Problems solved by technology

Some walkers like and are used to using the lawn mower, especially when they encounter corners, press the rotary button in the middle, then turn the main rod 180 degrees, let go, and return to the spring, it can work; but , the main rod often cannot be fixed when it should be positioned, and it swings slightly
The height of the walker is different, and the working angle is different. It is necessary to adjust the length of the main rod. However, the original riveting mechanism for the circular rod used to position the main rod has the disadvantage of easily causing the main rod to shake slightly.

Embodiment Construction

[0128] The operation walker selects the mower by liking and habit, wears protective glasses 32, and also needs to be enclosed within the middle part of the shoulder and the handle with the shoulder strap 33, and selects the line according to the grass situation, or gets the spare nylon thread 34, so that the grass is mowed Connect the power supply and the power cord 1 with the extension cord 35, then adjust the length of the telescopic tube 13-3 according to the height of the walker in operation, and the working angle used to adjust the length of the telescopic tube 13-3, and put the power cord 1 from the said crossing gap 3-2b Fold and pass, then hang on the line hook; hold the auxiliary handle 16 with one hand, hold the handle with the other hand, and push the safety push button 11 and hold the switch trigger 4, Just make the motor drive the mowing line, or use the spare nylon thread 34 to mow the grass.

[0129] The following will explain in detail:

[0130] Because of the...

Abstract

The invention discloses a garden machine with a lithium battery status display unit circuit. The machine comprises a battery status display unit: through taking four LEDs as display devices and performing a status combination, the machine can correctly display a battery voltage, electricity quantity and temperature, and conditions that whether a battery is abnormal, the working status of the battery can be judged according to the above display as plain as daylight. A voltage provided for lithium battery charging uses a multi-harmonic superimposed voltage instead of a voltage for conventional constant-voltage constant-current direct current charging, charging is performed by enabling the multi-harmonic superimposed voltage, which is produced by a multi-harmonic superimposed voltage unit circuit and obtained by mixing of a rectified voltage of a lithium battery charging circuit and a pulse voltage derived from a self-excited multivibrator, to pass through holes for storing electric charges in the lithium battery in a multipoint-acupuncture-liked manner, wherein the pulse voltage is 99V, and the pulse frequency is 99kHz; and the rectified voltage matches the pulse voltage by a differentiating circuit composed of a capacitor and a shunt resistor which are in series.

Description

technical field [0001] The present invention relates to an electric mowing and shrub mowing machine for mowing lawns in places such as flower beds, gardens, parks and roadsides, especially an improvement of a low-vibration dual-purpose machine, which includes a telescopic and adjustable length-adjustable main rod in the upper part of the main machine. Rod, 180-degree rotating bracket, and circuit plus insurance, motor with vibration-reducing foam, double-action switch positioning slide improvement, and a garden machine with improved motor coaxiality and a lithium battery status display unit circuit. Background technique [0002] Lawnmowers are widely used to mow grass in the manner chosen by people's preferences. Some walkers like and are used to using the mower, especially when they encounter corners, press the rotation button in the middle, then turn the main rod 180 degrees, let go, and return to the spring, it can work; but , the main rod often cannot be fixed when it s...
