During this period, the suspension plate 21 can be displaced in the front-back direction through the transverse drive mechanism, and the suspension plate 21 can be moved up and down in the vertical direction through the longitudinal drive mechanism. The position of the suspension plate 21 can be adjusted in the left-right direction by cooperating with the screwing mechanism.

[0024] Specifically, the transverse drive mechanism includes an end head plate 3 fixedly connected to the end of the guide rod 2 away from the support plate 1. The inner surface of the end head plate 3 is rotatably connected with a lead screw 4. The lead screw 4 passes through the inner side of the displacement seat 6 and is threadedly engaged. The end of the lead screw 4 away from the support plate 1 is fixedly connected with a first knob 5.

[0025] Through the above technical scheme, when the first knob 5 is screwed, the lead screw 4 can be rotated. Under the relative limiting action of the guide rod 2, the displacement seat 6 can be driven by the lead screw 4 to move axially along the guide rod 2, i.e., the displacement seat 6 can be displaced in the front-back direction along the guide rod 2.

[0026] Specifically, the longitudinal drive mechanism includes a rotating rod 7 rotatably connected inside the displacement seat 6. The top of the rotating rod 7 is fixedly connected with a second knob 8. The outer surface of the rotating rod 7 is provided with a rotating groove 9.

[0027] Through the above technical scheme, the rotating groove 9 is provided on the rotating rod 7 and is at the same height as the guide clamping rod 10. This is to cooperate with the guide clamping rod 10 to limit the rotating rod 7, so as to avoid the longitudinal displacement of the rotating rod 7. Under the "lifting" action of the two groups of guide clamping rods 10, the rotating rod 7 can only rotate.

[0028] Specifically, the inner side of the displacement seat 6 is fixedly provided with guide clamping rods 10, and the number of the guide clamping rods 10 is two groups, both of which are in sliding connection with the rotating groove 9; the bottom of the rotating rod 7 is fixedly connected with a screw rod 11, and the outer surface of the screw rod 11 is in threaded connection with the inner surface of an inner screw cylinder 12.

[0029] Through the above technical scheme, the two groups of guide clamping rods 10 movably clamp the rotating rod 7 at the rotating groove 9, so that the rotating rod 7 drives the screw rod 11 to rotate synchronously in the self-rotation process, and then drives the inner screw cylinder 12 below to displace, during which the inner screw cylinder 12 rotates while moving longitudinally.

[0030] Specifically, the limiting mechanism includes a limiting groove 13 formed on the outer surface of the inner screw cylinder 12, one end of a connecting seat 14 is in threaded connection with a seat shaft 15, the end of the seat shaft 15 away from the connecting seat 14 is fixedly connected with a third knob 16, and the end of the seat shaft 15 away from the third knob 16 is rotatably connected with an inner arc clamping block 17.

[0033] Through the above technical scheme, the through hole 22 and the strip-shaped hole 23 are in communication, after the cross rod 18 and the rubber sleeve 19 pass through the through hole 22, when the screw 24 is screwed, the strip-shaped hole 23 of the memory metal plate 20 will gradually shrink, that is, the diameter of the through hole 22 decreases, until the memory metal plate 20 tightly wraps the rubber sleeve 19, so that the cross rod 18 together with the rubber sleeve 19 are in a stable state.

[0034] Working principle: in the use process of the suspension device, first make the suspension plate 21 and the support plate 1 in indirect stable connection state, that is, make the two groups of inner screw cylinders 12 respectively inserted into the corresponding connecting seats 14, then rotate the third knob 16 to drive the seat shaft 15 to rotate, the seat shaft 15 gradually penetrates into the connecting seat 14 in the rotating process, and because the connecting seat 14 plays a relative limiting role on the inner arc clamping block 17, and the seat shaft 15 is rotationally connected with the inner arc clamping block 17, therefore, in the self-rotation process of the seat shaft 15, the inner arc clamping block 17 does not synchronously self-rotate, but synchronously penetrates into the connecting seat 14 with the seat shaft 15, until the arc surface of the inner arc clamping block 17 tightly clamps the limiting groove 13 on the outer surface of the inner screw cylinder 12, that is, the suspension plate 21 is indirectly and stably installed on the support plate 1, in the use process of the suspension device, the position of the suspension device (suspension plate 21) can be adjusted from multiple directions, first, the first knob 5 can be rotated to drive the screw rod 4 to rotate, thereby driving the displacement seat 6 to slide along the guide rod 2 in the front and back directions, that is, the lower suspension plate 21 is adjusted in position in the front and back directions, and when the second knob 8 is rotated, the rotating rod 7 can be self-rotated, and during the rotation, the rotating rod 7 is supported by the guide clamping rod 10 in the rotation groove 9, so that the rotating rod 7 only self-rotates, but does not deviate in other directions, in this process, the screw rod 11 synchronously self-rotates, and the self-rotation of the screw rod 11 drives the inner screw cylinder 12 to move, so that the inner screw cylinder 12 moves longitudinally while self-rotating, and the connecting seat 14 at the bottom of the inner screw cylinder 12 also synchronously moves in the up and down directions, thereby moving the lower suspension plate 21 in the vertical direction, finally, the memory metal plate 20 can be slid along the surface of the rubber sleeve 19, so that the suspension plate 21 at the bottom of the memory metal plate 20 moves in the left and right directions, after the suspension plate 21 moves horizontally to the corresponding position, the fastening screw 24 can be tightened, the screw 24 gradually penetrates into the memory metal plate 20, the strip-shaped hole 23 and the through hole 22 are gradually contracted, until the memory metal plate 20 tightly wraps the rubber sleeve 19 at the through hole 22, so that the memory metal plate 20 is stably arranged on the rubber sleeve 19 on the surface of the cross rod 18 (the rubber sleeve 19 can improve the wrapping stability of the memory metal plate 20), that is, the suspension plate 21 after moving horizontally to the corresponding position is in a stable state, at this time, when the suspension device faces the workpiece with irregular shape or large size, the installation position of the suspension plate 21 can be flexibly adjusted from different directions (front and back, left and right, up and down) according to the needs, thereby effectively improving the flexibility, adaptability and welding quality of the suspension device.
