The invention proposes a general adjustable round nut spanner. The general adjustable round nut spanner comprises a force application rod, a first tension rod, a second tension rod, a movable pressure rod, an extension mechanism and a stress head, wherein round holes are respectively formed in one ends of the first tension rod, the movable pressure rod and the second tension rod; locking nut tension heads are respectively fixed at the other ends of the first tension rod and the second tension rod; the extension mechanism is mounted on the movable pressure rod; the stress head is mounted at the other end of the extension mechanism for changing a distance between the movable pressure rod and the stress head; and the force application rod penetrates through the round holes in the first tension rod, the movable pressure rod and the second tension rod in sequence. The general adjustable round nut spanner can be suitable for round nuts with different sizes, solves the locking and disassembly problems of the round nuts, reduces the damage of the round nuts, and widens the application range of the round nuts.
Description
technical field [0001] The invention relates to a universal adjustable round nut wrench. Background technique [0002] Round nuts are often used in occasions where the force is small, the space is small, and loosening is prevented, and they are used in conjunction with anti-loosening washers; they are especially widely used in locking shaft moving parts. The use conditions of the round nut make it difficult to lock and disassemble, especially when disassembly often uses destructive means, which can easily damage the round nut. Simultaneously, because the locking force of the round nut is not large, the use of the round nut is limited. The common round nut wrenches on the market basically only use one slot of the round nut for locking and dismounting. On the one hand, the force is relatively concentrated, and the round nut is easy to damage; on the other hand, the locking force is small, so that the application range of the round nut is narrow.
