Screw installation device

Abstract

The invention relates to the field of furniture assembling, and discloses a screw installation device. The screw installation device comprises a first cavity, and a first through hole and a second through hole are formed in the first cavity. An ignition element is arranged inside the first through hole, and a fuse head is arranged at the ignition end of the ignition element. The first cavity communicates with a second cavity through the second through hole, and a male die is slidably connected into the second cavity. Rotating blades are connected to the male die, and a hole is formed in the second cavity. The hole is arranged in the sliding path of the male die, and a female die is connected to the second cavity. A screw hole communicating with the hole is formed in the female die, and an elastic element is arranged on the side, close to the male die, of the female die. According to the scheme, a screw is arranged into the screw hole, the ignition element is electrified, the male die is pushed by the shock wave generated by the combustion of the fuse head to rotatably move forwards at a high speed, then the screw is impacted at a high speed by rotating of the male die, and the screw is rotatably injected into an object at a high speed. Compared with the prior art, the screw installation device is faster in installation, and easier to operate.

Description

technical field [0001] The invention relates to the field of furniture assembly, in particular to a screw installation device. Background technique [0002] The connecting screw consists of two parts, the head and the shaft. It is mainly used in occasions where the connection is not frequently disassembled and the force is not large. It is a connection that only needs screws (and sometimes washers) instead of nuts. Therefore, the structure Simple. At present, electric screwdrivers are mainly used to lock the screws. Since there is no auxiliary tool to fix the position of the gesture when holding an electric screwdriver, it is easy to cause insufficient hand-holding force and cause the screwdriver head and the screw head to slip. The attachment is not tight, and the problem of scratching the surface of the object. [0003] The patent document whose application number is 201110048879.3 discloses a screw installation device, which includes a base plate, positioning nails, str...

AI Technical Summary

Problems solved by technology

This solution uses strong magnetic steel to transmit magnetism to the screw through a magnetic screwdriver, and can automatically guide the screw into the screw hole to absorb and fix it. The structure is relatively simple, and the production is more convenient and practical; but there are also certain shortcomings: it needs Fix the parts on the device with positioning nails first, and then use a socket wrench to install the parts on the parts with nuts. Manual operation is required, the installation speed is slow, and the operation is more complicated
