At this time, the latching teeth 32 are away from the ratchet portion 156, so that the pivot shaft 31 can slide relative to the sliding slot 14. The second clamp 23 can adjust the second clamp with respect to the first clamp 13 The adjustment position of the relative position of the unit 2 and the first jaw unit 1.

It should be noted that, since the second grip 22 is pulled apart to adjust the gripping diameter as shown in FIG. 8, it is also possible to maintain the existing gripping diameter as shown in FIG. The second clamp 23 and the first clamp 13 hold the other workpiece. Therefore, in order to prevent the excessive force from moving the latch 32 away from the ratchet 155 to the adjusted position, the elastic member 35 of the pivot unit 3, and the protector 36, and the second side portion The 152 cooperates to form a protection mechanism that ensures the existing clamping pipe diameter and holds the workpiece. The implementation of the protection mechanism will be specifically described below.

Referring again to FIG. 7, when the user only needs to clamp the workpiece of the fixed diameter, the second grip 22 is pulled apart, and the second body 21 drives the pivot 31 to rotate while driving the protection member 36 along the second The side portion 152 slides, the protection member 36 abuts against the second side portion 152 at a top dead center D, and the elastic member 35 stores an elastic restoring force that prevents the second clamp 23 from continuing to move to the adjusted position. In this way, as long as the user does not apply a tensile force exceeding the elastic restoring force, the existing clamping pipe diameter can be maintained and the workpiece can be clamped.

Referring to FIG. 6 and FIG. 8 , when the user applies a pulling force to the second grip 22 that exceeds the elastic restoring force, the protecting member 36 slides away from the top dead center D, and the latching teeth 32 are away from the spine. The tooth portion 156 moves the second clamp 23 to the adjustment position as shown in Fig. 8. At this time, the work of adjusting the gripping diameter can be performed. After the adjustment is completed, the second grip 22 is only required to apply a thrust exceeding the elastic restoring force, so that the protector 36 can slide away from the top dead center D in the opposite direction, and the latch 32 is re-engaged. After the ratchet portion 156 is fixed, the second clamp 23 is returned to the clamp position as shown in FIG. 6 after the clamp pipe diameter is fixed.

In summary, the adjustable water pipe clamp of the present invention is disposed on the driving hole 212 by the pivot 31, and when the second grip 22 is pulled apart, the latch 32 can be driven away from the ratchet portion 156, and The clamping pipe diameter is adjusted, and the clamping teeth can be engaged with the ratchet portion 156 to fix the clamping pipe diameter, and the protection member 36 and the elastic member 35 and the second side portion 152 are protected. The mechanism is more convenient and intuitive to use, so it can achieve the purpose of this new type.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
