Description

Technical Field

[0001] The utility model relates to a non-return type hand press in the technical field of hand presses, in particular to a hand press with a rack non-return mechanism. Background Art

[0002] The utility model relates to a hand press machine which prevents the hand lever from automatically rebounding. When a standard hand press machine is used manually to press a product, it is unknown whether it has been pressed to the bottom dead point. A hand press machine with a rack non-return mechanism must be pressed to the bottom dead point before it can be returned, thereby ensuring the pressing accuracy of the product. When a standard hand press machine is used manually to operate the handle, there is a possibility that the handle may slip out of the hand, and there is a risk of bruises due to automatic rebound without a non-return mechanism. Therefore, we provide a hand press machine which can accurately adjust the lowest pressing point and has a non-return function.

[0003] After searching, the existing Chinese patent publication number is CN201710402359.5. The utility model is a hand press with a rack check mechanism, including a shell, the front section of the shell is provided with a through hole 1 on the upper, lower, left and right, the middle section of the through hole 1 is provided with a groove 1, and a fixed plate 1 is slidably connected in the through hole 1, the rear section of the shell is provided with a through hole 2 on the upper, lower, left and right, the middle section of the through hole 2 is provided with a groove 2, and a fixed plate 2 is slidably connected in the through hole 2, and the end of the shell is provided with a through hole 3 on the upper, lower, left and right, respectively, and the middle section of the through hole 3 is provided with a groove 3, and a pull rod is slidably connected in the through hole 3, and the front and rear ends of the shell are respectively provided with an outlet hole and an inlet hole. The present invention has a simple structure and is easy to operate. The processing wire harness enters from the inlet hole at the rear end of the present invention and extends out from the outlet hole. The fixed plate 1 fixes the wire harness. After pressing the pressing plate to a suitable position, the pull rod can fix it. When the use is finished, the pull rod is pulled out to retrieve the wire harness.
