Referring to fig. 3 and 4, the present embodiment is different from embodiment 1 mainly in that, in the present embodiment, the present embodiment further includes a pressing mechanism 7, the pressing mechanism 7 includes a fixing rod 71, a clip plate 72, a third spring 73, a rack 74, a gear 75 and a pressing plate 76, the fixing rod 71 is fixedly connected to four corners of the top of the frame 1, the clip plate 72 is slidably disposed between the four fixing rods 71, the clip plate 72 is sleeved outside the transparent cover plate 2, the third spring 73 is connected between the bottom of the clip plate 72 and the top of the frame 1, the third spring 73 is sleeved on the fixing rod 71, the rack 74 is fixedly connected to both sides of the front and rear sides of the clip plate 72, the gear 75 is rotatably mounted to both sides of the front and rear sides of the transparent cover plate 2, the gear 75 is engaged with the rack 74, a pressing plate 76 capable of pressing the original and the drawing manuscript is mounted between the front and right and left side gears 75, the pressing plate 76 capable of pressing the, the platen 76 is located within the light transmissive cover 2.

Firstly, an operator pushes the return plate 72 to move downwards, the third spring 73 is compressed, the return plate 72 moves downwards to drive the rack 74 to move downwards, the rack 74 moves downwards to drive the gear 75 to rotate outwards, the gear 75 rotates outwards to drive the pressing plate 76 to swing upwards, when the pressing plate 76 swings upwards to a proper position, the return plate 72 stops being pushed, an original and a drawing manuscript can be placed on the light-transmitting cover plate 2 and moves to the position below the pressing plate 76, the return plate 72 is released, and due to the action of the third spring 73, the return plate 72 moves upwards to drive the rack 74 to move upwards, further the pressing plate 76 is driven to swing downwards to press and fix the original and the drawing manuscript, and the next operation can be started. Similarly, when copying is completed, the original and the drawing manuscript are released by the pressing plate 76 and then taken out by the above operation. Therefore, the copying effect can be prevented from being influenced by the movement of the original manuscript and the drawing manuscript.

Example 3

Referring to fig. 2, 3 and 6, the present embodiment is different from embodiment 1 and embodiment 2 mainly in that the present embodiment further includes a swing rod 8, a stop lever 9 and a torsion spring 10, the swing rod 8 is hinged to the left side of the bottom of the front and rear hollow rods 51, the swing rod 8 is hinged to the rear side of the bottom of the left and right hollow rods 51, the torsion spring 10 is disposed at the hinge position of the swing rod 8 and the hollow rods 51, the stop lever 9 is fixedly connected to the right end of the front and rear swing rods 8, the stop lever 9 is fixedly connected to the front end of the left and right swing rods 8, and the stop lever 9 contacts with and cooperates with the shift lever 62.

The folding type folding frame is characterized by further comprising a movable plate 12, a fourth spring 13 and clamping rods 15, guide plate grooves 11 are formed in the front side and the rear side of the left and right side handles 68, the movable plate 12 is arranged between the guide plate grooves 11 in the front side and the rear side in a sliding mode, the fourth spring 13 is connected between the outer side face of the movable plate 12 and the outer side face of the guide plate grooves 11, the clamping rods 15 are fixedly connected to the front side and the rear side of the lower portion of the inner side face of the movable plate 12, clamping holes 14 matched with the clamping rods 15 are formed in the front side and the rear side of the left side face and the front side.

When the shifting lever 62 needs to be pulled to move outwards, the outer end of the swing rod 8 can be pushed to swing inwards, the outer end of the swing rod 8 swings inwards to enable the inner end to swing downwards, the torsion spring 10 stretches, the inner end of the swing rod 8 swings downwards to drive the stop lever 9 to swing downwards, the stop lever 9 swings downwards to be separated from the shifting lever 62, and then the shifting lever 62 can be pulled to move outwards. When the shift lever 62 does not need to move, the swing rod 8 can be released, and due to the action of the torsion spring 10, the inner end of the swing rod 8 swings upwards to drive the stop lever 9 to swing upwards for resetting, so that the shift lever 62 is stopped. Thus, the situation that the chute rod 61 moves due to the fact that an operator touches the shift lever 62 by mistake can be avoided.

After the copying is completed, the movable plate 12 can be pulled to move outwards, the fourth spring 13 is compressed, the movable plate 12 moves outwards to drive the clamping rod 15 to move outwards, the clamping rod 15 moves outwards to be separated from the clamping hole 14, the movable plate 12 stops being pulled, the handle 68 can be pulled to move downwards to drive the profiling block 63 to move downwards, and the tooth block 64 is also separated from the movable clamping block 66. When the hollow rods 51 are reset and the handle 68 is reset, the movable plate 12 is released, and due to the action of the fourth spring 13, the movable plate 12 moves rightwards to drive the clamping rod 15 to move rightwards to be inserted into the clamping hole 14 to fix the handle 68. Therefore, the situation that the tooth block 64 is separated from the movable clamping block 66 due to the fact that an operator accidentally touches the handle 68 can be avoided.
