Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of integrated wrench equipment, in particular to an integrated wrench. Background Art
[0002] To facilitate the installation and removal of bolts, an integrated wrench device is often required. Patent application number CN202020882364.8 discloses a wrench specifically for firefighting equipment installation. The wrench features a scale and pointer, and the threaded shaft and second clip cooperate to quickly adjust the desired bolt size, making it very convenient. A telescopic assembly allows the first and second handles to move away from each other, thereby increasing the force arm and maximizing the force applied to the first and second handles. This wrench, specifically for firefighting equipment installation, has a rational structure, is easy to adjust, and offers the advantages of greater ease of use. It is highly practical and worth promoting. However, according to the disclosed technical solution, existing integrated wrenches often cannot effectively install or remove bolts when one side, bottom, or top of the bolt is blocked. Furthermore, when the wrench is rotated to install or remove a restricted bolt, the wrench's force arm shortens, making it difficult to ensure secure installation or removal.
[0003] Therefore, how to design an integrated wrench has become our current problem to be solved. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated wrench to solve the problems raised in the above background technology. The utility model has a reasonable design and is convenient to use, and is suitable for use in installing and removing bolts.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an integrated wrench, comprising a wrench head and a bayonet, a hand-held assembly installed on the top of the wrench head, the hand-held assembly including a handle and a connecting block, a connecting assembly installed on the bottom of the handle, the connecting assembly including a connecting plate and a socket, an insertion assembly installed on the top of the wrench head, the insertion assembly including an insert plate and a rotating shaft, a locking assembly installed on the rotating shaft, the locking assembly including a retaining groove and a retaining pin, a lever assembly installed on the top of the handle, the lever assembly including a sleeve and a hexagon socket.
[0006] Furthermore, the bayonet is integrally formed at the bottom of the wrench head, the inserting plate is integrally formed at the top of the wrench head, and the connecting plate is integrally formed at the bottom of the handle.
[0007] Furthermore, the socket is opened on the inner side of the connecting plate, the plug-in board is clamped on the inner side of the socket, and the rotating shaft is welded on both sides of the plug-in board.
[0008] Furthermore, the connecting block is integrally formed on the top of the handle, the sleeve is integrally formed on the top of the connecting block, and the hexagonal socket is opened on the inner side of the sleeve.
[0009] Furthermore, both sides of the connecting plate are provided with a slot, and the rotating shaft is clamped inside the slot.
[0010] Furthermore, the retaining grooves are respectively opened on the inner sides of the rotating shaft and the connecting plate, and the retaining grooves are evenly distributed on the rotating shaft.
[0011] Furthermore, one end of the stop pin is clamped on the outer side of the connecting plate, and the other end of the stop pin is clamped on the inner side of the stop groove in the rotating shaft and the connecting plate.
[0012] Furthermore, an internal thread is provided on the inner side of the retaining groove, and an external thread is provided on the outer side of the other end of the retaining pin, and the internal thread matches the external thread.
[0013] Beneficial effects: 1. When the integrated wrench is in use, when it is necessary to install or disassemble the bolt, if the bolt is installed on one side of the equipment and there is an obstacle blocking the side of the equipment, and there is also an obstruction at the bottom or top of the bolt, first unscrew the stop pin, and then rotate the wrench head 90 degrees on the inside of the socket through the plug plate. The plug plate rotates on the inside of the slot in the connecting plate through the rotating shaft, and aligns the stop slot on the rotating shaft with the stop slot in the connecting plate, and then tightens the stop pin on the inside of the rotating shaft and the connecting plate through the cooperation of the internal thread and the external thread. At this time, the wrench head is perpendicular to the handle, and the bayonet is clamped on the outer side of the bolt. The handle is along the gap between the equipment and the obstacle, and passes over the obstacle facing the bolt. The wrench head can be rotated by turning the handle, thereby facilitating the installation and disassembly of the bolts blocked by obstacles and improving the adaptability of the equipment.
[0014] 2. When the integrated wrench is in use, when a large torque is required for the installation and removal of a bolt blocked by an obstacle, and a person cannot meet the torque required for the installation and removal of the bolt by simply turning the bent handle, the hexagonal socket in the sleeve is connected to the hexagonal socket wrench, and the hexagonal socket is driven to rotate by the hexagonal socket wrench, and then the sleeve drives the handle to rotate through the connecting block, thereby increasing the working force arm of the handle, and then increasing the torque of the wrench head on the bolt through the bayonet, so as to meet the torque required for the installation and removal of the bolt, and ensure the rapid removal of the bolt and the firm installation.
[0015] 3. The integrated wrench is reasonably designed and is efficient and convenient to use. It is suitable for installing and removing bolts. BRIEF DESCRIPTION OF THE DRAWINGS
