Specifically, one end of the fixed seat 2 is provided with a rubber pad 24. The rubber pad 24's setting can effectively reduce the harm of fixing base 2 when pressing from both sides tight pipe fitting to the wall.

The working principle is as follows: the staff firstly directs the opening of the device to the pipe connection part to be adjusted, then holds the clamp rod 1 to push forward until the fixing seat 2 butts against the wall, then through the fixing component 4, the fixing seat 2 clamps the pipe at the lower part tightly, then through rotating the rotating rod 51 in the rotating component 5 above the clamp rod 1, the cam 52 on the rotating rod 51 rotates, so that the pressing plate 12 clamps the pipe at the upper part tightly under the action force of the pressure spring 13, it is worth noting that the rotating rod 51 rotates along with the small-amplitude rising and falling, because the channel for containing the fixture block 55 is arranged in the second sleeve 54, the fixture block 55 is movably connected with the second sleeve 54, so that in the rotating process of the rotating rod 51, not only the second sleeve 54 can be driven to rotate through the fixture block 55, but also the rising and falling spaces are reserved for the rotating rod 51, thereby starting the pipe rotation operation after clamping the pipe at the upper part tightly, taking the upper pipe fitting to be unscrewed rightwards as an example, the clamping bar 1 is held to rotate rightwards, in the rotating process, the clamping bar 1 is rotatably connected with the fixed seat 2 through the rotating column 3, because the second sliding groove 22 is further arranged on the fixed seat 2, the clamping bar 1 can stably rotate rightwards through the sliding fit of the sleeve at the lower part of the rotating rod 51 and the second sliding groove 22, when the rotating rod 51 rotates to the right end of the second sliding groove 22, the second pawl 232 on the second adjusting assembly 23 beside the second sliding groove 22 is contacted and meshed with the first gear 56 on the second sleeve 54, the second pawl 232 is tightly supported by the second fixed block 231 and cannot rotate backwards, the first gear 56 on the second sleeve 54 rotates, the rotating rod 51 is driven to rotate through the fixture block 55, so that the two compression plates 12 loosen a little distance from the upper pipe fitting, and then the clamping bar 1 rotates back, in the returning process, due to the arrangement of the third spring 233, the first gear 56 on the second sleeve 54 does not rotate when contacting with the second pawl 232, and when the clamp lever 1 moves to the middle of the fixed seat 2, the first gear 56 on the second sleeve 54 contacts with the second adjusting component 23 and resets and rotates, so that the rotating rod 51 rotates reversely, and clamps the upper pipe again, without manually adjusting the clamping distance, thereby improving the practicability of the device, it is worth noting that, in the rotating process of the clamp lever 1, the small-amplitude rising and falling of the upper pipe can be accompanied, because the upper part of the fixed seat 2 is provided with the first chute 21, the rotary column 3 is movably connected with the fixed seat 2 through the first chute 21, so that in the rotating process of the rotary column 3, the fixed seat 2 reserves a space for rising and falling of the rotary column 3 through the first chute 21, so that the device can better cooperate with the pipe to rotate as a whole, the practicability of the device is improved, after the pipe fitting rotates for a certain distance, a part of the pipe fitting at the upper part is exposed out of threads, the diameter of the part of the pipe fitting is smaller than the distance between the two pressing plates 12 at the initial stage, at the moment, after the pipe fitting is rotated and reset through the clamp rod 1, the pressing plates 12 cannot completely clamp the pipe fitting, the first sliding block 14 in the pressing plates 12 slides out under the action of the first spring 15, the first sliding block 14 drives the second gear 63 to rotate through the first tooth 67, the second gear 63 drives the first bevel gear 65 to rotate through the first rotating shaft 61, the first bevel gear 65 is meshed with the second bevel gear 66, the third gear 64 on the second rotating shaft 62 is rotated, the second sliding block 16 descends through the meshing of the third gear 64 and the second tooth 68, at the moment, the first adjusting component 17 in the second sliding block 16 adopts the same working principle as the second adjusting component 23, make first pawl 172 and the meshing of first gear 56 on the first sleeve 53 when the contact, the rotation through first gear 56 drives dwang 51 and continues to rotate a section distance, make two pressure strips 12 can press from both sides the pipe fitting once more tightly, through the setting of drive assembly 6 in the pressure strip 12, make the screw pipeline that the diameter is littleer to compensate the centre gripping after the pipe fitting is rotatory, make tong bar 1 when meetting the pipeline diameter and changing, still can the self-adaptation centre gripping pipe fitting, do not need manual regulation, the human labor cost has been reduced, and the work efficiency is improved, and press from both sides the pipe fitting tightly the back, first sliding block 14 resets, through the same theory of operation, first adjusting part 17 rises along with second sliding block 16, first pawl 172 can not contact with first gear 56 and mesh, the holistic practicality of device has been guaranteed.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
