In addition, in the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

Example 1

The present invention provides an improved orthopedic electric drill, as shown in Figures 1-4, comprising an electric drill main body 1, a threaded joint 13 is provided on the rear side of the electric drill main body 1, and a connecting assembly 2 is installed on the threaded joint 13, and the connecting assembly 2 includes The connecting head 20 and the connecting rod 21 arranged on one side of the connecting head 20, the end of the connecting rod 21 is equipped with a drill bit 3, the bottom of the electric drill main body 1 is provided with a handle 4, and the right side wall of the handle 4 is provided with an anti-skid pattern 40, The rear side wall of the handle 4 is provided with several finger grooves 41, the bottom of the handle 4 is provided with a power supply slot 42, and the two side walls of the power supply slot 42 are respectively provided with a plug-in slot 420 and a buckle slot 421. There is a flip cover 5, and a plugboard 50 and a buckle 51 are installed on the two side walls of the flip cover 5.

In this embodiment, the main body 1 of the electric drill and the handle 4 are integrally formed to ensure the stability of the connection between the main body 1 of the electric drill and the handle 4 , and to facilitate subsequent holding of the electric drill.

Further, the threaded joint 13 is threadedly connected with the connecting head 20. When the connecting head 20 is rotated, the thread on the inner wall of the connecting head 20 can be matched with the thread on the outer wall of the threaded joint 13 to generate a force, so that the threaded joint 13 can be connected along the The inner wall of the head 20 moves to separate the connecting head 20 from the threaded joint 13 to disassemble the drill bit 3, or fix the connecting head 20 to the threaded joint 13 to install the drill bit 3, which is convenient for dismounting or installing the drill bit 3.

In the actual process, in order to facilitate battery replacement, the diameter of the power supply slot 42 is adapted to the diameter of the flip cover 5, and the buckle 51 is engaged with the buckle slot 421. When the power supply slot 42 is closed, the plug-in plate 50 can be inserted into the slot. inside the board slot 420, and buckle 51 is snapped into the buckle slot 421 to realize fixing the flip cover 5 to the inside of the power supply slot 42 to achieve the purpose of closing the power slot 42, and the buckle 51 is taken out of the inside of the buckle slot 421, and the plate 50 is inserted into the inside of the slot 420 to open the power slot 42.

It is worth noting that the side wall of the buckle 51 is in the shape of a "U". The partial deformation of the shape of "" will react against the inner wall of the buckle groove 421 under the condition that the force generated by the deformation recovery increases the frictional force between the buckle 51 and the inner wall of the buckle groove 421 to ensure that the buckle 51 is snapped into the buckle groove 421 internal stability.

In the specific implementation process, in order to facilitate the grip of the handle 4, the friction force between the handle 4 and the fingers is increased through the anti-skid pattern 40, so as to avoid the problem that the handle 4 is smooth and difficult to hold, and by inserting the fingers into the corresponding finger grooves 41 interior, to improve the comfort of holding the handle 4.
