Multifunctional electric wrench

Abstract

The invention discloses a multifunctional electric wrench comprising an output shaft, a transmission shaft, a steel ball (5), a pounding head (6), a compression spring (7), a case (8), a gear speed reduction box (9) and a motor (10), wherein the head part of the transmission shaft (4) is inserted into the end face slot of the output shaft (1); the combination part of the transmission shaft (4) and the output shaft (1) is provided with a clutch mechanism which comprises a poking rod (2) and a clutch steel bal (3); a poking rod central hole (12) is formed on the output shaft, the radial direction of the transmission shaft (4) is provided with a clutch steel ball hole (14), and the poking rod (2) is axially and movably arranged on the poking rod central hole (12); and the clutch steel ball (3) is arranged on the clutch steel ball hole (14) of the transmission shaft (4), the end face slot of the output shaft (1) is provided with a clutch groove (15) matched with the clutch steel ball (3), and the poking rod (2) extends into the central hole of the transmission shaft (4). Based on the structure, the multifunctional electric wrench has the advantages that structure is simple and reasonable, operation is convenient, working is stable and reliable, pounding and non-pounding heads can be mutually changed, one electric wrench has multiple functions, and the like.

Description

technical field [0001] The invention relates to an electric tool, in particular to a multifunctional electric wrench that can be used not only as an electric wrench but also as an electric drill, an electric impact drill and an electric screwdriver. Background technique [0002] The impact electric wrench is an electric tool powered by a motor, and the output shaft is driven by a gear reducer and an impact mechanism to generate impact torque to quickly disassemble bolts or nuts. Chinese patent discloses a kind of electric wrench, and its patent number is 200520069268.7, and it comprises gear box body, the machine cover with handle, the motor that is connected in the machine cover, gear reduction mechanism and impact sleeve and wrench head, and gear box body passes through The middle cover is fixedly connected with the hood, and the gear reduction mechanism includes a gear shaft connected to the middle cover and the gear box, a double gear connected to the gear shaft, a main ...

AI Technical Summary

Problems solved by technology

[0003] But there are following deficiencies in the use process: one, the existing impact type electric wrench is mainly suitable for dismounting larger bolts or nuts, when dismounting less bolts or nuts, due to the greater impact force, the bolts or nuts easily damaged

Second, the impact electric wrench has a single function and can only be used to disassemble bolts or nuts, and cannot be used as other electric tools

In response to the above problems, many manufacturers and people of insight have developed and developed, but so far no ideal products have come out.
