As shown in fig. 1 and 2, the novel adjustable socket wrench with an inner hexagon comprises a wrench bracket 1, a wrench base 3, a hexagon-shaped plate 5, an intermediate gear shaft 7 and a rotary hand wheel 11.

The wrench holder 1 includes a sleeve portion 1-1 and a handle portion 1-2 provided on one side of the sleeve portion 1-1, and the sleeve portion 1-1 and the handle portion 1-2 are integrally formed. The lower end of the sleeve part 1-1 is open, the upper end is provided with a shaft hole 1-3, and a rolling bearing 8 is arranged in the shaft hole 1-3. The upper side of the shaft hole 1-3 is provided with a bearing press ring 9, the bearing press ring 9 is fixed at the upper end of the sleeve part 1-1 through a slotted countersunk head screw II 10, the lower end of the shaft hole 1-3 is provided with an inner shoulder 1-4, and the outer ring of the rolling bearing 8 is fixed with the inner shoulder 1-4 through the bearing press ring 9.

6 hexagonal forming plates 5 are distributed in the sleeve part 1-1 along the circumferential direction, the inner side surfaces of the hexagonal forming plates 5 form a regular hexagonal opening 15, each hexagonal forming plate 5 is provided with a waist-shaped position hole 14, the included angle between every two adjacent waist-shaped position holes 14 is 60 degrees, the upper part of each hexagonal forming plate 5 is provided with a rack block 6, the rack block 6 is fixedly welded with the hexagonal forming plate 5, the rack block 6 and the waist-shaped position holes 14 on each hexagonal forming plate 5 are arranged in parallel, the rack block 6 is meshed with the lower part of the intermediate gear shaft 7 to form a gear-rack connecting pair, the lower part of the intermediate gear shaft 7 is provided with an outer shoulder 7-1, and the outer shoulder 7-1 is positioned on the upper side of the rack block 6 to prevent the intermediate gear shaft 7 from sliding downwards. The upper portion of the intermediate gear shaft 7 penetrates through an inner ring of the rolling bearing 8 and is provided with a rotary hand wheel 11, the rotary hand wheel 11 is connected with the intermediate gear shaft 7 through a thread pair, a hand wheel pressing ring 12 is arranged above the rotary hand wheel 11, the hand wheel pressing ring 12 is fixed at the upper end of the intermediate gear shaft 7 through a slotted countersunk head screw I13, the rotary hand wheel 11 is pressed and fixed through the hand wheel pressing ring 12, and the rotary hand wheel 11 is prevented from loosening.

The wrench base 3 is arranged at the bottom of the hexagonal formed plate 5 and fixed with the sleeve part 1-1 through the inner hexagonal screw 2 and is used for supporting the hexagonal formed plate 5 and the middle gear shaft 7. Waist-shaped driving pins 4 which are in one-to-one correspondence with the hexagonal forming plates 5 are arranged at the top of the wrench base 3, the waist-shaped driving pins 4 are welded and fixed with the wrench base 3, and the waist-shaped driving pins 4 are inserted into the waist-shaped position holes 14 and can slide along the waist-shaped position holes 14.
