Adopt above-mentioned setting, when first spacing portion and sincere son cooperation butt were spacing, its first straight-line section, second straightway, first kink homoenergetic leveled the contact with sincere son, stability when improving the cooperation, the setting of third straightway also can improve the stability with the lateral margin contact of sincere son, provides pivoted elastic force for sincere son.
Further, the distance between the farthest end of the second contact end relative to the base hole center and the base hole center is smaller than the distance between the farthest end of the first contact end relative to the base hole center and the base hole center.
By adopting the arrangement, on the premise of relative positions among the first protruding shaft, the second protruding shaft and the mechanism side plate of the existing product, the possibility of interference between the second contact end and the handle can be reduced only by slightly changing the torsion spring part.
Further, the second contact end is formed by a fourth straight line segment.
By adopting the arrangement, the second contact end is formed by the fourth straight line segment, so that bending is not needed, and the processing is convenient.
Furthermore, a ring groove for embedding the fourth straight line section is formed in the first protruding shaft.
By adopting the arrangement, the matching effect between the first protruding shaft and the second abutting end can be improved, and the second abutting end is prevented from being dislocated from the first protruding shaft and falling out.
