Structure of wheel type positioning device

A structure of a wheel-type positioning device, comprising:

• a gun body having a hollow slot, a groove, a barrel and a guide slot, wherein one side of the hollow slot is additionally provided with a lead trajectory;
• a wheel disposed in the hollow slot of the gun body, wherein a surface of the wheel has a curved guide track, multiple front position-limiting slots and multiple rear position-limiting slots are additionally formed in the curved guide track, a front bump is disposed in each of the front position-limiting slots of the wheel, a rear bump is disposed in each of the rear position-limiting slots, and the wheel is provided with multiple receiving slots;
• and
• a grip portion, which is fit with the barrel of the gun body and connected with a linking rod and a rod body, wherein the linking rod is embedded into the guide slot of the gun body, a limiter is additionally disposed on the linking rod, the limiter is embedded into the groove of the gun body, and the limiter is disposed in the curved guide track of the wheel;
• wherein bullets are firstly placed into the receiving slots of the wheel through the lead trajectory on the gun body, and the receiving slots of the wheel can sequentially correspond to the barrel to complete loading actions through frontward and rearward reciprocating displacement actions of the grip portion, and the linking rod of the grip portion drives the limiter thereon to rotate the wheel, wherein the limiter can sequentially move to a next one of the front position-limiting slots or the rear position-limiting slots mainly through resisting and restriction of the front bumps disposed in the front position-limiting slots, and the rear humps disposed in the rear position-limiting slots, wherein provisions of the front humps and the rear bumps can prevent the limiter from moving and returning to a previous position, so that the wheel rotates in a same direction.
