Detailed Description
The utility model discloses do not receive the restriction of following embodiment, can be according to the utility model discloses a technical scheme and actual conditions determine concrete implementation.
In the present invention, for convenience of description, the description of the relative position relationship of the components is described according to the layout mode of the attached drawing 1 in the specification, such as: the positional relationship of front, rear, upper, lower, left, right, etc. is determined in accordance with the layout direction of the drawings of the specification.
The invention will be further described with reference to the following examples and drawings:
as shown in the attached drawing 1, the reversing movable tool bit screwdriver comprises a handle 1, a switching sleeve 2, a universal joint 3, an installation block 4 and a replacement tool bit 5, wherein the handle 1 is fixedly installed on the outer side of the left end of the universal joint 3, the switching sleeve 2 is sleeved on the outer side of the right part of the handle 1, the installation block 4 is fixedly installed on the right end of the universal joint 3, a fixed block 5 is fixedly installed on the right end of the installation block 4, a mounting hole with a rightward opening is formed in the inner side of the right end of the fixed block 5, and the left part of the. When the universal joint type tool bit is used, the switching sleeve 2 can slide rightwards to be positioned in the middle of the universal joint 3, so that the universal joint 3 cannot rotate, the handle 1 cannot be bent, the handle 1 and the replacing tool bit 6 are in a straight shape, and the replacing tool bit 6 can be selected according to needs, such as a cross tool bit, a straight tool bit or an inner hexagon wrench; when the switching sleeve 2 is positioned on the outer side of the right part of the handle 1, the handle 1 can be bent to adjust the direction of the handle 1 and the direction of the replacing tool bit 6, and when the handle 1 and the replacing tool bit 6 are L-shaped, the operation is more labor-saving, the length of the utility model is shortened, the switching sleeve is suitable for scenes needing larger torsion and can be suitable for the position with limited operation space, and the proper replacing tool bit 6 can be selected according to the requirement; the inner side of the mounting hole is of an inner hexagon shape, and the tool is suitable for most of the replaceable tool bits 6. The utility model has the advantages of reasonable and compact structure, convenient to use, it can transfer to handle 1 fast effectively through setting up universal joint 3, makes handle 1 realize that the straight shank switches to L handle fast to the realization can increase the laborsaving operation of moment of torsion, has safety, laborsaving, simple and convenient and efficient characteristics.
The reversing movable bit screwdriver can be further optimized or/and improved according to actual requirements:
as shown in fig. 1, the mounting block 4 is a magnet block. The magnet block is made of a known magnetic material such as a permanent magnet, as required.
