Description

Technical Field

[0001] The utility model relates to the field of manual tightening and loosening tools, in particular to a T-shaped ratchet wrench. Background Art

[0002] A wrench is a commonly used installation and removal tool. It is a hand tool that uses the principle of leverage to twist bolts, screws, nuts and other threaded fastening bolts or nuts through openings or holes. The T-type wrench is a type of wrench and is mainly used in automobile maintenance. When in use, the socket is put on the surface of the nut, and then the handle is turned to install or remove.

[0003] In daily life, T-type wrenches are used to install or remove nuts. Existing T-type wrenches generally consist of a sleeve, a driving rod and a handle, wherein the sleeve is sleeved on the surface of the nut, and then the handle is rotated to drive the connecting rod, and the connecting rod drives the sleeve to rotate, so as to install or remove the nut. However, when tightening with force, although the above method can achieve the installation effect, there is a need for further optimization in the rotation.

[0004] Due to design defects, the length of existing T-type wrenches is generally fixed. During use, it is difficult to unscrew tight bolts, screws, nuts, etc. because the lever arm is not long enough. In this case, the wrench often needs to be replaced, which is time-consuming and labor-intensive and leads to low work efficiency. Utility Model Content

[0022] like Figures 1 to 3 As shown, the utility model provides a T-shaped ratchet wrench, comprising a wrench body 1 and a wrench sleeve 2, wherein the wrench body 1 comprises:

[0023] A ratchet head 3, wherein force application handles 4 are respectively provided at both lateral ends of the ratchet head 3, and a ratchet reversing drive mechanism is provided inside the ratchet head 3;

[0024] A driving rod 6, one end of which is connected to the ratchet head 3, and the other end of which is a square head connection end 7;

[0025] The connecting rod unit 8 includes a connecting rod 9 and a sliding sleeve unit 10;

[0026] An annular groove 23 is provided on the end of the driving rod 6 close to the ratchet head 3 and the force application handle 4 to engage with the sliding sleeve unit 10 . The connecting rod 9 is sleeved on the force application handle 4 or the driving rod 6 through the sliding sleeve unit 10 and the annular groove 23 .

[0027] The design of the connecting rod unit 8 enables the wrench to have an adjustable length to meet the needs of different working scenes and increase the flexibility of use.

[0028] A handle 11 is provided at one end of the connecting rod 9, and the other end of the connecting rod 9 is a sleeve end 12. The sliding unit 10 is arranged at the sleeve end 12. An opening 13, a first slot 14 and a second slot 15 are respectively provided on the sleeve end 12. The opening 13 is arranged between the first slot 14 and the second slot 15.

[0029] The provision of the opening 13 , the first clamping slot 14 and the second clamping slot 15 facilitates the assembly and fixation of the sliding sleeve unit 10 , thereby ensuring the stability and reliability of the sliding sleeve unit 10 .

[0030] The sleeve unit 10 includes a sleeve 16, an elastic member 17, a ball 18 arranged in an opening 13, a first retaining ring 19 arranged in a first groove 14, and a second retaining ring 20 arranged in a second groove 15. A sliding slope 21 is provided in the sleeve 16, and the elastic member 17 is arranged at the lower end of the sliding slope 21. The sliding slope 21 and the ball 18 are fixed and separated by extrusion and separation of the annular groove 23.

[0031] The sleeve unit 10 can quickly and conveniently connect and disconnect the connecting rod 9 with the force application handle 4 or the driving rod 6 by cooperating with the annular groove 23, thereby improving work efficiency.

[0032] An adjustment cover 22 is disposed at the top end of the ratchet head 3 , and the driving rod 6 is connected to the bottom end of the ratchet head 3 .

[0033] The positive and negative directions of the ratchet reversing drive mechanism can be controlled by adjusting the cover 22 to meet different working requirements.

[0034] The handle 11 is provided with anti-slip patterns 24 .

[0035] The anti-slip grooves 24 on the handle 11 increase the friction between the hand and the wrench, provide a better grip, and reduce the risk of the wrench slipping during operation.

[0036] like Figures 1 to 3As shown, when in use, the sliding sleeve 16 is dragged backward to move the sliding slope 21 and disengage the connecting rod 9 from the driving rod 6. The ball 18 is forced to roll to one side of the sliding slope 21, and the connecting rod 9 is disengaged from the driving rod 6. The connecting rod 9 is then sleeved on the secondary shaft through the annular groove 23.

[0037] When the connecting rod 9 is detached from the wrench body 1, the wrench body 1 is used to tighten the nut in conjunction with the wrench socket 2. When it is necessary to tighten tighter bolts, screws, nuts, etc., the connecting rod 9 is fitted with the sliding sleeve unit 10 on the force applying handle 4, thereby lengthening the force applying handle 4, making it more labor-saving to use and improving work efficiency.

[0038] By arranging the connecting rod unit 8 on the wrench body 1, the force-applying handle 4 is lengthened and adapted to the needs of different working scenes, making it more labor-saving when used and improving work efficiency.

[0039] In the present utility model, the ratchet reversing drive mechanism and the adjusting cover 22 are existing technical means of those skilled in the art, and have been marked in the accompanying drawings, so they are not described in detail.

[0040] In the present utility model, the wrench sleeve 2 is a commonly used component by people in this field, so it is not shown in the drawings.

[0041] In the description of this specification, reference is made to the terms "one embodiment", "some embodiments", "examples", "specific examples", etc.
