[0026] A limiting block 2 is fixedly connected to the front of the hand-held rod 1, and a rotating block 21 is in contact with the right side of the limiting block 2. There are two limiting blocks 2, and the two limiting blocks 2 are symmetrically arranged with the rotating block 21 as the center. A connecting groove is opened on the top of the connecting piece 24, and the connecting groove is adapted to the flat position 23.
[0027] An M8 ball screw 3 is fixedly connected to the bottom of the connecting piece 24, a limiting groove is opened on the front of the hand-held rod 1, and the limiting groove is adapted to the M8 ball screw 3. A cushion block 31 is fixedly connected to the front of the disassembly plate 13, and a sliding groove 32 is opened on the top of the connecting block 12.
[0028] The top of the connecting rod 42 contacts the fixing rod 4 , the middle of the fixing rod 4 is sleeved with an anti-slip rubber sleeve 41 , the top of the fixing rod 4 is fixedly connected to a fixing column 44 , and a disassembly ring 43 is fixedly connected to one side of the outer surface of the fixing rod 4 close to the fixing column 44 .
[0029] A movable groove 5 is provided on the top of the connecting rod 42, and there are two movable grooves 5. The two movable grooves 5 are symmetrically arranged with the connecting rod 42 as the center. A limiting block 2 52 is fixedly connected to the outer surface of the connecting rod 42, and there are two limiting blocks 2 52. The two limiting blocks 2 52 are symmetrically arranged with the fixed column 44 as the center. The two fixed columns 44 are adapted to the two movable grooves 5. A spring 51 is fixedly connected to the bottom of the connecting rod 42.
