A limit earthing snap for earthing wires is a component for earthing wires. Its main function is to quickly and conveniently connect the earthing wire to the equipment or the earthing body, and at the same time has a certain limiting function, improving the installation efficiency and ensuring the reliability and safety of the earthing connection.

[0003] Currently, most of the limit earthing snaps on the market are in a U-shaped form. When fixing, it is necessary to manually rotate the lower rotating rod to move the lowest clamping plate upward to complete the fixation. However, it is necessary to connect to the conductive copper wire of the earthing wire first. After being connected to the copper wire, affected by the gravity of the copper wire itself, the opening will rotate upward to become a U-shaped, resulting in the snap falling off the wire, which is not convenient for installation and fixation, thus reducing the work efficiency. Therefore, improvements are needed. Summary of the Invention

[0045] Preferably, the right end of the storage slot 201b is blocked by a baffle 201f, and the storage block 201c is pushed to the left by the limiting spring 201e, so that the storage block 201c drives the pawl 201d to move, so that the pawl 201d clamps the ratchet 201a to the right, limiting the rotation of the threaded main rod 101d, so that the fixing assembly 102 can operate normally.

[0046] Furthermore, the connection assembly 202 includes a threaded hole 202a disposed on the right side of the connection frame 101a, a connection threaded nail 202b disposed inside the threaded hole 202a, and a gasket 202c disposed on the connection threaded nail 202b.

[0048] In summary: the connection frame 101a and the grounding wire are connected together by connecting the threaded nail 202b and the gasket 202c, and then the arc at the top of the connection frame 101a is used to connect the wire to the connection frame 101a from the top, left and right directions. Then, the threaded main rod 101d is rotated so that the threaded main rod 101d drives the fixed block to move upward, thereby clamping the wire through the arc at the top of the connection frame 101a and the fixed block to complete the installation of the equipment.

[0049] Example 3, reference Figure 2 to Figure 5 , which is the third embodiment of the present invention, comprising: the control component 203 comprises a long groove 203a arranged on the front and rear sides of the connecting frame 101a, a moving groove 203b arranged inside the long groove 203a, a moving long rod 203c arranged inside the long groove 203a, a synchronization rod 203d arranged on the moving long rod 203c, an extrusion spring 203e arranged on the synchronization rod 203d, a driven buckle 203f arranged on the moving long rod 203c, and a connecting buckle 203g arranged on the arc hook 102a.

[0050] Among them, the long groove 203a is used to place the movable long rod 203c so that it can move up and down inside. The movable groove 203b is used to place the extrusion spring 203e, so that the extrusion spring 203e can push the synchronization rod 203d, so that the synchronization rod 203d pushes the movable long rod 203c to move downward synchronously. The driven buckle 203f and the connecting buckle 203g are set to facilitate the arc hook 102a to control the movement of the movable long rod 203c.

[0051] Preferably, the arc hook 102a is pressurized by an electric wire so that the connecting buckle 203g on the right side of the arc hook 102a pushes up the driven buckle 203f, thereby moving the driven buckle 203f upward, and then the moving long rod 203c is moved up and down inside the moving groove 203b. After the connecting buckle 203g on the arc hook 102a is separated from the driven buckle 203f, the extrusion spring 203e pushes the synchronization rod 203d downward, thereby causing the two moving long rods 203c to move downward synchronously.

[0052] Furthermore, the linkage assembly 204 includes an inclined groove 204a arranged on the lower side of the moving long rod 203c, a connecting through hole 204b arranged on the storage block 201c, and a linkage rod 204c arranged inside the connecting through hole 204b.

[0053] The inclined groove 204a is used to control the left and right movement of the linkage rod 204c, and the connecting hole is used to connect the linkage rod 204c and the placement block 201c, so that the placement block 201c moves along with the linkage rod 204c.

[0054] Preferably, when the movable long rod 203c moves upward, the inclined slot 204a can drive the connecting rod 204c to move together, so that the connecting rod 204c drives the placement block 201c to move, and then the pawl 201d on the limiting component 201 moves along with it.

[0055] Furthermore, the length of the movable rod 203c is 68 mm, the distance between the hole for installing the synchronization rod 203d and the top of the movable rod 203c is 20.08 mm, the outer diameter of the main rod is 8.5 mm, the total height of the connecting frame 101a is 113.5 mm, the width is 35 mm, and the length is 57.6 mm.

[0056] In summary: by setting the top of the connecting frame 101a to be arc-shaped, when the connection with the wire that needs to be connected to the grounding wire is completed, the top arc of the connecting frame 101a is connected to the wire, and by contacting the wire from the front, back and top directions, the grounding wire will not be detached after being connected, making the equipment fixation simpler. In addition, an arc hook 102a is provided at the top arc of the connecting frame 101a. When connected to the wire, the wire will squeeze the arc hook 102a, so that the connecting buckle 203g on the right side pushes up the driven buckle 203f, so that the movable long rod 203c moves upward, and through the inclined groove 204a and the connecting rod 204c on the movable long rod 203c, the storage block 201c moves to the right, thereby controlling the pawl 201d and the ratchet 201a to separate, and releasing the restriction on the threaded main rod 101d, so that the on-site operator can drive the fixing plate 102c to clamp the wire upward by rotating the threaded main rod 101d again to complete the connection of the grounding wire.
