Detailed Description

As shown in fig. 1 to 3, the present embodiment discloses an expansion screw or chemical bolt quick impact socket, which includes a head 1, a spring 2, an impact hammer 3 and a sleeve 4; the club head 1 comprises an upper club head 101 and a lower club head 102, a limiting part 5 is arranged at the joint of the upper club head 101 and the lower club head 102, the lower club head 102 extends into one end of the sleeve 4, an impact hammer 3 is arranged at the end part of the lower club head 102 positioned in the sleeve 4, the spring 2 is sleeved on the lower club head 102, one end of the spring 2 is abutted against the top of the sleeve 4, and the other end of the spring 2 is abutted against the lower end of the limiting part 5.

In this embodiment, the upper club head 101 is used as a first force-receiving component during striking, which transmits impact force to the lower club head 102, and the lower end of the lower club head 102 drives the impact hammer 3 to move downward, wherein the lower end of the sleeve 4 is sleeved on a nut of a bolt or screw to be struck, so that the impact force is formed on the nut when the impact hammer 3 impacts downward, and the spring 2 is compressed by force during striking and can assist the lower club head 102 to move upward to return to its original position when striking is completed.

Preferably, the sleeve 4 has a downwardly open U-shaped configuration.

Different from prior art, sleeve 4 in this embodiment only has decurrent opening, and its upper portion has seted up the mounting hole for installation impact hammer head 3, and inside lower part pole head 102 stretched into sleeve 4 through the mounting hole, sleeve 4's structure made impact hammer head 3 to slide in can following sleeve 4, and can't upwards break away from sleeve 4 through the mounting hole.

Preferably, the sleeve 4 is an inner hexagonal sleeve 4.

In a specific embodiment, in order to meet the use effect, the shape of the inner corner of the device can be changed and arranged as required.

Preferably, the upper head 101 and the lower head 102 are formed integrally.

In the embodiment, in order to avoid the unstable condition of split type structure junction to lead to the atress conduction influenced, set up it into integrated into one piece structure.

Preferably, the upper blade head 101 is provided with a holding notch 7.

The clamping slot 7 is used for connecting with an external driving device.

Preferably, a ball 6 is embedded in the side surface of the impact hammer head 3, and the outermost side of the ball 6 is abutted against the inner wall of the sleeve 4.

In the embodiment, the design of ball 6 can reduce the frictional force of strikeing tup 3 and sleeve 4 inner wall for frictional force consumes and diminishes, more does benefit to the embodiment of beating the effect.

Preferably, the upper head 101 has a circular or square cross-section at its upper end.

Preferably, the impact hammer head 3 is a magnetic head structure with magnetism.

Preferably, the limiting part 5 is connected with the club head 1 through thread fit and is used for detaching or adjusting the loosening force of the spring 2.

While embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that: various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
