[0025] By adopting the above technical solution, when performing bone density testing on the arm, the arm is passed through the interior of the fixing frame 64, and the motor 61 is turned on. The motor 61 drives the bidirectional screw 63 to rotate through the output end. The rotation of the bidirectional screw 63 drives the two groups of nut blocks 62 to approach each other. The two groups of nut blocks 62 approach each other and drive the two groups of fixing frames 64 to approach each other, thereby positioning and fixing the arm.

[0026] Specifically, the guide assembly 65 includes a guide rod 651 and a slider 652. The other side of the lower end of the fixing frame 64 is provided with a slider 652 inside another group of mounting grooves 66. The guide rod 651 is provided inside the slider 652.

[0030] When this embodiment is in use, when performing bone density testing on the arm, the arm is passed through the interior of the fixing frame 64, the motor 61 is turned on, and the motor 61 drives the bidirectional screw 63 to rotate through the output end. The rotation of the bidirectional screw 63 drives the two groups of nut blocks 62 to approach each other. The two groups of nut blocks 62 approach each other and drive the two groups of fixing frames 64 to approach each other, thereby positioning and fixing the arm. When the fixing frame 64 slides, it drives the slider 652 to slide on the surface of the guide rod 651, thereby improving the stability of the sliding process of the fixing frame 64. When the two groups of fixing frames 64 approach each other, they drive the positioning rod 653 to be inserted into the interior of the positioning hole 654, thereby improving the firmness of the fixing frame 64 after installation.

When the clamping block 25 on the side of the dustproof plate 26 is inserted into the clamping slot 21, the adjustment block 233 is released, and the spring 231 rebounds, thereby driving the fixing rod 234 to insert into the fixing hole 24 to fix the dustproof plate 26.

[0037] The working principle and use process of the utility model: when the utility model is used, when the bone density of the arm is tested, the arm is passed through the interior of the fixing frame 64, the motor 61 is turned on, and the motor 61 drives the bidirectional screw rod 63 to rotate through the output end, and the rotation of the bidirectional screw rod 63 drives the two groups of nut blocks 62 to approach each other, and the two groups of nut blocks 62 approach each other and drive the two groups of fixing frames 64 to approach each other, so as to position and fix the arm, and when the fixing frame 64 slides, it drives the slider 652 to slide on the surface of the guide rod 651, so as to improve the stability of the sliding process of the fixing frame 64, and when the two groups of fixing frames 64 approach each other, it drives the positioning rod 653 to be inserted into the interior of the positioning hole 654, so as to improve the firmness of the fixing frame 64 after installation; through the heat dissipation fan 22 The setting can improve the heat dissipation efficiency of the bone densitometer. When the cooling fan 22 needs to be cleaned, the adjustment block 233 inside the sliding adjustment slot 232 is driven by the adjustment block 233 to slide the fixing rod 234 out of the fixing hole 24. At this time, the dustproof plate 26 can be opened to clean the cooling fan 22. When the dustproof plate 26 needs to be installed, the adjustment block 233 inside the adjusting slot 232 is slid again. The adjustment block 233 drives the fixing rod 234 to compress the spring 231 and embed it into the top seat 3. When the clamping block 25 on the side of the dustproof plate 26 is inserted into the clamping slot 21, the adjustment block 233 is released, and the spring 231 rebounds, thereby driving the fixing rod 234 to insert into the fixing hole 24 to fix the dustproof plate 26.
