Abstract
The utility model relates to a tool for removing nuts or bolts on heavy mechanical equipment, in particular to a powerful adjustable fixed wrench, which comprises a wrench body and a hexagonal hole arranged on the same. A guide socket is arranged inside one end of the wrench body, a slider movably matched with the guide socket is arranged inside the guide socket, and a push bolt connected with the slider is disposed at the end of the guide socket. The slider, the push bolt and the guide socket are matched mutually, an actuating arm of the wrench is adjustable, and thereby force of the wrench can be adjusted, and multiple purposes are achieved. The wrench is simple in structure, convenient in production and suitable for industrial systematic production.
Description
Technical field
The utility model relates to the nut on a kind of dismounting heavy duty equipment or the instrument of bolt, particularly a kind of powerful adjustable type back-up wrench.
Background technology
Spanner generally is divided into back-up wrench and monkey wrench, and monkey wrench can be dismantled the little nut of size, but needs to regulate the manufacturing process complexity.In work progress, the dismounting of the open type large scale nut on the heavy construction plant equipment such as particularly all kinds of excavators, loading machine, all be to adopt old-fashioned back-up wrench, the nut of different models must adopt the back-up wrench of respective model, need the large-sized back-up wrench of standby multiple model, carry inconvenience, and run into large-sized nut of difficult dismounting, very difficult during dismounting.
Summary of the invention
The utility model is the defective at the conventional fixed spanner, provide a kind of can be according to the size of actual nut, by the spanner arm of force is regulated, thereby change the powerful adjustable type back-up wrench of its powerful size.
Goal of the invention of the present utility model is achieved in that a kind of powerful adjustable type back-up wrench, comprise wrench body and be arranged on hexagonal hole on the wrench body, the inside of described wrench body one end is provided with guide groove, be provided with in this guide groove and its slide block movingly, the guide groove end is provided with the push bolt that is connected with slide block.
Compare with traditional back-up wrench, cooperatively interacting of slide block in the utility model, push bolt, guide groove, the arm of force of wrench body is adjustable, thereby the effect that the powerful big or small generation that realizes spanner can be debugged, reach the purpose that a tool is used more, and this spanner structure is simple, and is convenient for production, is suitable for the production of industrialized system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Among the figure: wrench body 1, slide block 2, dormant bolt 3, push bolt 4, newel post 5, cannelure 6, guide groove 7, hexagonal hole 8.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Referring to accompanying drawing 1-2, in the present embodiment, this brute force adjustable type back-up wrench, the hexagonal hole 8 that comprises wrench body 1 and be arranged on the wrench body 1, the inside of wrench body 1 one ends is provided with guide groove 7, be provided with in this guide groove 7 and its slide block 2 movingly, the end of guide groove 7 is provided with the push bolt 4 that is connected with slide block 2.The blind holes that are provided with in the newel post 5 of push bolt 4 and the slide block 2 movingly, the two interlock.
The upper end of slide block 2 is " V " font clamping face, and this clamping face matches with the limit, hole of hexagonal hole 8.The angle that is somebody's turn to do " V " word clamping face is 120 °, and it parallels with the limit, hole of hexagonal hole 8.The end of push bolt 4 is a newel post 5, and this newel post 5 is provided with cannelure 6, and wrench body 1 is provided with the dormant bolt 3 that matches with this cannelure 6.
Push bolt 4 is being drawn slide block 2 and is being slided up and down in guide groove 7, and dormant bolt 3 the landing that can prevent push bolt 4 is set.Slide block 2 is in sliding process, and the spacing on the limit, hole of its clamping face and hexagonal hole changes, and the adjustable dimension scope of the spacing between the two is 70-130mm, so just can realize that powerful size can debug, and realizes that a tool uses more.
In order better to strengthen the brute force of spanner, the clamping of slide block 2 is faced the mountain and is designed to the hackle mark structure, can prevent that like this spanner from skidding in the process of degree of tightness nut.
