Abstract

A sucking disc apparatus capable of detecting adhesive force comprises a rod body, a sucking disc at the rod body and corresponding to its slot, a pressing rod pivotally coupled to the slot or the sucking disc and turned with respect to the rod body and abutted at the sucking disc, an operating rod installed in a slide of the rod body and slid with respect to the slide, a first identification element installed in a containing space of the rod body by an axial shaft and having a first color corresponding to an opening of the rod body, and a second identification element coaxially and pivotally installed at the axial shaft and the operating rod and turned with respect to the first identification element and stacked onto the first identification element, and including a second color different from the first color and corresponding to the opening.

Claims

1. An improved sucking disc apparatus, capable of detecting an adhesive force, comprising:

a rod body, comprising at least one slot, at least one slide, at least one containing space, and at least one opening, wherein the slide, the containing space and the opening are interconnected with each other, and the slide has a flange protruded from the slide;

at least one sucking disc, installed at the rod body and corresponding to the slot, comprising a spring with both ends abutted at the sucking disc and the rod body respectively;

at least one pressing rod, pivotally coupled to either the slot or the sucking disc, turned with respect to the rod body and abutted at the sucking disc;

at least one operating rod, installed at the slide and slid with respect to the rod body, comprising a first end, a second end and a return spring, wherein the first end is protruded from the rod body, and the second end is protruded out from the containing space, and both ends of the return spring is abutted at the flange and the first end respectively;

at least one first identification element, comprising an axial shaft, wherein the first identification element is installed in the containing space by the axial shaft, and the first identification element further comprises a first color corresponding to he opening; and

at least one second identification element, coaxially and pivotally coupled at the axial shaft and the second end, wherein the second identification element is turned with respect to the first identification element and stacked onto the first identification element, and the second identification element comprises a second color corresponding to the opening, and the second color and the first color being different colors.

2. The sucking disc apparatus of claim 1, wherein the first end is sheathed into a sleeve, and the return spring abuts at the sleeve.

3. The sucking disc apparatus of in claim 1, wherein the second identification element is stacked onto the first identification element and disposed on the top of the first identification element.

4. The sucking disc apparatus of claim 1, wherein the first identification element is a fan-shape.

5. The sucking disc apparatus of claim 1, wherein the second identification element is an arc-shape.

6. The sucking disc apparatus of claim 1, wherein the second identification element is pivotally coupled to the second end by an axle.

7. The sucking disc apparatus of claim 1, wherein the pressing rod is pivotally coupled to either the slot or the sucking disc by an axle.

8. The sucking disc apparatus of claim 1, wherein the pressing rod comprises an operating portion.

9. The sucking disc apparatus of in claim 1, wherein the sucking disc comprises a protruding rod protruded out from the slot, and the pressing rod is pivotally coupled to the protruding rod.

10. The sucking disc apparatus of claim 9, wherein the spring is sheathed onto the protruding rod, and both ends of the spring are abutted at the sucking disc and the rod body respectively.
