Protection, when the user accidentally loses foot, can be pulled by the rope to prevent the user from falling down, and can easily and quickly work when fastening and unfastening the safety hook.

The traditional safety hook is a one-piece buckle, which is easy to open due to the impact of external force, and the safety of use is not good. Therefore, a two-stage safety hook is created, as shown in the seventh figure. The utility model is a conventional two-stage opening safety hook, which comprises: a hook body 10, a closing member 20 and a control handle 30, wherein the hook body 10 is provided with a through hole 101 at one end and a hook portion at the other end.

The member 20 can be elastically pivoted in the hook portion 102 by the first pivot 40 to close or open the opening 103. The control handle 30 is coupled to a second pivot 50 to pivot relative to the opening 103 of the hook body 10. On the side, a second spring 70 is disposed between the control handle 30 and the hook body 10, so that the control handle 30 can be elastically pivoted on the outer side of the hook portion 102 by the second pivot 50, and the closure member 20 is provided at one end. a limiting portion 201 is arranged along with the control handle 30. The limiting portion 201 is coupled to a limiting member 80. The control handle 30 has a lateral direction. 301 with a longitudinal arcuate track 302, the longitudinal and the transverse rail 302 rail 301 remain open relationship, and the closure member 20 to limit the stopper portion 201 through the transverse rail 80 of the binding 301, so that the handle 30 and the closure member 20 a cascade relationship.

In the normal state, the limiting member 80 is engaged with the end of the transverse rail 301 away from the longitudinal rail 302, so that the limiting member 80 is blocked by the lower side edge of the transverse rail 301, and the closing member 20 cannot be centered on the first pivot 40. Pivot. Only as shown in the eighth figure, the control handle 30 is pressed in the direction of the closure member 20, and the limiting member 80 is allowed to enter the longitudinal rail 302, so as to release the restriction function of the control handle 30 on the closure member 20, and the closure member 20 is oriented toward the control. The shank 30 is biased at an angle, and the driving restriction member 80 is displaced in the circumferential direction in the longitudinal rail 302 to open the opening 103 of the hook body 10.

However, the conventional two-stage opening safety hook has the advantages of avoiding accidental opening due to external force collision and effectively increasing the opening, so that the hooking or unhooking operation is smoother and faster. However, when the hooking or unhooking operation is performed, the control handle 30 is pressed against the closing member 20, and then the limiting member 20 is biased by a force in the direction of the control handle 30, so that the limiting member 20 is biased toward the control handle 30. An angle is opened to open the opening 103 of the hook body 10. Therefore, the handle 30 must be pressed by one hand during the unhooking operation, and the closure member 20 is pulled by the other hand, and the hands are simultaneously operated, which causes troubles in hooking and uncoupling operations, and In addition to the two-hand operation as described above, the user often presses the handle 30 with one hand, and the hook is struck by the limit member 20 to the object to be hooked, and the limit member is made by the force of the tapping. 20 is biased at an angle to the handle 30 to open the opening 103 of the hook body 10. Although the hook operation is relatively simple, it is easy to hit the user's hand when striking, causing injury to the user.
