A second strip groove 615 that passes through the top and bottom walls of the second slider 614 is provided on the side of the second slider 614 close to the second pressure rod 612. A second top member 616 is movably provided inside the second upper seat 61 at a position corresponding to the position below the second slider 614. The second slider 614 can move between the position of aligning and staggering the second follower 613 with the upper end opening of the second strip groove 615. A tenth A top spring 617 is used to apply an elastic force to the second slider 614 to move in the direction where the second follower portion 613 and the upper end opening of the second strip groove 615 are offset. An eleventh top spring 618 is also provided. The second top piece 616 is elastically opposed to the bottom wall of the second slider 614 through the elastic force applied by the eleventh top spring 618. When the second slider 614 moves to the position where the second follower portion 613 is aligned with the upper end opening of the second strip groove 615, the elastic force applied by the eleventh top spring 618 can force the upper end of the second top piece 616 to extend into the second strip groove 615 to fix the second slider 614. When the second pressure rod 612 moves to force the second telescopic member 151 to exit the third insertion hole 611, the second following portion 613 moves to force the second top member 616 to exit the second strip groove 615 to release the lock of the second slider 614. After the second slider 614 is unlocked, the fifth top spring 517 forces the second slider 614 to move in the direction close to the second pressure rod 612, so that the second top spring 204 is staggered with the second strip groove 615 and elastically resists the bottom wall of the second slider 614. At this time, the second following portion 613 elastically resists the second strip groove 615. When the second pressure piece moves upward (for example, the second pressure piece is lifted by external force, or the second pressure piece is lifted by the second telescopic member 151 when the second angle seat 15 is installed), the second following portion 613 can be driven to move upward to exit the second strip groove 615, so that the second slider 614 can move in the direction where the upper end opening of the second strip groove 615 is staggered with the second following portion 613 to lock the second pressure piece.
