Problems solved by technology

[0004] figure 1 It is a schematic diagram of the structure of the inner angle wrench provided by the prior art. Regardless of the angle of the wrench, in the specific implementation, in order to facilitate insertion and force, there is a gap between the inner angle of the existing clamping part 1' and the screw, but in When encountering a vertical and deep installation point, it is difficult to put the screw into the screw hole accurately; it is difficult to remove the screw smoothly after the disassembly is completed

Embodiment 1

[0031] An inside angle wrench, such as Figure 2-4 As shown, it includes: a wrench body, the wrench body includes a clamping part 1 and a connecting part 2 connected to the clamping part 1, and the clamping part 1 is provided with a plurality of clamping surfaces 11, at least one of which is An installation groove 3 is opened on the clamping surface 11 , and a rotating handle 6 is connected to the top of the connecting portion 2 . The mounting groove 3 is installed with an elastic member, and the elastic member includes a pressing section 4 that can protrude or shrink under the action of an external force, and a pressing section 5 that is connected to the pressing section 4 through a fulcrum. The pressing section 4 includes a pressing section body, a connecting piece 42 and a pressing piece 41. Vertically connected, the end of the pressing section body connected to the pressing section 4 is a fulcrum, the pressing section 4 is arranged in the installation groove 3, the fulcru...

Embodiment 2

[0043] An inside angle wrench, such as Figure 5-6 As shown, it includes: a wrench body, the wrench body includes a clamping part 1 and a connecting part 2 connected to the clamping part 1, and a rotating handle 6 is connected to the top of the connecting part 2. The clamping portion 1 is provided with a plurality of clamping surfaces 11 , at least one of the clamping surfaces 11 is provided with a mounting groove 3 , and a pressing section 4 is mounted on the mounting groove 3 .

[0044] The pressing section 4 can slide along the length direction of the installation groove 3 under the push of an external force. The depth of the groove gradually becomes shallower. When the pressing section 4 slides in the installation groove 3 to the limit position at the clamping part 1, at least part of it protrudes from the clamping surface 11 and abuts against the groove of the screw head to be installed. On the inner wall, when the pressing section 4 slides in the installation groove 3 t...

Abstract

The invention relates to the technical field of fastening equipment, in particular to a hex wrench. The hex wrench comprises a wrench body, wherein the wrench body comprises a blocking part and a connecting part connected onto the blocking part; a plurality of blocking surfaces are formed in the blocking part; a mounting slot is formed in at least one blocking surface; an elastic part is mounted in the mounting slot; and the elastic part comprises a butting section which can stretch out or draw back under action of external force, and a pressing section which is connected with the resisting section. The invention further provides a using method for the hex wrench. By virtue of a matched structure of the resisting section which can stretch out or draw back under action of external force and the mounting slot, the butting section abuts against the inner wall of a bolt head slot to realize clamping and releasing of bolts when the hex wrench is used for taking the bolts, so that the problem that bolts are not easily taken out and easily drop when the hex wrench is adopted for mounting the bolts in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of fastening equipment, in particular to an inner angle wrench. Background technique [0002] Allen wrench is also called Allen wrench. Common English names are "Allen key (or Allen wrench)" and "Hex key" (or Hexwrench). It exerts force on the screw through torque, which greatly reduces the force intensity of the user, and is an indispensable and powerful tool in industrial manufacturing. [0003] Among the installation tools involved in the modern furniture industry, although the Allen wrench is not the most commonly used, it is the best. During the screw installation process of the existing inner angle wrench, the inner angle is inserted into the groove of the screw head, and the screw is rotated to tighten or loosen. Existing inner angle wrench has inner triangle wrench, inner square wrench and inner hexagonal wrench etc. [0004] figure 1 It is a schematic diagram of the structure of the inner angle...
