[0070] For further information, see Fig.16 , the angle α between the unlocking surface 2621 and the locking surface 2622 is 80°~90°. It can be understood that if the angle α is too large, it is easy to cause the locking surface 2622 to rebound after abutting against the connecting plate 216, affecting the locking effect of the locking surface 2622 on the connecting plate 216; if the angle α is too small, it will increase the difficulty of rotating the rotating block 262. After many tests, the angle α is within the range of 80°~90°, which can be compatible with the locking effect of the locking surface 2622 and the rotation of the rotating block 262. Those skilled in the art can specifically set the angle α to 80°, 85°, 90°, etc., which is not limited here. In this embodiment, preferably, the angle α is 88°.

[0071] The arc radius R of the transition surface 2623 is 3.7mm to 4.2mm. It can be understood that if the radius R is too large, it is easy to cause the locking surface 2622 to rebound after abutting against the connecting plate 216, affecting the locking effect of the locking surface 2622 on the connecting plate 216; if the radius R is too small, it will increase the difficulty of rotating the rotating block 262. After many tests, the radius R is in the range of 3.7mm to 4.2mm, which is compatible with the locking effect of the locking surface 2622 and the rotation of the rotating block 262. Those skilled in the art can specifically set the radius R to 3.7mm, 3.8mm, 3.9mm, 4.0mm, 4.1mm, 4.2mm, etc., which is not limited here. In this embodiment, preferably, the radius R is 4.0mm.

The stop protrusion 132 is inclined downward from one end close to the positioning boss 12 and is provided with a stop slope 1321 with an inclination angle of 0° to 5°. The stop slope 1321 is used to prevent the operating handle 26 from moving away from the positioning boss 12 when the positioning seat 21 is locked. The inclination angle of the stop slope 1321 refers to the angle β between the stop slope and the horizontal plane. In this embodiment, the angle β is 1.5°, and the height difference between the highest point and the lowest point of the stop protrusion 132 protruding downward is 1.3 mm.

[0075] Furthermore, a stop block 29 is sleeved on the connecting rod 27, the upper end of the stop block 29 abuts against the stop slope 1321, and the lower end of the stop block 29 abuts against the second spring 28, and the two ends of the second spring 28 respectively abut against the stop block 29 and the locking block 22.
