The invention provides a plug uninstalling and fastening wrench for railway locomotive maintenance. The plug uninstalling and fastening wrench comprises two connecting rods, one end of the connecting rods are clamp handle parts, the other ends of the connecting rods are clamp head parts, the number of the connecting rods is two, the two connecting rods are hinged through a hinge shaft, the clamp head parts have arc-shaped structures, and anti-skid units are arranged on the inner sides of the arc-shaped structures and used for preventing the clamp head parts and a shell of the to-be-uninstalled aviation plug from moving relatively, front-end buckles are arranged at the ends, away from one end of the clamp handle part, of the clamp head parts, and the front-end buckle is used for being inserted into a socket of an inner core of a to-be-uninstalled-installed aviation plug. The plug uninstalling and fastening wrench for the railway locomotive maintenance has the beneficial effects that the plug uninstalling and fastening wrench for the railway locomotive maintenance is simple in force application, more labor is saved compared with manual operation, and the wrench is suitable for a narrow space, and the clamping surface is provided with the insection part made of a hard plastic material, so that the contact friction force is increased on one hand, and on the other hand, the damage to the plug during use is reduced relative to a metal contact surface.

    本发明提供了一种铁路机车检修用插头拆卸紧固扳手,包括连接杆,连接杆一端为钳柄部,另一端为钳头部,所述连接杆设有两根,两根连接杆之间通过铰接轴铰接;钳头部具有弧形结构,弧形结构内侧设置有防滑单元,用于防止钳头部与待拆装航空插头的外壳相对移动;钳头部远离钳柄部一端的端部设置有前端卡扣,所述前端卡扣用于插入待拆装航空插头的内芯的插口内。本发明有益效果:一种铁路机车检修用插头拆卸紧固扳手发力简单,相比于用手更加省力,且适用于狭小空间;夹持面设有硬塑料材质的齿纹部,一方面增大了接触的摩擦力,另一方面相对于金属的接触面减少了使用时对插头造成损伤。
