Fig. 3 is I place enlarged drawing in Fig. 1.
Description of reference numerals: fixed cover connecting rod, the upper fixed cover connecting rod of 12-, 13-square nut, the interior hexagonal holding screw of 14-flush end, 15-ball, 16-Compress Spring, 17-dovetail groove, 18-dovetail projection under fixed cover, 11-under dovetail tightening piece, the interchangeable outer dovetail tightening piece of 5-, 6-flat-bed machine screw, 7-tensioner brake rubber block, the upper fixed cover of 8-, 9-pull bar, 10-in 1-lifting bolt, the upper movable sleeve of 2-, 3-movable sleeve connecting rod, 4-are fixing.
Embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises hexagonal holding screw 14, ball 15 and Compress Spring 16 in lifting bolt 1, upper movable sleeve 2, movable sleeve connecting rod 3, fixing interior dovetail tightening piece 4, interchangeable outer dovetail tightening piece 5, tensioner brake rubber block 7, upper fixed cover 8, pull bar 9, lower fixed cover 10, lower fixed cover connecting rod 11, upper fixed cover connecting rod 12, flush end.
Described lifting bolt 1 is threaded connection pull bar 9, the upper movable sleeve 2 that is slidably installed on pull bar 9, and upper movable sleeve 2 can slide up and down on pull bar 9.On described upper movable sleeve 2, be bolted three movable sleeve connecting rods 3, the other end of movable sleeve connecting rod 3 is bolted the upper end of fixing interior dovetail tightening piece 4.
Described pull bar 9 lower ends connect fixed cover 8 and lower fixed cover 10 successively, are bolted three upper fixed cover connecting rods 12 on upper fixed cover 8, and the other end of upper fixed cover connecting rod 12 is bolted the upper end of fixing interior dovetail tightening piece 4.On lower fixed cover 10, be bolted three lower fixed cover connecting rods 11, the other end of lower fixed cover connecting rod 11 is bolted the lower end of fixing interior dovetail tightening piece 4.
Described fixing interior dovetail tightening piece 4 is provided with dovetail groove 17, and interchangeable outer dovetail tightening piece 5 is provided with dovetail projection 18, and the dovetail projection 18 of interchangeable outer dovetail tightening piece 5 embeds in the dovetail groove 17 of fixing interior dovetail tightening piece 4.In described dovetail projection 18, be threaded connection hexagonal holding screw 14 in flush end, in flush end, hexagonal holding screw 14 is fastening by square nut 13.In described flush end, on hexagonal holding screw 14, cover has Compress Spring 16, and the front end of Compress Spring 16 is provided with ball 15, and the fore-end of ball 15 is exposed at outside dovetail projection 18 and contacts with dovetail groove 17.Interchangeable outer dovetail tightening piece 5 by ball 15 can be in fixing slip in the dovetail groove 17 of dovetail tightening piece 4.
