The utility model discloses an automobile door panel anti-bubble veneer gluing jig which comprises two first clamping plates which are longitudinally arranged in parallel, a telescopic connecting rod is transversely arranged at the top between the two first clamping plates, two first guide rods are arranged on the side, corresponding to the other first clamping plate, of one first clamping plate, and two second guide rods are arranged on the side, corresponding to the other first clamping plate, of the other first clamping plate. The first guide rod vertically penetrates through the other first clamping plate and is in sliding connection with the first clamping plate, second clamping plates matched with the first clamping plates are arranged on the lower sides of the two first clamping plates respectively, and clamping assemblies are arranged on the opposite sides of the two first clamping plates and correspond to the corresponding second clamping plates respectively; the first clamping plate and the second clamping plate are matched with the clamping assembly for clamping and fixing, the clamped patch is pulled to be tightened through the telescopic connecting rod, and the first clamping plate and the second clamping plate are used for clamping to enable the patch to be in a flat state when the patch is pulled to be in a tightened state, so that bubbles are prevented from being generated during attaching, the leather attaching efficiency is improved, and the service life of the patch is prolonged. And the veneer gluing effect is improved.

This invention belongs to the field of microbial application technology, specifically relating to a method for preparing fermented *Lactobacillus limnoxicamis* extracellular vesicles, the product, and its applications, particularly the application of these fermented *Lactobacillus limnoxicamis* extracellular vesicles and their lyophilized formulations in the preparation of products with antioxidant or anti-aging effects. In this invention, *Lactobacillus limnoxicamis* is inoculated into a modified extracellular vesicle induction medium for fermentation. After culture, a two-stage solid-liquid separation is performed, and the supernatant is collected to obtain the extracellular vesicle processing solution. This solution is purified using a capillary electrophoresis system, and the positive extreme liquid is collected and filtered to obtain the purified product of fermented *Lactobacillus limnoxicamis* extracellular vesicles. The extracellular vesicles derived from fermented *Lactobacillus limnoxicamis* prepared by this invention can effectively scavenge free radicals. Somatic cell experiments have demonstrated its excellent anti-aging properties, and the transformation and application research of *Lactobacillus* extracellular vesicles has explored its development potential in the field of anti-aging products.

This invention provides a non-contact, adjustable alternating magnetic field-eddy current coupled laser shock strengthening device and method for improving hydrogen embrittlement resistance. The device includes a laser shock strengthening unit, a magnetic field generating unit, a driving unit, and a position adjustment unit. The magnetic field generating unit has alternating N and S pole permanent magnets, which are driven to rotate by the driving unit. This induces an alternating magnetic field and closed eddy currents within the metal workpiece. The magnetic field strength, eddy current density, and temperature rise are synergistically controlled by adjusting the air gap and rotation speed. This invention couples a multi-directional alternating electromagnetic field during laser shock, promoting the activation of multiple slip systems and dislocation dispinning, improving the surface microstructure uniformity and residual compressive stress distribution, effectively inhibiting hydrogen intrusion and enrichment, delaying the initiation and propagation of hydrogen-induced cracks, and improving the workpiece's resistance to hydrogen embrittlement. The device has no contact electrodes and is suitable for complex curved surfaces and large-area workpieces.

This invention belongs to the field of functional microbial technology, specifically relating to a fermented *Lactobacillus rimoxifer* and its application in anti-aging. The fermented *Lactobacillus rimoxifer* F-B9-1-2 and its culture provided by this invention exhibit significant in vitro antioxidant capacity. A 0.5 mg / mL culture showed a scavenging rate of 89.3±2.1% for ABTS free radicals, demonstrating its antioxidant efficacy by reducing free radical damage to cells and maintaining normal cell function. Furthermore, treatment with its culture reduced the SA-β-gal positive cell rate from 12.8% to 7.1%, exhibiting good in vivo antioxidant activity, thus helping to inhibit or alleviate the aging process.
