The transmission rod is connected in the ball head cover in the sliding block through the ball head part, so that the assembly of the transmission rod and the sliding block is facilitated, and the connection of the transmission rod and the sliding block is more compact.

[0007] In particular, the two guide blocks matched with the sliding block are arranged on the mechanism frame corresponding to the sliding block, and the two guide blocks are provided with the two guide grooves matched with the sliding block. The two guide convex strips slidingly arranged in the two guide grooves are arranged on the two sides of the sliding block. The two guide blocks matched with the sliding block are arranged on the mechanism frame, so that the reliable movement of the sliding block on the mechanism frame is ensured, and the working reliability of the small punch press is improved.

[0008] In particular, the mounting hole for mounting the punch is arranged on the sliding block, the gland groove communicated with the mounting hole is arranged on the sliding block, the gland is arranged in the gland groove, and the clamping cavity for clamping the punch is formed between the gland and the mounting hole. The clamping cavity for clamping the punch is formed between the gland and the mounting hole of the sliding block, so that the assembly of the punch and the sliding block is facilitated and more convenient.

[0009] In particular, the touch screen is arranged on the intelligent control box. The touch screen is arranged on the intelligent control box, so that the user operation is facilitated and the use is more convenient. BRIEF DESCRIPTION OF DRAWINGS
