Abstract

The invention discloses a multi-layer sleeve spanner capable of being rotationally unfolded at 360 degrees and a working method. Various spanners used for fastening or removing hexagon bolts at present are mainly divided into two large kinds, namely opening adjustable spanners and torque spanners. Both the two kinds of spanners have advantages and disadvantages, the opening adjustable spanners canoperate bolts with more specifications, however being likely to slide and poor in stability, the torque spanners are good in stability, however being small in using range, and one torque spanner onlycan operate bolts with one or two specifications. The multi-layer sleeve spanner comprises a center hoop (1) and a stress hoop (3), and multiple adjusting hoops (2) are arranged between the center hoop and the stress hoop in sequence in a sleeving mode. The center hoop and the corresponding adjusting hoop are matched, every two adjacent adjusting hoops are matched, and the corresponding adjustinghoop and the stress hoop are matched. The center hoop is connected with the corresponding adjusting hoop through a fixing shaft (4), the multiple adjusting hoops are connected trough the fixing shaft(4), and the corresponding adjusting hoop is connected with the stress hoop through the fixing shaft (4). The multi-layer sleeve spanner is capable of being rotationally unfolded at 360 degrees.

Description

Technical field: [0001] The invention relates to a wrench, in particular to a 360-degree rotating and unfolding multi-layer socket wrench and a working method. Background technique: [0002] At present, there are two main types of wrenches used to fasten or remove hexagonal bolts, one is an open-end adjustable wrench, and the other is a torque wrench. The two types of wrenches have their own advantages and disadvantages. Although the open-ended adjustable wrench can wrench more bolts, it is easy to slip and has poor stability; while the torque wrench has good stability and can be used in a narrow range. One wrench can only wrench one or two types of bolts. Standard bolts, in order to wrench the bolts of various specifications commonly used, the user just needs to have many wrenches, large and small, and it is very inconvenient to use, carry, and keep so many wrenches. Invention content: [0003] The purpose of the present invention is to solve the problems existing in the...
