Description

Multifunctional wrench head for fixing force

Technical Field

The utility model relates to the technical field of fixed force installation tools, in particular to a multifunctional wrench head for fixed force.

Background

During final assembly, parts needing constant force installation are often involved, however, the sizes of some parts are often not matched with the sizes of common constant force wrenches, constant force cannot be performed, and subsequent assembly work cannot be completed. At present, outfield refitting is relatively heavy in task, a plurality of systems need to use a constant force wrench, and the size of the constant force wrench needs to use various sizes, so that the number of tools to be carried is large, the carrying capacity is heavy, and the tool loss accident is easy to cause.

SUMMERY OF THE UTILITY MODEL

The purpose of the utility model is: a multi-purpose wrench head for setting force is provided. The utility model overcomes the problem that the sizes of parts are not matched with the sizes of common fixed-force wrenches, reduces the weight of tools carried by workers, and has reliable clamping and strong applicability.

The technical scheme of the utility model is as follows: a multifunctional wrench head for fixing force comprises a main body component, wherein one end of the main body component is provided with a connecting port, the other end of the main body component is provided with a fork lug, and a fork arm of the fork lug is in threaded connection with an adjusting bolt; the central axis of the adjusting bolt is perpendicular to the central axis of the main body component.

In the multifunctional wrench head for fixing force, the adjusting bolt is further provided with a pre-tightening nut, and the pre-tightening nut can be attached to the outer side wall of the yoke after rotating.

In the multifunctional wrench head for fixing force, the pre-tightening nut is a hexagonal thin nut.

In the multifunctional wrench head for fixing force, the two fork arms of the fork lug are respectively in threaded connection with an adjusting bolt, the two adjusting bolts are arranged oppositely, and the central axes of the two adjusting bolts coincide.

In the multifunctional wrench head for fixing force, the maximum value of the distance D between the opposite surfaces of the two adjusting bolts is 54 mm.

In the multifunctional wrench head for fixing force, the main body member and the adjusting bolt are both made of carbon structural steel.

The utility model has the advantages that: the utility model well realizes the multifunctional force fixing effect, and can clamp and fix the force of all parts with the size less than or equal to 54mm under the condition of enough operation space; the problem of spare part size and the size of constant force spanner commonly used mismatch is solved to alleviate workman's instrument weight problem of carrying, its simple structure, safe and reliable, loading and unloading are convenient, and the suitability is strong, therefore the practicality is better, has great practical value.

Fig. 1 is a schematic structural view of the present invention.

Reference numerals: 1-main body component, 2-connecting port, 3-fork ear, 4-adjusting bolt and 5-pre-tightening nut.

Detailed Description

The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.

Example 1. A multifunctional wrench head for fixing force is formed as shown in figure 1 and comprises a main body component 1, wherein one end of the main body component 1 is provided with a connecting port 2, the other end of the main body component 1 is provided with a fork lug 3, and a fork arm of the fork lug 3 is in threaded connection with an adjusting bolt 4; the central axis of the adjusting bolt 4 is perpendicular to the central axis of the main body member 1.

The adjusting bolt 4 is further provided with a pre-tightening nut 5, and the pre-tightening nut 5 can be attached to the outer side wall of the fork arm after rotating.

The pre-tightening nut 5 is a hexagonal thin nut. The hexagonal thin nut is used for fixing the clamping capacity of the adjusting bolt 4, and the adjusting bolt 4 is guaranteed not to loosen after being clamped with the fixed-force component.

The two fork arms of the fork lug 3 are respectively in threaded connection with an adjusting bolt 4, the two adjusting bolts 4 are arranged oppositely, and the central axes are overlapped. The adjusting bolt 4 can adjust the screwing-out length according to the size of the fixed-force component.

The maximum value of the distance D between the opposite surfaces of the two adjusting bolts 4 is 54 mm.

The aforementioned main body member 1 and the adjusting bolt 4 are each composed of carbon structural steel.

When in use, the wrench head is connected to the fixed-force wrench through the connecting port 2, the adjusting bolt 4 is screwed according to the fixed-force component to extend to a preset length, and then the fixed-force component can be screwed.
