Detailed Description

The present invention will be further described with reference to the following embodiments, which are intended to illustrate the principles of the present invention without limiting the present invention in any way, and the present invention is not beyond the scope of the present invention.

With reference to the attached drawings.

Fig. 1-4 show an embodiment of the present invention, which is composed of a hammer head 1 and a hammer handle 2. The connection mode of the hammer head 1 and the hammer handle 2 is wedge fastening connection. The hammer handle is made of rubber, and scales of 25cm are printed on two sides of the hammer handle. The middle of the hammer head 1 is provided with an inertia force application mechanism which is composed of a balance weight 6, an upper guide rail connecting rod 7, a lower guide rail connecting rod 8, a front spring 9 and a rear spring 10. The counterweight 6 is made of cuboid alloy and is fixed on the hammer head by a front spring 9 and a rear spring 10 with proper elastic coefficients. The upper and lower parts of the balance weight are respectively connected with an upper guide rail connecting rod 7 and a lower guide rail connecting rod 8, the guide rail connecting rods are positioned in the guide rails inside the hammer head, and lubricating oil can be added at the position of a lubricating oil hole 11 in daily use to enable the inertial stress application mechanism to well slide. The position from the inertia force application mechanism to the hammer face 13 is provided with a nail groove 4, and the middle part of the nail groove 4 is provided with a magnet 5. The lower part of the hammer surface 13 is a smooth spline curve, and the upper part of the hammer surface is flush with the top of the nail groove 4 and is a plane. The hammer surface 13 is fully distributed with small convex points.

When the utility model is used, as shown in fig. 1, the nail 12 is firstly placed in the nail groove 4, and the nail 12 is adsorbed by the magnet 5. In the first hammer operation, the weight 6 in the inertial force applying mechanism is first moved forward under inertia from a force balance position between the

springs

9 and 10 to a position shown in fig. 2. At this time, the hammered body is subjected to the inertial additional force exerted by the inertial force-adding mechanism in addition to the normal hammering force of the hand hammer. At this moment, the action point of the inertia force can not be deviated by the upper guide rail connecting rod 7 and the lower guide rail connecting rod 8, the front end of the upper guide rail connecting rod 7 directly impacts the nail cap of the nail 12, and the first hammer is enabled to have better hammer force and more accurate positioning. After the hammering has ended, the counterweight 6 is displaced back from the position in fig. 2, in which case the instantaneous resilience of the hammering action can be reduced.
