Description

  The present invention relates to a turning operation tool.

  Conventionally, for example, as shown in FIG. 10, there has been proposed a jack device J that is installed between a base (not shown) in a building and a large pull 51 and supports the large pull 51.

  As shown in FIG. 11, the jack device J has a working shaft 2 composed of a cylindrical body 2a and a screw rod-shaped body 2b fitted into the cylindrical body 2a. When the operating shaft operating handle portions 3A and 3B that are screwed onto the body 2b and project in opposite directions from the threaded rod-shaped body 2b and are fitted in a relatively rotatable manner are rotated, the threaded rod-shaped body The operating shaft operating handle portions 3A and 3B (screwed portions 3C) are screwed with respect to 2 and moved relative to each other in the vertical direction, so that the screw rod-like body 2b is moved in the vertical direction (FIG. 11). The structure is such that the action shaft 2 expands and contracts by relative movement in the middle arrow a direction). Reference numeral 18 denotes a connecting portion for connecting to the large drawer 51.

  Therefore, the installation work and the removal work of the jack device J are performed by rotating the action shaft 2 by rotating the action shaft operating handles 3A and 3B.

  By the way, this jack apparatus J is removed after forming an upper structure composed of joists 52, plywood 53, concrete slabs 54, etc. on the large pull 51 supported by the jack apparatus J. The jack apparatus J is removed. At this time, even if the action shaft operation handle portions 3A and 3B are rotated to contract the jack device J, the expansion / contraction structure (the screw rod-like body 2a and the action shaft operation handle portions 3A and 3B are screwed together). Since a very large load is applied to the structural part), even if the operating shaft operating handle portions 3A and 3B are grasped and rotated by hand, the operating shaft operating handle portions 3A and 3B are rigid and rotate. It may not be possible to Even if the operating shaft operating handle portions 3A and 3B can be gripped and rotated by hand, a very strong force is required and is serious.

  Therefore, in the prior art, the working shaft operating handle portions 3A and 3B, which are hard and cannot be rotated in this way (having become difficult to rotate), are rotated by hitting them with a hammer or the like at the site. I am doing so.

  However, the action shaft operation handle portions 3A and 3B may be damaged by bending or bending the action shaft operation handle portions 3A and 3B, and the jack device J is removed. If there are pillars, scaffolds, etc. around it, there is a problem that the operating shaft operating handles 3A and 3B may not be able to be rotated well because they are narrow and cannot be struck sufficiently. .

  The present invention provides an epoch-making tool for rotating operation that solves the above-described problems and exhibits unprecedented effects.

  The gist of the present invention will be described with reference to the accompanying drawings.
