Because there is no tension in the constant force spring that pushes the nail, naturally, no nail can be driven.
The pushing device of the nail gun uses the constant force spring, because the constant force spring has the characteristic of keeping the constant force in the long stroke, and it can achieve a very high elasticity output in a very small device space. The constant force spring in the nail gun cannot be pushed too small, otherwise it will be difficult to drive the nail inside into the substrate, but it cannot be too large either, otherwise the substrate will be damaged and cracked.
So when it comes to choosing constant force springs, choose a spring manufacturer with good quality.

The constant force spring is made of stainless steel strip. The high-strength steel strip is shaped by specific spring production equipment. When it is straightened by external force, the spring will naturally roll back and produce elastic force. However, when our goal is achieved, it can return to the starting point specified by us after displacement. So do you know that constant...
Imagine, on the weekend of a busy work week, unloading from work, taking a hot bath, having a leisurely dinner, and when it's time to rest, draw the curtains to isolate the noisy world outside, and then, beautiful and beautiful Sleeping until you wake up naturally, this is not the most important thing for every office worker. However, for...
One of the biggest benefits of electric wheelchairs is the use of an electric drive that allows users to move freely even without having to push themselves manually or with human power. These wheelchairs are prepared for people in different situations, while allowing more people with inconvenient lives to regain their freedom. The electric wheelchair includes a mobile seat part,...
Transmission hoses and wires are necessary for automotive production and maintenance work, but they are time-consuming and labor-intensive to sort out after use. Another common problem is safety when handling them. This can cause serious injury if the operator is inexperienced. Bulky and unwieldy hoses are also an added risk, especially if they are too short for the job. This...
Traditional power springs and preloaded power springs are fabricated from spring steel bars to provide torque. Spring steel is a low alloy, medium carbon steel or high carbon steel with a very high yield strength. Objects made of spring steel can return to their original shape despite significant bending or twisting. Power springs use flat (unstressed) steel windings, while...
At about 10 am on the 16th, the "Shenzhou 13" manned spacecraft landed smoothly, and the three astronauts who had been on a business trip for half a year also returned safely, and the hearts of many people also fell to the ground. At the same time, Yang Liwei's voice that appeared in the live broadcast room also made many...
