Description

TECHNICAL FIELD

[0002] In the field of straight jump knives, straight jump knives are widely used in scenes such as outdoor exploration, emergency rescue, daily cutting, etc. due to their unique pop-up design. However, the existing straight jump knives generally have the problem of poor structural stability. When the blade pops up, it is easy to shake during use due to the lack of effective anti-shaking mechanism, which not only reduces the cutting accuracy and affects the use experience, but also may cause accidental injury due to blade shaking during operation, especially when dealing with delicate work or in emergency situations, the risk brought by such shaking is more prominent.

[0003] At the same time, the existing straight jump knives also have defects in the design of the elastic puller assembly and the elastic clamping assembly. The structural design of the elastic puller assembly may result in inaccurate and smooth control of the blade popping up or retracting, and poor operation feel; and the elastic clamping assembly cannot ensure that the blade is stably fixed in the popped-up or retracted state, and may easily pop up or retract unexpectedly, greatly affecting the safety and reliability of the straight jump knife. These problems limit the application and development of straight jump knives in more fields, and urgently need to be solved through innovative design. UTILITY MODEL CONTENTS
