[CN 201910245320.6] Pressure limiting manual press


[CN 201910245320.6] Title of a Pressure Limiting Manual Press: Application Number of a Pressure Limiting Manual Press: CN 201910245320.6 Applicant: Xu Xinzhen Application Date: 2019-3-28 Patent Type: Application for Invention The present invention specifically relates to a manual press. It is an object of the present invention to provide a pressure limiting manual press capable of limiting an upper limit of a pressure. The technical solution adopted by the present invention is: a pressure-limiting manual press, including a base and a pressing device, the pressing device is erected above the base through an inverted L-shaped support arm; the upper end of the connecting shaft passes through the end cover The outside is connected with the adjusting handwheel, and a limited pressure mechanism is arranged on the connecting shaft; the connecting shaft is composed of an upper half shaft and a lower half shaft, the pressure limiting mechanism comprises a plurality of vertical keyways with an isosceles trapezoid cross-section, which are uniformly arranged on the circumferential surface of the lower end of the upper half shaft. The invention can limit the upper limit of the pressure of the manual press and avoid the situation of excessive pressure.
