The bottom end of the rotating rod 31 is integrally formed with a raised baffle, and the direction of the pressure block 32 is determined by the direction of the baffle, so that the self-resetting driving rack 33 on one side can be accurately driven to move;

[0037] A tooth groove 22 is provided inside the bottom end of the drainage line fixing member 2, and a one-way transmission gear set 34 is meshed with the self-resetting driving rack 33 and the tooth groove 22;

[0038] A wedge-shaped spring latch 4 is arranged inside the drainage wire clamp 1 , and the wedge-shaped spring latch 4 is movably engaged with the tooth groove 22 .

When the support rod 21 moves upward, the tooth groove 22 and the inclined surface at the bottom of the wedge-shaped block 43 abut against each other, squeezing the wedge-shaped block 43 inward, so that the support rod 21 can move up smoothly. After the support rod 21 moves up to its position, the top horizontal surface of the wedge-shaped block 43 is engaged with the tooth groove 22, so that the support rod 21 cannot move down, thereby achieving a stuck fixation.

[0044] A slide groove 16 is formed on the outer surface of the casting shell 11 , and a slide rail 48 is fixedly connected to the interior of the slide groove 16 . The connecting arm 42 and the locking spring 47 are movably sleeved on the outer surface of the slide rail 48 .

[0048] The working principle is: by holding the handle 12, clamp the index finger and the middle finger on the outer surface of the bottom end of the rotating pull rod 31, and at this time, insert a set of drainage line ends into one side of the T-shaped lock head 15, and ensure that the blocking piece at the bottom end of the rotating pull rod 31 faces the drainage line end, and then use the index finger and the middle finger to pull the rotating pull rod 31 to move downward, at this time, the rotating pull rod 31 moves downward, and the sliding member 331 on this side is pressed downward by the pressing block 32, so that the lifting spring 336 is compressed, and at the same time drives the tooth plate 332 to move downward, and the tooth plate 332 drives the driving gear 343 to rotate, and the driving gear 343 drives the passive gear 342 to rotate through the ratchet 344 and the pawl 345, and the passive gear 342 meshes with the tooth groove 22, driving the support rod 21 to move upward, so that the support rod 21 moves upward, and the tooth groove 22 is against the inclined surface at the bottom of the wedge block 43, and the wedge block 43 is squeezed inward, so that the support rod 21 can move up smoothly;

[0049] The cam 332 is pressed against the locking cam 334 to lock the locking cam 336, and the locking cam 333 is pressed against the locking cam 334, thereby locking the locking cam 336 in the locking cam 336.

[0050] Then rotate the rotating pull rod 31 180 degrees, so that the pressing block 32 rotates to the top of the sliding member 331 on the other side, and then place another set of drainage wire ends on the inner bottom of the other side of the T-shaped lock 15, and then repeatedly pull the rotating pull rod 31, so that another set of trapezoidal locking blocks 23 fix the other set of drainage wire ends, thereby quickly fixing the two sets of drainage wire ends and realizing double-wire live operation;

[0051] After use, the two sets of sliders 41 are pressed toward the middle so that the locking spring 47 and the auxiliary spring 46 are compressed. At this time, the wedge-shaped block 43 is moved out from the inside of the tooth groove 22. At this time, the support rod 21 automatically slides down to the bottom under the action of gravity, and at the same time drives the passive gear 342 to rotate in the opposite direction. The passive gear 342 drives the pawl 345 to reverse. At this time, the pawl 345 does not transmit with the ratchet 344, and the driving gear 343 will not be selected, thereby realizing the rapid unlocking of the two sets of drainage line ends.
