Caulking Assisting Device
First Claim
1. A caulking assisting device comprising:
- a fixed frame having a fixed plate and a pair of extended side plates, the fixed plate being used for affixing a filler coating-supplying device, each extended side plate comprising a first pin connection part, a second pin connection part, a first limiting recess and a second limiting recess, the first pin connection part located at an end of the respective extended side plate;
a rolling part rotatably connected to the first pin connection part on the pair of extended side plates, and extending from a bottom edge of the pair of extended side plates;
a movable frame having a pair of extended parts, an accommodating space, a pair of through holes and a pivotal part, a tapered roller rotatably connected to an end of the pair of extended parts, a diameter of the tapered roller tapering toward opposing sides, the pair of through holes are respectively disposed on opposite sides of the movable frame, the pivotal part pivoted to the second pin connection part on the pair of extended side plates, such that the movable frame is disposed between the pair of extended side plates and is rotatable axially about the second pin connection part, thereby enabling the tapered roller to have at least a use position and a non-use position; and
an elastic element disposed in the accommodating space of the movable frame, with a respective positioning protrusion on opposite ends, and the positioning protrusions are respectively capable of being placed in the pair of through holes;
wherein the elastic element elastically biases the positioning protrusions to partially pass through the pair of through holes to selectively lock the pair of through holes to either the first limiting recesses or the second limiting recesses, and limiting rotation of the movable frame;
when a lateral pressure greater than an elastic force of the elastic element is exerted on the positioning protrusions, the positioning protrusions are pushed from either the first limiting recesses or the second limiting recesses and enter the through holes, such that the movable frame can rotate axially about the second pin connection part; and
when the positioning protrusions are slotted to the first limiting recesses, the tapered roller is in the use position, and when the positing protrusions are slotted to the second limiting recesses, the tapered roller is in the non-use position.

Abstract
A caulking assisting device has of a fixed frame mounted to a filler coating-supplying device, a rolling part mounted to the fixed frame, a movable frame and an elastic element. The positioning frame has a pair of first limiting recesses and a pair of second limiting recesses. The movable frame is pivoted to the fixed frame and is rotatable, and a tapered roller is pivoted at the end of the movable frame. Meanwhile, the elastic element is disposed on the movable frame, while a positioning protrusion is located at both ends respectively. As a result, the tapered roller can be moved to a use position and a non-use position by the rotation of the movable frame, thereby switching between the rolling part and the tapered roller while in use.
