[0001] This utility model relates to the field of bit technology, and in particular to a power tool bit. Background Technology
[0002] Screwdriver bits, as the core working component of power tools, are widely used in mechanical assembly, electronic equipment repair, home renovation, and other fields. Their core function is to transmit torque through engagement with screw heads. With the increasing precision requirements of industrial manufacturing and the enhancement of power tool performance, the market has placed higher demands on the wear resistance, torsional strength, and compatibility stability of screwdriver bits.
[0003] After prolonged use, the end of the existing bit that contacts the workpiece may experience excessive wear. This wear may cause the end to slip and shift away from the workpiece. At the same time, the overall structural strength and torsional resistance of the bit need to be improved. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a power tool bit that overcomes the deficiencies of the prior art. It aims to solve the problem that the end of the existing bit that contacts the part may wear excessively after long-term use, which may cause the end to slip and shift in contact with the part. At the same time, the overall structural strength and torsional resistance of the bit need to be strengthened.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a power tool bit, including a head, a connecting part at one end of the head, a limiting part at the other end of the connecting part, multiple sets of limiting parts on the outside of the limiting part, a driving part at the bottom of the limiting part, four sets of driving grooves on the outside of the driving part, and a tail end at the bottom of the driving part, wherein the cross-section of the head and the connecting part are both hexagonal.
[0006] By adopting the above technical solution and by setting the head, when in use, one end of the bit is placed inside the power tool. The clamping mechanism inside the power tool can directly enter the drive groove. The drive unit makes the bit rotate. When the rotation angle changes, it can abut against the two sides of the drive groove, effectively improving the overall strength. The external limiting part can ensure the limiting of the bit and fix it to prevent it from falling out.

[0010] By adopting the above technical solution and setting anti-slip teeth, the stability of the connection can be further improved when in contact with other parts, preventing the phenomenon of displacement.
[0011] As a preferred embodiment of this utility model, the outer side of the fixing sleeve is provided with multiple sets of reinforcing plates, and all sets of reinforcing plates are fixedly connected to the outer wall of the head.
[0012] By adopting the above technical solution and setting up reinforcing plates, the structural strength and connection tightness can be further improved during use, thereby enhancing the practicality of the device.
[0013] As a preferred embodiment of this invention, chamfers are provided on both sides of the multiple sets of drive slots.
[0014] By adopting the above technical solution and setting chamfers on both sides of the drive groove, the concentration of torque on the outside of the drive part can be effectively reduced, making the force distribution more uniform and effectively improving the load-bearing effect.
[0015] As a preferred embodiment of this utility model, a magnetic suction module is provided at the top of the head.
[0016] By adopting the above technical solution, the magnetic module can be made more convenient to use, enabling magnetic attraction of mechanical parts, making installation and disassembly easier, and improving the practicality of the device.
[0017] As a preferred embodiment of this invention, both the head and the connecting portion are provided with a wear-resistant coating.
[0018] By adopting the above technical solution and setting a wear-resistant coating, damage to the bit's exterior from external parts can be reduced during use, thus improving the device's practicality.
[0019] The beneficial effects of this utility model are:
[0020] 1. By setting the head, when in use, one end of the bit is placed inside the power tool. The clamping mechanism inside the power tool can directly enter the drive groove. The drive unit makes the bit rotate. When the rotation angle changes, it can abut against the two sides of the drive groove, effectively improving the overall strength.

The head 1 and the connecting part 2 are both provided with wear-resistant coatings. By providing wear-resistant coatings, the damage of external parts to the outside of the bit can be reduced during use, improving the practicality of the device.
[0032] Working principle: By setting the head 1, when in use, one end of the bit is placed inside the power tool. The clamping mechanism inside the power tool can directly enter the drive groove 401. The drive part 4 makes the bit rotate. When the rotation angle changes, it can abut against the two sides of the drive groove 401, effectively improving the overall strength. The limit part 301 on the outside can ensure the limit of the bit and fix it to prevent it from falling out. By setting the fixing sleeve 201, the connection between the head 1 and the connecting part 2 can be made tighter, and the overall connection strength between the head 1 and the connecting part 2 can be further improved. In the long-term use, the stability is further improved and the practicality of the device is enhanced.

By setting reinforcing plate 202, structural strength and connection tightness can be further improved during use, and the practicality of the device can be enhanced.
[0034] Meanwhile, by setting chamfers on both sides of the drive groove 401, the concentration of torque on the outside of the drive part 4 can be effectively reduced, making the force more uniform and effectively improving the load-bearing effect.
[0035] In addition, the magnetic module makes it more convenient to use, as it can magnetically attract mechanical parts, making installation and disassembly easier and improving the practicality of the device. The wear-resistant coating reduces damage to the bit from external parts during use, further enhancing the device's usability.
