In this embodiment, two first sliding grooves 421 are disposed on the driving member 42, the length extending direction of the first sliding grooves 421 is obliquely intersected with the sliding directions of the driving member 42 and the operating member 41, the engaging portion 411 is disposed in the first sliding groove 421 and can be slidably disposed along the length extending direction of the first sliding groove 421, and one side wall of the first sliding groove 421 extending along the length direction thereof is the inclined surface 421a engaged with the engaging portion 411. The fitting portion 411 is a slide pin.
Preferably, the two first sliding grooves 421, i.e., the two inclined surfaces 421a, are symmetrically disposed with respect to the center of the base 1.
In the present embodiment, the fitting portion 411 is provided on the operating member 41 so as to be slidable in the sliding direction of the operating member 41. Thus, when the operating member 41 on one side is operated to slide outwardly relative to the base 1 to unlock the locking mechanism, the operating member 41 on the other side can be fixed relative to the base 1 and remain stationary.
Specifically, the operating element 41 is provided with a second slide groove 412 extending in the sliding direction thereof, and the engaging portion 411 is slidably provided in the second slide groove 412 in the longitudinal extending direction of the second slide groove 412. When the locking mechanism is in the locked state, the engaging portion 411 abuts on an end portion of the second sliding groove 412 near the center of the base 1. Thus, when the operating element 41 on either side is operated to slide outward, i.e., leftward, relative to the base 1 when the operating element 41 on the left side is operated in the locked state of the locking mechanism, the engaging portion 411 abuts against the end of the second sliding slot 412, so that the engaging portion 411 is driven to slide to the left side of the base 1 synchronously with the operating element 41 on the left side. In this process, the driving member 42 is slid forward by the engagement of the engaging portion 411 on the left side and the side wall of the first sliding groove 421.

In the connecting member 43, at least the intermediate connecting portion 433 has elasticity, and in this embodiment, the entire connecting member 43 is made of an elastic material having elasticity.
The child safety seat further includes an elastic member 5 for driving the driving member 42 to return after the locking mechanism is unlocked, in this embodiment, the elastic member is a spring, one end of the spring is disposed on the driving member 42, and the other end of the spring is disposed on the base 1. When the driving member 42 is returned, the connection between the driving member 42 and the locking member 3 is such that the operating member 41 and the locking member 3 are also returned to the position in which the locking mechanism is in the locked state by the cooperation between the driving member 42 and the operating member 41.
Of course, the driving member 42 and the left and right locking members 3 can be matched with each other, for example, the driving member 42 and the left and right locking members 3 are matched with each other through an inclined surface, so that when the driving member 42 slides forward relative to the base 1, the left and right locking members 3 are driven to slide and be released from the locking groove 21.
When the child safety seat is in use, the locking mechanism is in a locked state, as shown in fig. 1, 2, 5 and 6.
When the sitting posture of the seat needs to be adjusted, the unlocking mechanism is operated to unlock the locking mechanism, and the specific operation process is as follows: when the operating part 41 on any side is pulled to the outside of the base 1, for example, the operating part 413 on the operating part 41 on the right side is held to pull the operating part 41 outwards, the operating part 41 slides outwards, that is, rightwards relative to the base 1, the matching part 411 arranged on the operating part is driven to slide rightwards synchronously, and the driving part 42 slides forwards through the matching of the matching part 411 and the side wall of the first sliding chute 421. When the driving member 42 slides forward, the connecting members 43 on both sides are stretched to generate elastic deformation, and the connecting members 43 on both sides simultaneously pull the locking members 3 connected therewith to slide toward the direction close to the center of the base 1 until the locking members 3 on both sides are disengaged from the locking grooves 21, so that the locking mechanism is unlocked, and at this time, the angle between the base 1 and the housing 2 can be adjusted. When the driver 42 slides forward, the left engaging portion 411 slides leftward in the left second slide groove 412, while the left operating member 41 remains stationary. After the locking mechanism is unlocked, the engaging portion 411 on the right side is still located at one end portion close to the center of the base 1 in the second sliding groove 412 on the right side, and the engaging portion 411 on the left side is located at one end portion away from the center of the base 1 in the second sliding groove 412 on the left side, as shown in fig. 7 and 8.
When the angle between the base 1 and the housing 2 is adjusted to a proper position, the operating member 41 is released, the force of the engaging portion 411 on the sidewall of the first sliding slot 421 disappears, the driving member 42 slides backward under the elastic force of the elastic member 5, and in this process, the connecting members 43 on the left and right sides gradually return to the original shape and drive the locking member 3 connected thereto to slide in the direction of inserting into the locking slot 21. When the driving member 42 slides backward, the side wall of the first sliding slot 421 and the engaging portion 411 act to make the right engaging portion 411 drive the right operating member 41 to slide toward the center of the base 1, i.e. to the left, and the left engaging portion 411 also slides toward the center of the base 1, i.e. to the right, in the left second sliding slot 412 until the components slide to the position when the locking mechanism is in the locked state.
