From will be further understood that the structure of electric tool 10 and triggering system 100 for assembling the following description of the method for electric tool 10 according to the embodiment of the present invention.Will be appreciated that sequential update and/or execution that each step described herein can be different.
CD-ROM drive motor assembly 50 is arranged in the upper cavity part 23A of right casing member 22.Control PCB82 is also close to partition wall 22A and is arranged in upper cavity part 23A, makes trigger switch sensor 112 be positioned at lower cavity part 23B top.
With reference to Figure 10 and 11, magnet 114 is arranged in the magnet bore 174 that triggers member 150.According to some embodiment, magnet 114 is orientated the pole axis and the slip axis almost parallel that triggers member 150 that makes magnet in chamber 174.For example, magnet 114 can be mounted to the front end that the ，Er Qi South Pole, the rear end next-door neighbour who makes its arctic next-door neighbour trigger member 150 triggers member 150.
As shown in Fig. 9 and 10, trigger member 150 and be placed in the seat 136A (Fig. 3) being limited by right casing member 22, triggering pre-installation on member 150 has magnet 114 and spring 176.More specifically, trigger member 150 and place in present 136A, make guide rib 130 be placed in or be landed in guide slit 160, and lower guide rib 132 is placed in or is landed in lower guide slit 162.Thereby magnet 114 next-door neighbour's partition wall 22A location.Spring 176 is trapped in to trigger between member 150 and spring supporting feature 134 and between triggering member 150 and spring supporting feature 134 and is partly compressed.The rear end of spring 176 is laterally slipped into and is captured in spring and catches in slit 134A.
Left outside mould component 24 is arranged on right casing member 22 to form handle 32 and the main body 34 of shell 30.Thereby triggering member 150 is trapped between support feature 127 (Fig. 3 and 4).According to some embodiment, before being installed on right casing member 22, left outside mould component 24 carries out each in aforementioned number of assembling steps.Left outside mould component 24 is installed as and makes the left lateral sides that triggers member 150 be contained in left seat 136B and form whole seat 136 and trigger opening 126.A part that triggers member 150 is outstanding forward by this opening 126. Casing component 22,24 can be secured together by latch feature and/or securing member 5.Spring supporting feature 134 can be contained in the slit with the left outside mould component 24 corresponding spring supporting features 135 of all-in-one-piece (Fig. 4).
In use, operator can optionally activate by triggering system 100 in any suitable manner and stop using for driving the CD-ROM drive motor assembly 50 of driving head 60.
More specifically, trigger member 150 can be present in 136 as shown in the release as shown in Fig. 1,9 and 10 or extended position and Figure 11 return or retracted position between slide.Open space 170 (Fig. 7) provides gap for spring supporting feature 134.In transition between extended position and retracted position, thereby guide slit 160,162 is slided and is limited to the triggering slip axis T-T substantially parallel with upper guiding axis A-A and lower guiding axis B-B by triggering moving of member 150 along guide rib 130,132.As shown in Figure 10, trigger slip axis T-T laterally (and in certain embodiments, substantially vertical) in axis of pitch I-L, extend.According to some embodiment, axis L-L and H-H formation scope are the angle K (Figure 11) from about 70 degree to about 90 degree.
When triggering member 150 in its extended position, (for example, Fig. 9), magnet 114 is orientated as sensor 112 is not activated with respect to hall effect sensor 112.When triggering member 150 is shifted or pulls along retracted orientation TR (Figure 11) by operator, magnet 114 is with respect to hall effect sensor 112 reorientations and activate this sensor 112.When triggering member 150 is released, it turns back to extended position along direction of extension TE (Fig. 9), thereby again with respect to hall effect sensor 112 positioning magnets 114, sensor 112 is not activated.By this way, triggering system 100 can provide a kind of contactless trigger switch system.Yet, according to some embodiment, also can adopt the triggering actuator of other type and structure.Triggering system 100 is used in when retracting or stretching and activates or the motor 30 of stopping using.
According to some embodiment, the scope that triggers the sliding distance Q (Figure 11) of member 150 from extended position to retracted position is from about 6.5mm to 7.5mm.
According to some embodiment, the length P (Fig. 3) of each guide rib 130,132 is at least equally large with the length G (Fig. 6) of relevant guide recess 160,162.According to some embodiment, the scope of the tolerance between the height F (Fig. 8) of height M (Fig. 9) guide recess 160,162 relevant to it of each guide rib 130,132 is from about 2.0mm to about 2.5mm.According to some embodiment, the width N (Figure 10) of each guide rib 130,132 is greater than the degree of depth E (Fig. 8) of its relevant guide recess 160,162.
The assembling of electric tool 10 can be simplified, accelerates and/or be convenient to triggering system 100.Because according to some embodiment, trigger is installed and guide features is all implemented on the right transverse side 154 and right casing member 22 that triggers member 150, so only need triggering member guide features 160,162 to aim at opening right casing member 22.Then left outside mould component 24 can easily be arranged on right casing member 22 and trigger on member 150, and does not need particular job that left outside mould component 24 is aimed at triggering member 150.Because trigger member 150, be directly installed on casing component 22,24 and be captured between casing component 22,24, so assemble the quantity of the required part of triggering system 100, obviously reducing.
Mentioned abovely be only used to the present invention is described and should not be construed as restriction the present invention.Although some exemplary embodiments of the present invention are described, the person skilled in the art will easily understand, in the situation that substantially not departing from novel teachings of the present invention and advantage, the many modifications in exemplary embodiment are possible.Therefore, all such modifications are all intended to be included within the scope of the invention.Therefore, will be appreciated that, be only used for above the present invention is described and should be understood to be confined to disclosed specific embodiment, and the modification of the disclosed embodiments and other embodiment are all intended to be included within the scope of the invention.
