一、用途当我们校验或检修各种流量表、压力表、远程压力表……时,往往要把指针取下,调校后装上,反复调校多次,反复拆装多次。过去的老办法取针,是用螺丝刀撬,或尖咀钳拔,很容易把轴撬弯,致使贵重的表不能使用。而市场上也没有合适的工具可买。在这情况下试制了本图介绍的“起针钳”,在现场使用后证明起针灵巧,吐针方便,结构简单,一般单位都能
First, use When we check or overhaul all kinds of flow meters, pressure gauges, remote pressure gauges ... ..., it is often necessary to take off the pointer, adjusted after the installation, repeatedly adjusted repeatedly, repeated disassembly multiple times. In the past, the old method of taking a needle was prying it with a screwdriver or pulling it with a sharp-pointed jaw. It is easy to pry the shaft so that valuable watches can not be used. There is no suitable tool available on the market. In this case trial production of the “introduction needle”, the use of the scene proved dexterity, spit needles convenient, simple structure, the average unit can
