no. 1 example

[0015] The first embodiment, as shown in Fig. 1, a universal wrench includes a wrench 1 and a handle 2. The wrench 1 and the handle 2 are respectively installed at both ends of a flexible shaft, the wrench 1 is a sleeve, and the wrench 1 It is detachably connected with the flexible shaft, and the flexible shaft is covered with a sleeve 3.

[0016] The second embodiment, as shown in Figure 2, the universal wrench includes a wrench 1 and a shaft 4, the shaft 4 is sleeved with a sleeve 5, and the wrench 1 and the shaft 4 are respectively mounted on two flexible shafts that can be bent. At the end, the wrench 1 is a sleeve, and the wrench 1 is detachably connected with the flexible shaft, and the flexible shaft is covered with a sleeve 3. When in use, sleeve the shaft sleeve 5 on the shaft 4, and the shaft sleeve 5 and the shaft 4 together serve as a handle to increase the length of the grip part, which is more convenient to use; after use, the shaft sleeve 5 can be removed.

no. 3 example

[0017] In the third embodiment, on the basis of the second embodiment, positioning marbles and positioning holes are provided at the socket joint of the shaft 4 and the shaft sleeve 5 to movably connect the shaft 4 and the shaft sleeve 5 together. When in use, the length of the grip part can be increased after pulling the shaft sleeve 5, which is convenient to use. After use, press the shaft 4 into the shaft sleeve 5 to avoid taking up too much space

Abstract

The invention discloses a universal wrench. The wrench is characterized in that: the invention comprises a wrench head and a handle, wherein the wrench head and the handle are respectively arranged on the two sides of a flectional flexible shaft. The universal wrench of the invention can solve problems of disassembly and assembly of a bolt arranged at a hidden position in a small space effectively and can reduce the construction time, guarantee the construction quality and increase the working efficiency.

Description

Technical field [0001] The invention relates to a wrench. Background technique [0002] Some bolts are installed in small and concealed locations. It is difficult to use ordinary wrenches to disassemble and assemble during maintenance and repair, which causes problems such as increased construction difficulty, prolonged construction time, low labor efficiency, and inadequate bolt tightening. Summary of the invention [0003] The purpose of the present invention is to provide a universal wrench suitable for disassembling and disassembling bolts in narrow and concealed positions in light of the disadvantage that the wrench in the prior art cannot disassemble and assemble bolts in narrow and concealed positions. [0004] In order to achieve the above objectives, the present invention is achieved through the following technical solutions: [0005] The universal wrench is characterized in that it comprises a wrench and a handle, and the wrench and the handle are respectively installe...
