我们参照美国的展品,设计了一套小型手工配管工具。这种工具适于液压、气动或润滑系统的紫铜管路配置及扩口管接头密封的制作(图1)。它小巧玲珑、携带方便、性能优于一些常用的同类工具。小型手工配管工具由弯管器、切管器及管子扩口器三件组成。一、弯管器:管路的配置需要有许多不同角度及走向的弯曲来实现,弯管器是达此目的的优良手工具。弯管器由管胎5、能卡紧管子的钩爪3及用连接板9和 We refer to the exhibits in the United States, designed a small hand-plumbing tools. This tool is suitable for the configuration of copper piping in hydraulic, pneumatic or lubrication systems and the production of flared pipe fittings (Figure 1). It is small and exquisite, easy to carry, performance is superior to some commonly used similar tools. Small manual plumbing tools from the pipe, pipe cutters and pipe flares three components. First, the bender: the configuration of the pipeline need to have many different angles and the direction of the curved to achieve, bender is an excellent hand tools for this purpose. Tube bender tube by tube 5, can grip the hook claws 3 and the use of connecting plate 9 and
