The inner lining is mounted on the bottom surface of the outer frame and can slide along the outer __. The two sides of the pivotal f4) are respectively pivotally connected to the inner ends of the two inner plates (52); the top surfaces of the two outer frames (9) are implanted on two sides of the base body (3). A pull rod (7) passes through the = two, and the other end of the pull handle (2) is connected to the pivot block (4). Two: and ί is disposed on the bottom surface of the inner panel (52) of the two clamp body (5), the rubber sponge (8) is long, and the length of the inflammation seat is long, so that the two ends of the rubber sponge protrude from the two clamp holders to injure the furniture. U W free dragging When the mop is in the state shown in the figure - figure, the rubber is ^== ground. If the second block is replaced by the second seat, the second clamp body (5) will be folded in half and the water will be squeezed to the bottom of the base. 5 should be, in order to glue the fourth picture, the mop body (5) is designed as a slip structure, the purpose of the basin is to _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Can be affected by the face. Move into the body of the body (7), use the sea area = the tow (four) financial class ship, fine, after the actual make f ^ seat 働 'to the base (3) within the double grass May, the first picture, in the ha In the structure, 兮-磕; is a vertical form, the distance between the two pivot points (8) at the top is 'the bottom end of the dry 2 3 201127334, the distance between the joints (4) and (5) is the same, and the two ends of each link (51) There is no any resistance, it is easy to swing left and right. Since the pivot block (4) and the three cool body (5) are bendable pivotal design, when the ground is dragged, when a force F is applied to the clamp seat, The force is located in the two-turn 'dimension', which will easily cause the two clamps (5) to move inwardly and the bottom end angular displacement of the two links (6), as shown by the imaginary line. (5) It is not easy to keep straight The state makes the mopping floor not smooth. Another deficiency of the conventional structure occurs during the process of extruding the rubber. Referring to the first figure, when the pull rod (7) pulls the clamp upward, the clamp (4) pulls the two inner plates (52) to cause the two clamps (3) to swing, and at the same time, the bottom ends of the two links (6) will be The lowest point (ie, the lowest position) is turned inward; during the process of the New (3), each inner panel (52) simultaneously slides within the outer frame (51). When the rubber (8) is squeezed, an elastic restoring force will be stored. At certain angles, for example, as shown in the third figure, the rubber will produce the maximum elastic force, since the inner plate (52) has not yet reached its displacement. At the end of the trip, the elastic force of the rubber will push the outer frame (9), causing the outer frame to slide outwards quickly and instantly, and produce a click sound, which is reached between the inner panel (52) and the outer frame (8). Due to the displacement stop point. The inflammatory body (5,) on the right side of the third figure shows that the inner plate (52,) slides outward and is in the state of displacement stop point. At this time, the right end of the rubberized cotton has been moved into the outer frame (51, Within the range of ); while the inner plate (52) of the left side clamp (5) has not yet reached the displacement stop point. During the operation of the extruded rubber sponge, the outer frame (51) (51,) on both sides will be quickly ejected outward, as shown in the fourth figure, and two clicks will be produced, which will easily lead to consumption of product quality. Poor misunderstanding. In addition, after the rubberized cotton is used for a long time, the physical properties are deteriorated, and the elastic force may be weakened to push the outer frame, which may cause the rubberized cotton to be completely unable to move into the folder. [Invention] The present invention aims to solve the above problem, and its main purpose is to The utility model provides a mop, wherein the bottom end of the mop is pivoted with a two-bar linkage and a bendable clamping seat. The invention enables the connecting rod of the mop to not be easily shaken in 201127334, so that the clamping seat can be stably maintained. . Another object of the present invention is to provide a mop having a slidable design that does not produce an acoustic sound when the mop of the mop is squeezed. In order to achieve the above object, the mop provided by the present invention comprises: a grip bar; a base fixed to the bottom end of the grip; a clip seat located below the base, having a pivot block and two splints, each The splint includes a fixed plate and a sliding plate, wherein the inner end of the sliding plate is respectively pivotally connected to the two sides of the pivoting block; the bottom surface of the sliding plate is provided with a rubber; the inner end of each of the sliding plates can be self-assembled The inner end of the fixing plate slides out, and the sliding plate has a sliding stop point. The two connecting rods are respectively pivotally connected to the two sides of the clamping seat, and the bottom ends thereof are respectively pivotally connected to the two fixing plates. When the pull handle provided on the grip bar is pulled, the clip holder can be moved to press the two splints to squeeze the rubber sponge, or the pivot block and the two splints are stretched in a straight state. When the clamping seat is in a straight state, the two connecting rods are inclined, and the bottom end pivotally closes the planting system to be larger than the nesting distance, and the outer sides of the two connecting rods abut against the two sides of the base. Thereby, the connecting rod has a positioning effect and does not easily shake, so that the clamping seat is more stable and is not easy to move into the base. In the process of extruding the rubber sponge, the present invention causes the slide plate to slide out of the fixed plate and reach its displacement stop point without causing a rapid bounce of the fixed plate. [Embodiment] In order to enable the reviewing committee to further understand the purpose, features, and advantages of the present invention, the following scales are preferred, and are illustrated in detail with reference to the drawings: The mop provided by this bribe (1G) - preferably implemented ^ 'mainly includes: - grip (2 〇), - pull handle (30), - base (40), two cups (50), a clip Seat (6〇) and a linkage rod (8 habits.

The top end (51) of each connecting rod (50) is located in the base (4〇), and the bottom end (55) is exposed outside the base. The clamping seat (60) has a pivot block. (62) and two plywoods (64), the inner sides of the two plywoods (64) are respectively pivoted on the pivot block (62) by a cymbal (65) Therefore, the clamping seat is a movable bending structure. Each of the clamping plates (64) includes a fixing plate (70) and a sliding plate (75). The fixing plate (70) has a lug (71) at the top end thereof. The bottom end of each connecting rod (5〇) is pivotally connected. Referring to the eighth figure, the bottom surface of the fixing plate (70) is further provided with a roadway (73) along the longitudinal direction thereof, and the two side walls of the rail are provided with fins ( 74), to limit the opening of the track. The inner end of the sliding plate (75) is provided with a splicing portion (76), and the top surface is provided with a molding strip (77), the cross section of the slat is narrow and narrow inside a four-button hole (66) is disposed on the sliding plate (75). The sliding plate (75) is engaged with the mounting plate (73) by the molding strip (77), such as In the nine-figure view, the sliding plate and the fixing plate are relatively slidable. The two clamping plates (64) are pivotally connected to the two connecting rods (50) by the fixing plate (70), and the two sliding plates (75) are pivotally connected. The portion (76) is connected to the pivot block (62). In addition, referring to the eighth, ninth, and eleventh drawings, each fixing plate (10) is provided with four elongated strip-shaped hollow holes (72), respectively The two sides of the track (73), and corresponding to the buttonhole (66). A rubber (80), elongated, with a top connection (82), and the buckle (66) of the top surface of the two connecting pieces (82) is fastened with the buttonhole (66) of the two clamping plates (64), as shown in the eleventh figure, so that the rubber sponge (8〇) The detachable design is installed on the bottom surface of the holder (60) to replace the rubber. The lugs of each connecting piece (82) are inserted into the slots (72) of the fixing plate (70). And each of the lugs (84) has a spacing from the 201127334 end wall (721) within each slot (72). The linkage rod (85) is preferably a u-shaped rod body passing through the through hole (46) of the top surface of the base (4〇), and the bottom end thereof is connected to the pivot block of the clamping seat (60). (62) the through hole =) is connected to the pivot block (62), and the top end is connected to the pull handle (10). When the pull handle is pulled, the clamp can be driven via the linkage rod (85) (6〇 ). :^ When using, 'pull the handle (30) downwards. As shown in the fifth figure, the holder (60) can be pushed out toward the bottom end of the seat (40) to make the pivot block (62) and the splint (64). The stretch is straight, and the rubber (80) is straight, so that the mop can be used to mop the floor. 1 Referring to the seventh and tenth views, when the holder (60) is stretched in a straight state, the distance between the pivotal points (ie, the pivots (56)) of the bottom ends of the two links (50) is (D) Greater than the distance between the top pivot joints (ie, the pivots (52)) (〇, such that the two links (5〇) are inclined, not vertical, and the longitudinal and vertical lines of each link (50) have An angle Θ having an angle of between 20 and 75 degrees, preferably between 25 and 45 degrees, such as 30 degrees. The bottom end of the two links (50) is inclined outwardly and outwardly The side faces abut against the inner wall surface of the bottom end of each seat portion (42). As shown in the seventh figure, an abutting portion (58) is in contact with the seat portion (42) on the outer side of each of the joints. The rod has a point of outward sin. When the mop (1〇) is used, the bottom end of the connecting rod (5〇) is not easy to swing inward, so that the seat body (60) is firmly maintained in a straight state, and is not easy. The ground is bent inward. Furthermore, as can be seen from the tenth figure, the bottom end of the connecting rod is located at the outer side of the vertical line (E) of the top pivot joint (pivot (52)). 56)) When the vertical line (E) has not been crossed inward, the connecting rod does not easily swing inward. Twelve, when you want to squeeze the rubber (80), pull up the handle (3〇) and pull the holder (60) into the space (44) of the base (40) via the linkage lever (85). The clamping plate (64) will swing 'with respect to the pivot block (62) and form a folded state. At this time, the two sliding plates (75) are slid in the fixed plate (70) and the inner end of the sliding plate (75) gradually becomes self-contained. The inner end of the solid plate (70) slides out, the inner end of the two links (50) is gradually displaced toward the inner angle, and the two plates (60) are gradually inclined. When the bottom end of the connecting rod (5〇) is twelfth When the status bit 201127334 moves to the lowest point shown in the thirteenth figure, the slide plate p5) has reached its displacement stop point, please refer to the fourteenth figure, the buckle piece of the rubber connection piece (80) (82) The inner wall (721) of the respective slots (72) becomes the displacement stop point of the slide. Since the fixing plate and the sliding plate can no longer slide relative to each other, when the rubberized cotton is extruded by the present invention, although the rubberized cotton will be stored, the elastic force will not cause the fixing plate to slide. Then, as shown in the fifteenth " figure, the two splints (64) are completely close together, and the entire rubber (8 inches) is pressed by the two splints to completely extrude the moisture in the rubber. It should be noted that the displacement stop point of the slide plate (75) is not limited to the method of the fourteenth figure. Please refer to the seventh figure. A convex part (a) can be arranged on the bottom surface of each fixed plate (7〇) to make the slide plate.
