[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] like Figure 1 The manual long-stroke press shown includes a base 1, on which a support rod 2 is vertically fixed. A support block 3, parallel to the base 1, is fixed to the support rod 2. A fixed rack 4 is vertically inserted into the support block 3. A gear 5 is installed inside the support block 3 and is rotatably connected via a rotating shaft 6. A handle 7, parallel to the gear 5, is fixed to the rotating shaft 6. The gear 5 and the fixed rack 4 mesh with each other via their teeth. A pressure head is located at one end of the fixed rack 4 at the bottom of the support block 3. By turning the handle 7, the rotation of the gear 5 is controlled, indirectly controlling the sliding downward pressure of the fixed rack 4. Depending on the needs of the operation, a larger diameter gear 5 can be used to reduce the operator's arm swing amplitude during operation.
