Detailed Description

It is noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present application, where the contrary is not intended, the use of directional words such as "upper, lower, top and bottom" is generally with respect to the orientation shown in the drawings, or with respect to the component itself in the vertical, perpendicular or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 2, 3 and 4, an anti-misoperation universal rotary switch includes a head knob 10, an outer cylinder 20, a positioning button 30, a spring 40, a spring fixing seat 50, a tightening sleeve 60 and a coupling 70. There is the hole 101 of stepping down in one side of head knob 10, and there is inside fixed column 102 at the center, there is spring mounting hole 301 positioning button 30 one side, and there is boss 302 in one side in addition, spring 40 one end is installed on spring fixing base 50, other one end is fixed in spring mounting hole 301, spring fixing base 50 is fixed on the inside fixed column 102 of head knob 10, boss 302 is installed in the hole 101 of stepping down. The head knob 10 is mounted on the outer cylinder 20, the tightening sleeve 60 is mounted in the inner fixing post 102, the coupling 70 is mounted in the tightening sleeve 60, and the tightening sleeve 60 and the coupling 70 are fixed together on the inner fixing post 102 by screws. When the operator manually pushes the boss 302 of the positioning button 30 toward the inside of the head knob 10, the spring 40 is compressed, and the head knob 10 can freely rotate around the outer cylinder 20, and the coupling 70 is driven to rotate together by the tightening sleeve 60.

Simultaneously, positioning button 30 contains reference column A303 reference column B304, there are location bayonet socket A201 and location bayonet socket B202 on the urceolus 20, location bayonet socket A201 is unanimous with location bayonet socket B202's size, reference column A303 can smoothly get into location bayonet socket A201 in, and the cooperation is inseparable, reference column A303 can smoothly get into location bayonet socket B202 in, and the cooperation is inseparable, during reference column A303 got into location bayonet socket A201 or location bayonet socket B202, reference column B304 closely laminated with the inside wall of head knob 10. Therefore, when the operator loosens the boss 302 of the positioning button 30 and continues to rotate the head knob 10, when the positioning column a303 rotates to the position of the positioning bayonet a201 or the positioning bayonet B202, because the elastic force generated when the spring 40 recovers and the positioning column B304 are blocked by the inner side of the head knob 10, the positioning column a303 is pushed into the positioning bayonet a201 or the positioning bayonet B202 by the spring 40, and at this time, the head knob 10 can not continue to rotate any more, so that the misoperation caused by the head knob 10 rotating over the head can be avoided.

The above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
