The locking member 5 is arranged in the first mounting hole 202 and can move axially relative to the first mounting hole 202; the locking member 5 is arranged between the rotating member 4 and the sliding seat 3; the first surface 501 of the locking member 5 opposite to the rotating member 4 is provided with a slide groove 502, and the slide groove 502 extends along the circumferential direction; the slide groove 502 has a first section 5021 and a second section 5022, the first section 5021 and the second section 5022 are connected, and the groove depth of the first section 5021 is greater than the groove depth of the second section 5022; the ball 6 is connected to the rotating member 4; and the ball 6 is arranged in the slide groove 502, and the rotating member 4 is rotated, and the ball 6 is converted between the first section 5021 and the second section 5022, wherein when the ball 6 is in the second section 5022, the locking member 5 presses against the sliding seat 3 to realize the locking of the fixed seat 2 and the sliding seat 3. The present application only requires rotating the rotating member 4 to achieve locking of the fixed seat 2 and the sliding seat 3, and the operation is simple and convenient.

Referring to Fig. 3 and Fig. 5, in some embodiments, the lock seat 1 further comprises an elastic member 7, which is sleeved on the locking member 5, and one end of the elastic member 7 abuts against the locking member 5, and the other end of the elastic member 7 abuts against the sliding seat 3. With the arrangement of the elastic member 7, when the bead 6 is in the first section 5021, the squeezing force of the locking member 5 on the sliding seat 3 disappears, and the locking member 5 moves in a direction away from the sliding under the elastic force of the elastic member 7, so that the sliding seat 3 slides more smoothly relative to the fixed seat 2. In some embodiments, the elastic member 7 is a spring.

3 and 5, in some embodiments, the silicone member 8 is further included, and the silicone member 8 is fixedly connected to the locking member 5 (such as pasting the silicone member 8 on the locking member 5), and the silicone member 8 is arranged between the locking member 5 and the sliding seat 3. The silicone member 8 is added to the locking member 5 so that the silicone member 8 abuts against the sliding seat 3, which can increase the friction between the silicone member 8 and the sliding seat 3, so as to better lock the fixed seat 2 and the sliding seat 3.

3 and 5, in some embodiments, the rotating member 4 is fixedly connected to the handle 9 via screws, the handle 9 extends out of the first mounting hole 202, and the handle 9 is rotated to drive the rotating member 4 to rotate. The setting of the handle 9 facilitates the rotation of the rotating member 4.

Referring to Fig. 5 and Fig. 6, in some embodiments, the lock seat 1 further comprises a screw rod 10 and a threaded sleeve 11, wherein the threaded sleeve 11 is sleeved on the screw rod 10; the sliding seat 3 is provided with a second mounting hole 302 (see Fig. 5), wherein the screw rod 10 and the threaded sleeve 11 are provided in the second mounting hole 302, and the screw rod 10 can rotate relative to the second mounting hole 302.
