Title:
GRIP ANGLE ADJUSTING DEVICE
Document Type and Number:
Japanese Patent JP3665386
Kind Code:
B2
Abstract:
PURPOSE: To improve work efficiency by enabling a grip angle to be freely changed, to prevent displacement of a preset angle due to vibration or the like, and to easily realize an ideal work attitude of a tool handling.
CONSTITUTION: A grip angle adjusting device 15 comprises a grip base 16, external templet 17, internal templet 18, grip angle fixing bolt 19, grip main unit 20 and a fixing nut 21. A support plate 16c having a dome-shaped curved surface is formed in an upper part of the grip base 16, to insert the grip angle fixing bolt 19 to a spread hole H of this support plate 16c. The external/internal templets 17, 18 are respectively provided inside/outside the support plate 16c, so as to interpose it by each templet 17, 18 with tightening force of the fixing nut 21. When a grip angle is adjusted, when the grip main unit 20 and the grip angle fixing bolt 19 are integrally rotated around a shaft, the fixing nut 21 is untightened, so that the grip angle can be adjusted.
