Example 4

Based on the novel bent rod and bent plate device in embodiment 1, as shown in fig. 1-4, the handle is: the slide block platform handle 1 and the acting force handle 2 are arranged in a front-back crossing manner and are mutually and rotatably connected. The front and back direction is the cross section direction of the rod to be bent. And one end of the sliding block platform handle 1 is provided with a bending sliding groove 5. First connecting hole 101 has been seted up at the lower extreme of the spout 5 that bends to slider platform handle 1 to set up effort handle through-hole on the bottom surface of the spout 5 that bends.

The pointed protrusion 10 may allow a user to position the slider platform handle 1 and the force handle 2 while grasping the pointed protrusion 10 to prevent slippage.

Example 7

Based on the novel bent rod and bent plate device in embodiment 1, as shown in fig. 9-12, the handle is: two acting force handles 2 which are arranged crosswise and are mutually connected in a rotating way.

The acting force connecting rod connecting hole 204 is rotatably connected with one end of the acting force connecting rod 12 through a rotating shaft.

The slider platform mechanism 3 is provided with a sliding groove through hole 304 and a handle connecting hole 302 in sequence from the threaded slider base sliding groove 301 to the acting force handle 2 along the axial direction of the acting force handle 2 towards one end of the acting force handle 2. The two acting force handles 2 are rotatably connected with each other on the sliding block platform mechanism 3 through a rotating shaft which sequentially penetrates through the 2 second connecting holes 202 and the handle connecting holes 302.

One end of the bending slide block 4, which is back to the slide block platform mechanism 3, is provided with a back plate 409 which is wider than the chute through hole 304. The back plate 409 is provided with a connecting shaft 408 protruding outwards, and the connecting shaft 408 is rotatably connected with the other end of the acting force connecting rod 12. The slide rail 402 of the bending slide block 4 is matched with the chute through hole 304, passes through the chute through hole 304, and is fixedly connected with the slide block fixing plate 43 through the fixing screw 44.

At this time, the slide rail 402 of the slider 4 is inserted into the chute through-hole 304 by bending and moves along the slide rail 402 and the chute through-hole 304. Therefore, the end of the force link 12 connected to the bending slider 4 can only drive the bending slider 4 to move closer to or away from the zigzag mechanism 205 along the chute through hole 304. When the two acting force handles 2 are far away from each other, the acting force connecting rod connecting holes 204 on the Z-shaped mechanism 205 are also far away from each other, and the ends of the two acting force connecting rods 12 connected with the Z-shaped mechanism 205 are driven to be far away from each other. The end of the acting force connecting rod 12 connected with the press bending sliding block 4 is limited by the movement of the press bending sliding block 4, and can only drive the end close to the zigzag mechanism 205, namely the end far away from the press bending base 6 to move. The slider fixing piece 43 and the back plate 409 prevent the slide rail 402 from falling out of the chute through hole 304. The rod bending operation can be realized by combining the rest operations in the embodiment 1. Since the movement stroke of the user operating the two acting force handles 2 is far beyond the movement stroke of the bending slide block 4, the user only needs to apply small force to realize the bending rod operation.

Example 10

Based on the novel bent rod and bent plate device in embodiment 7, as shown in fig. 16, a slide block replacing through hole 305 is additionally formed at one end of the chute through hole 304 close to the acting force handle 2.

This arrangement allows for an overall replacement operation of the press bending slider 4 in the bending rod apparatus described in example 7. The method specifically comprises the following steps: after the fixation between the press bending slider 4 and the acting force link 12 is released, the press bending slider 4 is moved to the slider replacement through hole 305, and then the press bending slider 4 to be replaced is taken out. A new press-bending slide 4 is then inserted from the slide exchange opening 305, with its slide rail 402 aligned with the chute opening 304. And finally, moving a new bending slide block 4 into the chute through hole 304, and reconnecting the bending slide block 4 and the acting force connecting rod 12 to complete the integral reloading operation of the bending slide block 4.
