Creation Instructions (i) [Technical Field to which the New Type belongs] This creation is to provide an easy-to-manufacture method; operate the control direction with the toggle, and read the direction control device of the wrench. [Prior art] At present, the ratchet wrench is provided with a direction control device for changing the direction, and the direction control block is used to control the direction of the control, which is described as follows: 1 · Double-block control direction of the card. Please refer to No. 90220645 In the case of asymmetrical teeth, the wrench body 1 is provided with a slot 3, and the ratchet wheel 5 is placed in the first receiving block 6 in the second receiving slot 3, and a shaft 8 at one end thereof is used to make the latching tooth 7 and the ratchet 5 phase. The knob 9 is clicked, while the outer side is provided with 9 transmission directions when the push block 6 is released from the ratchet operation; however, the latching tooth 7 of the 6 is in phase with the ratchet 5 and the resistance direction of the oscillating drive is straight up, making the dial block 6 reported capacity $ for torque, and the spanner's stomach 1 dial 6 and the production and processing of the second bomb Xin 1 is cumbersome ', and the large towel I has been processed and assembled, and can make the latch block to the lift latch drive The effect of the ratcheting force direction and the angle of the adjusting force are divided into a single card control direction and a double 1 as shown in the figure, which is the Taiwanese patented ratchet wrench adjustment block. The patent has the first receiving slot 2 and Two pivoting grooves 4 are provided on the wall surface of the second accommodation. One of the grooves 2 is provided with two latching teeth 7 which are placed in the pivoting grooves 4 for positioning. In addition, a spring 10 is provided between the two adjusting blocks 6, and the dial wheel 5 'can be used to control the trigger and the body 1'. The control split is only engaged by one adjusting block, which not only has a small number of meshing teeth, but Acts on the deflection strength of the rotating shaft 8 of the adjusting block 6, and reduces the operation of the wrench. Two pivoting slots 4 are provided for positioning and adjusting 0 to prevent arbitrary displacement, which increases manufacturing costs. 2 M247352 Creative instructions (2) • Single card control direction: Please refer to the figure 2 ^, 91 20 1915 "The structure of ratchet wrench is improved = It is specially designed for Taiwan Zhuohe body 1 1 with a first receiving slot丄 2 1 -Benefits, the wrench and a hole accommodating slot 1 3 spring 15 and steel ball 1 6 on the wall surface of the second accommodating slot 1 3, one with a latch to remove 1 4 for installation and placement in the second In the accommodating slot 13, the two latches ^ the latch blocks 17, 16 are placed on top, and the turntable 18 is used to control the fork steel balls 19 under the 7 for the wrench body 11 to apply a force to the 1 offset. Although the resistance of the engaging ratchet drive has been pushed up by the second receiving slot 1 1 2, the latch block 17 2 does not damage the strength of the latch block 17; side: the slot wall is used to match the number of teeth, but the turntable 1 8 The control block is not included, and can be increased. Because the block 17 and the ratchet 9 are both offset A 1 7 is shifting: the ratchet 19 're-enables the block to press the steel and must move'. When controlling the direction, not only the resistance of Yuan Zhu 16 is shifted but the resistance of the ratchet 19 is shifted, which results in the control of the second direction and the control of the direction must be achieved. In addition, the drilling tool cannot be used and is inconvenient and cannot be accommodated only in the second place. Slot 3 on ^: 1 drilling The processing is easy, and the steel balls 1 6 钭 62, D are drilled. Not only the processing does not "tilt, but only partially uses the 2 card engine block" to make the card engine card engine block ": car :: ratchet 19.
