The present invention relates to a screwdriver bit storage structure, and particularly refers to a screwdriver bit elevator.

Generally, when the screwdriver bits are stored or displayed for sale, an elevator is used to combine the screwdriver bits. The elevator is placed on the wall or display board for users to pick up and use or for consumers to select and inspect.

Referring to Figure 1, the screwdriver head is shown in the state of a conventional elevator. The elevator 11 mainly restricts the connecting portion 121 of the screwdriver head 12 through the limiting groove portion 111, and then locks the screwdriver head 12 into a customized position through the locking groove portion 112. The marking portion 122 of the screwdriver head 12 is used to limit and position the screwdriver head 12 on the elevator 11. However, it still has the following defects that need to be improved immediately in actual use:

First, at present, the joint portion 121 and the marking portion 122 of most screwdriver bits 12 are hexagonal in cross-section, so that they can be clamped and driven by the driving tool (not shown in the figure). At the same time, the marking portion 122 of the screwdriver bit 12 is processed. (such as laser processing) has model or specification text that is common in the industry or listed by the manufacturer. Therefore, when the screwdriver head 12 is placed behind the elevator 11, is the model or specification text clearly displayed for the user to take or consume? It is extremely important for buyers to choose and buy. However, the conventional elevator 11 uses two opposite groove wall surfaces 1111 of its limiting groove portion 111 to limit the two opposite side planes 1211 of the connecting portion 121 of the driver head 12. Therefore, the driver head 12 is disposed on the elevator 11 Finally, the ridge line 1212 connecting the adjacent two side planes 1211 of the screwdriver head 12 is exposed to the outside.

Therefore, the model or specification text on the side plane 1211 of the screwdriver head 12 is It must be processed in advance and cannot be assembled on the elevator 11 for one-time processing. When the screwdriver head 12 is processed with model or specification text in advance, a special jig (not shown in the figure) must be prepared and made. Use this jig. Each screwdriver head 12 is fixed with a tool, and then the model or specification text can be processed, which highlights the disadvantage of high processing cost; at the same time, when the screwdriver head 12 has the model or specification text processed and is placed on the elevator 11, it still has the directionality of setting. restrictions to prevent the model or specification text from being completely obscured, highlighting the disadvantages of labor-intensive setup.

Third, since the conventional elevator 11 restricts the coupling portion 121 of the driver head 12 through the limiting groove portion 111, and then locks and positions the marking portion 122 of the driver head 12 through the locking groove portion 112, therefore, when When the screwdriver head 12 is pulled so that the marking portion 122 is separated from the clamping groove 112 of the elevator 11 and the coupling portion 121 is still located in the limiting groove 111 of the elevator 11 and is in the display state, due to the limitation of the conventional elevator 11 The notch of the groove portion 111 is completely open. Therefore, when the screwdriver head 12 is turned to display, it is very easy to fall off the elevator 11, causing inconvenience in the display operation.
