Technical Field

The utility model relates to a conversion tool of an electric wrench, in particular to a drill chuck of the electric wrench.

Background

The electric wrench is widely applied in the fields of building construction, machining and the like by virtue of the advantages of high efficiency and rapidness. However, the conventional electric wrench can be used only for turning fasteners such as bolts, screws, etc., and cannot be applied to other types of tools such as electric drills, electric grinding wheels, etc. Therefore, in actual work, different types of power tools are required to accomplish different works, which also increases the labor intensity and purchase cost of the user.

The existing solution is to use a plurality of different types of power tools, which improves the working efficiency, but doing so requires a plurality of different power tools, which not only increases the cost, but also requires corresponding storage and maintenance. Another solution is to integrate the power wrench with other tools, but such built-in design power tools are bulky and experience poor, and increase the difficulty of use and maintenance. Therefore, there is a need for a simple, easy to use, compact, electric wrench drill chuck that allows one electric wrench to perform the functions of a wrench, an electric drill, and other tools, thereby improving work efficiency, reducing use and maintenance costs, and reducing the workload of the user.

Description of the embodiments

The following describes in detail the embodiments of the present utility model with reference to fig. 1-8.

Example 1: an electric spanner drill chuck, as shown in figure 1, comprises the following general core components: a collet sleeve 4, and a collet cap 1 mounted on the collet sleeve 4; referring to fig. 2, the lower end of the chuck sleeve 4 is a sleeve bottom 42; a hollow structure in the bottom 42 of the sleeve, which is obviously prepared for matching with the square rotating shaft 7 of the electric wrench; in short, the square rotating shaft 7 of the electric wrench can be inserted into the bottom part 42 of the sleeve;

referring to fig. 2, a hole is formed in the annular wall of the bottom 42 of the sleeve, and a limiter 43 is embedded in the hole; obviously, the purpose of embedding the limiter 43 in the hole is to limit the situation that the square rotating shaft 7 of the electric wrench is inserted into the hollow structure;

in a general embodiment, the limiter 43 is preferably a steel ball;

because the chuck base 3 is sleeved outside the sleeve bottom 42, the structure of the chuck base 3 can restrict the micro-motion of the steel balls in the holes; the micro-motion can ensure that when the square rotating shaft 7 of the electric wrench is inserted (the chuck base 3 is lifted upwards at the moment), the steel balls are recovered in the holes;

the bottom 42 of the sleeve is sleeved with the chuck base 3; and a spring seat 6 is sleeved outside the bottom 42 of the sleeve; the bottom end of the spring seat 6 is abutted against the inner bottom wall of the chuck base 3; the purpose of the spring seat 6, as shown in fig. 3, is to automatically reset when the chuck base 3 is lifted up by an external force;

thus, a lifting operation space is reserved at the bottom 42 of the sleeve on the chuck base 3; that is, when the chuck base 3 is lifted upwards, the steel balls are retracted, so that the square rotating shaft 7 of the electric wrench is inserted, when the external force of the chuck base 3 is released, the chuck base 3 is affected by the elastic force of the spring seat 6, the chuck base is automatically reset, the steel balls are ejected out of the holes at the bottom of the sleeve, and the square rotating shaft 7 of the electric wrench is limited and restrained.

Generally, the hollow structure is a square structure, and the square structure is internally matched with the square rotating shaft 7 of the inserted electric wrench;

the scheme also needs to be noted that: the hollow structure can also be round, and the round structure also falls into the protection scope of the present utility model.

Again, the above-described structure needs to be supplemented; the actual steel ball retraction belongs to the prior art, and the principles are adopted by the drill rod insertion and extraction of some conventional electric hammer and other tools; it is true that the prior art in the above description does not describe thoroughly.

The superstructure of this case is then:

the top end of the chuck sleeve 4 is internally provided with 2-5-valve clamping rods 2, and the clamping rods 2 of 2-5-valve are surrounded to form a clamp; the design structure is also the prior art in practice, and the traditional small electric hand drill clamping adopts the design;

the tail end of each clamping rod 2 is provided with a clamping rod thread 21; a clamping rod chute 41 which is matched with the shape of the clamping rod 2 is obliquely arranged in the clamping head sleeve 4.

A rotary disc 5 is sleeved outside the chuck sleeve 4, and an inner thread 52 is arranged on the inner wall of the rotary disc 5; the outer wall is provided with an external thread 51 in a circle in a ring shape; the internal thread 52 engages the rod thread 21. The external thread 51 of the rotary disk 5 is engaged with the thread teeth provided in the cartridge cap 1.

Referring to fig. 4 and 6, when the chuck cap 1 rotates (manual rotation by external force), the external thread 51 of the rotary disk 5 can be driven by the thread teeth arranged in the chuck cap 1 in a meshing manner, and the external thread 51 is meshed with the rod thread 21; therefore, the chuck cap 1 rotates, so that the clamping rods 2 can be opened and closed finally, and the articles such as the embedded drill rod and the like can be clamped.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. It will be understood by those skilled in the art that the present utility model is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present utility model, and various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined in the appended claims. The scope of the utility model is defined by the appended claims and equivalents thereof.
