Problems solved by technology

The existing percussion wrench design is relatively simple, just set the handle on the side of the sleeve
However, when the user hits the handle with a hammer, it is often difficult to grasp the center position of the handle, resulting in uneven stress on the handle and poor stability when the sleeve rotates.
Moreover, the existing percussion wrench cannot be tightly fastened on the head of the bolt, so that when the handle of the wrench is hit with a hammer, the sleeve cannot stably clamp the head of the bolt, and the operability and stability are poor.

specific Embodiment approach

[0015] figure 1 with figure 2 Show the specific embodiment of a kind of stable knocking wrench of the present invention: combine figure 1 with figure 2 , the stable percussion wrench includes a cylindrical sleeve 1, the center of the bottom surface of the sleeve 1 is provided with a regular hexagonal prism bolt hole 8, the size of the bolt hole 8 is the same as that of the bolt head, and the bolt hole 8 can be Cover the head of the bolt so that the sleeve 1 can turn the bolt in the threaded hole.

[0016] Such as figure 1 As shown, the top surface of the sleeve 1 is connected with a disc-shaped pressing plate 4 through two vertically arranged springs 6, the pressing plate 4 is parallel to the top surface of the sleeve 1, the top surface of the pressing plate 4 is provided with a handle 5, and the side of the sleeve 1 A flat plate-shaped handle 2 is vertically provided, and a cylindrical hammering column 3 is arranged on the handle 2. The axis of the hammering column 3 is...

Abstract

The invention discloses a stable impact spanner, and relates to the field of mechanical tools. When the stable impact spanner is used, the head of a bolt can be sleeved with a bolt sleeve hole of a sleeve, a user holds a pull handle with one hand to push and press a pressing plate, the sleeve is tightly attached to the head of the bolt by utilizing the compression pre-tightening force of springs,and the user holds a hammer with the other hand to aim at aiming conical faces on the end faces of a hammering column for hammering. The user can hammer the stable impact spanner more accurately, thena handle can bear more horizontal impact force, then the sleeve can stably rotate, the bolt can be quickly and stably screwed or unscrewed, and the operation stability of the spanner is improved.

Description

technical field [0001] The invention relates to the field of mechanical tools, in particular to a stable percussion wrench. Background technique [0002] A percussion wrench refers to a mechanical tool with the hand-held end as the percussion end and the front end as the working end. The percussion wrench is suitable for occasions where the working space is narrow and ordinary wrenches cannot be used. The existing percussion wrench is relatively simple in design, and only a handle is provided on the side of the sleeve. And when the user knocks the handle with a hammer, it is often difficult to grasp the central position of the handle, which causes the handle to be stressed unevenly, and the stability of the sleeve is not good when it is rotated. Moreover, the existing percussion wrench cannot be tightly fastened on the head of the bolt, so that when the handle of the wrench is hit with a hammer, the sleeve cannot stably block the head of the bolt, and the operability and s...
