Problems solved by technology
[0004] This kind of radiometer uses a hydraulic lifter to push the rotating shaft up and down, and then drives the suspension arm to go up and down. Therefore, this kind of radiometer requires a special hydraulic mechanism to meet the needs of the work. The hydraulic mechanism is not only complicated in structure, but also high in production costs. , and the maintenance cost is also increased in the daily work and maintenance process, which is not conducive to the user's use

Description
technical field [0001] The invention relates to the technical field of injection molding, in particular to a radiometer. Background technique [0002] Medical personnel often need to use radiographs when treating tumor patients, such as the treatment of nasopharyngeal cancer and cervical cancer. In these cases, radiographs can be used to obtain good therapeutic effects. At present, most of them use traditional radiographs. The radiation range and body position adjustment of the traditional radiometer cannot fit the treatment well, and the operation requires a high degree of professionalism, which adds great difficulty to the medical staff. [0003] The utility model patent with the publication number CN204502132 discloses a new type of radiometer, which includes a main body of the radiometer and an operation console. A hydraulic lifter is arranged on the main body of the radiometer. A suspension arm is provided, and an emitter hook is arranged on the suspension arm. An emit...
