[0038] Second Embodiment

[0039] Please refer to the following: Figure 3 , Figure 4 , Figure 5 and Figure 6 Based on the positioning chute for tumor radiotherapy provided in the first embodiment of this application, the second embodiment of this application proposes another positioning chute for tumor radiotherapy. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0040] Specifically, the second embodiment of this application provides a positioning chute for tumor radiotherapy, which is different in that the positioning chute for tumor radiotherapy has two sides of the inner wall of the second moving groove 5 with locking holes 10, and a connecting hole 11 is provided in the middle of one side of the surface of the connecting block 63. An elastic device 13 is provided inside the connecting hole 11, and a limit device 12 is slidably installed on both sides of the outer surface of the elastic device 13.

[0041] The elastic device 13 includes a fixed plate 131, a sliding rod 132, a limiting block 133, and a spring 134. The fixed plate 131 is fixedly installed in the middle of the inside of the communicating hole 11. The sliding rod 132 is fixedly connected to the middle of the fixed plate 131. The two limiting blocks 133 are respectively fixedly installed at both ends of the sliding rod 132. The two springs 134 are respectively sleeved on both sides of the outer surface of the sliding rod 132.

[0042] The limiting device 12 includes a pressing plate 121, an opening hole 122, a limiting cavity 123, and a locking block 124. The pressing plate 121 is sleeved on the outer surface of the slide rod 132. The opening hole 122 is opened in the middle of one side of the pressing plate 121. The limiting cavity 123 is opened in the middle of the inside of the pressing plate 121. The locking block 124 is fixedly installed on the other side of the surface of the pressing plate 121.

[0043] The card holes 10 are arranged in pairs, and there are multiple sets. The two card holes 10 in each set are respectively opened on both sides of the inner wall of the second moving groove 5.

[0044] The working principle of the positioning groove for tumor radiotherapy provided by this utility model is as follows:

[0045] When in operation, the user first holds the connecting rod 65 and rotates it through the second moving groove 5. The locking block 124 on the surface of the connecting block 63 is squeezed into the interior of the connecting hole 11 by the squeezing force. The locking block 124 drives the squeezing block 121 to move and squeezes the spring 134.

[0046] When the connecting hole 11 on the surface of the connecting block 63 rotates to align with the next locking hole 10, the restoring force of the spring 134 pushes the pressing plate 121 to move, and the pressing plate 121 drives the locking block 124 to be embedded into the interior of the locking hole 10 to achieve a limiting effect.

[0047] Compared with related technologies, the positioning groove for tumor radiotherapy provided by this utility model has the following beneficial effects:

[0048] This invention provides a positioning slide for tumor radiotherapy. By opening multiple locking holes 10 on the surface of the second moving groove 5, the elastic device 13 pushes the limiting device 12 into the inside of the locking holes 10, thereby limiting the position of the radiotherapy device 6. After the medical staff adjusts the angle of the radiotherapy device 6, it will automatically limit the position and keep the radiotherapy device 6 in the radiotherapy position. There is no need for the medical staff to continuously pull the connecting rod 65, which reduces the labor intensity of the medical staff and improves the practicality of the device.
