the inner parts of the two groups of connecting blocks 212 are movably connected with first threaded rods 216 through bearings, the ends, close to each other, of the two groups of first threaded rods 216 are movably connected with clamping blocks 217 through bearings, the two sides of the ends, far away from each other, of the two groups of clamping blocks 217 are fixedly connected with limiting rods 218, the other ends of the two groups of limiting rods 218 extend into the connecting blocks 212, notches matched with the limiting rods 218 are formed in the connecting blocks 212, and the clamping blocks 217 can move through the rotation of the first threaded rods 216 due to the design, so that the shell can be clamped;

the middle of the top end of the mounting base plate 111 is provided with a height adjusting mechanism 3.

Furthermore, two outer sides of the two sets of worms 215 are movably connected to the fixing plate 214 through bearings, and one ends of the fixing plates 214, which are close to the mounting connecting plate 112, on the two sides are fixedly connected to the fixing plate 214, so that the worms 215 are limited by the fixing plate 214.

Furthermore, the two sets of worm screws 215 are fixedly connected with belt pulleys 219 at the rear sides of the outer portions thereof, and the two sets of belt pulleys 219 are movably connected with each other through a transmission belt 220, so that the worm screws 215 at the two sides can synchronously rotate due to the design.

Furthermore, the rotating block 221 is fixedly connected to one end, away from each other, of each of the two first threaded rods 216 and the end portion of the worm 215, and anti-slip threads are arranged on the outer portion of the rotating block 221, so that the worm 215 and the first threaded rods 216 can be rotated more conveniently.

Further, height adjusting mechanism 3 includes screw thread loop bar 311, there is screw thread loop bar 311 at 111 top middle parts of mounting plate through bearing swing joint, and screw thread loop bar 311 is inside to have second threaded rod 312 through threaded connection, bearing swing joint is on placing bottom plate 114 bottom middle part on the second threaded rod 312 top, and all fixedly connected with auxiliary loop bar 313 on the both sides on mounting plate 111 top, auxiliary loop bar 313 is inside all to be inserted and is equipped with auxiliary inserted bar 314, and the top fixedly connected with of auxiliary inserted bar 314 places on the both sides of bottom plate 114 bottom, adopt this kind of design to be convenient for make second threaded rod 312 remove through the rotation of screw thread loop bar 311, simultaneously through the guide of auxiliary inserted bar 314, make and place bottom plate 114 and can carry out stable reciprocating.

Further, the outer upper side of the threaded sleeve rod 311 is fixedly connected with a fixing ring 315, and the outer portion of the fixing ring 315 is fixedly connected with a rotating rod 316.

The working principle is as follows: when people need drill the speed reducer shell, can place the speed reducer shell on placing bottom plate 114, rotate the gag lever post 218 of both sides respectively afterwards, when rotating first threaded rod 216, because first threaded rod 216 and even piece 212 threaded connection, thereby make first threaded rod 216 to being close to even board 112 inside and remove of installation, can drive clamp splice 217 when first threaded rod 216 removes, and clamp splice 217 is spacing by gag lever post 218, thereby make clamp splice 217 unable the rotation, when the clamp splice 217 of both sides tightly butts with the both sides of casing respectively, can accomplish fixedly.

The worm 215 on any side can be rotated, when the worm 215 on one side is rotated, the worm 215 on the other side is driven to rotate through the belt pulley 219 and the transmission belt 220, when the worms 215 on two sides are rotated, the worm wheel 213 is driven to rotate, when the worm wheel 213 rotates, the movable clamping block 211, the first threaded rod 216 and the limiting rod 218 are driven to integrally rotate, so that the whole shell can rotate, and due to the fact that the worm 215 and the first threaded rod 216 have self-locking performance, locking can be completed only by stopping rotation of the worm 215 after adjustment is completed.

When people are using to place bottom plate 114, go back accessible and rotate screw sleeve pole 311, because second threaded rod 312 and screw sleeve pole 311 threaded connection when rotating screw sleeve pole 311 to make second threaded rod 312 upward movement, when second threaded rod 312 rebound, can drive and place bottom plate 114 rebound, when needs place bottom plate 114 rebound, only need the reverse rotation screw sleeve pole 311 can, thereby adjust the height that the casing was originally placed.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
