When the PTC heating sheet body 1 moves into the installation slot 3, the locking block 13 corresponds to the position of the card slot 9, and the locking block 13 is locked with the card slot 9 under the action of the second spring 14. When the PTC heating sheet body 1 is disassembled, the paddle 15 is manually toggled, and the paddle 15 moves with the guide rod 12 and the locking block 13 to compress the second spring 14. At this time, the locking block 13 moves and disengages from the card slot 9, and the slide bar 5 is reset under the action of the first spring 6. The reset of the slide bar 5 brings the placement plate 7 and the PTC heating sheet body 1 out of the installation slot 3. During the maintenance process of the PTC heating sheet body 1, there is no need to disassemble and install the screws back and forth, and the maintenance process of the PTC heating sheet body 1 is convenient and quick, thereby improving the maintenance efficiency of the PTC heating sheet body 1.

[0033] Example 2

[0034] The existing PTC heating plate bodies 1 have different sizes. When installing the PTC heating plate bodies 1 of different sizes, in order to ensure the stability of the installation process of the PTC heating plate bodies 1, the following solution is used to solve the problem.

[0035] See also Figures 1 to 5, the basis for the combined implementation is different in that a clamping groove for fixing the PTC heating sheet body 1 is provided on the surface of the placement plate 7, and two clamping plates 16 are movably connected inside the clamping groove, and a third spring 17 is provided between any clamping plate 16 and the inner wall of the clamping groove, and the two clamping plates 16 are elastically connected to the clamping groove through the third spring 17, and a moving piece 18 is movably connected inside the clamping groove, and the moving piece 18 and the clamping plate 16 have a clamping effect on the surface of the PTC heating sheet body 1 under the action of the fourth spring 19 and the third spring 17, and the fourth spring 19 is elastically connected between the moving piece 18 and the inner wall of the clamping groove, and the moving piece 18 and the clamping groove are clamped by hand. The PTC heating sheet body 1 is taken up and placed into the clamping groove. During the placement of the PTC heating sheet body 1, since the top surfaces of the movable sheet 18 and the clamping plate 16 are both provided with rounded corners, the surface of the PTC heating sheet body 1 follows the rounded corners and squeezes the movable sheet 18 and the clamping plate 16 to move. When the PTC heating sheet body 1 is installed in the clamping groove, the movable sheet 18 and the clamping plate 16 have a clamping effect on the surface of the PTC heating sheet body 1 under the action of the fourth spring 19 and the third spring 17, which not only realizes the installation of PTC heating sheet bodies 1 of different sizes, but also makes the PTC heating sheet body 1 remain stable during the installation process.

[0036] The top surfaces of the movable sheet 18 and the clamping plate 16 are both provided with rounded corners, and the rounded corner design facilitates the installation of the PTC heating sheet body 1 into the clamping groove.

[0037] The utility model uses steps as follows: when the automobile PTC heating sheet installation auxiliary device is used, the PTC heating sheet body 1 is manually taken and placed in the clamping groove. During the placement of the PTC heating sheet body 1, since the top surfaces of the movable sheet 18 and the clamping plate 16 are both provided with rounded corners, the surface of the PTC heating sheet body 1 moves along the rounded corners and squeezes the movable sheet 18 and the clamping plate 16. The movement of the movable sheet 18 squeezes the fourth spring 19, and the movement of the clamping plate 16 squeezes the third spring 17. When the PTC heating sheet body 1 is installed in the clamping groove, the movable sheet 18 and the clamping plate 16 have a clamping effect on the surface of the PTC heating sheet body 1. The method involves manually taking the PTC heating sheet body 1 and placing it into the clamping groove. During the placement of the PTC heating sheet body 1, since the top surfaces of the movable sheet 18 and the clamping plate 16 are both provided with rounded corners, the surface of the PTC heating sheet body 1 follows the rounded corners and squeezes the movable sheet 18 and the clamping plate 16 to move. When the PTC heating sheet body 1 is installed into the clamping groove, the movable sheet 18 and the clamping plate 16 have a clamping effect on the surface of the PTC heating sheet body 1 under the action of the fourth spring 19 and the third spring 17, which not only realizes the installation of PTC heating sheet bodies 1 of different sizes, but also ensures that the PTC heating sheet body 1 remains stable during the installation process.
