Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment：
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：Controllable push of one kind screws electric screw
Knife, including screwdriver 1, casing 2 and handle 3, the handle 3 are connected with casing 2, and the screwdriver 1 is connected by holding screw 4
Be connected to power transmission shaft 5, the power transmission shaft 5 is connected with brake apparatus 6, the brake apparatus 6 includes overcoat 7 and clutch 8, it is described from
Clutch 8 is arranged on overcoat 7, is provided with the clutch 8 on fulcrum 9, the fulcrum 9 and is provided with the first spring 10, described
First spring 10 is connected with the first steel ball 11, and the fulcrum 9 is connected with lower slip clutch 12, and lower slip clutch 12 passes through partition
13 are connected with slip clutch 14, the partition 13 and are provided with the second steel ball 15, and the upper slip clutch 14 connects intentionally axle
16, the both sides of the heart axle 16 are mounted on spring assembly 17, and heart axle 16 is connected with flexible axle 18, and the spring assembly 17 passes through
Packing ring 19 is connected with nut 20, and the nut 20 is connected with band moving axis 21, and the both sides of the flexible axle 18 are mounted on sliding ring 22.
Preferably, the 3rd steel ball 23 is installed on the sliding ring 22；The spring assembly 17 is made up of some springs；
The heart axle 16 and flexible axle 18 are orthogonal；The handle 3 is provided with switch 24.
Specifically used mode and advantage：The electric screw driver, presses switch when using, flexible axle is driven by motor,
Rotated again by flexible axle and be transmitted to band moving axis, heart axle is then transmitted to by band moving axis, constantly positive and negative rotation.Twist screw when, lightly
Screwdriver is sunk, and the first spring and the first steel ball stress are pushed, and clutch is engaged with lower slip clutch, screw is down twisted,
