Detailed Description
The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the utility model provides an electric screwdriver's criticizing first conversion equipment, install motor output shaft 2 at main part 1 terminal surface including main part 1 and rotation, rotate in main part 1 and install conversion ring 3, install a plurality of flexible regulation poles 4 on the conversion ring 3, just flexible regulation pole 4 is kept away from the one end of conversion ring 3 is provided with prevents rotating wear groove 5, just prevent rotating wear groove 5 in the nested with motor output shaft 2 is centre of a circle radial slip's butt-joint lever 6, just prevent rotating wear groove 5 in install and be used for fixing the locking Assembly 7 of butt-joint lever 6, just being close to of butt-joint lever 6 motor output shaft 2 one end is rotated and is installed criticizing head 8, just install through interlock recess 9 motor output shaft 2 is last.
This implement neotype advantage lies in, through 4 installation butt rods 6 of telescopic adjusting rod, when making 4 elongations of telescopic adjusting rod, butt rod 6 will criticize first 8 radially to install on telescopic adjusting rod 4 with 2 position centers of motor output shaft, make butt rod 6 remove to predetermineeing the position through pressing down butt rod, thereby make criticizing first 8 and electric output shaft 2 and aim at, and criticize first 8 and directly install on butt rod 6 through the structure of miniature similar bearing, when making 4 contractions of telescopic adjusting rod, thereby make criticizing first 8 can follow motor output shaft 2 and move behind the positive fore-and-aft direction, until criticizing first 8 through interlock recess 9 nestification on motor output shaft 2, install promptly and accomplish.
The butt joint rod 6 through radial installation rotates the installation and criticizes head 8, and the radial slip of accessible one end makes criticizing head 8 aim at the dead ahead of motor output shaft 2 accurately, and this kind of mode becomes one section simple displacement with complicated butt joint process for the efficiency of aiming at is higher, aims at ground more accurately, and the operation is simpler.
Because the screwdriver head 8 needs to rotate along with the motor output shaft 2, the occlusion groove 9 is a regular hexagon groove generally, the cross section of the motor output shaft 2 is also a regular hexagon with the same size, and when the screwdriver head 8 is installed, the screwdriver head 8 only needs to be rotated through a bearing, so that the shape of the occlusion groove 9 on the screwdriver head 8 is matched with the motor output shaft 2.
Since the bits 8 and the docking rod 6 which are not used need to be attached to the main body 1 for storage, the length of the electric output shaft 2 needs to be greater than the whole thickness formed by the bits 8 and the docking rod 6, so that the bits 8 which are stored do not affect the bits 8 which are working.
Can also set up on main part 1 and deposit the recess, deposit butt joint pole 6 and batch head 8 to depositing in the recess through telescopic adjusting pole 4, further reduce the volume of batch head 8 of depositing, this kind of similar scheme is more, can realize the function of depositing of more saving space mode through telescopic adjusting pole 4.
As shown in fig. 3, the telescopic adjusting rod 4 includes an outer cylinder 401 fixedly mounted on the conversion ring 3, an inner cylinder 402 is slidably nested in the outer cylinder 401, and the rotation-preventing through groove 5 is provided on the inner cylinder 402. A fixed point clamping groove 403 is formed in the outer cylinder 401, a fixed point rod 404 is nested in the fixed point clamping groove 403 in a sliding mode, and the fixed point rod 404 is hinged to the inner cylinder 402.
The telescopic adjusting rod 4 mainly realizes the actions of moving the batch head 8 to the front of the motor output shaft 2 and embedding the batch head 8 on the motor output shaft 2, and accommodates and stores the unused batch head 8 and the butt joint rod 6; the sliding of the telescopic adjusting rod 4 is mainly realized by the outer cylinder 401 being nested on the inner cylinder 402 to move, the positioning of the telescopic adjusting rod 4 is mainly realized by moving the fixed point rod 404 hinged on the inner cylinder 402 to the concave part above the fixed point clamping groove 403, and the fixed point rod 404 is clamped by the concave part of the positioning clamping groove 403, so that the sliding of the inner cylinder 402 is limited.
As shown in fig. 4, the locking assembly 7 includes a sliding groove 701 disposed on a wall of the anti-rotation slot 5, and a sliding block 702 disposed on the butt rod 6 and nested in the sliding groove 701 to slide, the sliding block 702 is connected to a top end of the sliding groove 701 through a return spring 703, a sliding through hole 704 is disposed on one side of the anti-rotation slot 5, a damping blocking piece 705 is nested in the sliding through hole 704, and the damping blocking piece 705 extends into the sliding groove 701.
When the docking rod 6 is manually pressed, the sliding block 702 is nested and slides in the sliding groove 701, the return spring 703 is downwards extruded until the sliding block 702 moves to the position below the sliding through hole 704, the damping blocking piece 705 is nested in the sliding through hole 704, manual left and right operation is stopped, the sliding block 702 is relatively stably fixed below the damping blocking piece 705 under the action of the return spring 703, and therefore the docking rod 6 is displaced at a preset position, and the displacement length is controlled by the damping blocking piece 705, so that the displacement length is accurate.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
