Abstract
The utility model discloses a kind of Lead screw transmission structure of electric shrub and hedge trimmer, ball-screw and feed screw nut including bolt, ball is provided with the thread groove of ball-screw, the rearward end of ball-screw is provided with the thrust bearing down moved for limiting ball, feature is that the leading section of ball-screw sets the banking stop that restricted ball up moves, and the diameter of banking stop is more than the internal diameter of thread groove and less than the external diameter of thread groove；Advantage is effectively to prevent ball from, because misoperation screws out, the use of ball is effectively protected, so as to reduce the maintenance cost of user.
Description
Technical field
A kind of electric shrub and hedge trimmer is the utility model is related to, more particularly, to a kind of Lead screw transmission structure of electric shrub and hedge trimmer.
Background technology
Electric shrub and hedge trimmer is the common tool for trimming various branches in gardens.In Patent No. 201510072074.0
State's patent of invention discloses a kind of electric pruner, and it includes scissors body, and the front end of the scissors body is provided with activity even
The cutting blade and ledger-plate connect；The tail end of the scissors body is connected with shell；It is provided with the shell and promotes the cutting blade
The drive device of operation；The bottom of the shell is provided with trigger；The drive device includes motor, epicyclic gearbox, gear train
And power module；Described motor one end is electrically connected with the power module, and the other end is mutually driven with the epicyclic gearbox；It is described
Epicyclic gearbox is mutually driven with the gear train, using electric pruner of the present invention, has that transmission energy is big, noise
Small, blade is readily replaceable, service life into the characteristics of.But the leading screw front end of the Lead screw transmission structure of this kind of electric pruner
Portion does not have a ball protection structure, and user is in maintenance or dismounting easily by the ball particle in Lead screw transmission structure from silk
Thick stick front end screws out, and ball would become hard to be assembled back again, be not easy to make once screwing out in the case of no specialized maintenance instrument
User uses, and adds maintenance cost.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of electric shrub and hedge trimmer for effectively preventing ball from screwing out
Lead screw transmission structure, maintenance cost is effectively reduced, be easy to user to use.
Technical scheme is used by the utility model solves above-mentioned technical problem：A kind of lead screw transmission of electric shrub and hedge trimmer
Structure, include the ball-screw and feed screw nut of bolt, ball is provided with the thread groove of described ball-screw, it is described
The rearward end of ball-screw is provided with the thrust bearing down moved for limiting described ball, before described ball-screw
The banking stop that the restricted described ball of end set up moves, the diameter of described banking stop are more than described thread groove
Internal diameter and the external diameter for being less than described thread groove.
It is of the present utility model further preferably scheme be：The leading section of described ball-screw offers banking stop assembling
Groove, described banking stop are set in described fitting recess and locked by jump ring, convenient disassembly.
It is of the present utility model further preferably scheme be：The central diameter of the diameter of described banking stop and described thread groove is big
It is small equal, it is easy to assemble.
Compared with prior art, the utility model has the advantage of the rearward end of ball-screw to be provided with for limiting ball
The thrust bearing down moved, the leading section of ball-screw set the banking stop that restricted ball up moves, effectively prevent from rolling
Pearl effectively protects the use of ball, so as to reduce the maintenance cost of user because misoperation screws out.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the partial structural diagram of Lead screw transmission structure in the utility model；
Fig. 3 is the structural representation of banking stop in the utility model；
Fig. 4 is the structural representation of jump ring in the utility model；
Fig. 5 is the partial enlarged drawing at A in Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As illustrated, a kind of Lead screw transmission structure of electric shrub and hedge trimmer, include the ball-screw 1 and feed screw nut of bolt
2, ball 3 is provided with the thread groove 11 of ball-screw 1, the rearward end of ball-screw 1 is provided with down transports for limiting ball 3
Dynamic thrust bearing 4, the leading section of ball-screw 1 set the banking stop 5 that restricted ball 3 up moves, the diameter of banking stop 5
Equal in magnitude with the central diameter of thread groove 11, the leading section of ball-screw 1 offers banking stop fitting recess 12, and banking stop 5 is set in
Locked in fitting recess 11 and by jump ring 6.
In above-described embodiment, the diameter of banking stop can be changed according to the actual requirements, the diameter of banking stop 5 need to only expire
Foot is more than the internal diameter of thread groove 11 and less than the external diameter of thread groove 11.
A kind of Lead screw transmission structure of electric shrub and hedge trimmer provided by the utility model is described in detail above, this
Apply specific case in text to be set forth principle of the present utility model and embodiment, the explanation of above example is
It is used to help understand the utility model and core concept.It should be pointed out that for those skilled in the art,
On the premise of not departing from the utility model principle, some improvement and modification can also be carried out to the utility model, these improve and
Modification is also fallen into the protection domain of the utility model claims.
