Background

With the development of science and technology, stirring equipment is increasingly applied to daily life of people, such as a flour-mixing machine, a soybean milk machine, a juice extractor, a wall breaking machine and the like. The stirring devices drive a stirring knife or a stirring blade and the like to stir through a driving shaft, and automatically cut and/or stir the materials.

However, in order to ensure that the conventional stirring blade or stirring blade can be reliably connected to the drive shaft when the drive shaft is rotated, and thus, the stirring blade or stirring blade is not likely to be thrown out of the stirring apparatus, it is often employed to fix the stirring blade or stirring blade to the drive shaft. The prior stirring knife or stirring blade is inconvenient to disassemble, and a great deal of time and energy are needed to be spent even if the stirring knife or stirring blade is disassembled; this results in the user having difficulty cleaning the stirring blade or blade and the bottom of the stirring device after using up the stirring device, which is one of the main pain points of the user.

Moreover, if a user directly puts his or her hand into the mixing device with the mixing blade for cleaning, the user is likely to cut his or her hand with the sharp blade, which is one of the main pain points of the user.

In addition, most of mixing devices include a mixing cup and a base, an output end of a power mechanism in the base is connected with a connecting end of a mixing component of the mixing container, and the power mechanism drives the mixing component to rotate so as to automatically cut and/or mix the materials in the mixing container.

However, the output end of the existing power mechanism and the connecting end of the stirring component are connected by matching the plurality of protrusions and the plurality of grooves, when the stirring cup is placed on the base, the plurality of protrusions and the plurality of grooves need to be accurately aligned, so that the position of the stirring cup needs to be continuously rotated to ensure that the plurality of protrusions can be inserted into the plurality of grooves, the installation is inconvenient, and even a long time is needed to accurately place the stirring cup on the base, which also becomes one of main pain points of users. In addition, in the stirring process of stirring equipment, the joint of the protrusion and the groove has large heat productivity, the requirement on the stirring time is high, the stirring time needs to be controlled in a short time, the heat dissipation is carried out on materials which are difficult to stir or cut up, even the materials need to be suspended for a period of time halfway, the stirring or the cutting is continued after the joint of the protrusion and the groove is cooled, and great inconvenience is brought to users. Moreover, the connection between the protrusion and the groove has a gap which is difficult to avoid, which causes a large noise and vibration during operation, which affects the user's feeling, and is one of the main pain points of the user.

The specific meaning of the above terms in the present invention can be understood as appropriate by those of ordinary skill in the art.

In addition, in the description of the present invention, "a plurality", and "a plurality" mean two or more unless otherwise specified.

As shown in fig. 1 and 2, in one aspect, an embodiment of the present invention provides a bidirectional locker 2, including:

the inner wall of the outer ring 21 is provided with a movable channel;

the movable bodies specifically comprise a first movable body 22 and a second movable body 23, the first movable body 22 and the second movable body 23 are both rotatably installed in the movable channel, the first movable body 22 and the second movable body 23 are both partially exposed out of the movable channel, the first movable body 22 and the second movable body 23 are both provided with a locking end and an unlocking end, the diameter of the first movable body 22 passing through the locking end is larger than that of the first movable body 22 passing through the unlocking end, and the diameter of the second movable body 23 passing through the locking end is larger than that of the second movable body 23 passing through the unlocking end; the direction in which the first movable body 22 rotates from its unlocking end toward the locking end is opposite to the direction in which the second movable body 23 rotates from its unlocking end toward the locking end, that is, the direction in which the first movable body 22 rotates from its locking end toward the unlocking end is opposite to the direction in which the second movable body 23 rotates from its locking end toward the unlocking end.

For example, the direction in which the first movable body 22 rotates from the unlocking end toward the locking end thereof is clockwise, and the direction in which the second movable body 23 rotates from the unlocking end toward the locking end thereof is counterclockwise; similarly, the direction of rotation of the first movable body 22 from the locking end toward the unlocking end is counterclockwise, and the direction of rotation of the second movable body 23 from the locking end toward the unlocking end is clockwise.

The bidirectional locking piece 2 can conveniently realize bidirectional locking and also can conveniently separate. Specifically, when the bidirectional locking member 2 is fitted over the driving assembly to be assembled, the first movable body 22 and the second movable body 23 are both in contact with the driving assembly. The driving assembly may be specifically the driving shaft 4, and may also be a structural member in which at least one shaft sleeve is sleeved on the driving shaft 4, and when the driving assembly is the driving shaft 4, the first movable body 22 and the second movable body 23 are in direct contact with the driving shaft 4; when the driving shaft 4 is externally fitted with a sleeve, the first movable body 22 and the second movable body 23 are in direct contact with the sleeve. The present invention will be described by taking a drive assembly as an example of the drive shaft 4.

Further, as shown in fig. 1 and 2, the arrow direction in fig. 1 and 2 indicates the rotation direction of the drive shaft 4, the arrow indicated to the left indicates the counterclockwise rotation of the drive shaft 4, and the arrow indicated to the right indicates the clockwise rotation of the drive shaft 4.

Specifically, the drive shaft 4 is rotated clockwise, the first movable body 22 is driven to rotate from the unlocking end to the locking end thereof, and the second movable body 23 is rotated from the locking end to the unlocking end thereof, so that the first movable body 22 is clamped on the outer periphery of the drive shaft 4, and the outer ring 21 is locked on the drive shaft 4; or, the driving shaft 4 rotates counterclockwise to drive the second movable body 23 to rotate from the unlocking end to the locking end, and at this time, the first movable body 22 rotates from the locking end to the unlocking end, so that the second movable body 23 is clamped on the periphery of the driving shaft 4, and the outer ring 21 is still locked on the driving shaft 4, thereby realizing bidirectional locking of the bidirectional locking member 2 and the driving shaft 4, and ensuring that the bidirectional locking member 2 can rotate synchronously with the driving shaft 4 in the forward and reverse directions; when the outer ring 21 fixes the rotating member externally, the rotating member can rotate in the forward and reverse directions in synchronization with the drive shaft 4.

When the bidirectional locking member 2 needs to be disengaged from the driving assembly, it is only necessary to rotate the outer ring 21 in the reverse direction by a slight angle, for example, about 10 degrees, so that the first movable body 22 is unlocked or the second movable body 23 is unlocked to release the locking of the driving assembly. Here, it should be noted that, when the first movable body 22 is unlocked, the second movable body 23 is not locked although moving from the unlocking end toward the locking end, and similarly, when the second movable body 23 is unlocked, the first movable body 22 is not locked although moving from the unlocking end toward the locking end; that is, both the first movable body 22 and the second movable body 23 are in the unlocked state. The bidirectional locking member 2 can be pulled out of the driving assembly, such as the driving shaft 4, only by applying a small force, so that the bidirectional locking member and the driving assembly are separated; for the case of fixing the rotating member outside the outer ring 21, it is convenient to detach the rotating member together with the bidirectional locking member 2 as a whole, and to clean the rotating member.
