[0037] In this embodiment, when the shell of the instrument is needed to be installed, the outer shell is placed on the fixing plate 7, the clamping blocks 33 are clamped on the outer wall of the shell by a plurality of air cylinders 32, then the shell cover is placed on the top surface of the outer shell, the motor 4 is started to drive the connecting sleeves 8 to be clamped in the clamping grooves 11 provided outside the connecting rod 9 through the plurality of clamping blocks 10 in the connecting sleeves 8, so that the connecting rod 9 drives the screw rod 3 to rotate, the screw rod 3 is threadedly connected with the transmission frame 5, so that the transmission frame 5 drives the pressing plate 6 to press down the shell cover and the outer shell to be buckled, when the buckling is completed, the resistance of the downward pressing is greater than the preset pushing force of the set pressure spring 17, the screw rod 3 stops rotating, the connecting rod 9 driven by the screw rod 3 does not rotate, then the arc-shaped design of the plurality of clamping grooves 11 enables the clamping blocks 10 to be separated from the clamping grooves 11, the plurality of clamping blocks 10 are separated from the abutment of the push block 16, so that the push block 16 drives the installation ring 15 and the plurality of movable rods 14 to drive the sliding plate 13 to stretch the set pressure spring 17, at this time, the connecting rod 9 and the connecting sleeve 8 form an idle rotation, the power transmission of the motor 4 and the screw rod 3 is cut off, then the motor 4 is turned off, the push block 16 is driven by the plurality of set pressure springs 17 to clamp the clamping blocks 10 in the clamping grooves 11, and the power transmission of the motor 4 and the screw rod 3 is restored.

[0038] More specifically, when the preset force of the preset spring 17 needs to be adjusted, rotate the rotating sleeve 26 to drive the limiting ring 27 to rotate, and at the same time, extrude the compression spring through the multiple sets of pressing blocks 36. The limiting ring 27 drives the multiple sets of displacement grooves 30 to move to the inside of the limiting plate 29, thereby removing the abutment of the limiting plate 29 to the limiting ring 27. Then, the sliding abutment sleeve 25 removes the abutment to the limiting sleeve 24, and then the sliding limiting sleeve 24 removes the abutment to the multiple sets of limiting blocks 21. Through the multiple sets of return springs 22, pull the limiting blocks 21 out of the limiting grooves 23, and then slide the sleeve 20 to drive the multiple sets of adjusting blocks 18 to stretch the preset spring 17 to increase the preset force of the preset spring 17. Then, through the limiting sleeve 24, push the multiple sets of limiting blocks 21 to make them engage in the limiting grooves 23, and abut the abutment sleeve 25 against the top surface of the limiting sleeve 24. At this time, the limiting blocks 21 move in the displacement grooves 30, and the rotating sleeve 26 drives the limiting ring 27 to rotate so that the limiting plate 29 abuts against the outer wall of the limiting ring 27 to abut and limit the limiting sleeve 24.

[0039] In summary, when the shell of the instrument needs to be installed, place the outer shell on the placement plate 7, and then push the clamping block 33 to abut against the outer wall of the shell through the multiple sets of cylinders 32. Then, place the shell cover on the top surface of the outer shell, and start the motor 4 to make the multiple sets of clamping blocks 10 in the connecting sleeve 8 engage in the clamping grooves 11 outside the connecting rod 9, so as to drive the connecting rod 9 to rotate the screw rod 3. The screw rod 3 rotates and threadedly cooperates with the transmission frame 5, thereby driving the transmission frame 5 to push the pressing plate 6 to press down the shell cover and the outer shell to be buckled. When the buckling is completed, the resistance of the downward pressure is greater than the preset pushing force of the preset spring 17, the screw rod 3 stops rotating, the connecting rod 9 driven by the screw rod 3 will not rotate, and the arc-shaped design of the multiple sets of clamping grooves 11 will make the clamping blocks 10 disengage in the clamping grooves 11. The disengagement of the multiple sets of clamping blocks 10 from the abutment of the pushing block 16 makes the pushing block 16 push the installation ring 15 and the multiple sets of movable rods 14 to drive the sliding plate 13 to stretch the preset spring 17. At this time, the connecting rod 9 and the connecting sleeve 8 form an idle rotation, thereby cutting off the power transmission of the motor 4 and the screw rod 3. Then, close the motor 4, drive the pushing block 16 to push the clamping blocks 10 to engage in the clamping grooves 11 through the multiple sets of preset springs 17, and restore the power transmission of the motor 4 and the screw rod 3.

[0040] When the preset force of the pressure spring 17 needs to be adjusted, the rotating sleeve 26 drives the limiting ring 27 to rotate, and at the same time, the pressure spring is extruded through a plurality of groups of pressing blocks 36; the limiting ring 27 drives a plurality of groups of displacement slots 30 to move to the inner side of the limiting plate 29, thereby removing the abutment of the limiting plate 29 on the limiting ring 27; then the sliding abutment sleeve 25 removes the abutment on the limiting sleeve 24; then the sliding limiting sleeve 24 removes the abutment on a plurality of groups of limiting blocks 21; the limiting block 21 is pulled out of the limiting slot 23 through a plurality of groups of return springs 22; then the sliding sleeve 20 drives a plurality of groups of adjusting blocks 18 to stretch the pressure spring 17 to increase the preset force of the pressure spring 17; then the limiting sleeve 24 pushes a plurality of groups of limiting blocks 21 to make them clamped in the limiting slot 23; the abutment sleeve 25 is abutted on the top surface of the limiting sleeve 24; at this time, the limiting block 21 moves in the displacement slot 30; the rotating sleeve 26 drives the limiting ring 27 to rotate, so that the limiting plate 29 is abutted on the outer wall of the limiting ring 27 to abut and limit the limiting sleeve 24.
