7, described turning cylinder forms outrigger shaft portion 83 through the first described panel 11, this outrigger shaft portion 83 is connected with resetting means, thus, after hold down gag is unlocked, turning cylinder can rotate, namely outrigger shaft portion 83 also can rotate, now reset push rod 170 automatically can promote the first connection strap 140 under the effect of the second spring 160, and the first connection strap 140 can drive turning cylinder to rotate by the transmission of the second connection strap 150, and then make pivoted arm 81 forward initial position to, realize the reset of hold down gag.
8, being elevated axle sleeve 50 is fixedly connected on described Connection Block 60 by connecting axle 190, and on connecting axle 190, cover has pulley 200, and elevating bracket 210 is provided with the first inclined plane 211, first inclined plane 211 matched with described pulley 200 and tilts towards described snap fit position.Thus, when pulling handle 70 to rotate, the pulley 200 of connecting axle 190 can slide along the first described inclined plane 211, because the first inclined plane 211 tilts towards described snap fit position, and the position at workpiece 320 crimp 321 place just, the position of snap fit position, then under the effect of the first inclined plane 211, lifting axle sleeve 50 moves together with in connecting axle 190 meeting, and then makes chuck 40 moves and cross the crimp 321 of workpiece 320.This vibrational power flow makes chuck 40 can be elevated according to the track preset.
9, be elevated conversion equipment comprise rotate hand 230, ring portion 240, linking arm 250 and cushion block 260, rotating hand is connected to 230 and linking arm 250 in described ring portion 240, ring portion 240 fixed cover is located on described central shaft 20, and described cushion block 260 is located on linking arm 250.Because scroll spring 360 is different, the specification of workpiece 320 also may be different, the height of the crimp 321 of workpiece 320 also can be different, thus, pull with hand and rotate hand 230, linking arm 250 is made to follow rotation, the then leading section of cushion block 260 meeting jack-up elevating bracket 210, the gradient of above-mentioned first inclined plane 211 then can change, under this kind of situation, the height that chuck 40 can rise is higher, namely can cross highly higher crimp 321, realizes scroll springs 360 different for specification to be installed on the corresponding workpiece 320 of specification.Therefore, described scroll spring 360 can realize the installation of the scroll spring 360 to different size.
10, manual hoisting device comprises lifting hand lever 270, first support arm 280, lifting ring 290, second support arm 300 and bearing 310, and described lifting ring 290 is between described lifting axle sleeve 50 and the second panel 12.Thus, make chuck 40 when the crimp 321 of workpiece 320 will be crossed when driving chuck 40 with handle 70, pull with hand lifting hand lever 270 to rise, then the effect by the first support arm 280 and the second support arm 290 understood by lifting hand lever 270, lifting ring 290 is made to increase, and then lifting ring 290 promotion lifting axle sleeve 50 rises, lifting axle sleeve 50 can, by the effect of above-mentioned Connection Block 60, make chuck 40 rise and can cross the crimp 321 of workpiece 320; And cross the crimp 321 of workpiece 320 at chuck 40 after, pull with hand lifting hand lever 270 to decline, then lifting ring 390 declines, lifting axle sleeve 50 can decline under self gravitation effect, make chuck 40 be stuck on the crimp 321 of workpiece 320, now, handle 70 is pulled out, chuck 40 can be made to be separated with the outer hook of scroll spring 360, and the outer hook of scroll spring 360 is hooked on described crimp 321.This manual hoisting device and pull unit cooperatively interact, and the outer hook of scroll spring 360 is successfully snapped on the crimp 321 of workpiece 320.
11, described location-plate 350 plays the role of positioning in scroll spring 360 installation process, prevents workpiece 320 from rotating.
12, described movable shifting block 330 can the edge of workpiece pressing 320, turns over side when preventing scroll spring 360 from installing.
The above embodiment only have expressed the specific embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
