The direction of the hour hand is contracted to a minimum extent, which in turn pushes the cylinder 34 on the left side of the lug 32, so that the bi-directional block 31 can be rotated counterclockwise. Similarly, when the user rotates the four fixing posts 36 on the turntable clockwise, the fixing post 36 pushes the cylinder 34 on the left side of the bump 32, so that the two-way block 31 can be rotated clockwise.

For the sake of the job, how to solve the problem that the fixed column needs to push the two control elements on the right side of the bump and the left side of the cylinder at the same time. After the inventor devoted himself to experiment, test and research, finally obtained a one-way transmission device, in addition to being effective. The ground allows the user to push only one control element, and also to avoid the effect of completely squeezing the spring to a minimum. That is, the problem to be solved by the present invention is how to overcome the problem that the spring is completely squeezed along the circumference, so that the torsion spring only needs to be partially compressed, and how to overcome the cylindrical control element is to press the spring along the circumference. The problem, and how to overcome the problem of fixing the column to push the two cylinders at the same time.

Referring to the seventh figure, it is shown that the one-way transmission 40 is in a static condition (ie, when the power is cut off or the motor is broken), and the axle 50 cannot rotate the two-way slider 52 counterclockwise by itself. After the backstop block 54 is first pushed by the first torsion spring 61 to a left contact point 71, the left counter stop block 54 abuts the top positioning ring 51 with an abutting radius UR (length 13.62 mm), and the axle 50 is pushed by a The radius PR (length 16 mm) pushes the left reverse block 54, the axis AC of one of the axles 50 and the left contact point 71 of the left counter block 54 (ie, the point where the left counter block 54 is tangent to the positioning ring 51, a pivoting position) forms a left radius of rotation (ie, the inner ring radius of the positioning ring 51, the length is 29.5 mm), and the sum of the abutting radius UR and the pushing radius PR (total length is 29.62 mm) is greater than the left radius of rotation Therefore, the axle 50 cannot rotate the two-way slider 52 to the left, and an angle (170°) is formed between the pushing radius PR and the abutting radius UR, and the extension line of the pushing radius PR and the abutting radius UR are The angle formed is 10°.

Therefore, when the axle 50 is to rotate counterclockwise by itself, the force is first transmitted to the pin 67 (the force applied by the axle 50 is here), and then the left counter block 54 is driven by the pin 67 because the inner ring The radius of 29.5 mm is smaller than the relationship between the yoke 50, the two-way slider 52 and the left counter block 54 having a total radius length of 29.62 mm. Therefore, the left counter block 54 interferes with the positioning ring 51 and cannot rotate by itself. The same is true when the axle 50 is to rotate clockwise by itself.
