Embodiment
For the ease of understanding the present invention, the present invention is described more fully below with reference to relevant drawings.In accompanying drawing
Give the preferred embodiment of the present invention.But the present invention can realize in many different forms, however it is not limited to herein
Described embodiment.On the contrary, the purpose for providing these embodiments is to make the understanding to the disclosure more saturating
It is thorough comprehensive.
It should be noted that when element is referred to as " being fixed on " another element, it can be directly on another element
Or there may also be element placed in the middle.When an element is considered as " connection " another element, it can be directly connected to
To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ",
" right side " and similar statement are for illustrative purposes only.
Unless otherwise defined, all of technologies and scientific terms used here by the article is with belonging to technical field of the invention
The implication that technical staff is generally understood that is identical.Term used in the description of the invention herein is intended merely to description tool
The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term as used herein " and/or " include one or more phases
The arbitrary and all combination of the Listed Items of pass.
As shown in Figures 1 and 2, a kind of reciprocating power tool 100 of this preferred embodiment, the reciprocating power tool 10 include
Motor and transmission mechanism 20, motor drives work first 40 to move back and forth by transmission mechanism 20, so as to add to work piece
Work.In the present embodiment, reciprocating power tool 100 is reciprocating saw, it will be understood that in other embodiments, reciprocating power tool
100 can also be other devices such as sweep-saw.
Wherein, transmission mechanism 20 includes reciprocal bar assembly 22, and reciprocal bar assembly 22 includes reciprocating lever 222 and is located at reciprocating lever
Reinforced structure 224 on 222.
Above-mentioned reciprocating power tool 100, because reciprocal bar assembly 22 includes reciprocating lever 222 and reinforced structure 224, therefore it is past
Compound lever 222 can use the less material of density, to avoid the vibrations brought in the course of work because weight is excessive, so as to keep away
Exempt from user using larger vibrations are experienced during reciprocating power tool 100, improve the usage experience of user, and less machine shakes
The dynamic damage to each part.The density of reinforced structure 224 is then more than the density of reciprocating lever 222, therefore is mitigating the same of weight
When ensure that the reciprocal bar assembly 22 has enough rigidity, without bending in the process of running, so as to mitigate weight
It ensure that good stability and service life simultaneously.
Further, the density of reinforcing mechanism 224 is more than the density of reciprocating lever 222, to mitigate reciprocal bar assembly 22
Enough rigidity is ensure that while weight, avoids producing vibrations because weight is excessive in the course of work.
In the present embodiment, reinforced structure 224 is the protective case being sheathed on reciprocating lever 222, and the preferable protective case is
Tubular structure.It is appreciated that the shape of reinforced structure 224 and mounting means not limited to this, can be arranged as required to.
Please continue to refer to Fig. 2, reciprocating lever 222 includes the first reciprocating lever 2222 and the second reciprocating lever 2224 being connected with each other,
Reinforced structure 224 does not coat reciprocating lever 222 located at the second reciprocating lever 2224 completely, so as to while enough rigidity is ensured
Further reduce the weight of the reciprocal bar assembly 22.It is appreciated that reciprocating lever 222 is optionally arranged at, rigidity is smaller or institute
By the region that stress is larger, so as to increase the rigidity of the reciprocating lever 222 as needed, reciprocating lever 222 is avoided to bend or be broken.
Specifically, the diameter of the first reciprocating lever 2222 is more than the diameter of the second reciprocating lever 2224, therefore with larger firm
Degree.The one end of reinforced structure 224 is held in one end that the first reciprocating lever 2222 connects the second reciprocating lever 2224, passes through the first reciprocating lever
2222 and the second step surface between reciprocating lever 2224 carry out spacing, avoid moving to the direction of the first reciprocating lever 2222.
Further, the first reciprocating lever 2222 is integrally formed with second reciprocating lever 2224, so that reciprocating lever 222 has
There is higher intensity, avoid being broken between the first reciprocating lever 2222 and the second reciprocating lever 2224, and facilitate the system of reciprocating lever 222
Make, reduce production process.
In the present embodiment, the material of the first reciprocating lever 2222 and the second reciprocating lever 2224 is the plastic cement of lightweight.Reinforcement
The material of structure 224 is steel.Plastic cement is mainly made up of carbon, oxygen, hydrogen and nitrogen and other organic or inorganic elements, can be heated with machine
Make its fusing, plus-pressure its flowing, cooling is made its solidification, and formed variously-shaped.Because the rigidity of steel is more than plastic cement
Rigidity, therefore by setting reinforced structure 224 made of steel on the reciprocating lever 222 of plastic material, it is ensured that reciprocating lever
222 with enough rigidity while with lighter weight.It is appreciated that the material not limited to this of reciprocating lever 222, can basis
Need to use other materials.First reciprocating lever 2222 can be also molded respectively with the second reciprocating lever 2224, and material also can be different.
Please continue to refer to Fig. 1 and Fig. 2, transmission mechanism 20 also includes rotatable connecting rod 24, and connecting rod 24 can drive reciprocating lever
Axial movement of the component 22 along reinforced structure 224, so as to the axial linear movement by the rotation conversion of connecting rod 24.In this way, motor
Connecting rod 24 can be connected and drive link 24 rotates, and then drive the reciprocal axially reciprocating of bar assembly 22, it is final to drive work head
40 carry out cutting operation.
Further, reciprocating power tool 100 also includes locating part 26, and reciprocating lever 222 is offered along the axle of reinforced structure 224
To the stopper slot 2222a of extension, locating part 26 is located in stopper slot 2222a and can moved back and forth along stopper slot 2222a, so as to limit
Reciprocating lever 222 processed moves back and forth in stopper slot 2222a bearing of trends, changes transmission direction.
Further, reciprocating power tool 100 also includes bearing 28, and the one end of reciprocating lever 222 rotatably connects with connecting rod 24
Connect, the other end is sheathed in bearing 28 and can moved axially with respect to bearing 28.
Above-mentioned reciprocating power tool 100, because reciprocal bar assembly 22 therein is made of the less material of density, therefore
Vibrations during work are smaller, improve Consumer's Experience.Also, due to the lighter in weight of reciprocal bar assembly 22, therefore alleviate whole
Machine weight, facilitate the use and movement of the reciprocating power tool 100.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
Say, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
