SAFETY DEVICE FOR TOGGLE CLAMPS
A safety device for toggle clamps is disclosed. The safety device of the present invention comprises a seat portion, a fixing portion, a position-limiting portion, a pull portion and a retaining piece. The fixing portion and the pull portion are connected with the seat portion. The position-limiting portion connects the fixing portion with the pull portion. A positioning hole is provided by either connective juncture of the position-limiting portion, and another positioning hole is provided by either protrusion. To affix the pull portion, we can insert the two insertion ends of the retaining piece into the two positioning holes of the pull portion and the two positioning holes of the position-limiting portion. In addition, a positioning piece may affix an object so that a user may work on the object.
1. Field of the Invention
The invention generally relates to a safety device for toggle clamps. More particularly, the invention relates to a safety device that can secure the fixing or retaining of the relevant components of a toggle clamp to avoid hazards and bodily injuries.
2. Description of the Prior Art
As of now, a connective piece is usually used in the toggle clamps for clamping. Hinges are usually used to connect components, such as the pull portion, insertion ends and position-limiting portion. Therefore, the components are not completely affixed; especially, when the connective piece is used vertically, some of the components can still move. In addition, the toggle clamps of the prior art are structurally complicated and have a higher cost of production. These drawbacks need to be improved.
From the above, we can see that the toggle clamps of the prior art have disadvantages and need to be improved.
To eliminate the disadvantages of the toggle clamps of the prior art, the inventor has put a lot of effort into the subject and has successfully come up with the safety device of the present invention.
SUMMARY OF THE INVENTIONAn object of the present invention is to provide a safety device that can secure the fixing of the relevant components of a toggle clamp to avoid hazards and bodily injuries. Therefore, safety may be assured.
Another object of the present invention is to provide a safety device that is structurally simple and easy to use and has a low cost of production.
To reach these objects, the safety device of the present invention is disclosed. The safety device of the present invention comprises a seat portion, a fixing portion, a position-limiting portion, a pull portion and a retaining piece. The fixing portion and the pull portion are connected with the seat portion. The position-limiting portion connects the fixing portion with the pull portion. A positioning hole is provided by either connective juncture of the position-limiting portion, and another positioning hole is provided by either protrusion. To affix the pull portion, we can insert the two insertion ends of the retaining piece into the two positioning holes of the pull portion and the two positioning holes of the position-limiting portion. In addition, a positioning piece may affix an object so that a user may work on the object.
These features and advantages of the present invention will be fully understood and appreciated from the following detailed description of the accompanying Drawings.
