Problems solved by technology

[0002] The fastening of the screw requires a certain operating space on the screw head, that is, the length of the screwdriver and the handshake space of the screwdriver handle are required to achieve the purpose of holding the screwdriver handle to rotate the fastening screw. However, in some small tables, semi-enclosed spaces To realize the installation of screw fasteners, there is a narrow space above the screw head, the space size is often smaller than the length of the screwdriver, and obstacles are on the upper part of the screw, the screwdriver cannot be aligned vertically with the screw head, and the purpose of holding the screwdriver handle to rotate the fastening screw cannot be achieved

At present, three methods are used to solve this problem: one is to transform the existing screwdriver and process the screwdriver blade into Type, using the corner to avoid obstacles, to achieve the purpose of fastening the screw, the disadvantages of this method are: 1, after the transformation of the two parallel screws perpendicular to the screw head Type of screwdriver, the rod at the blade, because the fastening screw needs a force from the blade of the screwdriver to the screw head, so that the screw can be tightened, and the screw cannot be tightened only by the force of rotation. The downward pressure of the handle end cannot be fully transmitted to the screwdriver at the corner, so the purpose of complete tightening cannot be achieved; 2. The 360-degree rotation angle of the slotted screw during the rotation process, due to the narrow space and obst...

Example Embodiment

[0020]By the followingFigure 1-2An embodiment of the present invention will be described, thereby clarifying, integrally depicted, as described herein is merely, not all of the embodiments of the invention.

[0021]In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "post", "left", "right", "top", "bottom", "inside", " The orientation or positional relationship of the instructions such as "is based on the orientation or positional relationship shown in the drawings, which is merely description of the present invention and simplified description, rather than indicating or implying that the device or component must have a specific direction. Specific orientation construction and operation, it is not understood to limit the limitations of the invention.

[0022]Fastening aids for small desktop semi-closed space screws, such asfigure 1 As shown, including the case 1, the casing 1 rotates to mount the driven rod 2 provided with the upper and lower ends, and the front portion of the driven rod 2 and the distal end of the screw head surface, wherein However, the recess can be a one or cross or internal hexagonal, and the driven rod 2 is mounted on the box 1, which can not only be achieved by the bearing or the intermediate sleeve, but can also be outside the driven rod. A circular plate is provided on the circumferential wall, and the driven rod 2 adapted to the casing 1 is positioned, thereby achieving the rotation of the driven rod 2, wherein the driven rod between the two circle plates is wrinkled. The fixed projection is convenient for the slave wheel 6, and the interleave shaft rotating transmission of the driven rod 2 is provided in the casing 1 and connected to the driven rod 2, the stagne shaft rotating transmission. The other end projects out of the casing 1 and is rotated by the rotary shaft rotating transmission of the interleaved axis rotation transmission with the end fitted to the end portion, and the specific, the interleaved shaft rotating transmission is specifically structured:

[0023]The interleaved shaft rotary transmission includes a drive rod 4 that is rotatably mounted on the casing 1, a movable bevel gear 5 and a driven umbrella gear 6 in the casing 1, the active rod 4 and the active umbrella gear 5 The fixed connection and the active umbrella gear 5 are engaged with the driven umbrella gear 6 fixed to the driven rod 2, and the active rod 4 is connected to the rotary drive member; specifically, the active umbrella gear 5 and the driven The umbrella gear 6 is fixed to the active rod 4 and the driven rod 2, respectively, by fastening screws 8.

[0024]The interleand shaft rotating transmission can also employ the following structure: the interlenerable shaft rotary transmission uses a worm gear mechanism, the worm and the driven rod 2 vertically and rotates on the casing 1 and the other end of the worm projects out of the box 1. Set and connected to the rotary drive, the chormhing is fixed to the driven rod 2 and engage the worm.

[0025]The rotary drive is a screwdriver 7, the screwdriver 7 is adapted to a recess is attached to the end of the interleaved shaft rotary transmission; specifically, the rotary drive is in addition to the above structure, and can be rotated to the interleaved shaft. The other end of the transmission is fixedly connected.

[0026]In the above structure, by rotating the lower end portion and the recess adapted to the uneven end surface of the screw head surface on the casing 1, the interleaved shaft rotation transmission of the driven rod 2 is disposed on the casing 1. The device is rotated by the rotary drive member that is adapted to the interleaved shaft rotary transmission transmission, which provides a rotation basis for the screw; from the height adjustable mounted to the driving member 3 to the power of the boom 3, After the mushroom, the screw is supplied downward, and the fastening of the screw in semi-closed space is achieved.

[0027]In order to provide a downward pressure to the rotating driven rod 2, the fastening of the fastening screw acts, and therefore, the upper end height adjustable mounting of the driven rod 2 is provided to provide the driven bar 2 Pressing power of the pressure 3; the specific structure of the booster 3 is as follows: The baffle member 3 includes a screw 3-1 and a base 3-2 disposed on the upper end of the screw 3-1, the screw 3-1 and the driven The threaded holes in the upper side of the upper end of the rod 2 are adapted to achieve the adjustment of the screw 3-1 projecting the driven rod 2 height by the rotary screw 3-1, and the base 3-2 is fixed to the outer wall of the screw 3- 1 Vertically and show the handle rod 3-3 of a glyph distribution, and the handle rod 3-3 is fixed to the handle 3-4; specifically, the base 3-2 lower ends are fixed to the outer wall of the nut 3-5 And the inner end of the handle 3-3 is threaded with the nut 3-5.

[0028]When used, first in the corresponding hole to be fastened, then place the driven rod 2 vertically on the bottom of the screw, if it is not possible, it can be adjusted through the handle 3-4 to adjust the height of the power supply 3. , The screw 3-1 is rotated into the inside of the driven rod 2 to release the space, and the driven rod 2 is placed vertically on the recess to be fastened to the screw, the adjustment screw 3-1 makes the pedestal 3-2 to hold to stay On the bottom surface of the structure above the screw head, the rotation belt is driven to pass the pressure on the drive rod 2 to the head to be fastened, and the screwdriver 7 is held, so that the screwdriver 7 align the recess of the other end of the active rod 5. After the rotation of the screwdriver 7 counterclockwise, the active rod 4 causes the driven rod 2 by the active gear 5 and the driven gear 6 to rotate clockwise, the driven rod 2 clockwise rotates the needle rotation to rotate the screw, to be tailored Under the action of the rotational force of the driven rod 2, it is convenient and convenient, and convenient, convenient, and conveniently realizes the fastening screw fixation.

[0029]In the present invention, the driven rod 2 is topped onto the head to be fastened to be fastened, and the other side base 3-1 is provided with a reaction force, and the screwdriver 7 is rotated counterclockwise. The driven rod 2, the casing 1 and the active rod 4 are as a whole, while slow down, and can be moved in a clockwise direction to rotate, convenient, easy, and quickly improve the work efficiency of debugging and maintenance.
