The utility model discloses a power-assisted screwdriver, which comprises a handle and a bolt cutter head. The handle includes a power-assisted handle and a fixed handle for fixing the screwdriver head. One end of the power-assisted handle and the fixed handle is provided with an outwardly protruding Out of the slider, the other is provided with an outwardly extending sliding tongue, the sliding tongue is provided with a chute, and the outer end of the slider is fixed in the chute by a fixing pin and is slidably connected with the sliding tongue. The ends of the booster handle and the fixed handle are provided with cavities recessed inward for placing a sliding tongue or a slider on the other handle. The new type of power-assisted screwdriver is specially designed to solve the problem that the ordinary screwdriver cannot screw the screw due to the small screwing force. The surface of this screwdriver is no different from that of the ordinary screwdriver. It can reach 5 to 10 times that of ordinary screwdrivers, allowing users to generate great screwing force with very little force.

Description

A power screwdriver

technical field

The utility model relates to a novel power-assisted screwdriver.

Background technique

In our actual work, we often encounter screws that cannot be screwed due to corrosion and other reasons. The common method is to add bolt looseners, but this method is not a panacea. Sometimes the bolts still cannot be screwed. In addition to the long waiting time, you may still need to use tools such as adjustable wrenches to assist, which makes simple work extremely complicated. If you do not carry a wrench, you may not be able to continue waiting.

Utility model content

The technical problem to be solved by the utility model is to realize a tool that can unscrew bolts that cannot be screwed due to corrosion and other reasons in a short time.

In order to achieve the above object, the technical solution adopted in the utility model is: a power-assisted screwdriver, including a handle and a bolt cutter head, the handle includes a power-assisted handle and a fixed handle for fixing the screwdriver head, and the power-assisted handle and the fixed handle are One end of one end is provided with a sliding block protruding outward, and the other is provided with a sliding tongue extending outward. The sliding tongue is provided with a sliding groove, and the outer end of the sliding block is fixed in the sliding groove by a fixing pin. Slidingly connected with the sliding tongue, the ends of the booster handle and the fixed handle are provided with an inwardly recessed cavity for placing a sliding tongue or a slider on the other handle.

The connecting part of the booster handle and the fixed handle is provided with external threads, and is connected and fixed through a fixing sleeve with internal threads.

The slider is two sheet structures, and clamps the sliding tongue.

The new type of power-assisted screwdriver is specially designed to solve the problem that the ordinary screwdriver cannot screw the screw due to the small screwing force. The surface of this screwdriver is no different from that of the ordinary screwdriver. It can reach 5 to 10 times that of ordinary screwdrivers, allowing users to generate great screwing force with very little force.

The marks in the above figures are: 1. screwdriver head; 2. handle; 3. power-assisted handle; 4. fixed handle; 5. fixed sleeve; 6. slider; 7. sliding tongue; groove.

Detailed ways

Referring to Figures 1-5, it can be seen that the booster screwdriver includes a handle 2 and a bolt bit 1, wherein the handle 2 is composed of a booster handle 3 and a fixed handle 4 that fixes the screwdriver bit 1, and one end of the booster handle 3 and the fixed handle 4 is provided with a The slider 6 protrudes outwards, and the other is provided with an outwardly extending sliding tongue 7. Below, the slider 6 is provided on the booster handle 3, and the sliding tongue 7 is provided on the fixed handle 4. For example, the above sliding tongue 7 There is a chute 9 on the top, and the outer end of the slider 6 is fixed in the chute 9 through the fixed pin 8 and is slidably connected with the sliding tongue 7, so that the booster handle 3 and the fixed handle 4 are in a sliding connection relationship, and the booster handle 3 can pass through the fixed pin. 8 rotates in the chute 9, in order to facilitate the carrying and normal use of the screwdriver, one end of the slider 6 on the booster handle 3 is provided with a cavity for placing the sliding tongue 7, and the corresponding sliding tongue is provided on the fixed handle 4 One end of 7 is provided with a cavity for placing the slider 6, so that when the booster handle 3 and the fixed handle 4 are folded together, the slider 6 and the sliding tongue 7 all slide into the cavity, and then at the connecting part of the booster handle 3 and the fixed handle 4 External thread is provided and connected and fixed by the fixed sleeve 5 with internal thread, then the shape and function of the screwdriver can be restored to the common screwdriver.

When the screwdriver is using the booster function, you only need to unscrew the fixing sleeve 5, the booster handle 3 and the fixed handle 4 are stretched away from each other, and then rotate the booster handle 3 so that the booster handle 3 and the fixed handle 4 form an angle of 90 degrees, then you can use The principle of leverage expands the force of screwing the bolt. In order to improve the reliability of use, the slider 6 is recommended to be designed as two sheet structures, and to clamp the sliding tongue 7, so that when the power-assisted function of the screwdriver is used, the torque between the fixing pin 8 and the sliding groove 9 can be reduced, and the The torsion force is evenly distributed to the contact surface between the slider 6 and the sliding tongue 7, which can effectively improve the reliability and service life of the power-assisted screwdriver.

The utility model has been exemplarily described above in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above-mentioned methods, as long as various insubstantial improvements are made by adopting the method concept and technical solutions of the utility model, or Directly applying the ideas and technical solutions of the utility model to other occasions without improvement is within the protection scope of the utility model.
