After the air passage 64 is guided into the propulsion chamber 612, the propulsion disc 73 is pushed along the axis X toward the carriage unit 3, thereby driving the push plate 72 toward the front barrier wall 31 via the push rod 71. The direction is moved to press the object 2 to be extruded.

When the reversing member 55 is in the retracted position, the high-pressure air sent through the intake nozzle 52 passes through the corresponding venting opening 66 of the retreating chamber 611, sequentially passes through the corresponding venting groove 68 and flows into the phase. After the corresponding air passage 64 is guided, it is guided into the retreating chamber 611, and pushes the propulsion disc 73 along the axis X to move in the opposite direction to the bracket unit 3, thereby driving the pushing disc 72 toward the push rod 72 via the push rod 71. Conversely, in the direction of the front retaining wall 31, the user can temporarily remove the bayonet 342 to the latch 341 and replace the new object to be squeezed 2 to continue the cleaning operation.

Referring to FIG. 10 and FIG. 11, as the smearing operation gradually proceeds to a lower position, The user can choose to change the grip member 51 from the lower grip position to the lift position. First, the grip slider 59 is detached from the housing 57, and then the reversing member 55 is communicated with the flow direction. The air pipe joint 8 of the valve 56 is detached from the reversing member 55, and the casing 57 can be temporarily detached from the reversing member 55, and the casing 57 is pushed to move along the axis X in the direction of the rifle 6. The housing 57 is rotated by the lower side of the barrel 6 to the upper side of the barrel 6 by the connecting ring 58 rotating about the axis X by 180 degrees. At the same time, the outer cover 67 to which the reversing member 55 is to be mounted is mounted. Rotating about 180 degrees about the axis X and rotating from below the barrel 6 to above the barrel 6, and then moving the housing 57 along the axis X toward the direction of the bracket unit 3, and reversing The member 55 is mounted back to the housing 57 to mount the air pipe connector 8 back to the reversing member 55, and finally the handle slider 59 is mounted back to the housing 57. At this time, the grip member 51 is held by the lower grip. The position is changed to the raised position, and the user can press the lift switch 54 while switching with the reverse member 55 between the advanced position and the retracted position for playing Operations.

In summary, the grip member 51 can be quickly changed between the lower grip position and the lifted position relative to the grip 6 without disassembling the bracket unit 3 or adding additional parts. It can meet the needs of different levels of smear work, and has the effect of increasing the convenience of use, so it can achieve the object of the present invention.

It is worth mentioning that, since the latch 342 of the limit group 34 can fix the light weight of the object to be squeezed 2 in the pushing space 35, when the object to be squeezed 2 is performed along with the smashing operation When the weight is gradually reduced, the user can directly change the position of the grip member 51 as needed, and directly the present invention. Flip 180 degrees to perform low work.
