Detailed Description

Example 1:

referring to fig. 1-4, a fastener includes a body 1 and an axe portion 2.

The body 1 comprises a head part 3 connected with a driving device and a rod part 4, and the head part 3 is connected with one end of the rod part 4. In the present embodiment, the head 3 is embodied as a rectangular parallelepiped, that is, the cross-sectional dimension of the head 3 is rectangular. The head 3 is mainly connected and matched with driving equipment, and the driving equipment can generate impact effect on the head 3, so that the fastener is integrally inserted into a fixed object, and the driving equipment can be electric equipment or pneumatic equipment.

The rod portion 4 is a smooth cylinder, and one end of the rod portion 4 is connected to the head portion 3, so that the rod portion 4 and the head portion 3 are integrally formed in the present embodiment, that is, the rod portion 4 and the head portion 3 are made of the same material. The other end of the rod part 4 is provided with a first protrusion 41 connected with the axe-shaped part 2, and the first protrusion 41 extends towards one side of the axe-shaped part 2.

One end of the axe-shaped part 2 is provided with a first concave cavity 21 matched with the first bulge 41, and the first bulge 41 extends into the first concave cavity 21 so as to realize the connection and fixation of the axe-shaped part 2 and the rod part 4. Here, the first protrusion 41 and the first cavity 21 are fixed by welding, and in this embodiment, the first protrusion 41 and the first cavity 21 are preferably welded by brazing.

The blade part 5 is arranged at the other end of the axe-shaped part 2, the blade part 5 is formed by connecting a first side surface 51 and a second side surface 52, the first side surface 51 and the second side surface 52 are both arranged in an inclined plane, and the connecting position of the two is the position of the blade part 5. The first side surface 51 and the second side surface 52 have different inclination angles, so that the blade 5 is eccentrically disposed with respect to the center of the axe-shaped portion 2. Adopt two sides to form blade 5 to realize eccentric effect, make holistic impact more stable, the angle that two sides slopes here can be selected according to actual demand.

Further, the axe-shaped part 2 is made of alloy material. The axe-shaped part 2 is made of alloy materials, so that the overall hardness is further improved, and the fastener can easily enter a fixed object.

Adopt this kind of structure to set up, for prior art's structure, adopt the eccentric settings of cutting part 5, make cutting part 5 after entering into the fixture, form certain splitting effect, thereby make 4 better stretches into in the fixture of pole portion, thereby realize the fixed effect of fastener, and simultaneously, because drive arrangement's impact force is great, so through the cooperation of cutting part 5 with the impact force, make difficult emergence excessive splitting in the fixture, and the fastener in this application is mainly to the harder fixture of texture, this kind of fixture is after splitting, along with the stretching into of axletree portion 3, its open end can shrink and form certain stress, stress can carry out the centre gripping towards pole portion 4, thereby the fixed effect of centre gripping of fastener has been formed.
