Screwdriver with a function of accommodating a screwdriver

The present invention relates to a screwdriver, and more particularly to a screwdriver having a function of accommodating a screwdriver head for facilitating the use of a screwdriver.

The early screwdriver includes a handle and a rod. The handle is for the user to hold and apply a rotary screwdriver. The rod has two ends, one end of the rod is axially disposed on the handle, and the other of the rod One end corresponds to the groove of the bolt head to form a word, cross or other shaped working end. Since different bolts have different shapes and different sizes of grooves, the working end of the early screwdriver is directly formed on the rod. Body, therefore can not be applied to different types of bolt heads, users must prepare a number of screwdrivers with different working end of the work to match the bolts of various specifications, bringing users troubles in preparation and carrying.

In order to solve the inconvenience caused by the early screwdriver, the manufacturer has improved the early screwdriver, and the existing screwdriver shown in FIG. 9 includes: a plurality of screwdriver heads 50, a handle 60, a screw cover 70 and a rod. The handle 60 has two ends and is provided with a plurality of chambers 61 for receiving a plurality of screwdriver heads 50. The screw cap 70 is screwed to one end of the handle 60, and the rod body is axially disposed on the handle 60. At the other end, the rod body has an end away from the handle 60.
