When the installation needs again, only need with first drive shaft 3 directly insert establish in outer lane 21 or establish outer lane 21 cover on first drive shaft 3 can, need not to confirm installation direction, simple to operate.

In addition, utilize retaining member 2 as the part that first driveshaft assembly and shaft coupling body 1 are connected, the movable body 22 blocks the outer wall at first driveshaft assembly all the time when the shaft coupling is worked, can ensure the zero clearance between first driveshaft assembly and outer lane 21 to noise and vibration when can reducing the shaft coupling rotation.

It can be seen that for the use occasion that the reverse rotation of the coupler needs to be limited, the coupler can be protected through the locking piece 2.

In order to facilitate the installation of the movable body 22, a mounting groove may be formed in the outer ring 21, a mounting end of the movable body 22 is located in the mounting groove and contacts with an inner wall of the mounting groove, the movable body 22 can rotate in the mounting groove, and the mounting groove may be an annular groove, or at least one segment of the annular groove.

Further, in order to ensure that the movable body 22 is more reliably mounted and does not fall off the outer ring 21, the locking member 2 further includes:

a support frame 23 (as shown in fig. 3) disposed inside the outer ring 21, a movable passage of the movable body 22 being defined between the support frame 23 and an inner wall of the outer ring 21, the support frame 23 being provided with an opening through which the movable body 22 is exposed out of the support frame 23. The exposed end of the movable body 22 is used for contacting with the first driving shaft 3, the movable body 22 is guided by the supporting frame 23 and the movable body 22 is kept in the outer ring 21, no limit structure needs to be additionally processed on the inner walls of the movable body 22 and the positioning sleeve 21, the inner wall surface of the positioning sleeve 21 can be a smooth cylindrical surface, the structure is simple, the friction force is small, and therefore the heating value during working is relatively small.

In a specific embodiment, the supporting frame is annular and is arranged coaxially with the outer ring 21, so that the structure is compact, the stability of the supporting frame and the outer ring is ensured to be good after the supporting frame and the outer ring are assembled, and the rotation is more stable.

The number of the movable bodies 22 is not limited, and is at least one, such as one, two, three, four, etc., however, in order to avoid the stress concentration of the first driving shaft assembly, the number of the movable bodies 22 is preferably more than two. In order to apply a distributed and uniform locking force to the outer circumference of the first driveshaft assembly, two or more movable bodies 22 are distributed on the inner circumference of the outer ring 21.

Each of the movable bodies 22 is installed in each of the movable passages by an elastic member, and the elastic member maintains an initial position of the movable body 22 at an unlocking end. The elastic member may be a spring, which is convenient to process and install, and may provide a restoring force to the movable body 22 through the elastic member, so that the movable body 22 regularly rotates back and forth.

The spring form can be an annular strip-shaped reed, a compression spring or the like.

The material of the support frame 23 needs to have a certain strength, and also needs to have good thermal conductivity, small friction factor, good wear resistance, strong impact toughness and a linear expansion coefficient close to that of the movable body 22. The material of the support frame can be selected according to specific application occasions.

Specifically, the material of the support frame 23 may be low-carbon steel/stainless steel, bakelite/plastic, brass/bronze/aluminum alloy, or the like, and an appropriate material may be selected according to a specific use situation.

Thus, when the first drive shaft assembly is inserted into the outer race 21, the movable body 22 can have a floating clearance, ensuring that the movable body 22 does not press the first drive shaft assembly.

In this embodiment, the locking member 2 is a one-way locking member, which can realize one-way locking, for example, the locking member may be a one-way bearing, specifically, a wedge-type one-way bearing, and is used in a situation where the coupler is allowed to rotate in one direction.

To the occasion that needs the positive and negative direction of shaft coupling to rotate, can be equipped with coaxial and opposite direction's a pair of one-way retaining member in first connecting hole 11, for example two wedge type one-way bearings that set up in opposite directions to can realize the two-way locking of shaft coupling, first drive shaft subassembly can be with the synchronous corotation of shaft coupling or synchronous reversal, to the use occasion that needs the positive and negative rotation of shaft coupling, adopt to set up two opposite direction's wedge type one-way bearings in shaft coupling body 1 just can satisfy the requirement.

To the mounting means who sets up two one-way retaining member, the length that needs the first connecting hole 11 of extension in shaft coupling body 1 to satisfy the installation demand of two one-way retaining member, need closely laminate between two one-way retaining member, ensure the installation compactness.

When the first drive shaft assembly rotates towards the unlocking end of the exposed end, the unlocking end of the mounting end rotates to be in contact with the inner wall of the outer ring 21, at the moment, the movable body 22 is in an unlocking state, no acting force is applied to the first drive shaft assembly, and the first drive shaft assembly can freely rotate relative to the movable body 22. Thereby playing the role of unidirectional locking.

In order to securely fix the outer ring 21 in the first connection hole 11, the first connection hole 11 is a non-circular hole or at least a section of a non-circular hole, and the outer surface of the outer ring 21 is matched with the non-circular hole.
