It consists of a set, and there are some similarities in configuration to the small ratchet parts of the present invention described later, but this one has a grip pattern (60) on the first body (20) as shown in FIG. ) Is a so-called ratchet driver in which a square shaft functioning as a driver is fixed to the second main body (30) by being inserted through the same straight line, and does not have a function as a ratchet part. Further, the locking member (40) formed on the first main body (20) of this one is inserted into the storage portion (24) penetrating the first main body (20) in the lateral direction and is securely fixed. The first main body (20) is not a structure that is arbitrarily inserted into and fixed to an existing driver.

  As described above, there are various types of drivers that do not have a ratchet function, but a driver having a ratchet function is often required at the work site. Of course, various types of ratchet drivers have existed in the past, but most of them are more expensive than drivers having no function. Also, there are many cases where the ratchet function is not always required depending on the place of use. In such a situation, a driver having both a ratchet function and a normal simple driver function is often required.

  The present invention was devised in view of the above demands, and exists as a small single unit. If necessary, the present invention is inserted into an existing ordinary driver or the like, and the driver has a ratchet function and the ratchet function. It is an object of the present invention to provide a small ratchet part that can function as a normal driver at any time.

  In order to achieve the above object, the present invention is applied to detachably inserted into an existing hexagonal axis replaceable driver that does not have a ratchet function and to function the existing driver as a ratchet driver. The ratchet part is composed of a ratchet body, a ratchet ring inserted into and removed from the ratchet body, and a ratchet bit holder. The ratchet body is inserted into and removed from the existing driver on one end side. A shaft body having a body shaft and an enlarged shaft portion integrally connected to the body shaft and having a diameter larger than that of the rectangular body shaft, and the ratchet ring is inserted into and removed from the enlarged shaft portion. The ratchet bit holder is fixed to one end side so as to be insertable / removable into the enlarged shaft portion, and is attached to the other end side of the ratchet ring. A ring body that is positioned in contact and forms a gear portion therein, and a shaft portion that is integrally connected to the ring body and has an internal corner body hole that is removably fixed to a rectangular shaft body that functions as a driver. A ratchet claw sliding hole through which at least two ratchet claws are inserted and removed via a spring body in the diameter-expanded shaft portion of the shaft body of the ratchet body, and the ring body of the ratchet ring. A ball holding hole for inserting / removing a positioning ball for fixing the ring body in a clockwise position, a counterclockwise position, and a neutral position through a spring body through a spring body; The ratchet ring is formed with a screw hole for detachably fixing the ratchet bit holder. The ratchet bit holder includes a fitting groove for positioning the ratchet ring and a ratchet claw holding long groove for holding the ratchet claw in a clockwise position or a counterclockwise position, and the ratchet bit holder holds the ratchet claw on the right side. Forming the gear part for fixing to the turning position, the counterclockwise turning position and the neutral position, and the hole part to be inserted into and removed from the threaded hole of the shaft body of the ratchet body. It is characterized by comprising.
