[0024] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0025] like Figure 1-5 As shown, the handle of the handheld lithium-electric grass trimmer disclosed in the present invention may include: a telescopic rod mechanism, a handle body 10 and a connecting mechanism and other components;

[0026] like Figure 1-5 As shown, the telescopic rod mechanism includes a main rod 1, a receiving slot 2, a positioning hole 3, a slide seat 4, a cavity 5, a limit plate 6, a spring 7, a clamping block 8, and a secondary rod 9;

[0027] The receiving groove 2 is provided inside the main rod 1, two positioning holes 3 are provided on the side of the main rod 1 and are connected with the receiving groove 2, the slide seat 4 is slidably arranged in the receiving groove 2 and is located directly below one of the positioning holes 3, the cavity 5 is provided in the slide seat 4, the limit plate 6 is slidably arranged in the cavity 5, two springs 7 are arranged in the cavity 5 and are located below the limit plate 6, the clamping block 8 is installed on the upper surface of the limit plate 6 and extends to the positioning hole 3 directly above, and the auxiliary rod 9 is installed on the side of the slide seat 4 and extends to the outside of the main rod 1;

[0028] When the telescopic rod mechanism is retracted, the card block 8 is pressed inward to disengage the inserted positioning hole 3 and enter the cavity 5. The descending card block 8 will compress the spring 7 through the limit plate 6. When the card block 8 is disengaged from the positioning hole 3, the fixation of the slide seat 4 can be released. Then, the auxiliary rod 9 is pushed toward the main rod 1 to slowly enter the receiving groove 2, and at the same time, the slide seat 4 is driven to slide in the receiving groove 2. The card block 8 is limited by the inner wall of the receiving groove 2. When the card block 8 is aligned with another positioning hole 3, there is no squeezing of the inner wall to allow the spring 7 to rebound and drive the card block 8 to be inserted into the positioning hole 3, thereby fixing the slide seat 4. The contraction is completed. When unfolding, the card block 8 is pressed inward to release the fixation of the slide seat 4 through the above operation. Then, the auxiliary rod 9 is pulled outward to slowly move it out of the main rod 1 until the card block 8 is stuck in the positioning hole 3. The unfolding is completed.

[0029] like Figure 1-5 As shown, the connection mechanism includes a connection member 11, an external thread 12, and a threaded hole 13;

[0030] The external thread 12 is provided on the side of the auxiliary rod 9, the connecting piece 11 is sleeved on the end of the auxiliary rod 9 provided with the external thread 12, the side of the threaded hole 13 is provided with a threaded hole 13 adapted to the external thread 12, and the handle body 10 is installed on the end of the connecting piece 11;

[0031] The handle body 10 is used for the user to hold and operate the machine. When disassembling the telescopic rod mechanism from the handle body 10, it is only necessary to rotate the handle body 10 to separate the connecting piece 11 from the external thread 12 of the auxiliary rod 9. When merging, the connecting piece 11 can be screwed back onto the external thread 12 on the auxiliary rod 9.
