DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in FIGS. 1 to 5 , the utility model provides an electric screwdriver head assembly, comprising:

A handle seat 1, the top of which is detachably connected to an electric screwdriver body 2, and a rotating shaft 3 is provided at the left end of the electric screwdriver body 2;

The limiting mechanism is arranged on the left side of the electric screwdriver body 2;

A disassembly mechanism, which is arranged below the electric screwdriver body 2;

Among them, the limiting mechanism includes a sleeve 4, which is rotatably connected to the left end of the electric screwdriver body 2, and the outer surface of the rotating shaft 3 is movably sleeved with an electric screwdriver head 5. A top groove 6 is opened on the right side of the top of the electric screwdriver head 5. The bottom of the inner wall of the top groove 6 is fixedly connected with a first spring 7, and the other end of the first spring 7 is fixedly connected with a round block 8. The top of the round block 8 is movably connected with a pressure block 9, and the top of the pressure block 9 extends to the top of the sleeve 4. The top of the round block 8 moves downward to the inside of the top groove 6 to release the limiting effect on the electric screwdriver head 5.

By setting the first spring 7 to a compressed state, the round block 8 will tend to move upward due to the elastic force of the first spring 7. By pressing the pressing block 9 downward, the round block 8 can be pushed to move downward and squeeze the first spring 7. When the top of the round block 8 moves to the inside of the top groove 6, the limiting effect on the electric screwdriver head 5 is released.

Among them, there are:

The disassembly mechanism is composed of a fixing block 10, a square block 11, a latch 12 and a pull handle 13;

The fixing block 10 is fixedly installed on the right side of the bottom of the electric screwdriver body 2 and the bottom end of the fixing block 10 passes through the handle base 1, the block 11 is fixedly installed on the right side of the top of the inner surface of the handle base 1, the pin 12 is movably installed on the inner wall of the block 11, the left end of the pin 12 extends to the inside of the fixed block 10, and the handle 13 is fixedly connected to the right end of the pin 12. The left end of the pin 12 can be pulled out from the inside of the fixed block 10 to release the fixing effect on the electric screwdriver body 2.

By pulling the handle 13 to the right, the latch 12 can be driven to move to the right. When the left end of the latch 12 is pulled out from the interior of the fixing block 10, the handle seat 1 can be disassembled and separated from the electric screwdriver body 2.

The outer surface of the latch pin 12 is movably sleeved with a second spring 14 , and two ends of the second spring 14 are respectively fixedly connected to the outer surfaces of the block 11 and the handle 13 .

By setting the second spring 14 to a stretched state, the latch 12 will tend to move leftward due to the elastic restoring effect of the second spring 14 , so that the left end of the latch 12 can be kept inside the fixing block 10 .

Among them, a movable block 15 is movably installed on the inner wall of the handle seat 1, a vertical plate 16 is fixedly connected to the right side of the top of the movable block 15, and a button 17 is movably installed in the middle of the bottom end of the electric screwdriver body 2.

By pressing the movable block 15 to the right, the vertical plate 16 can press the button 17, so that the electric screwdriver body 2 can be operated.

The right end of the movable block 15 is fixedly connected to a return spring 18 , and the right end of the return spring 18 is fixedly connected to the inner wall of the handle seat 1 .

By setting the return spring 18 to a normal state, the return spring 18 has an elastic force, so that the movable block 15 can return to its original position when the staff releases the pressure on the movable block 15 .

A sheath 19 is fixedly sleeved on the bottom of the outer surface of the handle seat 1, and the sheath 19 is made of rubber.

The soft nature of rubber can make the worker feel more comfortable when holding the handle seat 1 through the sheath 19 .

The bottom surface of the pressing block 9 has the same size as the top surface of the round block 8, and the outer surface of the pressing block 9 is smooth.

The smooth outer surface of the pressing block 9 can make the pressing block 9 move more smoothly when moving up and down.

The working principle and use process of this utility model:

During use, the staff can press the movable block 15 so that the vertical plate 16 squeezes the button 17 to start the electric screwdriver body 2 to load and unload the bolt. When it is necessary to use it in a smaller space and the handle base 1 and the electric screwdriver body 2 need to be disassembled and separated, the staff can pull the handle 13 to the right, driving the pin 12 to move to the right and stretch the second spring 14. When the left end of the pin 12 is pulled out from the inside of the fixed block 10, the limiting effect on the fixed block 10 is released, and the staff can disassemble and separate the electric screwdriver body 2 from the handle base 1, so that the electric screwdriver body 2 can be held alone for use, thereby improving the applicability of the device.

When the electric screwdriver head 5 needs to be replaced, the staff can first press the pressure block 9 downward, thereby pushing the round block 8 to move downward and squeeze the first spring 7. When the top of the round block 8 moves to the inside of the top groove 6, the limiting effect on the electric screwdriver head 5 is released, and the staff can pull out the electric screwdriver head 5 for disassembly and replacement, thereby finally achieving the effect of facilitating the disassembly and replacement of the electric screwdriver head 5. There is no problem of affecting the replacement efficiency due to the tight cover being difficult to unscrew, thereby facilitating the staff to replace the electric screwdriver head 5 and improving work efficiency.
