[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the embodiment, Figure 1-4 A clamping mechanism for loading a spare tire cover of an automobile is provided. The utility model comprises a shell 1, two threaded rods 2 are rotatably connected inside the shell 1, and an extension shaft 3 is fixedly connected to the opposite sides of the two threaded rods 2, two sliders 4 are fixedly connected inside the shell 1, and the opposite sides of the two sliders 4 are fixedly connected to a base 5, and the opposite sides of the two bases 5 are fixedly connected to a spring 6, the outer sides of the two threaded rods 2 are threadedly connected to a first clamping block 7, and the tops of the two sliders 4 are fixedly connected to a second clamping block 8;

[0028] One end of the two springs 6 is fixedly connected to the housing 1, and the opposite sides of the two bases 5 are fixedly connected to extension rods 9, and the opposite sides of the two extension rods 9 are fixedly connected to handles 10 located outside the housing 1;

[0029] The handle 10 allows the extension rod 9 to be easily moved by force;

[0030] The bottom of the bottom threaded rod 2 is fixedly connected with a short shaft 11, and the bottom of the short shaft 11 is fixedly connected with a roller 12;

[0031] The short shaft 11 can be rotated by the roller 12;

[0032] The outer side of the roller 12 is knurled, and the inside of the housing 1 is provided with moving grooves 13 adapted to two first clamping blocks 7 and two second clamping blocks 8;

[0033] The two first clamping blocks 7 and the two second clamping blocks 8 can be moved through the movable groove 13;

[0034] A telescopic rod 14 is fixedly connected to the bottom of the housing 1, and the two first clamping blocks 7 and the two second clamping blocks 8 are both arranged in an arc shape;

[0035] The housing 1 can be adjusted in height by means of the telescopic rod 14;

[0037] The trapezoidal arrangement enables the support block 15 to have better support performance.

[0038] Working principle:

[0039] Step 1: Rotate the roller 12 so that the roller 12 drives the bottom threaded rod 2 to rotate through the short shaft 11. The rotation of the bottom threaded rod 2 drives the extension shaft 3 to rotate. The rotation of the extension shaft 3 drives the top threaded rod 2 to rotate, thereby causing the two threaded rods 2 to drive the two first clamping blocks 7 to move.

[0040] Step 2: Then move the two handles 10 to the opposite side, so that the two handles 10 drive the two extension rods 9 to move, and then the two extension rods 9 drive the two bases 5 and the two sliders 4 to move to the opposite side, so that the two sliders 4 drive the two second clamping blocks 8 to move to the opposite side, and then place the material on the top of the shell 1, and release the two handles 10, so that the two springs 6 are elastically deformed to return the two bases 5 and the sliders 4, so that the material is initially limited by the second clamping block 8, and then the roller 12 is rotated, so that the roller 12 drives the two threaded rods 2 to rotate through the short shaft 11, so that the two first clamping blocks 7 limit the material for a second time, and the height of the shell 1 is adjusted by the telescopic rod 14, so that materials of different sizes can be clamped.
