Referring to fig. 1 to 4, in an embodiment, the first clutch structure includes a first clutch member 170 and a first contact block 142, the first clutch member 170 is fixed on a motor shaft of the sliding driving motor 120, a first driving block 171 is disposed on the first clutch member 170, the first contact block 142 is formed in an inner cavity of the first driving wheel 140, and during a rotation process of the first clutch member 170, the first driving block 171 and the first contact block 142 are circumferentially positioned or circumferentially separated.

In the manual mode, the handle assembly 240 brings the movable stroke member 160 to slide linearly relative to the housing assembly 110, and the first driving block 171 is circumferentially separated from the first contact block 142.

In this embodiment, the first clutch 170 is substantially disc-shaped, a spline connection may be adopted between the first clutch 170 and the motor shaft of the sliding driving motor 120, the first driving block 171 protrudes from an end surface of the disc-shaped main structure, and two first driving blocks 171 are arranged in a radial direction of the first clutch 170, and may be distributed at an angle of 180 degrees. The first driving wheel 140 is a substantially hollow cylinder structure, which is sleeved on the motor shaft of the sliding driving motor 120 and the outside of the first driving wheel 140, a first driving portion 141 is provided on the outer circumferential surface of the first driving wheel 140, a first contact block 142 is radially protruded on the cavity wall of the inner cavity, wherein two first contact blocks 142 are radially provided, and may be distributed at an angle of 180 degrees. When installed, the two first drive blocks 171 on the first clutch 170 are in the same plane of rotation as the two first contact blocks 142 on the first drive wheel 140. Thus, during operation, during the rotation of the first clutch member 170 driven by the motor shaft of the sliding driving motor 120, the two first driving blocks 171 thereon will be blocked by the two first contact blocks 142 on the first driving wheel 140, so as to achieve the circumferential positioning state.

And, above structural arrangement, in the drive process, the atress is even, and the operation is comparatively stable.

It is understood that, in the above process, the circumferential positioning state specifically refers to a state in which an interaction force is generated between the first driving block 171 and the second contact block 142, and the mutual abutting state causes the first clutch member 170, the first driving wheel 140 and the motor shaft of the sliding driving motor 120 to be linked. In the power-on state, initially, the first driving block 171 and the first contact block 142 may be in a state of contacting with each other, and the first contact block 142 directly abuts against the first driving block 171, or the first driving block 171 and the first contact block 142 may also be in a state of being separated from each other, and after the motor shaft of the sliding driving motor 120 rotates by a certain angle, the first driving block 171 and the first contact block 142 are in contact with each other against the idle stroke between them. The circumferentially separated state specifically refers to a state in which the first driving block 171 and the first contact block 142 are abutted against each other without generating a mutual acting force. In the above structure, when the handle assembly 240 is switched to the retracted position in the manual mode, and the first driving block 171 and the first contact block 142 are not blocked by the rotation of the first driving wheel 140, the included angle between the two first contact blocks 142 and the two first driving blocks 171 may be other than 180 degrees.

In the manual mode, the handle assembly 240 rotates the movable stroke member 160 relative to the housing assembly 110, and the second driving block 181 is circumferentially separated from the second contact block 152.

In this embodiment, the second clutch member 180 generally includes a cylinder and a disk connected to one end of the cylinder, the second clutch member 180 and the motor shaft of the rotary driving motor 130 may be connected by a spline on the cylinder, the second driving block 181 protrudes from an end surface of the disk, and two second driving blocks 181 are disposed in a radial direction of the second clutch member 180 and may be distributed at an angle of 180 degrees. The second driving wheel 150 is also substantially a hollow cylinder structure, which is sleeved on the motor shaft of the rotating driving motor 130 and the outside of the second driving wheel 150, a second driving part 151 is provided on the outer circumferential surface of the second driving wheel 150, and a second contact block 152 is radially protruded on the cavity wall of the inner cavity, wherein two second contact blocks 152 are also radially provided, and may be distributed at an angle of 180 degrees. When installed, the two second drive blocks 181 on the second clutch member 180 are in the same plane of rotation as the two second contact blocks 152 on the second drive wheel 150. In this way, during the operation process, the second clutch member 180 is driven by the motor shaft of the rotation driving motor 130 to rotate, the two second driving blocks 181 thereon will be blocked by the two second contact blocks 152 on the second driving wheel 150, so as to achieve the circumferential positioning state.

In the manual mode, when the handle assembly 240 is manually operated to rotate, because the second driving wheel 150 is driven by the handle assembly 240 to rotate relative to the second clutch member 180, the second driving block 181 and the second contact block 152 are separated from each other and become a circumferential separation state, so that when the rotation angle set by the switching between the throwing position and the withdrawing position of the handle assembly 240 is smaller than the rotation angle required by the second driving block 181 and the second contact block 152 to contact again, the second driving block 181 and the second contact block 152 are kept in the circumferential separation state in the whole process, the motor shaft of the sliding driving motor 120 cannot be caused to rotate by the second clutch member 180, and thus, when the handle assembly 240 is pulled, the resistance is smaller, and the operation is easier. And, above structural arrangement, in the drive process, the atress is even, and the operation is comparatively stable.

Similarly, in the above process, the circumferential positioning state specifically refers to a state in which an interaction force is generated between the second driving block 181 and the second contact block 152, and the interaction force is abutted against each other, and such a state causes the second clutch member 180, the second driving wheel 150, and the motor shaft of the rotary driving motor 130 to be linked. In the power-on state, initially, the second driving block 181 and the second contact block 152 may be in a state of contacting with each other, and the second contact block 152 directly abuts against the second driving block 181, or the second driving block 181 and the second contact block 152 may also be in a state of being separated from each other, and after the motor shaft of the rotary driving motor 130 rotates by a certain angle, the two contact each other by overcoming the idle stroke between the second driving block 181 and the second contact block 152. The circumferential separation state specifically refers to a state in which the second driving block 181 and the second contact block 152 are abutted against each other without generating an interaction force therebetween. In the above structure, when the handle assembly 240 is switched to the retracted position in the manual mode by the set rotation angle stroke, the rotation process of the second driving wheel 150 does not cause the second driving block 181 and the second contact block 152 to block each other, the included angle between the two second contact blocks 152 and the two second driving blocks 181 may be other than the exemplary 180 degrees.
