[0033] Annular sleeve 401 is rotatably sleeved in the recess, and pneumatic movable plate 403 is installed on the inner side of annular sleeve 401, and pneumatic movable plate 403 contacts the inner wall of the recess.

[0034] Through the lap joint of the transmission frame 4 by its own gravity, and through monitoring the change of air pressure in the cavity formed between the base 3 and the transmission frame 4, the control speed difference of the coiled tubing 5 between the injection head and the unwinding between the winding drum 6 can be reacted in real time, which provides effective data for the unwinding of the coiled tubing 5, and the air pressure sensor 404 is connected with a data display device and a buzzer, which reminds the abnormal injection of the coiled tubing 5 and can stop in time to avoid greater loss.

[0035] Please refer to Figures 1 to 5 The outer side of the monitoring base 3 is provided with a through hole, and the cavity is connected with the outside through the through hole, and a screw plug 301 is detachably installed in the through hole.

[0036] Through the action of the screw plug 301, the cavity is sealed, and the air pressure in the cavity can be accurately controlled through the through hole connected with the equipment, so as to realize the control effect of the transmission frame 4 on the down pressure of the coiled tubing 5.

[0037] Through the separation of the air pressure fixing plate 405, the separation of the ring structure can be realized, the smooth generation of air pressure is ensured when the transmission frame 4 rotates, and the monitoring is more accurate through the monitoring of the two air pressure sensors 404.

[0038] Please refer to Figures 1 to 5 The transmission frame 4 further comprises a linkage frame 402 and a down pressure ring frame 406.

[0039] The linkage frame 402 is installed on the outside of the annular sleeve 401, the down pressure ring frame 406 is installed on the linkage frame 402, and the coiled tubing 5 passes through the middle of the down pressure ring frame 406.

[0040] When the transmission frame 4 rotates, the air pressure movable plate 403 moves at this time, and through the cooperation between the air pressure fixing plate 405 and the air pressure movable plate 403, the change of air pressure can be smoothly generated.
