The cylinder seat is fixed with the mounting substrate, the upper fluted disc rotates synchronously with the output shaft of the motor through the transmission flange, the lower fluted disc is connected with the shaft tube through a spline, and the torque is supported to be transmitted to the shaft tube while moving on the shaft tube. The lower fluted disc outputs braking or rotating torque to the shaft tube through meshing with the cylinder seat or the lower fluted disc, so that the functions of braking and transmission are realized. The torque is transmitted by adopting the mode of meshing the gear rings, so that the transmission effect is better due to rigid contact, and the lower gear ring is in a hollow structure because the meshing gear rings are positioned at the outer edge of the lower gear ring, so that the moment of inertia is larger, the corresponding angular acceleration is smaller, the load between the teeth is smaller, and the service life of the device is longer. Because the cylinder block is not movable, the axle tube is not movable when the lower toothed disc is engaged with the cylinder block, eliminating slip.
Preferably, the moving structure includes a piston structure and a spring structure disposed at both ends of the lower toothed disc. The piston structure and the spring structure provide axial thrust to the lower fluted disc, and the movement direction of the lower fluted disc is determined by the thrust difference of the piston structure and the spring structure to the lower fluted disc, which are opposite in direction.

Under this structure, when gas pressure disappears, under the elastic force effect of spring, lower fluted disc can remove to meshing cylinder seat position to realize the braking, make this device be the structure of normal closed, it is safer, avoid the secondary injury.
Preferably, the spring structure comprises a spring positioning hole arranged in the lower fluted disc and a spring arranged in the spring positioning hole, and the spring is abutted against a spring retainer ring fixedly connected to the shaft tube. The spring collar rotates synchronously with the shaft tube and is therefore stationary relative to the spring. During the movement, only axial pressure is born between the spring and the spring retainer ring.
Preferably, the spring positioning holes are distributed on the lower fluted disc at equal intervals along the circumferential direction. The structure ensures that the spring thrust force born by the lower fluted disc is more uniform, and the lower fluted disc is prevented from being blocked on the shaft tube.
Preferably, the driving flange and the shaft tube are provided with key grooves. The key slot is used for connecting the shaft body. With this structure, the clutch brake separates the power shaft of the connection device from the output shaft of the motor, and functions as a coupling.
Preferably, the cylinder block is rotatably connected with the shaft tube through a bearing; the upper fluted disc is rotationally connected with the shaft tube through a bearing. The cylinder block is through central siphon locating shaft pipe, and the upper fluted disc receives the support of central siphon through the bearing.

In some embodiments, the upper toothed disc 3 and the driving flange 5 are fixedly connected by a fastener, and are of a split structure, and in other possible embodiments, the upper toothed disc 3 and the driving flange 5 are of an integral structure.
The application adopts the form of arranging the meshing pool ring to brake and clutch. The cylinder seat 1 is fixed with the mounting substrate, the upper fluted disc 3 rotates synchronously with the output shaft of the motor through the transmission flange 5, the lower fluted disc 4 is connected with the spline 6 of the shaft tube 2, and the torque is supported to be transmitted to the shaft tube 2 while moving on the shaft tube 2. The lower fluted disc 4 outputs braking or rotating torque to the shaft tube 2 by being meshed with the cylinder seat 1 or the lower fluted disc 4, so that braking and transmission functions are realized. The torque is transmitted by adopting a gear ring meshing mode, so that the transmission effect is better due to rigid contact, and the lower gear ring 4 is of a hollow structure because the meshing gear ring 7 is positioned at the outer edge of the lower gear ring 4, so that the moment of inertia is larger, the corresponding angular acceleration is smaller, the load between the teeth is smaller, and the service life of the device is longer. Since the cylinder block 1 is not movable, the shaft tube 2 is not movable when the lower toothed disc 4 is engaged with the cylinder block 1, and slip can be eliminated. The two positions of the lower fluted disc 4 of the device respectively correspond to the transmission part and the braking part, and the binary structure eliminates the rotation problem generated when the shaft tube 2 and the equipment which are commonly used in the market are connected with each other to disconnect the input power.
