[0032] The support rod 5 is fixed to one side of the first support rod 203 and the second support rod 206 by the first positioning screw 3 and the top rod 402.
[0033] A marking mechanism 1 is connected to the top of the base 2, such as... Figure 3 , Figure 4 As shown, the marking mechanism 1 includes a pressure rod 110 and a slider 101 connected to the base 2. The upper end of the slider 101 is provided with a support shaft 105. A rotatable upper support sleeve 106 and a lower support sleeve 118 are fitted onto the support shaft 105. The upper support sleeve 106 and the lower support sleeve 118 are connected by a synchronous rod. An upper telescopic rod 111 is inserted into the end of the upper support sleeve 106, and a lower telescopic rod 119 is inserted into the end of the lower support sleeve 118. Locking bolts 116 are provided on the side walls of both the upper support sleeve 106 and the lower support sleeve 118. The pressure rod 110 passes through the upper telescopic rod 111 and the lower telescopic rod 119.
