Description
Technical field
the present invention relates to a kind of pruning tool, particularly the rotatable pruning tool of a kind of tool section.
Background technology
conventional pruning tool, as pruner, being mainly used in shearing trees, the branch of shrub and blade to reach the object of finishing trees or shrub shape, is the graden machine that a kind of frequency of utilization is higher.In prior art, when the branch needing pruning side etc. not easily to prune, user can only by different postures to adapt to different cutting situations, and comparatively inconvenient during use, operating efficiency reduces.Same, also there is same problem in other pruning tool such as mower.At present, also having some of carrying out for side cutting to improve, is generally realized side cut by electric rotating machine, transmission system, front hand grip, shearing tool section whole system.This set makes the gripping rotating rear front hand grip inconvenient; Rotary system mechanism is many, weight large, and rotary course not easily manipulates; Motor is included in rotary system, and pruning tool center of gravity is forward, front and back hand discontinuity, singlehanded stressedly excessively easily causes rapid fatigue.
Summary of the invention
for the problems referred to above, the invention provides a kind of pruning tool, its tool section rotate convenient, be easy to manipulation.
for solving the problems of the technologies described above, the technical solution used in the present invention is:
a kind of pruning tool, it comprises fore shell, back cover, is arranged at the universal joint between fore shell and back cover, the motor be fixedly installed in back cover, the tool section be arranged in fore shell, output shaft and the transmission of universal joint phase of described motor, described fore shell can rotate relative to back cover under the ordering about of universal joint, and in described fore shell, the driving force be also provided with for being subject to by universal joint is passed to the transmission mechanism of tool section.
preferably, it comprises the locking mechanism for locking fore shell, and described locking mechanism comprises locking piece, is fixedly installed on the banking stop on rotation casing and the button for the action of operable lock locking member.
preferably, the output shaft that described universal joint comprises ball cage and is fixedly connected with described ball cage, described ball cage is set on the output of motor output shaft, described ball cage is along the guide channel circumferentially offering multiple linearly shape of motor output shaft, be provided with multiple guide ball between described guide channel and described motor output shaft, described guide ball can be rolled in described guide channel.
preferably, it also comprises the first in command and the second in command that are arranged at back cover, and when playing first violin with second in command's action simultaneously, the microswitch be arranged in back cover starts, and microswitch passes through control circuit transmission of electric signals to motor.
preferably, described transmission mechanism comprises power transmission shaft, first order reduction gearing, second level reduction gearing and eccentric wheel, described power transmission shaft is with the transmission of universal joint phase and be meshed with described first order reduction gearing, described first order reduction gearing is meshed with described second level reduction gearing, described second level reduction gearing is coaxially connected with described eccentric wheel, and described eccentric wheel is in transmission connection mutually with described tool section.
preferably, the dead in line that rotates relative to described back cover with described fore shell of the axis of the output shaft of described motor.
the present invention adopts above structure, and because rotary system does not comprise handle and motor, rotary system mechanism is few, lightweight, and rotary course more easily manipulates; Because motor is horizontally placed in casing, casing length increases, and also just adds the distance of forward and backward handle, more meets ergonomics, is convenient to grip; Because motor is positioned at casing, make the side skew backward of pruning tool machine gravity, make front and back hand stressed more even, avoid due to the stressed much rapid fatigue caused of one hand.
Accompanying drawing explanation
fig. 1 is the structural representation of a kind of preferred embodiment of the present invention.
fig. 2 is the structural representation of the universal joint of a kind of preferred embodiment of the present invention.
fig. 3 is the sectional view of the universal joint of a kind of preferred embodiment of the present invention.
Embodiment
below in conjunction with accompanying drawing, a kind of preferred embodiment of content of the present invention is elaborated.
with reference to shown in accompanying drawing 1, a kind of pruning tool, it comprises fore shell 2, back cover 1, is arranged at the universal joint 3 between fore shell 2 and back cover 1, the motor 11 be fixedly installed in back cover 1, the tool section 21 be arranged in fore shell 2, output shaft 12 and the transmission of universal joint 3 phase of described motor, described fore shell 2 can rotate relative to back cover 1 under the ordering about of universal joint 3, and in described fore shell 2, the driving force be also provided with for being subject to by universal joint 3 is passed to the transmission mechanism of tool section 21.
it also comprises the locking mechanism for locking fore shell 2, and described locking mechanism comprises locking piece 13 and the button 14 for the action of operable lock locking member.Described button 14 one end is connected with a spring 141, and one end is arranged with latch 142 with spring 141, and fore shell 2 top is fixedly installed one in semiorbicular banking stop 26, banking stop 26 is evenly equipped with several holes.When pulling button 14, spring 141 drives latch 142 to move, and latch 142 promotes locking piece 13 and exits hole on banking stop 26, thus locking piece 13 and fore shell 2 are departed from, and fore shell 2 is in released state, the rotatable tool section of user.When release button 14, the deformation of spring 141 is tried hard to recommend dynamic latch 142 and then is driven locking piece 13 to insert in the hole of banking stop 26, realizes locking.
described locking piece 13 side is provided with guiding rib, described casing is provided with the gathering sill matched with described guiding rib, and described locking piece 13 is stuck in described gathering sill by described guiding rib.
