Its further technical scheme is:
Described opening is U-shaped opening, and support plate is positioned at opening one side of U-shaped opening, and connecting plate is positioned at blind end one side of U-shaped opening, and two support plate symmetries are located on the base of U-shaped opening both sides, and two bearing pins are supported on respectively on two support plates.
On a support plate in described two support plates, by rotating shaft, be rotatably connected to baffle plate, baffle plate is provided with away from one end of rotating shaft the groove that Open Side Down, and another piece support plate in two support plates is provided with minor axis, and minor axis engages with the described groove of baffle plate.
The outside of described two jaws is equipped with limiting plate, and limiting plate is vertical with the rotate path of jaw
Technique effect of the present utility model:
The utility model stretches out the part shaft part of connecting plate by manually deviating from opposite directions or mutually rotary pin shaft, drive two jaw rotations, thereby realize the clamping of pipe fitting or unclamp; By the setting of the sector structure at jaw, and indent curved portions is set on the arch section of fan-shaped jaw, can realizes the pipe fitting of different tube diameters is clamped thus; By in the indent curved portions at jaw, tooth being set, can increase the frictional force between jaw and pipe fitting, increase the reliability of pipe fitting clamping; Opening is made as to U-shaped opening, and is provided with the sideboard that can open U-shaped opening between two support plates, can go out pipe fitting or the direction perpendicular to opening, pipe fitting be taken out from the opening of U-shaped opening one side-draw; By the setting of base and limiting plate, can control the rotating range of jaw.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
See Fig. 1, the utility model comprises base 1, the middle part of base 1 has the opening 2 for holding pipe fitting, on the base 1 of opening 2 both sides, be arranged with jaw 3, jaw 3 is fixedly supported on bearing pin 4, the two ends of bearing pin 4 are rotatably supported on respectively support plate 5, on connecting plate 6, support plate 5 and connecting plate 6 lay respectively at the both sides of opening 2, the part that bearing pin 4 stretches out support plate 5 is provided with radial opening pin 7, the length of split pin 7 exceeds the installing hole of bearing pin 4 on support plate 5, split pin 7 is for the axial location of bearing pin 4, the opposite side of bearing pin 4 stretches out connecting plate 6 and extends laterally, the axial end portion of described outward extending bearing pin 4 is as rotating handles, jaw 3 is sector structure, and the arch section of jaw 3 is indent curved portions 8, and the length direction along the described arch section of jaw 3 in indent curved portions 8 is provided with multiple teeth.
Further, in order to take out the side that facilitates pipe fitting shape base 1, described opening 2 is made as to U-shaped opening, support plate 5 is positioned at opening one side of U-shaped opening 2, connecting plate 6 is positioned at blind end one side of U-shaped opening 2, two support plate 5 symmetries are located on the base 1 of U-shaped opening 2 both sides, and two bearing pins 4 are supported on respectively on two support plates 5.
Further, without taking out during pipe fitting from base 1 side, in order to prevent from unclamping after jaw 3, pipe fitting departs from base 1 through U-shaped opening 2 from base 1 side, on a support plate 5 in described two support plates 5, by rotating shaft 10, be rotatably connected to baffle plate 9, baffle plate 9 is provided with away from one end of rotating shaft 10 groove that Open Side Down, and another piece support plate 5 in two support plates 5 is provided with minor axis 11, and minor axis 11 engages with the described groove of baffle plate 9.
