Jumbolter torque multiplier

The invention discloses a jumbolter torque multiplier and belongs to the technical field of tool articles. The jumbolter torque multiplier comprises a body (1), wherein a connecting rod (2) is perpendicularly arranged on the outer side wall of the body (1); the jumbolter torque multiplier further comprises a fixed rack (3); one end of the fixed rack (3) is connected with the connecting rod (2); and the other end of the fixed rack (3) can be fixed. According to the jumbolter torque multiplier, one end of the fixed rack (3) is connected with the connecting rod (2), the other end of the fixed rack (3) is fixed, and the connecting rod is fixed through the fixed rack (3) to realize the purpose of fixing the shell of the body (1) of the jumbolter torque multiplier. The jumbolter torque multiplier is simple in structure and also solves the problem that a mechanical accident is likely to take place when the shell of the existing jumbolter torque multiplier is manually fixed. 本发明公开了一种锚杆钻机扭矩倍增器，属于工具用品技术领域。本装置的锚杆钻机扭矩倍增器
