Abstract

The utility model discloses a wrench with a flower-shaped jaw and a movable head. The wrench with the flower-shaped jaw and the movable head comprises a snap ring, a wrench head and a handle, the snap ring is connected with the handle as a whole, the inner peripheral wall of the snap ring is in the shape of a polygon, the outer peripheral wall of one end of the wrench head is prismatic, the wrench head is in contact and matches with the inner peripheral wall of the snap ring through the prismatic outer peripheral wall, the inner peripheral wall of the other end of the wrench head is in the shape of a quincunx, the axial transition surface between every two adjacent quincunx-shaped inner walls is provided with two grooves at intervals, and the transition surface of the quincunx-shaped inner peripheral wall is in contact with the prismatic bolt head of a bolt. The wrench with the flower-shaped jaw and the movable head can solve the problems such as narrow application scope, operation difficulty and carrying inconvenience of existing fixing wrenches.

Description

A fancy top spanner alive

Technical field

The utility model belongs to field of tool, especially relates to a kind of fancy top spanner alive.

Background technology

The spanner of selling in the market has back-up wrench and monkey wrench two classes, and back-up wrench is manufactured according to the nut model of national Specification, has the fixing trade mark, and a kind of spanner of the trade mark can only corresponding a kind of nut, and the scope of application is little.The bayonet socket of existing back-up wrench mostly is polygon, just can snap in operation inconvenience in the time of card nut after need to aiming at completely.The spanner that needs different model while work at different operating position, the amount of carrying is large, very inconvenient to working.

Summary of the invention

The purpose of this utility model is to provide a kind of fancy top a spanner alive, and it is little that it can solve the existing back-up wrench scope of application, and operation inconvenience, carries the problems such as inconvenience.

The purpose of this utility model is achieved in that a kind of fancy top spanner alive, as shown in Figure 1, comprise snap ring, driving end, handle, snap ring and handle are connected as a single entity, the internal perisporium of snap ring is polygon, one end periphery wall of driving end is prismatic, the driving end cooperation that contacts with the internal perisporium of snap ring by prismatic periphery wall, the other end internal perisporium of driving end is quincunx, on axial transitions face between every two adjacent quincunx inwalls, all interval is arranging two grooves respectively, and the transition face of quincunx internal perisporium contacts with the prismatic bolt head of bolt.

The utility model driving end is movable, has different models, can change corresponding driving end, skidding when the polygon contact-making surface between snap ring and driving end and the polygonal outer shape of driving end can better prevent from rotating to different nuts.The quincunx fancy top internal perisporium of driving end is more easily convenient in the time of cover nut.The utility model is reasonable in design, simple and reliable for structure, and cost is lower; The scope of application is wide, and clamping speed is fast, easy to operate.

Brief description of the drawings

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is perspective view of the present utility model;

Fig. 2 is local structure for amplifying schematic diagram of the present utility model.

Detailed description of the invention

A kind of fancy top spanner alive, as shown in Figure 1 and Figure 2, comprise snap ring 1, driving end 2, handle 3, snap ring 1 is connected as a single entity with handle 3, the internal perisporium 8 of snap ring 1 is polygon, one end periphery wall 7 of driving end 2 is prismatic, driving end 2 cooperation that contacts with the internal perisporium 8 of snap ring 1 by prismatic periphery wall 7, the other end internal perisporium 6 of driving end 2 is quincunx, on axial transitions face between every two adjacent quincunx inwalls, all interval is arranging two grooves respectively, and the transition face of quincunx internal perisporium contacts with the prismatic bolt head 5 of bolt.

The utility model driving end is movable, has different models, can change corresponding driving end, skidding when the polygon contact-making surface between snap ring and driving end and the polygonal outer shape of driving end can better prevent from rotating to different nuts.The quincunx fancy top internal perisporium of driving end is more easily convenient in the time of cover nut.

Claims

1. a fancy top spanner alive, comprise snap ring, driving end, handle, it is characterized in that: snap ring and handle are connected as a single entity, the internal perisporium of snap ring is polygon, one end periphery wall of driving end is prismatic, the driving end cooperation that contacts with the internal perisporium of snap ring by prismatic periphery wall, the other end internal perisporium of driving end is quincunx, on axial transitions face between every two adjacent quincunx inwalls, all interval is arranging two grooves respectively, and the transition face of quincunx internal perisporium contacts with the prismatic bolt head of bolt.
