The first U-shaped support 31 has first and second through holes 311, 312. The first and second through holes 311, 312 are disposed on two sides of the bottom of the first U-shaped support 31, respectively. The first U-shaped support 31 is provided with a first spindle 41 and a second spindle 42. The first and second spindles 41, 42 each have one end provided with a first stop portion 411 and a second stop portion 421, respectively. The first spindle 41 has a first rod segment 412 which penetrates the first through hole 311, such that a first flat bar 413 disposed at the other end of the first spindle 41 is inserted into and fixed to a first lower eccentric hole 511 of a first eccentric block 51. A fifth flat bar 611 disposed at one end of a first independent shaft 61 oriented longitudinally is inserted into and fixed to a first upper eccentric hole 512 of the first eccentric block 51. The first independent shaft 61 is flanked and supported by two second bearings 612. The first independent shaft 61 is intermediately and fixedly provided with a second gear 613. The second gear 613 meshes with the second worm gear 22. The second spindle 42 has a second rod segment 422 which penetrates the second through hole 312, such that a second flat bar 423 disposed at the other end of the second spindle 42 is inserted into and fixed to a second lower eccentric hole 521 of a second eccentric block 52. A seventh flat bar 621 disposed at one end of a second independent shaft 62 oriented longitudinally is inserted into and fixed to a second upper eccentric hole 522 of the second eccentric block 52. The second independent shaft 62 is flanked and supported by two third bearings 622. The second independent shaft 62 is intermediately and fixedly provided with a third gear 623.
