Detailed Description

The invention will be described in further detail with reference to the drawings and the detailed description.

Referring to fig. 1, 2, 3, 4, 5 and 6, the basic structure of the clamp of the present invention is similar to that of a conventional clamp, and the clamp comprises a base 1, a clamp button 2, a clamp cover 3 and a torsion spring 4; the clamp cover 3 is arranged on the base 1 through the auxiliary shafts 5, two auxiliary shafts are arranged, the clamp cover can be kept stable during operation, the tail part of the clamp button 2 is arranged on the base 1 through the main shaft 6, the structure of the clamp button can be various, for example, the clamp button in a common folder can be used, in the example, the clamp button in the common folder is taken as an example, the torsion spring 4 is arranged between the clamp cover 3 and the clamp button 2, the torsion spring 4 is sleeved on the main shaft 6, and the torsion spring is provided with the hook 7.

The invention differs from the prior art in that: the clamp further comprises a hook seat 8, wherein a hook piece 9 for hanging the hook 7 is arranged on the hook seat 8, a hook groove 10 is arranged below the hook piece 9, a first inclined surface 11 for guiding the hook 7 to move is arranged above the hook piece 9, and a second inclined surface 12 for guiding the hook 7 to be separated from the hook groove 10 is arranged at the bottom end of the side wall of the hook groove 10;

pressing the clamping button 2, enabling the hook 7 to slide downwards along the first inclined plane 11 after contacting with the first inclined plane 11, and falling into the hook groove 10 under the action of restoring force of the torsion spring 4 to realize locking; the clamping button is pressed again, the hook 7 is separated from the hook groove 10 and slides along the second inclined plane 12 to be separated from the hook seat 8, and unlocking is completed.

The working principle is as follows: the pressing clamp button moves vertically, the hook is firstly contacted with the first inclined surface 11 on the hook piece 9, the hook continuously presses, the hook slides along the inclined surface and falls into the hook groove 10, and the pressing clamp button is released to complete locking operation. When unlocking, the clamping button is pressed, the clamping button is separated from the hook groove, and is separated from the hook piece under the guidance of the second inclined surface 12, so that unlocking is completed. In the process, the torsion spring arm swings or rotates, so that the clamp button cannot deviate, the clamp button cannot be damaged, and the method is particularly suitable for single-hand operation.

As a modification, the projection of the hook 7 on the horizontal plane is intersected with the projection of the first inclined plane 11 on the horizontal plane; the inner wall of the hook piece 9 is positioned at the left side of the hook 7. The intersection of the projection of the hook and the projection of the first inclined plane 11 ensures that the clip button does not need to swing, and the hook can swing and slide into the hook groove along the first inclined plane 11.

What needs to be stated separately is: the left and right position limitations in this example are for convenience of description and should not be construed as limitations on the specific configuration shown. The left and right in this example refer to the orientation of figure 4 of the specification.

Specifically, the hook seat 8 is further provided with a guide seat 13, the guide seat 13 is located below the hook groove 10, the guide seats 13 are respectively provided with a guide surface 14, the left guide surface 14 is used for guiding the hook 7 to enter the hook groove 10, the right guide surface 14 is used for guiding the hook 7 to be separated from the hook groove 10, the right side of the left guide surface 14 is a vertical wall 15, and the right guide surface 14 extends to the right along the vertical wall 15. The guide seat is used for further ensuring the stability of the sliding or moving of the hook in the working process and the stability of the hook in the locking state. In order to facilitate the installation and fixation, the hook seat 8 is fixed on the base by means of welding, rivets 17, screws and the like.

The two torsion spring arms 16 of the torsion spring 4 are respectively connected with the clamp cover 3 and the clamp button 2, and the front ends of the torsion spring arms 16 connected with the clamp button 2 are bending parts serving as hooks 7. The structure facilitates the rotation or swing of the torsion spring arm, and the hook is positioned at the front end of the torsion spring arm, so that the hook can be matched with the hook piece on the hook seat to act, and interference can not be caused.

The movable clasp described in the above embodiment has an elastic reset structure or performance, and can reset through the structure, and also can reset by depending on the material itself. In the example, the elastic reset function of the clasp is realized by the elasticity of the material of the torsion spring.

The clamp button 2 is provided with a press hook 18, and the torsion spring arm 16 is limited by the press hook 18 and is connected with the clamp button 2. The structure can realize that the torsion spring arm can swing, does not influence the smooth swing of the bending part, and can ensure that the torsion spring arm can keep stable.

The clamp is particularly suitable for being used in folders.
