Description

Technical Field

[0001] The utility model belongs to the technical field of electric wrench joints, in particular to a steering joint for an electric wrench. Background Art

[0002] An electric wrench is an electric tool for tightening and loosening bolts and nuts. It is mainly used for the initial tightening and final tightening of large hexagonal high-strength bolts installed in steel structure bridges, factory buildings, chemical industry, and power generation equipment, as well as the initial tightening of torsion shear type high-strength bolts, as well as occasions with strict requirements on the torque or axial force of bolt fasteners.

[0003] A Chinese patent with publication number CN213165117U discloses a universal joint, characterized in that it includes a socket, an adapter, a connecting rod, a first latch, a second latch, a first spring and a second spring, wherein one end of the socket has a fitting opening for connection with a sleeve, the other end of the socket is formed with two symmetrical first pivot ears, a space for disposing one end of the connecting rod is reserved between the two first pivot ears, one end of the adapter has a connecting rod for connection with a wrench, and the other end of the adapter is formed with two symmetrical second pivot ears.

[0004] The steering joint of the wrench in the above-mentioned prior art still has some shortcomings in actual use. For example, the universal adapter of the traditional electric wrench is generally fixed for removing the hexagonal nuts or bolts. Each fitting joint must be matched with a set of universal joint structures. Therefore, when it is necessary to replace hexagonal nuts or bolts of different models, they must also be replaced as a whole, resulting in a large waste of material resources. Utility Model Content

[0033] Principle and advantages of use: During use, when replacing and installing different socket joints 6, the connecting sleeve 701 on the socket joint 6 and the connecting shell 706 on the first steering sleeve 1 are plugged in. When the connecting sleeve 701 is inserted, it contacts and squeezes the inclined surface of the card-in end of the card block 703. At the same time, the edge of the connecting sleeve 701 slides and squeezes the inclined surface of the card-in end of the card block 703, so that the limit plate 705 connected to the card block 703 slides close to each other in the connecting shell 706 and compresses the spring 704. When the connecting sleeve 701 is inserted into the outer side of the connecting shell 706, the connecting sleeve 701 is pressed against the inclined surface of the card-in end of the card block 703. After contacting the limiting ring 702, the snap-in end of the clamping block 703 corresponds to the snap-in hole 8 of the connecting sleeve 701. At this time, the spring 704 resets and pushes the limiting plates 705 away from each other, so that the clamping block 703 connected to the limiting plates 705 is snapped into the snap-in hole 8 of the connecting sleeve 701 to fix it. When disassembling, it is only necessary to squeeze the rectangular block 10 outside the connecting sleeve 701 at the same time, so that one end of the rectangular block 10 pushes the snap-in end of the clamping block 703 out of the snap-in hole 8, and then the socket 6 can be directly and quickly removed from the connecting shell 706 at the first steering sleeve 1;

[0034] When the adapted nut is disassembled, if the nut is stuck on the socket 6, it is only necessary to hold the socket 6 and then swing the pull plate 501 toward the socket 6 to push out the nut stuck in the socket 6.
