The side wall of the main shaft shell 1, corresponding to ventilation area 59 is equipped at the position of motor 3, in the ventilation area
It is even that multiple ventholes are distributed with.
When the present invention uses, first screw wrenching tool of the selection containing required screw wrenching tool unit 16 turns
Wheel 6, and guarantee to push and pull the maximum stroke that lid 12 is located at rear end.
Then the screw wrenching tool runner 6 is placed on casing 5, and engages limit ball 47 with ball limiting slot 64
Limit, it is then again that vertical plate 48 and connecting plate 9 is fixed, while guaranteeing that transmission shaft 4 and axis hole A50 are rotatablely connected.
By rotating bolt tightening device runner 6, make to twist when the bolt of only required screw wrenching tool unit 16
Tight device storage through-hole 15 turns at position corresponding with screw wrenching tool cutting ferrule 7.
Then by that will push and pull lid 12 to being pushed forward, drive the strip groove 43 that pushes and pulls pipe 10 and push-pull rod 11 along casing 5 to
Be pushed forward into；When the postive stop baffle 33 of push-pull rod 11 draws baffle 71 to contact with the hook of required screw wrenching tool unit 16
When, push-pull rod 11 is temporarily blocked, and is pushed and pulled pipe 10 and then continued to push ahead in the case where push-and-pull lid 12 acts on；To push-pull rod 11
It is being moved backward for pushing and pulling pipe 10, so causing the convex column 35 of push-pull rod 11 along the strip through-hole of push-and-pull pipe 10
B32 is moved backward, to make the opposite push-and-pull pipe 10 of push-pull rod 11 also rotate while moving backward, when push-pull rod 11
When convex column 35 is moved to the strip through-hole rear end B32, the convex block A34 of push-pull rod 11 turns to the side of push-pull rod 11 at this time
Side, and the drag hook 40 of push-pull rod 11 protrudes into the hook pull ring slot 70 of screw wrenching tool unit 16.
Then screw wrenching tool unit 16 is driven under the continuing to press on of push-and-pull lid 12, through push-and-pull pipe 10 and push-pull rod 11
It moves forward, stretch out screw wrenching tool storage through-hole 15, until the body of rod card-tight part 67 and bolt of screw wrenching tool unit 16 are twisted
Tight 7 clamping of device cutting ferrule.
When the body of rod card-tight part 67 of screw wrenching tool unit 16 and when 7 clamping of screw wrenching tool cutting ferrule, bolt at this time
The hook pull ring slot 70 of tightening device is at the position between screw wrenching tool runner 6 and screw wrenching tool cutting ferrule 7, in addition push-pull rod
11 convex block A34 is just also just through push-pull rod limited block, and the front end face of the rear end face of convex block A34 and push-pull rod limited block
It contacts and resists.
The hand of spiral of bolt is finally screwed as needed, by the rotation direction of the selection motor 3 of forward-reverse switch 61, it will
Start button 8 can be screwed or be unscrewed to bolt after screw wrenching tool unit 16 is directed at bolt.
When needing in addition using other screw wrenching tool, it is necessary first to draw current screw wrenching tool unit 16
It is back in the screw wrenching tool storage through-hole 15 of screw wrenching tool runner 6.The operating process is as follows:
It is pulled back by the way that lid 12 will be pushed and pulled, push-and-pull pipe 10 is driven to draw back along the strip groove 43 of casing；At this time due to pushing away
The drag hook 11 of pull rod 11 hooks up to the hook pull ring slot 70 of screw wrenching tool unit 16, and the body of rod clamping of screw wrenching tool unit 16
Portion 67 and 7 clamping of screw wrenching tool cutting ferrule, cause push-pull rod 11 temporarily to fail to move backward, so push-pull rod 11 at this time is opposite
It is being moved forward for pushing and pulling pipe 10, so causing the convex column 35 of push-pull rod 11 along the strip through-hole B32 of push-and-pull pipe 10
It moves forward, to make the opposite push-and-pull pipe 10 of push-pull rod 11 also rotate while moving forward, with push-pull rod 11
Rotation, convex block A are separated with push-pull rod limited block；When the convex column 35 of push-pull rod 11 is moved to the strip through-hole front end B32,
The convex block A of push-pull rod 11 turns to the top of push-pull rod 11 at this time, convex block B39 turns to the side of push-pull rod 11.
Then screw wrenching tool unit 16 is driven under the pulling on of push-and-pull lid 12, through push-and-pull pipe 10 and push-pull rod 11
Overcome and moves backward with the frictional force of screw wrenching tool cutting ferrule 7, stored in through-hole 15 into screw wrenching tool.
When the sliding block 29 of push-and-pull pipe 10 is moved rearwardly into along the deep trouth 45 of strip groove 43 connection of deep trouth 45 Yu shallow slot 44
When place, sliding block 29 is blocked by the step facade that shallow slot 44 and 45 junction of deep trouth are formed；In pulling on for push-and-pull lid 12
Under, 29 facing sleeve 5 of sliding block of push-and-pull pipe 10 continues to move backward, to be moved rearwardly into along link slot 46 and current bar
In the shallow slot 44 of another adjacent strip groove 43 of slot 43.
When the sliding block 29 for pushing and pulling pipe 10 just left deep trouth 45, into lead-over groove 46 when, screw wrenching tool unit 16
The screw wrenching tool for just stretching out screw wrenching tool runner 6 in hook pull ring slot 70 backward stores through-hole 15；When the cunning of push-and-pull pipe 10
When block 29 is located at 46 position of lead-over groove, the convex block B39 of push-pull rod 11 is contacted with convex block C set by 1 inner wall of main shaft shell, item
Convex block B39 in shape through-hole A37 is blocked and be located in push-pull rod 11 by convex block C, and axial stock 38 is located at drag hook 40 and pushes away at this time
The distance in 11 axle center of pull rod is greater than the radius of postive stop baffle 33, and drag hook 40 is separated with hook pull ring slot 70 at this time, and casing 5 drives
Screw wrenching tool runner 6 rotates.
Enter and another adjacent bar shaped when the sliding block 29 of push-and-pull pipe 10 is moved rearwardly under the action of pushing and pulling lid 12
When in the shallow slot 44 of slot 43, casing 5, which drives screw wrenching tool runner 6 to turn to, twists screw wrenching tool cutting ferrule 7 and bolt
It is concentric right that screw wrenching tool before tight device runner 6 stores adjacent another screw wrenching tool storage through-hole 15 of through-hole 15
It answers.
If the screw wrenching tool unit 16 in the adjacent screw wrenching tool storage through-hole 15 is to need spiral shell to be used
If bolt tightening device unit 16, operated before can directly repeating using the operating method of screw wrenching tool unit 16.
If required screw wrenching tool unit 16 is still in the screw wrenching tool runner 6 but is not the adjacent spiral shell
If bolt tightening device stores the screw wrenching tool unit 16 in through-hole 15, above-mentioned related release screw wrenching tool unit can be repeated
16 and retract the method for screw wrenching tool unit 16, until required screw wrenching tool unit 16 is released；Can also directly it lead to
It crosses and can be manually rotated the screw wrenching tool storage drawing of through-hole 15 that screw wrenching tool runner 6 to storage has required screw wrenching tool unit 16
It is concentric corresponding with screw wrenching tool cutting ferrule 7, it is carried out before then repeating using the operating method of screw wrenching tool unit 16
Operation.
If required screw wrenching tool unit 16 is not in the screw wrenching tool runner 6, need vertical plate 48
It removes, then remove the screw wrenching tool runner 6 on casing 5, reselection contains the spiral shell of required screw wrenching tool unit 16
Bolt tightening device runner 6 is operated before repeating using operating method of the invention.
