With this configuration, the arm that is pressed by the cam when the lever is operated can press the upper chrysanthemum seat against the lower chrysanthemum seat and lock the handle well without causing rattling. When operated to release the pressure, the upper chrysanthemum seat can be moved upwardly away from the lower chrysanthemum seat, releasing the lock, and allowing the handle to be rotated in the desired direction around the spindle and locked. By adjusting the adjuster at the tip, you can make small adjustments to the pressing force and obtain an appropriate tightening force for the chrysanthemum seat surface.

An annular chrysanthemum seat 1 that can be engaged with the chrysanthemum seat 2 is integrally formed on the lower surface of a support plate 18 that is integrally fixed to the lower surface of the base a of the handle frame A. A vertical cylindrical body 1 that can be freely rotatably fitted to the upper part of the support shaft 3 is attached to the inner upper part of a.
9 are integrally fixed, a large horizontal hole 25 facing the horizontal hole 6 of the support shaft 3 is formed in the middle part of the cylinder 19, and both sides of the cylinder 19 are extended in the front-rear direction. The rear part of the planar U-shaped arm 5 is attached to the support plate 1.
The shaft rod 2 inserted into the rear upper bracket 20 of 8
1, and one end 21a of the shaft 21 is provided to protrude outward from the base a. An adjuster star 4 made of a bolt whose lower end can abut against the upper surface of the support plate 18 is vertically screwed into the front part 5a of the arm 5, and a lock nut 4a is screwed into the lower part of the adjuster star 4, and a lock nut 4a is screwed into the lower part of the adjuster star 4. A cover 23, which can be attached and detached using screws 22, is attached to the upper part of the distal end side of the base part a, thereby forming an adjuster star part.

A compression spring type elastic device 10 is interposed between the upper end of the support shaft 3 and the inner surface of the base a inside the upper part of the cylinder body 19, and is inserted into the horizontal hole 6 of the support shaft 3 and the inside of the cylinder body 19. A horizontal rotating shaft 8 that is loosely fitted into the horizontal hole 25 is freely rotatably inserted into the intermediate portion of the arm 5 in the front-rear direction, and is mounted as a shaft. A cam 9 that can be pressed against the inner upper surface of the horizontal hole 6 is integrally formed, and an end 8a of the rotating shaft 8 protruding outward from the base a has a cam 9 that can be rotated to one side when locked.
One end 21a of the shaft rod 21 is located at a portion slightly beyond the maximum pressure point of the cam 9, and the base of the lever 7 is fixedly attached so as to come into contact with this end 21a.

Therefore, when the handle is locked, the cam 9 of the rotating shaft 8, which is rotated by the lever 7 that has been rotated until it abuts one end 21a of the shaft rod 21, locks the cam 9 of the support shaft 3, as shown in each figure. The arm 5 is pressed down while being in pressure contact with the upper surface of the horizontal hole 6, and in this state, the lower end of the adjuster star 4 presses the support plate 18 downward, causing the upper chrysanthemum seat 1 to be moved against the lower chrysanthemum seat 2. This means that they can be firmly interlocked without any looseness.

In addition, when changing the handle in the front-back direction, when the lever 7 is rotated in the direction of arrow (A), the cam 9 rotated by the rotating shaft 8 is rotated downward, and the cam 9 is rotated downward, so that the lever 7 is rotated in the direction of the arrow (A). The downward pressure can be released, and in this state, the base part a will float due to the elastic force of the ammunition 10, and the upper chrysanthemum seat 1 will float away upward from the lower chrysanthemum seat 2, Handle frame A as is
When the lever 7 is rotated in a desired direction about the support shaft 3 and the lever 7 is rotated at that position, the handle can be locked as described above.

If the cam 9 is worn or if there is play in the engagement between the chrysanthemum seats 1 and 2, remove the screws 22, remove the cover 23, and insert the adjuster star 4 from the outside.
By operating the lock nut 4a and adjusting the adjuster star 4 forward or backward, adjustment can be made to ensure the tightening force.

In addition, if the cam 9 is worn or looseness occurs in the meshing of the chrysanthemum seats 1 and 2, a reliable tightening force can be easily obtained by simply adjusting the adjuster star 4 on one end of the arm 5. It has the advantage of having a simple structure and being able to be suitably implemented.
