Description

Automatic screwdriver

The present invention relates to a screwdriver, and more particularly to an automatic screwdriver.

Nowadays, in the workplace or in the home life, most of the machines and equipment are almost fixed or installed with screws. For the maintenance personnel or housewives, the traditional screwdrivers often need to be complicated many times. The rotation is effective to fix the screw or remove the screw.

Of course, there are also electric screwdrivers to assist the user in quickly fixing or removing the screws. For example, the maintenance personnel of the locomotive maintenance line often need to fix or remove the screws a lot during the maintenance process. , often with the help of electric screwdrivers to improve work efficiency.

However, the electric screwdriver is convenient, but it must rely on the power supply to provide a mechanism for the quick rotation of the screwdriver, so that the action of quickly fixing or removing the screw can be achieved, once the user has no power available for the week, or When an emergency occurs in an outdoor environment, it is often impossible to use a screwdriver. Therefore, the electric screwdriver is convenient, and it is easily limited by the use situation or environmental restrictions, which causes inconvenience.

Therefore, an object of the present invention is to provide an automatic screwdriver comprising: a body, a hollow cylindrical body and having an opening; a switching unit disposed in the opening and having a cut a locking portion and a detaching mode ball portion; a sliding limiting unit disposed in the body, comprising a first sliding rail and a second sliding rail; a screw sleeve unit, and the sliding limit The bit unit is connected and has a screw head; when the switch unit is switched to the locking mode, the switch unit controls the ball to slide on the first slide rail of the sliding limit unit, and interlocks the screw head Rotate in a first direction.

Therefore, the utility model has the advantages that the sliding rails of the two different directions are arranged on the sliding limiting unit, and when the spherical portion slides on different sliding rails, the screw head can be rotated in different directions for the user. In order to lock or remove the screw, it is only necessary to align the screw head with the screw to be actuated, and then press the body forward to automatically produce the effect of rotating the screw head. Therefore, compared with It is undoubtedly a lot more convenient for the traditional method of multiple rotations to be used. In addition, since the present invention utilizes a linear force when the body is pressed forward, the combination of the spherical portion and the different slide rails automatically converts into a rotational force. Therefore, no additional energy (for example, electric energy) is needed, and the rotating force can be automatically generated. There is no restriction on the use situation, as long as the user has sufficient strength to complete the forward pressing action, it can be in any environment. Used in it.

1 is a cross-sectional view of a preferred embodiment of the present invention; FIG. 2 is a side cross-sectional view of the preferred embodiment; FIG. 3 is a top cross-sectional view of the preferred embodiment; 3 is a perspective view of the embodiment; and FIG. 5 is a schematic diagram of the actuation relationship between the switch unit and the sliding limit unit of the preferred embodiment.

The details of the related patents and the technical contents of the present invention will be apparent from the following detailed description of a preferred embodiment of the drawings.

Referring to FIG. 1 to FIG. 4, a preferred embodiment of the present invention comprises: a body 3, a switch unit 4, a sliding limit unit 5, and a screw sleeve unit 6.

The body 3 is a hollow cylinder having an opening 30 on its surface and an elastic member 31 therein. The elastic member 31 is removably placed inside the hollow interior of the body 3.

The switch unit 4 is disposed on the opening 30 and has a handle portion 41, a connecting portion 42 and a spherical portion 43. The handle portion 41 is coupled to the connecting portion 42 , and a user can control the connecting portion 42 to switch between a locking mode and a unloading mode via the handle portion 41 , and the connecting portion 42 and the ball are The portion 43 is engaged, that is, one end of the connecting portion 42 in contact with the spherical portion 43 is arcuate, so that the connecting portion 42 and the spherical portion are selectively engaged.

The sliding limiting unit 5 is disposed inside the body 3 and has a set of first sliding rails 51 and a set of second sliding rails 52. When the handle 41 controls the connecting portion 42 to switch to the locking mode The connecting portion 42 is engaged with the spherical portion 43 and moved to the starting point of the first sliding rail 51, and when the spherical portion 43 starts to slide on the first sliding rail 51, then the The ball portion 43 will be disengaged from the connecting portion 42 or, when the handle portion 41 controls the connecting portion 42 to switch to the unloading mode, the connecting portion 42 is engaged with the ball portion 43 and moved to the first portion The starting point of the two slide rails 52, and when the spherical portion 43 starts to slide on the second slide rail 52, the spherical portion 43 will be disengaged from the connecting portion 42.

The screw sleeve unit 6 includes a sleeve member 61 and a screw head 62. The sleeve member 61 is connected to the sliding limit unit 5, and when the sliding limit unit 5 is disposed inside the body 3, the sleeve member 61 can be The card is disposed on the upper edge of the body 3, and the screw head 62 is engaged with the sleeve member 61.

Referring to FIG. 5, when the user sets the starting point of the first sliding rail 51 of the ball portion 43 via the handle portion 41, the user holds the body 3 and presses it forward, one of the sleeve members 61. The portion will be displaced into the body 3, and the spherical portion 43 will slide along the first sliding rail 51 due to the relative displacement, thereby driving the screw head 62 to rotate in a first direction. Screw the corresponding screw.

Referring to FIG. 1 and FIG. 4, when the user sets the starting point of the second sliding rail 52 of the spherical portion 43 via the handle portion 41, the sleeve is pressed by the user when the user holds the body 3 and is pressed forward. A portion of the member 61 will be displaced into the body 3, and the ball portion 43 will slide along the second rail 52 due to the relative displacement, thereby driving the screw head 62 to rotate in a second direction. To remove the corresponding screw.

Preferably, the first direction is a clockwise direction and the second direction is a counterclockwise direction.

Preferably, the elastic member 31 is configured to provide a restoring force of the sliding limiting unit 5, so that when the user releases the force of pressing the body 3, the sliding limiting unit 5 can automatically return to the initial position.

The utility model utilizes the sliding rails of the sliding limiting unit to have two different directions, and when the spherical portion slides on different sliding rails, the screw head can be rotated in different directions, for the user to lock When tightening or removing the screw, just align the screw head with the screw to be actuated, and then squeeze the body forward to automatically produce the effect of rotating the screw head. Therefore, it is necessary to select multiple times compared with the traditional one. It is undoubtedly much more convenient in terms of the driving method. In addition, since the present invention utilizes the linear force when the body is pressed forward, the combination of the spherical portion and the different sliding rails automatically converts into a rotating force, so that no extra is needed. The energy (for example: electric energy) can automatically generate the rotating force. There is no restriction on the use situation, as long as the user The purpose of the present invention can be attained by having sufficient force to perform the forward squeezing action, which can be used in any environment.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
