The top of the placement groove 2 102 is fixedly connected with a circular groove 104, and a limiting groove 105 is opened inside the circular groove 104. The number of the placement grooves 2 102 is set to five, and the five placement grooves 2 102 are adjacently distributed from top to bottom on the right side of the placement groove 1 101, and the difference in length between two adjacent placement grooves 2 102 is the same, and the bottom ends of the five placement grooves 3 103 are interconnected with the installation groove of the placement controller 9.

In the above embodiment, it should be noted that the five placement slots 2 102 are equidistantly distributed and are distributed along a trapezoid so that the photoelectric sensor 305 can be freely adjusted within each independent interval, thereby achieving better distance adjustment and adapting to automatic stop control of different injection volumes. In addition, the placement slot 2 102 and the placement slot 1 101 are used to better limit the objects lifted and lowered inside the photosensitive transmission device 3 to prevent them from rotating and deviating.

Example 2

As shown in Figures 1 and 4, a radioactive drug labeling device includes all the contents of Example 1. In addition, the photosensitive transmission device 3 includes a rotating column 301, a transmission column 302 is integrally formed at the bottom end of the rotating column 301, a limit ring 303 is fixedly installed on the upper end of the transmission column 302, the transmission column 302 is rotatably installed inside the circular groove 104 through the limit ring 303, a transmission block 304 is threadedly installed on the bottom end of the transmission column 302, a photoelectric sensor 305 is fixedly connected to the right end of the transmission block 304, a wire 2 306 is fixedly connected to the left end of the transmission block 304, the width of the photoelectric sensor 305 is adapted to the width of the placement slot 1 101, the transmission block 304 is slidably installed inside the placement slot 2 102, the bottom ends of the wires 2 306 are fixedly connected to the top of the controller 9, and the photoelectric sensor 305 and the controller 9 are electrically connected to each other through the wires 2 306.

Working principle: according to the actual injection volume requirement each time, the rotating column 301 is rotated to adjust the photoelectric sensor 305 to the appropriate position, so that the distance between each two photoelectric sensors 305 is exactly the same as the preset injection volume requirement, and then the motor 11 is started to drive the stud 12 to rotate, and the lifting seat 13 drives the clamping seat 8 to descend so that the piston 7 starts to push and inject. When the protruding part connected between the lifting seat 13 and the clamping seat 8 slides inside the sliding groove 4, the first photoelectric sensor 305 is blocked. The photoelectric sensor 305 receives the signal and transmits it to the inside of the controller 9 through the wire 2 306. The wire 10 is used to send a signal to the motor 11 to stop it, and the piston 7 stops pushing and injecting, realizing automatic stop.
