向きな問題点をイｊしていた。As is well known, conventional spanners are attached to the head of the bolt, or the nut (
(hereinafter abbreviated as /1)) is removed from the lifting platform (*).
I used it after removing it from the nut in the second round, and the surface was not lined up, but it was 5j1 efficient. For this reason, spanners that do not need to be removed from the nut each time have been researched and implemented.・(・I was ignoring a problem that made it unsuitable for use by Teru.

のである。The present invention solves this problem by solving this problem with a simple design that is no different from the shape of the mouth of a conventional wrench.
'It can be tightened continuously without having to remove it from Natsu each time.'
This item was invented for the purpose of providing a wrench that can be retracted and retracted.

As shown in the figure, one side of the nut A is held down by the normally forming surface A of the wrench, and even the corner Iia+++ of the other side is held down by the lower surface 6 of the stop bow 3, so that it is not affected by the normal rotational force of the wrench. i(r) It is a good idea to do this. When the second rotation is completed and the spats are rotated, the lower part u6 of the holding piece 3 will slide into contact with one side of the nut.

Claims

[Claims]

(1) One gripping surface at the mouth of the wrench is formed into a nearly semicircular shape to provide a nut relief surface, and a holding piece with a relief radius formed inside the tip side is attached to the inner periphery of the nut relief. 11 (opened and provided at the tip approximately in the middle position)
Loosely fit the movable pc into the rib groove in the front and back force direction, press the holding stopper piece continuously, and the inner surface of the holding stopper j'I slides into contact with the outer periphery of the /1.
