The positioning rod cannot be separated from the movable seat 35 through the matching of the connecting rod 65 and the limiting hole 64, and can rotate relative to the movable seat 35, the reset spring 38 of the present application has two functions, the first function is to make the movable seat 35 have a movement trend moving to the side far away from the positioning seat 36, and the movement trend is transmitted to the movable seat 35 by applying acting force to the positioning part 37; the second effect is to make the setting element 37 have the tendency of rotating to the initial work position and returning, because the bottom of connecting rod 65 is plane 66, and upper portion is arcwall face 67, and setting element 37 is when initial work position, and plane 66 supports with movable seat 35 and leans on, so when connecting rod 65 caused its relative spacing hole 64 to rotate because of the effect of slider 40, through the effort of reset spring 38 to arcwall face 67, can make setting element 37 have the tendency of rotating to the initial work position and returning, when slider 40 did not receive external force promptly, can make setting element 37 rotate.

As shown in fig. 11, in the present embodiment, the movable seat 35 has a spring installation groove 68, the limiting hole 64 is communicated with the arc installation groove, the connecting rod 65 is located at the bottom of the installation groove, and the return spring 38 is sleeved in the spring installation groove 68. By providing the spring mounting slots 68, reliable operation of the spring is facilitated.

As shown in fig. 13, in the present embodiment, the positioning seat 36 has a mounting post 69, and the mounting post 69 is inserted into one end of the return spring 38; the slider 40 is a cylindrical slider 40.

As shown in fig. 8, in the present embodiment, the casing 1 has a T-shaped groove 70 therein, and the positioning seat 36 has a T-shaped portion 71 matching with the T-shaped groove 70. By providing the T-shaped slot 70 and the T-shaped portion 71, quick and reliable installation of the positioning seat 36 can be facilitated.

As shown in fig. 14, when the control lever 6 is pressed, the control lever 6 moves the pull rod 29, and the suction cup 4 moves toward the stopper groove 23 to be deformed.

The brick paving machine has the advantages that the vibration mechanism is long in service life, high in reliability and strong in vibration effect, the brick suction mechanism omits a spring, the structure is simpler, the control rod 6 positioning mechanism can enable the sucker 4 to be kept in a brick suction state, and the use is more labor-saving.

The above only is the preferred embodiment of the present invention, not therefore the limit the patent protection scope of the present invention, all applications the equivalent structure transformation made by the contents of the specification and the drawings of the present invention is directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
