Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, and more specifically to a force-applying tool with adjustable angle. Background Art

[0002] The function of the wrench force rod is to install a straight-handle wrench or a socket wrench. When tightening a bolt or a nut, the wrench force rod is the hand-held part, and the straight-handle wrench and the socket wrench are the parts that cooperate with the bolt or the nut. The worker tightens or loosens the bolt or the nut by holding the force rod and rotating it multiple times.

[0003] For example, a force wrench disclosed in the prior art includes: a rod No. I, a rod No. II, a rod No. III, a vertical rod, and a wrench shaft; the side of the rod No. I is connected to a vertical rod; one end of the vertical rod is provided with a receiving groove; the receiving groove is used in conjunction with the wrench shaft; the cross section of the wrench shaft is a regular quadrilateral, and a marble is provided on the wrench shaft; the marble is used to increase the friction between the wrench shaft and the fastener; the rod No. II is connected to one end of the rod No. I; the rod No. III is connected to one end of the rod No. II. In this technical solution, a wrench can be inserted and socketed on the wrench shaft, and the bolt can be screwed with the wrench.

[0004] In some large oil supply systems, the flanges at the ends of two adjacent pipelines are connected by bolts and nuts. When the pipeline system needs to be inspected or repaired, a wrench force rod combined with a wrench is needed to tighten the bolts. Figure 1 As shown, for some pipes 6 placed horizontally on the ground, the bolts 7 on the pipe flange ring are close to the ground 8. The above-mentioned prior art force wrench 9 is easily interfered by the ground 8 when tightening the bolt 7, and the activity space of the force wrench 9 is small, so it is necessary to tighten the bolt 7 multiple times and at a small angle until the bolt 7 is tightened or loosened. At the same time, in the pipeline system, the layout of some pipes 6 is relatively compact, and the tightening of some bolts 7 requires the force wrench 9 to be extended into the narrow space formed between the two pipes 6. In this case, the force wrench 9 can only be rotated multiple times and at a small angle, resulting in low tightening efficiency of the bolt 7. Utility Model Content

[0005] In view of the problem that the movement of the force wrench in the above-mentioned prior art is easily interfered by the pipeline and the ground, resulting in low bolt tightening efficiency, the utility model provides an angle-adjustable force tool, which can avoid interference from the ground or pipeline, increase the movement space, and improve the bolt tightening efficiency.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0007] An angle-adjustable force tool comprises a wrench seat for mounting a wrench, a hand-held rod assembly and an angle fixing piece, wherein the angle fixing piece is connected to the hand-held rod assembly, and a first fastening structure and a plurality of second fastening structures are provided on the angle fixing piece, wherein the second fastening structures are distributed on one side of the angle fixing piece with the first fastening structure as the array center and circumference, and one end of the wrench seat is detachably connected to the first fastening structure; the wrench seat is also detachably connected to the second fastening structure.

When in use, the wrench is mounted on the wrench seat, the staff holds the hand-held rod assembly and rotates the hand-held rod assembly, and the torque is transmitted to the wrench through the wrench seat to tighten the bolt. By adjusting the angle between the hand-held rod assembly and the wrench seat, the hand-held rod assembly can be avoided from the horizontal ground or the pipe in the pipeline system, so that the hand-held rod assembly has a larger range of motion, so the angle of each bolt tightening can be increased, which is conducive to improving the tightening efficiency of the bolt.

[0009] The connection between the wrench seat and the first fastening structure and the second fastening structure may be through bolt connection, clamping connection, or other various detachable connecting parts.

[0010] Preferably, the first fastening structure and the second fastening structure both protrude from one side of the angle fixing member; the wrench seat is provided with a first through hole and a second through hole, the first fastening structure passes through the first through hole and transitionally fits with the first through hole, the second fastening structure passes through the second through hole and transitionally fits with the second through hole; the wrench seat and the angle fixing member abut against each other. When adjusting the angle between the wrench seat and the hand-held rod assembly, the wrench seat is pulled off the angle fixing member to disengage the first through hole from the first fastening structure and the second through hole from the second fastening structure; then the first through hole is aligned with the first fastening structure and the second through hole is aligned with another second fastening structure, the wrench seat is pushed until it abuts against the angle fixing member, the first fastening structure is inserted into the first through hole and the second fastening structure is inserted into the second through hole, thereby completing the fixation of the wrench seat.
