The screwdrivers assembled according to the above components have the following advantages. - The short rods move with the starting element, and the wear rate of the tool heads is higher than that of the US 7,458'296 patent with the elastic arm collision and the hard wear rate. Less, so the replacement tool head will be smoother. Second, the short rod and the curved groove of the jade head cooperate with each other, and no additional production equipment is required, so the production cost of the creation is low. In addition, the base further includes two convex portions, and the oblique sides are formed on both sides of the convex portion. The starting element further comprises two elastic components, and each of the springs 4 M375 584 components has two inclined faces that contact the bevel of the convex portion. As the starting element is pressed, each of the elastic components accumulates the power required for resetting. With regard to the techniques, means and functions of the present invention, a preferred embodiment is described in detail with reference to the drawings, and it is believed that the above objects, structures and features of the present invention can be obtained from an in-depth and specific understanding. . [Embodiment] Hereinafter, the related embodiments will be described in detail based on the drawings. Figures 1 to 3 show a screwdriver 100 comprising a grip 1 〇, a tool head 11 and a clamping mechanism 2 〇 which is mounted on the grip 10 to replace the required tool head 丨j . In the drawing, the holding mechanism 2 is composed of two short rods 21, a base 30 and an actuating element 5''. Wherein, the base 3 includes a surface of the joint portion 31 which is uneven, and is positioned inside the grip 1 and does not rotate; a pivot portion 32 of a polygonal body and the joint portion 31 are formed into a body; a receiving groove 33, The spring portion 22 and the joint portion 31 are trapped and the spring 22 is positioned; the second hole 34, which is symmetric and the short rod 21 is worn, penetrates through the wall surface of the hinge portion 32, and the lower step portion communicates with the receiving groove 33. The two convex portions 35 are symmetrically formed along the lengthwise direction of the susceptor at the opening of the hinge portion 32, and each of the convex portions is formed with a beveled edge 36; a ring piece 37 whose inner surface is connected to the two convex portions The surface of the joint section 3 i of the H plane exhibits an uneven state due to a plurality of strips (not numbered), and fits into a groove (not edge) of the same shape that is caught in the grip 1 , so the joint section 31 5 M375584 and the grip The ίο will not rotate between each other, and the two can only work together. Secondly, the surface of the joining section 31 is not limited to the uneven shape. It may be a keyed shape, a non-circular shape or another shape in which the grip is combined but not rotated. As for the shape of the pivot section 32, not limited to a polygon, such as a circular shape, a non-circular shape or a polygonal shape, the activation element 50 may include a pressing piece 51, and is provided at a central position - in a penetrating shape. Inserting a hole 52; two supporting f 53, extending symmetrically along the insertion hole 52 in the axial direction and extending symmetrically to the pressing piece 51, each of the supporting arm brothers passing the gap between the two convex portions 35 and the inner surface of the ring piece 37, and pasting The hinge portion 32 of the seat 30 is externally formed, and a recess 54 is formed at the edge for the end of the short rod. By enclosing the side of the periphery of the recess portion 54, 57' restricts and drives the short rod 21 along with The support arm 53 is actuated; an elastic member 55, each of the elastic members 55 is axially extended along the insertion hole 52 to form a split shape, and a bevel 56 having a convex portion % is formed at the end portion. The pressing piece is a ring body, and its edge may be a non-circular edge, such as a polygonal side, a polygon, or the like, in addition to the circular side shown in the drawing. As for the depressed portion 54, in addition to the oblique opening, Hxf perforations or grooves and other functional impurities. As shown in Fig. 45, each of the elastic members 55 touches the oblique side 36 of the convex portion 35 with two inclined faces 2 to support the starting member 50 to the base 30. At this moment, the short rod 21 is driven by the support arm 53 to clamp the portion where the white hole 34 communicates with the receiving groove 33, and restricts the starting member 50 from being separated from the base 3. _Reviewing the first picture 'The tool head 11 is inserted into the clamping mechanism 20 of the screwdriver (10) in the following two ways: 6 factory, ί a replacement method 'Please look at 帛 2, 6 to 8 ®. The pressing piece 51 of the shoe 50 is actuated to displace the supporting arm 53, and the same as the 'short bar 21 is moved to the position of the groove 33 by the recessed portion 54 to be inserted into the hole 52 through the pressing piece 51. The work head Η 'goes deep into the accommodating groove 33 of the susceptor 30 and squeezes the external force applied to the pressing piece 51 to release the starting element 50 to the original shape' and the short rod 21 returns to the stepped hole with the recessed portion 54. % is connected to the portion of the groove f, and locks the arcuate groove of the tool head u. Pressing the pressing piece 51' again causes the short rod 21 to move away from the position where the step hole 34 communicates with the accommodating groove 33, so that the tool head u can be pulled away from the holding mechanism, and the second replacement mode is compared (4). The tool head 10 is directly inserted into the insertion hole 52 of the pressing piece 51. At this moment, the two short rods are in contact with the end portion of the tool head u at the portion where the stepped hole 34 is located, and the position of the position of the hole 34 is not communicated with the receiving groove 33. The tool head 1 which is not hindered by the short bar continues to penetrate the receiving groove 33 and presses the spring 22' until the time when the curved groove 12 faces the step hole 34. As for the short rod 21' in the displacement state, the side wall 57 of the recess 54 is pushed so that the 2 arm 53 interlocks the pressing piece 51 to move in the same direction, and at the moment when the curved ΐ 12 faces the step hole 34, because the starting element 5 The reason why the self-recovery of the original shape causes the short rod 21 to be reset to fall into the surface of the curved groove 12, and the clamping mechanism 2 locks the tool head u. The power for the reset element 50 to be reset is derived from the resilient assembly 55. When the pressing piece 51 is pressed down, the two inclined faces 56 are guided along the oblique side %: the convex portion 35 is opened by the elastic member 55. At the moment, lose the short stick? ! The restrained tool head η can be ejected toward the insertion hole 52' by the force accumulated by the spring 22, and the tool head u can be extracted without difficulty. Then, when the external force of the M375 584 pressing and holding the pressing piece 51 disappears, the stretched elastic member 55 returns to the guidance of the oblique side 36 to return the starting element 5 to the original state, and waits for the execution of the next pressing operation.
除此之外’本貫細例的元件或構造，還能演變出 一些變化。在第9圖中’圓形短棒21的端部設有一 外擴部60，而凹陷部54的外圍則陷入一呈階級狀的 承接槽61。§玄外擴部6 0的直控，大於凹陷部5 4的 口徑’但比承接槽61的口控還小，對於組裝方面具 備更優異的效果。譬如：外擴部6〇抵觸承接槽61的 壁面，導致短棒21不易穿過凹陷部54、位階孔而掉 落。In addition to this, the components or constructions of the detailed examples can be changed. In Fig. 9, the end portion of the circular short rod 21 is provided with an outer expansion portion 60, and the outer periphery of the concave portion 54 is caught in a frame-like receiving groove 61. § The direct control of the outer expansion portion 60 is larger than the diameter ' of the recess portion 5 4 but smaller than the mouth control of the receiving groove 61, and has an excellent effect on assembly. For example, the flared portion 6〇 abuts against the wall surface of the receiving groove 61, so that the short bar 21 does not easily fall through the recessed portion 54 and the stepped hole.
