The conventional form for the purpose of crime prevention of the thumb turn, which is arranged on the entrance door etc. and is operated by turning the knob to lock and unlock the latch, after the small hole is made in the entrance door etc. A method of installing a security cover or the like shown in FIGS. 3 and 9 has been devised around the thumb turn so that a stick inserted into the indoor side cannot be illegally rotated. This method prevents a rod or the like illegally inserted into the indoor side from directly interfering with the thumb turn, thereby preventing an illegal rotation operation of the thumb turn.

However, according to the above prior art, especially when trying to adopt a security thumb turn with a special structure so that the thumb turn does not unlock against unauthorized rotation operation, Therefore, it is necessary to replace the entire locking mechanism, and a large-scale construction work by a specialist or the like is required. As a result, the cost is increased, and a large amount of money is required.

In addition, a rod or the like illegally inserted into the indoor side cannot directly interfere with the thumb turn, so that a cover or the like for preventing the thumb turn from rotating illegally is centered around the thumb turn. The installation method is not preferable in terms of safety, because when the thumb turn is locked and unlocked, there is a possibility that the hand may be damaged at the corner of the cover located in the immediate vicinity of the thumb turn. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a thumb-turn picking structure for the purpose of crime prevention which can be easily locked and unlocked by anyone with little cost and easily attached to the prior art.

In addition, the second invention is a thumb turn knob structure which is arranged on the entrance door or the like and is operated to rotate and operate the knob, so that the latch can be locked and unlocked. Is attached to the fitting groove of the pseudo-pick part with a fixing bracket after the ready-made knob part is detachably fitted, and the outer shape of the pseudo-pick part is spherical or coaxial with the rotation axis of the knob part. It is a thumb turn picking structure characterized by being formed into a columnar shape or a similar shape.

According to the first invention, in the thumb turn picking structure, the outer shape of the picking part is formed into a spherical shape, a cylindrical shape coaxial with the rotation axis of the picking part, or a similar shape, so that it is illegally inserted into the indoor side. Even in the case of directly receiving interference from a stick or the like, there is basically no part where the stick or the like is caught, and it is very difficult to operate the thumb turn illegally, resulting in a large crime prevention effect.
