Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Example one

Referring to fig. 1-3, this embodiment provides an electric screwdriver convenient for replacing screwdriver bits, which includes an electric screwdriver main body 1, generally used screwdriver bits are all fixed by direct insertion, and this way is convenient to detach and replace, and only needs to be pulled out with effort, but this has the problem of insufficient firmness of installation, so that the screwdriver bits are easily separated from the connector, resulting in the condition that the screwdriver bits cannot be used, therefore, the lower end of the electric screwdriver main body 1 is fixedly connected with the connecting frame 2, the lower end of the connecting frame 2 is fixedly connected with the connecting block 21, the connecting groove 22 is formed in the connecting block 21, and the connecting groove 22 is clamped with the mounting block 41, the lower end of the mounting block 41 is fixedly connected with the screwdriver bits 4, one side of the mounting block 41 is fixedly connected with the inserting block 42, the lower end of the inserting block 42 is fixedly connected with the fixing block 43, the spring 3 is fixedly connected in the connecting groove 22, and the lower end of the spring 3 is fixedly connected with the limiting block 31.

When the device is used, the mounting block 41 is pushed, the mounting block 41 drives the insertion block 42 to lean on the skill connecting block 21, the insertion block 42 and the fixing block 43 enter the connecting groove 22, in the entering process, the insertion block 42 pushes the limiting block 31 to shrink, the limiting block 31 pushes the spring 3 to shrink, after the insertion block 42 and the fixing block 43 completely enter the connecting groove 22, the mounting block 41 can be loosened, the spring 3 is restored and the limiting block 31 is driven to restore, the limiting block 31 pushes the insertion block 42 and the fixing block 43 downwards, the insertion block 42 drives the fixing block 43 to enter the lower end of the connecting groove 22, and the fixing block 43 is inserted into the connecting groove 22.

Specifically, the limiting block 31 is trapezoidal, so that the limiting block 31 is matched with the connecting groove 22.

Through the connecting groove 22 that sets up with inserted block 42 and fixed block 43 looks adaptation for installation piece 41 can be connected with connecting groove 22, and the stopper that sets up is fixed to inserted block 42 and fixed block 43 after the connection, makes holistic connection more firm, prevents to separate during the use.

Example two

Referring to fig. 1-3, a further improvement is made on the basis of embodiment 1:

in order to make the installation of screwdriver head 4 and connection frame 2 more stable, avoid the condition that the separation appears when using, at connection frame 2 one side joint protection shield 5 again to at protection shield 5 upper end fixed connection screw thread piece 54, screw thread 54 one side has seted up the thread groove, makes screw thread piece 54 pass through screw 6 and connection frame 2 fixed connection, thereby makes things convenient for the fixed use of protection shield 5.

Then, a groove 51 is formed on one side of the protection plate 5, an elastic member 52 is fixedly connected in the groove 51, a pushing block 53 is fixedly connected on one side of the elastic member 52 away from the groove 51, and the pushing block 53 is slidably connected with the groove 51.

The elastic member 52 is restored to keep the push block 53 always in a state of applying a force to the mounting block 41, thereby preventing the mounting block 41 from being separated.

The utility model discloses during the use, insert the installation piece 41 on the screwdriver head 4 in the connection frame 2, and make the installation piece 41 be located the one side that is close to protection shield 5, at the in-process that installation piece 41 got into, installation piece 41 can push ejector pad 53, make ejector pad 53 shrink, and push ejector pad 53 in the recess 51, be located same water flat line with the spread groove 22 on the connecting block 21 when installation piece 41, and make installation piece 41 top and 2 inner walls of connection frame meet the back, can promote installation piece 41, make installation piece 41 drive insert piece 42 and lean on skill connecting block 21, and make insert piece 42 and fixed block 43 get into in the spread groove 22, at the in-process that gets into, insert piece 42 pushes away and presses stopper 31 shrink, make stopper 31 extrusion spring 3 shrink, after insert piece 42 and fixed block 43 get into the spread groove 22 completely, can loosen installation piece 41, make spring 3 recover and drive stopper 31 and recover, make stopper 31 push away insert piece 42 and 43 downwards, make insert piece 42 drive fixed block 43 and get into fixed block 22 lower extreme, and make insertion 43 get into fixed block 22, and make simultaneously, the elasticity piece 52 can make the installation piece keep the installation separated installation of push away the installation piece 41 that the installation piece is keeping all the installation state all the time, and prevent.
