The cooperation between the connecting seat 85 and the support seat 81 can limit the patient's hands and feet to prevent the patient's movement from affecting the radiotherapy effect.

[0025] Embodiment 2:

[0026] See also Figure 1 , Figure 2The radiotherapy equipment includes a positioning mechanism and a base plate 1. A radiotherapy chamber 2 is fixedly installed on the top of the base plate 1. A fixing plate 3 is fixedly installed on the front end of the radiotherapy chamber 2. A supporting base 4 is arranged at the front end of the fixing plate 3. A supporting base 5 is arranged at the upper end of the supporting base 4. A treatment bed plate 6 is slidingly arranged inside the supporting base 5. The treatment bed plate 6 is slidingly connected to the radiotherapy chamber 2. A plurality of slide seats 11 are slidingly sleeved inside the treatment bed plate 6. A protective cover 7 is fixedly connected to the upper end of the slide seat 11. A handle 10 is fixedly connected to the top of the protective cover 7. An adjustment and protection mechanism 9 is arranged on the treatment bed plate 6. A supporting seat 81 is fixedly installed inside the treatment bed plate 6.

[0027] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 The adjusting and protecting mechanism 9 comprises a slide groove 91. The inside of the treatment bed plate 6 is provided with a slide groove 91. The inside of the slide groove 91 is slidably connected with a ball 92. The ball 92 is movably sleeved in the inside of the slide seat 11. The inside of the slide seat 11 is provided with a first spring 93. One end of the first spring 93 contacts the ball 92. The other end of the first spring 93 is fixedly connected to the slide seat 11. By designing the first spring 93, the force of the first spring 93 can act on the ball 92. The inside of the slide seat 11 is slidably sleeved with a protrusion 94. The protrusion 94 is slidably connected to the treatment bed plate 6. The inside of the protrusion 94 is slidably sleeved with a fixing rod 95. The fixing rod 95 is fixedly connected to the treatment bed plate 6.

[0028] The specific implementation process of the utility model is as follows: when in use, under the action of the shield 7, part of the patient's body can be shielded and protected to prevent the unnecessary treatment part from being irradiated. When it is necessary to adjust the position of the shield 7, the handle 10 is pushed horizontally, and the handle 10 drives the shield 7 to move. The shield 7 drives the slide 11 to slide along the treatment bed plate 6, and the ball 92 slides along the slide groove 91. At the same time, the slide 11 and the protrusion 94 slide relative to each other, and the slide 11 will squeeze the protrusion 94, and the protrusion 94 will slide along the fixed rod 95. At the same time, the protrusion 94 squeezes the second spring 96, which can separate the protrusion 94 from the slide 11. As the slide 11 slides, when it moves to the protrusion 94 at another position, the protrusion 94 can be inserted, and the position of the slide 11 can be adjusted and fixed, thereby facilitating the adjustment of the position of the shield 7 and facilitating shielding and protection of different positions of the body. By pulling up the handle 10, the handle 10 drives the shield 7 and the slide 11 to move upward, and the slide 11 drives the ball 92 to move upward along the slide groove 91. The ball 92 will slide toward the inside of the slide 11 to squeeze the first spring 93, so that the ball 92 can slide out of the slide groove 91. The shield 7 is easy to disassemble and install, and different numbers of shields 7 can be equipped according to actual needs.
