[0029] like Figure 4 、 Figure 6 、 Figure 5 The technical solution shown, in order to solve the problem that the fixed block is prone to falling due to swinging during operation, discloses: the fixed rod 3 is fixedly connected to the rotating plate 18, and the trigger plate 20 is rotatably installed inside the sixth inner groove 19, and the rotating plate 18 is fixedly connected to the first inner groove 6 through the end of the trigger plate 20 to form a transmission structure, the fixed block 4 is fixedly connected to the hanging ring 5, and the hanging ring 5 is equidistantly installed on the top of the fixed block 4 in four groups about the center point of the fixed block 4, and the fixed rod 3 passes through the positioning ring 13 and then through the second inner groove 10 to complete the fixation, the outer surface of the fixed rod 3 contacts the inner surface of the positioning ring 13 to form a sliding structure, and the outer surface of the fixed rod 3 contacts the inner surface of the second inner groove 10 to form a sliding structure, and the fixed rod 3 is equidistantly installed in four groups about the center point of the syringe 1.

[0030] When it is necessary to fix the fixing block 4, place the fixing block 4 inside the syringe 1, align the fixing rod 3 with the position of the positioning ring 13 and move it horizontally inward. After the fixing rod 3 passes through the positioning ring 13, it continues to push forward until it enters the second inner groove 10. After the fixing rod 3 enters the second inner groove 10, the rotating plate 18 fixed on the outer surface of the fixing rod 3 at the front end of the fixing rod 3 contacts the trigger plate 20 rotatably installed inside the sixth inner groove 19.
