The grip 11 has a flange m at the front end surface, a recessed hole 112, an elongated recessed hole 113, a groove 114, a hole 115, a positioning hole 116, and a positioning formed in the center of the flange 111. The groove 117 and an annular recessed groove 118 «Hai spring 17 and the ejector rod 18 are sequentially placed in the hole 115, and the spring 19 and the positioning steel ball 10 are sequentially placed in the positioning hole 116. The ratchet lever 2 passes through the recessed hole 112 and is connected to a sub-rod 100. The braking unit 13 has two long brake blocks 13m, two springs 132 placed on the back of the brake blocks 131 and the middle of the two ends of the long concave hole Π2, and the brake blocks 31 are placed in the long shape. The two ends of the concave hole 113 are provided with stepped concave teeth 1311 opposite to one side of the ratchet lever 12 for humming on the peripheral edge of the ratchet lever 12 so as not to rotate. The shift lever 14 has a τ-shaped upper end 14 ι placed above the ejector lever 18, and a lower end 142 bent down into the elongated recess 113 and located between M261336 of the two brake pads 131. The shift lever 14 It is possible that the ejector pin 17 is a fulcrum and has a left ancient deviation (see Fig. 3). The 该 button 16 疋 is in the shape of a cap, and is arranged on the flange U 1 of the handle 11, and has a dial 5 extending downward from a top wall and capable of suppressing the lever 14 丨 61, A recessed groove 162 formed on the inner side of the bottom edge of the wall, a notch 163 formed on the bottom edge of the wall, and a three-block block 165 formed on the top wall. The c-shaped buckle 15 is embedded in the recesses. The grooves 117 and 62 have an operating end 15m located at the opening and penetrating the gap M3. 10i as shown in Figure 1, Figure 2 and Figure 3, during operation, you can turn the knob 16 to change the position of the dial 161 pressed on the upper end 141 of the lever 14, when the dial 1: 1 pressed on the upper end 141 In the center, the two brake pads 131 are engaged with the ratchet lever / 2, and the ratchet lever 12 can be two-way linked with the grip 11. When the pad 161 is pressed against the -side of the upper end 141, the lower end 142 of the dial 14 A yaw, 15 further pushes it in—the brake pad 131 moves backwards, causing the ratchet lever 12 to idle in a direction that is not resisted. Although the conventional ratchet screwdriver can achieve the operation purpose, 'two-way linkage, or linkage in one direction and idling in the opposite direction, and the linkage direction can be switched in time', there are still many shortcomings: 20% 1. Insufficient binding force. · The ratchet teeth at the periphery of the ratchet lever 12 are in the axial ring. The convex teeth 1311 of the brake block 131 are also axially matched with it. When they are engaged, only the ratchet teeth are engaged with a convex tooth 1311. The contact area is quite limited, and the mouth force is obviously insufficient. As for the remaining ratchet teeth, it can only determine the length of the idling stroke. The king cannot increase the binding force. Once the resistance of the locked object is too large, the ratchet teeth M261336 or convex teeth 1311 will have material damage. However, this shortcoming is also a common problem in the market that various ratchets that use ratchets as latching devices are available. 5 10 15 The components are complex ... As can be seen from Figure 1, the flange 111 of the handle 11 must have β and asymmetrical holes or grooves to accommodate many small parts (except the ratchet buckle 12). Problems such as high difficulty, high cost, and time-consuming distribution during manufacturing are derived. [New content] Therefore, the object of the present invention is to provide a ratchet screwdriver with high bonding strength and simple components. The new ratchet screwdriver is provided with a base body fixed at the front end of the handle. The base body is inserted with a -driver #. The ratchet screwdriver includes the base body, -the first evil mover, -ratchet, -linked single elastic element and _ Turning pieces.

(See Figure 9, Head H), Figure 2 2 'When the driver ’s 100-bit position is turned in L County and the right turn is turned (see arrow 1 in Figure 4), the hips are used as the reference, so that the first, second "The second moving part 4« the second engaging part of the block ... 3 is displaced, at this time == the second engaging part 63 of the-and-, after being rotated, it is pushed upward by the tooth 55-so that The engaging portion 632m = 10 M261336 ίο 15 20 at the same time from the concave tooth portion 55, and is located above the ratchet tooth 54. Therefore, when turning clockwise or counterclockwise (see arrow V and arrow shell respectively in FIG. 9), the engaging portion 632 is no longer locked in the concave tooth portion 55. At this time, the elastic element 7 is slightly compressed by being pushed by the base portion 631, and the latching portion 622 of the first latching member 62 is restrained by the straight portion 432 and is still fixed in the concave tooth portion 55. Therefore, When the ratchet screwdriver is turned counterclockwise (see the arrow shell of Fig. 10), the engaging portion uses its tapered bevel 6221 to guide the climb to the next ratchet tooth 54, and passes through each concave tooth part 55 and each ratchet one by one. Tooth 54. Conversely, when the forward rotation = the ratchet driver (arrow V in FIG. 10), a vertical wall 6222 of one of the first engaging members 62 is blocked by the concave tooth portion 55, so the ratchet is rotated in the forward direction. The screwdriver can achieve the purpose of locking the screw. The ratchet screwdriver that rotates counterclockwise: As shown in Figure U, Figure 12, Figure 15, when the screwdriver lever 100 is positioned at a certain point, and the rotary member 8 is turned to the left (L) When turning (see arrow Π in FIG. 4), the first detent 4 is based on the block body 610, so that the first and second detent sections 43, 44 are I. The _ first engaging members 62 and 63 are displaced. At this time, the first engaging member 62 originally locked on the concave tooth portion 55 is rotated, and the base portion 621 thereof is replaced by the convex top portion 431 of the first engaging portion 43. Raise it upward so that the latching portion 622 and the tapered bevel 622 are simultaneously separated from the concave tooth portion 55 and are located above the ratchet tooth 54, so turn clockwise or: Turn clockwise (see arrow iv and arrow melon respectively in Figure 11), The engaging portion 622 is no longer locked in the concave tooth portion 55. At this time, the elastic element 7 is subject to the

Therefore, turn the ratchet screwdriver clockwise (see The arrow fork in Figure U), the clamping portion 63B 11 5 10 15 20 M261336 = its tapered inclined surface 6321 guides to climb to τ-ratchet 54, and each = two teeth: 55 and 54. Conversely, when the ratchet wheel is rotated in the reverse direction (the arrow ffl in FIG. 1!), The second engaging member blocks from the vertical niches to the concave tooth portion 55, so the reverse rotation of the ratchet driver can reach The purpose of loosening the screws. Through the above description, the new ratchet screwdriver does have the following many functions, which are summarized as follows: 1. Strong binding force: With the first and second clamping members 62 and 63, the first First, the configuration of the second latching sections 43 and 44 and the symmetrical ratchet teeth 54 and the concave tooth portion 55 makes the ratchet driver's engagement force stable and extremely strong when turning the ratchet driver. Second, the structure is simple: The combination of the first-detent element 4, the ratchet wheel 5, the linkage unit 6, and the elastic element 7 has not only the advantages of simple structure, but also each element has a corresponding slot or The convex portion is “easier to manufacture”, which can save the manufacturing assembly cost. It is worth mentioning that the arc-shaped protruding ratchet teeth 54 and the second stopper 61 make a circular-arc recessed front end surface, In addition to enhancing its stability, it also jumps out without finding gaps'. Therefore, In the present embodiment, although the embedded portion 611 of the block body 610 is made into a groove, and the fitting portion 642 of the assembly 64 is made in cooperation, The convex connection block, of course, can also be used to set the embedded portion 611 as a convex block, and the fitting portion can be made into a groove, which can also achieve the same combined effect. However, the above is only one of the new models. Only the best embodiment, when 12 M261336 can not be used to limit the scope of the implementation of the new model, that is, any simple equivalent changes and modifications made according to the scope of the patent application of the new model and the content of the new specification should still fall within the scope of this new patent [Brief description of the drawings] 5 10 15 20 Fig. 1 is an exploded perspective view illustrating a conventional ratchet driver; Fig. 2 is a top view; Fig. 3 is a cross-sectional view illustrating the operation of a shift lever to the left and right;
