The positioning sleeve rod 4 is a hollow pipe fitting, and the positioning sleeve rod 4 is adapted to the positioning rod 6; an adjusting mechanism is also included, and the adjusting mechanism is installed on the top of the fixing part 3 through an adjusting cylinder 5 in the adjusting mechanism, and is used to stack and limit multiple carrier bodies 2, and a chamfer 14 is provided at the top of the adjusting cylinder 5.

[0022] In this embodiment, if Figure 2 and Figure 3 As shown, the adjustment mechanism also includes a fixing column 9 fixed inside the adjustment tube 5 , a limiting plate 10 is fixed at the top of the fixing column 9 , the inner diameter of the positioning sleeve 4 is adapted to the limiting plate 10 , and the positioning sleeve 4 can slide on the limiting plate 10 .

[0023] In this embodiment, if Figure 2 and Figure 3 As shown, the adjusting cylinder 5 is provided with a movable long hole 7 of the same length as the adjusting cylinder 5, and a plurality of equally spaced placement holes 8 are provided on the adjusting cylinder 5, and the plurality of placement holes 8 are all connected with the movable long hole 7, a sliding plate 11 is sleeved on the fixing column 9, and the sliding plate 11 is slidably connected with the fixing column 9, a support rod 12 is fixed on the sliding plate 11, and the support rod 12 is located in the placement hole 8, and also includes a thrust spring 13, which is sleeved on the outer side of the fixing column 9, and the thrust spring 13 is respectively connected with the fixing part 3 and the sliding plate 11, and the thrust spring 13 is located below the sliding plate 11, and the sliding plate 11 can rotate and slide freely on the fixing column 9, and the support rod 12 can move vertically in the movable long hole 7.

[0024] When placing, first straighten the support base 1, and then respectively sleeve the positioning sleeve rod 4 on the first carrier body 2 on the positioning rod 6 to limit the position, and place the workpieces one by one on the carrier body 2. When installing the second carrier body 2, the support rod 12 in the placement hole 8 can be moved to make the sliding plate 11 rotate on the fixed column 9. When the support rod 12 is located in the movable long hole 7, pushing up or pulling down can change the height of the sliding plate 11, thereby realizing the function of spacing adjustment. After the adjustment is completed, it is only necessary to rotate the support rod 12 again to move it into the placement hole 8. Because the sliding plate 11 is pushed by the thrust spring 13, the friction between the support rod 12 and the groove wall of the placement hole 8 is increased, thereby improving stability. Subsequently, the positioning sleeve rod 4 on the second carrier body 2 can be sleeved on the fixed column 9. The operation is simple, convenient and fast.

[0025] The implementation principle of a heat treatment carrier in the embodiment of the present application is as follows: when placing, first straighten the support base 1, and then respectively sleeve the positioning sleeve rods 4 on the first carrier body 2 on the positioning rods 6 to limit the position, and place the workpieces one by one on the carrier body 2.

When the support rod 12 is located in the moving long hole 7, pushing up or pulling down can change the height of the sliding plate 11, thereby realizing the function of spacing adjustment. After the adjustment is completed, it is only necessary to rotate the support rod 12 again to move it into the placement notch 8. Because the sliding plate 11 is pushed by the thrust spring 13, the friction between the support rod 12 and the groove wall of the placement notch 8 is increased, thereby improving stability. Subsequently, the positioning sleeve rod 4 on the second carrier body 2 can be sleeved on the fixed column 9. The operation is simple, convenient and fast.

[0026] By arranging the positioning sleeve 4, the adjusting tube 5, the movable long hole 7, the placement hole 8, the fixing column 9, the sliding plate 11 and the supporting rod 12, the sliding plate 11 is rotated so that the supporting rod 12 is in the movable long hole 7, so that the positioning sleeve 4 can be vertically moved in the adjusting tube 5, thereby increasing the distance between the two carrier bodies 1, thereby realizing the function of adjusting the carrier spacing, facilitating the placement of workpieces of different thicknesses or heights for heat treatment, and improving practicality. In addition, the thrust spring 13 seat is arranged to assist in pushing up the sliding plate, which further saves manpower and improves practicality.
