Abstract

Conventional ring spanners and general spanners are limited in tightening or loosening a tightening nut connected or fastened to a middle portion of a pipe in a narrow space. To rotate such a tightening nut to safely tighten and loosen the nut by allowing a large force to reach the circumference of the nut, an inlet of a prescribed size is opened on an inlet portion of a ring spanner and an inlet is opened on an inner ratchet wheel to match the prescribed size to insert a tightening nut on a middle portion of a pipe into the inlet of the ring spanner to fasten the nut. One or more ratchet members separated by a prescribed distance to function as a ratchet are formed on a stop gear of the ratchet wheel in accordance with the size of the inlet. Specifically, the ratchet wheel of the ring spanner can be rotated in a narrow space to increase work efficiency, and a nut requiring precise tightening can be safely tightened and loosened. In addition, the ring spanner can be manufactured by a method of manufacturing conventional spanners, and thus economic manufacture is possible.

Description

Ratchet ring spanner with open opening. {Latch ring spanner with inlet.}

The present invention relates to a ratcheted ring spanner with an inlet opening that can open and close the fastening nut located at the end and the middle of the intermediate locking pipe.

More specifically, the conventional ring spanner is used only to fit the head of the bolt located at the end because the inlet is blocked.

The present invention includes a ratchet wheel with an inlet opening and a ratchet opening with an opening of the same size as the head.

Depending on the size of the inlet, one or more stop gears are formed in the stop gear of the ratchet wheel, which are formed at a certain distance to be engaged by the stop gear.

The stop gear as described above is characterized in that it is formed at a certain distance to the size of the inlet.

   Conventional ratchet type ring spanners have a handle and a head portion and have a circular section for receiving a ratchet wheel in the head portion. However, a gear is latched on a circular circumferential wall for operating the ratchet wheel so as to engage with a plurality of gears on the outer circumferential surface of the ratchet wheel to stop.

That is, the tightening nut located in the intermediate portion formed to extend or connect the pipe is limited to the use of a conventional ring spanner, so that a general spanner having an inlet opening is used.

However, the place where the tightening nut in the middle of the pipe is located in a narrow space is often inconvenient to work with a conventional ring spanner or a general spanner.

In particular, these fastener nuts require a great deal of precision, and in order to be fastened or loosened, they must be secured or tightened securely so that the entire circumference of the fastener nut can be applied.

 The present invention includes a head portion having an inlet opening and a ratchet wheel having an opening having the same size as the head portion with an innovative ring spanner which improves the above problems.

Depending on the size of the inlet, it is possible to form one or more stop gears that are formed at a certain distance that can be latched to the stop gear of the latch wheel.

The stop gear as described above is characterized in that it is formed at a certain distance to the size of the inlet.

If the above stop gear is located in the disconnected part by a certain distance, the ratchet wheel is rotated by another stop gear that is not located in the disconnected part to rotate and transmit the force to the ratchet wheel continuously. The feature is that it can be done.
