Description

Technical Field

[0001] The utility model relates to the technical field of bolt disassembly tools, in particular to a handheld bolt quick disassembly tool. Background Art

[0002] Traditionally, bolts are usually removed by using a wrench or a screwdriver, but the wrench and the screwdriver require a certain amount of space and it is rather strenuous to manually remove a large number of bolts. Therefore, there is an electric screwdriver in the prior art for removing bolts, but the contact shaft of the electric screwdriver needs to contact the front side of the bolt nut end, so it still requires a certain amount of space to move. When removing bolts in a small space or a narrow space, it is strenuous to use an electric or manual screwdriver, resulting in a cumbersome and time-consuming bolt removal process. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a handheld bolt quick disassembly tool to solve the problem that bolts are inconvenient to disassemble in a narrow space.

[0004] To achieve the above-mentioned purpose, the utility model provides a hand-held bolt quick-release tool, including a handle body and a plate body, a rotating shaft is rotatably arranged at the starting end of the plate body, the end of the plate body is connected to the handle body, a linkage cavity is hollowed out in the plate body, a head gear and a tail gear are rotatably arranged in the linkage cavity, the rotating shaft is coaxially connected to the head gear, a plurality of follower gears are meshed and transmitted between the head gear and the tail gear, a driving member for driving the tail gear to rotate is arranged at the end of the plate body, a disassembly sleeve is arranged on the rotating shaft, and a disassembly hole for clamping and cooperating with the end of an external bolt nut is opened on the disassembly sleeve.

[0005] The benefits of adopting the above technical solution are: the operator holds the handle and pushes the plate into the narrow space, and then moves the plate to align the disassembly sleeve with the bolt to be removed and the nut end of the bolt is engaged with the disassembly hole. Thereafter, the operator drives the tail gear to rotate through the driving member, and the tail gear rotates and drives the adjacent slave gears to rotate synchronously, and several slave gears are arranged in meshing relationship, so that when the slave gear meshing with the tail gear rotates, it will drive other slave gears to rotate synchronously. At this time, the synchronous rotation of several slave gears drives the head gear to rotate, thereby driving the disassembly sleeve to rotate through the rotating shaft, thereby realizing the removal of the bolt. The above technical setting facilitates the removal of bolts in a narrow space and improves the removal efficiency. At the same time, the electric drive removal does not require the operator to manually swing the handle when removing the bolt, thereby reducing the physical exertion of the operator.

[0006] The utility model is further configured as follows: a small motor is arranged at the end of the plate body, an output end of the small motor penetrates into the linkage cavity and is coaxially connected with the tail gear, the small motor is the driving member, and a switch assembly for opening and closing the small motor is arranged on the handle body.

[0007] The benefits of adopting the above technical solution are: the small motor is used to drive the tail gear to operate, thereby ensuring that the head gear drives the disassembly sleeve to operate normally; in the above technology, the switch assembly is arranged on the handle body to facilitate the operator's operation, and the small motor is an existing technology, so its structure and function will not be described in detail.

[0008] The utility model is further configured that: the disassembly sleeve is detachably connected to the rotating shaft.

[0009] The benefit of adopting the above technical solution is that the disassembly sleeve in the above technology can be detachably connected to the rotating shaft, so that the operator can replace different styles of disassembly sleeves according to different types of bolts and nuts, that is, replace disassembly holes of different shapes to adapt to different bolts.

[0010] The utility model is further provided with: a mounting groove is provided at the bottom of the disassembly sleeve, a mounting block is provided at the end of the rotating shaft, the radial cross section of the mounting block is hexagonal, the radial cross section of the mounting block is adapted to the radial cross section of the mounting groove, and the mounting block and the mounting groove are plug-fitted and matched.

[0011] The advantages of adopting the above technical solution are as follows: in the above technology, the quick connection between the disassembly sleeve and the rotating shaft can be achieved through the clamping of the installation groove and the installation block, thereby improving the installation efficiency and ensuring that the disassembly sleeve can be driven to operate normally when the rotating shaft rotates.

[0012] The utility model is further configured that light strips are provided on both side walls of the plate body along the length direction thereof.

[0013] The benefit of adopting the above technical solution is that the light strip in the above technology is used in a dim light source or a dark environment, so that the operator can find the position of the bolt to be disassembled.

[0014] The utility model is further provided with: a gripping sleeve for an outside operator to hold is arranged on the outer peripheral wall of the handle body, and the gripping sleeve is made of rubber material.

[0015] The benefit of adopting the above technical solution is that the setting of the gripping sleeve in the above technology facilitates the operator to grip the handle body, while increasing the friction torque between the operator's hand and the handle body. BRIEF DESCRIPTION OF THE DRAWINGS
