In order to guarantee the hook effect of the sliding rod 5 and the rotating piece 6, the problem that the sliding rod 5 and the rotating piece 6 are easy to separate is avoided, the locking structure further comprises an elastic reset piece, the elastic reset piece is a torsion spring 7 in the embodiment, one end of the torsion spring 7 is connected to the rotating piece 6, the other end of the torsion spring 7 is blocked and limited on the end cover 3, and therefore when one end of the torsion spring 7 rotates along with the rotating piece 6, the other end of the torsion spring 7 can be kept motionless, and self-energy storage of the torsion spring 7 is achieved.
In this embodiment, a sliding groove for installing a sliding structure is formed in the end cover 3, and an annular groove for installing the torsion spring 7 is formed in the side wall of the sliding groove. In this embodiment, the sliding groove includes two parts, one is a sliding groove for guiding the assembling sliding rod 5, the other is a step-shaped rotating member 6 for installing the locking structure, and the annular groove is also arranged on the groove wall of the step-shaped sliding groove. In this embodiment, the pressing plate ejector 8 is sleeved on the sliding rod 5, and the groove wall of the sliding groove is provided with an ejector blind groove for the pressing plate ejector 8 to transversely insert, and the end surface of the elastic piece blind groove can stop the pressing plate ejector 8.
In this embodiment, a cylindrical boss is disposed in the annular groove, and the torsion spring 7 is sleeved on the cylindrical boss when installed.

In this embodiment, a threaded hole is provided in the cylindrical boss, the threaded hole is used for assembling a second screw, a through hole for the second screw to pass through is provided in the rotating member 6, and the rotating member 6 is rotatably assembled on the second screw. In this embodiment, the sliding structure and the locking structure are press-fitted on the end cover 3 through the cover plate 9, and through holes for the first screws and the second screws to pass through are provided in the cover plate 9.
The rotating member 6 in this embodiment has a hooking position for hooking with the slide bar 5 and a unhooking position for unhooking with the slide bar 5 during rotation. In order to realize the function of locking the movable platen 4 by pressing the movable platen 4, in this embodiment, the inclined guide surfaces are provided on the sides of the first hook and the second hook facing each other, so that when the movable platen 4 is pressed and the first hook and the second hook contact, the force acting on the movable platen 4 will generate a component force effect perpendicular to the rotating member 6 under the action of the inclined guide surfaces, thereby pushing the rotating member 6 to rotate, after the rotating member 6 rotates by a certain angle, the first hook will cross the second hook, and then the rotating member 6 will be switched to the hook position again under the action of the torsion spring 7, thereby realizing the mutual hooking of the first hook and the second hook.
In this embodiment, two ends of the torsion spring 7 (i.e., two ends of the steel wire used to form the torsion spring 7) are an axial end and a lateral end, respectively, the axial end extends along the axial direction of the torsion spring 7, and the lateral end is located in the cross section of the torsion spring 7. The rotating member 6 is provided with a limiting hole 601 for inserting the axial end, so that when the rotating member 6 rotates around the second screw, the axial end of the torsion spring 7 can rotate along with the rotating member 6, and the transverse end of the torsion spring 7 can be blocked with the inner groove wall of the annular groove and does not move, thereby realizing the energy storage of the elastic potential energy of the torsion spring 7.
In order to avoid the problem that the movable pressing plate 4 is easy to shake in the pressing process, the stability of the movable pressing plate 4 during pressing is enhanced, two sets of sliding structures and locking structures are arranged on the end cover 3, and two pressing plate elastic pieces sleeved on the sliding rods 5 are correspondingly arranged.
It should be noted that, in this embodiment, the abrasive board 1 is directly clamped and fixed in the middle position of the movable pressing board 4 and the end cover 3, while the two light blocking leaves 2 are respectively provided with a flanging, and the flanging of the two light blocking leaves 2 are respectively clamped and fixed in the two ends of the movable pressing board 4 and the end cover 3.

Due to the loss of pressure of the movable pressing plate 4, both the sanding plate 1 and the two light blocking vanes 2 are out of constraint, thereby realizing the detachability of the sanding plate 1 and the two light blocking vanes 2. When the movable pressing plate 4 is ejected to the opening position, the acting force on the two rotating members 6 is removed, and at this time, the two rotating members 6 are switched to the hooking position again under the action of the torsion spring 7. After the sanding plate 1 and the light blocking leaves 2 are cleaned, replaced or adjusted, the movable pressing plate 4 is pressed, the movable pressing plate 4 can drive the two sliding rods 5 to move downwards, and when the first hooks of the sliding rods 5 are contacted with the second hooks of the rotating pieces 6, the inclined guide surfaces of the first hooks and the second hooks can generate component force effects on acting force applied to the movable pressing plate 4, so that the two rotating pieces 6 can rotate outwards. When the two first hooks pass over the second hooks, the rotating piece 6 can be switched to the hooking position again under the action of the torsion spring 7, and the first hooks and the second hooks are hooked mutually at the moment, so that the upward movement of the two sliding rods 5 is limited, and the movable pressing plate 4 is used for press-fitting and fixing the sanding plate 1 and the light blocking leaves 2 on the end cover 3.

2. An end switch structure according to claim 1, wherein: the two ends of the torsion spring (7) are an axial end and a transverse end respectively, the axial end extends along the axial direction of the torsion spring (7), the transverse end is positioned in the cross section of the torsion spring (7), the rotating piece (6) is provided with a limiting hole (601) for the insertion of the axial end, and the transverse end is blocked with the end cover (3) mutually.
3. An end switch structure according to claim 2, characterized in that: the end cover (3) is provided with a sliding groove for installing a sliding structure, the groove wall of the sliding groove is provided with an annular groove for installing a torsion spring (7), and the sliding structure and the locking structure are fixed in the sliding groove and the annular groove through a cover plate (9).
4. An end switch structure according to claim 1, wherein: the sliding rod (5) is provided with a first hook, the rotating piece (6) is provided with a second hook, and the first hook and/or the second hook are/is provided with an inclined guide surface to drive the rotating piece (6) to rotate when the sliding rod (5) moves towards the rotating piece (6).
5. The end switch structure of claim 4, wherein: the sliding rod (5) is provided with a long hole (501), the long hole (501) extends along the axial direction of the sliding rod (5), and the end cover (3) is provided with a positioning piece inserted into the long hole (501).
6. The lampshade comprises a light blocking blade (2) and/or a frosting board (1), and is characterized in that: the light blocking plate further comprises an end switch structure for clamping and fixing the light blocking plate (2) and/or the frosting plate (1), wherein the end switch structure adopts the end switch structure as claimed in any one of the claims 1 to 5.
7. Lamps and lanterns, including light and lamp shade, the lamp shade includes leaf (2) and/or dull polish board (1) that block light, its characterized in that: the lamp housing further comprises an end switch structure, which employs the end switch structure of any one of the preceding claims 1 to 5.
