[0021] In an embodiment of the present utility model, an electric actuator convenient for installation includes an actuator 1, a screw thread 2, and a nut ③. The screw thread 2 is fixedly connected to the actuator 1. The nut 3 is sleeved outside the screw thread 2 and a driven gear 4 is fixedly connected to one side thereof. A driving gear 5 is rotatably connected to one side of the actuator 1. The outer periphery of the driving gear 5 is long teeth 11, and the outer periphery of the driven gear 4 is short teeth 12. The long teeth 11 are adapted to the short teeth 12.

[0022] Another embodiment of the present utility model: An electric actuator convenient for installation, wherein a mounting seat 8 is fixedly connected to one side of the actuator 1, and a motor 9 is fixedly installed on one side of the mounting seat 8. The output end of the motor 9 passes through the mounting seat 8 and is fixedly connected to the driving gear 5.

[0023] Since the screw thread 2 is fixedly connected to the actuator 1, the nut 3 is sleeved outside the screw thread 2, a driving gear 5 is rotatably connected to one side of the actuator 1, the outer periphery of the driving gear 5 is provided with long teeth 11, the outer periphery of the driven gear 4 is provided with short teeth 12 and the long teeth 11 are adapted to the short teeth 12. Therefore, by driving the driving gear 5 to rotate through the motor 9, the short teeth 12 outside the driving gear 5 move and drive the long teeth 11 outside the driven gear 4 to rotate. Since there is a height difference between the short teeth 12 and the long teeth 11, and the nut 3 is screwed to the screw thread 2, the rotation of the driving gear 5 can drive the nut 3 to continuously rotate along the axial direction of the screw thread 2 and fasten the screw thread 2 to the connected screw thread, so that it is not necessary for personnel to use a wrench to fasten the nut 3, facilitating the disassembly and assembly of the actuator.

[0024] Another embodiment of the present utility model: An electric actuator convenient for installation further includes a protective cover 6, and the driven gear 4, the driving gear 5, the mounting seat 8 and the motor 9 are all accommodated inside the protective cover 6.

[0027] Another embodiment of the present utility model: An electric actuator convenient for installation, the protective cover 6 is made of high-strength alloy steel with a long service life.

[0028] The working principle of the present utility model is: Since the screw thread 2 is fixedly connected to the actuator 1, the nut 3 is sleeved outside the screw thread 2, a driving gear 5 is rotatably connected to one side of the actuator 1, the outer periphery of the driving gear 5 is provided with long teeth 11, the outer periphery of the driven gear 4 is provided with short teeth 12 and the long teeth 11 are adapted to the short teeth 12. Therefore, by driving the driving gear 5 to rotate through the motor 9, the short teeth 12 outside the driving gear 5 move and drive the long teeth 11 outside the driven gear 4 to rotate. Since there is a height difference between the short teeth 12 and the long teeth 11, and the nut 3 is screwed to the screw thread 2, the rotation of the driving gear 5 can drive the nut 3 to continuously rotate along the axial direction of the screw thread 2 and fasten the screw thread 2 to the connected screw thread, so that it is not necessary for personnel to use a wrench to fasten the nut 3, facilitating the disassembly and assembly of the actuator.
