As long as the original key is passed through a simple copy machine in a general lock shop, It can quickly copy a new key with exactly the same pin slot, and its many shortcomings are caused by many loopholes in theft prevention because of the ease of copying. Therefore, how to improve the designer against the loopholes in the security caused by the easy copying of the above-mentioned conventional round-rod key is the difficulty to be solved by the present invention. The main object of the present invention is to provide an improved structure of a round-rod-type key. The specially-designed pin nail groove is attached to the surface of the round-rod-type key so that it cannot be copied on the market to ensure the uniqueness of the key. Anti &

Description of Invention (2) ---- Those who have progressive effects. Technical means to solve the problem ... In order to achieve the above-mentioned object, the present invention is mainly provided on the surface of the round rod key with a plurality of non-deep tip nail grooves, and two longitudinal grooves are recessed on both sides of the round rod key, of which Partial nail grooves can be milled into semi-circular arc grooves of different depths in the radial direction between the two longitudinal grooves on the surface of the round rod key; 俾 can be inserted into the keyhole of the center body of the lock body for unlocking or locking Operator. [Embodiment] The rest of the following is a detailed example with the drawings to introduce the structure of the present invention in detail, and the functional benefits it can achieve as follows; as shown in Figure 3 is a three-dimensional exploded schematic view of the present invention, It is mainly provided with several nail grooves 3 of different depths on the surface of the round rod key 30, and two longitudinal grooves 32 are recessed on both sides of the round rod key 30. Some of the nail grooves 31 can be The rod-shaped key 30 has two longitudinal grooves 32 on the surface and is milled into semi-circular arc grooves 33 with different depths in the radial direction; 俾 can be inserted into a lock body 20 and the key hole 2 11 of the central lock body 2 丨 for unlocking or locking. Operator of the lock. As shown in FIG. 4, which is a schematic cross-sectional view of a lock body, the inner core body 21 can be provided with inner nails 2 of different lengths from different angles, and each inner nail 212 is grouped on the outer side. It is assumed that an outer tip nail 22 is pushed together by a spring 23 and protrudes out of the keyhole 2 丨 1 of the lock body 2 in a normal state; and the positions of the inner tip nails 2 1 2 all fall exactly in a circle Within the spike groove 3 丨 of the lever-shaped key 30 and the semicircular arc groove 33. As shown in FIG. 5, a schematic diagram of another embodiment of the present invention is shown. When the round-rod-shaped key 30 of the present invention is inserted into the key hole 211 and the inner tip nails 21 2 are first opened,
