Referring to fig. 1 and 2, the head 1 includes a telescopic portion 11 that can be extended and retracted in the telescopic hole 61, and a rotating portion 12 that contacts the linkage member 2 and the guide block 4.

The expansion part 11 includes a plane 111 perpendicular to the expansion hole 61 when locking the door, and an inclined plane 112 forming a certain angle with the plane 111.

The rotating portion 12 includes a shoulder 121 having a length and a width larger than those of the telescopic hole 61, and a coupling receiving groove 124 for receiving the coupling 2, wherein the shoulder 121 is provided with a head engaging groove 122, and a shaft groove 123 is provided at a top end of the head engaging groove 122.

Referring to fig. 1 and 3, the linking member 2 includes a shaft 21 received in the shaft slot 123, a first guide protrusion 22 received in the first guide slot 62, and a spring receiving hole 23 for receiving the spring 3.

After the connection, the head 1 can be rotated about the shaft 21.

The length of the first guide groove 62 is greater than that of the first guide protrusion 22, and the widths of the first guide groove and the first guide protrusion 22 are the same, when the first guide protrusion 22 slides in the first guide groove, the linkage member 2 can only move linearly in the length direction of the first guide groove 62, that is, the linkage member 2 can only move linearly in the direction perpendicular to the telescopic hole 61.

With continued reference to fig. 1, 3, 6 ~ and 12, one end of the spring 3 is accommodated in the spring accommodating hole 23, the other end of the spring 3 contacts the spring baffle 63, and the spring baffle 63 is provided with a baffle protrusion 631 having a diameter smaller than that of the spring 3 for preventing the spring 3 from moving, because the spring baffle 63 is fixedly connected with the housing 1, under the natural tension of the spring 3, the spring 3 always has a force that makes the linkage member 2 and the head 1 movably connected with the linkage member 2 move away from the housing 6, and because the linkage member 2 can only move linearly in a direction perpendicular to the retractable hole 61, the tension of the spring 3 makes the linkage member 2 and the head 1 always have a force that extends out of the housing 6 in a direction perpendicular to the retractable hole 61.

Referring to fig. 1, 4, and 6 ~, referring to fig. 12, the guide block 4 is provided with a locking protrusion 41 capable of being inserted into the head slot 122, a second guide protrusion 42 received in the second guide slot 65, and a lever slot 43 for receiving the lever head 51.

In the present invention, the driving lever head 51 is fixedly connected to the driving lever slot 43. Therefore, the guide block 4 is fixedly connected with the guide block shift lever 5, and when the guide block shift lever 5 rotates, the guide block 4 rotates along with the guide block shift lever.

The length of the second guide groove 65 is greater than the second guide protrusion 42, and the widths of the second guide groove 65 and the second guide protrusion 42 are the same, when the second guide protrusion 42 slides in the second guide groove 65, the guide block 4 can only move linearly in the length direction of the second guide groove 65, that is, the guide block 4 can only move linearly in the direction parallel to the telescopic hole 61.

Referring to fig. 6 ~ and fig. 12, in a natural state, the head 1 and the linkage member 2 are always away from the housing 6 due to the natural tension of the spring 3, the telescopic portion 11 extends out of the telescopic hole 61, and the shoulder 121 is clamped inside the telescopic hole 61.

When needing the lock door, handle or external force drive guide block driving lever 5 and use fixed column 64 as the axle anticlockwise rotation, and then drive guide block 4 rotatory, because guide block 4 can only be at the length direction of second guide way 65 on linear motion, guide block 4 downstream back, the protruding 41 card of screens is gone into in the head draw-in groove 122 of rotating part 12, the rotating part 12 can't rotate this moment and can't remove in to casing 6, head 1 is by spacing realization lock door.

When the door needs to be opened, the handle or external force drives the guide block shifting lever 5 to rotate clockwise by taking the fixed column 64 as an axis, the guide block 4 moves upwards along with the guide block and leaves the head clamping groove 122, the limit of the head 1 disappears at the moment, and the compression spring 3 of the head 1 can enable the head 1 to retract into the shell 1.

When the head portion 1 is retracted into the housing 1, the head portion 1 is rotatable in both front and rear directions with the shaft rod 21 as an axis and the shoulder portion 121 as a fulcrum, so that the door can be opened in any direction.

At this time, the head 1 rotates to drive the linkage member 2 to press the spring 3, and under the action of the second guide protrusion 22, the head 1 can only retract into the housing 6 in the direction perpendicular to the telescopic hole 61 and can completely retract into the housing 6. The door can be opened.

The detailed description of the embodiments of the present invention has been presented, and it will be apparent to those skilled in the art that the present invention can be modified and modified without departing from the principles of the present invention, and the modifications and modifications also belong to the protection scope of the claims of the present invention.
