Grass-mowing pruning shear

Abstract

The present invention relates to pruning shears which consist of a main frame, a wheel component and a prolonged handle, wherein, the shell of the main frame is provided with a power source, a first micro switch, a motor, a first switch button and a first self-locking push button, which start and stop the motor; the output of the motor drives a shearing mechanism through a gear box and an eccentric mechanism; the shell is also provided with a pair of shell pole pieces, a switch pressing rod and a second micro switch; the bottom of the shell can be disassembly connected with a wheel component that is composed of a base, a wheel seat and a wheel, and a positioning-part pole piece that is arranged on the wheel component is supported against the pole pieces of the shell; the prolonged handle can be disassembly connected with the wheel component at different angles and a fixed-block pole piece on the prolonged handle is supported against the positioning-part pole piece, the fixed-block pole piece is electrically connected with a third micro switch, and the startup of the motor is realized by a second switch button and a second self-locking push button. The design of the present invention has three application modes which can be independently used or used in combinational way according to different usages, thereby enlarging the application range and being convenient to be used; lithium battery is adopted as the power source, thereby, the environment-protection property is good; the shearing mechanism can be mutually exchanged, thereby the present invention has multiple functions; the double safety switches have good safety.

Description

technical field [0001] The invention relates to the technical field of garden machinery, in particular to a grass-cutting pruning shears capable of pruning lawns and branches. Background technique [0002] Grass-cutting pruning shears are portable tools used to trim garden lawns, flowers, fruits and branches. They are an essential tool for people to create a clean and green living environment. Manual shears that were commonly used in the past were eliminated due to laborious, high strength and low efficiency. , has long been replaced by electric pruning shears. There are many varieties of electric pruning shears, usually with a rechargeable battery as the power supply, the double safety switch touches the micro switch to start the motor, and the gear box decelerates and the eccentric mechanism drives the cutting mechanism to realize the trimming of lawns and branches. For example, the patent No. 01257686.7 disclosed in the Chinese patent literature "an electric pruning shea...

AI Technical Summary

Problems solved by technology

For example, the patent No. 01257686.7 disclosed in the Chinese patent literature "an electric pruning shear" and the patent No. 95222327.9 "double-insulated electric pruning shears" are all pruning shears with double safety switches, which provide a guarantee for people's safe operation. , but most of the functions are single, and the operation mode is irreversible

Also have the patent No. 00240748.5 "environmentally friendly multi-purpose lawn mower", this lawn mower is equipped with traveling wheels at the bottom of the frame, and the extension handle that pushes the walking wheels forward, this mechanism is generally used as a lawn mower for pasture harvesting, If the lawn needs to be trimmed, a mowing tool needs to be installed on the rotating shaft protruding downwards. Its extension handle and travel wheels only play the function of promoting the host, and cannot be disassembled. The handle must cooperate with the application, and it cannot meet the different operation modes required by different occasions, and the scope of application is limited
