Description

Technical Field

[0001] The present application relates to the technical field of electric screwdrivers, and in particular to a protective electric screwdriver. Background Art

[0002] Electric screwdrivers are convenient and efficient electric tools suitable for tasks that require a large number of screws to be tightened or removed, such as assembling furniture, installing fixtures, etc. Common electric screwdrivers are divided into two types: gun-type and pen-type. Gun-type screwdrivers are larger and are usually stored in tool boxes after use; pen-type screwdrivers require less storage space and are relatively safer, so they are often placed at hand.

[0003] However, there is a risk of a screwdriver being dropped if it is placed carelessly. If the screwdriver is accidentally dropped, the protruding screwdriver head will be easily damaged after colliding with the ground, and the entire screwdriver may even be scrapped. In addition, the screwdriver head and button of the pen-type screwdriver are exposed. If the button is accidentally pressed, the screwdriver head will rotate, which may cause property damage or personal injury. Therefore, there is still room for improvement in existing pen-type electric screwdrivers. Utility Model Content

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] Example 1

[0026] Embodiment 1 of the present application discloses a protective electric screwdriver. Figure 1 and Figure 2 The protective electric screwdriver includes a rod 1 and a screwdriver head 2 installed at one end of the rod 1. The end of the rod 1 where the screwdriver head 2 is installed is the head end of the rod 1, and the other end of the rod 1 is the tail end of the rod 1. The installation method, internal structure and working principle of the rod 1 and the screwdriver head 2 are the same as those of the existing pen-type electric screwdriver, and will not be repeated here. The outer periphery of the rod 1 is provided with an anti-slip cover 3, and the anti-slip cover 3 is shown as a silicone material.

[0027] The head end of the rod 1 is detachably connected with a protective cover 4 for covering the screwdriver head 2. When the protective cover 4 covers the screwdriver head 2, an escape gap 41 is left between the top of the inner part of the protective cover 4 and the screwdriver head 2, thereby preventing the screwdriver head from being bent or broken due to the protective cover 4 always squeezing the screwdriver head 2. The rod 1 is also connected with a storage piece, and when the protective cover 4 is not needed, the storage piece can be used to fix the protective cover 4 on the rod 1.

[0028] In Example 1 of the present application, the protective cover 4 is made of magnetic material. A first magnetic ring 5 is bonded to the head end of the rod 1, and the first magnetic ring 5 is fixed to the protective cover 4 by magnetic attraction. The storage piece is arranged at the tail end of the rod 1, and the storage piece is a second magnetic ring. The tail end of the rod 1 is provided with an embedded ring groove 11 for the storage piece to be embedded. The groove depth of the embedded ring groove 11 is greater than the height of the storage piece, that is, when the protective cover 4 is magnetically fixed to the rear end of the rod 1, the bottom of the protective cover 4 is embedded in the embedded ring groove 11, and the groove wall of the embedded ring groove 11 can reduce the probability of the protective cover 4 being accidentally knocked off.

[0029] The implementation principle of a protective electric screwdriver in embodiment 1 of the present application is: when the electric screwdriver needs to be used, remove the protective cover 4 and magnetically attach it to the tail end of the rod 1; when use is finished, magnetically close the protective cover 4 again to protect the screwdriver head 2.
