[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-3 This utility model provides a technical solution: a plasma spraying protective fixture, including a plasma spraying gun 1, one end of a thick rod 2 is fixedly installed at the bottom of the plasma spraying gun 1, a first rotating shaft is rotatably installed at the other end of the thick rod 2, a protective plate 3 is rotatably installed on the first rotating shaft, a sliding hole 4 is opened on one side of the thick rod 2, a sliding rod 5 is slidably installed in the sliding hole 4, both ends of the sliding rod 5 extend outside the sliding hole 4, and a stop bar 6 is fixedly installed at both ends of the sliding rod 5 extending outside the sliding hole 4.

[0030] Combination Figure 1-2 As shown, a storage groove 7 is provided on one side of the thick rod 2. A telescopic rod 8 is slidably installed in the storage groove 7. One end of the telescopic rod 8 extends into the storage groove 7, and the other end of the telescopic rod 8 extends out of the storage groove 7. A through hole 9 is provided at the top of the telescopic rod 8. A locking rod 10 is fixedly installed on the inner wall of one side of the through hole 9. A locking groove 11 is provided on one side of the stop rod 6. A first magnet 12 is fixedly installed at the end of the telescopic rod 8 that extends into the storage groove 7. A second magnet 13 is fixedly installed on the inner wall of one side of the storage groove 7.

[0031] Combination Figure 1-3 As shown, a sliding groove 14 is provided at the bottom of the plasma spray gun 1, and a sliding block 15 is slidably installed in the sliding groove 14. One end of the sliding block 15 extends into the sliding groove 14, and the other end of the sliding block 15 extends out of the sliding groove 14. A fixing groove 16 is provided on one side of the sliding block 15.

[0032] Combination Figure 1-3As shown, the sliding rod 5 is located at the top of the sliding hole 4, the bottom of the stop rod 6 is in contact with the top of the protective plate 3, the slot 11 is located on the side of the stop rod 6 near the stop rod 10, and the stop rod 10 is adapted to the slot 11.
