Description
Technical field
The utility model relates to a kind of adjustable speed electric drill.
Background technology
The speed governing electric drill generally has a mechanical speed governors mechanism, and for improving the comfortableness of speed governing, the ratio that the speed switching handle of common mechanical speed governors mechanism can design is higher, exposes to the top of electric drill casing.Speed switching handle is positioned at electric drill casing top and can produces following two common problems: first, when needs carry out the speed switching, must finish jointly by two hands of operator, a hand is used to hold electric drill, the another hand operated is positioned at the speed switching handle at electric drill casing top, often operating personnel's another hand need carry out hand by operations such as screws, will influence operation like this, makes operation more complicated; The second, because speed is switched the restriction of handle height, and the distance between the palp barrier of the output of electric drill and drill body is strengthened, so the working region of electric drill has been reduced, and makes the scope of application of electric drill dwindle.
The utility model content
Technical problem to be solved in the utility model is: at the shortcoming of above prior art existence, a kind of adjustable speed electric drill is proposed, can the speed governing of handled easily personnel one-handed performance, and reduced the distance of machine top and barrier, increased the scope of application of electric drill in small space.
The technical scheme that the utility model solves above technical problem is:
A kind of adjustable speed electric drill, it comprises; Casing has a grip portions; Motor is located in casing; Reducing gear, in casing the location and by motor-driven; Speed adjusting gear comprises a handle that speed is switched that is used for that exposes to casing at least, the execution member that the inner gear ring of drive reducing gear is done to move the position; Output mechanism is installed in outside the casing and by reducing gear and applies the rotation of slowing down; The handle that is used for the speed switching in the speed adjusting gear is positioned at the two sides of casing.
Because the handle that speed is switched is positioned at the two sides of casing, operating personnel only need one-handed performance can realize speed governing; In addition, speed is switched handle and is not had limitation in height, and the distance between the palp barrier of the output of electric drill and drill body is reduced, so the working region of electric drill has been strengthened.
This shows that the utility model is scientific and reasonable switches speed the two sides that handle places casing, a little position changes can solve two technical problems that " bimanualness " reaches " working region is reduced ", kills two birds with one stone.
The technical scheme that the utility model further limits is:
Aforesaid adjustable speed electric drill, speed switch handle and are positioned near the grip portions of casing side, and the position that thumb can touch when being positioned at operating personnel and holding grip portions.Speed is switched handle and is had a primary importance and a second place of selecting low speed output of selecting output at a high speed.The primary importance and the second place are positioned at the both sides up and down of motor horizontal axis.
Aforesaid adjustable speed electric drill, it is a cylindrical component that speed is switched handle, is enclosed within on the excircle of motor, the axis that centers on motor rotates.
Aforesaid adjustable speed electric drill, speed switch between handle and the described execution member and directly are connected or connect by connector.Connector is wire, bonding jumper or sheet metal.
Aforesaid adjustable speed electric drill, reducing gear is a planetary gear reducing mechanism, comprises that one is installed in the ring gear that can move along the electrical axis direction gear-box inside and one and is installed in the steel wire rack that described internal tooth ring recess is exposed to gear-box at home and abroad; Carry out member and comprise that transmission steel wire and ring gear drive circle, speed is switched handle and is provided with cylindrical hole with the end face that ring gear driving circle is faced mutually, transmission steel wire insertion speed switches handle and ring gear drives in the corresponding cylindrical hole of circle, the two is coupled together, make operator's rotary speed switch handle and can drive the rotation that gear ring drives circle; Ring gear drives circle and is provided with groove in a circumferential direction, and steel wire rack is stuck in the groove, does under the rotation that ring gear drives circle drives along the moving of electrical axis direction, thereby drives moving of ring gear, realizes that the speed ratio of planetary gear reducing mechanism switches.It is a cylindrical component that ring gear drives circle, is enclosed within on the excircle of planetary gear reducing mechanism, and the axis that centers on motor rotates.The transmission steel wire is cylindrical steel wire.
The utility model has the advantages that: the utility model can effectively be realized the switching of electric drill speed, easy to use, and owing to the switching handle of speed adjusting gear has been put into the side of electric drill casing, reduce the distance of machine top and barrier, increased the scope of application of electric drill in small space.

The specific embodiment
Embodiment one
Present embodiment is a kind of adjustable speed electric drill, structure as depicted in figs. 1 and 2, the adjustable speed electric drill comprises casing 1, has the motor 2 of location therein in the casing 1, motor 2 drives same planetary gear reducing mechanism 5 of locating in casing 1, thereby the rotatable output mechanism 7 outside being installed in casing applies the rotation of slowing down.Planetary gear reducing mechanism 5 comprises the ring gear 9 and the steel wire rack 10 that is installed in the above-mentioned internal tooth ring recess, exposes to gear-box that are installed in gear-box inside, can move along the electrical axis direction.
The adjustable speed electric drill comprises a speed adjusting gear 3, and speed adjusting gear 3 comprises that at least one can be from the speed switching handle 11 of casing 1 peripheral operation, and transmission steel wire 4 drives circle 6 with ring gear.
