Description

A kind of tinsmith snips of quick change head soon

Affiliated technical field

The utility model relates to the hand-operated tools field, specifically a kind of tinsmith snips of quick change head soon.

Background technology

At present both at home and abroad scissors generally all is that head adopts riveting to be connected with handle or is threaded, and scissors bit is not easy to change, and when left cut if desired, right cut, vertical cut, use the tangential scissors of difference, the cost of increase tool using, and carry inconvenience.

Summary of the invention

The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of rational in infrastructure, and cost is low, and operation, easy to use can be changed the tinsmith snips of cutter head fast.

The utility model solves the scheme that its technical problem takes: a kind of tinsmith snips of quick change head soon, by scissors bit, handle is formed, the afterbody of scissors bit has pin-and-hole, the top of handle is connected with bolt, the top that it is characterized in that the handle circular hole is provided with socket, be provided with cannelure in the socket, be provided with jump ring in the cannelure, latch is provided with two cannelures, and the cannelure of its root is the conical surface downwards, and the cannelure of afterbody upwards is the conical surface, be provided with the elasticity positioning seat in the handle, the afterbody of scissors bit inserts on the elasticity positioning seat, and the pin-and-hole that latch is pressed into process scissors bit afterbody in the socket enters in the handle circular hole, and scissors bit is fixedlyed connected with handle.

Owing to adopt latch to insert in the socket, the jump ring in the cannelure enters in the cannelure on the latch, and positioning and locking pulls up the replaceable scissors bit of latch, and latch is pressed in the socket, and scissors bit and handle are fastenedly connected, and is easy to manufacture, and production, use cost are low.

Description of drawings

The utility model is described in detail by embodiment below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Mark among the figure: 1, scissors bit, 2, the iron handle, 3, latch, 4, plastic handle, 5, the spring positioning seat, 6, rivet, 7, jump ring, 8, socket.

The specific embodiment

By Fig. 1, shown in Figure 2: a kind of tinsmith snips of quick change head soon, by scissors bit 1, handle 2 is formed, the afterbody of scissors bit 1 has pin-and-hole, iron handle 2 tops are connected with bolt, top at handle 2 circular holes is provided with socket 8, be provided with cannelure in the socket 8, be provided with jump ring 7 in the cannelure, latch 3 is provided with two cannelures, the cannelure of its root is the conical surface downwards, and the cannelure of afterbody upwards is the conical surface, is provided with elasticity positioning seat 5 in the handle 2, it is fixed in the handle 2 by rivet 6, be used to limit the position of scissors bit, the afterbody of scissors bit 1 inserts on the elasticity positioning seat 5, and the pin-and-hole that latch is pressed into process scissors bit afterbody in the socket enters in the handle circular hole, scissors bit is fixedlyed connected with handle, plastic handle 4 is installed in iron handle 2 outsides.The utility model is rational in infrastructure, easily make, operation, easy to use, can tangentially change left cut according to difference, right cut, the vertical cut scissors bit, pull up the cannelure that latch 3 makes afterbody and rise to the position that jump ring 7 can enter, extract scissors bit 1 out, take out the scissors bit that needs replacing, the afterbody of its scissors bit 1 is inserted in the iron handle 2, its scissors root is entered on the spring positioning seat 5, depress latch 3, because the cannelure of latch 3 afterbodys upwards is the cannelure bottom of the conical surface and root and is the conical surface, latch 3 can be entered fast and passes through to make jump ring 7 in the cannelure of latch 3 roots in the circular hole of scissors bit 1 afterbody, scissors bit and handle can be fixed together, therefore can realize changing fast scissors bit.
