[0068] It should be understood that by inserting the first locking portion and the second locking portion into two different locking grooves 430 together, the locking of the control slider 610 and the locking groove 430 is made more stable, and when the control slider 610 is in the locking position, the control slider 610 is more reliable.

[0069] In this embodiment, the first locking portion and the second locking portion are inserted into two adjacent locking grooves 430. As another embodiment, they may also be inserted into two locking grooves 430 with one locking groove 430 in between.

[0070] Refer to Figure 2 As shown, in some specific embodiments of the present utility model, the limiting abutting portion 130 includes an abutting plate 131, two limiting plates 132 connected to opposite sides of the abutting plate 131, and a covering plate 133. The abutting plate 131 and the limiting plates 132 are both connected to the top surface of the mounting plate portion 112 and are integrally formed with the mounting plate portion 112. The two limiting plates 132 are opposite and spaced apart along the first direction to guide and control the sliding of the sliding block 610 along the second direction. The abutting plate 131 is disposed on the side of the control slider 610 away from the sliding member 400 to limit the sliding of the control slider 610 along the second direction. The covering plate 133 covers the tops of the abutting plate 131 and the limiting plates 132 and is detachably connected to the mounting plate portion 112. Among them, the covering plate 133, the abutting plate 131, the two limiting plates 132, and the top surface of the mounting plate portion 112 enclose a receiving groove. After the control slider 610 is installed, the limiting plate 132 restricts the sliding of the control slider 610 along the second direction.

[0071] In this embodiment, the abutting plate 131, the limiting plates 132 and the mounting plate portion 112 are integrally formed. The abutting plate 131, the limiting plates 132 and the mounting plate portion 112 form a pre-placement position. The control slider 610 is pre-installed in the pre-placement position, which makes the assembly of the control slider 610 more convenient. Then, the covering plate 133 is covered on the tops of the limiting plates 132 and the abutting plate 131 to form a receiving groove and complete the installation of the control slider 610, making the assembly of the control slider 610 more convenient.

[0072] Refer to Figure 2 As shown, in some specific embodiments of the present utility model, the front and rear control member 600 further includes a control line 620 connected to the control slider 610 and a reset elastic member 630. The reset elastic member 630 is disposed between the control slider 610 and the abutting plate 131. The control line 620 passes through the abutting plate 131 and is used to drive the control slider 610 to move relative to the receiving groove along the second direction.

[0073] It is understandable that controlling the control slider 610 in a wire-controlled manner is more convenient for users.

[0074] In this embodiment, when an external force acts on the control line 620, it will drive the control slider 610 to disengage from the locking groove 430. The control slider 610 squeezes the reset elastic member 630, and the abutting plate 131 supports the reset elastic member 630. The reset elastic member 630 compresses and stores elastic potential energy. When the external force is withdrawn, the reset elastic member 630 drives the control slider 610 to insert into the locking groove 430 to lock the seat frame 100. Among them, the reset elastic member 630 is a compression spring.

[0075] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
