Description

A kind of claying knife

Technical field

The utility model relates to a kind of claying instrument of building finishing industry, relates in particular to a kind of claying knife.

Background technology

At present, the claying knife of Chu Xianing on the market, cutter hub and handle of a knife all are connected as a single entity, and are difficult for separately, and the cutter hub sheet that is rectangle is fixedly connected on the handle of a knife below in a horizontal manner.Various needs according to work progress, the cutter hub of claying knife is different, sometimes the periphery that requires cutter hub is linear, sometimes the part periphery indention that needs cutter hub, sometimes require the part periphery of cutter hub to be multiple tooth shape at interval, this just requires the constructor need get all the various claying knifes ready at the construction field (site), because cutter hub and handle are connected as a single entity, volume is bigger, and it is very inconvenient to carry.In addition, also can only change wholely claying knife when cutter hub weares and teares, like this, still intact handle of a knife can't utilize again, causes the wasting of resources.

Summary of the invention

The purpose of this utility model provides the claying knife that a kind of handle of a knife can load and unload as required flexibly, cutter hub is replaceable, easy to carry.

For achieving the above object, claying knife of the present utility model comprises cutter hub and handle of a knife, and cutter hub is microscler sheet, and is connected in the handle of a knife below in a horizontal manner, and raised line is arranged in the middle of the one side that cutter hub contacts with handle of a knife; Handle of a knife is made of seat handle and bar shaped, and one side relative with handle on the seat is had and the corresponding breach of raised line, and cutter hub is socketed in the breach of seat by raised line, and detent mechanism is arranged on the raised line.

More firm for handle of a knife and cutter hub are connected in use, the both sides of above-mentioned raised line are fluted, and there is the flange corresponding with groove seat breach two inboards.

Detent mechanism on the above-mentioned raised line is two position-limitting pins that are positioned on the raised line and protrude in the raised line surface, and wherein a lower end is connected with spring, and the spring other end is fixed in cutter hub; The distance of two position-limitting pins is the length of seat.

Claying knife of the present utility model has following advantage:

1, handle of a knife can make up and separate neatly with cutter hub, and is easy to loading and unloading, do not need any instrument.

2, for different cutter hubs, load onto the raised line of same specification, can reach the purpose that a handle of a knife is common to the multitool body.

3, cutter hub when wearing and tearing, can a tool changing body, not tool changing handle, economical with materials.

When 4, not using, handle of a knife can unload, and is convenient for carrying.

The specific embodiment

Claying knife shown in Figure 1 is made up of cutter hub 2 and handle of a knife 1, in the middle of cutter hub 2 sheet that is rectangle, the one side that contacts with handle of a knife 1 raised line 3 is arranged along its length, and top, raised line 3 cross section is triangular in shape, and raised line 3 is fixed on the cutter hub, by shop bolt 6 as shown in Figure 3.The two sides of raised line are fluted 7,8, protrude in the position-limitting pin 4,5 on raised line top on the raised line 3 in addition, and position-limitting pin 5 lower ends are connected with spring 9, and spring 9 other ends are fixed on the cutter hub 2; Handle of a knife is formed by handle 10 with seat 11 two parts, seat 11 length is equaled distance between the position-limitting pin 4,5, the seat 11 on the one side relative with handle have with cutter hub on raised line 3 corresponding breach, breach two inboards have and the corresponding flange 13,14 of raised line grooves on two sides, seat 11 two-port tops there be small gap 15,16, the size of breach and the sizableness of position-limitting pin that inwardly concaves.During assembling, will advance the raised line on the notch alignment cutter hub of seat, when process has the position-limitting pin 5 of spring, press this pin, slide, seat will be fixed between the position-limitting pin 4,5, realize that handle of a knife and cutter hub are located by connecting to position-limitting pin 4.During dismounting, the position-limitting pin 5 of band spring is pressed, handle slides crosses this pin, realizes separating of handle of a knife and cutter hub.The utility model is simple in structure, and is easy to assembly, is the claying instrument of a kind of practicality of building finishing industry.

Do not damaged for making the cutter hub edge, also for safe to carry, claying knife of the present utility model is also supporting a broach shell, this broach shell is one to be the rectangle thin plate 19 of square frame shape, size is suitable with cutter hub, thin plate two long limits and minor face two ends are upwards protected edge 17, two long limits and are protected the briquetting 18 that inwardly also is extruded with some symmetries on the edge.
