[0041] As an optional implementation, as shown in Figure 3 , Figure 4 , the limiting assembly comprises a sliding rail seat 4, a limiting groove 5 and a pin shaft 6, the sliding rail seat 4 is sleeved outside the base 32 of the back clip part 3; the limiting groove 5 is U-shaped and symmetrically arranged on the two side plates of the sliding rail seat 4; the pin shaft 6 is arranged on the outer wall surface of the base 32 and is slidably connected with the limiting groove 5; in the state of switching, the external force acts on the clamping plate 31 of the back clip part 3, and drives the base 32 and the pin shaft 6 to slide along the limiting groove 5.

[0042] Further, the number of limiting grooves 5 is four, which are symmetrically arranged on the two side plates of the sliding rail seat 4, for guiding the sliding of the pin shaft 6 and controlling the movement track of the base 32.

[0043] The base 32 is provided with a through hole 321 for the pin shaft 6 to pass through. The number of pin shafts 6 is two, which pass through the base 32 through the through hole 321, so that the ends thereof are respectively slidably connected with the corresponding limiting grooves 5.

[0044] The limiting groove 5 comprises an upper limiting section 51, a transition section 52 and a lower limiting section 53 which are vertically connected in sequence, and the upper limiting section 51 and the lower limiting section 53 extend along the length direction of the plastic body 1.

[0045] When the state of the back clamping part 3 needs to be converted, an external force is applied to the clamping plate 31 to drive the clamping plate 31 to move in the second accommodating cavity 21, and drive the base 32 and the pin shaft 6 to slide along the limiting groove 5, so as to realize the conversion of the state of the back clamping part 3.

[0046] In the first state, the pin shaft 6 slides into the lower limiting section 53, the base 32 is completely located in the accommodating cavity, the clamping plate 31 is located in the second accommodating cavity 21, and the outer wall surface of the clamping plate 31 is flush with the outer wall surface of the shell 2.

[0047] In the second state, the pin shaft 6 slides into the upper limiting section 51, and the base 32 partially extends from the first accommodating cavity 11 to expose the clamping space 33.

[0048] As an optional embodiment, as shown in Figure 3 , Figure 4 The base 32 is connected with the slide rail seat 4 through a first spring 7, and connected with the side wall of the first accommodating cavity 11 through a second spring 8, and the extension directions of the first spring 7 and the second spring 8 are perpendicular to each other.
