Example two

The first embodiment differs from the first embodiment in that the locking assembly 30 is also capable of locking the latch arm 21 in the unlocked position.

Specifically, the latch arm 21 also has an unlocked position releasing the wheel, and when the latch arm 21 is in the unlocked position, a portion of the locking assembly 30 can extend into the locking position 211 to lock the latch arm 21 in the unlocked position.

Of course, the locking members 32 may be provided in a pair or two pairs, and each of the engaging arms 21 is engaged with the pair of locking members 32.

Meanwhile, the locking assembly 30 further comprises a locking piece resetting piece 33, namely a locking piece resetting torsion spring or a locking piece resetting elastic piece, wherein two ends of the locking piece resetting piece 33 are respectively abutted between the two locking pieces 32 arranged in pairs, so that a resetting force close to each other is provided for the locking ends of the two locking pieces 32 arranged in pairs. Therefore, under the action of the locking piece resetting piece, when the clamping arm 21 rotates to a proper position, the locking end can automatically extend into the notch structure, and automatic locking is realized.

It should be noted that, in this embodiment, the two locking ends are used for locking the locking arm 21 at the locking position and the unlocking position, that is, when the user needs to control the driving portion 31 through the remote terminal to withdraw one locking end from the notch structure, then the wheel can press the pedal 22 to rotate the locking arm 21, and when the locking arm 21 rotates to the locking position, the other locking end extends into the notch structure to lock the locking arm 21. In this way, the provision of the two locking pieces 32 enables the click-on arm 21 to be locked at both the locked position and the unlocked position, thereby preventing the lock mechanism from being used at will.

In this embodiment, a spring member is disposed in the stirring member 34, one end of the spring member is abutted on the stirring member 34, the other end is abutted with a shaft shoulder on the output shaft of the motor, when the driving portion 31 drives the stirring member 34 to move, the stirring member 34 can squeeze the spring member, and the spring member can play a role in buffering and locking when the driving portion 31 drives the stirring member 34 to move.

Example III

The difference from the second embodiment is that the structure of the click arm 21 and the lock 32 is different.

As shown in fig. 11 to 14, the clamping arms 21 are of a unitary structure, one end of each clamping arm 21 is connected with the pedal 22, the other end is provided with a bending section, the distance between the bending sections of the two clamping arms 21 arranged in pairs is reduced along the direction away from the pedal 22, and the minimum distance between the bending sections is smaller than the diameter of the circular section of the tire of the wheel so as to prevent the wheel from falling out of the clamping arms 21. The bending section of the clamping arm 21 can extend out of the base body 10, so that the wheel can be held by the bending section without arranging a separate connecting section 212 and locking pin section 213, and the pretensioning of the wheel is realized.

In this embodiment, the locking member 32 is one, two step structures are formed on the side surfaces of the clamping arm 21 to serve as locking positions 211, and when the clamping arm 21 moves to the locking position, the locking end of the locking member 32 abuts against one step structure, so that the rotation of the clamping arm 21 is blocked, and locking is achieved. When the latch arm 21 moves to the unlocking position, the lock 32 abuts on the other step structure, thereby achieving locking. Of course, there may be a plurality of locking members 32, one locking member 32 being provided at each of the engaging arms 21.
