[0028] Reference Figure 1-2The utility model provides an embodiment: an electric tractor, comprising a handle grip 1, a tractor body 2 is arranged at the top of the handle grip 1, a rear end of the tractor body 2 is connected to a rear end connecting end 3, a handle switch 5 is connected to the front end of the tractor body 2, a battery 4 is installed inside the bottom of the handle grip 1, a handle switch 5 is arranged on the outer wall of the handle grip 1, one end of the front end connecting end 6 is connected to a fixing sleeve 7, one end of the fixing sleeve 7 is connected to a telescopic sleeve 8, a screw 9 is arranged inside the telescopic sleeve 8, a limiting slide groove 10 is arranged on the outer wall of the telescopic sleeve 8, and a pin hole 11 is arranged on the outer wall of the fixing sleeve 7.

[0029] Specifically, the screw rod 9 is connected to the motor transmission of the traction device body 2, and the screw rod 9 is threadedly connected to the inside of the telescopic sleeve 8. The telescopic sleeve 8 can be limited by the setting of the limiting slide groove 10 and the pin hole 11. During installation, the pin is inserted into the inside of the pin hole 11, and then connected to the limiting slide groove 10 for limiting, so that the telescopic sleeve 8 will not rotate under the drive of the screw rod 9, but will only move back and forth along the fixed sleeve 7, thereby realizing the function of traction and telescoping.

[0030] In the present invention, the tractor body 2 is fixedly mounted on the top of the handle grip 1, and a motor is installed inside the tractor body 2. The motor serves as the power source of the tractor body 2 and provides stable and powerful power for the entire traction device. The fine design of the motor inside the body ensures its efficient and low-noise operation, so that users can enjoy a more comfortable experience during use.

[0031] Driven by the motor, the tractor body 2 transmits power to the working parts of the tractor through a series of mechanical transmission devices. These working parts, driven by the motor, accurately perform traction actions to provide users with accurate traction force and angle.

[0032] Furthermore, the battery 4 is fixedly installed inside the handle grip 1 , the handle switch 5 is movably connected to the outer wall of the handle grip 1 , and the size of the battery 4 is smaller than the size of the handle grip 1 .

[0033] Furthermore, the rear end connection end 3 is integrally connected to one end of the tractor body 2, and the front end connection end 6 is integrally connected to the other end of the tractor body 2. The rear end connection end 3 has the same size as the front end connection end 6. The rear end connection end 3 is used as an interface between the tractor and various devices. Its integrated design not only simplifies the installation steps, but also enhances the reliability of the connection, ensuring that it will not loosen or fall off during the traction process. At the same time, its size is consistent with the front end connection end 6, reflecting the designer's careful consideration of details, making the overall appearance more coordinated and unified.

[0034] The front connection end 6 is integrally connected to the other end of the handle grip 1, providing the user with a convenient control experience. The user can easily control the tractor by holding the handle grip 1, whether it is adjusting the direction or controlling the speed, it can be done with ease. The design of the front connection end 6 also focuses on stability and durability to ensure that it can maintain good performance during long-term use.

[0035] Further, the fixed sleeve 7 is fixedly mounted on one end of the front connecting end 6, and threads are provided on the outer walls of both ends of the fixed sleeve 7, and the telescopic sleeve 8 is movably connected inside the fixed sleeve 7, and the size of the fixed sleeve 7 is larger than that of the telescopic sleeve 8, so that the telescopic sleeve 8 can be freely telescoped inside the fixed sleeve 7. At the same time, in order to increase the stability of the telescopic sleeve 8 in the fixed sleeve 7, a sliding groove matching the outer wall of the telescopic sleeve 8 is provided on the inner wall of the fixed sleeve 7, which can effectively prevent the telescopic sleeve 8 from deflecting or shaking during the telescopic process.

[0036] Furthermore, the screw rod 9 is movably connected to the inside of the telescopic sleeve 8, the inside of the telescopic sleeve 8 is provided with a thread, the limiting slide groove 10 is provided on the outer wall of the telescopic sleeve 8, the latch hole 11 is provided on the outer wall of the fixed sleeve 7, the number of the latch holes 11 is two, the telescopic sleeve 8 can limit the screw rod 9, and as the screw rod 9 rotates inside the telescopic sleeve 8, the telescopic sleeve 8 is provided with a matching thread inside, so that the telescopic sleeve 8 can telescope along the axial direction of the screw rod 9. This telescopic movement not only enables the entire device to flexibly adapt to different working scenes, but also can achieve accurate positioning of the screw rod 9 by adjusting the length of the telescopic sleeve 8.

[0037] The design of the limiting slide groove 10 is to further enhance the stability of the telescopic sleeve 8. When the telescopic sleeve 8 is extended and retracted on the screw rod 9, the limiting slide groove 10 can ensure that the telescopic sleeve 8 always remains on the correct track to avoid deviation or distortion.

[0038] Working principle and usage process:

[0039] When using the electric tractor of the utility model, the user first holds the entire tractor by the handle 1, and starts the motor by operating the handle switch 5. After the motor is started, the screw 9 is driven to rotate through the transmission mechanism. Since the screw 9 is matched with the thread inside the telescopic sleeve 8, when the screw 9 rotates, the telescopic sleeve 8 will move forward and backward along the fixed sleeve 7 driven by the screw 9. Such a design realizes the telescopic function of the tractor, which can be adjusted according to the needs of the user.

[0040] During the movement of the telescopic sleeve 8, the pin is inserted into the pin hole 11 and is connected to the limiting slide groove 10 for limiting, so that the telescopic sleeve 8 can only move forward and backward without rotating under the drive of the screw rod 9. Such a design ensures the stability and safety of the tractor during use.

[0041] In addition, the battery 4 provides power for the entire tractor to ensure the normal operation of the motor and the switch. The size of the battery 4 is smaller than the size of the handle 1, making the entire tractor more compact and convenient for users to carry and use.

[0042] In terms of the fixed installation of the tractor body 2, it is connected to the handle grip 1 through the rear connection end 3, and connected to the fixing sleeve 7 through the front connection end 6. Such a design enables the tractor body 2 to be stably fixed on the handle grip 1, ensuring the overall stability and durability of the tractor.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
