The sliding rail 132 is fixed on the carrying unit 120, and the sliding block 134 is opposite to the limiting sliding mechanism. The member 120 is fixed, and the carrying unit 200 is slidably disposed on the limiting member 120 through the limiting sliding mechanism 130. With this configuration, the freedom of movement and the freedom of rotation of the carrying unit 200 in the front, rear, left, and right directions are restricted by the stopper 120, and can only move along the base 100 and the stopper 120. The method of the base 100 slides up and down.

The following will describe how the actuating unit 400 drives the clamping member 310 to expand or fold relative to the object 2 to clamp the object 2. Please refer to FIGS. 6 and 7, where FIG. 6 is the base and the first clamping in FIG. 3 The exploded schematic diagram of the object, the second clamping piece and the actuating unit, and FIG. 7 is a three-dimensional schematic diagram of the object in FIG. 1. As shown in FIG. 6, the first actuating member 410a and the second actuating member 410b each include a latching portion 414, and the first clamping member 310a and the second clamping member 310b each include a rotating portion 312, wherein The detent portion 414 is, for example, a rack, and the rotating portion 312 is, for example, a bearing gear or a worm, and each detent portion 414 is latched on the rotating portion 312 by means of tooth meshing. When the first actuating member 410a and the second actuating member 410b slide relative to the base 100 toward the outer sides of the base 100, the rotating parts 312 are driven by the teeth of the latching portion 414 and are relative to the latching portion 414. The surface of the rotation of the first clamping member 310a and the second clamping member 310b rotate counterclockwise and clockwise in FIG. 4, so as to retract relative to the object 2 and clamp the object 2 from the left and right sides.

Similarly, when the first actuating member 410a and the second actuating member 410b respectively slide in the direction of the center of the base 100 relative to the base 100, each rotating portion 312 is driven by the teeth of the latching portion 414 and is relative to the latching portion. The surface of 414 rotates, and the first clamping member 310a and the second clamping member 310b rotate in the clockwise and counterclockwise directions in FIG. 4, so as to expand relative to the object 2 and stop clamping the object 2.

In addition, in order to ensure that the object 2 can be clamped by the clamping unit 300 and accurately aligned, preferably, a holding member 314 is provided on the first holding member 310a, and a holding member 314 is provided on the second holding member 310b. The positioning member 316, wherein the rigidity of the holding member 314 is less than the rigidity of the first holding member 310a. In this embodiment, the material of the first holding member 310a is, for example, metal, and the holding member 314 is made of, for example, rubber or plastic, and holds The member 314 protrudes relative to the first clamping member 310a, and the positioning member 316 is, for example, a roller. On the other hand, as shown in FIG. 7, the object 2 is formed with a positioning portion 21 on one side corresponding to the positioning member 316. In this embodiment, the positioning portion 21 is, for example, a groove, but may also be other corresponding positioning members 316. The geometric characteristics of the shape. When the first clamping member 310a and the second clamping member 310b are folded relative to the object 2, the positioning member 316 will abut against the positioning portion 21, and the clamping unit 300 abuts against the other of the object 2 through the holding member 314 side. In other words, one side of the object 2 is held by the holding member 314, and the positioning portion 21 on the other side is guided by the positioning member 316 during the folding process of the holding member 310 and moves to the correct position, so that it can ensure The object 2 is indeed clamped by the clamping unit 300 and accurately aligned to avoid friction between the two sides of the object 2 and the frame 1, and since the rigidity of the holding member 314 is less than the rigidity of the first clamping member 310a, the object 2 can be prevented. The collision is damaged due to the clamping of the clamping unit 300.

It is worth mentioning that, since the position of the positioning portion 21 of different objects 2 may vary with the thickness and size of the object 2, for this reason, the second clamping member 310b is preferably further equipped with a positioning sliding mechanism 320. The positioning sliding mechanism 320 includes a sliding rail 322 and a sliding block 324, wherein the sliding rail 322 is fixed on the second clamping member 310b, the sliding block 324 is fixed relative to the positioning member 316, and the positioning member 316 passes through the positioning sliding mechanism 320 It is slidably disposed on the second clamping member 310b. With this configuration, the carrying mechanism 3 can adjust the relative distance between the positioning member 316 and the second clamping member 310b through the positioning sliding mechanism 320 according to the size and shape of different objects 2 to satisfy the position of the positioning portion 21 of each object 2.

Please refer to FIG. 8, which is a schematic cross-sectional view of FIG. 3 along the X-X section. In the above, although the first actuating member 410a drives the carrying unit 200 to rise, it is described separately from the first actuating member 410a and the second actuating member 410b driving the first clamping member 310a and the second clamping member 310b. However, the two can be synchronized movements during actual operation. Specifically, when the object 2 slides down onto the frame 1 along the shelf of the storage area of FIG. 1, the carrying mechanism 3 can drive the first actuating member 410a and the second actuating member 410b through the cylinder 510 of the power unit 500 at the same time. Sliding toward both sides of the base 100, the abutting portion 210 of the bearing unit 200 will be pressed by the actuating portion 412 to drive the bearing unit 200 to slide upward, thereby lifting the object 2 upward and away from the surface of the frame 1.
