[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of the utility model lie in that:

[0016] When using this mechanism, the operator can hold the pressure bar in advance and use the first rotating rod to press down the bar body in conjunction with the sleeve and connecting frame. During this process, the pressure block, which is movably connected to the sleeve via the second rotating rod, can be inserted into the groove above the limiting guide block, and press down along with the pressure adjustment mechanism installed below. This adapts to lithography work of different heights. When the pressure bar is pressed to the specified angle, the operator can use the third rotating rod to rotate the pressure bar to one side of the telescopic sub-rod. Then, the end of the pressure bar is inserted into the flexible plastic retaining ring inside the fixed support frame to form a limit. At this time, the adjustment component in the pressure adjustment mechanism is used to adjust the pressure of the pressure plate on the lithography plate to complete the subsequent printing work. After the operation is completed, the operator can separate the pressure rod from the flexible plastic retaining ring. At this time, the pressure rod, under the reset of the telescopic main rod, telescopic secondary rod, and return spring, forms an initial state with the connecting frame. Subsequently, the first torsion spring located around one end of the fourth rotating rod inside the frame presses against the connecting sleeve rod in the indefinite state of the pressure rod. Since there is a guide rod abutting above one end of the connecting sleeve rod, the guide rod can perform upward lifting operation along the slot between the second and third irregular frames. This can lift the pressure plate to a certain angle. When a certain angle is reached, the corresponding second torsion springs located around the fixed rods on both sides inside the frame can simultaneously lift the two side blocks of the lower connecting frame, thereby achieving the effect of natural reset of the pressure rod. It is portable and practical.

[0017] After the limiting guide block descends to a certain height, the pressure regulating mechanism of this utility model allows the operator to manually crank the hand-cranked threaded disc, a component of the pressure regulating mechanism. Under the action of the threaded screw in the middle, the hand-cranked threaded disc can be displaced by the thread. Since there is a movable rotating block between the lower fixed block fixed below the hand-cranked threaded disc and the pressure plate, the hand-cranked threaded disc can indirectly carry the pressure plate and cooperate with the guide frame to carry out stable downward pressing operations, thereby adjusting the pressure of the stone slab during the pressing operation.

[0026] The portable reset mechanism 13 comprises an adjusting assembly 131, which is installed at the joint of the connecting frame 7 and the pressing rod 8. The adjusting assembly 131 comprises a third rotating rod 1311, which is installed at the middle part of the connecting frame 7. A limiting block 1312 is fixed at one side of the inner part of the connecting frame 7, and an extension female rod 1313 is installed at the other side of the inner part of the connecting frame 7. The extension female rod 1313 movably has an extension male rod 1314 at the middle part. A side block 1315 is fixed at the periphery of the proximal end of the extension male rod 1314. A reset spring 1316 is connected to the inner side of the side block 1315. An activity block 1317 is installed at the end of the extension male rod 1314. The third rotating rod 1311 is movably connected to one end of the pressing rod 8. A reset assembly 132 is installed at one side of the inner part of the rack 1.

Second torsion springs 137 are installed at the periphery of the two fixed rods 136. The reset assembly 132 comprises a fourth rotating rod 1321, which is installed at one side of the inner part of the rack 1. A connecting sleeve rod 1322 is sleeved at the periphery of one side of the fourth rotating rod 1321. A first torsion spring 1323 is installed at the periphery of one end of the fourth rotating rod 1321. A guide rod 1324 is abutted at one end of the upper part of the connecting sleeve rod 1322. The guide rod 1324 is movably connected to the space between the second special-shaped frame 3 and the third special-shaped frame 4. When the mechanism is used, the personnel can hold the pressing rod 8 to cooperate with the sleeve frame 6 and the connecting frame 7 to rotate the first rotating rod 5 to press the rod body. In this process, the pressing block 10 movably connected to the sleeve frame 6 through the second rotating rod 9 can be clamped into the groove above the limiting guide block 11 and press the pressure adjusting mechanism 12 below to adapt to the stone plate work of different heights. When the pressing rod 8 is pressed to the specified angle, the personnel can hold the pressing rod 8 to rotate the third rotating rod 1311 to offset to one side of the extension male rod 1314, and then hold the pressing rod 8 to clamp into the flexible plastic clasp 134 on the inner side of the fixed support frame 133 to limit. At this time, the pressure adjusting mechanism 12 is used to adjust the pressure of the pressing plate 126 on the stone plate to complete the subsequent print work. After the work is completed, the personnel can separate the pressing rod 8 from the flexible plastic clasp 134. At this moment, the pressing rod 8 is reset to the initial state with the connecting frame 7 under the reset of the extension female rod 1313, the extension male rod 1314 and the reset spring 1316. After that, the first torsion spring 1323 at the periphery of one end of the fourth rotating rod 1321 is abutted to the connecting sleeve rod 1322 under the non-limiting state of the pressing rod 8. Since the guide rod 1324 is abutted at one end of the upper part of the connecting sleeve rod 1322, the guide rod 1324 can be lifted to a certain angle along the space between the second special-shaped frame 3 and the third special-shaped frame 4.When reaching a certain angle, the corresponding second torsion spring 137 arranged around the fixed rod 136 on both sides of the inside of the frame 1 can simultaneously lift the blocks on both sides of the lower connecting frame 121, so that the natural reset effect of the pressing rod 8 can be achieved.

[0027] Working principle: when using the mechanism, personnel can pre-hold the pressing rod 8 to cooperate with the sleeve frame 6, the connecting frame 7, and use the first rotating rod 5 to rotate and press the rod body. During this process, the pressing block 10 movably connected with the sleeve frame 6 through the second rotating rod 9 can be clamped into the groove arranged above the limiting guide block 11 and pressed downward with the pressure adjusting mechanism 12 arranged below, so as to adapt to the stone plate work of different heights. When the pressing rod 8 is pressed to a specified angle, the personnel can hold the pressing rod 8 and use the third rotating rod 1311 to rotate to one side of the telescopic sub-rod 1314, and then hold the pressing rod 8 and clamp it into the flexible plastic snap ring 134 arranged inside the fixed support frame 133 to form a limit. At this time, the adjusting assembly in the pressure adjusting mechanism 12 is used to adjust the pressure of the pressing plate 126 on the stone plate, and then the subsequent printmaking work is completed. When the work is completed, the personnel can separate the pressing rod 8 from the flexible plastic snap ring 134. At this time, the pressing rod 8 is reset with the connecting frame 7 under the reset of the telescopic mother rod 1313, the telescopic sub-rod 1314 and the reset spring 1316. After that, the first torsion spring 1323 arranged around one end of the fourth rotating rod 1321 in the inside of the frame 1 is pressed against the connecting sleeve rod 1322 under the non-limited state of the pressing rod 8. Since the abutting rod 1324 is arranged above one end of the connecting sleeve rod 1322, the abutting rod 1324 can be lifted up along the air slot between the second special-shaped frame 3 and the third special-shaped frame 4, so that the pressing plate 126 can be lifted up to a certain angle. When reaching a certain angle, the corresponding second torsion spring 137 arranged around the fixed rod 136 on both sides of the inside of the frame 1 can simultaneously lift the blocks on both sides of the lower connecting frame 121, so that the natural reset effect of the pressing rod 8 can be achieved.
