In this clamping rod T, the adhesive part 8 is slightly longer than the length of the bottom surface of the clamping base 2, and is formed along this length, and is approximately perpendicular to the adhesive part 8 at both ends thereof. The locking portion 10 provided in this manner first has the locking groove 4
The stage is extended with a length corresponding to the length of the clamping base 2, and then a part of approximately the same length is curved and extended so as to slightly widen the width outward, thereby allowing the clamping base 2 to be freely inserted into and removed from the stage. Part 10
A is formed.

A pair of support arms 9 further extending from each of the locking parts 10 are connected to the clamping base 2 and the handle rod so that the adhesive part 8 can be pressed against the bottom surface of the clamping base 2 with the required pressing force. A circular curved portion 11 shaped like a screw coil spring is provided at the longitudinal center of the curved along P.
It is formed by bending it to impart elasticity.

Of the clamping rod 7 formed in this way, the adhesive part 8 is disposed in the clamping groove 3, the locking part 10 is disposed in the locking groove 4 so as to be freely engageable, and the support part 9 The open end 12 of the supporting arm 9 is rotatably engaged with the engaging portion 13 of the operation fitting 1.

Next, to explain how to use this, the operation fitting 1 in the tightened state is released, and the adhesive part 8 of the clamping rod 7 interlocked with the clamping rod 7 is inserted between the bottom surface of the clamping base 2 as shown in FIG. After creating a gap as shown in FIG. 3, the clamping rod 7 is inserted into the clamping base from the stepped portion 10A which is curved outward so that the locking portion 10 of the clamping rod 7 is slightly widened. At the same time as it is removed from the stand 2, the clamping rod 7 is rotated around the engaging part 13 of the operating fitting 1, and then the mopping thread M is attached to the adhesive part 8.

After attaching the motsu thread body M in this manner, the clamping portion 8 is attached to the clamping groove 3 on the bottom of the clamping base 2, and the locking portion is attached to the locking groove 4 on both sides of the clamping base 2. 10 respectively, and push down the operating fitting 1 in the open and relaxed state in the opposite direction to bring it into the tightened state.

In this way, a strong elastic force will be applied to the adhesive part 8 due to the elastic force of the support arm part 9 in which the circular curved part 11 in the form of a screw coil spring is bent in advance as shown in the figure. The mop thread body M is also securely clamped and fixed, and furthermore, the clamping groove 3 and the locking groove 4 prevent the clamping rod 7 from coming off.

After use, by operating the operation fitting 1 to release the tightened state, the adhesive part 8 of the clamping rod 7 that is linked to this can also be loosely fitted, so that the adhesive part 8 can be removed very easily. can be done.
