Accompanying drawing explanation
Fig. 1 is the structure perspective view of a kind of embodiment of the controlled screwdriver of magnetic force of the present utility model;
Fig. 2 is the structure perspective view of another embodiment of the controlled screwdriver of magnetic force of the present utility model;
Fig. 3 is the part section structural representation of Fig. 2.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment 1: as shown in Figure 1, Figure 2 and Figure 3, the controlled screwdriver of a kind of magnetic force, comprises handle 4 and the knife bar 3 being fixedly connected with handle 4 lower ends 401, and the lower end 302 of knife bar 3 has cutter head 1.On handle 4, have cavity 5, the upper end 301 of knife bar 3 is positioned at cavity 5, is provided with movable permanent magnet 2 in cavity 5.The utility model arranges permanent magnet 2 on handle 4, by permanent magnet 2, realizes the adjustment of screwdriver magnetic force and control with contacting with disengaging of knife bar.Specifically can adopt various ways, as shown in Figure 1, on handle 4, have the cavity 5 adapting with permanent magnet 2, permanent magnet 2 is inserted cavity 5 and is contacted with the upper end 301 of knife bar 3 when interior, because being magnetic conductive metal, existing knife bar 3 and cutter head 1 make, so the magnetic force of permanent magnet 2 can be passed to cutter head 1, realize the absorption to screw.When not needing magnetic force, only permanent magnet 2 need be taken out from cavity 5 permanent magnet 2 and knife bar 3 are departed from.But because permanent magnet 2 in use need to depart from handle, the slightly inconvenience of using.Can adopt following optimal way for this reason.
As above-described embodiment preferably, referring to Fig. 2 and Fig. 3, the axial length of cavity 5 is greater than the length of permanent magnet 2, permanent magnet 2 can move axially along cavity 5.Like this, when permanent magnet 2 moves to while contacting with knife bar 3 along cavity 5, screwdriver produces the magnetic force to screw.When permanent magnet 2 is along cavity 5 during gradually away from knife bar 3, the magnetic force of 1 pair of screw of cutter head weakens gradually until can not adsorb screw.This kind of mode used very convenient.And realize, the control of the position of permanent magnet 2 and adjustment are had to various ways, provide comparatively preferred mode below.
As above-described embodiment preferably, referring to Fig. 2, on handle 4, be provided with vertically and be communicated with the inside and outside chute 6 of cavity 5, chute 6 is provided with sliding part 7, sliding part 7 is connected with permanent magnet 2.By the control realizing the position of permanent magnet 2 at handle 4 outside operation sliding parts 7, simple in structure, easy operating.Do not need other special structures, as long as there is certain frictional force sliding part 7 can be adjusted and be positioned the position needing together with permanent magnet 2 between sliding part 7 and handle 4.A kind of concrete structure is as follows, and sliding part 7 has two relative clamp bar slots, forms two relative slide rails on the handle 4 of chute 6 both sides, and two slide rails are stuck in respectively in two clamp bar slots.Another alternative as sliding part 7 is that permanent magnet 2 is connected with an action bars, and action bars stretches out from the upper end 402 of handle 4, by being pulled outwardly or inwardly promoting action bars, realizes the adjustment to the position of permanent magnet 2.
For the ease of being connected of sliding part 7 or action bars and permanent magnet 2, sliding part 7 or action bars can be fixedly connected with a fixed frame, permanent magnet 2 is fixed in fixed frame.Fixed frame can adopt applicable any concrete structure as required.As there are both ends of the surface, and between both ends of the surface, by two or more connection straps, connecting, permanent magnet 2 can be in fixed frame be inserted in side.The material of fixed frame is elasticity slightly, can be by fastening being placed in fixed frame of permanent magnet 2.Sliding part 7 or action bars can be that integrative-structure also can be fixedly connected with by Split type structure with fixed frame.During manufacture, handle is that axial two parts are formed by connecting, thereby permanent magnet 2 can be placed in cavity 5.But the replacing of the parts such as permanent magnet 2 or sliding part 7 and fixed frame is inconvenience comparatively.So the utility model provide following preferably.
As above-described embodiment preferably, cavity 5 and chute 6 pass to the upper end 402 of handle 4 vertically.Can from the upper end 402 of handle 4, realize at any time like this assembling or the replacing of the parts such as permanent magnet 2 and sliding part 7.In order to prevent that the accident of permanent magnet 2 from deviating from, in the upper end 402 of handle 4, be provided with end cap 8.In order to increase the intensity of handle 4, on end cap 8, cannelure is set, the upper end 402 of handle 4 inserts in this cannelure.Between end cap 8 and handle, can be threaded connection, also can connect by modes such as tensioners.When adopt action bars to be connected with permanent magnet 2 mode time, on end cap 8, should there is the hole that action bars stretches out.
As above-described embodiment preferably, upper end 301 parts of knife bar 3 stretch in cavity 5, permanent magnet 2 has the cavity that holds knife bar 3 201 of axial setting.By the upper end of knife bar 3 is placed in the cavity 201 of permanent magnet 2, make permanent magnet realize parcel to knife bar, increased the magnetic force of cutter head 1.Cavity 201 can be to be formed by the through hole axially arranging along permanent magnet 2, and the blind hole that also can arrange in the one or both ends of permanent magnet 2 forms.
The material that the material of screwdriver of the present utility model all can adopt prior art to adopt.The parts such as handle 4, sliding part 7, fixed frame also can adopt such as applicable any materials such as engineering plastics.Cutter head 1 and knife bar 3 can be integral structures, can be also split-type structurals.
Embodiment 2: as shown in Figure 1, Figure 2 and Figure 3, the controlled screwdriver of a kind of magnetic force, comprise handle and the knife bar being fixedly connected with handle, at its lower end, the other end of described knife bar has cutter head, described knife bar and cutter head are that magnetic conductive metal is made, on described handle, have cavity, the upper end of described knife bar is positioned at described cavity, is provided with movable permanent magnet in described cavity.
As preferably, the axial length of described cavity is greater than the length of permanent magnet, and described permanent magnet can move axially along cavity.
As preferably, on described handle, be provided with vertically and be communicated with the inside and outside chute of cavity, described chute is provided with sliding part, and described sliding part is connected with described permanent magnet.
As preferably, described sliding part is fixedly connected with fixed frame, and described permanent magnet is fixed in fixed frame.
As preferably, described cavity and chute pass to the upper end of handle vertically.
As preferably, the upper end of described handle is provided with end cap.
As preferably, described end cap has cannelure, and the upper end of described handle inserts in described cannelure.
As preferably, described end cap and handle are threaded connection.
As preferably, the upper part of described knife bar is stretched in cavity, and described permanent magnet has the cavity that holds described knife bar of axial setting.
As preferably, described sliding part has two relative clamp bar slots, forms two relative slide rails on the handle of described chute both sides, and two slide rails are stuck in respectively in two clamp bar slots.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
