Description

M247350 V. Creation instructions (l) [I. New type of technical field] The oblique f f belongs to the technical field of a ratchet wrench, especially refers to a kind of ratchet wrench. Eight buckle ... structures and suits, improved wheel picker tools and improved lever structure. [Second technology], a ratchet wrench and ratchet block can be used as a two-way ratchet wrench for inspection or screwing. It can be turned repeatedly when the wrench is removed. It can be seen that i. The efficiency of the pulling operation. According to the prior art, θ Α ^ The ratchet wrench tool mainly uses the "Pushing two excellent: the direction of the locking of the tooth block and the ratchet gear" exposed on it. Therefore, the setting of the toggle lever ^ —The function that affects the operation of the ratchet wrench. The patent creation of "thorn: ί (No. -1) which is the Announcement No. 4 0 8 6 5 3 Yigu 2)" (hereinafter referred to as "conventional creation"): t ί Most ratchet wrench tools are used to control ratchets The structure of the tooth block and the ratchet " 30 directional movement is as shown in the figure, that is, the first, second, and third accommodating parts must be provided at one end of the structural design for the opposite body to divide 9 1 ( Ratchet wheel), card engine 9 2 (ratchet block) and ^ 幵 3 9 3 (toggle lever), where the reversing switch 9 3 is connected with: 2 latching device 94 1 is inserted into it, and The above-mentioned combined structure and the 佶 i ^ top engine device 9 4 is arranged in a direction parallel to the handle portion of the board, and the Q ^ 4 end is inserted into the reversing switch 9 3 'and the other end abuts the latch f Making system = 9 2 1 slots on the outer side, so the "assembly space" required for the reversing switches 9 3 and 9 4 is relatively increased. In this way, the cost of processing is not high, and for small Ratchet wrench

For M247350, the structure is further used. The other 9 4 is pushed and the device 9 4 is purely closed 9 3 and moved. The top latching device 9 is stabilized by the collision and friction of the 9 9. The 4 is stable in movement and the direction is good. In view of this manufacturing experience, the needle was trial-produced according to the aforementioned needs, and finally became a structural improvement. ”[Chapter 3, the creative structure of the creative master ’s structure] The ratchet gear fits into a small space and uses space. In order to reach and affect the structure of the lever structure step, change its use with the ratchet system through the use of the latch 9 4 when it is turned over, 'affected ratchet characterization, so the action is stable' the creator The creative use of the above practice to actively seek solutions is to improve the appearance. The main purpose is to 'steer the direction of the ratchet system to save the space for setting up the ratchet. When the card's actuator 9 1 is “tough 2 Therefore, it is not only necessary, but also easy to communicate with the ratchet. The limited lever structure is based on the decision of multiple creatives. This creative study provides a round wrench lever and a wrench. 9 2 When receiving the direction of the & force ' pull the reversing switch 9 The turning force is better than the ratcheting part 9 1 and the assembly space becomes the improvement of the effect and the purpose of the industry's thinking. The top stopper device, the top stopper and the reversing opening 3 are driving large, and the improper top stopper device is installed and improved. In the years of research and development and related issues in related industries, it has been deeply discussed, and after 'long-term Research and lack of force "ratchet wrench tools of Ji Qi lever. "The ratchet wrench tool and its dial are used to push and change the ratchet block and structure, and can be reliably and reliably assembled in the manufacturing process and assembly process." This creation "ratchet wrench tool wrench body, ratchet gear, ratchet teeth

M247350 V. Creation instructions (3) Block and lever, where the lever is provided with an inner peripheral surface for receiving one end of the ratchet handle and adjacent to the inner edge of the lever. L, part, the outer end of which is a spring knot, and the other hook can be used to save the top part of the dial body, so that a well-implemented structure can be installed on the end The auxiliary end is used to set the sleeve end of the pole on the pole body, and the pole body is set on the lever to push the ratchet to the ratchet block. The structure of the wrench lever body again has a handle portion, and the volume is used for the capacity of the wheel to pass through a pair of its inner wall, the lever-type position shifting hole, the positioning portion, the sleeve positioning portion and It can be worn with a bounce, and a certain extension can be formed to form a certain positioning hole in the ratchet block and its space. When the moving block is pressed, the card brake section is changed. Method] Can be further explained later: 3 pictures ~ 6th improvement ", its body 1 〇 'and the corresponding one when the direction of the inward shrinkage, to the technology, explained in the placement section, the storage room, the surface is placed at the right end of the two ends, and the bullet can be set on the side of the toggle When the shift lever is changed, it releases the pressure and moves the stroke means back and deeper, and one end of the handle portion is adjacent to the ratchet block and an outward opening is provided to accommodate a lever body and the wrench is moved. The sex dial is in the dial, it should be turned outward, and it will be more stable when it is used. Its effect is based on the original body, and the positioning part on the end of the rod body that forms the rod can just be on the side. Protrude, and take this, not only to drive the sleeve of the elastic plunger to push the rattle to settle, smooth. Here is a better understanding of the above purpose. The structural design and technology of this creation are explained, as shown in the diagram, This creation "The ratchet wrench tool includes a ratchet body (10) and a ratchet gear (20) on the wrench body, a ratchet block M247350.
