Referring to Fig. 1 to 5, it is provided with the second elastic element 180 between the second runner 60 and second bearing component 122, second Elastic element 180 is supported with the second runner 60 and second bearing component 122 respectively, in the present embodiment, the second elastic element 180 For but be not limited to spring, be elastically compressed between the second runner 60 and second bearing component 122, the second elastic element 180 pair of second runner 60 generates axial pretightning force, to guarantee the second confined planes 205 of transmission shaft 20 and the table of the second runner 60 There is enough compactnesses between face, be in close contact the joint surface of transmission shaft 20 and the second runner 60 and there is enough frictions Power is free to prevent the second runner 60 second runner 60 when being not affected by external force (driving force applied to the second runner 60) effect Rotation.

Specifically, one end of the second elastic element 180 is resisted against the second runner 60 by a gasket 190, and the other end passes through Another gasket 190 is resisted against the stop bit bearing 124 of second bearing component 122, in this way, it is convenient for the installation of the second elastic element 180, And structure is more firm.

The water discharge control method provided by the embodiment of the utility model using above-mentioned water trap 100 is made with reference to the accompanying drawing It is described in detail.

Operating assembly 80 is driven to separate and make castle wheel 70 and the first runner 50 to engage with the second runner 60 castle wheel 70 Connection controls the rotation of the second runner 60 by operating assembly 80, with on-off channel 303.In the present embodiment, behaviour is rotated clockwise Make nut 801, operating nut 801 drives reversing shaft 802 and opposite transmission shaft 20 moves together with the fixed castle wheel 70 of reversing shaft 802 It is dynamic, so that castle wheel 70 is made to separate with the second runner 60 and engage with the first runner 50, its telescopic rod after electric pushrod 901 is powered It stretches out, the push rod cup 902 being connected on the telescopic rod pushes the rotation of the first runner 50, to make 70 turns of castle wheel be engaged with It is dynamic, while castle wheel 70 rotates, drives transmission shaft 20 and spool 302 to rotate, realize the automatic control of spool 302.

Operating assembly 80 is driven to separate and make castle wheel 70 and the second runner 60 to engage with the first runner 50 castle wheel 70 Connection drives the second runner 60 to rotate, with on-off channel 303.In the present embodiment, rotation process nut 801 counterclockwise, operation Nut 801 drives reversing shaft 802 and with the fixed castle wheel 70 of reversing shaft 802 together relative to the movement of transmission shaft 20, to make clutch Wheel 70 is separated with the first runner 50 and engage with the second runner 60, stirs handle 141 and the second runner 60 is pushed to rotate, thus make and The castle wheel 70 of engagement rotate, while castle wheel 70 rotates, drive transmission shaft 20 and spool 302 to rotate, realize spool 302 manually control.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modification, equivalent replacement or improvement etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
