[0027] Example:

[0028] See also Figure 1-3An assembled crank-type socket wrench includes a base 1, one end of the base 1 is rotatably connected to a rocker 2, and a storage cavity 3 is opened at the end of the base 1 away from the rocker 2, and a magnet 4 is installed on the inner wall of the storage cavity 3, one end of the base 1 is fixedly connected to an external sleeve 5, the inner cavity of the external sleeve 5 is connected to the storage cavity 3, and a plurality of adjustable sleeves 6 are arranged inside the external sleeve 5, and the plurality of adjustable sleeves 6 are mutually sleeved, and the adjustable sleeve 6 includes an inner sleeve 601, an inner sleeve One end of 601 close to the magnet 4 is fixedly connected to a limiting ring 602, and the limiting ring 602 is set to a magnetic material. The sizes of the multiple internal sleeves 601 increase from the inside to the outside, and the two adjacent internal sleeves 601 abut against each other. The inner cavity of the outer sleeve 5 matches the shape of the outermost inner sleeve 601. The sizes of the multiple limiting rings 602 increase from the inside to the outside, and the two adjacent limiting rings 602 abut against each other, and the outermost limiting ring 602 abuts against the inner wall of the outer sleeve 5.

[0029] A socket wrench is a hand tool used to tighten or loosen nuts or bolts. It consists of a socket and a handle, which is used to provide leverage and rotational force. Existing socket wrench sets are mostly composed of a handle and multiple sockets. The inner cavity sizes of the multiple sockets are different, which can be suitable for fasteners of various sizes. The sockets and the handle can be connected so that users can replace different sockets according to the usage scenarios. The sizes of the multiple internal sleeves 601 increase from the inside to the outside, and the two adjacent internal sleeves 601 abut against each other. The inner cavity of the outer sleeve 5 matches the shape of the outermost internal sleeve 601. The sizes of the multiple limit rings 602 increase from the inside to the outside, and the two adjacent limit rings 602 abut against each other, and the outermost limit ring 602 abuts against the inner wall of the outer sleeve 5.

[0030] In this solution, multiple internal sleeves 601 are integrated together and nested with each other, which saves space to the maximum extent. Multiple limiting rings 602 and magnets 4 magnetically repel each other, so multiple internal sleeves 601 are pushed toward the external sleeve 5. The mutual engagement of multiple limiting rings 602 and multiple internal sleeves 601 can limit the internal sleeve 601 to the inside of the external sleeve 5 to prevent the internal sleeve 601 from falling out of the external sleeve 5. During use, the user only needs to place one end of the opening of the external sleeve 5 against the fastener to be removed, and then press downward. At this time, according to the size of the fastener, one or more internal sleeves 601 will be squeezed into the storage cavity 3. The user can rotate the external sleeve 5 appropriately so that the fastener can finally be engaged with the inner cavity of the internal sleeve 601 that matches it. Then the user can rotate the rocker 2 to rotate and disassemble the fastener. The rocker 2 can be rotated on the base 1, so that the user can rotate the fastener according to a suitable angle. Each internal sleeve 601 can be adapted to a fastener of a certain size separately, among which the inner cavity size of the smallest internal sleeve 601 determines the smallest size of fastener that the device can adapt to, and the size of the inner cavity of the outer sleeve 5 determines the largest size of fastener that the device can adapt to. When the user takes the removed fastener out of the outer sleeve 5, due to the magnetic repulsion between the multiple limit rings 602 and the magnet 4, the multiple internal sleeves 601 will be reset and re-installed together, making it convenient for the user to remove fasteners of other different sizes. Compared with the traditional wrench set, the present solution integrates the multiple internal sleeves 601 into one, so that the user does not need to frequently change the sleeves when installing and removing fasteners, but can quickly fix them according to the size of the fasteners, effectively improving work efficiency. Moreover, the integration of the multiple internal sleeves 601 can be convenient for the user to carry, so that the user no longer needs to carry a tool box for loading multiple sleeves.

[0031] See also Figure 4 The outer end of the base 1 is threadedly connected to a screw rod 7, one end of the screw rod 7 extends into the storage cavity 3, and multiple internal sleeves 601 are provided with positioning holes 603. The multiple positioning holes 603 have the same size and match the screw rod 7.

[0032] In this solution, when installing and removing fasteners of different sizes, the user can quickly use different inner sleeves 601 to fix the fasteners without frequent replacement. However, when facing a large number of fasteners of the same size for installation and removal, the user's repeated actions of squeezing the outer sleeve 5 downward and finding a suitable inner sleeve 601 to match the fastener will take a certain amount of time, resulting in a decrease in work efficiency. Therefore, in this solution, positioning holes 603 are opened on multiple inner sleeves 601. When the user inserts a fastener of a specific size into the outer sleeve 5, the fastener will push the multiple inner sleeves 601 into the base 1. Inside, the user can rotate the screw 7 to make the screw 7 enter the inner cavity of the base 1, and the screw 7 will pass through the multiple positioning holes 603. At this time, if the user takes out the fastener, the multiple internal sleeves 601 in the base 1 will be pushed by the magnet 4, but due to the restriction formed by the screw 7, they cannot be reset. Therefore, when the user installs and removes other fasteners of the same size, they can achieve quick clamping, saving some positioning time and effectively improving work efficiency. After use, the user rotates the screw 7 to disengage the screw 7 from the multiple positioning holes 603, so that the multiple internal sleeves 601 can be reset.

[0033] Working principle:

[0034] During use, the user places one end of the opening of the outer sleeve 5 against the fastener to be removed, and then presses downward. At this time, according to the size of the fastener, one or more inner sleeves 601 will be squeezed into the storage cavity 3. The user can rotate the outer sleeve 5 appropriately so that the fastener can finally be engaged with the inner cavity of the matching inner sleeve 601. Then the user can rotate the rocker 2 to rotate and remove the fastener. The rocker 2 can be rotated on the base 1, so that the user can rotate the fastener according to the appropriate angle. Each inner sleeve 601 can be adapted to a fastener of a certain size separately. When the user removes the removed fastener from the outer sleeve 5, due to the magnetic repulsion between the multiple limit rings 602 and the magnet 4, the multiple inner sleeves 601 will be reset and re-installed. At the same time, when facing the installation and removal of a large number of fasteners of the same size, the user can first insert the fastener of that size into the outer sleeve 5, and the fastener will push the multiple internal sleeves 601 into the interior of the base 1. At this time, the user can rotate the screw 7 to make the screw 7 enter the inner cavity of the base 1, and the screw 7 will pass through the multiple positioning holes 603. At this time, the user takes out the fastener. Although the multiple internal sleeves 601 in the base 1 will be subjected to the thrust of the magnet 4, they cannot be reset due to the restriction formed by the screw 7. Therefore, when the user installs and removes the remaining fasteners of the same size, it can be quickly connected, saving some positioning time. After use, the user rotates the screw 7 to disengage the screw 7 from the multiple positioning holes 603, and the multiple internal sleeves 601 can be reset.
