Abstract

The tail telescopic structure of the digital display torque wrench comprises a tail end, an inserting groove is formed in the tail end, an inner groove is formed in an outlet of the inserting groove, a rectangular-ambulatory-plane inserting block is arranged in the inner groove in an inserting mode, a sliding rod is arranged in the inserting groove in a sliding mode, and the outer wall of the sliding rod abuts against the inner wall of the inserting block. A penetrating hole is formed in the outer side of the tail end, and a screw spirally fixed to the inserting block penetrates through the penetrating hole. Compared with the prior art, the utility model has the following advantages and effects: when the outer end position of the plug-in block is sunken after the plug-in block is used for a certain time, the screw on the plug-in block can be taken out, and the plug-in block is rotated by an angle after being withdrawn, so that the other extension strip penetrates into the extension groove and then is reassembled and fixed. Therefore, compared with a traditional telescopic structure, the service life can be effectively prolonged.

Description

Technical Field

[0001] The utility model relates to a digital display torque wrench, in particular to a tail telescopic structure of the digital display torque wrench. Background Art

[0002] As the name implies, a digital display torque wrench is a torque wrench with a digital display, which uses a digital display screen or an LED light to prompt the user, and the torque setting can also be completed through buttons and the digital display screen, which is more convenient and easier to operate than a non-digital display torque wrench.

[0003] The digital display torque wrench in the prior art usually includes a handle, and the function of convenient storage needs to be considered in a specific environment. By setting a telescopic rod at the tail of the handle, the overall length can be effectively increased, which is convenient for the staff to press, reduces the work burden, and ensures the required force.

[0004] However, due to the relative movement between the telescopic rod and the tail of the torque wrench during pressing, it is easy to cause extrusion at the opening of the end of the telescopic rod, resulting in depression at the opening of the wrench tail, relative looseness between the telescopic rod and the wrench tail, and affecting subsequent use. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tail telescopic structure of a digital display torque wrench.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a tail telescopic structure of a digital display torque wrench, including a tail end, a slot is arranged inside the tail end, an inner groove is arranged at the outlet of the slot, a zigzag-shaped plug-in block is inserted in the inner groove, a sliding rod is slidably arranged in the slot, and the outer wall of the sliding rod abuts against the inner wall of the plug-in block; a through hole is arranged on the outer side of the tail end, and a screw spirally fixed to the plug-in block is inserted through the through hole.

[0007] It is further set that: extension strips are arranged on both sides of the plug-in block, and extension grooves are arranged on the inner groove, and the extension strips are inserted into the extension grooves.

[0008] It is further set that: a through slot is arranged at the bottom surface of the extension groove, and an extension rod inserted into the through slot is arranged at the end of the extension strip.

[0009] It is further set that: the through slot and the extension rod are of mutually adapted conical shapes.

[0010] It is further set that: the cross section of the extension strip is semi-circular.

[0011] In summary, the utility model has the following beneficial effects: When it is found that the outer end of the insertion block is sunken after a certain period of use, the screw on the insertion block can be removed, the insertion block can be withdrawn and rotated by an angle, so that the other extension strips are inserted into the extension grooves, and then reinstalled and fixed. Therefore, compared with the traditional telescopic structure, the service life can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the tail telescopic structure of the digital display torque wrench.

[0013] In the figure: 1, the tail end; 2, the slot; 3, the inner groove; 4, the insertion block; 5, the sliding rod; 6, the through hole; 7, the screw; 8, the extension strip; 9, the extension groove; 10, the through slot; 11, the extension rod. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The following further details the present utility model with reference to the accompanying drawings.

[0015] The tail telescopic structure of the digital display torque wrench includes the tail end 1 of the handle. The tail end 1 is provided with a slot 2, and the slot 2 is cylindrical.

[0016] An inner groove 3 is provided at the outlet of the slot 2, and the inner groove 3 is circular. A plurality of extension grooves 9 with a semicircular cross-section are provided on the inner wall of the slot 2, and a circular loop-shaped insertion block 4 is provided on the inner groove 3. A sliding rod 5 is slidably arranged in the slot 2, and the outer wall of the sliding rod 5 abuts against the inner wall of the insertion block 4.

[0017] A plurality of extension strips 8 with a semicircular cross-section are provided inside the insertion block 4, and the extension strips 8 correspond to the extension grooves 9 one by one.

[0018] A conical extension rod 11 is further provided at the end of the extension strip 8, and a conical through slot 10 corresponding to the extension rod 11 is provided on the bottom surface of the slot 2. The extension rod 11 penetrates into the through slot 10 to fix the extension strip 8. At the same time, the conical through slot 10 can also play a guiding role for the extension rod 11, facilitating the penetration of the extension rod 11 into the through slot 10 to realize the penetration of the insertion block 4.

[0019] A through hole 6 is provided on the outer side of the tail end 1, and a screw 7 screwed and fixed to the insertion block 4 is inserted into the through hole 6. The insertion block 4 can be fixed by the screw 7.

[0020] When it is found that the outer end of the insertion block 4 is sunken after a certain period of use, the screw 7 on the insertion block 4 can be removed, the insertion block 4 can be withdrawn and rotated by an angle, so that the other extension strips 8 are inserted into the extension grooves 9, and then reinstalled and fixed. Therefore, compared with the traditional telescopic structure, the service life can be effectively improved.

[0021] This specific embodiment is only an interpretation of the present utility model, and it does not limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.
