As the technical proposal of the utility model for the step , the lock head is made of stainless steel.

As the technical proposal of the utility model for the step , the needle head is a silver steel needle.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the silver steel needle has high hardness and good toughness, is durable and is not easy to break and bend;

2. the stainless steel lock has various specifications, and locks with different apertures can be manufactured according to actual requirements;

3. the silver steel needles have various specifications, the silver steel needles with different diameters can be selected according to actual needs, and the length of the silver steel needles can be freely cut;

4. if the silver steel needle breaks in the use process, the needle can be replaced, and the lock head can be reused, so that the cost is greatly saved.

Detailed Description

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", and the like, indicate the orientation or positional relationship indicated based on the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Thus, a feature defined as "", "second" may explicitly or implicitly include or more of that feature.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "fixed," and the like shall be construed to , for example, as being fixedly connected, detachably connected, or in a body, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediary, connected between two elements, or interacting between two elements.

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

The replaceable multi-specification universal knocking tool comprises a bolt 4, a tapered end 2 connected with the bolt 4 is installed at the end of the bolt 4, a needle head 1 is installed in the tapered end 2, a stop screw 3 used for fixing the needle head 1 is further installed in the tapered end 2, the tapered end 2 and the bolt 4 are fixedly connected through a wrench and pliers during installation, then the needle head 1 is fixed through the stop screw 3 after being inserted into a proper depth, the proper tapered end 2 and the needle head 1 can be replaced according to actual use conditions, the needle head 1 can be replaced even if the needle head 1 is broken during working, the needle heads 1 with different diameters can be replaced, detachable connection is adopted, the practicability is better, and the cost is greatly saved.

, in order to facilitate installation, the bolt 4 is a hexagon socket head cap screw, which facilitates installation of a hexagon socket head cap wrench, the tapered end 2 is provided with a thread groove matched with the bolt 4, which facilitates the tapered end 2 to be matched and fixed with the bolt 4, the tapered end 2 is provided with an installation hole matched with the needle head 1 far away from the bolt 4 , which facilitates installation of the needle head 1 and replacement of the needle head 1, the side surface of the tapered end 2 is also provided with a thread hole communicated with the installation hole, which is matched with the stop screw 3, the needle head 1 is fixed by screwing the stop screw 3 into the thread hole, when the needle head 1 is broken or the needle heads 1 with different diameters need to be replaced, the operation is convenient, and the tapered end 2 can be reused.

Example 2

The embodiment is optimized by steps on the basis of the embodiment 1, the lock head 2 is made of stainless steel and long in service life, the lock heads 2 with mounting holes of different apertures can be manufactured according to actual use requirements, and replacement is convenient, and the needle head 1 is a silver steel needle which is high in hardness, good in toughness, durable, not easy to break and not easy to bend.
