A connecting frame 3 is fixedly installed in the middle of the outer surface of the rear end of the head support plate 2. A locking structure 9 is fixedly installed in the middle of the outer surface of the rear end of the waist support plate 1. The locking structure 9 includes a fixing block 10, a through hole 11, a guide hole 12, a pressing rod 13, a first mounting cavity 14, a limiting block 15, a compression spring 16, a second mounting cavity 17, a connecting rod 18, a pin 19, and a connecting hole 20. Support rods 6 are fixedly installed on the left and right sides of the lower outer surface of the connecting frame 3. Limiting holes 7 are equally spaced on the outer wall of the support rods 6.

[0026] There are two sets of support rods 6, and a U-shaped connector 8 is fixedly installed between the lower ends of the two sets of support rods 6. There are two sets of through holes 11, pins 19, and connecting holes 20. The two sets of through holes 11 are opened on the left and right sides of the front end of the upper outer surface of the fixing block 10. The support rods 6 pass through the through holes 11, and the outer wall of the support rods 6 is slidably connected to the through holes 11. The guide hole 12 is opened in the middle of the front outer surface of the fixing block 10. The pressing rod 13 passes through the guide hole 12, and the outer wall of the pressing rod 13 is slidably connected to the guide hole 12. The first mounting cavity 14 is opened in the middle of the fixing block 10, and the guide hole 12 passes through the first mounting cavity 14. The first mounting cavity 14 is opened inside the rear end of the fixing block 10, and one end of the guide hole 12 communicates with the second mounting cavity 17. The two sets of connecting holes 20 are opened in the through holes 11, pins 19, and connecting holes 20. Between hole 11 and second mounting cavity 17; connecting rod 18 is slidably installed in second mounting cavity 17, two sets of pins 19 are fixedly installed at the left and right ends of the front end outer surface of connecting rod 18, the outer wall of pin 19 is slidably connected to connecting hole 20, and the outer wall of one end of pin 19 is inserted into limiting hole 7; limiting block 15 and compression spring 16 are both located in first mounting cavity 14, limiting block 15 is fixedly installed on the outer wall of pressing rod 13, compression spring 16 is movably sleeved on the outer wall of pressing rod 13, and compression spring 16 is fixedly installed between the rear end outer surface of limiting block 15 and the rear end of first mounting cavity 14, the outer wall of limiting block 15 is slidably connected to first mounting cavity 14, and the rear end outer surface of limiting block 15 is elastically connected to the rear end of first mounting cavity 14 through compression spring 16.

The waist support plate 1, head support plate 2, connecting frame 3, first strap 4, and second strap 5 described herein are all prior art and can be readily understood by those skilled in the art; therefore, they will not be elaborated further. See the attached specification. Figure 1 As shown, at this time, the pin 19 in the locking structure 9 passes through the limiting hole 7 in the support rod 6. When it is necessary to adjust the distance between the head support plate 2 and the waist support plate 1, press the pressing rod 13. The pressing rod 13 drives the limiting block 15 to squeeze the compression spring 16 in the first mounting cavity 14. The pressing rod 13 drives the connecting rod 18 to move along the second mounting cavity 17. The connecting rod 18 drives the pin 19 to move along the connecting hole 20, so that one end of the pin 19 moves out of the through hole 11, so that the pin 19 is separated from the limiting hole 7. Then, lift or press down the head support plate 2, so that the support rod 6 moves up and down along the through hole 11. After reaching the desired position, release the pressing rod 13. Due to the reaction force of the compression spring 16, the pin 19 moves along the connecting hole 20, so that one end of the pin 19 is inserted into another set of limiting holes 7, thereby limiting the support rod 6. This is convenient for operation and easy to adjust the distance between the head support plate 2 and the waist support plate 1, improving applicability.
