[0002] During the production process of the central control screen bracket for new energy vehicles, the product needs to be partially sprayed. In order to prevent other parts of the central control screen bracket from being painted, an aluminum alloy masking fixture is usually used to wrap the part of the product that needs to be masked, thereby achieving the purpose of masking.

[0003] Chinese patent CN222197427U discloses a spraying masking fixture, which includes a spraying area and a non-spraying area. The spraying area is located on one side of the non-spraying area. The spraying masking fixture includes a first fixture and a second fixture. The first fixture engages with the second fixture to fix the product between the first fixture and the second fixture. The first fixture includes a support member, a masking component, and a cover plate. One end of the support member is fixedly connected to the cover plate, and the other end abuts against the second fixture. The masking component is located on one side of the support member. One side of the masking component is adhered to the cover plate, and the other side covers the non-spraying area. However, this device still has the following problems. During the painting process of the central control screen bracket, it is necessary to accurately position the central control screen bracket and avoid the protruding parts of the central control screen bracket. However, the aforementioned patent cannot effectively fix and accurately position the central control screen bracket, thereby ensuring the accuracy of the masking boundary and preventing paint leakage.
