PROBLEM TO BE SOLVED: To provide a connection tool for connecting and disconnecting rod members by a single operation without any rotation between the rod members connected in use.SOLUTION: A connection tool is constructed to include a first tool or a roller side member 11 and a second tool or a long-handled member 12, which is composed of an axially stationary portion 13, a locking operation portion 14 and a fastener 15. A cylindrical portion 13b is inserted into a circular hole portion 14b, and the fastener 15 is so fixed in a groove portion 13e as not to come out in the longitudinal direction. While a cylindrical portion 13a being inserted into a reception portion 11d, a locking protrusion 11f is inserted into the guide groove of the locking operation portion 14, and this locking operation portion 14 is turned to position the locking protrusion 11f in the lock groove portion, so that the long-handled member 12 and the roller side member 11 are connected and locked. In this state, the roller side member 11 and the axially stationary portion 13 are irrotationally connected by the fitting of the reception portion 11d and the cylindrical portion 13a, so that they are prevented from slip-out by the lock of the lock protrusion 11f in the locking operation portion 14. |
