[0007] The angle adjustment assembly includes a first hinge, a second hinge, and a butterfly handle bolt, which are fixedly threaded together by the butterfly handle bolt.
[0008] The first hinge component includes a first connecting tube and a triangular first hinge seat, which are integrally formed and connected; the first hinge seat includes a first hinge hole that matches the butterfly handle bolt and a circular positioning groove disposed on the hinge surface; the first hinge hole and the positioning groove are concentric; one end of the first connecting tube is fixedly connected to the first connecting rod, and the other end is fixedly connected to the second connecting rod.
[0009] The second hinge component includes a second connecting tube and a triangular second hinge seat, which are integrally formed and connected; the second hinge seat includes a second hinge hole that matches the butterfly handle bolt and an annular positioning protrusion that matches the positioning groove on the hinge surface; the second hinge hole and the positioning protrusion are concentric; the second connecting tube is fixedly connected to the third connecting rod; the positioning protrusion and the positioning groove are mutually limiting and abutting.
[0010] During operation, simply loosen and tighten the butterfly handle bolt on the angle adjustment assembly manually to adjust the angle between the second and third handles to a suitable position for the user, thereby improving the efficiency of mowing.
[0011] Preferably, the hinge surface of the first hinge seat is provided with a first anti-slip pattern distributed along the circumference of the first hinge hole; the hinge surface of the second hinge seat is provided with a second anti-slip pattern distributed along the circumference of the second hinge hole; the first anti-slip pattern and the second anti-slip pattern abut against each other, increasing the connection stability and reliability of the two.
[0012] Preferably, the left and right handles are of the same model and specifications, which has good versatility and reduces production and maintenance costs.
[0013] Preferably, the left handle includes a handle portion and a locking portion, which are integrally connected; the handle portion includes a handle and a socket fixedly mounted on the handle, the socket being slidably fitted onto the third link; the locking portion includes a semi-cylindrical connecting portion and an external lock; the connecting portion and the socket are integrally formed and connected; the external lock is lockably fitted onto the third link, allowing the left and right handles on the link to slide to a reasonable and comfortable position matching the user's body shape and arm length according to the user's habits, and the left and right handles can be rotated to the user's desired angle, improving work efficiency.

[0015] Compared with the prior art, the lithium-ion battery lawnmower of this application has the following advantages:
[0016] 1. Multi-dimensional adjustable ergonomic design: Through the cooperation of the butterfly handle bolt and the positioning protrusion / groove in the angle adjustment component, users can quickly adjust the angle between the second and third links to adapt to different working scenarios and user postures. At the same time, the sliding sleeve and external locking function of the left and right handles on the links support the adjustment of the grip position and rotation angle according to arm length and body size, effectively reducing fatigue during long-term operation and improving operating comfort.
[0017] 2. Stable and anti-loosening structural design: The hinge surfaces of the first hinge seat and the second hinge seat are provided with interlocking first and second anti-slip patterns. Combined with the limiting mechanism of the positioning protrusion embedded in the positioning groove, multiple anti-slip locking is formed after the butterfly bolt is tightened to ensure the long-term stability of the angle adjustment.
[0018] 3. Modular and universal optimization: The left and right handles adopt the same model and specifications to reduce production and maintenance costs; the anti-slip layer (such as rubber or silicone material) on the inner wall of the locking part increases the coefficient of friction to achieve stepless locking.
[0019] 4. Lightweight and Structural Reliability: Both the first and second hinge components are manufactured using a one-piece molding process, reducing weak points in welding or assembly. This ensures connection strength while reducing overall weight, making it easier to handle and carry with one hand. Furthermore, the lithium battery and mowing head are distributed along the main connecting rod axis, optimizing the center of gravity and improving handling balance.
[0020] This invention solves the core problem of poor applicability of traditional integrated handheld lawnmowers through an innovative adjustable handle system and angle locking mechanism. It balances efficient operation with user experience, and is especially suitable for the fine lawn mowing needs in complex scenarios such as home yards and slopes. It significantly improves the ease of use, adaptability and operational stability of handheld lawnmowers. Attached Figure Description
