Claims

[Claims for Utility Model Registration] (A) Batters box frame A, which consists of vertical rods 1 and 2 and horizontal rods 3 and 4, based on the regulations for baseball and softball, is shaped like a home plate. It is connected in parallel to a basic rod 6 fixed to the longitudinal center line of the rod 5 by connecting rods 7 and 8. (a) The horizontal rod 3 and the vertical rod 1, the horizontal rod 4 and the vertical rod 2, the vertical rod 1 and the connecting rod 7, the basic rod 6 and the connecting rods 7 and 8 are connected by pins 9, and Vertical rod 1
- 2 and the connecting rod 8 are fixed by pins 10 so as to be flexible and extensible. (C) Horizontal rod 3, vertical rods 1 and 2, tip 11
Supplementary rod 12 is connected to lateral rod 4, which is connected by cap 13, is extended in a straight line, and starting from the tip 14 of lateral rod 3, pitcher's plate length 15 and sleeve line width 16 are determined according to regulations.
, length from fur line to coachyard box: 17, coachyard box length and coachyard depth: 18, coachyard box length: 1
9 are displayed respectively. (d) The radius of the butters-on-deck circle f starting from the base 24 of the supplementary rod 12 is the protrusion 2.
By 0, the radius g of the pitcher's mound starting from the base 22 of the basic rod 6, which connects the supplementary rod 12 to the tip 21 by the cap 13, is indicated by the protrusion 23. (e) As shown in Figs. 5 and 6, the rod is folded and contracted, wrapped around the rod by the home base shape 5, and fixed with a string 25 with a mounting device 26 for storage. A portable diamond wire drawing tool constructed as described above.
