在机修工作中常用拉具拆卸轮类或轴承零件,一般拉具的三条拉臂不能同时调整,操作麻烦,容易损伤工件。为此,我们设计制造了可调式轮类拉具,使用良好。 In the mechanical repair work, puller is usually used to disassemble the wheel or bearing parts. Generally, the three pull arms of the puller cannot be adjusted at the same time. The operation is troublesome and the workpiece is easily damaged. For this reason, we have designed and manufactured adjustable wheel pullers that are well-used.
