When the stopper pin 131 is located at the lower end of the slide groove 111, the connecting portion 130 is located at the second position, and the connecting portion 130 is rotatable about the axial line of the stopper pin 131 with respect to the main body portion 110.

The connecting portion 130 (e.g., a side portion of the connecting portion 130) is formed with a first stopper portion 132, and the connecting portion 130 can be held at a predetermined position by a locking member 170 engaged with the first stopper portion 132, wherein the predetermined position is between the first position and the second position; in this disclosure, the first limiting portion 132 may be disposed in a plurality of lengths along the length direction of the connecting portion 130, so that the connecting portion 130 has a plurality of extending lengths, and it is convenient for users with different heights to flexibly adjust the height of the product, thereby improving the user experience.

In another embodiment, a second position-limiting portion 133 is formed at the upper end of the connecting portion 130, and when the connecting portion 130 is at the second position, the connecting portion 130 can be maintained at a predetermined angle by a locking member 170 engaged with the second position-limiting portion 133.

When the surface cleaning apparatus 100 of the present disclosure is in use, the connecting portion 130 is in the first position, where a general surface to be cleaned can be cleaned, and on the other hand, when it is desired to clean the sofa bottom and the bed bottom surface to be cleaned, the locking member 170 is unlocked, so that the connecting portion 130 can slide relative to the main body portion 110.

The locking member 170 may be driven by an electromagnet or the like, so that the locking member 170 can be controlled by a button, and in this case, the button may be disposed on the handle for the user to operate.

On the other hand, the locking member 170 may also be manually moved by the user to unlock the connecting portion 130, and at this time, the button may be connected to the locking member 170 through a transmission structure, so that when the user triggers (e.g., presses) the button, the locking member 170 can be directly separated from the first position-limiting portion 132 or the second position-limiting portion 133 to unlock the connecting portion 130.

The locking member 170 may be reset by a spring or the like, so that the locking member 170 may enter the first position-limiting portion 132 or the second position-limiting portion 133 without operation, and the relative position between the connecting portion 130 and the main body portion 110 may be locked.

When the connecting portion 130 is moved to the second position, the main body portion 110 is controlled to rotate the connecting portion 130 relative to the main body portion 110 and form a predetermined angle, and at this time, the locking member 170 cooperates with the second limiting portion 133 to keep the main body portion 110 and the connecting portion 130 at the angle.

In one embodiment, the second position-limiting portion 133 may be formed in a plurality of numbers, and enables the connecting portion 130 and the main body portion 110 to be stably maintained at a plurality of angle values, and in a preferred embodiment, the connecting portion 130 and the main body portion 110 can be maintained at 120 °, and thus a distance L between the cleaning portion 120 and the main body portion 110 can be greater than or equal to 50cm, so as to greatly facilitate the cleaning of the bed bottom and the sofa bottom by the user.
