Problems solved by technology

However, the existing wrench is very inconvenient to use, and it is labor-intensive and time-consuming, so it is not practical
When a vise-type wrench is used to turn the bolt, the mouth end of the wrench head is relatively flexible, but it requires a lot of grip force to hold the handle tightly, making the wrench easy to slip and causing great inconvenience to the user.

Embodiment Construction

[0009] see figure 1 , the top of the cavity connecting claw 4 is equipped with a fixed wrench 9 and a movable wrench 8, and the main wrench handle 1 adopts a connecting pin 3 to connect the cavity connecting claw 4, and between the left and right cavity connecting claws, the top of the main wrench handle 1 is set There are arc-shaped teeth 5, and the arc-shaped teeth 5 are connected with bar-shaped teeth 6, and the bar-shaped teeth 6 are integrated with the movable wrench 8; The cavity is riveted with claw riveting pin 7.

[0010] When the main wrench handle 1 and the auxiliary wrench handle 2 are pulled, the tooth position between the arc-shaped teeth 5 and the bar-shaped teeth 6 at the top of the main wrench handle 1 can be adjusted to change the distance between the adjustable wrench 8 and the fixed wrench 9. The size width (arc tooth 5 and tooth bar connecting pawl 6 are regular buckles and can be used for adjusting at any time). This manufacturing technique is relativel...

Abstract

A tooth fastening adjustable spanner is composed of a master handle with arc rack bar on its front end, a linking jaw with cavity and front fixed jaw and pivoted to the said master handle, and a movable jaw with a straight rack bar engaged with said arc rack bar.

Description

[technical field] [0001] The invention relates to the technical field of wrenches, in particular to a buckle type adjustable wrench. [Background technique] [0002] At present, the commonly used wrench mainly consists of a movable wrench, a fixed wrench and a force-applying handle connected with the fixed wrench. The movable wrench and the fixed wrench are stuck behind the hexagonal nut, and then placed on the handle. Apply a pulling force to make the nut achieve the effect of locking and dismounting. However, the existing wrenches are inconvenient to use, labor-intensive and time-consuming, and are not practical. When using a vise type wrench to pull the bolt, the mouth end of the wrench head is relatively flexible, but a large grip is required to hold the handle tightly, which makes the wrench slip easily and causes great inconvenience to the user. [Content of the invention] [0003] The object of the present invention is to provide a buckle-type adjustable wrench to s...
