The second guide wheels 232 are disposed on one side of the movable plate 21 away from the connecting plate 11, in this embodiment, the second guide wheels 232 are plural, and the plural second guide wheels 232 are respectively abutted against two opposite sidewalls of the sliding plate 231, so that the sliding plate 231 can more stably perform a linear lifting movement. The guiding groove 233 is opened in the sliding plate 231, and the guiding groove 233 penetrates the sliding plate 231. The guide wheel 234 is positioned in the guide groove 233, and the guide wheel 234 is capable of sliding along the length direction of the guide groove 233 such that the guide wheel 234 moves relative to the sliding plate 231. The connecting rod 235 is rotatably connected to the side of the guide wheel 234 facing the connecting plate 11, and one end of the connecting rod 235 remote from the guide wheel 234 passes through the movable plate 21 and is then connected to the connecting plate 11. When the matching distance between the two panels needs to be adjusted to be the distance of the first stroke, the sliding plate 231 is driven to linearly descend, so that the guide wheels 234 move along the length direction of the guide grooves 233, and the movement of the guide wheels 234 drives the connecting rods 235 to synchronously move, so that the connecting plates 11 move to the distance of the first stroke along the direction close to the second opening and closing assembly 3, and the assembly requirement of the wire harness is met.
Specifically, the guide groove 233 includes a first guide portion 2331, a second guide portion 2332, and a third guide portion 2333, the first guide portion 2331 and the second guide portion 2332 are all disposed vertically, the first guide portion 2331 and the second guide portion 2332 are disposed at intervals along the moving direction of the sliding plate 231, and the first guide portion 2331 is located below the second guide portion 2332.

In contrast, when the matching distance between the two blocks is reduced from zero by the distance of the first stroke, the sliding plate 231 is driven to linearly descend, so that the guide wheels 234 sequentially move from the second guide portion 2332 to the third guide portion 2333 and then move to the first guide portion 2331, and the movement of the guide wheels 234 drives the connecting rod 235 to synchronously move, so that the connecting plate 11 moves to a distance for driving the blocks to move by the first stroke along a direction away from the second opening and closing assembly 3, and the matching distance between the two blocks is zero.
Referring to fig. 3 and 4, fig. 4 is a perspective view of fig. 3 with the slip plate 231 removed.

Referring to fig. 1 and 3, the driving unit 24 includes a fixing frame 241, a driving member 242 and a pushing plate 243, the fixing frame 241 is connected to the bottom side of the movable plate 21, the driving member 242 is disposed on the fixing frame 241, one side of the pushing plate 243 is connected to the driving end of the driving member 242, and one side of the pushing plate 243 facing away from the driving member 242 is connected to the sliding plate 231. In this embodiment, the driving member 242 is an electric cylinder, and an output end of the electric cylinder is connected to a side of the pushing plate 243 away from the sliding plate 231. When the matching distance between the two blocks is increased from zero to a distance of a first stroke, the driving piece 242 drives the sliding plate 231 to linearly ascend, so that the guiding wheels 234 sequentially move from the first guiding part 2331 to the third guiding part 2333 and then move to the second guiding part 2332, and the movement of the guiding wheels 234 drives the connecting rod 235 to synchronously move, so that the connecting plate 11 moves to a distance for driving the drawing plate to move by the first stroke along a direction approaching to the second opening and closing assembly 3.
The structure of the second opening and closing assembly 3 is the same as that of the first opening and closing assembly 2, and therefore, a detailed description is omitted here. When the matching distance between two blocks is required to be increased from zero to a distance of a second stroke, the sliding plate 231 in the second opening and closing assembly 3 is driven to linearly rise, so that the corresponding guide wheels 234 sequentially move from the first guide part 2331 to the third guide part 2333 and then move to the second guide part 2332, the movement of the guide wheels 234 drives the connecting rod 235 to synchronously move, and the connecting plate 11 moves to a distance for driving the drawing plate to move a second stroke along a direction approaching to the second opening and closing assembly 3. Of course, when the matching distance between the two blocks needs to be adjusted to be the sum of the first stroke and the second stroke, the first opening and closing assembly 2 drives the drawing board to move by the first stroke, and then the second opening and closing assembly 3 indirectly drives the drawing board to move by the second stroke. During practical application, the assembly requirement of the wire harness is adjusted.
In summary, in the multi-position drawing board opening and closing mechanism of the present utility model, when the matching distance between two drawing boards needs to be increased to assemble different types of wire harnesses, the driving piece 242 drives the sliding board 231 to linearly rise, so that the guiding wheel 234 sequentially moves from the first guiding portion 2331 to the third guiding portion 2333 and then moves to the second guiding portion 2332, and the movement of the guiding wheel 234 drives the connecting rod 235 to synchronously move, so that the connecting plate 11 moves to a distance for driving the drawing board to move by a first stroke along a direction approaching to the second opening and closing component 3.
