[0039] In the application, the detachable connection mode of the detachable piece 70 and the connecting arm can be magnetic attraction connection, positioning column and positioning hole connection, or a combination of magnetic attraction connection and positioning column and positioning hole connection.

[0040] Referring to Figure 3For example, in the case of magnetic connection, the magnetic connection mode can be set as follows: the first magnetic member 90 is arranged on the connecting arm, the second magnetic member 80 corresponding to the position of the first magnetic member 90 is arranged on the detachable member 70, and the detachable member 70 is detachably connected with the connecting arm through the first magnetic member 90 and the second magnetic member 80. In the present application, at least one of the first magnetic member 90 and the second magnetic member 80 is a magnet, and the other is a magnet or a magnetic metal that can be attracted by a magnet.

[0041] In some example implementation scenarios, the magnetic connection mode can be set as follows: a plurality of (which can be one) magnets are arranged on the detachable member 70, and a plurality of (which can be one) magnetic metals (for example, iron blocks) are arranged on the connecting arm or the connecting arm is made of magnetic metal; or a plurality of magnets are arranged on the connecting arm, and a plurality of magnetic metals are arranged on the detachable member or the detachable member is made of magnetic metal.

[0045] For example, in the mixed connection mode combining the magnetic attraction connection and the positioning column positioning hole connection, the magnetic attraction metal 90 and the positioning column 100 can be arranged on the detachable part 70, and the magnet 80 and the positioning hole 110 can be arranged on the connecting arm. Alternatively, the magnet 80 and the positioning hole 110 can be arranged on the detachable part 70, and the magnetic attraction metal 90 and the positioning column 100 can be arranged on the connecting arm. Alternatively, the magnetic attraction metal 90 and the positioning column 100 can be arranged on the detachable part 70, and the magnet 80 and the positioning hole 110 can be arranged on the connecting arm. Alternatively, the magnetic attraction metal 90 and the positioning hole 110 can be arranged on the detachable part 70, and the magnet 80 and the positioning column 100 can be arranged on the connecting arm. In the implementation of the mixed connection, the arrangement of the magnet 80 and the magnetic attraction metal 90 can further enhance the firmness between the detachable part 70 and the connecting arm, so that the pull-out force required for the detachable part 70 to be separated from the connecting arm reaches the design standard.
