DETAILED DESCRIPTION
[0033] 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.

[0035] The specific arrangement and function of the stretching device 4 and the wiping device 5 will be described in detail below.
[0036] like Figure 1-Figure 5 As shown, the stretching device 4 includes two support bars 403 fixedly connected to the inner side of the testing machine body 1, two first round tubes 401 and two second round tubes 402 are placed above the two support bars 403, and a slide groove 405 is provided on the side of the first round tube 401 and the second round tube 402 close to each other, and a plurality of elastic ropes 408 are slidably connected to the inner side of the two slide grooves 405, and a sphere 410 is fixedly connected to both ends of the elastic rope 408, and a plurality of reserved grooves 404 are evenly provided on the upper surface of the support bar 403. When the testing machine body 1 needs to be used, the elastic rope 408 between the two slide grooves 405 of the first round tube 401 and the second round tube 402 is slid according to the size or shape of the parts to be placed, and the placement of parts of different sizes can be achieved by adjusting the density of the elastic rope 408, thereby preventing small parts from being easily dropped when placed on the elastic rope 408. The side wall of the second round tube 402 is fixedly connected to a limit plate 406, and the limit plate 406 is slidably connected to the inside of the first round tube 401. The limiting plate 406 slides inside the first circular tube 401 , thereby limiting the relative movement direction between the first circular tube 401 and the second circular tube 402 .
[0037] The first round tube 401 is internally threadedly connected with a screw rod 407, and the screw rod 407 is rotatably connected to the inside of the second round tube 402. When the screw rod 407 is rotated, the screw rod 407 rotates inside the first round tube 401, and the second round tube 402 can be driven. The side wall of the elastic rope 408 is evenly slidably covered with three rubber blocks 409. By setting the rubber blocks 409 to slide on the elastic rope 408, some strip-shaped structural products between the rubber blocks 409 can be placed in contact with each other.
[0038] like Figure 1 and Figure 6-Figure 9 As shown, the wiping device 5 includes a guide rod 53 fixedly connected to the inner side of the shield 2, and a moving frame 51 is slidably connected to the side wall of the guide rod 53, and a rubber strip 52 is glued to the upper surface of the moving frame 51. The moving frame 51 drives the rubber strip 52 and the shield 2 to move relative to each other, and at this time, the water droplets adhering to the inner side of the shield 2 can be scraped off.
[0039] The inner part of the shield 2 is rotatably connected with a screw rod 54, and the screw rod 54 is connected to the inner thread of the mobile frame 51. The side wall of the testing machine body 1 is fixedly installed with a mounting rod 57, and the upper end of the mounting rod 57 is fixedly connected with a motor 56, and the output end of the motor 56 is fixedly connected to the screw rod 54. When the motor 56 is started, the motor 56 will drive the screw rod 54 to rotate, and the driving work of the mobile frame 51 can be realized. Both sides of the rubber strip 52 are provided with guide grooves 55. By providing the guide grooves 55, it is convenient to guide the water flow formed by the water droplets after scraping.
[0040] Working principle: 1. When the testing machine body 1 needs to be used, slide the elastic rope 408 between the two slide grooves 405 of the first round tube 401 and the second round tube 402 according to the size or shape of the parts to be placed. By adjusting the density of the elastic rope 408, the placement of parts of different sizes can be achieved, avoiding the situation where small parts placed on the elastic rope 408 are prone to fall. Turn the screw 407, and the screw 407 will rotate inside the first round tube 401. At this time, the driving work of the second round tube 402 can be achieved, thereby increasing the distance between the two ends of the elastic rope 408, which is convenient for the placement of more small parts. The limiting plate 406 slides inside the first round tube 401 to limit the first round tube 401 and the second round tube The tubes 402 have the effect of relative movement in the moving direction. The first round tube 401 and the second round tube 402 are placed on the inner side of the reserved groove 404 on the support bar 403, which can improve the stability of placing the first round tube 401 and the second round tube 402. By setting the rubber block 409 to slide on the elastic rope 408, some strip structure products between the rubber blocks 409 can be in contact with each other during the placement process, which further improves the measurement effect of the corrosion resistance of some strip structure parts. By setting the stretching device 4, the elastic rope 408 is stretched and discharged, which facilitates the support work of some small metal parts, and further improves the measurement effect of the corrosion resistance of some small metal parts using the salt spray tester.
[0041] When it is necessary to observe the corrosion of metal parts on the testing machine body 1, start the motor 56, and the motor 56 will drive the screw 54 to rotate. At this time, the driving work of the movable frame 51 can be realized, and the movable frame 51 will drive the rubber strip 52 and the baffle 2 to move relative to each other. At this time, the scraping work of the water droplets adhering to the inner side of the baffle 2 can be realized. By setting the guide groove 55, it is convenient to guide the water droplets to form a water flow after scraping, and avoids the situation where the water droplets directly fall on the parts and cause serious corrosion to the metal parts. By setting the wiping device 5, it is convenient to wipe the condensed water droplets on the inner side of the baffle 2, thereby facilitating the observation of the inner side of the baffle 2.
