Abstract
The utility model relates to a handheld speed regulation electric drill, and belongs to the technical field of electric tools. The electric drill is provided with an enclosure of a holding part; a motor is arranged in the enclosure and is in transmission connection with an output mechanism through a reducing mechanism; the reducing mechanism is provided with a shift gear ring which is at least provided with a first gear and a second gear in an axial direction, wherein the first gear and the second gear can realize high-speed working and low-peed working; and the upper rear part of the holding part, which a finger can touch, is provided with a speed gear shift operation piece which is in transmission connection with a drive piece of the shift gear ring through a stripped connection piece. Long-distance operation transfer from the gear shift operation to shift execution is realized; the handheld speed regulation electric drill has a simple structure; connection of a middle transition piece is not needed; the operation piece is positioned on the upper rear part of the holding part, so the operation piece is not touched when the electric drill is placed; and during operation, the electric drill is positioned below human eyes, so the electric drill is convenient to monitor and has good safety performance.
Description
Technical field
The utility model relates to a kind of speed governing electric drill, and especially a kind of hand-held speed governing electric drill belongs to the electric tool technical field.
Background technology
Hand-held speed governing electric drill is a kind of electric tool commonly used, and the speed of its speed adjusting gear is switched the top that handle exposes to the electric drill casing usually.There is following problem in the use: the one, when carrying out the speed switching, must be used to hold electric drill by a hand, the another hand operated is positioned at the speed switching handle at electric drill casing top, and is convenient inadequately; The 2nd, the height of speed switching handle has strengthened the contour dimension of electric drill, has limited the use of electric drill in narrow and small operating space.
Retrieval is found; Application number is that the one Chinese patent application that CN200510121668.2, name are called " a kind of hand held power machine " discloses a kind of hand-held speed governing electric drill, and it has a handgrip, transmission device and at least one of one at least two grades is used for the bridgeware of this transmission device of conversion between different speed change levels.The distance that this bridgeware is set to the hand gripping area that is used to place the operator from handgrip is less than or equal to maximum finger and touches distance.Therefore can realize one-handed performance, and help to reduce the contour dimension of electric drill.
Yet the bridgeware of this electric drill setting need be delivered to the middle driving member of front end by the electric drill rear end with speed governing action through a series of realizations, so transmission link is many, complex structure.In addition, the part of controlling of bridgeware is positioned at the casing side, and security performance is not good enough.
Summary of the invention
The purpose of the utility model is: to the shortcoming of above prior art existence; Proposing the gearshift of a kind of not only speed controls part and is positioned near the scope that finger can touch the holding area; And the very simple and direct hand-held speed governing electric drill of speed gearshift action transmission link, switch thereby realize being hold by one hand and controlling speed.
In order to achieve the above object, the hand-held speed governing electric drill of the utility model comprises: have the casing of holding area, be mounted with motor in the said casing, said motor via reducer structure and output mechanism are in transmission connection; Said reducing gear has the power shift gear ring, and said gear ring has at least to be realized respectively at a high speed and axial first gear and second gear of low speed; Finger can the place of touching be provided with speed and dials retaining and control part near the said holding area, and said speed is dialled to keep off and controlled the actuator of part through strip connector and said power shift gear ring and be in transmission connection.
In the prior art, the executive item of speed gearshift---power shift gear ring is usually located at the electric drill front portion can touch the place away from finger, when speed being dialled retaining and control part and be arranged on the scope that finger can touch, between the two apart from far away.The technique scheme of the utility model rationally utilizes the strip connector to realize that fork shift controls the remote control transmission of gearshift between carrying out; It is simple in structure, need not the linking of middle transition part, and is positioned at the back upper place, holding area owing to control part; Therefore can when placing electric drill, do not touched; Be positioned at the human eye below during operation, be convenient to monitoring, security performance is good.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one.
The specific embodiment
Embodiment one
The hand-held speed governing electric drill of present embodiment is as shown in Figure 1; The profile of casing 1 is pistol-shaped; Has holding area 1-1; Be mounted with motor 2 in the casing on 1-1 top, holding area, the two-stage planet reducing gear of this motor through being arranged in gear-box 2-1 is in transmission connection with drill chuck 3 as output mechanism.Have power shift gear ring 4 in the reducing gear, thereby this gear ring have axial first gear and second gear (this part body and prior art are identical, so do not detail) that leaves, closes realization high speed and low speed respectively with the fixed teeth torus.The 1-1 back upper place, holding area of casing 1 finger can the place of touching be provided with to dial as speed and keeps off the be shifted toggle 5 of controlling part; The front end of this toggle have with strip connector 6 rear ends under the 5-1 of prong up of hook heads 6-1 engagement; The front end of strip connector 6 with hinged in casing 1 upper end as the activation lever 7 of power shift gear ring actuator be connected; The lower end of activation lever 7 is connected with the power shift gear ring, thereby realizes being shifted toggle 5 being in transmission connection through strip connector 6 and activation lever 7.
In the use, when stirring toggle 5 displacements, strip connector 6 will be with and moved forward and backward, and activation lever 7 is swung thereupon, thereby makes power shift gear ring 4 displacement between axial first gear and second gear as required, realizes the switching of high low speed.
Facts have proved that the hand-held speed governing electrodill of present embodiment has following outstanding advantage:
1. the user can carry out high low speed switching by one hand in operation, is convenient to operation, can raise the efficiency.
2. because high low speed handoff functionality is external at the electric drill rear, the user that is more convenient for like this observes in operating process.
The utility model is not limited to the above embodiment, and it is that other similar techniques schemes are all in the protection domain of the utility model that all those skilled in the art need not creative work.
Claims (4)
