Description
Technical field
The utility model is related to electric hammer more particularly to a kind of dual-purpose transmission gears of billy club start and stop.
Background technology
Electricity consumption class tool, electric hammer are one kind in electric drill, are mainly used to drill on concrete, floor, brick wall and stone material.
Profession is in metope, concrete, is punched above stone material, also multifunctional electric hammer, adjusts to appropriate location and mixes appropriate drill bit
Common electric drill can be replaced, electric pick uses.
Electric hammer is on the basis of electric drill, a piston for having crankshaft-link rod by motor drive is increased, in a vapour
Reciprocating air in cylinder, making cylinder inner air pressure, the air pressure of variation drives the block stamp in cylinder past in mechanical periodicity
Strike-on hits the top of drill bit.Also there are electric pick and the dual-purpose machine of electric hammer in the prior art, being needed when being used using electric pick will transmission
Tooth is detached from.In the prior art generally use as the mode of Fig. 1 carry out dial be detached from, including driving cog, start and stop dial gear groove
With dentation lasso, gear groove is dialled in start and stop and dentation lasso is integrally formed, and dentation lasso is stirred by dialling catch when dial gear
Driving cog is detached with the gear driven, realization, which stops operating, carries out electric pick percussion operation, and this structure is using integrally formed
Mode needs embryo material big, and processes and need to be ground more, and cost is higher.Further, since the inside of dentation lasso is with dialling catch
Using plane or the mode of arc surface, be easy to cause does not have engagement force hair during use is carried out in the place of contact
Raw electric pick flat chisel angular turn, so as to influence to work as the use of electric pick as electric hammer, working efficiency is low.
Utility model content
In view of the drawbacks of the prior art and insufficient, the purpose of this utility model is to provide one kind can prevent flat chisel from making
It is moved with process transfer, the dual-purpose transmission gear of billy club start and stop that processing cost is low, efficient.
To achieve the above object, the technical solution adopted in the utility model is：A kind of dual-purpose transmission gear of billy club start and stop,
Innovative point is：Gear groove and dentation lasso are dialled including driving cog, start and stop, the start and stop dial gear groove and are located at driving cog and dentation
Between lasso, the side that the dentation lasso dials gear groove close to start and stop is provided with locking tooth lasso, the locking tooth lasso with
Dentation lasso is integrally formed.
Further, gear groove is dialled in the start and stop and dentation lasso is attached by the way of split type connection, described
Start and stop are dialled gear groove and are set in dentation lasso, and the start and stop dial gear groove and dentation lasso by way of being interference fitted and connecting
It is attached.
Further, the driving cog is straight bevel gear.
Preferably, the driving cog is spiral bevel gear.
Preferably, the locking tooth lasso bores tooth lasso for straight-tooth.
Preferably, the locking tooth lasso is curved-tooth bevel gear lasso.
With the above structure, the utility model has the beneficial effect that：
The utility model is being carried out by being provided with locking tooth lasso close to the side of start and stop group gear groove in dentation lasso
After driving cog is made to be detached from transmission when dialling gear, group catch is enabled to resist dentation lasso, so that the pivoted housing of electric hammer will not be sent out
Raw rotation, facilitates electric pick flat chisel to use；And it using split structure, is only needed when being processed smaller using two pieces
Embryo material is processed, and without the raw material using bulk, and processing needs the amount of turning few, cost-effective.
Description of the drawings
Fig. 1 is a kind of schematic diagram of electric hammer start and stop transmission gear in background technology in the utility model；
Fig. 2 is the overall structure diagram in the utility model；
Fig. 3 is the structure diagram during the use in the utility model.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, the present invention is further described in detail.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
Embodiment 1
Referring to Fig. 2, this specific embodiment discloses a kind of dual-purpose transmission gear of billy club start and stop, is dialled including driving cog 1, start and stop
Groove 2 and dentation lasso 3 are kept off, the start and stop dial gear groove 2 between driving cog 1 and dentation lasso 3, the dentation lasso 3
The side that gear groove 2 is dialled close to start and stop is provided with locking tooth lasso 31, the locking tooth lasso 31 and 3 one of dentation lasso into
Type.It is feasible, in this embodiment start and stop dial gear groove 2 and dentation lasso 3 can by integrally formed mode, wherein
The straight-conical teeth quantity of locking tooth lasso 31 can be provided with more.In the present embodiment, consolidated by straight-conical teeth 31 with dialling catch
Determine relative position, pivoted housing can be lockked during electric pick use, so as to prevent flat chisel from rotating in use.
Embodiment 2
Referring to Fig. 3, this specific embodiment discloses a kind of dual-purpose transmission gear of billy club start and stop, is dialled including driving cog 1, start and stop
Groove 2 and dentation lasso 3 are kept off, the start and stop dial gear groove 2 between driving cog 1 and dentation lasso 3, the dentation lasso 3
The side of close start and stop group gear groove 2 is provided with locking tooth lasso 31, and gear groove 2 is dialled in the start and stop and dentation lasso 3 is used and divided
The mode of body formula connection is attached, and the start and stop are dialled gear groove 2 and are set in dentation lasso 3, and gear 2 He of groove is dialled in the start and stop
Dentation lasso 3 is attached by way of being interference fitted and connecting.Using split structure, only need to adopt when being processed
It is processed with two pieces of smaller embryo materials, without the raw material using bulk, and it is few to process the amount for needing to be ground, and saves into
This.It equally can be by being provided with lock close to the side of start and stop group gear groove in dentation lasso by way of being interference fitted and connecting
