The contact surface of the left pull block and the right pull block is provided with a magnetic sheet (not shown in the figure), so that after the pedal is released, the left pull block and the right pull block are beneficial to quickening the closing of the opening.

After the pedal 17 is released by the foot, the left pull block and the right pull block are still in a separated opening barrel cover state, the lower end of the notch 14 on the outer side of the barrel body is provided with a flaring 29 (the notch is L-shaped), the upper part of the flaring is provided with a circular limiting groove 31, the limiting groove is smoothly connected with the upper part of the notch by a circular arc-shaped clamping body 32, the width of the clamping body is one fourth of the diameter of the lever (the radius of the common control clamping body is 1-2 mm), the depth of the limiting groove can at least accommodate the cross section of one third of the diameter of the lever, when the pedal is operated, the foot is pressed downwards, the end of the lever extending out of the barrel body moves downwards to drive the connecting rod 12 to move downwards, the left pull block and the right pull block move towards each other to drive the telescopic strip to be contracted, so as to open the upper opening of the barrel body, medical waste is collected in time, when the end of the lever extending out of the outer side of the barrel body starts to enter the upper position of the flaring, the foot of an inclined plate 30 (60 degrees with the level) of the foot of an operator applies a little transverse force to the right, the foot of the pedal slides in the horizontal plane into the limiting groove, the foot is limited in the limiting groove, the foot is opened in the limiting groove, the opening of the foot is at least, and the opening is still in a state when the opening is still open, and the upper end of the opening is still is opened. That is, after the feet are loosened (or the people leave), the upper opening of the barrel body can still be in an open state. The foot of the operator presses the pedal downwards and applies point force to the sloping plate at the left side, so that one end of the lever descends a small section and slides across the clamping body in the horizontal direction to withdraw from the limiting groove, after the foot releases the pedal, one end of the lever moves up to the upper end of the notch under the action of the return spring and the torsion spring, and the left pull block and the right pull block relatively move to drive the telescopic strip to be unfolded, so that the opening at the upper end of the barrel body is closed (which is equivalent to the state that the cover body is still closed).

In the figure, the opening 28 is rectangular, the sum of the moving distances of the left pull block and the right pull block is the opening width of the barrel body, the barrel body is placed on the ground at the lower part of the special bed for the lithotomy position examination, the total height of the barrel body (the height of waste materials contained in the barrel body and the space height of the inner cavity at the lower end of the barrel body) is smaller than the height of the special bed board for the lithotomy position examination from the ground, and in order to make the opening on the barrel body more, the barrel body design meets the following conditions at the same time: firstly, the opening width of the barrel body is small, secondly, the compression length of the maximum compression return spring of the lever at the lower layer of the barrel body is large, namely the downward movement distance of the pedal at one end of the lever extending out of the outer side surface of the barrel body is large (the space height of the inner cavity at the lower end of the barrel body is large).

For example, if the tub opening is designed to be rectangular with a length and width of 500×200 or 400×200 mm. If the height of the bed plate from the ground is 660 mm, the total height of the barrel body is 640 mm, the height of the inner cavity of the barrel body is 500 mm, namely the height of the inner cavity space of the lower end of the barrel body is 140 mm, namely the maximum distance of the actual descending of the pedal is 130 mm, when the width of the half edge of the opening of the barrel body is 100 mm, the distance from the movable ball joint 33 to the connecting rod is 30 mm, when the actual descending distance of the pedal is 130 mm, calculated according to the principle of a similar triangle, the respective moving distances X of the left pull block and the right pull block can be calculated according to the following formula, 30/X= (30+100)/130, X=3900/130 is 30 mm, so that the connecting rod moves up and down under the leverage, namely the moving distances of the left pull block and the right pull block are 30 mm, namely the moving distances of the inner cavity space of the lower end of the barrel body are 140 mm, namely when the width of the opening of the upper end of the barrel body is 200 mm, the opening can be opened by 60 mm, and the opening part (about one third) can be opened only. That is, the opening at the upper end of the barrel in the above example is only partially opened after being closed, and the width of the opening is determined according to the space height of the inner cavity at the lower end of the barrel. If the opening at the upper end of the barrel body is opened more, the space height of the inner cavity at the lower end of the barrel body is increased, and the height of the charging inner cavity of the barrel body is reduced.
