To achieve the goals above, the technical solution of the utility model is:
One kind preventing electric tool out of supply, it includes, shell and drill bit, and the gear to drive drill bit is equipped in shell
Case, gear-box are controlled by varying speed switch, and gear-box includes:
Guide chute；
Locating piece is installed in guide chute, and the length and width of locating piece is respectively less than the length and width of guide chute
Degree, one end and constitute deep gouge between the guide chute wall of one side that locating piece is not contacted with guide chute；
Such as preceding varying speed switch further include:
Double speed dialing spring, is slidably installed between guide chute and locating piece, can when it slides and falls into deep gouge
Realize the locking of gear.
As preferably, one end of double speed dialing spring passes through guide chute and abuts with the movable tooth circle in gear-box.
As preferably, the length of deep gouge and the internal diameter of double speed dialing spring are isometric.
As preferably, locating piece rounding angle at one end of deep gouge.
As preferably, guide chute is at least two, and is relatively arranged on the two sides of gear-box.
Compared with the prior art, the advantages of the utility model are:
The locating piece for offering guide chute on gear-box and being installed in the guide chute, locating piece and close one
Deep gouge is constituted between the guide chute wall of side, varying speed switch is connect with double speed dialing spring, and one end of double speed dialing spring passes through guide chute extremely
It is abutted in gear-box and with the movable tooth circle in gear-box, double speed dialing spring lock is realized in clamping after double speed dialing spring is fallen into deep gouge after shift
Tightly, double speed dialing spring when preventing using electric tool is detached from preset gear, and stability is good, reasonable in design.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the portion the A enlarged structure schematic diagram of the utility model.
It is as shown in the figure:
1 shell, 2 drill bits, 3 gear-boxes, 4 guide chutes, 5 locating slots, 6 double speed dialing springs, 7 switches, 8 deep gouges.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
As depicted in figs. 1 and 2, one kind preventing electric tool out of supply, it includes, and shell 1 and drill bit 2, drill bit 2 are installed on shell
On body 1, the gear-box 4 to drive drill bit 3 is installed in shell 2, gear-box 3 is controlled by varying speed switch 7, opened by speed change
The sliding of pass 7 carries out gear and adjusts to control drill bit 2,
Wherein, guide chute 4 is offered on gear-box 3, varying speed switch 7 as the aforementioned includes: double speed dialing spring 6.
Specifically, the interior outer end face of guide chute 4 and gear-box 3 penetrates through, locating piece 5 is installed in guide chute 4, is positioned
The length and width of block 5 are respectively less than the length and width of guide chute 4, i.e. one end of locating piece 5 is connect separately with 4 wall of guide chute
One end does not contact then with 4 wall of guide chute, so that constituting between one end of locating piece 5 and 4 wall of guide chute of close one side
Deep gouge 8.
Wherein, the length of deep gouge 8 and the internal diameter of double speed dialing spring 6 are isometric.
Double speed dialing spring 6 as the aforementioned is slidably installed between guide chute 4 and locating piece 5, and double speed dialing spring 6 can be along
Guide chute 4 slides, when it slides and falls into deep gouge 8 as the aforementioned, it can be achieved that the locking of gear, due to the length of deep gouge 8
Degree is isometric with the internal diameter of double speed dialing spring 6, therefore can preferably guarantee that double speed dialing spring 6 without departing from preset gear, is prevented in electronic work
Stop suddenly when tool operation, varying speed switch 7 is installed on shell 1 and connect with one end of double speed dialing spring 6, stirs varying speed switch 7
The sliding of controllable double speed dialing spring 6.
Wherein, one end of double speed dialing spring 6 passes through guide chute 4 and abuts with the movable tooth circle in gear-box 3, double speed dialing spring 6
The mobile switching for realizing gear of the gear in gear-box 3 can be driven when sliding.
Wherein, guide chute 4 is two, and is relatively arranged on the two sides of gear-box 3, each guide chute 4 as the aforementioned
On be mounted on locating piece 5, and double speed dialing spring 6 is slidably installed in guide chute 4, stirs the same time control of varying speed switch 7
Two sides double speed dialing spring 6 processed slides so that shift more easily improves shift efficiency.
As shown in Fig. 2, preferably, locating piece 5 further increases double when gear is adjusted close to one end rounding angle of deep gouge 8
The stability of fast dialing spring 6.
As depicted in figs. 1 and 2, specifically, stirring varying speed switch 7 when carrying out gear adjusting and making double speed dialing spring 6 along guiding
Sliding slot 4 is mobile to deep gouge 8, and double speed dialing spring 6 drives the movable tooth circle abutted with it mobile in sliding, and double speed dialing spring 6 falls into deep gouge 8
In after clamping, realize the locking of gear, double speed dialing spring 6 when preventing using electric tool is detached from preset gear；To carry out shelves
Position readjustment only need to back stir varying speed switch 7, since locating piece 5 is close to one end rounding angle of deep gouge 8, so that double speed dialing spring 6
Slide the more laborsaving stability for also improving gear and adjusting.
The description of the embodiments and the specification only illustrate the principle of the present utility model and most preferred embodiment, is not taking off
Under the premise of from the spirit and scope of the utility model, the utility model also has various changes and improvements, these changes and improvements
It falls within the scope of the claimed invention.
