In another embodiment, the hole drilling driving mode of the driving device inside the machine body 12 is to drive the punch head 11 to rotate and advance, so as to drill holes in a drilling mode. Four support grooves 121 are arranged around the punch head 11 on the machine body 12, the support rods 2 are slidably arranged in the support grooves 121, and a support spring 23 connected with the bottom wall of the support rod 2 is fixedly arranged in the support groove 121. A second locking groove 122 communicating with the support groove 121 is arranged on the side wall of the machine body 12, the support rod 2 penetrates a plurality of first locking grooves 21 which can communicate with the second locking groove 122, and a locking rod 4 which can pass through the first locking groove 21 is slidably arranged in the second locking groove 122. A second magnetic suction block 124 is fixedly arranged on the inner side wall of the second locking groove 122, and a first magnetic suction block 42 is fixedly arranged at the end of the locking rod 4 away from the side wall of the machine body 12, which can be attached to and magnetically attracted to the second magnetic suction block 124. The machine body 12 is provided with a plurality of connecting bolts 31 and four connecting rods 3, and the connecting bolts 31 fix the two ends of the connecting rod 3 on the adjacent support rods 2 respectively. After the support rod 2 is fixed by the locking rod 4, the support rod 2 abuts against the surface to be punched when punching, so as to improve the stability of the handheld puncher 1, reduce the possibility of the machine body 12 deviating due to punching vibration, and improve the punching quality.

[0033] In order to improve the applicability, referring to Figure 2 and Figure 3The body 12 is provided with an auxiliary rod 41 fixedly connected with two locking rods 4 on the same side, and the top wall of the auxiliary rod 41 is provided with an auxiliary groove 411 for facilitating pulling. The locking rod 4 is provided with a sliding block 43 penetrating through the top wall and the bottom wall of the locking rod 4 and fixedly connected with the locking rod 4 by welding. The side wall of the support rod 2 close to the side wall of the body 12 is provided with two first sliding grooves 22 communicating with the first locking groove 21. The inner side wall and the bottom wall of the second locking groove 122 are both provided with a second sliding groove 123 communicating with the support groove 121.
