The alignment and the line τ are in the first step. The end 1231 takes a length 11 which causes the ^121211 and the second pulling edge 1221 to be at the end of the opening 123 at either end angle (a/b/c/_) of the bottom 20, the 1212/1299^ 11 and the second pulling edge 1221 toward the opening 123 edge = d 与 and the nut 2 〇 either end angle (-c / d / e / f) tolerance difference between the upper and lower jumps of the length L1 The first-pushing first first pulling edge 1221 is connected to the bottom end 1231 of the opening ι23 at t 6 201219161 In order to form the larger corners A1 and A2, the corners A1 and A2 are formed in the direction perpendicular to the first side 1211 and the second pulling edge 1221 and the periphery of the first latching portion 121 and the second latching portion 122. The thickness of the H1 and the thickness of the first clamping edge 1211 and the second clamping edge 1221 are the maximum thickness distance from the periphery of the first clamping portion 121 and the second clamping portion 122. The lengths of H1 and H2 are limited to 35% of the width of the two opposite parallel sides of the periphery of the nut 20, and the manufacturing tolerance is limited to 35% of the width w =, and the length L1 is at the alignment line T The intersection position of the opening 123 on the center vertical line to the position where the first latching portion 121 and the second latching portion 122 are coupled to the bottom end 1231 has a length L2 which is 6 (10) of the length L1, and the length L2 manufacturing tolerance Restricted to be less than 15% of the length of the length L1 of 6〇%. Referring to FIG. 3, another embodiment of the present invention shows that the opening structure 1〇 of the present invention passes through the L1/L2/H1. /H2 set the length of each position, knowing that under the premise of taking into account the structural strength and weight reduction, it can be smaller.

The rotation above the angle causes the operator to again disengage from the nut 2 to the other rotational position in the same holding direction for the next 1/6 rotation, and continue to continue, compared to the ratio of the conventional structure. The length of the L1 is such that the end edges 1212/1222 of the first latching portion 121 and the second latching portion 122 are positioned at either end of the nut 20 during operation (a/b/). The angular end of c/d/e/f) is parallel to any of the contact nuts 20 of the design that is provided with a sufficient contact area to provide a first contact edge 1211 and a second trigger edge 1221. When the rotation is not performed, the conduction force is degraded, and the length of the L2 is set to relatively reduce the volume of the second half of the torsion portion 12, and the maximum thickness of the periphery of the first and second latching portions 121 and 122 is opposite. The homeopathic reduction is made closer to the aforementioned m/H2 length, and sufficient structural strength is maintained, and the first yoke portion cl and the first ferrule portion 122 are formed by a general open-end wrench. The position of L2 is based on the structural strength 201219161. Its peripheral design is an outward expansion of the arc and slightly larger than the HI /Ή After 2 degrees, it will be retracted by a larger arc after a certain distance.
