　　電(dian)動工具選購技巧

　　1、如(ru)果您經常(chang)(chang)在混凝(ning)土墻(qiang)上鉆(zhan)孔，那(nei)(nei)么一(yi)臺兩公斤電(dian)(dian)錘是您的(de)(de)(de)選擇。由(you)于電(dian)(dian)錘的(de)(de)(de)氣缸結構，捶打力(li)非常(chang)(chang)高，并(bing)具有每分鐘1，000到(dao)3，000的(de)(de)(de)捶打頻率(lv)，可產生顯著的(de)(de)(de)力(li)，使您在混凝(ning)土墻(qiang)上鉆(zhan)孔輕而易舉。配上一(yi)個轉接(jie)桿和(he)普通電(dian)(dian)鉆(zhan)的(de)(de)(de)卡頭，它(ta)還能完(wan)成(cheng)手(shou)電(dian)(dian)鉆(zhan)功(gong)能，達到(dao)一(yi)機多(duo)用的(de)(de)(de)目的(de)(de)(de)。就是調(diao)速電(dian)(dian)錘+轉接(jie)桿+13毫米電(dian)(dian)鉆(zhan)卡頭，只需(xu)幾(ji)百元，再(zai)配上幾(ji)支常(chang)(chang)用的(de)(de)(de)鉆(zhan)頭，那(nei)(nei)么您家里的(de)(de)(de)大部(bu)分裝修任務就可以自己(ji)完(wan)成(cheng)了。

　　2、如(ru)果除了(le)混凝土鉆(zhan)(zhan)(zhan)孔，還要兼顧在木材和金屬上鉆(zhan)(zhan)(zhan)孔，并且在混凝土上鉆(zhan)(zhan)(zhan)孔在十毫米以下(xia)，就可以考慮沖(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)，沖(chong)擊(ji)(ji)鉆(zhan)(zhan)(zhan)靠斜齒輪產生(sheng)沖(chong)擊(ji)(ji)，沖(chong)擊(ji)(ji)力不如(ru)電錘。

　　3、如果您經常(chang)上緊或(huo)松(song)開螺釘，或(huo)者在(zai)木板或(huo)鐵板上打孔，那(nei)么您可以(yi)購買一(yi)(yi)把充電(dian)(dian)式的(de)電(dian)(dian)動(dong)起子(zi)，它(ta)在(zai)這(zhe)兩個方(fang)(fang)面是(shi)方(fang)(fang)便的(de)工(gong)具(ju)。充電(dian)(dian)式電(dian)(dian)動(dong)起子(zi)再加上一(yi)(yi)套(tao)起子(zi)頭套(tao)裝(zhuang)，輕松(song)搞定您手(shou)頭的(de)工(gong)作。

　　4、手(shou)電(dian)鉆大家(jia)肯定(ding)都知道(dao)，它(ta)適合在(zai)木(mu)板或者鐵板上打孔，但(dan)是(shi)千萬不要(yao)指望(wang)它(ta)在(zai)混凝土墻上鉆孔有多(duo)大作為,那樣做很容易損壞機器，一只(zhi)手(shou)電(dian)鉆是(shi)經濟的(de)電(dian)動工具，即使是(shi)進口(kou)的(de)，也只(zhi)需要(yao)幾百元。

　　5、曲線鋸(ju)，如果您的動手能力很強，可以自己(ji)做(zuo)一些家具或者造型(xing)，那么曲線鋸(ju)您肯定需要，裝卡上合適的鋸(ju)條，木板、鐵板、塑料(liao)板、不銹鋼(gang)等等很快就(jiu)能在您手下加(jia)工(gong)出您理想的形(xing)狀.您可以選擇各種(zhong)型(xing)號的曲線鋸(ju)，創造屬于您自己(ji)的造型(xing)。

　　電(dian)動工具選購技巧

　　1、如果您經常在(zai)混凝土墻(qiang)上鉆(zhan)(zhan)(zhan)孔(kong)，那(nei)么(me)一臺(tai)兩公斤(jin)電(dian)(dian)(dian)錘(chui)是(shi)您的(de)(de)(de)選擇。由于(yu)電(dian)(dian)(dian)錘(chui)的(de)(de)(de)氣缸結構，捶(chui)打力(li)非(fei)常高(gao)，并具(ju)有每分鐘1，000到3，000的(de)(de)(de)捶(chui)打頻率，可(ke)產(chan)生顯著的(de)(de)(de)力(li)，使您在(zai)混凝土墻(qiang)上鉆(zhan)(zhan)(zhan)孔(kong)輕而易舉。配上一個(ge)轉(zhuan)接桿(gan)和普通(tong)電(dian)(dian)(dian)鉆(zhan)(zhan)(zhan)的(de)(de)(de)卡(ka)頭，它還能(neng)完成手電(dian)(dian)(dian)鉆(zhan)(zhan)(zhan)功(gong)能(neng)，達(da)到一機多用的(de)(de)(de)目的(de)(de)(de)。就(jiu)是(shi)調速電(dian)(dian)(dian)錘(chui)+轉(zhuan)接桿(gan)+13毫米電(dian)(dian)(dian)鉆(zhan)(zhan)(zhan)卡(ka)頭，只需幾百元，再配上幾支(zhi)常用的(de)(de)(de)鉆(zhan)(zhan)(zhan)頭，那(nei)么(me)您家(jia)里的(de)(de)(de)大(da)部分裝修任(ren)務就(jiu)可(ke)以(yi)自己完成了。

　　2、如果除(chu)了混凝土(tu)鉆(zhan)(zhan)(zhan)孔，還要兼顧在(zai)(zai)木(mu)材和金屬上(shang)鉆(zhan)(zhan)(zhan)孔，并(bing)且在(zai)(zai)混凝土(tu)上(shang)鉆(zhan)(zhan)(zhan)孔在(zai)(zai)十毫米以下，就可以考慮沖擊(ji)鉆(zhan)(zhan)(zhan)，沖擊(ji)鉆(zhan)(zhan)(zhan)靠(kao)斜齒輪(lun)產生沖擊(ji)，沖擊(ji)力不如電錘。

　　3、如果您經常上(shang)緊或松(song)開螺(luo)釘，或者在木板或鐵板上(shang)打孔，那么您可以購買一(yi)把充電式(shi)的(de)(de)電動起(qi)子，它在這兩個方面是方便的(de)(de)工具。充電式(shi)電動起(qi)子再加上(shang)一(yi)套(tao)起(qi)子頭(tou)套(tao)裝，輕松(song)搞定您手頭(tou)的(de)(de)工作。

　　4、手(shou)電鉆(zhan)(zhan)大家(jia)肯定都知(zhi)道，它(ta)適合在(zai)木板(ban)或者鐵板(ban)上打孔(kong)，但是(shi)千萬不要(yao)指望它(ta)在(zai)混(hun)凝土墻上鉆(zhan)(zhan)孔(kong)有(you)多(duo)大作為,那樣做很(hen)容易損(sun)壞(huai)機器，一只手(shou)電鉆(zhan)(zhan)是(shi)經(jing)濟(ji)的電動(dong)工具，即使是(shi)進口的，也只需要(yao)幾百元。

　　5、曲(qu)線鋸(ju)(ju)，如果您的動手能(neng)力(li)很強，可(ke)(ke)以自己做(zuo)一些家具或(huo)者造(zao)(zao)型，那么曲(qu)線鋸(ju)(ju)您肯定需要，裝(zhuang)卡上合適的鋸(ju)(ju)條(tiao)，木板、鐵(tie)板、塑料板、不(bu)銹鋼等等很快就(jiu)能(neng)在您手下加工出您理想的形狀.您可(ke)(ke)以選擇(ze)各(ge)種(zhong)型號的曲(qu)線鋸(ju)(ju)，創造(zao)(zao)屬于您自己的造(zao)(zao)型。
