[0049] Installation: 1, push the left half shell 1 and the right half shell 2 into the base, connect with screws; 2, insert the fixed rod of the tray into the corresponding top fixed hole of the left half shell and the right half shell, that is, the installation is completed.

[0050] Example 2:

[0051] As Figures 22-24 shown, it is basically the same as example 1, the difference is that the front and rear moving drive assembly in this embodiment 1 also includes a fourth pulley 59, a second belt 60, a fifth pulley 61; the rotating shaft of the third pulley 34 also has a fourth pulley 59 installed, the right end of the rotating shaft of the left hand wheel 25 also has a fifth pulley 61 installed, the second belt 60 is sleeved on the fourth pulley 59 and the fifth pulley 61; the tensioner bracket 39 is an up-down moving type tensioner bracket.

[0052] The up-down moving type tensioner bracket can adopt various existing up-down moving structures, for example: the up-down moving type tensioner bracket includes a guide pipe, a lifting block, a cam, a rotating shaft, a tensioner bracket lifting handle 58, the tensioner is installed on the upper end of the lifting block, the lower end of the lifting block passes through the guide pipe, the guide pipe is fixed on the base by the connecting bracket, the cam is below the lower end of the lifting block, the cam is fixed on one end of the rotating shaft, the other end of the rotating shaft is fixed with the tensioner bracket lifting handle 58, the rotating shaft is installed on the bearing seat through the bearing, and the bearing seat is fixed on the base. Rotate the rotating shaft to make the cam rotate and make the lifting block move up and down.

[0053] Description: example 1 front and rear moving drive assembly adopts a first belt 28, this embodiment 2 adopts two belts to realize the corresponding function.

[0054] When the power is off, the up-down moving type tensioner bracket descends, the tensioner leaves the first belt 28, and the first belt 28 is loosened. Hold the left hand wheel handle 24 and rotate the left hand wheel 25, the left hand wheel 25 rotates to drive the fifth pulley 61 to rotate, which drives the first gear 36 to rotate through the first belt 28, and then drives the main gear to rotate through the second gear, the third gear and the steel wire flexible shaft, the main gear 45 rotates to drive the pinion 54 to rotate, the pinion 54 and the front and rear moving screw constitute a screw pair, the front and rear moving screw drives the sliding cylinder 49 to slide along the outer cylinder 47 in the front and rear direction, so as to drive the chuck 22 to move forward and backward, at the same time, hold the right hand wheel handle 16 to drive the shaft to rotate, the shaft drives the crank to rotate, the crank drives the up-down moving seat 48 to move up and down (the up-down moving seat moves up and down along the support 27), so as to drive the movement of the core 42 and the chuck 22, so as to realize the manual slicing in the power-off state; That is, manual driving.

[0055] Example 3:

[0056] Further, the up-and-down moving mechanism can also be electric / hand, that is, a belt pulley (i.e., the sixth belt pulley) is additionally arranged at the left end of the shaft of the right hand wheel 32, a second motor is installed on the base 18, a seventh belt pulley is installed on the output shaft of the second motor, and the third belt is sleeved on the sixth belt pulley and the seventh belt pulley, so that the electric up-and-down movement can be realized.
