Abstract
The utility model discloses a down-pressing type electric screw driver which comprises a screw driver shell and a main shaft installed in the screw driver shell. A screw driver head is fixedly connected at the front end of the main shaft, a motor is installed at the back end inside the screw driver shell, a reduction gear train is arranged between the motor and the main shaft, a microswitch which controls working of the motor is further arranged in the screw driver shell, an elastic piece is installed at the back end of the main shaft, and a feeler side which protrudes toward the microswitch side is arranged at the tail end of the elastic piece. After being arranged into the head portion of the screw driver, the screw driver head is pressed downward and drives the elastic piece to move upward together through the main shaft so as to enable the feeler side to touch the microswitch and thus to enable the motor to work. The main shaft is driven to rotate through the reduction gear train, and then the screw driver starts to work. The down-pressing type electric screw driver is compact in structure, convenient to operate, labor-saving, and applicable to the field of a screw driver.
Description
Technical field
The utility model relates to a kind of electric screw driver, particularly relates to a kind of electric screw driver of press-down type.
Background technology
Electric screw driver is saved the advantage of working time and labour intensity etc. because it is easy to operate, and is popular on market.
And existing electric screw driver is divided into two classes haply, wherein a class arranges proficiency by switch for the handle at screwdriver, after driver bit is positioned over screw head, presses this hand by switch with hand, can drive screwdriver work, get final product by switch and when quitting work, unclamp hand.The operation of this type of electric screw driver comparatively bothers, and use comparatively painstaking.Another kind of electric screw driver is provided with a microswitch between variable-speed gear system and motor or after the motor, place depression bar on the screwdriver main shaft again, is pressed onto microswitch by depression bar.After driver bit is positioned over screw head, press down gently, can by main shaft to depression bar again to microswitch, drive screwdriver work.This type of electric screw driver uses comparatively laborsaving, but its complex structure, thereby cause the electric screw driver volume larger, cost of manufacture is high.
The utility model content
For addressing the above problem, the utility model provides a kind of easy to operate and press-down type electric screw driver that structure is more compact.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of press-down type electric screw driver, comprise the screwdriver shell and be installed on the interior main shaft of screwdriver shell, the front end of main shaft is fixedly connected with driver bit, the rear end of screwdriver enclosure is equipped with motor, be provided with reducing gear train between motor and the main shaft, also be provided with the microswitch of control motor rotation in the screwdriver shell, the rear end of main shaft is equipped with shell fragment, and the tail end of shell fragment is provided with one and stretches to the feeler limit of microswitch side.
Be further used as the improvement of technical solutions of the utility model, the rear end at shell fragment on the main shaft is installed with collar.
Be further used as the improvement of technical solutions of the utility model, be provided with the main shaft mount pad in the screwdriver shell, be provided with axle sleeve between main shaft mount pad and main shaft, also be provided with a bearing along the slip of main shaft mount pad inwall on the main shaft, also be provided with the back-moving spring that leans at bearing and shaft room on the main shaft.
Be further used as the improvement of technical solutions of the utility model, the front end at bearing on the main shaft is provided with the shaft part ladder.
Be further used as the improvement of technical solutions of the utility model, the top of main shaft also is installed with a sealing ring along the slip of main shaft mount pad inwall.
The beneficial effects of the utility model: the electric screw driver of this press-down type is after inserting screw head with driver bit, driver bit is pressed down, driver bit moves upward together by main shaft band spring plate, so that microswitch is touched on the feeler limit, thereby triggering motor rotation, drive the main shaft rotation by reducing gear train, screwdriver is namely started working, and this electric screwdriver structure is compact and operate more convenient laborsaving.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model internal structure schematic diagram.
The specific embodiment
With reference to Fig. 1, the utility model is a kind of press-down type electric screw driver, comprise screwdriver shell 1 and be installed on main shaft 2 in the screwdriver shell 1, the front end of main shaft 2 is fixedly connected with driver bit 27, the rear end of screwdriver shell 1 inside is equipped with motor 3, is provided with reducing gear train 6 between motor 3 and the main shaft 2, also is provided with the microswitch 5 of control motor 3 runnings in the screwdriver shell 1, the rear end of main shaft 2 is equipped with shell fragment 4, and the tail end of shell fragment 4 is provided with one and stretches to the feeler limit 41 of microswitch 5 sides.
The electric screw driver of this press-down type is after inserting screw head with driver bit 27, driver bit 27 is pressed down, driver bit 27 moves upward together by main shaft 2 band spring plates 4, thereby trigger motor 3 runnings, drive main shaft 2 rotations by reducing gear train 6, screwdriver is namely started working, and this electric screwdriver structure is compact and operate more convenient laborsaving.
As the utility model preferred embodiment, be installed with collar 42 in the rear end of shell fragment 4 on the main shaft 2, main shaft 2 is provided with for the groove that collar 42 is installed, and collar 42 is fixedly mounted in the groove, can limit collar 42 and slide vertically, effectively fixation spring tab 4.
As the utility model preferred embodiment, be provided with main shaft mount pad 21 in the screwdriver shell 1,2 on main shaft mount pad 21 and main shaft are provided with axle sleeve 22, also be provided with a bearing 23 that slides along main shaft mount pad 21 inwalls on the main shaft 2, also be provided with the back-moving spring 24 that leans on 22 on bearing 23 and axle sleeve on the main shaft 2.
