Description

Through screwdriver structure

technical field

The utility model relates to a through-type screwdriver structure, which utilizes the characteristics of light weight and knock resistance of the through-type screwdriver to increase the function of percussion and rotation, thereby making it easier to assemble and disassemble the locking component when the tool is used for percussion.

Background technique

Please refer to Fig. 1 and Fig. 2, the commonly used screwdrivers are directly molded on the plastic handle 1 with sockets 3 with slots 2 on both sides, and another screwdriver bar 4 has wings 5 on both sides, so that the screwdriver can be The rod 4 is forced into the handle 1, and is engaged with the slot 2 by the fin 5, so that when the handle 1 rotates, it can drive the screwdriver rod 4 to rotate at the same time, so as to carry out the disassembly operation of the locking assembly; however, some Locking components (such as bolts) are damaged due to corrosion or thread, and cannot be removed directly with a general screwdriver. They must be knocked and vibrated before they can be rotated with a screwdriver. As shown in Figures 1 and 2 The handle 1 of the screwdriver is made of plastic in order to provide the user with easy-to-operate effects, and it cannot be used for knocking and vibration. Please refer to Fig. 3 and Fig. 4, the handle 6 of this kind of through-type screwdriver is still made of plastic, and has the characteristics of easy operation and use, but when the handle 6 is formed, a step-shaped The metal striking head 7 covers the small-diameter end 8 of the front end of the striking head 7 in the handle 6, the small-diameter end 8 of the striking head 7 is provided with a corner hole 9, and the shaft of the other screwdriver rod 10 is angular When the handle 6 is injection molded, one end of the rod body of the screwdriver rod 10 is inserted into the small-diameter end corner hole 9 of the striking head, and is connected with the metal striking head 7, and after the handle 6 is formed, it is coated on the handle 6, The handle 6 can drive the striking head 7 and the screwdriver rod 10 to rotate at the same time during operation and use. Since the rear end of the through-type screwdriver has a metal striking head 7 that is resistant to knocking, it can be used when the locking assembly that is not easy to rotate and dismantle is used. , can be knocked and vibrated from the rear end of the handle, and linked to the connected screwdriver rod 10, and then can be used for knocking and vibration, and the handle 6 still has the characteristics of being easy to hold. Although the through-type screwdriver can be used for percussion, in the actual use process, even after the corroded bolt is percussed, it still needs to exert a considerable force to turn it, and it still remains motionless. If there is a bolt that is extremely difficult to remove, the industry will design a special removal tool. Please refer to Fig. 5, Fig. 6, this special percussion tool, its handle 11 is made by metal material turning as a whole, so can be used for percussion, its front end is provided with a set of holes 12, on the side ring wall of opposite sleeve hole 12 Two opposite V-shaped grooves 13 are provided. After the spring 14 is sleeved in the sleeve hole 12, a tool head 15 is inserted, and a plug 16 is used to penetrate the perforation 17 and the V-shaped groove 13 of the tool head 15. The tool head 15 That is to say, the spring 14 can be compressed, and move along the V-shaped groove 13 by the pin 16, so when the handle 11 is knocked, the tool head 15 can impact and vibrate the bolt, and at the moment of impact, the tool head 15 will be affected The reaction force compresses the spring 14. At this time, the pin 16 moves down along the V-shaped groove 13 to the bottom point, and the elastic force of the spring 14 makes the pin 16 move upward (as shown in Figure 7), and the V-shaped path Therefore, at the moment of striking, it can also produce the effect of turning, making the bolt easier to disassemble; but the striking tool is made of metal because the handle needs to be struck. It is made, so it is very cumbersome. When the follow-up rotation operation after knocking is completed, it is difficult for ordinary people to carry out the continuous rotation operation with a load, and it is necessary to replace the generally lighter screwdriver tool (such as the screwdriver in Figure 2). Therefore, when using It is difficult to take into account the purpose of being light and easy to operate.
