[0024] The one side of fixed disc 14 is welded with positioning pin 15, and positioning pin 15 is connected with the fixed disc 14 on the right side of fixed disc 14, to facilitate the connection of the fixed disc 14 of five level turntable 5, four level turntable 6, three level turntable 7, two level turntable 8, and the one side of fixed seat 4 is connected with two installation clamping pins 16, and installation clamping pins 16 are connected with fixed disc 14, to facilitate the installation of five level turntable 5, four level turntable 6, three level turntable 7, two level turntable 8, one level turntable 9, and the top of hydraulic wrench body 1 is connected with cover plate 23, to prevent dust from falling into installation groove 3, to avoid affecting the rotation of five level turntable 5, four level turntable 6, three level turntable 7, two level turntable 8, one level turntable 9, to ensure the normal counting of hydraulic wrench body 1.

[0025] The working principle of the embodiment is as follows: in use, firstly, the hydraulic wrench body 1 is twisted once under the stretching of the hydraulic rod 2, at the same time, the driving rod 20 is driven to rotate under the stretching of the hydraulic rod 2, so as to drive the rotating shaft 19 to rotate, at this time, the number of the primary dial 9 is driven from 0 to 1 under the restriction of the ratchet 18 and the ratchet groove 17, so as to count once, then, the hydraulic wrench body 1 is reset under the contraction of the hydraulic cylinder 2, at the same time, the driving rod 20 and the rotating shaft 19 are driven to rotate back under the attraction of the magnet rod 21 and the hydraulic rod 2, at this time, the ratchet 18 can slide along the ratchet groove 17 without restriction, so as to reset the ratchet 18, then, the hydraulic cylinder 2 is stretched again, and the counting is performed according to the above steps, until the number of the primary dial 9 is rotated to 9, so as to complete the counting of one digit;

[0026] At this time, the driving gear of the double-layer gear 13 on the secondary dial 8 is engaged with the driving clamping slot 22 of the primary dial 9, therefore, the driving gear of the secondary dial 8 is driven to rotate by the rotation of the primary dial 9, so as to drive the driven gear of the secondary dial 8 to rotate, then, the number of the secondary dial 8 is driven from 0 to 1 under the meshing of the driven gear and the annular tooth groove 10, so as to realize the carry-over of one digit to two digits, then, the primary dial 9 is continuously driven to rotate by the hydraulic rod 2, at this time, the driving gear of the secondary dial 8 is disengaged from the driving clamping slot 22 of the primary dial 9, therefore, the secondary dial 8 will not be driven to rotate by the primary dial 9, until the number on the primary dial 9 is rotated to 9, at this time, the driving gear of the secondary dial 8 is engaged with the driving clamping slot 22 of the primary dial 9 again, therefore, the driving gear of the secondary dial 8 is driven to rotate by the primary dial 9, so as to drive the driven gear of the secondary dial 8 to rotate, then, the number of the secondary dial 8 is driven from 1 to 2 under the meshing of the driven gear and the annular tooth groove 10, the counting is performed according to the above steps, until the number of the secondary dial 8 is rotated to 9, so as to complete the counting of two digits;

[0027] At this time, the driving gear of the third dial 7 will be engaged with the push card slot 22 of the second dial 8, so that the second dial 8 drives the driving gear of the third dial 7 to rotate, and then drives the driven gear to rotate, and then drives the third dial 7 to rotate under the meshing action of the driven gear of the third dial 7 and the annular tooth groove 10, so as to turn the number of the third dial 7 from 0 to 1, and then realize the carry of two digits to three digits. Then, the first dial 9 continues to rotate, at this time, the driving gear of the third dial 7 is disengaged from the push card slot 22 of the second dial 8, and the driving gear of the second dial 8 is disengaged from the push card slot 22 of the first dial 9, so that the second dial 8 and the third dial 7 will not be driven to rotate, until the first dial 9 rotates to 9, at this time, the driving gear of the second dial 8 is engaged with the push card slot 22 of the first dial 9 again, so as to drive the second dial 8 to rotate, and then turn the number of the second dial 8 from 0 to 1, until the number of the second dial 8 is turned to 9, at this time, the driving gear of the third dial 7 is engaged with the push card slot 22 of the second dial 8 again, so as to turn the number of the third dial 7 from 1 to 2, and then count according to the above steps, until the number of the third dial 7 is turned to 9, so as to complete the counting of three digits.

[0028] Then, according to the above steps, the counting of four digits, five digits and subsequent digits is completed.

[0029] The above is only the preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
