[0023] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.
[0024] Example 1
[0025] Reference Figures 1 to 4 A schematic diagram of the overall structure of a position-adjustable quick-press screwdriver is provided, as shown below. Figure 1An adjustable quick-press screwdriver includes a housing 1, a disassembly / assembly mechanism 2 mounted on the housing 1, a movable mechanism 3 disposed within the housing 1, an adjustment mechanism 4 disposed within the housing 1, a screwdriver shank 5 mounted on the adjustment mechanism 4, and a guide mechanism 6 disposed within the housing 1. The movable mechanism 3 includes a fixed frame 303 disposed within the housing 1, a limit rod 302 movably mounted on the fixed frame 303, a first gear 305 movably mounted on the fixed frame 303 surrounding the screwdriver shank 5, and a fixed frame 302 at the top of the first gear 305. The second gear 304 is movably mounted on the 03. The first rack 306 is installed in the housing 1 at one end of the fixed frame 303, and the second rack 309 is installed in the housing 1 at the other end of the fixed frame 303. The first spring 307 is installed between the top of the fixed frame 303 and the disassembly and assembly mechanism 2. The user can hold the housing 1, place the knife bar 5 on the screw that needs to be installed and connected, and then press it. The movable mechanism 3 will press and rotate the screw to install it in the designated position for installation and connection work, which is convenient for personnel to use.
[0026] Specifically, two sets of second gears 304 are provided, located on both sides of the limiting rod 302. The two sets of second gears 304 mesh with the first rack 306 and the second rack 309 respectively, and both sets of second gears 304 mesh with the first gear 305. When the second gear 304 rotates, it will drive the first gear 305 to rotate through its meshing relationship. Because the first rack 306 and the second rack 309, which mesh with the two sets of second gears 304, are respectively located at both ends of the fixing frame 303, the second gear 304 contacts the first rack 306 and the second rack 309 respectively. During meshing, the two sets of second gears 304 rotate in opposite directions, thus driving the first gear 305 to rotate in one direction together when meshing with it. The first rack 306 and second rack 309 drive it synchronously in multiple directions to ensure stability during device adjustment. Two sets of first racks 306 and second racks 309 are provided, with the first racks 306 located on either side of one end of the first gear 305, and the second racks 309 located on either side of the other end of the first gear 305. The first racks 306 and second racks 309 located diagonally opposite each other constitute one working group, as shown in the attached diagram. Figure 2 The first gear 306 and the second gear 309 shown are in the first working state.
[0027] Furthermore, the second gear 304 passes through the fixed frame 303 and is fitted with a limiting block 308. The outer surfaces of the housing 1 surrounding the limiting block 308 are provided with limiting grooves 3010. During the up-and-down movement of the fixed frame 303, the limiting block 308 will slide synchronously within the limiting grooves 3010. This not only allows for limiting and guiding the fixed frame 303, but also allows users to easily and intuitively see the adjustment distance of the fixed frame 303, making it convenient for users.
[0028] Operating Procedure: The operator places the screw to be installed in the designated position, then places the tool bar 5 against the screw, and then presses down on the device. The first spring 307 contracts synchronously, pressing the tool bar 5 into the housing 1. As the tool bar 5 moves into the housing 1, it drives the fixing bracket 303 to move synchronously. When the fixing bracket 303 moves upward, it rotates synchronously through the contact meshing of the second gear 304 with the first rack 306 and the second rack 309 respectively. This rotation, in turn, drives the first gear 305 to rotate synchronously. The rotation of the first gear 305 drives the tool bar 5 to rotate synchronously, thus applying pressure to the bolt to be installed when the operator presses down on the device. While applying pressure, the screwdriver 5 can be automatically rotated to install the screw onto the designated structure. After the screw is installed, the device is lifted, and the first spring 307 will push the fixing bracket 303 back to the lowest point inside the housing 1 due to the disappearance of resistance, so as to facilitate the operator's subsequent use. When using the device, simply hold the device and apply downward pressure to the screw to easily rotate and install the screw onto the external structure. There is no need to rotate the screwdriver to drive the screw to rotate synchronously while applying downward pressure. The operation is simple, improves the screw installation speed, saves time and effort, reduces the workload of the operator, and is convenient for the operator to use.
[0029] Example 2
[0030] Reference Figures 1 to 4 This embodiment differs from the first embodiment in that it also includes a disassembly and assembly mechanism 2, comprising a first fixing plate 201 disposed on the top of the housing 1 and a second fixing plate 202 disposed on the bottom of the housing 1; the bottom of the first fixing plate 201 is fixedly connected to the first spring 307, and a limiting seat 301 is installed between the first spring 307 and the fixing frame 303, wherein the first fixing plate 201 and the second fixing plate 202 perform sealing and protection work on the top and bottom of the housing 1, and the limiting seat 301 performs limiting work on the position of the first spring 307, improving the stability of the device during use, and the limiting seat 301 has a damping effect to prevent the situation from not working due to excessive flexibility.
[0031] Specifically, the adjustment mechanism 4 includes a shaft 404 disposed within the housing 1. A movable block 403 is rotatably mounted on the periphery of the shaft 404, and an adjustment rod 402 is mounted on the movable block 403. Both the first fixed plate 201 and the second fixed plate 202 are provided with slots 401. The user can rotate the movable block 403 by moving the adjustment rod 402, thereby pushing and moving the first rack 306 and the second rack 309 through the movable block 403.
[0032] Furthermore, the adjustment mechanism 4 is provided in two sets, which correspond to the first fixed plate 201 and the second fixed plate 202 respectively. Each set of adjustment mechanism 4 is provided with four adjustment rods 402. The housings at the first fixed plate 201 and the second fixed plate 202 are respectively provided with four adjustment rods 402. The four adjustment rods 402 are divided into two groups, which correspond to the first rack 306 and the second rack 309 located diagonally.
[0033] Furthermore, the first fixed plate 201 and the second fixed plate 202 are each provided with four sets of slots 401. The four sets of slots 401 are respectively adapted to four adjusting rods 402. When the operator screws the adjusting rod 402 into the corresponding slot 401, it indicates that the first rack 306 and the second rack 309 have been pushed and moved by the movable block 403.
[0034] Specifically, the guide mechanism 6 includes a fixed rod 604 disposed within the housing 1. Fixed blocks 601 are installed in both the first rack 306 and the second rack 309 surrounding the fixed rod 604. Movable grooves 603 are provided in the fixed blocks 601 surrounding the fixed rod 604. A second spring 602 is installed between the fixed blocks 601 and the fixed rod 604. Fixed set screws are provided on the first rack 306 and the second rack 309 to prevent the fixed blocks 601 from rotating. The fixed blocks 601 limit the positions of the first rack 306 and the second rack 309, preventing them from shifting left or right during operation and dislodging from the first rack 306 or the second rack 309, thus affecting their use.
[0035] The rest of the structure is the same as in Example 1.
[0036] Operation process: In the initial state, the first spring 307 will push the fixing bracket 303 to the bottom of the housing 1 due to its own elasticity. In the first working state and the second working state, the movable groove 603 in the fixing block 601 of the first rack 306 and the second rack 309 are both / \ shaped. The user can move the lever 402 located at the top of the device to make it drive the movable block 403 to squeeze the second rack 309, so that it is disengaged from the second rack 306. Then, by moving the lever 402 located at the bottom of the device, it will drive the movable block 403 to lock the first rack 306, so that the first rack 306 cannot move by the movable groove 603, so that it is always engaged with the second gear 304, thereby moving the tool bar 5 upward. The tool holder 5 rotates clockwise when moving upwards and counterclockwise when descending. It can also switch the states of the first rack 306 and the second rack 309, causing the tool holder 5 to rotate clockwise when moving upwards and counterclockwise when descending. The user can move the actuating lever 402 at the top of the first rack 306 and the second rack 309 in the second working state, causing it to rotate the movable block 403. This compresses the racks in the second working state, causing them to move diagonally downwards along the shaft 404 via the movable groove 603. This disengages the first rack 306 from the second rack 309 and the second gear 304, disengaging them. When the user presses the tool holder 5 against the bolt and lowers the device, causing the fixing frame 303 to move upwards, the second gear 304 will... By engaging with the first rack 306 and the second rack 309 in the first working state and rotating clockwise, after the device is released, the first spring 307 will push the fixing bracket 303 back to the lowest position inside the housing 1 due to its own elasticity, thereby driving the tool bar 5 to move upward. At this time, when the second gear 304 contacts the first rack 306 and the second rack 309 in the first working state during the descent, it will push them to move diagonally downward on the shaft 404 according to the orientation of the movable groove 603. After moving one step, the rack in the first working state will be pushed back to its original position by the second spring 602 and engage with the second gear 304. By repeating the above operation, the second gear 304 will always maintain engagement with the rack in the first working state during the descent without engaging with it to rotate, thereby realizing the tool bar The tool holder 5 rotates clockwise when rising and remains stationary when descending. The operator can switch between a first and second working state, enabling the tool holder 5 to rotate counter-clockwise when rising and remain stationary when descending. The operator can rotate the fixing block 601 as needed, allowing it to rotate within the first rack 306 and second rack 309. In both the first and second working states, the movable groove 603 within the fixing block 601 is of the / / type. When the operator presses the tool holder 5 against the bolt and lowers the device, causing the fixing frame 303 to move upwards, the second gear 309 will mesh with the first rack 306 in the first working state, pushing the second rack 309 to move along the movable groove 603.When the first spring 307 pushes the fixed frame 303 downward, the second gear 309 meshes with the second rack 309 in the first working state, pushing the first rack 309 to move via the movable groove 603, so that the tool holder 5 rotates clockwise when rising and counterclockwise when falling. Simultaneously, the first working state and the second working state can be switched, so that the tool holder 5 rotates counterclockwise when rising and clockwise when falling. At the same time, the user can move the lever 402 on the second rack 309 in the first working state and the first rack 306 in the second working state to drive... The movable block 403 pushes the tool holder 5 to disengage from the second gear 304, causing the second gear 304 to engage with the first rack 306 in the first working state and disengage from the second rack 309 in the second working state when the tool holder 5 moves upward. When the tool holder 5 moves downward, the second gear 304 engages with the second gear 309 in the second working state and disengages from the first rack 306 in the first working state. This causes the tool holder 5 to rotate clockwise when moving upward and downward. Simultaneously, the above can be switched so that the tool holder 5 rotates counterclockwise when moving upward and downward.
