Detailed Description

The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be seen from fig. 1 to 3, the present invention includes a thick-walled tube 1 with a horizontal axis in the front-back direction, an upright column 2 perpendicular to the thick-walled tube 1 is disposed at the upper end of the thick-walled tube 1, a shift lever 3 is hinged to the upper end of the upright column 2, an arc-shaped mounting seat 4 with a hinge shaft of the shift lever 3 on the upright column 2 as a center of a circle is fixed at the lower end of the shift lever 3, two through holes with the shift lever 3 as a symmetry axis are disposed on the mounting seat 4, a porous plate 5 is detachably mounted in the through holes, a mounting groove 6 for the mounting seat 4 to pass through is disposed on the thick-walled tube 1, a stopper 7 is disposed on each of the left and right sides of the shift lever 3, the shift lever 3 contacts with the stopper 7 on one side to enable the through hole on the mounting seat 4 on the side to be coaxial with the thick-walled tube 1, a positioning pin 8 is disposed at the upper end of the shift lever 3, a spring 9 is fixed on the positioning pin 8, and the free end of the spring 9 is fixed at the upper end of the thick-walled tube 1.

For the reinforcement of the thick-walled pipe 1, the thick-walled pipe 1 is provided with an extension fixing portion 10 at the lower end of the installation groove 6.

In order to fix the device and the extruder, one end of the thick-wall pipe 1 is provided with a flange.

In order to realize the installation of the installation groove 6 and the installation seat 4, the width of the installation groove 6 is consistent with that of the installation seat 4, the bottom of the installation groove 6 is arc-shaped with a hinge shaft of the deflector rod 3 on the upright post 2 as a circle center, and the installation groove 6 and the installation seat 4 are always attached to the wall in a sliding manner.

For the auxiliary positioning of the spring 9, the positioning pin 8 is always arranged above the hinge shaft of the shift lever 3 and the upright post 2, and the free end of the spring 9 is fixed on the whole upper end position of the thick-walled pipe 1.

The specific working process of the utility model is as follows: when the device is used, the driving lever 3 is pulled or driven to drive the mounting seat 4 to cling to the wall in the mounting groove 6 around the hinge shaft on the upright post 2 to slide, when the upper end of the driving lever 3 inclines to the left side, the driving lever 3 is attached to the left limiting block 7 at the moment, meanwhile, the left through hole on the mounting seat 4 is coaxial with the thick-walled tube 1, the spring 9 is in a stretched state at the moment, the upper end of the driving lever 3 can have the tendency of anticlockwise rotation around the hinge shaft of the upright post 2 under the reset action of the spring 9, but the left limiting block 7 is limited, so that the spring 9 and the limiting block 7 can ensure that the through hole on the left side of the mounting seat 4 and the thick-walled tube 1 are kept in a coaxial state, when a filter screen in the left through hole needs to be replaced, the driving lever 3 can rotate around the hinge shaft by clockwise driving the upper end of the driving lever 3, and the spring 9 is continuously stretched before the driving lever 3 rotates to the vertical state in the process, can make the pen-holder draw close and finally laminate to the stopper 7 on right side rapidly under spring 9's effect when driving lever 3 rotates to the upper end towards the right side, spring 9 still keeps having the shrink trend this moment to realize the through-hole and the thick walled pipe 1 coaxial positioning of mount pad 4 right-hand member, the left through-hole removes out the thick walled pipe 1 outside this moment, realizes the change to the filter screen in the through-hole in the outside.

The device has the remarkable advantages that: this device is stretched through spring 9 and is made driving lever 3 can be fast to corresponding the side movement at spring 9's pulling force after the slope of upper end, and this in-process spring 9 can assist the slip of drive installation piece in mounting groove 6, and the spring 9 remains behind driving lever 3 and contacts stopper 7 behind the stopper 9 the tensile force realize driving lever 3 spacing with stopper 7's the effect of blockking down simultaneously, can effectually prevent the location of losing of through-hole when filtering for this device uses safelyr and high efficiency.
