When the invention is used, the shell 1 does not need to be frequently moved, can be welded on a fixed frame or embedded on a construction site, and can also be fixed by other existing fixing modes such as bolts and the like, because the shell does not need to be frequently moved, the shell can be directly fixed, taking the motor shown in figure 6 as an example, when the invention is used, the main adjusting plate 2 is moved to enable the position of the main adjusting plate to be matched with the length direction (the up-down direction in figure 1) of the position of a through hole A on a motor base, then the pull rod 3-2 is moved to enable the pull rod 3-2 to be matched with the width direction of the position of the hole A, then the motor is dropped, the pull rod 3-2 is enabled to penetrate through the through hole A from the lower part, because the pull rod 3-2 can be adjusted to the upright state, if the position has slight deviation, under the condition that the motor is not particularly large, the position can be adjusted by fingers while the motor is moved to carry out fine adjustment, if the equipment is large, one person carries the motor to fall, the other person holds the pull rod 3-2 by hand to align the pull rod with the through hole A, if the equipment is a large motor or other equipment, a hoisting mode is generally adopted, so that when the equipment is hoisted to fall, a constructor only holds the motor by one hand and adjusts and aligns the pull rod with the through hole A by the other hand, in a word, the operation can be easily realized, after the pull rod 3-2 passes through the through hole, the part passing through the through hole is generally processed in two modes, one mode is to insert the L-shaped inserting rod 3-2-1 into the transverse through hole at the top of the pull rod 3-2, the L-shaped inserting rod 3-2-1 is an L-shaped structure formed by a vertical rod and a transverse rod (as shown in figure 2, the vertical rod is prevented from falling out of the transverse through hole, the length of the transverse rod is larger than the diameter of the through hole A and is used for being clamped at the through hole A, the other mode is to provide external threads at the top end of the pull rod 3-2, then a nut C is screwed on the external thread, the height of the nuts on the four pull rods 3-2 should be approximately equal (in order to ensure that the height of the four nuts can be ensured, a clamping key is welded on the pull rod 3-2, the nut is stopped when rotating to the position, the clamping key is too large, if the clamping key is too large, the pull rod 3-2 is prevented from passing through the through hole A, of course, the bottom of the nut C is also provided with a transverse through hole and an L-shaped inserting rod 3-2-1, after the pull rod 3-2 passes through the through hole A, the L-shaped inserting rod 3-2-1 is inserted, the L-shaped inserting rod 3-2-1 plays a role of limiting the nut C, and the diameter of the four nuts is larger than that of the through hole A so as to be used for clamping at the through hole A.

After the steps are completed, the adjusting rotary disc 5 is rotated to drive the adjusting rotary tube 3-3 to rotate, so that the external threaded rod 3-1-2 moves upwards and drives the rear end of the movable wane 3-1 to move upwards, the front end of the movable wane 3-1 moves downwards and pulls the four pull rods 3-2 to move downwards until the L-shaped inserted rod 3-2-1 or the nut blocks the through hole A to complete temporary locking and positioning, because the external threaded rod 3-1-2 and the adjusting rotary tube 3-3 are in threaded fit, even if the adjusting rotary tube 3-3 is slightly loosened by vibration in the using process, the external threaded rod 3-1-2 cannot be lowered too much, and certainly, in order to better reduce the possibility of autorotation of the adjusting rotary tube 3-3, the damping mode of the adjusting rotary tube 3-3 can be increased, this is prior art and the ratchet tooth-sharp mode of the present application can be used, because the adjusting dial 5 can only rotate in one direction due to the ratchet action of the ratchet wheel, thus, the adjusting rotary tube 3-3 can be further limited to reverse rotation.

When the motor needs to be replaced or disassembled, as shown in figure 1, one hand pulls the movable sliding block 3-3-3 rightwards to enable the ratchet 3-3-2 to be separated from the ratchet wheel, at the moment, the return spring 3-3-5 is compressed, then, the other hand reverses the adjusting rotary disc 5 to enable the external thread rod 3-1-2 to move downwards, further, the four pull rods 3-2 move upwards, then the L-shaped inserting rods 3-2-1 or nuts on the four pull rods are taken off, the motor is lifted, and in addition, when the sliding block 3-3-3 is loosened, the ratchet wheel is engaged again under the action of the return spring 3-3-5.

When a motor of another type or another size needs to be fixed, the main adjusting plate 2 and the four pull rods 3-2 are continuously moved to be suitable for new position requirements, and then the actions are repeated. The grinding wheel is applied to a vertical grinder for the same reason.

The invention can be suitable for various small and medium-sized equipment with the base provided with the fixing through hole A, such as a vertical grinder and the like, does not need to frequently reset positioning points, is very convenient and efficient to use, and is more suitable for places with more equipment, various equipment models or frequent equipment updating.
