In this way, by providing the above-mentioned base 40, the fixing mechanism 100 is modularly configured, which facilitates the overall installation, transportation, and disassembly of the fixing mechanism 100, thereby improving convenience.

When the external driving mechanism drives the first clamping member 22 to approach the bearing seat 10, the first clamping member 22 drives the first rack 26 to move, the first rack 26 drives the gear to rotate in the opposite direction, and the gear drives the second rack 28 to move in the opposite direction of the first rack 26, so that the second rack 28 drives the second clamping member 24 to move in the opposite direction of the first clamping member 22, that is, to move closer to the bearing seat 10.

[0067] In the embodiment of the present application, both the first magnetic member 32 and the second magnetic member 34 can be magnets, the first magnetic member 32 is embedded in the first clamping member 22, and the second magnetic member 34 is embedded in the bearing seat 10. In this way, the first magnetic member 32 and the second magnetic member 34 are low in cost and easy to obtain, which is conducive to reducing the manufacturing cost of the fixing mechanism 100.

[0068] It can be understood that in other embodiments, the first magnetic member 32 and the second magnetic member 34 can also be electromagnets, and the first magnetic member 32 and the second magnetic member 34 are both used to generate magnetism when powered.

The structure of the fixing mechanism 100 is compact and can be used to fix the product 2 in a narrow space. The fixing mechanism 100 has a wide range of uses.

[0070] It can be understood that in other embodiments, the number of the clamping assemblies 20 can also be two groups, that is, the number of the first clamping members 22, the second clamping members 24 and other related structures are two or two groups, the two first clamping members 22 and the two second clamping members 24 are symmetrically arranged about the bearing seat 10, and the two first clamping members 22 and the two second clamping members 24 abut the product 2 from four directions. Alternatively, the number of the clamping assemblies 20 can also be three groups, that is, the number of the first clamping members 22, the second clamping members 24 and other related structures are three or three groups, the three first clamping members 22 and the three second clamping members 24 are symmetrically arranged about the bearing seat 10, and the three first clamping members 22 and the three second clamping members 24 abut the product 2 from six directions.

In this way, when the external driving mechanism drives the first clamping member 22 to move away from the bearing seat 10 through the traction member 50, the first clamping member 22 cooperates with the second clamping member 24 to make the second clamping member 24 overcome the magnetic attraction between the first magnetic member 32 and the second magnetic member 34 and move away from the bearing seat 10. When the external driving mechanism drives the first clamping member 22 to move closer to the supporting seat 10 through the traction member 50, the second clamping member 24 moves closer to the supporting seat 10 through the linkage cooperation with the second clamping member 24 and is connected to the supporting seat 10 through the magnetic attraction between the first magnetic member 32 and the second magnetic member 34, thereby achieving the clamping and release of the product 2 at the supporting seat 10.
