Specific embodiment
The technical solution of this patent is described in more detail With reference to embodiment：
- 3 are please referred to Fig.1, a kind of hand-held machine work holder, including carrying axle 1,1 side wall of carrying axle is equipped with
Several jacks 15, are arranged with regulating sleeve 3 in carrying axle 1, and 3 side wall of regulating sleeve offers through-hole 22, activity in through-hole 22
Plug pin 23 is equipped with, 23 one end of plug pin is extend into jack 15, and 23 other end of plug pin is installed with pulling block 16, the plug pin 23
On be arranged with limit spring 24,3 lower end of regulating sleeve is installed with vertical fixed plate 20 vertically, in vertical fixed plate 20
It laterally wears and is fixed with screw shell 19,19 internal thread of screw shell, which is worn, is connected with screw 18, and 18 right end of screw is fixedly mounted
There is platen 17,18 left end of screw is installed with runner 21；Transverse sliding is arranged with sliding sleeve 12 in the carrying axle 1；It is described
12 lower end of sliding sleeve is installed with pressing plate 13 vertically；1 right end of carrying axle is installed with baffle 11, is arranged in carrying axle 1
There is resetting spring 10,10 left end of resetting spring is fixed on sliding sleeve 12, and 10 right end of resetting spring is fixed on 11 left side wall of baffle；Institute
It states 1 left upper end of carrying axle and is installed with the first hinged-support 2,12 upper end of sliding sleeve is installed with third hinged-support 9, and first is hinged
Rotary type is equipped with pull rod 4 on seat 2, and 4 upper end level of pull rod is installed with holding rod 5, interior install is fixed on 5 right side wall of holding rod
There is the second hinged-support 8, connecting rod 7 is hinged between the second hinged-support 8 and third hinged-support 9, passes through screw thread outside the holding rod 5
Connector sleeve is equipped with extension socket 6.
The present invention operation principle and application method be：
By pulling pulling block 16 that plug pin 23 is driven to be detached with jack 15, slidable adjustment sleeve 3 carries out position adjusting, limit spring 24
Restoring force by pulling block 16 drive plug pin 23 be inserted into the jack 15 of suitable position in carrying axle 1, at this time realize sleeve 3 with
The preliminary adjusting of distance between sliding sleeve 12；When needing clamping dimension or the larger mechanical workpieces of width, adjust increase sleeve 3 with it is sliding
The distance of set 12 when needing clamping dimension or the smaller mechanical workpieces of width, adjusts the distance for reducing sleeve 3 and sliding sleeve 12；Turn
Turn wheel 21 drives screw 18 to rotate, and the precession to the right of screw 18 drives platen 17 to move right, at this time platen 17 and pressing plate 13 it
Between distance further reduce, rotate backward runner 21, between platen 17 and pressing plate 13 distance increase, can be real by rotating wheel 21
Now platen 17 and the spacing of pressing plate 13 are further adjusted, facilitate the various sizes of mechanical workpieces of clamping；6 band of hand-held extension socket
The platen 17 and pressing plate 13 for moving the present invention are placed in the mechanical workpieces both sides to be clamped, and lift extension socket 6, extension socket upwards
6 drive pull rods 4 rotate counterclockwise, and pull rod 4 pulls sliding sleeve 12 to be slided to the left along carrying axle 1, and 10 deformation of resetting spring at this time is stretched
Long, carrying axle 1 is moved to the left with dynamic pressure plate 13, and mechanical workpieces are gripped by platen 17 and pressing plate 13 at this time, are continued up and are carried
Extension socket 6 is drawn, mechanical workpieces are in vacant state, the frictional force between the gravity and mechanical workpieces of mechanical workpieces and convex block 14
Balance, the gravity of mechanical workpieces have carrying axle 1 downward pulling force simultaneously, which causes between pull rod 4 and carrying axle 1
Angle increases, i.e., pull rod 4 rotates counterclockwise certain angle, and pull rod 4 drives sliding sleeve 12 to move to left by connecting rod 7, and then realizes pressure
Disk 17 and pressing plate 13 are to the clamp pressure of mechanical workpieces bigger, and the frictional force increasing between mechanical workpieces and convex block 14, machinery is more
Add and more stablize.The short-haul operation to mechanical workpieces can be realized in the mobile present invention；After mechanical workpieces are transported to specified region,
After 13 bottom surface of pressing plate contacts ground or workpiece placement station, extension socket 6, the spacing of regulating sleeve 3 and sliding sleeve 12 are pushed
From increase, platen 17 increases with 13 spacing of pressing plate, realizes the unloading to mechanical workpieces.Coefficient of elasticity can be selected slightly in resetting spring 10
Small spring is primarily served to the pulling reset response to the right of sliding sleeve 12 when unloading workpiece, easy to loading and unloading, easy to operate, is helped
In raising piece-holder handling efficiency；Rotation extension socket 6 extends to the right with respect to holding rod 5 can be to the gripping length of holding rod 5
Carry out extension extension, convenient for users to gripping, the convenient use to the present invention.
It is obvious to a person skilled in the art that the present invention is not limited to the details of above-mentioned exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
