As shown in fig. 1-8, the present invention comprises a barrel 1, a rotating member 2 disposed at the rear of the barrel 1, a frame assembly 4 for mounting the rotating member 2, a movable handle 3 mounted below the frame assembly, and a battery pack 5 for power supply, wherein the frame assembly 4 comprises a firing member 47, a frame bracket 411, a stroke adjusting device 43 mounted above the frame bracket 411, a circuit board 42 mounted on the stroke adjusting device 43, a manual reset wrench 41 disposed at the top of the frame bracket 411, a rack assembly 44 mounted at the rear of the frame bracket 411, a jaw opening button 45 disposed at the side of the frame bracket 411, a movable handle locking member 46 for limiting the movable handle 3, a transmission gear engaged with the rack assembly 44, and a driving motor 49 for driving the transmission gear 48, the stroke adjusting device comprises a stroke adjusting block 436, a stroke adjusting block handle 431 arranged on the stroke adjusting block 436, a positioning reed 432 for positioning the position of the stroke adjusting block 436, a contact switch trigger, a lower cover 438 for arranging the contact switch trigger, a manual knife return button 437 arranged on the lower cover 438 and an upper cover 439 matched with the lower cover 438.

An elongated slot is formed in the middle of the stroke adjusting block 436, a protrusion 4361 is arranged in the elongated slot, a groove matched with the positioning spring piece 432 is formed in the surface of the stroke adjusting block 436, and an L-shaped moving channel 4381 for accommodating the contact switch trigger is arranged on the lower cover 438. The manual knife retracting button 437 is provided with three fingers 4371 with the same structure, two sides of each finger 4371 are provided with a limit block 4372, and the lower cover 438 is provided with a limit groove 4382 for accommodating the limit block 4372. The manual reset gear 4101 is fixed by a positioning pin, the lower cover 438 is provided with positioning pin through holes 4383 for accommodating the positioning pins, and the number of the contact switch triggers is three.

The rack assembly 44 includes a closing driver 441, a rack 442 installed on the closing driver 441, a rack stopper pin 444 disposed at an end of the rack 442, and a rack stopper pin pressure spring 443 for fixing the rack stopper pin 444, wherein the rack 442 is provided with an inclined surface 4421 and a rack stopper pin driving surface 4422, and the closing driver 441 is provided with a abdicating notch 4411. The rack 442 is provided with contact switch reset pins, the number of the contact switch reset pins is three, the rack is provided with contact switch trigger pins 4426, the rack 442 and the contact switch reset pins are in interference fit, the heights of the three contact switch reset pins are sequentially increased and respectively include a first contact switch reset pin 4423, a second contact switch reset pin 4424 and a third contact switch reset pin 4425, and the heights of the contact switch trigger pins 4426 are consistent with the height of the highest third contact switch reset pin 4425.

The sewing stroke of the electric anastomat is 30mm, 45mm and 60mm, when the electric anastomat is in an initial state, the pin of the contact switch trigger 4431 is contacted with the contact switch reset pin 4423 on the rack 442, when the electric anastomat is in a closed state, the movable handle 3 is closed, the movable handle limiting block 46 limits the reset of the movable handle 31, and when the electric anastomat is triggered to reach the stroke of 30mm, the contact switch trigger pin 4426 is contacted with the pin of the first contact switch trigger 433. Correspondingly, the stroke adjusting device has the switching under 3 stroke states, when the handle 431 of the stroke adjusting block is stirred to move left, the third contact switch trigger 435 moves upwards under the action of a special structure groove in the stroke adjusting block 436, the second contact switch trigger 434 moves downwards under the action of a protrusion 4361 in the groove of the stroke adjusting block 436, and when the positioning spring piece 432 of the stroke adjusting block just falls into a groove on the surface of the stroke adjusting block 436, a sound prompt is sent out to indicate that the stroke adjustment is finished, namely the sewing stroke of the electric endoscope anastomat is adjusted to 45mm from 60 mm; the process that the sewing stroke of the electric endoscope anastomat is adjusted from 45mm to 30mm is the same as the process. When the stroke of the electric endoscope anastomat is adjusted to 45mm or 60mm from 30mm, only the stroke adjusting block handle 431 needs to be moved rightwards. After the stroke adjustment is completed, the first contact switch trigger 433, the second contact switch trigger 434, and the third contact switch trigger 435 cannot move up and down due to the limitation of the long groove inside the stroke adjustment block 436.
