Embodiment
The present invention is further illustrated below in conjunction with the accompanying drawings.
Felt relieved compound clamping device as shown in figure 1, the present invention provides a kind of pushing tow, including pedestal 1, axle sleeve 2, push away seat, be solid
The clamping jaw 5 that reservation 3, tapered shaft 4 and three are circumferentially uniformly arranged, wherein, pedestal 1 is provided with vertical through hole 6, and axle sleeve 2 is fixed on vertical
In clear opening 6, the T-shaped structure that seat is made up of horizontal segment 7 and vertical section 8, vertical section 8 and the axial sliding fit of axle sleeve 2 are pushed away, is hung down
Straight section 8 is provided with longitudinal direction and is provided with through hole 9, and through hole 9 penetrates with horizontally disposed short-bore 10 on horizontal segment 7, and tapered shaft 4 is vertical with through hole 9
To being slidably matched, clamping jaw 5 is slidably matched with the level of short-bore 10, and the inner lozenges 42 corresponding with the upper end of tapered shaft 4 of clamping jaw 5 is slided
Dynamic to coordinate, clamping jaw 5 is provided with steady pin 11, horizontal between steady pin 11 and horizontal segment 7 to be provided with compression spring 3 12, horizontal segment 7
Upper surface be provided with and be used to close the cover plate 13 of through hole 9, the inner side of cover plate 13 fixes restricted steady pin 11 and retracts excessive limit
Position plate 14；The lower end of tapered shaft 4 is provided with gag lever post 15, and compression spring 1 is arranged with gag lever post 15, compression spring 1
Upper end is fixedly connected with tapered shaft 4, and lower end is fixedly connected with fixed seat 3；Fixed seat 3 is that top is provided with axial hole 34 and lateral wall
Cover body structure provided with step 1 Yu step 2 32, cover body middle part are limit chamber 33, the lower end of gag lever post 15 and fixed seat 3
The axial sliding fit of axial hole 34, the end that the gag lever post 15 stretches into limit chamber 33 is provided with limited block 17, the lower end of vertical section 8
Longitudinal section is the L-shaped structure with horizontal bench 81 Yu longitudinal sleeve 82, and longitudinal sleeve 82 is sheathed on the upper end of fixed seat 3 and should
