The two connecting rods 105 are arranged one in front of the other, and the connecting rods 105 are provided with threaded holes for installing the hand screws 106. The installation shaft 103 is fixed on the inner side of the connecting block 101, and is used for rotating and installing the handle 104. The two working rods 107 are fixed to one end of the two handles 104 through the two locking mechanisms 110. By loosening the two locking mechanisms 110, both of the working rods 107 can be retracted into the handles 104. One working rod 107 supports the first working end 108, and the other working rod 107 supports the second working end 109. When not in use, the two locking mechanisms 110 are loosened, and the two working rods 107 are retracted into the two handles 104, and then screwed. The hand screw 106 is turned to disengage the hand screw 106 from the connecting rod 105 away from the turning end, and finally the two handles 104 are rotated 90 degrees to make the two handles 104 close to each other and folded and stored, so that they can be folded when not in use for easy carrying; when needed, the two handles 104 are rotated 90 degrees to make the two connecting rods 105 close to each other and the two threaded holes overlap, and the hand screw 106 is turned to make the hand screw 106 pass through the two connecting rods 105, thereby locking the two handles 104, and finally the two working rods 107 are pulled out and locked with the two locking mechanisms 110, and then it can be used.

When the working rod 107 needs to be retracted into the handle 104, the locking block 115 is twisted away from the engagement block 114, the engagement block 114 is no longer pressed, and then the working rod 107 is pulled outward for a distance. The engaging block 114 is disengaged from the two limiting grooves 117, and then the working rod 107 is rotated so that the engaging block 114 is aligned with the engaging hole 116. Finally, the engaging block 114 and the working rod 107 can be passed through the engaging hole 116 and retracted together into the handle 104 until the movable magnet 112 is adsorbed on the fixed magnet 111. When it is needed, the working rod 107 is pulled to drive the engaging block 114 to move to the outside of the mounting block 113, and the working rod 107 is rotated so that the engaging block 114 is aligned with the two limiting grooves 117 and inserted. Finally, the locking block 115 is twisted so that the locking block 115 moves to press the engaging block 114. At this time, the working rod 107 is locked and cannot be moved anymore.
