Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] like figure 1 As shown, a torque screwdriver of the present invention includes a handle 1 and a knife shaft 2, the handle 1 is connected to the knife shaft 2, the handle 1 is connected to the first connecting rod 3, and the two ends of the first connecting rod 3 are connected to the torque regulator 4 and The fastening disc 5 and the torque regulator 4 have adjusted the torque in advance. The tightening disc 5 can fix the handle 1. The torque regulator 4 is connected to the cutter shaft 2. There is a screw hole 6 in the middle of the cutter shaft 2 to match the mounting bolt. In the middle of the shaft 2, there is a rotating shaft sharp knife 7, the rotating shaft sharp knife 7 is used as a spare, the handle 1 is connected to a handle 8, and the bottom of the handle 8 is provided with a back-frust force base 9, which prevents the use of a large f...

Abstract

The invention discloses a torque screwdriver. The torque screwdriver comprises a handle and a cutter shaft which are connected with each other, wherein the handle is connected with a first connecting rod, a torque adjuster and a tightening disk are connected with two ends of the first connecting rod, the torque adjuster is connected with the cutter shaft, a bolt hole matched with a mounting bolt is formed in the middle of the cutter shaft, a rotating shaft sharp cutter is arranged in the middle of the cutter shaft, a grip is connected with the back of the handle, a recoil force base is arranged at the bottom of the grip, and a reset spring is arranged between the handle and the grip. With the adoption of the torque screwdriver, torque is well adjusted in advance by the aid of the torque adjuster, the tightening disk can well fix the handle, the recoil force base is arranged at the bottom of the grip, the condition that recoil power support is inhibited due to large applied force in the screwing process is prevented, the reset spring is arranged between the handle and the grip, the condition that the grip is damaged easily due to the large recoil force is prevented, and the torque screwdriver is applicable to various instruments, meters and electromechanical devices.

Description

technical field [0001] The invention relates to a torque screwdriver and belongs to the field of screwdrivers. Background technique [0002] The connection quality of the torque screwdriver to the fastener directly affects the reliability of various instruments, electromechanical equipment, household appliances and other products. Therefore, torque tools such as torque screwdrivers are gradually being used in industrial production more and more. However, the existing screwdrivers have limited torque and are limited in use. Torque screwdrivers need a lot of power to suppress the backlash, because in the process of twisting the screw, the required force is very large. Therefore, a new technology needs to be sought to solve this problem. Contents of the invention [0003] The object of the present invention is to provide a torque screwdriver with convenient twisting. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: ...
