Abstract

The utility model provides a novel chuck spanner which comprises a spanner stick and a spanner rod, wherein, the spanner rod comprises a rod body and a head part; planes are milled on the front and the rear sides of the spanner stick and the rod body of the spanner rod. The novel chuck spanner of the utility model can increase the grasping force and the hand feeling of the spanner, is more comfortable to use, and is more convenient to perform remote and accurate operation for the spanner, in addition, characters and pictures marked on the planes can not cause deformation, thereby being helpful for improving the quality of the spanner product and the obvious degree of the marks.

Description

A kind of new-type chuck handle

Technical field

The utility model relates to a kind of chuck handle.

Background technology

In the prior art, chuck comprises disk body, the claw of chuck, be provided with parcel in the disk body, the front end face of parcel is threaded with claw, disk body circumferentially evenly is provided with several tooling holes along it, tooling hole is generally three, is provided with the bevel gear that drives parcel in the described tooling hole, and the afterbody of bevel gear is provided with driving hole.When operation, chuck handle is inserted driving hole, by turning spanner, drive bevel gear, parcel rotation, make the claw motion.The main body of present chuck handle is a circular cross-section, is not easy to the operator and controls when accurate operation.

Summary of the invention

Technical problem to be solved in the utility model provides the new-type chuck handle that a kind of operator of helping controls.For this reason, the utility model by the following technical solutions: it comprises spanner rod and wrenching bar, and wrenching bar comprises shaft and head, and the both sides, front and back of described spanner rod and wrenching bar shaft are milled with the plane.Owing to adopt the technical solution of the utility model, the utility model can increase the hand grip and the feel of spanner, use more comfortable, be more convenient for to the trickle of spanner and accurate operation, and, mark or character, figure can not cause distortion on above-mentioned plane, help to improve the product quality and the sign boldness of spanner.

Description of drawings

Fig. 1 is the schematic diagram of embodiment that the utility model provides.

Fig. 2 is the upward view of Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 1.

The specific embodiment

With reference to accompanying drawing.The utility model comprises spanner rod 1 and wrenching bar 2, wrenching bar comprises shaft 21 and head 22, the head of described wrenching bar is four directions or six square toes, described spanner rod and wrenching bar connect into T shape, the front and back both side surface of described spanner rod and wrenching bar shaft, also be among Fig. 1 towards paper and dorsad the both side surface of paper be milled with

plane

10,20, the plane 10 on the spanner rod and the plane 20 of wrenching bar shaft are parallel to each other.

With reference to Fig. 1, when implementing, described spanner rod can be that the whole front and back both side surface along its length direction is described plane 10, and like this, the spanner processing and manufacturing of can being more convenient for also can make spanner to operator's hand shape with grip custom and have wider adaptive.Perhaps, described spanner rod can be that both side surface is described plane 10 before and after its length direction local

With reference to Fig. 1, gradually thin below described shaft 21 middle parts, rod body near the wrenching bar head is divided into the gradually thin frustum of a cone 23, described plane 20 is in the shaft part of the frustum of a cone more than 23, like this, can make spanner to operator's hand shape and grip custom have wider adaptive, simultaneously, the meticulous control of operator of also being more convenient for to spanner.

Can be carved with literal and/or figure on described plane 10 and the plane 20.
