Moreover, between the joint surfaces of the hook part 12 of the hook body 1 and the movable piece 22 joined thereto, an engaging means 25 such as a groove and a protrusion, a hole and a pin, etc., which engage and disengage with each other, is provided so that the movable piece 22 This prevents lateral displacement of the hook portion 12 and separation of the hook portion 12 from the movable piece 22.

The present invention is characterized by means for regulating the motion of the movable body 2 and the fixed rope 11 in a complex manner by the operation of the locking mechanism 3. A through hole 19 with a bent upper part is opened, and a fixing means 11 consisting of a chain whose base end is fixed to the lower part of the main body 1 is removably inserted into the through hole 19, and a fixing cable protruding from the opening end of the hole is inserted. A retaining rod 11a is attached to the tip of the fixed rope 11 to maintain the protruding state of the tip, and a communication hole 45 is provided perpendicularly between the shaft hole 14 and the through hole 19, and the fixed rope 11 is attached to the center of the hole 45. A pinion 46 having the same pitch as that of the chain ring of the fixed cable 11 is mounted on a shaft, and a rack 47 corresponding to the pinion 46 is formed on the operating shaft 31. When the actuating shaft 31 is locked, the fixed rope 11 is simultaneously locked.

FIG. 4 shows a second embodiment of means for regulating the motion of the movable body 2 and the fixed cable 11 in a complex manner. The pin 48 engages an operating pin 48 having one end of the guide 48a with the operating shaft 3.
1 and urges the other end guide 48b toward the hole recess 51 of the through hole 19 with a spring.
1 is always pressed and fixed to the wall of the recess 51. In this case, when the guide element 48a and the protrusion 50 are disengaged, the fixed cable 11 is released from the bias of the operating pin 48 and can move up and down against the spring 49.
Therefore, when using this operating pin 48, there is no need to consider the engagement of the chain ring of the fixed cable 11, and the fixed cable 11 is not limited to a chain.

Therefore, when the hook of the present invention is used to connect and lock the article 7 to be prevented from theft to the fixed object 6, first, the movable piece 22 of the hook of the present invention is normally hooked by the elastic force of the operating shaft 31. The opening 1 is joined to the portion 12.
