1. Field of the Invention
The present invention relates in general to an adjustable riveter apparatus for pulling screw column, and more particularly, to control a length of the screw column for different screws.
2. Description of the Related Art
The riveter apparatus is a very common tool in construction site for pulling screw column. The riveter apparatus make a position head from pulling a plate, than use a column to connect to front end of a rod of riveter apparatus, and the riveter apparatus through a hole on a board. While pressing a handle of riveter apparatus, the rod will back and change the column shape so as to fix on the board. The changed column is made from the rod dragging force and the column backing force, so the distance of dragging relative to quality of riveter apparatus. Further, the rod dragging force too big to over the distance of column need, the column will be destroyed under the handle pressing force and affect the quality of construction. It's also have problem, while the rod dragging force too small to change the column, the column is not effectiveness. In the past, the riveter apparatus can not be adjust distance, so the column must to be keeping changed by pressing the handle of riveter apparatus until the optimal distance formed. It makes the column to be destroyed easily, and should be rework. In order to solve the above problem and save working time, the present invention provides an adjustable riveter apparatus for adjusting the distance of the column so as to improve the quality of construction and prevent the column to be destroyed.
It is an object of this invention to provide a riveter apparatus for adjusting the skew column and easy controlling the pulling force. Further, to achieve high quality construction.
It is another object of this invention to provide a riveter apparatus for adapting different construction sits to prevent the column thread to be destroyed. To make skew column with the riveter apparatus of present invention is more convenient and efficient.
It is still another object of this invention to provide a riveter apparatus for adjusting the fine skew column. It can be more precise to control the column distance to form.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

The holding part includes a pair of outside-arms 31, inside-arms 32, handles 33 and push arms 34. The outside-arms 31 connect to two side of the body 11 respectively. The inside-arms 32 connect to the end of outside-arms 31 respectively, and the push-arms 34 connect to the end of inside-arm 32. Each of portions of the holding part can link together to move. Furthermore, perforation 35 is formed in the middle of the push-arms 34.
The pulling part 50 is through inside the base 11 and front tube 12 of the body 10, the pulling part 50 includes an adjustable nut 51, an adjustable rod 53. The adjustable nut 51 is position on the adjustable groove 14 of the column 13. Outside the column, there is a notch 511 as

Next, with reference to
The opposite site of screw tube 75 and riveter is screw rod 751. The rod 53 in the front end of pulling part 751 is constructed with an inner screw section. By connected this inner screw section 533 and the screw rod 751 in the front end of screw tube 75, we can proceed the riveter process and then make the distortion 752 of screw tube 75.
As we mention above, this invention is about the design of adjustment of adjustable nut 51 and screw connection of adjustable nut with the adjustable shaft 52 in pulling part 50. If we adjusted the screw cap 51, we can make the lateral motion by cross-linked reaction of pulling part 50. And then we can improve the quality of riveter process by the adjustment of pulling force and moment. And we have fine scale apparatus on the adjustable nut 51. We can accurately control the adjustment by adjusting the moving quantities read out by the scale apparatus. Finally, we cab obtain accurate operation and quality of pulling cap.
The invention thus has the advantage that the scan mode is automatically determined. The user does not have to judge the correct scan mode of the scanner by himself/herself.
Another embodiments of the invention will appear to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples to be considered as exemplary only, with a true scope and spirit of the invention being indicated by the following claims.
