New description: • ?月补补无 【New technical field of the invention】 This is a kind of telescopic wrench structure, especially a two-stage grip for adjusting the length of the telescopic wrench structure. [Prior Art] - Pressing the relevant open technology, such as Taiwan Patent No.: Μ344227 Telescopic Ratchet Wrench Control Set Limit Structure', its independent items include: • '祖接杆, the set of posts a hollow rod body having an opening at the front end thereof, and a sleeve for the front end of the body is provided with a control sleeve, and the side of the body is concavely provided with a sliding groove on the side of the long axis 2 The slot is provided with a plurality of positioning slots, and the set of the connecting rods is opposite to the control sleeve and has a positioning ring groove, and the positioning ring groove is provided with a -C-shaped buckle, and the set of connecting rods corresponds to the t-shaped - a positioning hole is arranged in the positioning slot, and a return spring is arranged in the control sleeve for pressing the return spring to the top of the C-shaped buckle when the control sleeve is adjusted. At this time, the positioning steel ball is separated from the The main purpose of the sleeve is to block the length of the body, and the main part of the body is: • the limiting portion is disposed on the outer wall of the open end of the gas block, and is formed with a plurality of outer 2 ring, For the hollow ring body, the inner ring wall corresponds to the inner ring of the limit ring, so that the limit ring can be _ The limiting portion acts on the limit of the control sleeve and is used to adjust the limit of the control sleeve to release the return spring against the limit ring, so that the control sleeve remains in the limit The position of the above structure is particularly important. Only 3 M366445 "·一—____ The structure still has a set of post and body fit, although in the set of posts, and set of reading m' in the body of the bribe to provide positioning steel ball accommodation limit However, because the chute provides the "face" to contact the positioning steel ball, and the positioning steel ball y "point" and Lai contact, 遂 in the mutual paste limit _ system, the positioning steel ball will have _ If the problem is too large, it will affect the shortcomings of the body. In view of this, the creators of this case have improved the mines in response to the above shortcomings, and have been diligently studying and constantly seeking new changes. Under the concept of perfecting and perfecting, after many trials and experiments, 'finally the county _ New Zealand patents in this case Application. [New content] The main purpose of this creation is to provide an inner and outer wrench in a nested relationship. When the length displacement is adjusted, a concave and convex indentation structure is specially designed to reduce the inner and outer wrenches. The gap between the inner and outer wrenches is such that when the length is extended or contracted, the telescopic wrench structure does not cause excessive looseness. In order to achieve the above purpose, the present invention provides a telescopic wrench structure, wherein the inner wrench of the bag has a plurality of concave rings arranged at a suitable interval, and a ratchet device at one end is provided with an external wrench, which is a hollow tube. The body is provided for the inner panel of the inner sleeve, and the end of the outer wrench is provided with an adjusting device, and the regulating device can be mutually restrained or independent from each other, and is characterized in that: The inner wrench is provided with a symmetrical convex portion on one side opposite to the outer side, and the outer wrench has a symmetrical concave portion along the long axis direction of the inner wall of the tube hole, which can be used for the position of the symmetrical convex portion, 4 M366445 and the displacement sliding of the length change . [Embodiment] For the rest, we will continue to cooperate with the diagram of the embodiment of this invention to explain the person who made the county into a visceral technique. Please refer to the first to fourth riding #, the preferred embodiment of the telescopic wrench structure for the sword, comprising: an inner wrench 10, one end set with a ratchet device 11 , the inner wrench 1 〇 in the t _ rod body It has a majority of concave ring 12 in the distance between the Qing and the body. It can be placed in the county 33 of the outer wrench 2G. An external wrench 20 is a hollow pipe body. The wrench 10 is sleeved, and the front end and the rear ring (4) and 22 are provided at the end spacing, and each of the front and rear ring grooves 21 and 22 has a front and a rear buckle 2U and 221, and the other is in front. A bead hole 23 penetrating through the wall of the outer wrench 20 is provided between the rear ring groove 2b22, and the top bead 33 can be placed; the "work device 30" is assembled on the outer wrench 2〇 opposite the front and rear ring grooves 21 The I5 includes a control sleeve 31, a compression bullet, a top bead 33 and a positioning ring 34, wherein the control sleeve 31' has an internal shape. The first step ring 311, the second step ring 312, the third step ring 313, and the fourth step % 314 of the ^^y coin; the first -P shape % 311 can accommodate a compression magazine. The 312-series of the second-order ring 312 is smaller than the -M366445 step-shaped ring 311, and is slightly larger than the outer diameter of the hollow tube of the monthly production of the month; the outer diameter of the second is greater than the second-order (four) 2, When the control sleeve 31 is displaced until the bead hole 23 is opposite to the third step ring 313, the first wrench 20 is formed by the door 1 and the outer handle (313) and the outer bead 33 are accommodated; The fourth-order paste can be used for a set of 34 ring sleeves; the curling spring 32 is sleeved between the outer part of the outer wrench 2 and the control sleeve, and the two ends can be respectively buckled against the outer wrench 2〇 %<211 and the inner wall of the first step ring 311, · bead 33, the sleeve is placed inside the bead hole of the outer wrench 2 (); the mountain is set = ring 34, which can be tightly fitted to the fourth The stepped ring 314 has an outer end surface that can abut against the outer wrench 20 and then the buckle 221; 13 lies in that the implant 1G is provided with a symmetrical convex wrench 2G on the opposite side of the end of the implant 1G. Concave %, available for description The 13-wire limit of the cooked part and the displacement adjustment of the money; _ 2 is composed of the above components, when in the natural state, such as the third and fourth figures = the 32-end of the constricted spring abuts against the front buckle 2 ιι, the other end Pushing the inner wall of the first step % 311, so that the control sleeve _ swears one end of the wrecked wrench - nrr the apex A 丨 丨 丨 凹 凹 凹 , , , , , , , , , , , , 12 12 12 The fixed fixation of the sex is separated.
