[0026] The following detailed description provides further details on specific implementation methods.

[0027] like Figures 1 to 4 As shown, this application provides an assembled F-type wrench, including a wrench body 1, a fixed stop block 2, and a sliding stop block 3. The fixed stop block 2 is installed at one end of the wrench body 1, and the sliding stop block 3 is slidably installed on the side of the wrench body 1. An extension handle 4 is installed at the other end of the wrench body 1. Multiple connecting holes 5 are provided on the sides of both the wrench body 1 and the extension handle 4. A fixing rod 6 is installed at one end of each connecting hole 5, and a threaded sleeve 7 is installed at one end of the fixing rod 6. The extension handle 4 is connected to the wrench body 1 through the fixing rod 6.

[0028] An anti-slip sleeve 12 is installed on the side of the extension handle 4. The anti-slip sleeve 12 has a connection hole 5 that is the same as that of the extension handle 4. A threaded rod 13 is installed at one end of the fixing rod 6. The threaded sleeve 7 is threadedly connected to the side of the threaded rod 13. The extension handle 4 is slidably sleeved on the side of the wrench body 1. The position of the extension handle 4 on the wrench body 1 is adjusted through the connection hole 5.

[0029] When the length of the wrench body 1 is insufficient, an extension handle 4 can be fitted onto the side of the wrench body 1. The connecting hole 5 on the extension handle 4 is aligned with the connecting hole 5 on the wrench body 1 to lengthen the wrench body 1. After the connecting holes 5 are aligned, the fixing rod 6 is inserted into the connecting hole 5. A threaded sleeve 7 is rotated and installed at one end of the fixing rod 6, the threaded rod 13, so that the side of the threaded sleeve 7 abuts against the anti-slip sleeve 12, thereby fixing the position of the extension handle 4 on the wrench body 1. By adjusting the position of the connecting hole 5 on the extension handle 4, the required length can be adjusted. The operator can use the wrench body 1 without replacing it, saving effort.

[0030] Preferably, a plurality of friction grooves 11 are provided at one end of both the fixed abutment 2 and the sliding abutment 3, and the friction grooves 11 of the fixed abutment 2 and the sliding abutment 3 are arranged opposite to each other.

[0031] Preferably, the side of the wrench body 1 is provided with a plurality of anti-slip grooves 14 for anti-slip purposes, and the anti-slip effect is increased by gripping the anti-slip grooves 14 on the side of the wrench body 1.

[0033] The working principle of the assembled F wrench provided by the application is as follows: when the wrench body 1 is needed to be used, the position of the lever is adjusted by the sliding block 3 on the wrench body 1, the worm 9 is rotated through the opening of the movable slot 8, the engagement between the worm 9 and the tooth block 10 drives the sliding block 3 to move as a whole, and then the distance between the fixed block 2 and the sliding block 3 is adjusted, so that the wrench body 1 is better adapted to different working environments. The anti-skid groove 14 on the side of the wrench body 1 increases the anti-skid effect, when the length of the wrench body 1 is not enough, the extension handle 4 can be sleeved on the side of the wrench body 1, the connecting holes 5 on the extension handle 4 are installed in the corresponding connecting holes 5 on the wrench body 1, the wrench body 1 is lengthened, when the connecting holes 5 are aligned, the fixed rod 6 is inserted into the connecting holes 5, the threaded sleeve 7 is rotatably installed at the threaded rod 13 on one end of the fixed rod 6, the side of the threaded sleeve 7 is abutted against the anti-skid sleeve 12, and then the position of the extension handle 4 on the wrench body 1 is fixed, the length to be lengthened is adjusted by adjusting the position of the connecting holes 5 on the extension handle 4, and the operator can use the wrench body 1 without replacing it. When it is needed to be carried, the threaded sleeve 7 on the side of the fixed rod 6 is screwed out, the fixed rod 6 is disassembled, the extension handle 4 is slid out, the position of the worm 9 is continuously rotated, one end of the sliding block 3 is lowered, when the engagement between the worm 9 and the tooth block 10 is separated, the sliding block 3 can be slid out from the side of the wrench body 1, the disassembly of the wrench body 1 is completed, the user can carry the wrench body 1, and the adaptability of the wrench body 1 is improved.

[0034] The above merely describes the specific embodiments of the application, but the protection scope of the application is not limited to this, any changes or replacements within the technical range disclosed by the application can be easily thought by those skilled in the art, and should be covered in the protection scope of the application.
