Description

Scissors with replaceable tool bit

Technical Field

The utility model relates to a scissors technical field especially relates to a scissors of removable tool bit.

Background

The scissors are double-edge tools for cutting sheet or linear objects such as cloth, paper, steel plates, ropes, round steel and the like, the two edges are staggered and can be opened and closed, and the scissors are distinguished in the industry in China due to the development of the textile industry.

However, the existing scissors cannot replace the scissors head, so that the universality of the scissors is reduced when the scissors are used, and the requirements on cutting under different conditions are met.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the existing scissors in the prior art can not be replaced by the scissors head, leading to the shortcoming that the universality is reduced when the scissors are used, and providing the scissors with a replaceable tool bit.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a scissors of removable tool bit, includes two support arms, two the support arm is the slope setting, and two support arm one ends are fixed with the arc shell fragment that resets jointly, two the support arm other end all is fixed with the connecting block, every the connecting block all is connected with the installation piece through angle adjustment mechanism, every installation piece side upper portion is fixed with spacing piece, and every installation piece side lower part all is fixed with spacing piece down, spacing piece and spacing piece symmetry down set up on, and spacing piece both sides both ends down all are connected with bolted connection spare jointly, every on the equal threaded connection in spacing piece top surface middle part has the location screw thread post, and the common centre gripping of spacing piece and spacing piece down has the scissors tool bit on same support arm.

Preferably, the angle adjusting mechanism comprises two connecting lugs clamped with the connecting block, bolts penetrating the connecting lugs and the connecting block are arranged at the bottoms of the two connecting lugs, and nuts are connected to the bolts in a threaded mode.

Preferably, the upper limiting piece and the lower limiting piece are the same in shape and size, and the middle parts of the upper limiting piece and the lower limiting piece are both arc-shaped.

Compared with the prior art, the utility model discloses following beneficial effect has: the utility model discloses a bolted connection spare on last spacing piece and the lower spacing piece can be fixed the scissors tool bit of different specifications, realizes the purpose of removable scissors tool bit, sets up the angle of carving of the adjustable scissors tool bit of installing on the support arm of angle adjustment mechanism in addition and closes the angle, so can make the scissors tool bit carve the degree of contact higher, and shearing effect is better, has solved the scissors and can not change the scissors tool bit, the problem that the commonality reduces when leading to the scissors to use.

Drawings

Fig. 1 is a schematic structural view of a pair of scissors with replaceable tool bits according to the present invention;

fig. 2 is an enlarged view of a point a in fig. 1.

In the figure: support arm 1, arc shell fragment 2 that resets, connecting block 3, installation piece 4, go up spacing piece 5, spacing piece 6 down, bolted connection 7, location screw thread post 8, scissors tool bit 9, engaging lug 10, bolt 11, nut 12.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

As shown in figure 1-2, a scissors with replaceable cutting head comprises two support arms 1, wherein the two support arms 1 are arranged obliquely, one end of each support arm 1 is jointly fixed with an arc-shaped reset spring piece 2, the other end of each support arm 1 is fixedly provided with a connecting block 3, each connecting block 3 is connected with a mounting block 4 through an angle adjusting mechanism, the upper part of the side surface of each mounting block 4 is fixedly provided with an upper limiting piece 5, the lower part of the side surface of each mounting block 4 is fixedly provided with a lower limiting piece 6, the upper limiting piece 5 and the lower limiting piece 6 are symmetrically arranged, both ends of the two sides of the upper limiting piece 5 and the lower limiting piece 6 are jointly connected with a bolt connecting piece 7, the middle part of the top surface of each upper limiting piece 5 is in threaded connection with a positioning threaded column 8, the upper limiting piece 5 and the lower limiting piece 6 on the same support arm 1 jointly clamp a scissors cutting head 9, when the scissors are, can make two scissors tool bits 9 tailor cloth etc, when needing to be changed scissors tool bit 9, earlier unscrew all bolted connection spare 7, then unscrew location screw thread post 8, so can take off original scissors tool bit 9, then install new scissors tool bit 9 between last spacing piece 5 and lower spacing piece 6, screw up all bolted connection spare 7 again and location screw thread post 8 alright fix new scissors tool bit 9 on two support arms 1, then adjust two scissors tool bits 9 to suitable angle utilizing angle adjustment mechanism, so just can carry out subsequent tailorring, moreover, the operation is simple, it can not change scissors tool bit 9 to have solved the scissors, lead to the problem that the commonality reduces when the scissors uses.

The angle adjusting mechanism comprises two connecting lugs 10 clamped with the connecting block 3, the bottoms of the two connecting lugs 10 are provided with bolts 11 penetrating through the connecting lugs 3, the bolts 11 are connected with nuts 12 in a threaded mode, when the angle of the scissor bit 9 is adjusted, the nuts 12 on the bolts 11 are unscrewed, then the scissor bit 9 can be rotated to a proper angle, and the nuts 12 are screwed again.

Go up spacing piece 5 and 6 shapes of spacing piece down and size homogeneous phase the same, and go up spacing piece 5 and 6 middle parts of spacing piece down and all set up to the arc, through all set up to the arc at last spacing piece 5 and 6 middle parts of spacing piece down and conveniently carry out fixed mounting to cylindrical tool bit and flat type's scissors tool bit.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the principles of the present invention may be applied to any other embodiment without departing from the spirit and scope of the present invention.
