Referring to fig. 5, the driving roller 31 and the driven roller 32 are covered with a belt 33. Specifically, the conveyor belt 33 is formed by splicing a plurality of base plates 331, and two adjacent base plates 331 are connected by hinges to form a closed endless conveyor belt 33 in a surrounding manner. Preferably, the base plate 331 is rectangular parallelepiped, and the long side of the base plate 331 is a hinged side. When one of the substrates 331 of the conveyor belt 33 is damaged, only the damaged substrate 331 thereof needs to be replaced, thereby extending the life span of the conveyor belt 33 and reducing the cost of repair and maintenance.

Further, a baffle plate 332 is rotatably provided on the base plate 331, and the baffle plate 332 is provided in a rectangular parallelepiped shape. The length direction of the baffle 332 is the same as the length direction of the substrate 331, and the length and width of the baffle 332 are smaller than those of the substrate 331. The rotation axis of the baffle 332 is located at one end of the baffle 332 in the longitudinal direction and is parallel to the axis of the driving roller 31. The baffle 332 is rotated to make the baffle 332 parallel or form an angle with the base 331. When the baffle 332 and the base 331 are parallel to each other, the baffle 332 is in a retracted state, so that the upper end surface of the handrail 2 is flat to facilitate holding the handrail 2. When the baffle 332 and the base 331 are perpendicular to each other, the baffle 332 can abut against a side of the weight near the driving roller 31, thereby blocking the weight placed on the conveyor belt 33 from sliding downward due to gravity, so that the conveyor belt 33 is more stable for the transportation of the weight.

An end surface of the base plate 331 is provided with an insertion groove 3311 into which the baffle plate 332 is inserted. The cross section of the insert slot 3311 is rectangular to fit the baffle plate 332.

The depth of the hand-touch groove 3312 is greater than the depth of the engagement groove 3311, and the side of the hand-touch groove 3312 near the rotation axis of the baffle plate 332 extends into the engagement groove 3311. When it is necessary to open the blocking plate 332, the user puts his hand into the hand contact groove 3312 to abut against the lower end surface of the blocking plate 332, thereby rotating the blocking plate 332.

Further, a limit groove 3313 is formed in the insertion groove 3311. The position-limiting groove 3313 is located on a side of the insertion groove 3311 away from the hand-touch groove 3312. The end surface of the baffle 332 facing away from the insertion groove 3311 is provided with a position-limiting step 3321 fitted into the position-limiting groove 3313. The position-limiting step 3321 is fitted into the position-limiting groove 3313 to restrict the rotation of the baffle plate 332, thereby making the placement of the weight on the base plate 331 more stable.

Referring to fig. 2 and 4, a driving mechanism 34 for driving the driving roller 31 to rotate in one direction is installed on the handrail 2 so that the conveyor belt 33 can move the heavy object from the driving roller 31 in the direction of the driven roller 32. Specifically, the driving mechanism 34 includes a ratchet wheel 341 coaxially and fixedly disposed on the driving roller 31, a pawl 342 for cooperating with the ratchet wheel 341, and an elastic member 343 for urging the pawl 342 to return, and the pawl 342 and the elastic member 343 are both mounted on the handrail 2. The driving roller 31 is provided with a handle 346 for driving the driving roller 31 to rotate. Preferably, the elastic member 343 is a compression spring, a torsion spring, or a coil spring. The ratchet wheel 341 cooperates with the pawl 342 to restrict the rotational direction of the ratchet wheel 341, thereby achieving restriction of the rotational direction of the ratchet wheel 341, and thus achieving restriction of the rotational direction of the driving roller 31, thereby achieving unidirectional movement of the conveyor belt 33.

Preferably, the handle 346 includes a shaft portion 3461 coaxially and fixedly connected with the driving roller 31 and a handle portion 3462 hingedly connected to the shaft portion 3461, the rotation axis of the handle portion 3462 is perpendicular to the axis of the shaft portion 3461 so that the axis of the handle portion 3462 can be perpendicular to or parallel to the axis of the shaft portion 3461, a handle sleeve is sleeved on the handle portion 3462, and the handle sleeve is rotatably connected with the handle portion 3462.

Further, a slider 344 is slidably provided on the handrail 2, and the slider 344 moves in a direction approaching or departing from the driving roller 31. The pawl 342 is hingedly connected to a glide block 344. One end of the elastic member 343 is fixedly connected to the pawl 342, and the other end of the elastic member 343 is fixedly connected to the slider 344.

A guide rod 345 is slidably provided on the handrail 2. The guide rod 345 moves in the same direction as the belt 33. One end of the guide rod 345 is close to the driving roller 31 and fixedly connected with the sliding block 344, and the other end of the guide rod 345 is located at one end of the conveyor belt 33 far away from the driving roller 31. Preferably, the guide rod 345 has a length equal to a linear distance between the driving roller 31 and the driven roller 32.
