It is possible to solve the problem that a flexible type such as a pipe wrench has, and that the screw is damaged if the adjustment is slightly loose due to the operation of sandwiching parallel surfaces of the screw. [Structure] A parallel gripping surface 1 is provided with a square gripping opening 2 so as to sandwich a corner surface of a screw so that it can act. Further, in order to improve the adhesion and accuracy when gripping the screw, the adjustment screw 3 By reducing the pitch and doubling the number of threads, loosening during use is prevented.

Description

[Detailed description of the device] [Industrial application]

機械工具のねじ回しには、片口型、引掛型、箱型、メガネ型など、種々あるが、いづれも固定型である。これに対して自在型には、モンキースパナ、パイプレンチなどあるが、作業効率もよく、利用度も高い。 There are various types of screwdrivers for machine tools, such as single-ended type, hook type, box type, and eyeglass type, but all are fixed types. On the other hand, there are monkey spanners, pipe lentches, etc. in the free type, but they have good work efficiency and high utilization.

[Prior Art]

既存の自在スパナは、ねじの平行面を挾み、作用するので角面を損傷しやすい。又、調節ねじのピッチが荒いため、脱着の度に緩み、訂正しながら使用しなければならない。 The existing universal wrench works by pinching the parallel surface of the screw and acting, so it is easy to damage the corner surface. Also, the pitch of the adjusting screw is rough, so it must be loosened every time it is attached and detached, and be corrected.

[Problems to be solved by the device]

平行挾面だけの作用では無理があり、ねじの角面に作用させるようにする。又、使用中の緩み解消のため、調節ねじの改良が必要である。 It is not possible to work only with parallel flanks, so try to work on the corners of the screw. In addition, the adjustment screw needs to be improved in order to eliminate looseness during use.

[Means for Solving the Problems]

１，自在スパナの挾接面を多少長く取り、前方を平行挾面とし、後方にねじの角を挾められるように、角挾口を付け、ねじの２角面に作用させることにより密着性もよく、ねじの損傷も防止できる。２．角挾口を付けることにより、調節ねじの負荷も増化してくるので、ねじ山条数を多くとり、精密化と、ねじ山にかゝる力を分散させる。３，自在スパナは、固定型スパナのように、全角を挾むことはできない。そのため、固いねじの脱着に不向きである。これを補うため、柄の部分にねじ穴を付け、機能を補強する。 1. Make the contact surface of the adjustable spanner a little longer, make the front parallel to the parallel surface, attach the angled opening so that the corners of the screw can be caught in the rear, and make contact with the two diagonal surfaces of the screw. It has good performance and can prevent damage to screws. 2. Since the load on the adjusting screw is also increased by adding the square opening, the number of thread threads is increased, the precision is improved and the force related to the thread is dispersed. 3. Unlike the fixed spanner, the adjustable spanner cannot hold the full width. Therefore, it is not suitable for attaching and detaching hard screws. To compensate for this, screw holes are added to the handle to reinforce its function.

[Effect of the device]

本案を，既存のモンキースパナ２００ＭＭ、２５０ＭＭ、３００ＭＭで改良し、試作して実地に活用した経験と、自動車関係者から、好評を得ている。 This plan has been improved by the existing Monkey Spanner 200MM, 250MM, and 300MM, and it has been well received by the automobile industry and the experience of using it for trial production.
