Description

A kind of advantageous torque spanner

Technical field

The utility model relates to torque spanner fields, are specifically related to a kind of advantageous torque spanner.

Background technique

Torque spanner is called torque wrench, torque spanner, torque adjustable spanner, is one kind of spanner, is generally divided into electronic Torque spanner and manual torque spanner.Torque spanner not only can it is just tight again can eventually tightly, its use is first to adjust torque, then fasten spiral shell Bolt.The main feature of torque spanner is exactly: can set torque, and torque is adjustable.The general fastening for high-strength bolt Will be first just tight tight eventually again, and every step requires stringent torque demand.The first tight and end of high-strength bolts is tight all Constant torque wrench must be used.

Existing torque spanner versatility is not very by force that needing corresponding component to be matched just can be general, is increased in this way Use cost is added, has needed to be improved.

Utility model content

The technical problems to be solved in the utility model is the defect for overcoming prior art torque spanner to use poor universality, is mentioned For a kind of advantageous torque spanner.

In order to solve the above technical problems, the utility model is the following technical schemes are provided: a kind of advantageous torque spanner, including pull At hand, ring body is installed in the inside activity of the driving end, and the inner ring of ring body is operating space, opens up marmon clamp on the inside of the ring body Layer, symmetrically placed operating stick and anchorage bar in the annular gap, the operating stick are screw structure, the both ends of the operating stick It is flexibly connected with the side wall of the annular gap of ring body, the operating stick is vertical to installation, the operation with adjacent anchorage bar The middle part of bar is cylinder, and tapped through hole is symmetrically opened up on the anchorage bar, and the tapped through hole internal screw thread passes through corresponding operation The screw thread body of rod of bar.

Further, the anchorage bar is rectangular configuration, and the top in the opposite face of anchorage bar cuts to form arc angle.

Further, the cylinder is located in operating space.

The utility model has the beneficial effect that a kind of advantageous torque spanner compared with prior art, structurally reasonable, makes With conveniently, the ratchet header structure of spanner is mainly improved, operating stick and anchorage bar are set, to realize the behaviour of various types of bolt Make, specific very strong versatility and flexibility, and operates extremely easy, ultrahigh in efficiency.

Figure label are as follows: 1- driving end；2- ring body；The operating space 3-；4- operating stick；5- anchorage bar；6- cylinder；7- screw thread is logical Hole；8- arc angle.

Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

Referring to figs. 1 to known to Fig. 2: a kind of advantageous torque spanner, including driving end 1, the inside activity peace of the driving end 1 Ring body 2 is filled, the inner ring of ring body 2 is operating space 3, and the inside of the ring body 2 opens up annular gap, symmetrically puts in the annular gap Operating stick 4 and anchorage bar 5 are set, the operating stick 4 is screw structure, the annular gap at the both ends and ring body 2 of the operating stick 4 Side wall is flexibly connected, and the operating stick 4 is vertical to installation with adjacent anchorage bar 5, and the middle part of the operating stick 4 is cylinder 6, Tapped through hole 7 is symmetrically opened up on the anchorage bar 5,7 internal screw thread of tapped through hole passes through the threaded rod of corresponding operating stick 4 Body.

The anchorage bar 5 is rectangular configuration, and the top in the opposite face of anchorage bar 5 cuts to form arc angle 8, convenient for the top of bolt Portion is caught in.

The cylinder 6 is located in operating space 3, is convenient for touch operation.

The principles of the present invention and advantage: the improvement is mainly improved in the original port position of driving end 1, will It polishes out annular gap, operating stick 4 and anchorage bar 5 is installed, according to the top size of bolt, rotating cylindrical 6, so that anchorage bar 5 is close to each other or separate, so be suitble to bolt top fix, the top of bolt between 8 insertion operation bar 4 of arc angle, Spanner can be operated.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model Protection scope within.
