A manipulator includes a mechanical arm, a cable positioned in the mechanical arm, at least one cable protection device, and a plurality of fasteners. The at least one cable protection device is fixed to the mechanical arm by the fasteners. The mechanical arm defines a receiving slot, in which the cable is partially received. The at least one cable protection device includes a fixing member and a resilient arm. The fixing member is connected to the mechanical arm, opposite to the receiving slot. The resilient arm is capable of swinging relative to the fixing member.
1. A manipulator, comprising:
a robotic mechanical arm defining a receiving slot;
a cable connecting to the mechanical arm and received in the receiving slot; and
at least one cable protection device comprising a fixing member comprising a base plate and two fixing portions extending from the base plate, and a resilient arm extending from the base plate at an angle located between the two fixing portions, wherein the base plate is located across the receiving slot, and the two fixing portions are respectively fixed to the mechanical arm at two sides of the receiving slot; the resilient arm comprises a main body and two restricting portions extending from opposite sides of the free end of the main body, the cable is located between the base plate and the resilient arm of the cable protection device and the mechanical arm, and the resilient arm is capable of swinging relative to the base plate.
2. The manipulator of claim 1 , wherein the fixing member defines at least one positioning slot; the mechanical arm defines at least one fixing hole; and the manipulator further comprises at least one fastener extending through the at least one positioning slot and the at least one fixing hole to connect with the at least one cable protection device.
3. The manipulator of claim 2 , wherein a diameter of the shaft of the fastener is substantially the same as the width of the positioning slot, but less than a length of the positioning slot.
4. The manipulator of claim 1 , wherein the at least one cable protection device comprises two cable protection devices, respectively positioned at opposite ends of the receiving slot.
5. The manipulator of claim 1 , wherein the fixing member and the resilient arm are integrally formed.
6. The manipulator of claim 1 , wherein the mechanical arm defines at least one connecting slot.
7. The manipulator of claim 6 , wherein the at least one connecting slot comprises two connecting slots, respectively arranged at two ends of the mechanical arm.
8. A manipulator, comprising:
A robotic mechanical arm defining a receiving slot;
a cable connected to the mechanical arm and received in the receiving slot; and
at least one cable protection device comprising a fixing member comprising a base plate and two fixing portions extending from the base plate, and a resilient arm extending from the base plate located between the two fixing portions, wherein the base plate is located across the receiving slot, and the two fixing portions are respectively fixed to the mechanical arm at two sides of the receiving slot; the resilient arm comprises a main body and two restricting portions extending from opposite sides of the free end of the main body, the resilient arm elastically contacts the cable, and the resilient arm is capable of swinging relative to the base plate.
9. The manipulator of claim 8 , wherein at least one opening is formed between the resilient arm and the mechanical arm, and at least one end of the cable extends outside of the receiving slot through the at least one opening.
10. The manipulator of claim 9 , wherein the at least one cable protection device comprises two cable protection devices, respectively positioned at opposite ends of the receiving slot; the at least one opening comprises two openings, out of which opposite ends of the cable correspondingly extend outside of the receiving slot.
11. The manipulator of claim 8 , wherein the fixing member and the resilient arm are integrally formed.
