear 9. By rotating the central gear 9, each transmission gear 10 can be driven to rotate, so that each lead screw 7 rotates synchronously, and the movable seat 2 is driven to move up and down synchronously. As shown in the attached drawing, when two lead screws 7 are provided, they are respectively located on the two sides in the radial direction of the central gear 9. Correspondingly, transmission gears 10 are respectively arranged on the two sides in the radial direction of the central gear 9. The transmission gear 10 is fixedly connected to the corresponding lead screw 7 and is coaxially arranged.

[0055] For the convenience of arrangement, the central gear 9 can be arranged at the bottom of the receiving barrel 4, for example, on the side of the base 1 away from the receiving cavity.

[0056] For the convenience of driving the central gear 9 to rotate and to avoid excessive space occupation in the up and down direction, the motor 6 and the receiving barrel 4 can be arranged side by side in the horizontal direction, and 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 is elastically deformed to clamp or loosen the target object.

[0057] In some embodiments, it further includes a housing 12. The base 1 is rotatably directly or indirectly installed on the housing 12. By rotating the base 1, the feeding bottle on it is driven to rotate to realize milk shaking. It should be noted that: the base 1 is rotatably directly installed on the housing 12, for example, they are directly rotationally matched with each other so that the base 1 can rotate relative to the housing 12; the base 1 is rotatably indirectly installed on the housing 12, and a base 13 relatively fixed to the housing 12 can be further provided, and the base 1 is rotatably installed on the base 13, thereby realizing the indirect rotational installation of the base 1 on the housing 12.

[0058] The rotation axis of the central gear 9 coincides with the rotation axis of the base 1. When a torque is applied to the central gear 9, therefore, at this time, the central gear 9 can first drive the transmission gear 10 to rotate. When the elastic structure 3 clamps the target object, the transmission gear 10 cannot further rotate relative to the base 1, then the rotation of the central gear 9 relative to the base 1 will also be restricted. At this time, the torque of the central gear 9 can be transmitted to the base 1 to drive the base 1 to rotate, thereby realizing milk shaking. Specifically, both the central gear 9 and the transmission gear 10 can be directly or indirectly rotatably connected to the base 1. When a motor 6 is provided, the motor 6 can be directly or indirectly mounted on the housing 12; as shown in the attached drawing, both the base 1 and the motor 6 are directly mounted on the base 13.

[0059] In some embodiments, in order to facilitate guiding the deformation of the elastic structure 3, the elastic structure 3 can be an elastic strip. The two ends of the elastic structure 3 are respectively connected to the movable seat 2 and the base 1, so as to undergo bending elastic deformation when the movable seat 2 approaches the base 1. It can be bent in an arc shape or bent into other structures. By bending deformation, the clamping space can be compressed. Through bending elasticity, the structure can be made more compact.

[0060] Taking the attached drawing as an example, in the initial state, the elastic strip can be in a straight line shape or an arc shape. During the process of the movable seat 2 moving towards the base 1, the two ends of the elastic strip are pushed closer to each other, so that the elastic strip becomes an arc-shaped structure or an arc-shaped structure with a greater degree of bending.

[0061] 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 shaft. A more optional solution is that the two ends of the elastic structure 3 are respectively hinged to at least one of the movable seat 2 and the base 1 through a pin shaft, so that the end of the elastic strip can rotate relative to the base 1 or the movable seat 2 to adapt to the angle change between the end and the base 1 or the movable seat 2 caused by the deformation of the elastic structure 3. Specifically, taking the elastic structure 3 bending around a preset center line as an example, the pin shaft can be arranged parallel to the preset center line. It can also be that the pin shaft is perpendicular to both the preset direction and the clamping direction.

[0062] As atta Figure 5 Shown in the attached drawing, the elastic strip is a strip plate structure. The two ends along the length direction L are respectively connected to the base 1 and the movable seat 2, and the thickness direction H of the strip plate structure is the clamping direction or the loosening direction, which is consistent with the radial direction of the rotation of the base 1. At this time, the extending direction of the preset center line is consistent with the width direction K of the strip plate structure. The two ends of the elastic strip form pin holes 3-1.

[0063] In some embodiments, as shown in the accompanying drawings, for convenience of setting, a receiving barrel 4 for receiving a baby bottle may be provided, wherein an elastic strip is embedded in a receiving groove 5 provided in the barrel wall of the receiving barrel 4. Through the above setting, the structure can be made more compact.

[0064] At this time, the specific preset direction may be the direction of the opening of the receiving barrel 4 or the opposite direction; and when the movable seat 2 moves closer to the base 1 along the preset direction, the elastic strip bulges and deforms into the receiving cavity of the receiving barrel 4 to clamp the target object.

[0065] In some embodiments, a plurality of elastic structures 3 are uniformly arranged around the receiving cavity to push the target object towards the middle and prevent the target object from deviating from the rotation axis of the base 1. Specifically, for example, two, three or four elastic structures 3 may be provided. As shown in the accompanying drawings, two elastic strips may be provided. The two elastic strips are arranged oppositely. When performing the clamping action, the upper ends of the two elastic strips both move downward, so that the middle parts (different from the upper and lower ends, which may be the middle, upper or lower parts) of the two elastic strips move in the direction of approaching each other to clamp the target object. When performing the loosening action, the upper ends of the two elastic strips both move upward, so that the middle parts of the two elastic strips move in the direction of moving away from each other to loosen the target object.

[0066] It should be noted that, of course, only one elastic structure 3 may be provided. At this time, the elastic structure 3 may cooperate with the base 1 or the barrel wall of the receiving barrel 4 to form a clamping device in combination to clamp and fix the target object.

[0067] In some embodiments, the preset direction may be perpendicular to the clamping direction of the elastic structure 3 to make the structure more compact. Specifically, for example, the pin shaft may be perpendicular to the preset direction and the clamping direction in pairs.

[0068] In some embodiments, a milk shaker is provided, which mainly includes a housing 12, a base 1, a motor 6, a movable seat 2, an elastic structure 3, a lead screw 7 and a stop device 15.

[0069] The base 1 may be a disk structure. A receiving barrel 4 is provided on the base 1. The two may be integrally formed or assembled to form a relatively fixed relationship. The receiving cavity (the barrel cavity of the receiving barrel 4) of the receiving barrel 4 is used to place the target object, such as a baby bottle. The upper side of the receiving barrel 4 is open to serve as the target object placement opening. The receiving barrel 4 is cylindrical, or approximately cylindrical. The central axis of the receiving barrel 4, that is, the rotation axis of the base 1. For the convenience of description, the rotation axis of the base 1 is the central axis. The base 1 is rotatably mounted on the housing 12 around the central axis, and may be directly mounted or indirectly mounted.

[0070] Among them, a limiting member 14 is provided on the base 1 to facilitate cooperation with the stopping device 15. When the stopping device 15 enters the stopping state to limit the limiting member 14, it prevents the base 1 from rotating relative to the housing 12, and further prevents the receiving barrel 4 from rotating. Specifically, the stopping device 15 can include a stopping member and a power member. Among them, the power member 15-2 is a moving driving device for driving the stopping member 15-1 to move in and out of the stopping state. For example, the power member 15-2 is an electromagnet, and the stopping member 15-1 is an iron core or a part of the iron core, or can also be a structure fixedly installed on the iron core. The limiting member 14 can be a toothed ring formed at the edge of the base 1. When the stopping member 15-1 is engaged in the tooth groove of the toothed ring, it can prevent the base 1 from rotating. Of course, the stopping device 15 is not limited to this, as long as it can prevent the base 1 from rotating.

[0071] Among them, the movable seat 2 is annularly sleeved on the receiving barrel 4 and is located above the base 1. The movable seat 2 can move up and down, and moving downward is moving along a preset direction. The edge of the base 1 protrudes from the receiving barrel 4 and is arranged opposite to the movable seat 2.

[0072] Each elastic structure 3 is an elastic strip. The upper end is hinged to the lower side of the movable seat 2, and the lower end is hinged to the upper side of the edge of the base 1. And the extending direction of the hinge axis is the circumferential direction of the central axis to adapt to the bending deformation of the elastic strip. Specifically, pin holes are formed by curling the two ends of the elastic strip to form a rotational fit with the hinge axis.

[0073] The receiving barrel 4 has a receiving groove 5 that fits the elastic strip. The receiving groove 5 is provided with a through hole inside and outside the barrel, so that the upper and lower ends of the elastic strip are located outside the receiving barrel 4, and the middle part passes through the receiving groove 5 to be able to move into the receiving cavity. The elastic strip is bent into an arc shape, and the middle part protrudes into the receiving cavity, so that when the upper and lower ends are pressed, the bending degree of the elastic strip increases, and the protruding degree of the middle part into the barrel cavity increases. As shown in the attached drawing, a plurality of elastic structures are arranged around the receiving cavity. When the bending degree increases simultaneously, the middle parts protrude into the receiving cavity simultaneously to reduce the clamping space and clamp the target object. Specifically, for example, four elastic strips can be arranged evenly around the central axis.

[0074] When the movable seat 2 is in the initial position, at this time, the distance between the movable seat 2 and the base 1 is the farthest. At this time, the elastic strip is in a small arc state, and the middle part protrudes toward the central axis to guide the bending of the elastic strip.

[0075] When the movable seat 2 moves closer to the base 1, that is, moves downward, the lower ends of the elastic strip members are pressed and move downward simultaneously. At this time, the bending degree of the elastic strip members increases. And since the upper and lower ends of the elastic strip members are defined by the hinge shafts and cannot move in the radial direction of the central axis; therefore, as the bending degree increases, the middle part of the elastic strip members will protrude more towards the central axis direction, and the middle parts of the elastic strip members will approach the central axis. Thus, the combined clamping opening (which can also be called the clamping space) will become smaller until the elastic strip members abut against the target object and are restricted by the target object, and the movable seat 2 cannot cause the elastic strip members to deform further, then the movable seat 2 will stop moving downward. Of course, it can also be through a sensor to stop the movable seat 2 from moving downward when it detects that the clamping is in place.

[0076] The lower end of the lead screw 7 is rotationally connected to the base 1 around its own axis, and the base 1 and the lead screw 7 are relatively fixed in the axial direction of the lead screw 7. A threaded hole 8 is provided on the movable seat 2, and the threaded hole 8 and the lead screw 7 form a threaded fit to be used to form a lead screw-nut transmission mechanism. The rotation axis of the lead screw 7 is arranged parallel to the central axis. A plurality of lead screws 7 are evenly arranged around the central axis on the outside of the receiving barrel 4. Considering the spatial position of the transmission gear 10, generally only two or three lead screws 7 are provided. As shown in the attached drawing, the two lead screws 7 are respectively arranged on the radial two sides of the receiving barrel 5. When the lead screw 7 rotates, the lead screw 7 remains unchanged in the up and down position relative to the base 1, which will cause the movable seat 2 to move up and down. According to the different rotation directions of the lead screw 7, the movable seat 2 will move up or down correspondingly. A self-locking threaded fit is preferably adopted between the lead screw 7 and the threaded hole 8.

[0077] On the lower side of the base 1, a transmission gear 10 is fixed to the lower end of the lead screw 7, and a central gear 9 is provided at the center of the lower side of the base 1. The central gear 9 can rotate relative to the base 1 around the central axis, such as directly or indirectly achieving a rotational connection. The transmission gear 10 rotates synchronously with the lead screw 7, and each transmission gear 10 is arranged around the central gear 9 and meshes with the central gear 9, so that the central gear 9 rotates, drives the transmission gear 10 to rotate, and the corresponding lead screw 7 rotates simultaneously to push the movable seat 2 downward or upward in the same direction.

[0078] The transmission between the central gear 9 and the motor 6 can be through gear transmission, or as shown in the attached drawing through a belt transmission mechanism 11. The motor 6 can be relatively fixed to the housing 12, such as fixedly installed on the housing 12.

[0079] During use, in the initial state, the movable seat is in the initial position, and the clamping space is the largest, and the target object can be placed in the receiving cavity. At this time, the stop device 15 enters the stop state, making the base 1 unable to rotate.

[0080] Then start the motor. When the main shaft of the motor 6 drives forward, it drives the central gear 9 to rotate. At this time, since the base 1 is prevented from rotating relative to the housing 12, the transmission gears 10 all rotate simultaneously, and the corresponding lead screws 7 all rotate simultaneously. Each lead screw 7 makes the movable seat 2 move downward through the threaded hole 8. The movable seat 2 and the base 1 respectively apply forces to the upper and lower ends of the elastic strip to increase the bending degree of the elastic strip. During the bending process, the upper and lower ends adaptively rotate relative to the movable seat 2 and the base 1 respectively around the corresponding hinge axes, and the bulging degree of the middle part of the elastic strip towards the central axis increases. As the movable seat 2 continues to move downward, the elastic strip continues to deform until the middle part of the elastic strip abuts against the object to be clamped and clamping is achieved. When the movable seat 2 cannot make the elastic strip continue to deform, the object to be clamped is completely clamped and the motor 6 stalls.

[0081] At this time, make the stop device 15 exit the stop state and no longer prevent the base 1 from rotating relative to the housing 12, so that the motor 6 stops stalling, and push the base 1 to rotate around the central axis, thereby realizing milk shaking.

[0082] After the milk shaking is completed, the motor 6 stops rotating, and then make the stop device 15 enter the stop state to lock the base 1 and prevent the base 1 from rotating relative to the housing 12. Then the main shaft of the motor 6 rotates in the reverse direction. At this time, the torque is transmitted to the transmission gear 10. The transmission gear 10 can rotate in the opposite direction relative to the base 1, so that the lead screw 7 applies an upward thrust to the movable seat 2 through the threaded hole 8. The movable seat 2 moves upward, causing the upper end of the elastic strip to move upward, that is, the elastic strip deforms in the direction of restoring deformation. At this time, the bulging degree of the middle part becomes smaller, that is, it moves in the direction away from the central axis. At this time, the clamping space gradually increases until the object to be clamped is released. Then the movable seat 2 continues to move upward to return to the initial position. The motor 6 stops reversing, which can be achieved by the upper limit structure of the base 1 or the receiving barrel 4 preventing the movable seat 2 from continuing to move upward after it moves upward in place. At this time, the motor 6 stalls to stop driving.
