然，睛參閱第七圖及第八圖所示，此種習用之十字形 起子頭無法避免的會有以下缺失： 1 、因一般人家中並不具備有全規格尺寸之十字螺絲 巳子，故在使用上，螺固工件之十字孔往往會大於十字螺 絲起子之起子頭’若起子頭無法與螺固工件十字孔完全貼However, referring to Figures 7 and 8, as shown in Figure 7, the conventional cruciform screwdriver head will inevitably have the following defects: 1. Since most people do not have Phillips screwdrivers with full specifications, In use, the cross hole of the screwed workpiece is often larger than the screwdriver head of the Phillips screwdriver.

Zhu Yu: ΐ = Step-by-step creation, which is worthy of the industry to come M251696 IV. Creation instructions (3) [Implementation mode] This creation is about an improved structure of a screwdriver head, please refer to the first to third pictures, The improved structure of the screwdriver head mainly includes a screwdriver (1), and one end of the screwdriver (1) is a holding portion (1 3) for a user to hold, and the front end of the holding portion (1 3) A shaft (14) is inherently inserted, and a cross-shaped screwdriver head (1 0) is formed at the front end of the shaft (14). The screwdriver head (1 0) is composed of four flaps (1 1), and A straight wave-shaped convex tooth portion (1 2) is formed on both sides of the front end stopper (1 1) of the screwdriver head (1 0), and the convex tooth portion (1 2) is used to increase the screw head (1 0). It is used for the contact area with the cross hole of the screwed workpiece. For the usage status of this creation, please refer to the fourth to sixth figures. When you want to turn and unscrew the screwed workpiece (20), insert the screwdriver head (1 0) into the screwed workpiece (20). In the cross hole (2 1), if the cross hole (21) is slightly larger than the screwdriver head (10), the catch (1 1) of the screwdriver head (10) cannot be connected with the cross hole (2) of the screwed workpiece (2 0). 1) Completely fit, at this time, since the convex parts (1 2) of straight waves are formed on both sides of the detent (1 1), the convex parts (1 2) can be added and screwed. The contact and engaging area of the cross hole (2 1) of the workpiece (2 0); in this way, the turning force of the screwdriver head (1 0) on the cross hole (2 1) can be dispersed to the hole of the cross hole (2 1). Throughout the wall, the screwed workpiece (2 0) will not collapse due to the contact area being too small and the force is too concentrated, which will cause the cross hole (2 1) to collapse, and even the lock can not be turned. Fixing interference; and the convex tooth part (1 2) on the catch (1 1) can also increase the friction between the screwdriver head (10) and the cross hole (2 1) of the screwed workpiece (20), so that
