Figure 6 is a schematic diagram of the second guide plate being assembled on the first guide plate in some embodiments of the present invention, showing the position of the guide post at the stopper. As shown in Figure 5, in some embodiments, the two groove walls (142, 142') respectively have a first section 145 and a second section 146, and the first section 145 is adjacent to the second section 146. At the opening 143, and a thickness D2 of the first section 145 is less than a thickness D3 of the second section 146, the thickness D2 of the first section 145 is less than the width of the neck 152 (in Figure 4, the neck 152 is at X length in the axial direction). Thereby, when the guide post 151 is located in the first section 145, the guide post 151 can be limited by the two groove walls (142, 142') in the Z-axis direction. Specifically, as shown in Figure 5, when the guide post 151 initially contacts the opening 143, since there is a margin between the guide post 151 and the two groove walls (142, 142'), the first guide plate 14 can allow the second guide plate 15 to deviate slightly from the guide direction L2, so that the guide post 151 can easily enter the first section 145 through the opening 143. Before the guide post 151 enters the second section 146, when the guide post 151' is located at the opening 143, there is the same margin between the guide post 151' and the two groove walls (142, 142'), so that the guide post 151' The column 151' can be easily entered into the first section 145 through the opening 143. As shown in Figure 6, when the guide post 151 moves to the second section 146, the thickness D3 of the second section 146 is substantially equal to the width of the neck 152 (in Figure 4, the width of the neck 152 in the X-axis direction length), so the guide column 151 can be limited in the Z-axis direction by the two groove walls (142, 142') in the second section 146, so that the movement trajectory of the second guide plate 15 can be limited in the guide direction. L2. When the second guide plate 15 moves along the guide direction L2 and the guide post 151 is located at the stopper 144 , the plug portion 121 can be accurately connected to the connection slot 111 . In some embodiments, the position where the plug-in part 121 is connected to the connecting slot 111 can determine the height of the stopper 144 of the guide slot 141 in the Y-axis direction, so that when the guide post 151 is located at the stopper 144, the first The two guide plates 15 can be limited to an appropriate height to connect the plug portion 121 to the connection slot 111 .

As shown in FIG. 6 again, in some embodiments, a length D4 of the first section 145 is greater than a length D5 of the second section 146, and the distance between the guide posts (151, 151') is less than the length of the first section 145. The length of section 145 is D4. Thus, when each guide post (151, 151') of the second guide plate 15 does not enter the first section 145, since the first section 145 has a narrow thickness D2 (see Figure 5), The guide post 151 can be easily aligned and inserted into the first section 145 . When the guide post 151 moves from the first section 145 to the second section 146, since the distance between the guide posts (151, 151') is less than the length D4 of the first section 145, the guide post 151 Before moving to the second section 146, the guide post 151' can be easily aligned and entered into the first section 145. In this way, when each guide post (151, 151') is located in the first section 145, if the second guide plate 15 causes shaking or deflection during operation, or the second guide plate 15 is not completely When parallel to the first guide plate 14, the second guide plate 15 can still be assembled on the first guide plate 14 with a slight deviation from the guide direction L2, and the guide posts 151 can be positioned on the two groove walls (142, 142 ') to easily enter the second section 146, so that the user can assemble the second guide plate 15 to the first guide plate 14.

As shown in FIG. 3 , in some embodiments, the first guide plate 14 is provided with at least one auxiliary guide groove 147 , the auxiliary guide groove 147 is parallel to the guide groove 141 , and the second guide plate 15 is provided with an auxiliary guide post. 154. The auxiliary guide post 154 is accommodated in the auxiliary guide groove 147 along the guide direction L2. Among them, when each guide column (151, 151') of the second guide plate 15 is located in the guide groove 141, and the auxiliary guide column 154 is located in the auxiliary guide groove 147, each guide column (151, 151') The auxiliary guide post 154 can form a three-point limit on the first guide plate 14 so that the second guide plate 15 can move relative to the first guide plate 14 more stably. In some embodiments, as shown in FIG. 3 , the length of the guide groove 141 is greater than the length of the auxiliary guide groove 147 . Thus, when the guide post 151 is located in the guide groove 141 and the guide post 151' is not yet located in the guide groove 141, the auxiliary guide post 154 has entered the auxiliary guide groove 147, so that the guide post 151 and the auxiliary guide post 154 are not in the guide groove 141. 154 can achieve the stabilizing effect of two-point fixation. When each guide post (151, 151') is located in the guide groove 141, and the auxiliary guide post 154 is located in the auxiliary guide groove 147, each guide post (151, 151') and the auxiliary guide post 154 can function The three-point limiting effect ensures that during the insertion process of the plug-in part 121 and the connection slot 111, the movement trajectory of the plug-in part 121 can be maintained in the assembly direction L1. In some embodiments, the auxiliary guide groove 147 has another stopper 148. When each guide post (151, 151') is located in the guide groove 141 and the guide post 151 is located at the stopper 144, the auxiliary The guide post 154 can be located just at the stopper 148 , whereby the length of the auxiliary guide groove 147 can be determined based on the horizontal height difference between the guide post 151 and the auxiliary guide post 154 (height on the Y-axis in FIG. 3 ).
