(2) For the structure of this patent, please refer to the description of the first figure: The ratchet wrench in L is mainly composed of the wrench body 6G and a ratchet wheel 70. A moving block 80 and a spring 90 are arranged, and the cymbal 9 is installed in the swaying block 8 H ” H H 及 及 及 及 及 及 及 及 及 及 及 及 及 及 丝 丝 丝 丝 丝 丝 丝 丝 丝 丝 丝 丝 丝 丝 丝 丝The depth of the slot 61 & 81 cannot unify the problem of -4- 20 M311536, and the spring 90 is designed in the shape of a sapphire, that is, the aperture of the spring 90 is gradually reduced from the middle to the two ends; thereby, when the spring 9〇 When the two ends are respectively disposed in the two slots 61 & 81, the middle portion of the spring 90 can be engaged with the outer edge of the two slots 61 & 81, and the two ends of the spring 90 do not need to be connected to the two slots The bottom of the holes 61 & 81, so it is not affected by the deep production of the two slots 61 & 81. Moreover, the design of the magazine of the above-mentioned shackles can improve the problem of different depths of the slots. However, the aperture system of the intermediate body to the two ends of the spring 9 逐渐 gradually becomes smaller, and when the hand is subjected to a large torque, the middle section of the magazine 9G It will be twisted and the part will gradually be forced by the three slots 6_, which will change the length of the change direction and the elastic force. The torque of the front wheel wrench is also changed and the improvement effect is still not improved and still needs to be improved. [New content] 15 20 hand, the ratchet wrench of the material 'reverse:::: accommodate: provide a kind of fixed elastic ratchet wrench wheel; The part is provided with a capacitance 6: a body having a receiving portion at the end of the body, and a receiving hole of the wrench body; the pulling member is disposed at the portion, so that the pulling member is only the plate member The ratchet is rotated, and a spring is mounted -5- M311536. The tilting block is closed with the groove of the hand body, and the aperture of the middle body is larger than the two ends of the spring. [Embodiment] In order to understand more The detailed construction and function of the present invention, the preferred embodiment and the following description, wherein: the second figure of the undercarriage is an exploded view of the preferred embodiment of the present invention; 10 the third embodiment is a preferred embodiment of the present creation The combined perspective view; the fourth figure is a cross-sectional view along the 4_4 section line in the third figure; and the fifth figure is a perspective view of the magazine of the present creation. First, please refer to the second to fourth figures. The ratchet wrench with fixed elasticity includes a wrench body 10, a trigger member 2〇, a swaying block 15 and a spring 40, wherein: the wrench The main body 10 is generally of a long rod type, and has a receiving portion 11 at one end thereof. The inner side wall of the receiving portion 11 is recessed inwardly with a receiving chamber 12, and the chamber 12 is recessed with a predetermined depth groove at a predetermined position. The hole 13 and the outlet end edge of the slot 13 form an abutting surface 14 , and the wrench body 1 further includes a 2 〇 buckle 15 and a ring cover 16 for the receiving portion of the wrench body 10 After the remaining components are installed and fixedly combined, the assembled structure of the wrench body 10 is a well-known technique, and is not described herein. The triggering member 20 is formed in a cylindrical body, and is pivotally disposed in the receiving portion 11 of the wrench body. The outer peripheral ring of the triggering member 20 is provided with a ratchet shape. -6- M311536 == part: Γΐ Item 2. A polygonal hole 22 is provided in the center for a screw or a nut to accommodate the cassette. The swaying block 30 is installed in the chamber 12 of the wrench body 1b, and has a ratchet portion 3 of the mine, and the ratchet portion 21 of the trigger member 20 is ready for the heart. Rotating in a single direction, if the pulling is made, the triggering member 20 can only rotate along the 3棘 ratchet portion and the plate member 2 to rotate the '(4) moving block without practicing the movement 1掣=t will produce Na The manual block 30 is recessed inwardly at a predetermined portion by a 10 15 -slot 32, and the exit end edge of the slot 32 forms an abutment surface 33. The spring 40 is mounted on the secret 32 of the operating block 3Q, and accommodates the valley chamber 12 of the two-wrench body 1G. The magazine 4 () has a rod-shaped stick shape, and the end is short and the middle section is large. Wherein, as shown in the fifth figure, the elastic cyanine 4 〇 = middle & forming body 41 ' is larger than the slot 13 of the chamber 12 and the slot 32 of the upper block 30, and The two ends of the spring 4 are respectively provided with a small hole 13 & 32, a small one of the first fitting portion 42 and a second fitting P 44 ' and the forming portion 42 and the body portion 41 are formed. a first abutting surface 43, a second abutting surface 45 is formed between the second engaging portion 44 and the body portion 4, and the fourth figure is further viewed by the member, when the magazine is The first engaging portion 42 of the spring 40 is embedded in the slot 32 of the ram block 30, and the first pressing surface 43 is coupled to the swaying block 30. When the second engaging portion 44 is inserted into the slot 13 of the chamber 12, the second pressing surface 45 is abutted against the receiving surface 14 of the wrench body 1 . The spring 40 is abutted against the abutting surface 33 of the ram block 30 M311536 by the first pressing surface 43 , and the second pressing surface 45 is coupled to the yoke surface 14 of the wrench body 1 . The first and second fitting portions 42 & 44 are not connected to the bottom of the two slots 13 & 32, and are not affected by the depth of the two slots 13 & 32 15 41 is directly falling from the apertures of the first and second fitting portions 42 & 44, and the body portion 41 < the aperture is larger than the aperture of the two slots 13 & 32 ▲, so the spring 4〇 does not cause Tolerate the torsion force ί ^ The body Γ 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 41 The axial length of the body 4 of the body 41 can be controlled to be a fixed number of laps, gentleman, and the green money on the green seat will be maintained at 3 〇. Further, as shown in the above-mentioned lifting block, the body 41 of the original fixing spring 40 and the first ratchet wrench are hunted by the aperture of the magazine-Ά » 5 ^ 42 & 44 The direct gun yellow 4〇 provides a fixed elastic force. ^Sec.1, the above mentioned, only the HI of the creation of this HI is the torment of the board. It is more than a sloppy application. Therefore, the general round of the hand should be included in the special plane of this scale. 4 (4) Structure, -8- M311536 [Simplified Schematic] The first figure is a schematic cross-sectional view of a conventional ratchet wrench.
