Embodiment 1

[0040] according to Figure 1 to Figure 7 As shown, a combined multipurpose wrench includes a torque wrench 1 and a dead end open end wrench 2, the torque wrench 1 and the dead end open end wrench 2 are detachably connected, and a steel wire rope is provided between the torque wrench 1 and the dead end open end wrench 2 3. One end of the wire rope 3 is connected to the open end wrench 2, and the other end of the wire rope 3 is connected to the torque wrench 1 through a recovery mechanism. The torque wrench and the open end wrench are combined into one, and the wire rope 3 ensures that the two wrenches will not be scattered when they are used separately. In normal times, the torque wrench 1 and the open end wrench 2 are installed together, and the connected wire rope 3 is stored on the recovery mechanism, so that it can be used as a two-end wrench. If it is an operation with torque requirements, use a torque wrench. If not, you can also use a dull-headed open-end wrench. When...

Embodiment 2

[0051] according to Figure 8 As shown, a slot 25 is arranged in the open end wrench 2, and a positioning screw 26 is provided on the outer cylindrical surface of the open end wrench 2 . The slot 25 is in the shape of a cuboid, and the open-ended wrench 2 is inserted into the slot 25 and locked and fixed by the screw 26 . When connecting two unfixed coaxial adapters, loosen the set screw 26, pull out the open end wrench 2 from the slot 25, and use the open end wrench 2 and the torque wrench 1 to clamp the two ends respectively. The adapter is tightened and fixed. After use, reinsert the open-end wrench 2 into the slot 25 and lock it with the set screw 26. The number of set screws 26 is at least two to prevent the open-ended wrench 2 from being used alone. The open end wrench 2 moves.

Embodiment 3

[0053] according to Figure 9 As shown, the open-ended wrench 2 is locked by a locking plate 27, one end of the locking plate 27 is hinged with the open-end wrench 2, and the other end of the locking plate 27 is detachably connected with the open-end wrench 2 through screws; Open-end wrench 2 wraps one deck binding hand 28, and one end of binding hand 28 is connected with torque wrench 1, and the other end of torque wrench 1 is provided with Velcro 29. Clamp the open end wrench 2 in the groove through the locking plate 27. When two unfixed coaxial adapters are connected, the screw at one end of the locking plate 27 is unscrewed, and the locking plate 27 is turned to take out the screw. Open-end wrench 2, use the open-end wrench 2 and the torque wrench 1 to clamp the adapters at both ends and tighten them. After use, put the open-end wrench 2 back into the groove, turn the locking plate 27, and pass the screw Fix the locking plate 27, and then wrap the binding hand 28 on the c...

Abstract

The embodiment of the invention discloses a combined type multi-purpose spanner. The combined type multi-purpose spanner comprises a torque spanner and a dull-head open spanner. The torque spanner isdetachably connected with the dull-head open spanner. A steel wire rope is arranged between the torque spanner and the dull-head open spanner. One end of the steel wire rope is connected with the dull-head open spanner, and the other end of the steel wire rope is connected with the torque spanner through a recovering mechanism. The combined type multi-purpose spanner can serve as a two-head spanner, if operation with the torque requirement is carried out, the torque spanner is used, and if operation without the torque requirement is carried out, the dull-head open spanner can be used. When twounfixed coaxial adapters need to be connected, the two spanners are separated and clamp the adapters at the two ends to screw and fix the adapters.

Description

technical field [0001] The invention relates to the technical field of assembly and disassembly tools, in particular to a combined multipurpose wrench. Background technique [0002] A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts, and other openings or casings that are threaded to hold bolts or nuts. Wrenches are usually made of structural steel of carbon or alloy materials. [0003] There are more and more applications of coaxial cables in the field of radio frequency applications, which increases the number of coaxial adapters. When manually connecting these coaxial adapters, a wrench is a must-have tool. Accuracy requirements, when the connector joints are tightened, the strength requirements are relatively high. At this time, the torque wrench came into being. [0004] Taking the application of an oscilloscope as an example, most of the current oscilloscopes are used with SMA ...
