Two inner groove rings are threadedly connected to the motor 12, and the outer ring tops of the two inner groove rings are respectively fixedly connected to the corresponding moving seats. The motor 12 in the fixing mechanism 1 drives the bidirectional screw rod 13 to rotate, thereby causing the two limit assemblies 14 slidably connected in the slide groove to move, thereby achieving clamping and limiting of pipes of different widths.

[0024] The bottom of the fixing mechanism 1 is symmetrically provided with lifting components 2 for support. An adjusting member 3 for driving adjustment is provided between the symmetrical lifting components 2.

A spring group 143 for buffering is connected between the arc plate 2 142 and the arc plate 1 141. The setting range of the spring group 143 is two to five. In this embodiment, three are used, and they are distributed in an arc shape along the arc surface at the top of the arc plate 141. The symmetrically arranged through holes are respectively located on the front and rear sides of the spring group 143.

[0026] The bottom of the connecting plate 145 is slidably connected to a pressing plate 146, and the bottom of the pressing plate 146 is symmetrically provided with a limiting column 147 for tightening and limiting.

[0027] The lifting assembly 2 includes a sleeve 21, and a threaded rod 22 is rotatably connected to the bottom inner wall of the sleeve 21 through a bearing. An inner threaded sleeve 23 and a driven bevel gear 24 are sleeved on the threaded rod 22. The inner threaded sleeve 23 is threadedly connected to the threaded rod 22, and the inner threaded sleeve 23 is located above the driven bevel gear 24. The top of the inner threaded sleeve 23 penetrates the top shell wall of the sleeve 21 and is fixedly connected to a pad. The pad is fixedly connected to the bottom outer wall of the support plate 11 by bolts. A guide groove is provided on the outer ring shell wall of the inner threaded sleeve 23 in the circumferential direction, and a protrusion is provided on the top inner wall of the sleeve 21 in the circumferential direction. The protrusion is slidably connected to the guide groove, thereby providing a guiding effect for the movement of the inner threaded sleeve 23.

[0028] A driving bevel gear 25 meshing with the driven bevel gear 24 is provided above the driven bevel gear 24. A transmission shaft 26 is installed on the side wall of the driving bevel gear 25, and the other end of the transmission shaft 26 penetrates the corresponding shell wall of the sleeve 21 and is provided with a cross groove. A fixing ring 27 is integrally provided on the peripheral wall of the portion of the transmission shaft 26 extending out of the sleeve 21, and a plurality of holes are provided on the fixing ring 27 along the circumferential direction. The side of the hole is correspondingly provided with a limiting hole located on the sleeve 21. The adjusting member 3 includes a sleeve 31, and both ends of the sleeve 31 are slidably connected with a straight rod 32. The straight rod 32 is locked with the sleeve 31 by a fastening bolt, and the end of the straight rod 32 away from the sleeve 31 penetrates the corresponding end wall of the sleeve 31, and is integrally provided with a cross protrusion plate corresponding to the cross groove. The cross protrusion plate fits with the cross groove, so that the adjusting member 3 can synchronously drive the transmission shafts 26 in each lifting assembly 2 to rotate synchronously when rotating itself.

[0029] Each straight rod 32 is movably connected with a stopper 33 for tightening and limiting. The stopper 33 includes a moving ring 331 slidably connected to the straight rod 32, and the side of the moving ring 331 close to the sleeve 31 is rotatably connected with an inner ring 332. The inner ring 332 is threadedly connected to the straight rod 32, and a plurality of stopper rods 333 for inserting and limiting are arranged along the circumferential direction on the side of the moving ring 331 away from the sleeve 31. A plurality of straight grooves are opened along the circumferential direction on the outer ring of each straight rod 32, and a slider is slidably connected in the straight groove. The top of the slider is fixedly connected to the inner ring shell wall of the moving ring 331, thereby guiding and supporting its displacement movement on the straight rod 32. The number of the stopper rods 333 is consistent with the holes on the fixed ring 27 and the stopper holes on the sleeve 21, and the setting range is three to nine. In this embodiment, six are used.

[0030] The working principle of the utility model is as follows: when the product is in use, the fixing mechanism 1 is adjusted according to the width of the pipe to be fixed. The motor 12 is started to drive the bidirectional screw rod 13 to rotate, and then the movable seat in the corresponding limit assembly 14 is driven to adjust the displacement through the inner ring. When the limit assembly 14 is adjusted to a suitable position, the pipe to be fixed is placed on the arc plate 142 on the limit assembly 14, and then the motor 12 is started again to drive the bidirectional screw rod 13 to rotate, so that the symmetrical limit assemblies 14 are close to each other, thereby clamping the pipe. In the process of the limit assembly 14 clamping the pipe, the arc plate 142 uses the compression buffer of the titanium spring group 143 to avoid deformation of the pipe due to clamping. In the process of the arc plate 142 squeezing the pipe, the guide rod 144 connected to it moves, driving the connecting plate 145 to move downward, thereby causing the pressure plate 146 slidably connected to the connecting plate 145 to move downward, realizing the movement of its upper limit column 147. When the limiting column 147 is adjusted downward along with the pressing plate 146 , it comes into close contact with the top shell wall of the support plate 11 , thereby further achieving the limiting fixation of the limiting assembly 14 on the support plate 11 .

[0031] When height adjustment is required, the straight rod 32 in the adjusting member 3 that is movably connected to the two ends of the sleeve 31 is pulled out to a suitable length, and the cross protrusion at the end of the straight rod 32 is embedded in the cross groove on the transmission shaft 26 in the corresponding lifting assembly 2. Then, the limit locking between the straight rod 32 and the sleeve 31 is achieved by fastening bolts. Finally, by rotating and adjusting the adjusting member 3 as a whole, the transmission shaft 26 in the corresponding lifting assembly 2 connected at both ends thereof moves synchronously. The rotation of the transmission shaft 26 drives the active bevel gear 25 and the fixing ring 27 to rotate synchronously. When started, the active bevel gear 25 and the corresponding driven bevel gear 24 are meshed and transmitted, thereby driving the corresponding threaded rod 23 to rotate. The rotation of the threaded rod 22 causes the inner threaded sleeve 23 threaded thereon to be raised and lowered, thereby synchronously achieving the raising and lowering adjustment of the fixing mechanism 1.

[0032] After the adjustment of the lifting component 2 is completed, the limiting member 33 on the straight rod 32 in the adjusting member 3 is adjusted, and the inner ring 332 is rotated to make the movable ring 331 slide on the straight rod 32, so that the limiting rod 333 thereon passes through the hole on the fixed ring 27 and is inserted into the limiting hole on the shell wall of the sleeve 21, thereby realizing the limiting effect of the lifting component 2.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
