By driving the portion of the driving assembly 30 protruding out of the base 1000, the driving assembly 30 can drive the locking member 20 to slide telescopically, so that the locking member 20 is disengaged from the positioning portion 121 to release the lock, and the operation is convenient. Specifically, the driving assembly 30 includes a release handle 32 and a rotating driving member 31, and the driving member 31 is respectively connected to the locking member 20 and the release handle 32. One end of the release handle 32 is connected to the driving member 31, and the other end protrudes out of the base 1000 for the user to operate. By operating the end of the release handle 32 for the user to operate, the driving member 31 drives the locking member 20 to disengage from the positioning portion 121 to release the lock. It can be understood that the release handle 32 protrudes out of the base 1000 for more convenient operation. The driving member 31 rotates under the action of the release handle 32 to convert the vertical force into the horizontal force. Under the rotation of the driving member 31, the locking member 20 can be extended and retracted in the horizontal direction with the rotation of the driving member 31, so that the locking member 20 can be disengaged from the positioning portion 121 to release the lock.

Since the length of the fixing portion 11 relative to the base 1000 is adjustable, the installation of the child safety carrier and the seat of the present invention is more convenient.

[0053] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are all within the scope of the present invention.
