Welding machine ground wire pincers

The utility model discloses a welding machine ground wire pincers, its characterized in that: including C type body, the terminal fixedly connected with thread bush in upper end of C type body, lower tip fixedly connected with conducting block is still including passing the thread bush, rather than the matched with screw rod, the end -to -end connection of screw rod has electrically conductive screw cap, still be provided with on the C type body one with the corresponding ground wire hole in conducting block position. Driving the screw rod up -and -down motion through cross knob rotation, at the electrically conductive screw cap of copper during with the contact of copper conducting block, can combining closely, calorific capacity is little in the use, dismantles simply, easy and simple to handle, and has good electric conductive property, and the security is high, greatly reduced change the frequency that the ground wire clamped, practiced thrift the cost, improved the quality. 本实用新型公开了种焊机地线钳，其特征在于：包括C型本体，所述
