Description
Technical field
The screwdriver that the utility model uses when belonging to assembling screw in a kind of electric, machinery manufacturing industry, particularly a kind of improved magnetic set screw cutter.
Background technology
In electric, plant equipment manufacturing, installation, maintenance process, a large amount of screws need assemble, compress, screw can divide according to its head construction serves as reasons: tack is (after locking, the top flushes with work package), the salad head, round end, the circle homalocephalus, the great circle homalocephalus, turret head. etc., because the structure difference of its head, the difference of screw mandrel length, cause screw when mounted, common bottle opener (screwdriver) can only could use screwdriver to carry out reinforcing, screw after the screw screw mandrel correctly vertically inserts nut bore.Though existing in the market magnetic screw driver can be alleviated the screw synchronization implementation to a certain extent and correctly insert nut and carry out reinforcing, screw, but its whole structure is relatively poor, can not always guarantee the concentricity line states of screw and screwdriver preferably, also just can not reach universalness, practicability far away, the function singleness of this magnetic screw driver does not have electrical verification voice, flash of light alarm function in addition.
Summary of the invention
The utility model aims to provide a kind of magnetic set screw cutter, it have simple in structure, cost is low, simple installation, suit in multiple occasion handling characteristics, has electrical verification voice, flash of light alarm function.
The technical solution of the utility model is: connected to form by magnetic knife bar and insulated handle, it is characterized in that: retractable guard and fixed sheath intussusception fit together and are enclosed within outside the knife bar, the spring that will push away before the retractable guard is housed in the fixed sheath, fixedly connected with knife bar in the rear end of fixed sheath, the edge of a knife of knife bar is positioned within the front port that retractable guard stretches out state.
In the cavity of described insulated handle battery is housed, the front end face of insulated handle is equipped with the LED lamp, and battery is connected with lighting button by lead with the LED lamp.
Induction type voltage detecting circuit, speech player and stroboscopic controller also are housed in the cavity of described insulated handle, the built-in battery of insulated handle is powered to speech player and stroboscopic controller, the output of voltage detecting circuit is connected in speech player and stroboscopic controller by the function switch on the insulated handle, and the stroboscopic controller is also connecting the LED lamp.
Described speech player is to be connected to form by circuits for triggering, audio record circuit, voice driven circuit, power amplifier and loudspeaker, the output of power amplifier also is connected with the stroboscopic control circuit of stroboscopic controller simultaneously, insulated handle is provided with the charging jack, and the insulated handle correspondence is built-in with charging circuit.
Insulated handle is provided with charging indicator light, lighting pilot lamp and electrical verification indicator lamp; Loudspeaker over against the insulated handle distal end faces offer the sound pilot hole; Adopt screw thread to fixedly connected between the rear end of fixed sheath and the knife bar.
When using this magnetic set screw cutter, the magnetic knife bar can adsorb screw, simultaneously because the tube wall of retractable guard has entangled nut, form 360 ° of sockets, guarantee that screw is in erectility all the time, when screw carries out crimping, screw-in along with the screw screw mandrel, retractable guard is subjected to fastened stopping and causes retractable guard and spring to shrink, nut is realized separating with retractable guard, the rotary screw cutter, firm until the complete crimping of screw, thus realize the fixing synchronously of normal screws, locate, screw, substrate hold-down function.When energized conductor is carried out the screw crimping, can be converted to the electrical verification state by function switch, knife bar can send phonetic warning when the electrical body, as " having electricity dangerous; to please note safety, careful operation ", the LED lamp sends the high light line flicker of going forward side by side simultaneously, operating personnel are carried out visual alarm, guarantee the personal safety of operating personnel in operating process.When pushing lighting button, the front end face of insulated handle is equipped with the LED lamp to be lighted, and can be working face lighting source is provided.
The beneficial effects of the utility model are: the utlity model has volume small and exquisite, can adapt to the different screw of multiple head, accurate positioning, can flash simultaneously signal, phonetic warning can be widely used in work such as electric, plant equipment manufacturing, installation, maintenance.Screw installs and fixes and prevents screw skew, crooked in electric, plant equipment manufacturing, installation, maintenance process, keeps screw perpendicular to screw and screw, and guarantees operating personnel's personal safety simultaneously.
