Title:
POWER TOOL
Document Type and Number:
Japanese Patent JP3437796
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To substantially improve performance over the whole by arranging an inner sleeve on the axis at actuating time in response to at least one of interacting tool means of the driving part and the housing part.
SOLUTION: A tool means 1 is composed of the driving part 2 and the housing part 3 of two interacting parts. The sleeve part 10 is provided with an inner sleeve 12 having an outside screw for engaging with an inside screw of an outer sleeve 11. When a driving plate 4 rotates, a ratchet 5 rotates along the axis O so that the ratchet 5 coaxially rotates the outer sleeve 11 through a ring 6 and a socket 7. The inner sleeve 12 moves upward on the axis O in response to rotation of the outer sleeve 11, so that the housing part 3 joined to a reaction shaft 8 and a reaction shaft 8 also moves on the axis O to thereby install or relax a screwing-in connector meshing with the inner sleeve 12.
