(Prior art and its problems) In the past, various locking mechanisms have been devised and implemented for handles such as kettles, but they tend to loosen due to vibration during operation, wear out with repeated use, etc., and have poor durability. In addition to this, there were other drawbacks such as the complicated structure and the large size of the locking mechanism of the handle.

本考案はこれらを解決すべくなされた。 The present invention was made to solve these problems.

(Means and actions for solving the problem) A movable element provided at the center of a spindle such as a Kotoku is pressed by rotating the handle of the Kotoku, and the movement of the movable element is controlled by a ball that creates friction on the outer periphery of the spindle. The lock is transmitted to the board and can be locked at any position on the handle.

In Figure 2, numeral 5 is a movable element that is installed so that the eccentric length of the handle can slide up and down, and its tip is tapered, and the tapered part has a guide hole cut at right angles to the spindle 2. It is in contact with the steel balls 6 (one pair) that have entered the .

In Figure 2, the handle 3 is in an unlocked state (non-fixed state), and by rotating the grip part of the handle to the right, the eccentricity e of the handle shown in Figure 2 will also move to the right, causing the movable member to move to the right. 5's head will be bowed down. The lowered movable element 5 pushes out the pair of steel balls 6 that are in contact with its lower end perpendicularly to the axial direction of the spindle 2, and forcefully presses them against the back surface of the friction plate 7. The spindle-2 can be locked (fixed) at any position.

(Effect of the invention) By operating the handle 3, the spindle 2 is rotated to open and close the ball valve 14, and
At any open/close position of the ball valve 14, the spindle 2 can be fixed to itself by rotating the handle 3 itself.

Since the friction plate 7 is pressed against the inner surface of the spindle hole of the Kotoku body 1 by the mover 5 and the steel ball 6, by selecting the material and hardness of these, it can be securely fixed and will not come loose due to vibration during operation. ,
There is almost no wear and tear, and the durability is sufficient for repeated use. The structure is simple and the handle locking mechanism is compact.
