The card is held so that each wheel 33 is restored to its free state. The abutting portion 5632 of the second brake member 56 that is slid upward by the brake abutting portion 5222 of the second operating lever 522 resets the rotating plate 563. When the pedaling force of the tread portion 5732 is released, the elastic member 574 is restored to deform and the rotating plate 573 of the second unlocking unit 57 is reset.

當操作人員位於該推車100的前端且需要制動該推車100時，腳踩該第一制動件53的踩踏板533，使該第一操作桿521旋轉而驅動連接桿526向前移動，連接桿526帶動該第二操作桿522旋轉。該第一、第二操作桿521、522兩端的旋轉桿5231帶動傳遞件36旋轉，而使每一傳遞件36的凸塊362滑動的抵持對應的滑動柱372，使每一滑動柱372的卡持部375卡入對應的卡齒部382內，以阻止萬向輪30旋轉。取消制動時，腳踩該第一解鎖組件55的踩踏部5551，該旋轉板555向上旋轉，該彈性件556發生彈性變形。該抵持部5552向上滑動地抵持該第一操作桿521上的抵持件552，使該第一操作桿521反方向旋轉而驅動連接桿526向後移動而復位，連接桿526帶動該第二操作桿522旋轉復位。該第一、第二操作桿521、522兩端的旋轉桿5231帶動傳遞件36復位，每一萬向輪30的彈性件373迫使對應的滑動柱372復位而脫離與卡齒部382的卡持，從而使每一輪子33恢復自由狀態。解除對該踩踏部5551的踩踏力，該彈性件556恢復形變而使該解鎖件553的旋轉板555復位。When the operator is located at the front end of the cart 100 and needs to brake the cart 100, the foot pedal 533 of the first brake member 53 is stepped on, the first operating lever 521 is rotated to drive the connecting rod 526 to move forward, and the connection is made. The rod 526 drives the second operating rod 522 to rotate. The rotating rods 5231 at the two ends of the first and second operating levers 521, 522 drive the transmitting member 36 to rotate, so that the projections 362 of each transmitting member 36 slide against the corresponding sliding posts 372, so that each sliding column 372 The catching portion 375 is snapped into the corresponding latching portion 382 to prevent the universal wheel 30 from rotating. When the brake is canceled, the tread portion 5551 of the first unlocking assembly 55 is stepped on, and the rotating plate 555 is rotated upward, and the elastic member 556 is elastically deformed. The abutting portion 5552 slidably abuts against the abutting member 552 of the first operating rod 521 to rotate the first operating rod 521 in the opposite direction to drive the connecting rod 526 to move backward and reset, and the connecting rod 526 drives the second portion. The operating lever 522 is rotated and reset. The rotating rods 5231 at the two ends of the first and second operating levers 521 and 522 drive the transmission member 36 to be reset, and the elastic member 373 of each of the universal wheels 30 forces the corresponding sliding column 372 to be reset to be disengaged from the engaging portion 382. Thereby each wheel 33 is restored to a free state. When the pedaling force of the stepping portion 5551 is released, the elastic member 556 is restored to deform and the rotating plate 555 of the unlocking member 553 is reset.

於其他的實施方式中，第一制動件53和第二制動件56可以採用相同的結構。In other embodiments, the first brake member 53 and the second brake member 56 may have the same structure.
