Claims

[Claims for Utility Model Registration] 1. A holding cylinder 2 fitted into the screw shaft 1 is provided with a pin member D described in A below on the circumference corresponding to the lead of the screw S of the screw shaft 1. When the number of pin members D to be attached is N, holes H are drilled at positions of 1/N x leads, and the pin members D are fitted and attached to the mounting holes H, and the end of the pin P is attached to the screw shaft. A rolling pin screw that is meshed with the thread groove of No. 1. (a) Two ball bearings 3, 3' are placed one on top of the other with a spacer ring 4 in between, and the base of a pin P is inserted and fixed into the inner ring of the two ball bearings 3, 3', and the pin When fitting and fixing the bearing group to the bush 5, fit and fix the bearing group to the bush 5 so that the center line of the bush 5 and the axis of the pin P are offset, and a groove M for a screwdriver is provided on the bottom of the bush. Pin member D. 2. When the screw S of the screw shaft 1 has a square cross-section, the end of the pin P of the pin member D is a round bar with a semicircular head,
The rolling pin screw according to claim 1, wherein the pin P is provided with a flange F, and the distance between the pin head and the flange F is shorter than the depth of the screw S. 3 When the screw S of the screw shaft 1 has a trapezoidal cross-section, the pin end of the pin member D is shaped like a truncated cone, and a flange F is provided at the base of the truncated cone, and from the truncated surface of the cone to the flange. The rolling pin screw according to claim 1, wherein the distance between S and S is shorter than the depth of the screw S. 4 When the cross-sectional shape of the screw S of the screw shaft 1 is triangular, the end of the pin P of the pin member D is conical, and the conical ceramic is provided with a flange F, and the distance from the conical end to the flange is determined by the depth of the screw S. The rolling pin screw according to claim 1, which is a utility model, and is characterized in that it has a shorter length.
