TWI235096B - Swiveling structure for wrench - Google Patents

Abstract

The present invention discloses a swiveling structure for a wrench, which comprises a wrench end forming a fitting block. The fitting block forms serration along one side. A handle has an end forming a receiving cavity. The handle also forms a receiving chamber adjacent to the receiving cavity. The receiving chamber has a radial outer circumference communicating the receiving cavity and is for accommodating a control device. The control device comprises a control bar and a resilient element. The control bar is normally biased by the resilient element to cause serration of the control bar to engage the serration of the wrench end to limit swiveling of the wrench. When a user forcibly pushes the control bar inward, the serration of the control bar disengages from the serration of the wrench end, which allows the wrench end to freely rotate and thus realizing control of swiveling of the wrench end.

Description

1 ^ 35096 V. Description of the invention (1) The present invention relates to a control part of a triggering part, which is coupled with a variety of industries, so that the market sees it). When the triggering part is provided with a spring and a latching part, The card can be used as an environmental view), and its upper ring is set. At present, the domestic accessories or the accessories that have been changed in recent years are mainly related to the department and the grip control department. The technical field to which the toothed pattern belongs is related to a "扨 and the holding part can be relative to the moving structure", especially the closing part can prevent the wrench / angle rotation ㈣, and has no need to rotate Time-shaking person [Previous technology] The public has hand-made cloths. The DI of the tool development department has been DI: the atmosphere is prosperous, the quality of the structure, t won the domestic J two middle school: 1 produced in order to make a jealous, and ancient moon hand tools. No. 6 2 1 6 5 6 7 holding part can be used for operation or with a humanized function; = a pivot part is formed between the parts, -b W is rotated by an angle, and the work is performed near the pivot part ~ The system includes a latch, a control button, and two evils. 'Control is pushed by the elastic force of the spring, forcing W to make the trigger part unable to turn, and when the control button is pressed and then pressed by the control button, it can be retracted inward. At this time, the trigger is reached to adjust the wrench. In order to respond to different conditions, two (Annex II is US Patent No. 6 1 4 8 6 9 8) two sets of socket blocks are formed on one end of the wrench part of the wrench, and the socket blocks are pivoted by the socket blocks. The triggering part is pivoted on the holding part

l235〇96 V. The description of the invention above (2) And the holding control device, the fixed shaft and a screw are fixed in the accommodation hole, and the moving part rotates, this kind of failure: the conventional structure Each component is easy to roll off. 2. If the axial and internal diameters of the parts are different, and the control effect is matched, it is efficient. 3. The front side of the accessory car ’s large, ca n’t be pressed until it is not ergonomic. 4. Linkage between custom parts: -Receiving hole is placed near the trigger part to accommodate the control. The device system includes -control #, -elastic parts ... solid: combining the above four 7L pieces into a control device and setting and locking the control device with another screw to achieve the effect of limitation. The conventional wrench rotation structure cannot be avoided. There are many control device components lacking the manual rotation structure. The components of the control device are numerous and complicated, and most of the components are lost in a small cylindrical shape, which causes difficulties in assembly. i, or the product yield reduction control unit to accommodate the ⑨ wrench i, must be located in the # backhand near the pivot to set a radial chamber, and the front and rear sections of the chamber are 5; 5 Ge in the trigger At the t-end, a two-tooth pattern rod and a two-tooth pattern on the fixed shaft are used to limit the rotation of the triggering part, which will make the production of the wrench more difficult. When you want to press the control button, the control button set on the front and learn the design, so that the user ’s thumb must move a small corner button, or even press the button with another finger, such as S Shish, It is bound to be difficult to win the favor of consumers. The locking method of the control part of the wrench rotation structure needs to be binary combination, so the locking effect is more unstable, and the more components are produced,

The probability of failure is high, so I will use "."-The final product! It is necessary to improve it. 疋 It is not practical, it is the main purpose of the invention: It is to provide a kind of wrench rotation structure, so I. "The wrench rotation structure used for the control part is complicated and difficult to assemble, 1: it is true and prone to failure. In order to achieve the foregoing invention, a set of sockets is formed at one end of the moving part. One of the sockets holds a tooth and a pattern, and a socket socket is formed at the -end of the grip, and the socket System i = An accommodating space is formed near the socket groove. The diameter of the accommodating space is connected to the socket and can be accommodated by a control device. The control equipment = a control rod and an elastic member. In the normal state, the control rod is pushed, and the tooth pattern of the control rod and the tooth pattern of the triggering part are made by the Karma: the triggering part cannot rotate, and the user presses the control rod into = The tooth pattern is disengaged from the tooth pattern of the triggering part, and at this time, the triggering part can be freely controlled: ί As can be seen, 'the rotating structure of the wrench of the present invention can be achieved only by using -press :: and the elastic member. The control of the rotation of the triggering part can eliminate the complicated lack of J two elements, and only one or two steps need to be detailed on the holding part when assembling; The rmc backhand can improve the yield of the finished product in manufacturing, and the advantages are reduced, and the production cost is reduced, and it is not prone to failure. To improve the competitiveness of the market and gain the user's favor. [Embodiment] _ Page 7 1235096 Figure 1. Please refer to the structure of the hand ^ ^ & ONE!
