Detailed Description

The utility model is described in further detail below with reference to the drawings and the detailed description.

As shown in fig. 4 and 5, the present utility model provides a movable lock nose structure, which comprises a sliding seat 5, a sliding block 6, a lock nose 1, a compression spring 7 and an adjusting screw 8.

The sliding block 6 is arranged on the sliding seat 5 and can slide on the sliding seat 5 in a straight line, the lock nose 1 comprises a U-shaped rod 101 and a mounting seat 102, the U-shaped rod 101 is fixed on the mounting seat 102, and the mounting seat 102 is fixed on the sliding block 6 through a fixing screw 103. The U-shaped bar 101 forms a through hole for the bolt to pass through, the hole of the through hole being parallel to the sliding direction of the slider 6.

The sliding seat 5 is provided with a sliding groove 501, and two ends of the sliding groove 501 are respectively provided with a first end plate 9 and a second end plate 10. The first end plate 9 is provided with a screw hole, the adjusting screw 8 is screwed in the screw hole, the end part of the adjusting screw 8 passes through the screw hole and then abuts against the sliding block 6, and the axis of the screw hole is parallel to the sliding direction of the sliding block 6, so that the sliding block 6 can be pushed when the adjusting screw 8 is screwed.
