Description of the invention (/) The present invention is a ratchet tool with a multi-angle change pawl. Its main purpose is to greatly reduce the idling of the dry wheel when creating a wheel training tool that does not operate forward or reverse. To facilitate the use in narrow or special occasions. It is to set the engine strands on both sides or both sides, so that the tooth-shaped part of the double-layered detent intersects with B and reduces the distance between any two adjacent teeth to make the wheel turn. Those who can engage with any of the detents to achieve the above-mentioned purpose. According to the current ratchet tool, it is extremely popular, because the dry wheel tool can be set to rotate in one direction, while the other direction is only idling. Reverse the actuating head or sleeve that fits with the workpiece, so if the coupling or loosening of a bolt is limited in a limited space, the author does not need to use a military pure wrench, but must survey at a certain angle After that, lift the wrench out of the yoke bolt, and then turn the wrench back to the original position, and then fit it on the yoke bolt. Repeat the last few times to tighten or loosen a bolt. Printed by the Shellfish Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page). If the space available for rotation is small, the number of above-mentioned action cycles will be more. Because the direction of effective movement of the sleeve (for example) can be limited, the author does not need to move the tool away from the workpiece after rotating at an angle, but can directly reverse the rotation to the starting position and then rotate, and the reverse rotation action sleeve They do not turn, so the cabinet saves time and difficulty in operation. The same effect is achieved by using a ratchet and a ratchet catch. Generally, the catch is pivoted on the tool base and It has two tooth-shaped parts, and the author can use the pattern linked with the pawl to set the direction in which the tooth-shaped part will be combined with the runner. However, in the process of the work, because The training tool must have a certain torque wheel—3 — This paper size is applicable to the Chinese National Standard (CNS) Α4 size (210X297 mm) 83. 3.! 0,00 The staff of the Central Government Standards Bureau of the Ministry of Economic Affairs consumes Cooperation Du printed 404879 V. Description of the invention (the), therefore, the tooth shape of the toothed part of the reel and the pawl must have a certain depth and strength. In contrast to the chiseled part, between the teeth of the two phases There is a certain degree of difficulty, and the ballast distance causes the idling of the tool. The idling phenomenon does not disappear until the dry wheel is actually fitted with a tooth of the catch. The road-like phenomenon can be accepted in general use situations, because the space for the tool handle to rotate is still shackled, but if the ratchet tool is operated in a very small space, it will be buried, and when the idling distance is controlled by the handle After the parts are moved, and the teeth of the pawl mesh with the ratchet, the remaining operating space may be lost by more than half of the way. The situation makes the effective turning space or the turning angle relatively small, which makes the stern wheel tool "The work efficiency is greatly reduced." If in order to improve this phenomenon, the density of the number of teeth of the catch is increased to reduce the distance between the two a parts of the orange part *, the torque that the fine toothed part can withstand will be too small. Those who do not meet the work requirements of ratcheting tools that require higher torque "The inventor was here to improve the above phenomenon, and developed a spicy wheel with a multi-angle automatic switching engine that meets the above conditions The tool is mainly provided with a pawl located on both sides or making the two pawls more than a pair of tadpoles and staggered angles, so that the tooth-shaped portion of the Huazi is arranged in a staggered manner * When the detent is coupled with the ratchet, any one of the detents on both sides can be combined with the ratchet to reduce the idling distance by at least half compared to the user. The less the chance of idling, it can be described as an alternative stepless switch tool installer.

When using the 赅 ratchet tool, the operator selects a certain direction as the effective direction of the rotary joint (2 1) by the dial instrument. At this time, Detent (33), ( 30 is pivoted at the same time so that a protruding end of the same position of the two detents (33) or (34) protrudes into the perforated (12) fan garden and can be engaged with the tooth surface.

If the angles are staggered, the thickness of the tooth surface should be designed to exceed the thickness of any one of the latches (33) / (34). It is the sum of the thickness of the two pawls, and the tooth surface can be combined at a smaller angle when rotating. Therefore, if you can change the angle of the dry wheel tool device in steps, the creation can also be implemented on a ratchet.

As described in the third to fourth circles, because the latching elements <) located at the two are not at the same time, "the angle setter" can be rotated by a small angle to make the force act, that is, the single element (80 > / (81) is a combination of the tooth surface (42) provided in the handle at a different angle at the same time to facilitate the user's force. Similarly, the holding element < 80 > / (81 & gt The number of layers can be set in the vertical space, which is the same as that of the top fi element (53) / (54). It can also be set with the same number. In the meantime, the rotation angle can be set with the number and the opposite direction. Multiplied by Miles Low, "It can achieve the effect of the so-called stepless switching angle-9 --- This paper size is suitable for Chinese poor families (CNS > A4 size (210X297 mm) 83.3.10,000 -------- r Install ----- ^ I subscribe ------- " (Please read the precautions on the back before filling out this page) 404879 A7 ___B7 V. Description of the invention (, ξ). To sum up, the present invention uses a pair of pawls and pawl elements that are arranged oppositely or stacked on the opposite side, and the teeth of the pawl and pawl elements are not set at the same time. The staggered arrangement can reduce the space between the teeth of any two phases, and greatly reduce the idling angle and distance when operating the infusion tool, which effectively improves the defects of the conventional reel tool. Those who are not used in all kinds of dry wheel tool structure, it is truly unseen, and its high cutting performance has surpassed the conventional known structure, the structure of this device has excellent usability and efficiency. The ratchet tool that has been used generally exceeds the requirements for a profit application, and I love to apply in accordance with the law. ------- 'ί Outfit ----- ^ — Order ------'- d.
