The connecting rod 17 can slide in the boss 101. The through hole can realize the movement of the connecting rod 17 in the boss 101. Thus, the second fastening seat 15 and the first fastening seat 16 can drive the movable seat 2 to move along the length direction of the tightening groove 701.

[0050] An adjusting unit is installed between the movable seat 2 and the mounting seat 1. When the input shaft is located in the tightening groove 701, the adjusting unit can fix the position of the movable seat 2. When the adjusting unit releases the movable seat 2, the movable seat 2 can be slid along the avoiding groove 7 for disassembly.

[0051] The adjusting unit includes a pull rod 10, a limiting block 9 and a semicircular block 14.

[0052] The side wall of the mounting base 1 is provided with a clearance hole, one end of the pull rod 10 is rotatably installed on the second fastening base 15, and the other end of the pull rod 10 penetrates the clearance hole and is located outside the mounting base 1.

[0053] The limiting block 9 is fixedly installed on the pull rod 10, and two limiting blocks 9 are arranged along the circumferential direction of the pull rod 10.

[0054] The mounting base 1 is fixedly provided with a sleeve 11 coaxial with the clearance hole. Two semicircular blocks 14 are arranged along the sleeve 11. The semicircular blocks 14 are fixedly installed on the inner wall of the sleeve 11. The two semicircular blocks 14 are spaced apart to form a straight sliding groove 1401, and the size of the limiting block 9 is smaller than the size of the straight sliding groove 1401. The limiting block 9 can slide along the straight sliding groove 1401.

[0055] The semicircular block 14 is provided with an inclined surface 1402 and a flat surface 1403 away from the mounting base 1. The thickness of the inclined surface 1402 close to the flat surface 1403 is greater than the thickness of the inclined surface 1402 away from the flat surface 1403.

[0056] The first fastening base 16 between the mounting base 1 and the vertical plate of the movable base 2 is provided with an elastic block 18.

[0057] The specific use method is as follows:

[0058] Start the motor 3, and the rotation of the motor 3 can drive the reduction gear 8 to rotate, and then drive the second pulley 6 to rotate through the belt 5 to drive the first pulley 4 to rotate, so that the inner cylinder 13 completes the oil injection operation.

[0059] When the motor 3 and the reduction gear 8 need to be installed, the initial belt 5 is in a relaxed state, and the movable base 2 is located outside the mounting base 1.

[0060] First, the movable base 2 with the motor 3 and the reduction gear 8 is installed on the first fastening base 16 and the second fastening base 15. Specifically, the vertical plate of the movable base 2 is aligned with the installation groove of the second fastening base 15 and the first fastening base 16, respectively, and the vertical plate of the movable base 2 is placed in the installation groove of the second fastening base 15 and the first fastening base 16. At this time, the movable base 2 is pushed towards the taut groove 701, and the movable base 2 slides along the installation groove. At the same time, the input shaft of the reduction gear 8 slides along the avoiding groove 7 towards the taut groove 701.

[0061] When the movable seat 2 is pushed into the mounting seat 1, the pull rod 10 is pulled away from the tightening groove 701 when the second pulley 6 is opposite to the tightening groove 701. The pull rod 10 is moved away from the mounting seat 1, and the pull rod 10 drives the limiting block 9 to move together along the straight sliding groove 1401. When the limiting block 9 is pulled out of the straight sliding groove 1401, the limiting block 9 on the pull rod 10 reaches the position tangent to the lowest point of the inclined surface 1402 of the semicircular block 14, and at this time, the vertical plate of the movable seat 2 is on the elastic block 18. The pull rod 10 is turned, and the limiting block 9 slides on the inclined surface 1402. Because there is a thickness difference between the inclined surface 1402 and the plane 1403, when the pull rod 10 is turned and the limiting block 9 gradually reaches the plane 1403, the vertical plate of the movable seat 2 close to the first fastening seat 16 can extrude the elastic block 18 to deform the elastic block 18. When the limiting block 9 is turned to the plane 1403, the pull rod 10 is limited. At this time, the movable seat 2 is fixed, and the input shaft is moved to the end of the tightening groove 701. The belt 5 is tightened. The motor can be started to perform oil injection work.

[0062] When disassembly is needed, the pull rod 10 is turned in the opposite direction to make the limiting block 9 turn from the plane 1403 to the lowest point of the inclined surface 1402, at this time, the elastic block 18 restores the deformation, and the belt 5 between the first pulley 4 and the second pulley 6 is not tightened, which facilitates the disassembly of the belt 5. When the limiting block 9 is turned to correspond to the straight sliding groove 1401 again, the pull rod 10 is pushed in the direction close to the mounting seat 1, and the pull rod 10 pushes the movable seat 2 and the speed reducer 8 to move in the direction close to the avoiding groove 7. The input shaft of the speed reducer 8 slides from the tightening groove 701 to the avoiding groove 7. The movable seat 2 is pulled out as a whole, which facilitates the maintenance of the speed reducer 8 or the motor 3, and further improves the convenience and practicality of the device during use.

[0063] It should be noted that when the movable seat 2 is installed, other lifting devices need to be assisted, and when the movable seat 2 is moved, the pull rod 10 can be driven by a cylinder or the like, or balls are arranged on the contact surfaces between the second fastening seat 15 and the first fastening seat 16 and the inner wall of the mounting seat 1 and in the mounting groove of the second fastening seat 15 and the first fastening seat 16, and the contact area can be reduced through the contact of the balls, and a very small force can be used to pull.

[0064] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
