Double-head wrench capable of measuring locking clearance and being used for chiseling

Abstract

The invention discloses a double-head wrench capable of measuring a locking clearance and can be used for chiselling. The double-head wrench comprises an middle handle, a wrench head I arranged at thefront end of the middle handle and a wrench head II arranged at the rear end of the middle handle, a wrench opening of the groove body structure is formed in the front end of the wrench head I, a groove bottom of the wrench opening is provided with two bent grooves with groove structures towards the rear end of the wrench head I, and the main body of the middle handle is of a plate-shaped structure; and a clearance measuring piece set is arranged in a storage groove I at the side of the middle handle, the assembling clearance of the plate type part after locking can be detected through measuring pieces on the clearance measuring piece set, and then whether the fit between the two parts is in place or not is determined, so that the wrench can clamp the plate type part more firmly; a chiselling block is arranged in a storage groove II at the rear end of the middle handle in a matched mode, and the chisel block can be taken out and can be used as a chisel, and meanwhile, the chisel blockcan be inserted into a fixing groove I of the wrench head II, so that the wrench head II forms a sharp pick shape, and the whole wrench has breaking and breakdown capabilities.

Description

technical field [0001] The invention relates to the technical field of hardware, in particular to a double-ended wrench capable of measuring locking gaps and chisling. Background technique [0002] The double-ended wrench is a commonly used hardware tool. It can disassemble or assemble the screw and the nut by rotating to generate a rotational torque. The double-ended wrench is easy to make and easy to use, so it is popular, but it is still used in actual There are the following disadvantages: [0003] 1. When the double-ended wrench locks two board parts, it is impossible to estimate the fitting gap between the two boards after locking, and thus cannot judge the effect of locking, resulting in frequent fitting gaps If it is too large, the locking is not firm; [0004] 2. When a double-ended wrench encounters an overstretched screw, it needs to use a tool such as a chisel to loosen the screw first, and then use a wrench for further disassembly. The chisel is relatively sma...

AI Technical Summary

Problems solved by technology

[0003] 1. When the double-ended wrench locks two board parts, it is impossible to estimate the fitting gap between the two boards after locking, and thus cannot judge the effect of locking, resulting in frequent fitting gaps If it is too large, the locking is not firm;

[0004] 2. When a double-ended wrench encounters an overstretched screw, it needs to use a tool such as a chisel to loosen the screw first, and then use a wrench for further disassembly. The chisel is relatively small. When it is not used in combination, the existing technology The double-ended wrench cannot complete the disassembly task independently;

[0005] 3. When using a wrench for hammering, because the wrench head is smooth and easy to slip, the hammer head is easy to slip sideways, and in severe cases, it will cause harm to people or objects around it.
