Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a hand tool, more particularly to a clamp having a clamping wire set for extending the distance between the handle and the working end of the tool, so that the working end can be extended into the engine chamber of a car or a small narrow space of other machineries for the application of the tool.




2. Description of the Related Art




Various tools such as clamps, wrenches, and the like are used for repairing machineries, and there are lots of wirings and components in the interior of ordinary machines or car engine chamber. Therefore, there are limitations for using ordinary tools in such a limited working space, not only staining the sleeve or clothes by dirty grease, but also having the risk of hurting the user's hand by the mechanical components. Furthermore, some of the repairing position is beyond the reach by the user's hands or hand tools. Therefore, the parts other than those requiring repair are removed first before repairing, and reinstall those parts after the repair is completed. In some cases, we have to disassemble and then assemble the whole set of machine for replacing or adjusting a small part, not only wasting efforts but also wasting lots of time.




SUMMARY OF THE INVENTION




The primary objective of the present invention is to provide a clamp assembly that can be extended into an engine chamber of a car or a small narrow space of other machineries for the application of the tool. The clamp assembly of the present invention can use a clipping member to clip a workpiece, or uses a poling member to poke the objects around the repairing workpiece, which offers a convenient, handy, easy, and convenient way for the repair.




Another objective of the present invention is to provide a clamp assembly that allows users to replace or install the clipping member or poking member on the same clamp handle.




A further objective of the present invention is to provide a clamp assembly having a replaceable clipping member and poking member, so that any single component of the clipping member or the poking member can be replaced when it is damaged. The structural design of the present invention enables users to replace such component quickly and easily.




To accomplish the foregoing objectives, the present invention comprises a pair of clamp handles, wherein one clamp handle has a sliding track, and said sliding track is pivotally couple to a corner of a clamp wire control plate, and both ends of said clamp wire control plate individually coupled to a clamp wire fixing member and pivotally coupled to another clamp handle; a pair of clamp heads are stacked and pivotally coupled with each other, and their rear ends are couple with said clamp handles. A clamp handle torque spring is disposed on one of the clamp head, and a clamp control plate is disposed on another clamp head, and the clamp control plate and the clamp head having a clamp handle torque spring at their corresponding edges each has a ratcheted edge and a ratcheted section engaged with each other. The rear end of the clamp control plate is a poking plate, and the ratcheted edge and ratcheted serration will be separated by pressing the poking plate, and the clamp wire fixing member is coupled with the rear end of the central linear member of a clamp wire set, and the central linear member passes through a protective tube, and its front end is coupled to a clipping member or a poking member. Controlling the extension or contraction of the central linear member of the clamp wire set produces an axial movement and further controls such clipping member or poking member to clip the workpiece or poke the objects around the workpiece.











To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.

After knowing the structure of the present invention, we will further describe the operation and movement of the present invention as follows:




The user generally operates the first and second clamp handles


10


,


11


to attain the purpose of controlling the opening of the clipping member


80


or the poking member


90


; the clipping member is closed to clip a workpiece and opened to release a workpiece; the poking member is opened to poke the objects surrounding a workpiece.




In

FIG. 5B

, the user exerts forces on the first and second clamp handles


10


,


11


by gripping them, the ratcheted section


43


of the second clamp head


41


and the ratcheted edge


63


of the clamp control plate


60


produces a alternate ratchet phenomenon and sound due to the sliding in the positive direction, and the clamp wire control plate


30


swings towards the second clamp handle


11


by sing the pivotal member


311


of its long arm


31


as a hinge, and such swing converts into a force on the sliding wedge


34


to drive the corner of the clamp wire control plate


30


to move towards the end of said sliding hole


23


, and said clamp wire fixing member also moves back and further pull the central linear member


71


. The front end of the central linear member


71


pulls the second clipping member


83


of the clipping member


80


, and the first and second clipping members


82


,


83


use said sliding space


822


to produce the corresponding movement and compress the spring


84


to achieve the control of clipping the workpiece. In

FIG. 8B

, if the first and second clamp handles


10


,


11


work with the poking member


90


, then the central linear member


71


is pulled while the first poking plate


92


is pulled so that the first and second poking plates


92


,


93


are separated to achieve the purpose of poking the objects surrounding the workpiece.




When the clipping member


80


has clipped the workpiece or the poking member


90


has poked the object to a predetermined distance, the user can gently grip the first and second clamp handles


10


,


11


. Although a tension is exerted on the first and second clamp handles


10


,


11


, the reaction on the ratchet section


43


and the ratcheted edge


63


of the first and second clamp heads


40


,


41


is in a latch situation in the opposite direction, therefore the first and second clamp handles


10


,


11


will be fixed in a predetermined clamping angle without the risk of spring apart.




In

FIGS. 5A and 8A

, if the user wants to release the workpiece from the clipping member


80


or the object around the workpiece from the poking member


90


, the user must press the poking plate


64


of the clamp control plate


60


in the direction towards the first clamp handle


10


so that the ratcheted edge and the ratcheted section


43


are separated, and the first and second clamp handles


10


,


11


lose the latching force. The clamp handle torque spring


50


and the spring


84


,


94


of the clipping member


80


or poking member


90


also lose the coiling or compression, both restore their positions. Particularly, the spring


84


,


90


of the clipping member


80


or the poking member


90


restores its position to drive the second clipping member


83


or the first poking plate


92


to restore the position such that the clipping member


80


or the poking member


90


restores its original opening status while pulling the central linear member


71


to move forward. The central linear member


71


also pulls the clamp fixing member


35


to use the sliding wedge


34


at its corner to move to the front of the sliding hole


23


such that the clamp control plate swings outward in the direction towards the first clamp handle


10


, and the first and second clamp handles


10


,


11


will automatically open.




The present invention uses a clamp wire set


70


to extend the distance between the handle of the tool to the working end, so that the tool can be extended into a small narrow operating space that the user's hand or regular tools cannot reach. The flexibility of the clamp wire set


70


allows the tool of the present invention to pass through the curve and turning in the space easily. The user can control the grip of the first and second clamp handles


10


,


11


to control the clipping member


80


to clip the workpiece or the poking member


90


to poke the objects around the workpiece. The operation is simple and handy. If the user wants to release the workpiece, the user just needs to press the poking plate


64


to open the first and second clamp handles


10


,


11


while restoring the clipping member


80


or poling member to the original opening status. The operation is also simple, handy, easy and convenient.




In addition, the clipping member


80


and poking member


90


of the present invention can work together with a clamp wire set


70


and uses the threaded fixture


721


of the protective sleeve


72


to couple with the threaded hole


4541


of the clamp wire plate


711


, and the threaded fixture


711


of the central linear member


71


to couple with the threaded hole


351


of the clamp wire fixing member


35


to quickly install the clipping member


80


or the poking member


90


on the same clamp handle. The clipping member


80


and the poking member


90


are the replaceable components. When a component fails, it can be replaced. For replacing a component, the C-shape latch ring


821


,


911


and the fixture


831


,


931


are removed to release the coupling of the components, and thus achieving the purpose of replacing components quickly.




While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
