Improvement structure of shears machine

Abstract

The invention discloses an improvement structure of a shear machine, comprising an enclosure, a motor arranged in the enclosure and a trigger arranged on the enclosure, wherein the motor drives a blade assembly on the front end of the enclosure by a transmission mechanism; the transmission mechanism comprises a master transmission assembly and a slave transmission assembly, wherein the master transmission assembly is connected with the motor, and the slave transmission assembly is connected with the blade assembly; the master transmission assembly and the slave transmission assembly are connected by a torsional spring with helical structure; meanwhile, the torsional spring tightly holds the top of the master transmission assembly and the tail of the slave transmission assembly to realize that the master transmission assembly, the slave transmission assembly and the torsional spring are connected and rotate; the enclosure is also provided with a brake mechanism; the brake mechanism is clamped on the rotation direction of the torsional spring while the torsional spring rotates along with the master transmission assembly to ensure that the torsional spring loosens the master transmission assembly to brake, and the trigger controls the brake mechanism to clamp the torsional spring or not by a connecting mechanism. The invention has the advantages of compact structure, convenient blade replacement and stable output power, greatly improves the shearing torsion of the shear machine and can shear thick twigs.

Description

technical field [0001] The invention relates to a garden tool, in particular to a scissors machine for trimming branches, shrubs and the like. Background technique [0002] Scissors are a commonly used garden tool for trimming branches, shrubs, etc. Compared with traditional manual scissors, using scissors for trimming greatly reduces labor intensity and improves efficiency. Increased, the scissors will become an essential garden tool. However, in practical applications, scissors still have many shortcomings. At present, the rotation and braking of most scissors blades need to be realized by the forward and reverse rotation of the motor, which is inconvenient to operate, consumes a lot of energy, and more importantly, the output power of the motor If it is not effectively utilized, the rotational torque of the blade is reduced, making it impossible for the scissors to trim thicker branches, which limits the scope of use of the scissors. Not only that, but the frequent rotat...

However, in practical applications, scissors still have many shortcomings. At present, the rotation and braking of most scissors blades need to be realized by the forward and reverse rotation of the motor, which is inconvenient to operate, consumes a lot of energy, and more importantly, the output power of the motor If it is not effectively utilized, the rotational torque of the blade is reduced, making it impossible for the scissors to trim thicker branches, which limits the scope of use of the scissors. Not only that, but the frequent rotation direction of the motor will also shorten the life of the motor itself. service life
