[0034] The first threaded portion is located at a side away from the edge of the A plate 141, the second threaded portion is located at a side close to the edge of the A plate 141, the first threaded portion is located at a side away from the edge of the B plate 142, and the second threaded portion is located at a side close to the edge of the B plate 142. The first threaded hole portion is a first column, a second column and a third column arranged in parallel, the first column is two threaded holes A143 arranged at intervals, the second column is three threaded holes B144 arranged at intervals, and the third column is a threaded hole C145, the second threaded portion is a fourth column and a fifth column parallel to the first column, the fourth column is three threaded holes D146 arranged at intervals, and the fifth column is three threaded holes E147 arranged at intervals; the threaded holes A143, threaded holes B144, threaded holes C145, threaded holes D146 and threaded holes E147 are arranged alternately.

[0035] The longitudinal telescopic component includes a first longitudinal tube 2 and a first connecting buckle plate 21, the first connecting buckle plate 21 is welded to one end of the first longitudinal tube 2, and a connecting hole A23 is provided on the first connecting buckle plate 21; the transverse telescopic component includes a first transverse tube 3 and a second connecting buckle plate 22, the second connecting buckle plate 22 is welded to one end of the first transverse tube 3, and a connecting hole B24 is provided on the second connecting buckle plate 22; specifically, the second connecting buckle plate 22 is inserted into the X-axis cavity, and the second connecting buckle plate 22 is connected to the B plate 142 by means of screws 4, and the first connecting buckle plate 21 is inserted into the Y-axis cavity, and the first connecting buckle plate 21 is connected to the A plate 141 by means of screws 4. The bending part of the L-shaped plate 11 and the junction of the L-shaped plate 11 and the outer plate 13 are both provided with a limit pin 12; the limit pin 12 is cylindrical, and the limit pin 12 is respectively arranged in parallel along the bending part of the L-shaped plate 11, the junction of the L-shaped plate 11 and the outer plate 13, the junction of the vertical plate 171 and the horizontal plate 172, and the junction of the horizontal plate 172 and the rear plate 153. The limit pin 12 plays the role of clamping the first connecting buckle plate 21 and the second connecting buckle plate 22 to prevent the first longitudinal tube 2 and the first horizontal tube 3 from shaking. In addition, the limit pin 12 is designed to be cylindrical, which reduces the friction between the limit pin 12 and the first connecting buckle plate 21 and the second connecting buckle plate 22 compared with rectangular, triangular and other shapes. The connection hole A23 of the first connection buckle plate 21 and the connection hole B24 of the second connection buckle plate have the same aperture; the aperture of the connection hole A23 is the same as the threaded hole A143, threaded hole B144, threaded hole C145, threaded hole D146 and threaded hole E147. The connection holes A23 in the column closest to the edge of the first connection buckle plate 21 are on the same line as the threaded hole B144 at the outermost edge of the second column and the threaded hole D146 at the outermost edge of the fourth column. Since the setting position of each threaded hole is different from the setting position of the connection hole A23 or the connection hole B24, the setting spacing is different, that is to say, the minimum adjustment accuracy of the utility model is different. In this embodiment, the minimum adjustment accuracy is 2mm to adapt to battery packs of different sizes.

[0036] like Figure 6 As shown, assuming that the second threaded hole A143 in the first column and the first threaded hole D146 on the left side of the fourth column coincide with the connection hole A23, when telescoping is required, screw 4 is unscrewed to make the screw 4 leave the connection hole A23. At this time, the angle seat 1 moves toward the first connection buckle plate 21 with a small step of 2 mm. When the first movement is 2 mm, as shown in FIG. Figure 7As shown, the second threaded hole B144 in the second row and the third threaded hole E147 on the right side of the fifth row are re-aligned with the connection hole A23. At this time, tighten the screw 4 so that the screw 4 passes through the threaded hole and is embedded in the connection hole A23. At this time, the angle seat 1 is fixed. Every time the angle seat 1 moves 2mm, there will always be two connection holes A23 coaxial with the threaded hole. In this embodiment, after every 12mm movement, the screw 4 will return to the first assumption that the second threaded hole A143 in the first row and the first threaded hole D146 on the left side of the fourth row coincide with the connection hole A23. In this reciprocating cycle, the angle seat 1 can move 50mm.
