Specifically, when the inflatable sealing plug 35 is opened, the chute 27 can be continuously inflated through the inflation channel 36, the gas continuously entering the chute 27 forms high pressure, the gap 40 is gradually expanded through the bell mouth, the gas in the chute 27 enters the sealed chamber and presses the limiting plate 23, the bottom of the gap 40 is not provided with the bell mouth, the gap 40 can be further extruded when the gas in the sealed chamber forms high pressure, the gas in the sealed chamber cannot leak, and the upper sealing ring 37 on the inner wall of the upper end of the casing 38 prevents the gas entering the chute 27 from leaking from the upper end of the casing 38.
This embodiment provides a telescopic cable built on stilts cradling piece, the working process as follows:
when the cable needs to be stably supported, the first rotating button 6 can be screwed and tightly pressed and fixed on one side of the telescopic rod 12, and the distance between the clamping plate 10 and the rack rod 1 is fixed;
when needing to carry out elastic support to the cable, screw first knob 6 and compress tightly when fixing in expansion sleeve 17 one side with it, expansion link 12 is the expansion sleeve 17 flexible relatively, reach the relative hack lever 1's of splint 10 apart from adjustable purpose, at this moment, the cable is when being held by the interlock between a pair of splint 10, the cable receives gravity or other when drawing the power of holding, the cable can oppress the expansion link 12 of splint 10 bottom and stretch out and draw back in order to carry out elastic support to the cable relatively to the expansion sleeve 17, offset the cable and receive the stress of bearing and the gravity of exerting for hack lever 1 with the cable.
When the sealed chamber is inflated, the air continuously filled into the sealed chamber pushes the inserted rod 15 to vertically move along the casing 38 so as to be inserted into the ground, so that the phenomenon that the inner diameter of the hole is easily increased and unstable when the hole is obliquely inserted into the bottom surface is avoided, and when the sealed chamber in the casing 38 is continuously inflated, the inserted rod 15 can be further pressed and fixed on the ground, so that the structure is stable.
It should be understood that the present invention is not limited to the particular embodiments described herein, but is intended to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
