The lower ball end surface of the second double-ball head rod 312 is tangent to the ball end surface of the first double-ball head rod 37, the ball end surface of the first double-ball head rod 37 away from the second double-ball head rod 312 is tangent to the ball end surface of the single-ball head rod 38, the upper ball end surface of the second double-ball head rod 312 is tangent to the outer surface of the cam 314, and in the initial state, the convex part of the cam 314 is located on the side of the second double-ball head rod 312, making the overall structure design reasonable and preventing the components from interfering with each other during operation, further ensuring the performance of the overall device.
[0027] Working principle: When actually laying cable conduits, just pass the cable through the holes on the conduit box 1. When connecting the conduit box 1 to the conduit box 1, the annular insert block 22 on one conduit box 1 will insert into the gap between the rubber ring 21 and the side wall of the conduit box 1 on the other conduit box 1, and then connect the two conduit boxes 1 with bolts, causing the trapezoidal slider 24 sliding inside the conduit box 1 to slide towards the auxiliary block 23. The trapezoidal slider 24 uses its inclined surface to push the auxiliary block 23 towards the rubber ring 21, and the inclined surface of the auxiliary block 23 is used to expand the rubber ring 21, further reducing the gap between the rubber ring 21 and its corresponding annular insert block 22, and improving the overall sealing performance.
[0028] When actually using the trapezoidal slider 24 to adjust the position of the auxiliary block 23, pull up the extension rod 32 that moves on the fixed seat 316. Since the fixed seat 316 is fixed on the turntable 31, the fixed seat 316 can be used to drive the turntable 31 to rotate on the conduit box 1. The lead screw 33 is fixedly connected to the turntable 31. Two annular gears 34 and two reversing gears 35 are arranged between the two lead screws 33. The two annular gears 34 are respectively fixed on the two lead screws 33, and the two reversing gears 35 mesh with each other, and a single reversing gear 35 only meshes with a single annular gear 34. Therefore, when one lead screw 33 rotates, the other lead screw 33 will rotate in the opposite direction. The two trapezoidal sliders 24 that slide inside the conduit box 1 and are respectively threadedly connected to the two lead screws 33 rotate along with the lead screws 33, and the two trapezoidal sliders 24 will slide towards each other to achieve the purpose of pushing the auxiliary block 23.
[0029] During the process of pulling up the extension rod 32, the convex part of the cam 314 fixed on the extension rod 32 contacts the second double ball head rod 312 sliding on the turntable 31, and squeezes the second double ball head rod 312 downward. Then the first double ball head rod 37 will slide towards the single ball head rod 38 to squeeze the single ball head rod 38 downward. At this time, the connecting block 310 fixed at the lower end of the single ball head rod 38 and the friction ring 311 fixed on the connecting block 310 slide downward. The friction ring 311 does not contact the conduit box 1, and the anti-slip lines for enhancing friction on the friction ring 311 no longer cooperate with the conduit box 1. At this time, the extension rod 32 can be used to drive the lead screw 33 to rotate, thereby adjusting the position of the auxiliary block 23 to improve the sealing degree. After releasing the extension rod 32, under the combined action of the cam 314 fixedly connected to the extension rod 32 and the fixed seat 316 at both ends, the second spring 313 fixedly connected to the second double ball head rod 312 and the turntable 31 at both ends, and the first spring 39 fixedly connected to the lead screw 33 and the single ball head rod 38 at both ends, each structure returns to the initial state. At this time, the friction ring 311 contacts the conduit box 1 again, and its anti-slip lines cooperate with the conduit box 1 to limit the rotation of the lead screw 33 and further limit the state of the rubber ring 21.

The scope of the present utility model is defined by the appended claims and their equivalents.
