[0021] 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.

[0022] See also Figure 1-4 In this embodiment, a vacuum drying oven with an adjusting device comprises a vacuum drying oven body 1, and an adjusting mechanism is installed inside the vacuum drying oven body 1.

[0023] The adjusting mechanism comprises a mounting plate 2 and a shelf 3. There are two mounting plates 2. The two mounting plates 2 are mounted on the left and right inner side walls of the vacuum drying box body 1. A plurality of adjusting plates 6 are slidably connected to the mounting plate 2. A second slider 9 is fixedly connected to the side of the adjusting plate 6 close to the mounting plate 2. The second slider 9 is slidably connected in a second slide groove 8 provided on the front surface of the mounting plate 2. A mounting cavity 14 is provided inside the second slider 9. A ring plate 16 is slidably connected inside the mounting cavity 14. A limiting rod 12 is fixedly connected inside the ring plate 16. A spring 15 installed inside the mounting cavity 14 is sleeved on the outside of the limiting rod 12. A plurality of limiting grooves 13 located inside the second slide groove 8 are provided inside the mounting plate 2. The limiting rod 12 passes through the second slider 9 and is inserted into the limiting groove 13. A limiting member for limiting the shelf 3 is mounted on the adjusting plate 6.

[0024] It should be noted that by pulling the pull block 7 to drive the limit rod 12 out of the limit groove 13, the adjustment plate 6 can be moved up and down to adjust the position. Then, let go and the limit rod 12 can be inserted into the corresponding limit groove 13 through the rebound force of the spring 15 to limit the adjustment plate 6, thereby facilitating the adjustment of the distance between the shelves 3.

[0025] See also Figure 2 , Figure 3 The end of the limiting rod 12 away from the limiting groove 13 passes through the adjustment plate 6 and extends to the outside and is fixed with a pull block 7. The adjustment plate 6 is an "L"-shaped plate. The side of the adjustment plate 6 close to the mounting plate 2 is fixedly connected with a first slider 11. The side wall of the mounting plate 2 is provided with a first slide groove 4, and the first slider 11 is slidably connected to the inside of the first slide groove 4.
