The recess formed integrally on the top of the suction cup 1 and the heating coil 3 installed in the recess on the inner side of the install ring 2 can be started after the power is turned on, which is used for heating the suction cup 1 to avoid the texture of the suction cup 1 becoming hard under low temperature conditions and reduce the influence on the success rate of taking the baffle.

[0024] The plurality of magnetic attraction parts 4 distributed in the recess on the top of the install ring 2 and the plurality of through holes 5 distributed on the flange at the bottom of the suction cup fixed base 100. Since the magnetic attraction parts 4 can be separated, after the magnetic attraction parts 4 are separated, one part of the structure is inserted through the corresponding through hole 5 and fixed to the other part of the structure on the magnetic attraction part 4 to realize the convenient installation of the suction cup 1 on the bottom of the suction cup fixed base 100.

[0025] It should be noted that the suction cup 1 is made of silica gel material, which has better elasticity under low temperature than traditional rubber material, and can improve the success rate of taking the baffle.

[0026] In an embodiment, the inner side of the mounting ring 2 is provided with a first conductive copper sheet 6 electrically connected with the heating coil 3, and the inner cavity of the suction cup fixing seat 100 is provided with a second conductive copper sheet 7 electrically connected with the first conductive copper sheet 6, and the second conductive copper sheet 7 is electrically connected with a PID controller. In this way, by forming a silica gel block on one side of the inner side of the mounting ring 2, embedding the first conductive copper sheet 6 in the groove on the outer surface of the silica gel block, then screwing the second conductive copper sheet 7 at the position opposite to the first conductive copper sheet 6 in the suction cup fixing seat 100, and electrically connecting the contact lead wire on the second conductive copper sheet 7 with the PID controller, the contact electrical connection of the first conductive copper sheet 6 and the second conductive copper sheet 7 is realized simultaneously after the suction cup 1 is combined at the bottom of the suction cup fixing seat 100.

[0027] In an embodiment, the inner side of the mounting ring 2 is provided with a temperature sensor, and the temperature sensor is electrically connected with the PID controller through the contact of the first conductive copper sheet 6 and the second conductive copper sheet 7.
