[0044] The measuring distance of the length gauge 61 of a single spanner extension rod 6 is 25 cm.
[0045] Working principle:
[0046] According to the construction site, a wrench head 2 of appropriate size is selected according to the bolt diameter, and connected to the connector 3 on the wrench front rod 1 through a swivel structure. According to the construction space, a suitable wrench extension rod 6 is selected; the wrench front rod 1 is connected to the wrench extension rod 6, the wrench extension rod 6 is connected to the wrench extension rod 6, and the wrench extension rod 6 is connected to the wrench rear rod 4 through a buckle joint.
[0047] According to the needs of the site, if the lighting brightness is insufficient, the lighting lamp 11 can be turned on to provide lighting for facilitating construction.
[0048] According to the needs on site, the length can be measured by the length ruler 61 on the spanner extension rod 6, and the measuring distance can be extended by connecting and assembling the spanner extension rod 6.
[0049] According to the needs on site, the horizontal plane and the vertical plane are calibrated by the horizontal calibrator 62 and the vertical calibrator 63 of the spanner extension rod 6. The multifunctional spanner set of the utility model realizes the multifunctional use of a set of spanners except for the additional spanner, thereby improving the working efficiency.
[0050] When tightening or loosening the nut, first set the compass 72 to 0 and fix it with the fixing bolts to prevent the angle from shifting during the work process and affecting the reading. The tightening indication area 73 is set to "red" and the loosening indication area 74 is "green" for easy distinction. The dial 71 is designed with tightening and loosening angle scales of 0° to 180°. According to the principle of compass 72, the rotation of the wrench will drive the pointer to move due to the change in the angle of compass 72. When the wrench is tightening, according to the principle of compass 72, the pointer rotates to the "red" area, and after reaching the position, the angle data is read; for loosening operations, vice versa. The utility model successfully realizes a set of multifunctional wrenches to solve many inconveniences in on-site inspection and maintenance operations, which can greatly improve work efficiency and ensure safe and stable operation of equipment.
