Accelerator adjusting device for diesel engine test room

The utility model discloses an accelerator adjusting device for a diesel engine test room, which comprises an accelerator oscillating bar rotatably arranged on an accelerator base and an iron fork movably connected with the accelerator oscillating bar, a magnet is adsorbed at the tail end of the iron fork, a ball head is adsorbed at the other end of the magnet, the ball head is fixedly connected with a screw rod, the screw rod is in threaded connection with a screw rod fixing block, and the screw rod fixing block is in threaded connection with the accelerator base. The accelerator swing rod fine adjustment device is simple in structure, the screw pitch of the screw rod is small enough, and fine adjustment of the accelerator swing rod can be achieved. In the process that the screw moves rightwards or leftwards, the ball head is connected with the iron fork through the magnet all the time, the ball head can adapt to angle changes of the accelerator swing rod and the iron fork and can also guarantee rotation of
