　　電(dian)動工具選購技(ji)巧

　　1、如果(guo)您(nin)(nin)經常在混凝(ning)土墻上(shang)(shang)(shang)鉆(zhan)孔(kong)，那么一臺(tai)兩(liang)公斤電(dian)錘是您(nin)(nin)的(de)(de)選擇。由(you)于電(dian)錘的(de)(de)氣缸結(jie)構，捶打力非常高，并(bing)具有(you)每分(fen)(fen)鐘1，000到3，000的(de)(de)捶打頻率(lv)，可(ke)產生(sheng)顯著的(de)(de)力，使您(nin)(nin)在混凝(ning)土墻上(shang)(shang)(shang)鉆(zhan)孔(kong)輕(qing)而易舉(ju)。配上(shang)(shang)(shang)一個(ge)轉(zhuan)接桿(gan)和普通電(dian)鉆(zhan)的(de)(de)卡(ka)頭，它還能完成(cheng)(cheng)手(shou)電(dian)鉆(zhan)功能，達到一機多用的(de)(de)目的(de)(de)。就(jiu)是調(diao)速(su)電(dian)錘+轉(zhuan)接桿(gan)+13毫米(mi)電(dian)鉆(zhan)卡(ka)頭，只需幾(ji)百元，再配上(shang)(shang)(shang)幾(ji)支常用的(de)(de)鉆(zhan)頭，那么您(nin)(nin)家(jia)里的(de)(de)大部(bu)分(fen)(fen)裝修任(ren)務就(jiu)可(ke)以(yi)自(zi)己完成(cheng)(cheng)了。

　　2、如果除了混(hun)凝土(tu)鉆(zhan)孔(kong)，還要兼顧在(zai)木(mu)材和金屬上鉆(zhan)孔(kong)，并且(qie)在(zai)混(hun)凝土(tu)上鉆(zhan)孔(kong)在(zai)十毫米以下，就可以考(kao)慮沖(chong)(chong)擊鉆(zhan)，沖(chong)(chong)擊鉆(zhan)靠(kao)斜齒輪產(chan)生沖(chong)(chong)擊，沖(chong)(chong)擊力不如電錘。

　　3、如果您(nin)經常上緊或松(song)(song)開螺釘，或者在(zai)(zai)木板或鐵板上打孔，那么您(nin)可以(yi)購買一把充電式的電動起(qi)子(zi)，它(ta)在(zai)(zai)這兩個方面(mian)是方便的工(gong)具(ju)。充電式電動起(qi)子(zi)再加(jia)上一套起(qi)子(zi)頭套裝，輕松(song)(song)搞(gao)定(ding)您(nin)手頭的工(gong)作。

　　4、手電鉆(zhan)(zhan)大家肯定(ding)都知道，它適合在木板或者鐵板上(shang)打孔，但是(shi)千萬不(bu)要指(zhi)望它在混凝(ning)土墻上(shang)鉆(zhan)(zhan)孔有多大作為,那(nei)樣做很容易損壞機(ji)器，一只(zhi)手電鉆(zhan)(zhan)是(shi)經濟(ji)的電動工具，即(ji)使是(shi)進(jin)口的，也只(zhi)需要幾百元。

　　5、曲線(xian)(xian)鋸，如果(guo)您(nin)的(de)動(dong)手能(neng)力(li)很強，可以自(zi)己(ji)(ji)做一(yi)些家具或者造型，那(nei)么曲線(xian)(xian)鋸您(nin)肯定需要，裝卡上合適的(de)鋸條，木(mu)板、鐵(tie)板、塑(su)料板、不銹鋼(gang)等等很快就能(neng)在(zai)您(nin)手下加工(gong)出(chu)您(nin)理想的(de)形狀.您(nin)可以選擇各種型號的(de)曲線(xian)(xian)鋸，創造屬于您(nin)自(zi)己(ji)(ji)的(de)造型。

　　電動(dong)工(gong)具選購(gou)技巧(qiao)

　　1、如果您經(jing)常(chang)在混凝(ning)土(tu)墻(qiang)(qiang)上(shang)鉆(zhan)孔(kong)，那么(me)一臺(tai)兩公斤電錘(chui)是您的(de)(de)(de)選擇。由于電錘(chui)的(de)(de)(de)氣缸結構(gou)，捶(chui)打(da)力非常(chang)高，并具有(you)每分鐘1，000到(dao)3，000的(de)(de)(de)捶(chui)打(da)頻率(lv)，可產生顯著(zhu)的(de)(de)(de)力，使(shi)您在混凝(ning)土(tu)墻(qiang)(qiang)上(shang)鉆(zhan)孔(kong)輕而(er)易舉。配上(shang)一個轉(zhuan)(zhuan)接(jie)桿(gan)和普通電鉆(zhan)的(de)(de)(de)卡(ka)頭(tou)，它還能完成手電鉆(zhan)功能，達(da)到(dao)一機(ji)多用的(de)(de)(de)目(mu)的(de)(de)(de)。就(jiu)是調速(su)電錘(chui)+轉(zhuan)(zhuan)接(jie)桿(gan)+13毫(hao)米電鉆(zhan)卡(ka)頭(tou)，只需(xu)幾(ji)百元，再配上(shang)幾(ji)支常(chang)用的(de)(de)(de)鉆(zhan)頭(tou)，那么(me)您家里的(de)(de)(de)大部分裝修(xiu)任務就(jiu)可以(yi)自(zi)己完成了(le)。

　　2、如(ru)果除了(le)混凝土鉆孔，還要兼顧在(zai)木材和金屬上鉆孔，并且在(zai)混凝土上鉆孔在(zai)十毫米以下，就(jiu)可以考慮沖擊(ji)鉆，沖擊(ji)鉆靠(kao)斜齒輪產生沖擊(ji)，沖擊(ji)力不如(ru)電錘(chui)。

　　3、如果您(nin)經(jing)常上(shang)緊或(huo)松開螺釘，或(huo)者在木(mu)板或(huo)鐵板上(shang)打孔，那么您(nin)可以購買一(yi)把(ba)充電式的電動起子(zi)，它在這(zhe)兩個方面(mian)是方便的工具。充電式電動起子(zi)再加上(shang)一(yi)套起子(zi)頭套裝，輕(qing)松搞定您(nin)手頭的工作。

　　4、手電鉆大家肯定(ding)都知道(dao)，它(ta)適合在(zai)木板(ban)或(huo)者鐵板(ban)上(shang)打孔，但是(shi)千萬不要(yao)指望它(ta)在(zai)混凝土墻上(shang)鉆孔有多大作為,那樣做很(hen)容(rong)易損(sun)壞(huai)機器(qi)，一只手電鉆是(shi)經濟的電動工具，即使是(shi)進口的，也只需要(yao)幾百元。

　　5、曲(qu)(qu)線(xian)(xian)(xian)鋸(ju)，如果(guo)您的動手(shou)能力很強(qiang)，可(ke)以(yi)(yi)自(zi)己做一些家具(ju)或者(zhe)造型，那么曲(qu)(qu)線(xian)(xian)(xian)鋸(ju)您肯定需(xu)要，裝卡上(shang)合適的鋸(ju)條，木板、鐵板、塑(su)料(liao)板、不銹鋼等等很快(kuai)就能在您手(shou)下加(jia)工(gong)出您理想的形狀.您可(ke)以(yi)(yi)選(xuan)擇各種型號的曲(qu)(qu)線(xian)(xian)(xian)鋸(ju)，創造屬于您自(zi)己的造型。
