By tilting the operation lever 34 coupled to the eccentric circular cam 35, the eccentric circular cam 35 rotates, and the slider plate 32 and the metal fitting holding portion 31 can be slid.

  The usage method of the slate roof repair tool 1 having such a configuration is as follows. FIG. 6 is an explanatory diagram showing how to use the slate roof repair tool 1.

  First, the clamp metal fitting 5 is set from the direction of the arrow A in the figure to the metal fitting holding part 31 of the operation unit 3. Since the metal fitting holding portion 31 is opened over the entire surface on the side where the clamp metal fitting 5 is inserted, the clamp metal fitting 5 can be easily set. The clamp metal fitting 5 inserted into the metal fitting holding portion 31 is held by the positioning rib 311. At this time, when the rib 53 of the clamp fitting 5 is set so as to contact the inner surface of the pushing portion 313 of the fitting holding portion 31, the fitting groove 54 of the clamp fitting 5 has its opening edge in the axial direction of the hook bolt 8. Directed.

  Next, the hook portion 22 of the main body 2 is hooked on the shaft portion 81 of the hook bolt 8 protruding from the peak portion of the existing slate roof material 7 from above the hook bolt 8 or from the direction of the arrow B. . As shown in the drawing, the opening direction (arrow B) of the latching portion 22 latched on the hook bolt 8 is opposite to the insertion direction (arrow A) of the clamp metal fitting 5 with respect to the metal fitting holding portion 31. It is formed to become. The latching position of the latching portion 22 is preferably directly above the fixing nut 82 screwed into the hook bolt 8.

  After the shaft 81 of the hook bolt 8 is hooked on the hook 22, the handle 21 is pressed with one hand to fix the main body 2 on the existing slate roof material 7, while the other hand is used to operate the operating section 3. The lever 34 is pushed down. As a result, the eccentric circular cam 35 rotates to pressurize the slider plate 32 in the lateral direction, and slide the metal fitting holding portion 31 in the lateral direction.

  When the operation lever 34 is further tilted, the clamp fitting 5 held by the fitting holding portion 31 is press-fitted around the axis of the hook bolt 8. The position where the fitting groove 54 of the clamp fitting 5 is press-fitted is preferably at the lower part of the washer 83 of the hook bolt 8, but may be between the fixing nut 82 and the washer 83. The recess 24 (see FIGS. 2 and 4) formed on the inner surface of the main body 2 escapes the top surface 51 of the clamp fitting 5, so that the clamp fitting 5 is fully inserted into the insertion groove 54 around the axis of the hook bolt 8.
