The stroke chamber 1031 is designed to limit the stroke of the axial movement of the drilling mechanism 101 (i.e., the stroke of the lifting movement of the drill bit), and the depth of the drilled hole can be determined by using the stroke to obtain the required hole depth.

Specifically, for example, a wood board 10mm thick needs to be perforated, and the hole depth of the hole is 8mm, so that 2mm needs to be reserved. When the rated stroke of the stroke cavity 1031 is 8mm, drilling is directly carried out; if the stroke of the stroke chamber 1031 is greater than the distance between the drill bit and the processing platform, a corresponding spacer is added to the stroke chamber 1031 to offset the exceeding stroke; that is, the drill bit of the drilling mechanism 101 abuts against the product, at this time, a gasket with the thickness of 2mm is placed on the travel cavity 1031, and then drilling is performed, so that a blind hole with the depth of 8mm can be obtained, and drilling with the accurate depth is realized.

Further, as shown in fig. 3, the foot pad 30 may be mounted on the bottom surface of the workbench 10, and the foot pad 30 pair may protect the bottom surface of the workbench 10, so as to achieve the effect of separating from the placement surface (ground or desktop), thereby improving practicality.
