During operation, the connecting rod is driven by the deflector rod to move back and forth, then the trapezoidal push block is pushed to move back and forth, the trapezoidal push block moves forward, the right nail pushing groove and the left nail pushing groove are gradually pushed away, and the foldable state and the unfolded state are achieved. The shifting lever 8 is provided with a positioning mechanism for fixing the shifting lever, and when the shifting lever is positioned at two limit positions, the shifting lever is fixed to prevent unnecessary sliding of the right nail abutting groove in the working process. The side wall of the trapezoid push block 4 is provided with a jacking groove 5 which is an oblique groove, and the right nail supporting groove is driven to move through a sliding rod in the jacking groove under the action of the trapezoid push block, so that the right nail supporting groove moves from the lower part of the left nail supporting groove to be flush with the left nail supporting groove. The jacking groove realizes the left-right movement of the right nail supporting groove and the up-down movement of the right nail supporting groove, so that the right nail supporting groove can be folded and unfolded relative to the left nail supporting groove, and the nail pushing device is simple in structure and convenient to operate.

Furthermore, as shown in fig. 2, the middle part of the shift lever 8 is hinged to the handle portion 1, the lower part of the shift lever 8 is hinged to the connecting rod 7, the upper part of the shift lever 8 is provided with a push rod 9, two ends of the push rod 9 respectively extend out of the handle portion 1, namely, the shift lever can be shifted from two sides of the handle portion, when in use, the push rod is pushed to drive the shift lever to swing so as to drive the connecting rod to move back and forth, the positioning mechanism comprises a movable pin shaft 10 arranged on the shift lever 8 and two limit hole grooves 11 arranged on the handle portion 1, and the movable pin shaft 10 is movably arranged in a. The two limit hole grooves 11 are respectively positioned at two ends of the circular arc-shaped trajectory line of the movable pin shaft 10, and the movable pin shaft 10 corresponds to the limit hole grooves 11. In the process of forward and backward swinging of the deflector rod, the movable pin shaft moves in a circular arc track, when the deflector rod pushes the trapezoidal push block to the foremost end, the right nail pushing groove is located at the folded limit position, when the deflector rod pushes the trapezoidal push block to the rearmost end, the right nail pushing groove is located at the unfolded limit position, at the two limit positions, the central axis of the movable pin shaft is overlapped with the central axis of the limit hole groove, the movable pin shaft is inserted into the limit hole groove, fixing of the deflector rod is achieved, and the right nail pushing groove is stably kept at the folded limit position or the unfolded limit position.

Embodiment 2, as shown in fig. 10, the positioning mechanism includes a clamping strip 20 disposed on the shift lever 8 and two limit clamping seats 21 disposed on the handle portion 1, the two limit clamping seats 21 are respectively located at two ends of the circular arc-shaped trajectory line of the clamping strip 20, and the clamping strip 20 corresponds to the limit clamping seats 21. When the shifting lever swings to the two limit positions, the clamping strip on the shifting lever is just clamped into the limit clamping seat to fix the shifting lever and prevent the shifting lever from sliding.

Further, as shown in fig. 4 to 6, the cross section of the left nail abutting groove 32 is a flat plate shape; the cross section of the right nail pushing groove 33 is flat, the rear part of the flat is provided with a tail seat, the slide bar is arranged below the rear part of the right nail pushing groove, and the width of the left nail pushing groove can be the same as that of the right nail pushing groove. The jacking groove 5 is an inclined groove in a horizontal plane and an arc-shaped groove upwards in a vertical plane, and when the slide bar 6 is positioned at the tail end of the jacking groove 5, the right nail pushing groove 33 is folded below the left nail pushing groove 32; when the slide bar 6 is positioned at the uppermost part of the jacking groove 5, the right nail pushing groove 33 and the left nail pushing groove 32 are positioned at the same horizontal height, and the right nail pushing groove is in an unfolded state. The communicating pipe 2 is internally provided with limit blocks 12, the lower part of the right nail abutting groove 33 is provided with a stop block 13, the stop block 13 is positioned between the limit blocks 12, and the slide rod 6 is fixedly arranged on the stop block 13. Under the action of the limiting block, the right nail pushing groove can only move left and right and up and down, and does not move back and forth, so that the original position of the right nail pushing groove can move upwards in an arc or downwards in an arc. When the trapezoidal push block moves forwards through the connecting rod, the right nail pushing groove is enabled to translate rightwards through the change of the width of the jacking groove, when the sliding rod reaches the upper portion of the jacking groove, the right nail pushing groove moves upwards through the upward arc-shaped sliding groove, so that the folding state is changed into the unfolding state, and the folding is convenient, simple and feasible.
