Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a clamp and more particularly to a structural improvement of a clamp for the hose-clips which comprising a handle set, a flex, an actuator cable and a gripper device, the actuator cable may separate and engage with the gripper device in a simple manor through a pair of opening and an open notch built in the gripper device in order to meet the operation requirements. 
     In the pipe or hose design, e.g. the pneumatic or the oil pipe, often the pipes must connect to each other or to a designated hose-clip. Therefore all the connections between the pipes and the connectors must be tightly tied up by a hose-clip or pushed together to prevent loosen connection or unexpected leakage. However the terminal connectors may be well buried deeply in the complex the pipe layout or in restricted space. In order to reach it with the tools or hands, operators must depend on special tools to complete the work. 
     A mechanism of the clamp for the hose-clips designed to loose or install the pipes applies via a control cable between the clamp and the gripper set to loose up the pipes by the displacement of the control cable actuated by the clamp. 
     But the control cable and the gripper set are built as a whole piece. Depends on which kind of the gripper is attached, each of the clamp gives a specified operational function. In reality the pipes may disconnect from each other and from the connectors as well. Operator thus inconveniently has to carry several different kinds of the clamps in cases hand-unreachable locations are encountered. Thus an interchangeable the gripper set design would be practical. 
     In addition, there might not be sufficient working space for the gripper set once the gripper set reaches the pipe location. Operator has to maneuver the control cable in order to align the gripper set with the pipe. The cable is twisted and un-smooth accordingly. It thus degrades the capability of the cable in controlling the gripper set when operator applies maneuvering. The handle set easily yields unexpected attitudes due to the fixed configuration between the handle set and the control cable. It is hard for operator to the handle. The existing the clamp mechanisms are inaccurate and hard-to-handle under these conditions. It needs improvements. 
     The present invention is arisen to militate and/or obviate the aforediscussed disadvantage in order to provide a new and novel structure hereinafter. 
     SUMMARY OF THE PRESENT INVENTION 
     The present invention has a main object to provide a structural improvement of a clamp which includes a handles set, a flex, an actuator cable and a gripper device, a pair of openings and an open notch are built in the gripper device for the actuator cable interchanging, separation and adjoining. 
     Another object of the present invention is to provide a structural improvement of a clamp which provides an interchangeable integration among the flex, the actuator cable and the handle set, the handle set and the actuator cable maintain angular motion to each other and, thus, the actuator cable stays smooth and the handle set stays in operational attitude.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer to FIGS. 1,  2  and  3 , the present invention, a structural improvement of a clamp comprises a handle set  21  having a pair of handles  2  a gripper device  31  and an actuator cable  25  in a flex  24 . The handle  22  and an actuator  23  are at the two ends of the handle set  21  and act on each other, a blocker  26  is attached to the end of the actuator cable  25  which runs through the flex  24  fixed to the actuator  23 , the blocker  26  is restrained on a terminal piece  27  screwed at the forward end of a slider base  32 . 
     The gripper device  31  includes base  32  mounted with a spring  34  and a connected slider  33 , the sectional view of the slider base  32  appears in a U-shaped, a first opening  323  set for linking the slider base  32  is placed above a fastening hole  322  which locates at a forward end  321  of the slider base  32 , also there is a first protruding tab  324  at the outer side of the bottom. 
     A stopper  331  locates at the end of the slider  33 , a slider-fastening hole  332  appears at the stopper  331 , a second opening  333  connects to the slider-fastening hole  332 , there is also an open notch  334  on the surface of the slider  33  (as shown in the FIG. 2 of the slider), there is also a second protruding tab  335  placed at the bottom of the slider  33 . 
     According to the above, the fastening hole  322  at the end of the gripper device  31  on the slider base  32  restrains the position of the blocker  26  at the terminal end of the actuator cable  25  of the handle set  21 , the actuator cable  25  runs through the slider fastening hole  332  on the stopper  331  of the slider  33 . It tightly attaches the flex  24  to the slider-fastening hole  332 , and thus places the second protruding tab  335  on the slider  33  and the first protruding tab  324  on the handle set  32  against each other. The actuator cable  25  is actuated by the actuator  23  while the handle  22  on the handle set  21  is pushed. The slider  23  slides on the slider base  32  and there is a relative displacement between the second protruding tab  335  and the first protruding tab  324 . 
     The actuator cable  25  may easily travel through the first opening  323  on the fastening hole  322 , the open notch  334  on the slider  33  and the second opening  333  on the slider-fastening hole  332 . Thus it helps to integrate the actuator cable  25 , the slider base  32  and the slider  33  together. 
     In operating of the present invention, applying the second protruding tab  335  and the first protruding tab  324  on a pipe or a hose, the pipe is loosened due to the relative displacement and resultant force between the second protruding tab  335  and the first protruding tab  324 . 
     Please also refer to FIG. 4 for the second embodiment of the present invention. The gripper device  31  is attached to the slider base  32  through the slider  33 . There is the fastening hole  322  and the first opening  323  on the foward end  321  of the slider base  32 . The first protruding tab  324  is attached to the bottom of the slider base  32 . Also the open notch  334 , the stopper  331 , the fastening hole  322 , the second opening  333  and the second protruding tab  335  are built into the slider  33 , the first protruding tab  324  and the second protruding tab  335  are dentate. A pair of concave notches  325  and  336  are on each one of them. 
     Refer to FIG. 5 for the second embodiment of the present invention. The blocker  26  at one end of the actuator cable  25  is attached to the fastening hole  322  of the slider  33 . The other end of the actuator cable  25  runs through the slider-fastening hole  332  of the slider base  32 . It attaches to the handle set  21  and the first protruding tab  324  and the second protruding tab  335  at their locations on pipe. Held by the notches  325  and  336  of the first protruding tab  324  and the second protruding tab  335 , the cable maneuvering generates displacement and force between the first protruding tab  324  and the second protruding tab  335 , and thus detaches the connected pipe. 
     It is worthy of mentioning that different kinds of the gripper device  31  may conveniently be attached or disengaged from the actuator cable  25  due to the first and second openings  323  and  333  and the open notch  334  designed for the actuator cable  25 , the slider base  32  and the slider  33 . Operator may conveniently replace different kinds of the gripper device  31  for various pipes. 
     The handle set  21  and the flex  24  are linked but not fixed, the handle set  21  and the flex  24  may rotate with respect to each other. When the gripper device  31  enters an hand-unreachable working space (e.g. automobile engine combustion chamber), the twisted the flex  24  on the gripper device  31  may yield impaired the actuator cable  25  or poor handling attitude of the handle set  21 . With the help of the rotation flexibility between the handle set  21  and the flex  24 , it may be used to adjust the twisted the actuator cable  25  and the poor attitude of the handle set  31 . 
     In general this invention adopts handle set, gripper device, flex and actuator cable to implement pipe clamp. By the designated openings and open notch on gripper device, the actuator cable may quickly separate from and attach to different kinds of gripper device. It also maintains a smooth actuator cable and excellent handle attitude of handle set. 
     Note that the specification relating to the above embodiments should be construed as exemplary rather than as limitative of the present invention, with many variations and modifications being readily attainable by a person of average skill in the art without departing from the spirit or scope thereof as defined by the appended claims and their legal equivalents.
