TWISTING ROLLER WITH A LOCKING AND CUTTING MECHANISM FOR WIRE ENDS
The present invention provides an improved twisting roller with a wire ends locking and cutting mechanism. The twisting roller includes a spool, a baffle plate at both ends, and a housing externally on the twisting roller. The locking groove and cutting groove are assembled onto the baffle plate of the twisting roller or hanging piece of the housing. A cutter is assembled into the cutting groove. The wires can be pulled through the locking groove and cutting groove for direct cutting. After the wires are cut, the wire ends are locked securely into the locking groove, and a portion is exposed for convenient operation and fixation with improved applicability.

BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to a twisting roller, and more particularly to an innovative roller which allows a locking groove and cutting groove to be assembled onto the baffle plate or housing for cutting and fixing wires.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.
The twisting roller of the present invention is an auxiliary tool that is widely applied to the construction and decoration industry. It generally has a circular shaft with expanded plate at both ends, where a ring groove for reeling of wires is defined externally onto the circular shaft. When the existing twisting roller is employed, the operators shall pull out the wires to a predefined length, then cut the wires with tools, pliers or burn out the wires with a cigarette lighter. However, when the twisting roller is applied to a flat location for horizontal or vertical measurement, the operators are often positioned on the scaffold or at dangerous site, and have to manually grasp the wires on the twisting roller while using pliers or lighters. In such case, there is the danger that operators may lose their balance. From another viewpoint, given the fact that the wires on twisting roller are made of flexible materials, the workers may find it difficult to cut off the wires with commonly used pliers. Also, the flame of the lighters may possibly be extinguished due to strong winds at the work site, leading to inconvenience and inapplicability.
Because there is no locking feature provided for the existing twisting roller and because the wires present excellent flexibility and sliding properties, the wire ends are possibly loosened, leading to inconvenient carrying and time-consuming rearrangement. Some users insert the wire ends into the winding wires, but find it difficult to search for them.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide an improved structure that can significantly improve efficacy.
Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
BRIEF SUMMARY OF THE INVENTIONThere is improved efficacy of the present invention.
Based upon innovative structures, the baffle plate or housing of the twisting roller is provided additionally with a locking groove and cutting groove. The wires can be pulled through the cutting groove of the shield for direct cutting. As such, the operators could rapidly finish the cutting action more efficiently and safely without the need of other tools or a cigarette lighter.
After the wires are cut, the wire ends are locked securely into the locking groove, and a portion is exposed for convenient operation and fixation.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
The baffle plate 13 of the twisting roller 10 is provided with a trough 14 for accommodating the cutter 20 and shield 30. As such, the cutter 20 and shield 30 present smoothness after assembly, meanwhile the cutter 20 is embedded (shown in
Furthermore, the baffle plate 13 of the twisting roller 10 is provided with a button 15, whilst assembly holes 22, 33 are placed opposite to the cutter 20 and shield 30. So, the cutter 20 and shield 30 are assembled and positioned on the baffle plate 13 of the twisting roller.
Referring to
The cutting and fixing methods and the operating principle of the second and third preferred embodiments are the same with the first one.
Claims
1. A twisting roller, comprising:
- a spool having wires would thereon;
- an expanded baffle plate at both ends of said spool;
- a cutter and a shield, assembled onto the baffle plate said cutter being assembled between the baffle plate and shield; and
- a locking groove and cutting groove, assembled separately at both ends of said shield, said cutter having a blade exposed to said cutting groove.
2. The roller defined in claim 1, wherein the baffle plate is provided with a trough for assembly of said cutter and said shield.
3. The roller defined in claim 1, wherein the baffle plate is provided with a button, and an assembly hole, said assembly hole being placed oppositely said cutter and said shield, said cutter and said shield being assembled and positioned onto the baffle plate.
4. A twisting roller, comprising:
- a spool, having wires would thereon;
- an expanded baffle plate at both ends of said spool;
- a housing, being assembled externally and having a hanging piece located on top of said housing; and
- a locking groove and cutting groove, assembled separately at both ends of said hanging piece, said cutter having a blade exposed to the cutting groove.
5. The roller defined in claim 4, wherein said housing is comprised of two semi-circular housings, said housing having an assembly surface with a button and locking hole arranged thereon.
6. The roller defined in claim 4, wherein said housing is of a single Π-shaped structure, said housing having a flexible clipping arm is extended towards a bottom of both ends of said housing, the clipping arm having an axle block is protruded at two ends thereof opposite to a center.
7. The roller defined in claim 4, further comprising:
- a recession placed laterally onto the cutting groove; and
- a positioning pin placed into said recession, enabling assembly and positioning with said cutter.
8. The roller defined in claim 4, wherein both ends of said housing have a convex portion, preventing wires from being trapped by said housing.
