A spring 16 is welded, and a guide rod 17 is fixed to the spring 16. A fixing component is provided between the pull plate 12 and the slider 11. A mounting plate 18 is fixed to one side of the slider 11 by bolts. The slider 11 is pushed to move along the slide 10, thereby moving the mounting plate 18, so that the device can adapt to PTC controller assemblies of different widths. A threaded rod is fixed to the top of the mounting plate 18 by bolts. A pressure block is connected to the outer thread of the threaded rod. The connecting ends of the four corners of the PTC controller assembly are inserted into the threaded rod, and the pressure block is rotated to make it contact with the connecting end of the PTC controller assembly, thereby fixing the position of the PTC controller assembly.

[0025] In the present utility model, it should be noted that two first electric push rods 2 are fixed to the bottom inner wall of the base 1 by bolts, and the extended ends of the two first electric push rods 2 are installed with a bottom plate 3, and a plurality of slide rods 7 are inserted into the interior of the bottom plate 3. The top ends of the plurality of slide rods 7 are fixed with a top plate 8 by bolts. The first electric push rod 2 is extended to make the bottom plate 3 drive the top plate 8 to move upward and contact with the bottom of the PTC controller assembly, so that the device supports the bottom of the PTC controller assembly of different thicknesses, and the bottom end of the slide rod 7 passes through the bottom plate 3 and is sleeved with a first tension spring 9, and the two ends of the first tension spring 9 are respectively fixed to the bottom plate 3 and the slide rod 7, and the first tension spring 9 can contact the top plate 8. The plate 8 is used for buffering to prevent the first electric push rod 2 from directly driving the top plate 8 to support the PTC controller assembly. A plurality of second telescopic rods are fixed to the bottom of the bottom plate 3 by bolts, and the second telescopic rods are fixed to the base 1. The fixing component includes two clamping blocks 14, and the two clamping blocks 14 are fixed to the bottom of the pull plate 12 by bolts. A plurality of clamping grooves 13 are opened on the top of the connecting plate 5, and the plurality of clamping grooves 13 are symmetrically distributed on both sides of the sliding mouth 10, and the clamping blocks 14 are clamped with the clamping grooves 13.

[0026] Working principle: When the PTC controller assembly needs to be clamped, first pull the pull plate 12 upward to separate the block 14 from the slot 13. At the same time, the guide rod 17 pulls the spring 16 to extend. At this time, the position of the slider 11 is no longer restricted, and the slider 11 is pushed to move along the slide 10, thereby moving the mounting plate 18. The staff determines the moving distance of the mounting plate 18 according to the width of the PTC controller assembly. After the adjustment is completed, release the pull plate 12, and the spring 16 rebounds to make the block 14 enter the slot 13 at the corresponding position, and then start the second electric push rod 4. The second electric push rod 4 extends, and the staff drives the connecting plate 5 to move the mounting plate 18 inward to a suitable position according to the length of the PTC controller assembly, and then The connecting ends at the four corners of the PTC controller assembly are inserted into the threaded rod, and the pressure block is rotated to make it contact with the connecting ends of the PTC controller assembly, so that the device can clamp and fix PTC controller assemblies of different sizes. When the PTC controller assembly needs to be supported, the first electric push rod 2 is started, and the first electric push rod 2 is extended to make the bottom plate 3 drive the top plate 8 to move upward and contact the bottom of the PTC controller assembly. The first electric push rod 2 continues to extend. At this time, the top plate 8 is pushed by the PTC controller assembly, so that the first tension spring 9 is extended until the top plate 8 contacts the bottom plate 3, thereby supporting the bottom of the PTC controller assemblies of different thicknesses, and then the device is convenient for the staff to install PTC controller assemblies of different sizes.
