Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] Such as figure 1 , figure 2 As shown, a socket screwdriver with adjustable sleeve rod length is used for the disassembly and assembly of hexagon socket screws, and specifically includes a cylindrical sleeve rod 1 and a handle 2 connected with the sleeve rod. The front end of the rod is provided with a sleeve 3 that can be adapted to the screw head of the hexagon socket screw. The sleeve includes a circular cylinder 31, and 12 convex lines 32 are arranged on the inner side wall of the cylinder. The convex lines extend along the axial direction of the cylinder and are equally spaced on the inner side of the cylinder. The corresponding central angle is 30 degrees. The convex strip includes two symmetrical sides on the left and right and two slopes connected in a herringbone shape between the left and right sides, so that the top of the c...

The invention discloses a sleeve-rod-length-adjustable sleeve screwdriver. The sleeve-rod-length-adjustable sleeve screwdriver comprises a sleeve rod and a handle connected with the sleeve rod, wherein a sleeve is arranged at the front end of the sleeve rod. A lateral long groove extending to the front end face is formed in the side face of the handle, the back section of the sleeve rod is clamped in the lateral long groove, a rotating shaft is arranged between the two opposite side faces of the lateral long groove, an adjusting long groove penetrating through the outer side face in a radial-direction mode is formed in the back end of the sleeve rod, the rotating shaft is connected in the adjusting long groove in a sliding mode, a first positioning hole matched with the back end of the sleeve rod is formed in the side face of the back end of the lateral long groove, a second positioning hole matched with the back end of the sleeve rod is formed in the bottom face, close to the back end of the handle, of the lateral long groove, and the axes of the first positioning hole and the second positioning hole and the axis of the rotating shaft are intersected at one point. By means of the sleeve screwdriver, the effective using length of the sleeve rod can be conveniently and rapidly adjusted so that the requirements of different using occasions can be met; meanwhile, after the length of the sleeve rod is adjusted, the structure is stable, reliable and convenient to bring and use.
Description
technical field [0001] The invention relates to a hardware tool for disassembling and assembling threaded fasteners, in particular to a socket screwdriver with adjustable sleeve rod length. Background technique [0002] The socket screwdriver is a common hardware tool used for disassembling hexagonal screws. Its common structure includes a handle and a sleeve rod fixed on the handle. The end of the sleeve rod is provided with a sleeve. There is a hexagonal groove or a dodecagonal groove (commonly known as a plum blossom sleeve) that fits the hexagonal head of the hexagonal screw. When disassembling the screw, you only need to put the sleeve at the end of the sleeve rod on the screw On the hex head, and then turn the handle to remove the screw. Since the sleeve can simultaneously act on the six sides of the hexagonal head of the screw to generate a large torque, the socket screwdriver has the advantages of not being easy to slip and having a large torque compared with a fixe...
