Detailed description of the invention
In conjunction with accompanying drawing, this utility model is described in further detail.
In description of the present utility model, it is to be understood that term " on ", " in ", D score, "front", "rear", " left ",
The indicating position such as " right ", " interior ", " outward " or position relationship are based on orientation shown in the drawings or position relationship, are for the ease of retouching
State rather than indicate or imply the device of indication or element must have specific orientation, with specific azimuth configuration and operation,
Therefore it is not intended that to restriction of the present utility model.
Fig. 1 to Fig. 7 shows a kind of embodiment of the present utility model, and it includes handle 1, support bar 2, expansion link 3 and
Head 4；The right-hand member of handle 1 is connected with support bar 2, the right-hand member of this support bar 2 and the fixing connection of the first adapter sleeve 5.Expansion link 3
Left end be socketed in the first adapter sleeve 5.The right-hand member of expansion link 3 and the second fixing connection of adapter sleeve 6, the right side of the second adapter sleeve 6
End is connected with head 4, and head 4 and the second adapter sleeve 6 are for detachably installing and being socketed in the second adapter sleeve 6.Second connects
One end of set 6 is in addition to being connected with expansion link 3, it is also possible to be directly connected with handle 1, it is also possible to by support bar 2 and handle 1 phase
Connect.
First adapter sleeve 5 and the second adapter sleeve 6 right-hand member are both provided with locking device.This locking device includes being arranged on first
Open slot 13 on adapter sleeve 5 and the second adapter sleeve 6, the both sides of this open slot 13 are respectively provided with spanner seat 11 and nut seat 12.
Open slot 13 is axially arranged and extends to the first adapter sleeve 5 and right-hand member of the second adapter sleeve 6.Spanner 14 is arranged on spanner seat 11
On, one end of spanner 14 arranges opening 28, arranges pin button 15 and bolt 16 in this opening 28, bolt 16 sequentially pass through spanner 14,
Pin button 15, spanner seat 11 are connected with nut seat 12.Bolt 16 is preferably bolt 16 and inserted num seat with the connection of nut seat 12
The nut 17 of 12 connects.Spanner 14 can rotate around pin button 15, and spanner 14 to arrange one end of pin button 15 be the inclined of band salient angle 20
Heart circle.
Being additionally provided with spacing raised line 19 on spanner seat 11, this spacing raised line 19 matches with salient angle 20, when salient angle 20 rotates
To stopping operating at spacing raised line 19, preventing spanner from breaking into two with one's hands, angle is excessive that spanner is caused damage.It is positioned at spanner on spanner seat 11
Arranging protruding 18 between 14 and bolt 16, this projection 18 is set to square.Arranging protruding 18 is possible to prevent spanner to external rotation.Pull
The outside of hands seat 11 arranges baffle plate 21, and this baffle plate 21 is also possible to prevent spanner to external rotation.Arrange a plurality of with the on spanner seat 11
The reinforcement 22 that one adapter sleeve and the second adapter sleeve connect, it is strong that reinforcement is used for strengthening the connection between spanner seat and adapter sleeve
Degree.
Second adapter sleeve 6 both sides respectively arrange a square hole 23, and head 4 arranges two buttons near one end of the second adapter sleeve 6
24, two button 24 springs 25 connect, and two buttons 24 can buckle in square hole 23.Button 24 is set to inclined upper surface, leans on
Nearly second adapter sleeve side is relatively low, and other side is higher.Button is set to inclination, when head inserts the second adapter sleeve, presses
Button can shrink and easily buckle in square hole automatically.When head inserts the second adapter sleeve, button buckles in square hole, prevents head from existing
Coming off during use, the one end being connected with head by the second adapter sleeve with locking device the most again is locked, makes head with adapter sleeve even
Connect more firm；When needing to pull down head, unclamp spanner, press the button and head is extracted.
Head 4 arranges contact pin 26 on the top end face of the second adapter sleeve 6, when head inserts the second adapter sleeve, and contact pin
Electrically connected with battery bag by the plug being arranged in the second adapter sleeve.Top end face also sets up projection 27 near edge, and this is convex
The height of block is more than or equal to the height of contact pin.Projection is used for protecting contact pin, when head falls, prevents contact pin from fractureing.
Second adapter sleeve 6 and head 4 are connected with each other the cross section of part and are set to the irregularly shaped of not rounded, as it is shown on figure 3,
It is preferably arranged to water-drop-shaped.Second adapter sleeve and head are connected with each other the cross section of part and are set to irregularly shaped, can limit machine
Head direction of insertion, prevents head electrode anti-inserted.
Battery bag 7 is set on handle 1.Arranging battery bag 7 can make garden instrument at the local work away from supply socket.
Making a detailed explanation the locking of spanner and unclamping in conjunction with Fig. 6, Fig. 7, O point is the central point of pin button, spanner
Can rotate around O point.The point that C point contacts with spanner seat when opening for spanner, D point contacts with spanner seat when locking for spanner
Point.Spanner is set to off-centre operation, is E point from O point farthest.In D point and C point, D point is close to E point.So, OE ＞ OD ＞ OC.
When spanner is locked, spanner rotates counterclockwise, and the trend of the point that off-centre operation periphery contacts with spanner seat is C to D, from C point to E point
Time, wrench seat presses gradually downward, lock increasingly tighter, to the tightest during E point；Affected by elastic force when crossing E point and be rapidly converting to D point, this
Time, the other end of spanner contacts with the reinforcement on spanner seat and stops operating.Owing to D point is closer with E point, although ratio is at E point
Time degree of blocking reduced, but the most enough lock expansion link.Spanner unclamps contrary with locking, and spanner rotates clockwise, eccentric
The trend of the point that circle periphery contacts with spanner seat is D to C, can quickly rotate to C point after E point broken by spanner, when salient angle contacts
During to spacing raised line, stop operating.
Locking device of the present utility model uses off-centre operation spanner, can be achieved with locking by moving spanner, and locking is convenient.
Locking device is additionally provided with that to prevent spanner from breaking angle into two with one's hands excessive, and spanner causes the stopping means of damage.It is additionally provided with and prevents from pulling
Hands is to the anti-twisting equipment of external rotation.Head of the present utility model, in addition to locking device is locked, also buckles with spring button, makes machine
Head is more firmly mounted, and convenient dismounting.
