Screwdriver with knocking function

Abstract

The utility model relates to the technical field of screwdrivers, in particular to a screwdriver with a knocking function, which comprises a handle and a screwdriver rod fixedly connected in the handle, a knocking part is arranged at one end of the handle, a limit gasket is arranged in the handle, the screwdriver rod is fixedly connected in the limit gasket, and the knocking part is arranged on the screwdriver rod. A gap is formed between the end part of the cutter bar and the knocking part; the electric screwdriver has the advantages that during actual use, the distance is reserved between the knocking part and the screwdriver rod, so that the screwdriver rod is separated from the knocking part, and when the knocking part is used for knocking an electrified object, the screwdriver rod can be prevented from being electrified; meanwhile, when the knocking part is used for knocking, the screwdriver rod is limited through the limiting gasket, the contact area between the screwdriver rod and the handle is increased, and therefore the screwdriver rod is prevented from penetrating out of the handle in the knocking process.

Description

Technical Field

[0001] The utility model relates to the technical field of screwdrivers, in particular to a screwdriver with a knocking function. Background Art

[0002] As a common tool, screwdrivers are widely used in various fields such as machinery, electronics, and home furnishing. With the development of technology and the diversification of user needs, the functions of screwdrivers are also constantly expanding and improving. Among them, screwdrivers with knocking functions are favored by the majority of users because they can solve operational problems in certain specific scenarios.

[0003] The common screwdrivers with knocking function on the market usually have a knocking cap installed on the screwdriver bar; however, this design also has some obvious problems.

[0004] In order to prevent the knife bar from coming out of the handle due to inertia when striking, the striking cap and the knife bar are usually fixed together. Therefore, when striking a charged object, the knife bar will also be charged. This not only increases the risk of operation, but also may threaten the safety of the user. This safety hazard is particularly prominent in occasions such as electrical and electronic equipment that require frequent live operations.

[0005] Therefore, a screwdriver with a knocking function is needed to overcome the occurrence of the above problems. Utility Model Content

[0006] In order to solve the above problems, an embodiment of the utility model provides a screwdriver with a knocking function, which achieves the purpose of solving the problems raised in the background technology by separately arranging the knocking part and the tool rod.

[0007] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: a screwdriver with a knocking function, comprising a handle and a tool rod fixedly connected to the inside of the handle, a knocking part is arranged at one end of the handle, a limiting gasket is arranged inside the handle, the tool rod is fixedly connected to the inside of the limiting gasket, and a distance is arranged between the end of the tool rod and the knocking part.

[0008] As a further improvement of the above technical solution:

[0009] The knocking part is a metal knocking cap or a structure integrally formed with the handle.

[0010] The knocking part is provided with anti-slip grooves.

[0011] An anti-roll groove is arranged at the end of the handle.

[0012] The outside of the knife rod is provided with a groove, and the outside of the groove is sleeved with a sleeve.

[0013] The beneficial effects of the embodiments of the utility model are:

[0014] In actual use, a distance is provided between the striking part and the knife rod, so that the knife rod and the striking part are separated, and the knife rod can be prevented from being charged when the striking part is used to strike a charged object; at the same time, when the striking part is used to strike, the knife rod is limited by a limiting gasket to increase the contact area between the knife rod and the handle, thereby preventing the knife rod from passing through the handle when striking.

[0019] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0020] See also Figures 1 to 3 The utility model discloses a screwdriver with a knocking function, comprising a handle 1, a shank 2 fixedly connected to the inside of the handle 1, a knocking portion 3 is arranged at one end of the handle 1, a limiting spacer 4 is arranged inside the handle 1, the shank 2 is fixedly connected to the inside of the limiting spacer 4, and a distance is arranged between the end of the shank 2 and the knocking portion 3;

[0021] In actual use, a distance is provided between the knocking part 3 and the knife rod 2, so that the knife rod 2 and the knocking part 3 are separated, and when the knocking part 3 is used to knock a charged object, the knife rod 2 can be prevented from being charged; at the same time, when the knocking part 3 is used to knock, the knife rod 2 is limited by the limiting gasket 4 to increase the contact area between the knife rod 2 and the handle 1, thereby preventing the knife rod 2 from passing through the handle 1 when knocking.

[0022] As a further illustration of this application:

[0023] The striking part 3 is a metal striking cap or a structure integrally formed with the handle 1 ; the metal striking cap can be fixed to one end of the handle 1 ; and the striking part 3 can be directly formed when the handle 1 is injection molded.

[0024] As a further illustration of this application:

[0025] The knocking part 3 is provided with anti-skid grooves to prevent sliding when the knocking part 3 is knocked.

[0026] As a further illustration of this application:

[0027] The end of the handle 1 is provided with an anti-roll groove 7; the anti-roll groove 7 can prevent the screwdriver from rolling, thereby avoiding the situation where objects fall from high altitude due to the rolling of the screwdriver during high-altitude operations.

[0028] As a further illustration of this application:

[0029] A groove 5 is provided on the outside of the shank 2, and a sleeve 6 is provided on the outside of the groove 5; when the screw is turned by the cutter head at the end of the shank 2, when the torque is too large, the groove 5 is deformed for buffering due to its small diameter, thereby avoiding damage to the cutter head of the shank 2;

[0030] The sleeve 6 can be provided in different colors and shapes, so that the user can distinguish the specific specifications of the screwdriver and use screwdrivers of different specifications conveniently.

[0031] As a further illustration of this application:

[0032] The outer surface of the handle 1 is provided with Figure 3 The anti-skid groove 8 shown can increase the friction between the hand and the handle 1 when the user grasps the handle 1, thereby achieving an anti-skid effect.
