Description

Impact screwdriver structure improvement

This creation is about "improvement of impact driver structure", especially the creation of an impact driver that uses a shock-vibration method to unscrew the screw that is too tight or has a tooth.

The conventional impact driver includes a grip, a spring, a rotating shaft and a latch, and one end of the grip has an axial coupling groove and a V-shaped pin hole radially passing through the set of slots. One end of the rotating shaft is provided with a radial insertion hole, the rotating shaft can compress the spring into the assembly groove of the grip, and the insertion hole thereof corresponds to the pin hole on the grip, so that the pin can pass through the grip The pin hole is with the jack of the shaft.

The conventional impact driver structure can be easily and effortlessly removed for a screw that is difficult to unscrew; when the user wants to remove the screw with the screw head as a hexagonal hole, the use of a hexagonal hole is used. The joint is assembled on the rotating shaft, and a hexagonal screwdriver is installed in the hexagonal hole of the adapter, and the hexagonal screwdriver is used to align the screw with the hexagonal head to operate the impact driver. Function to unscrew and remove it.

Wherein, when the user wants to remove the screw with the outer hexagonal screw head, it is assembled on the rotating shaft by using a hexagonal hole adapter, and the hexagonal hole of the adapter is used to align with the outer hexagon. The screw of the angled head can be unscrewed and removed by the operation function of the impact driver.

Although the aforementioned conventional impact driver is provided for the user to screw it difficult to unscrew Take out, however, it is necessary to assemble the screwdriver with the adapter of the hexagonal hole with a smaller aperture, and the adapter of the hexagonal hole with a larger aperture, so that the screw with the head of the hexagonal hole can be separately The screw of the outer hexagon head is removed, which is not only difficult to assemble and disassemble, but also requires a lot of adapters, which is not only costly, but also consumes a lot of torque output through the adapter, which is extremely labor-intensive and portable. Inconvenience; Therefore, the lack of the use of the impact driver mentioned above is necessary to further improve it.

In view of the fact that there are still some improvements in the current structure, the creator has been engaged in the multi-year production and sales experience of related products, and has been thinking about the existing problems and pondering the improvement methods. After many improvements and tests, the author finally created an impact. The structure of the screwdriver is improved.

First, please refer to the first to seventh figures, which is an impact driver structure improvement, which is composed of a grip 10, a bushing 11, an elastic member 12, a rotating shaft 13 and a latch 14. The first end of the grip 10 has an axial receiving groove 101, and the periphery of the grip 10 is provided with a pin hole 102 radially passing through the receiving groove 101, the pin The holes 102 are triangular, such that the pin holes 102 have a first position 103 and a second position 104 (as shown in the fourth figure), and the grip 10 is located on the outer periphery of the pin hole 102 with a ring 105. The recess 105 is provided for the bushing 11; and the receiving slot 101 is provided for the elastic member 12 and the rotating shaft 13. The outer peripheral edge of the rotating shaft 13 is provided with a radial through hole 131. And the rotating shaft 13 is pressed against the elastic member 12, so that the insertion hole 131 of the rotating shaft 13 can be located at the pin hole 102 of the grip 10, and the pin 14 is used to pass through the pin hole 102 and the insertion hole 131 (such as The first picture shows); It should be noted that the rotating shaft 13 has an outer quadrangular joint portion 132 at one end of the insertion hole 131, and the set of joint portions 132 is provided for the socket assembly 20, and the set of joint portions 132 One end has an axial hexagonal hole 133, and the set position of the set of joints 132 has a radial positioning hole 134 communicating with the hexagonal hole 133, and the positioning hole 134 is provided for a magnetic member 30. The socket assembly 20 is composed of a hexagonal mandrel 21 and a sleeve 22, and the mandrel 21 is mounted on the hexagonal hole 133 of the set of joint portions 132, and the sleeve 22 is oriented. One end of the set of joints 132 has a first hole 221 that is sleeved in the set of joints 132, and the sleeve 22 has a second end that is open to the first hole 221 at one end of the first hole 221 The hole 222 is mounted on the set of joint portions 132 such that the mandrel 21 can be inserted into the second hole 222 from the first hole 221.

The elastic member 12 is a spring.

The magnetic member 30 is a magnet.

The first hole 221 of the sleeve 22 is an inner square hole.

The second hole 222 of the sleeve 22 is a hexagon socket.

It may further include a fastener 40. The inner edge of the hexagonal hole 133 of the set of joints 132 has an inner ring groove 135, and the inner ring groove 135 is for the fastener 40 to be set.

The fastener 40 is a C-shaped buckle.

With the above combination, please continue to refer to the first to seventh figures. This creation is mainly applied to screws that are difficult to unscrew or lock; wherein, when the user wants to screw the head 51 When the hexagonal screw 50 is removed, the sleeve 22 is mounted on the set joint. The portion 132, because the second hole 222 of the sleeve 22 is a hexagonal hole, can be set on the outer hexagonal screw head 51, and since the spindle 21 extends from the first hole 221 into the second hole 222, The end surface of the mandrel 21 is allowed to abut against the top surface of the screw head 51, so that the end surface of the sleeve 22 can be prevented from contacting the surface of the workpiece 60 (as shown in FIG. 5) to ensure that the workpiece 60 is avoided when the screw 50 is unscrewed. The wound on the surface and the torsion force during the application of force are applied. After that, the user holds the grip 10 with the hand, and then hits the top of the grip 10 with the other hand (not shown), and the grip 10 is received. When the force is applied, the sleeve 22 will be pressed against the screw head 51, so that the sleeve 22 can form a force compressing the elastic member 12, and the bolt 14 will be displaced along the triangular pin hole 102, displaced from the first position 103 to The second position 104, so that the sleeve 22 can rotate along the pin hole 102, at this time, the downward pressure can be generated, and the effect of the rotation can be achieved, and then the screw 50 can be gradually unscrewed or locked, so that The operation mode is simple and convenient, and the utility model is practical; as for the mandrel 21, additional fittings can be made according to the sleeve 22 of different lengths to expand Use range.

Wherein, when the user wants to remove the screw 50 with the screw head 51 as a hexagonal hole (as shown in FIG. 7), the mandrel 21 of the hexagonal hole 133 installed in the group joint portion 132 can be directly used. Aligning the screw head 51 of the hexagon socket, the screw 50 with the hexagon socket head 51 can be easily removed by the above-mentioned operation method of the impact driver, and the screw can be removed without any effort. 50 rotation, which has better labor-saving operation effect, and can not only screw the screw with hexagon socket at the beginning, but also screw with hexagon socket at the beginning. It can be unscrewed without multiple sets of tools. The purpose of the screw is that the overall operation mode is simple and easy, and it is convenient to carry and practical.

In summary, the creation of the impactor structure is improved, effectively improving the shortcomings of the conventional structure, and the main technical means of this creation are not found in any related publications. In the meantime, Chengcheng meets the application requirements for new patents, and submits an application in accordance with the law.
