The rear wrench rod 1 and the front wrench rod 2 of this structure can be movably connected by matching the fixing rod 7 with the rotating sleeve 8 to adjust the bending angle between the two at will, and the use angle of the wrench head 3 can be flexibly adjusted, and the limiting mechanism provided on the front wrench rod 2 can quickly lock the bending angle between the rear wrench rod 1 and the front wrench rod 2, so that The clamping structure formed by the rear wrench rod 1, the front wrench rod 2 and the wrench head 3 can adapt to completing multi-angle tightening operations in a narrow space, greatly improving the operational flexibility and efficiency under complex working conditions, while ensuring the safety and accuracy of fastener processing. At the same time, when the rear wrench rod 1 and the front wrench rod 2 adjust the bending angle, they will synchronously drive the arc piece 9 to be retracted and released in the arc sleeve 10, further ensuring the stability of the rear wrench rod 1 and the front wrench rod 2 after adjusting the bending angle. The limiting mechanism on the front wrench rod 2 includes a groove 21, a shift block 22, an elastic block 23, and an insertion rod 24. The groove 21 is provided at one end where the front wrench rod 2 is connected to the rear wrench rod 1, the shift block 22 is movably arranged inside the groove 21, and the elastic block 23 is connected between the outer side of the shift block 22 and the inner side of the groove 21. The outer ends of the plug rods 24 slide through the outside of the front wrench rod 2, and the outer ends of the fixed rods 7 are surrounded by a plurality of circular holes that match the outer end structures of the plug rods 24. In the process of adjusting the bending angles of the rear wrench rods 1 and the front wrench rods 2 with this structure, the operator can squeeze the elastic block 23 by shifting the shift block 22 inside the groove 21 until the fixed rod 7 rotates to a suitable angle in the rotating sleeve 8. After the shift block 22 is released, the outer ends of the plug rods 24 will be driven to extend into the corresponding circular holes on the fixed rods 7. After the fixed rods 7 are limited, the bending angle of the rear wrench rods 1 can be locked to ensure the stability of the rear wrench rods 1 and the front wrench rods 2 when used in conjunction with each other. The outer ends of the arc pieces 9 slide into the interior of the arc sleeve 10.The side where the arc sleeve 10 is connected to the arc sheet 9 is connected with a locking screw 14 through a threaded structure. When the arc sheet 9 of this structure is extended to a suitable position inside the arc sleeve 10, the locking screw 14 can be rotated on the arc sleeve 10 to press against the arc sheet 9, so as to limit the connection between the arc sleeve 10 and the arc sheet 9, further ensuring the stability of the rear wrench rod 1 and the front wrench rod 2 when used in conjunction with each other. An extension rod 5 is provided at the rear end of the rear wrench rod 1, and a pull-out piece 6 is provided at one end of the extension rod 5 connected to the rear wrench rod 1, and a pull-out groove that matches the structure of the pull-out piece 6 is provided inside the rear end of the rear wrench rod 1, and both sides of the rear end of the rear wrench rod 1 are connected to fixing screws through a threaded structure, and both sides of the pull-out piece 6 are provided with a plurality of screw holes. The extension rod 5 of this structure can be inserted through the pull-out piece 6. Different lengths can be pulled in the pull-out groove at the rear end of the rear wrench rod 1 and fixed in the corresponding screw hole on the pull-out piece 6 by a fixing screw, so that the length adjustment of the rear wrench rod 1 can be achieved, further improving its practicality. The rear end of the wrench head 3 is provided with a clamping sleeve 11, and the outer end of the front wrench rod 2 is provided with a clamping interface that matches the structure of the clamping sleeve 11. The outer end of the front wrench rod 2 is inserted with a locking shaft 12 inside the clamping sleeve 11, and the two ends of the locking shaft 12 are connected with locking nuts 13 through a threaded structure. The wrench head 3 of this structure can be inserted with the clamping sleeve 11 in the clamping interface at the outer end of the front wrench rod 2 and the locking shaft 12 is inserted as a whole, and the two ends of the locking shaft 12 are fixedly connected with the locking nuts 13, which makes it convenient to disassemble and replace the wrench head 3 at the outer end of the front wrench rod 2, making it more convenient to use.

[0018] Working principle: when using the compressor chassis clamp, first, fit the wrench head 3 into the clamping interface at the outer end of the front wrench rod 2 through the clamping sleeve 11, and then insert the locking shaft 12 as a whole into the outer end of the front wrench rod 2, and then connect the locking nuts 13 at both ends of the locking shaft 12. When the wrench head 3 is installed at the outer end of the front wrench rod 2, the use angle can be adjusted in advance according to the spatial characteristics of the compressor chassis. At this time, the rear wrench rod 1 and the front wrench rod 2 can be bent arbitrarily through the cooperation of the fixed rod 7 and the rotating sleeve 8. During this process, the operator squeezes the elastic block 23 by shifting the shift block 22 inside the groove 21 until the fixed rod 7 is rotated to a suitable angle in the rotating sleeve 8, until the wrench head 3 is controlled at a suitable use angle, and then releases the shift block 22. After the shift block 22 is released, it will be in the elastic block 23 Under the elastic force, the outer end of the insertion rod 24 is driven to extend into the corresponding circular hole on the fixing rod 7. After the fixing rod 7 is limited, the bending angle of the rear spanner rod 1 can be locked, and when the rear spanner rod 1 and the front spanner rod 2 adjust the bending angle, the arc piece 9 will be synchronously driven to be retracted and released in the arc sleeve 10. The locking screw 14 can be rotated on the arc sleeve 10 to press against the arc piece 9, so as to limit the connection between the arc sleeve 10 and the arc piece 9, thereby ensuring the stability of the rear spanner rod 1 and the front spanner rod 2 when used in conjunction with each other. At the same time, the extension rod 5 can also be pulled to different lengths in the pulling groove at the rear end of the rear spanner rod 1 through the pulling piece 6 and fixed in the corresponding screw hole on the pulling piece 6 by using a fixing screw, so as to adaptively adjust the use length of the rear spanner rod 1, thereby completing a series of tasks.
