    Light gardening tool combining several types of different use heads
    Technical area
    The present invention relates to the technical field of gardening tools. It is a light gardening tool combining several types of different uses.
    State of the art
    Depending on the different power types, gardening tools can be divided into two categories, motorized tools and power tools. A power tool is equipped with a two-stroke or four-stroke motor. Its disadvantage is the important weight. Generally, workers use gardening tools to carry out gardening of an area of more than two acres. Operations include cutting lawns, leveling shrubs, treating branches, swelling leaves, etc. A variety of devices is therefore required. A lightweight, multifunctional and easy to move tool can provide gardening workers with better convenience. With existing technologies, when using a gardening tool, you need to bring a longer power cable or a small generator to ensure the power supply. Generally, to convert AC electricity into DC electricity, a converter must still be prepared. All this increases the cost. With these constraints, it is necessary to bring the source of power to carry out the gardening operations in a very far place, especially the conversion of the electricity input into electricity AC.
    detailed description
    The present invention of a light gardening tool is thus designed to solve these problems. The main problem to be solved is to improve the convenience of using gardening tools.
    This problem is solved with this tool: This light gardening tool combining several types of different use heads consists of the main part, the functional heads, the extension tube, the intermediate extension fitting and the intermediate fitting for the functional head; Either the end of the main part is connected with a functional head, or it is connected with the intermediate extension fitting; The end of this intermediate extension fitting is connected with the extension tube, the end of said tube is connected with the intermediate connection for the functional head, and the latter is finally connected with the functional head.
    Said functional head consists of the connection head and the function head. The function heads include the chain saw head, the mower head, the sawhead for shrubs and the inflator head. The connection head is integrated in the function head. Inserts C salient are provided on the connecting heads. These inserts C are to be connected with the connecting grooves of the functional heads. Either the extension insert on the extension part of the main part is connected with the functional head, or it is connected with the functional head after being connected with the intermediate extension fitting. The different types of aforementioned function heads can be used to perform the corresponding functions. In case of operation at medium or longer distance, it is possible to connect the extension tube to the intermediate extension fitting;

This tool is even more suitable for use in a large garden, for lawns, in a hotel or in a botanical garden. Equipped with at least 3 functional heads, with a single tool, different operations can be performed at the same time. With the different combinations of the functional heads and the main part, the part and the intermediate elongation joint, the intermediate extension joint and the extension tube, the functions and method of use of this tool are very varied. . For example, if the functional head is connected directly with the main tool part, the tool can be used directly by hand for short-distance operation; If my extension tube is extended, the tool can be used for long-distance operation; This tool can therefore be used in different environments. 2. The functional head can be extended with the slide provided. Mechanisms such as the safety switch tab are provided for the slide to protect the structure of the main part and the inner circuit in the tube. Replacement is easier. It is only necessary to dismantle the functional head and the connecting device to mount the new functional head. The AC power supply is guaranteed by the battery pack.

In addition, the special LED indicator module is arranged to control and indicate the service status of the entire product. Two-fuse filtering and direct and reverse filtering are provided for the module circuit to achieve double assurance and thus extend the lifetimes of LEDs and the tool, reduce fault rate and stabilize voltage. The storage and distribution of all configuration data is performed by the standalone LED drive unit, the control unit, the single cell sample unit and the memory storage unit. Different configurations can therefore be realized for the circuits of power tools, which adapts to multifunctional gardening tools. The use of the tool is thus much more practical. 3. The downstream compatible voltage regulator is disposed within the main part of the tool, which is suitable for different series of battery packs. This regulator can convert the voltage to guarantee the service of different voltage lithium battery packs in different tools. The controller is connected in parallel between the battery pack and the tool by conductors. The controller can perform voltage increase / decrease (BUCK / BOOST), voltage conversion and power supply to ensure the increase of battery packs, for example 40 series of battery packs. This product can be used for power tools and 5-35 block gardening tools to ensure the universality of battery packs. The equipped transfer device can significantly improve the starting performance of the chain saw, while sparing the strength of users such as women. Three types of fasteners are provided in this technical solution for making different functional heads and couplings connections and two power controls. The sawhead for fitted shrubs can cut out arch-shaped shrubs. Individual blades are also provided to independently perform the operations.
