A garden tool with a plurality of lithium battery boxes

Abstract

The invention provides a garden tool with a plurality of lithium battery boxes. A mower with two lithium battery boxes is produced according to market requirements. While a power source is enlarged, balance weight is added to the front portion of the mower. An internal connecting structure of each lithium battery box is characterized in that twenty internally-mounted lithium batteries have no large-current wires liable to heating therebetween, and multiple connecting plates including six lithium battery anode connecting plates and seventh-eleventh lithium battery cathode connecting plates are connected with a lithium battery socket on the outside of the lithium batteries, so that durable and reliable lithium battery boxes with orderly arrangement are formed. Press joint contacts of the internal connecting structure of each lithium battery box are provided with grooves; each groove is characterized in that one straight groove connects two symmetrical arc-shaped grooves to form two protrusions and each of the two protrusions is provided with two through holes, and thus a press joint contact is formed; the material for the connecting plates is elastic plates subjected to normalizing heat treatment or titanium memory alloy; the overhead view projection of a connecting shaft of two front wheels of the front portion of the mower is provided with at least one lithium battery box.

Description

technical field [0001] The invention relates to a lawn mower used for mowing lawns in courtyards, parks, roadsides and other places. It is a garden tool with a plurality of lithium battery boxes. The power supply is increased and the counterweight is increased. It is a modification of the logarithmic helical brake with automatic lock-up protection and the series-excited motor electric lawn mower with a chassis anti-collision safety belt function wave disc brake, which includes a logarithmic helical brake that can stop automatically A multifunctional lawnmower with a mowing head and a hose reel for liquid lines for watering, fertilizing and spraying. Background technique [0002] Lawn mowers are widely used to mow grass in the manner chosen by people. When some pedestrians like and are used to using lawn mowers, they put a little more force on the rear upper armrest and have a feeling of leaning and pressing down, which virtually increases the possibility of the front wheels...

AI Technical Summary

Problems solved by technology

Anti-collision security and secure braking, mowing and mowing are optional, and there are wires and a large area. These are easier said than done, and they have always been a long-standing problem with electric lawn mowers.

[0006] Why use a cord reel? Because of the long wires scattered on the ground, when the electric lawn mower mows back and forth, sometimes it is accidentally stepped on by feet or crushed by wheels, which affects safety; If the wire is not long enough, mowing is suspended, or the wire is managed manually, which increases safety hazards

Why put a cord reel on an electric lawn mower? Anyone who has used an electric lawn mower knows that weeds often leak when mowing, and they have to be re-mowed. Especially when the environment is complex, such as bushes mixed with the lawn, it is necessary to take several steps forward and several times and repeat the mowing from left to right. Grass; if the reel is placed far away, the wires near the lawn mower cannot be pulled in and out synchronously with the pull and stop in time, or they will fall to the ground limply, and there is a danger of being stepped on or crushed by wheels, or they cannot be pulled in and out in time.
