Problems solved by technology

At present, most of the adjustable torque screwdrivers on the market can only provide the maximum output torque for locking, and the other direction is basically infinite. This kind of screwdriver has many defects in engineering verification, and most of the structures are more complicated. , the production cost and maintenance cost are relatively high, which is not conducive to maintenance and replacement

Embodiment Construction

[0018] see Figure 1-3 , the present invention provides an adjustable torque driver 100 in an embodiment. The adjustable torque screwdriver 100 includes a sleeve 10 with adjustable length, a resistance part 20 installed on the sleeve 10, a rotating shaft 30 accommodated in the sleeve 10, a bit 40 connected to the rotating shaft 30 at one end and connected to the sleeve 10. and the elastic member 50 between the rotating shaft 30. The screwdriver bit 40 is used to turn the screw. The resistance part 20 and the rotating shaft 30 have a magnetic force that repels each other, and the contact area between the resistance part 20 and the rotating shaft 30 determines the magnitude of the magnetic force between the two. The larger the contact area, the greater the magnetic force, and the maximum torque that can be output The bigger it is, on the contrary, the smaller the magnetic force is, the smaller the maximum torque that can be output. When it is necessary to adjust the output ma...

Abstract

A torsion-adjustable screw driver comprises a length-adjustable sleeve and a screw driver head with one end accommodated in the sleeve. The torsion-adjustable screw driver is characterized in that the torsion-adjustable screw driver further comprises resistance parts and a rotating shaft making contact with the resistance parts; the resistance parts and the rotating shaft are both accommodated in the sleeve, the resistance parts are fixedly connected to the sleeve, and the resistance parts and one end of the rotating shaft interact with each other to provide resistance for preventing the rotating shaft from rotating relative to the sleeve; the other end of the rotating shaft is fixedly connected with one end of the screw driver head; the magnitude of the resistance for preventing the rotating shaft from rotating relative to the sleeve is in direct proportion to the contact area of the rotating shaft and the resistance parts; by controlling the contact area of the rotating shaft and the resistance parts, the resistance for preventing the rotating shaft from rotating relative to the sleeve is determined, and therefore the maximum torsion for rotating the rotating shaft is determined, and the maximum screwing torsion of the screw driver head is determined. According to the torsion-adjustable screw driver, bidirectional torsion adjustment can be achieved through the resistance between the resistance parts and the rotating shaft, a good examination effect in engineering examination is achieved, the structure is simple, and the screw driver head can be replaced by various screw driver heads.

Description

technical field [0001] The invention relates to a screwdriver, in particular to a two-way adjustable torque screwdriver. Background technique [0002] A screwdriver is an essential tool in life and work, and an adjustable torque screwdriver is one of them. At present, most of the adjustable torque screwdrivers on the market can only provide the maximum output torque for locking, and the other direction is basically infinite. This kind of screwdriver has many defects in engineering verification, and most of the structures are more complicated. , the production cost and maintenance cost are relatively high, which is not conducive to maintenance and replacement. Contents of the invention [0003] In view of this, it is necessary to provide a two-way adjustable torque screwdriver, so that the forward and reverse directions can be verified during engineering verification. [0004] An adjustable torque screwdriver, comprising a length-adjustable sleeve and a screwdriver bit wi...
