Abstract

The utility model relates to a trowel for building construction, particularly a labour saving trowel for plastering cement. A pliability of tapered concave sharp notches are arranged on one side edge of the flat plastering surface of the trowel, and both sides of the concave position of each sharp notch are respectively provided with circular arc angles. A vertical measuring apparatus and a horizontal measuring apparatus are respectively arranged on the front end surface of the handle of the trowel and above the front end of the handle. In addition, a fixing hole on the hollow back end of the handle is provided with an illuminating lamp. Therefore, the utility model has the advantages of labor saving for operation, convenient use, and high work efficiency.

Description

Spatula with sharp notch lateral margin

The utility model relates to a kind of spatula of building operations, especially refers to push away the laborsaving spatula of smearing cement.

At present; the spatula of commonly using; as shown in Figure 6; be the level and smooth edge 31 of level and smooth linearity in wipe one's face 3 both side edges of spatula flat; use spatula like this when row's par mud; there is the heavy painstaking sense that promotes difficulty in regular meeting; because cement has suitable viscosity; if use a planar object on fitting fully to promote cement; be easy to make and be found to cement and can closely stick on this plane; high viscous force will make the activity of spatula be hindered; cause the effort and the inconvenience of work, and known spatula is not provided with any level or vertical survey tool on lever 4 or its minute position, so general cement working face is not that rough situation is often arranged; must measure by other instruments, cause work to interrupt and inconvenience.

In view of this, the purpose of this utility model provides and a kind ofly is provided with the recessed sharp notch of several tapers at a flat lateral margin of wiping one's face, vertical, horizontal measuring instrument is housed in lever again, can reduces contacting of spatula and viscosity cement, can directly proofread and correct the horizontal or vertical degree of being smeared the cement face again.

The purpose of this utility model be achieved in that a kind of spatula with sharp notch lateral margin comprise flat wipe one's face, lever, it is characterized in that: be provided with several tapered recessed sharp notch at the flat lateral margin of wiping one's face of spatula, and arc chord angle is respectively established on the depression both sides of this sharp notch, above the front end face of spatula lever and front end, be respectively equipped with vertical survey instrument horizontal measuring instrument, in addition, the hollow rear end fixing hole of lever is provided with an illuminating lamp.Above-mentioned horizontal measuring instrument is one or several.

Owing to adopt such scheme: rapid operation, it is also convenient to use simultaneously, high efficiency.

Below in conjunction with drawings and Examples the utility model is further specified.

The three-dimensional exploded view of Fig. 1 the utility model exemplary embodiments.

The sharp notch partial enlarged drawing of Fig. 2 the utility model exemplary embodiments.

The lateral view of Fig. 3 the utility model exemplary embodiments.

The measurement level schematic diagram of Fig. 4 the utility model exemplary embodiments.

The measuring vertical view of Fig. 5 the utility model exemplary embodiments.

Fig. 6 commonly uses the schematic perspective view of spatula.

Among the figure: 1 flatly wipe one's face, 11 sharp notch, 12 arc chord angles, 13 level and smooth edge, 2 levers, 21 horizontal measuring instruments, 22 hang down direct testers, 23 illuminating lamps, 24 cock bodys, 25 fixing holes, 3 are flatly wiped one's face, 31 level and smooth edge, 4 levers.

Shown in Fig. 1～5, lateral margin on spatula plane 1 is provided with several and is the recessed sharp notch 11 of dimension shape, the depression both sides that this point lacks respectively make into circular-arc arc chord angle 12, the appropriate position respectively is provided with a vertical survey instrument 22 and horizontal measuring instrument 21 above the front end face of spatula lever 2 and front end, and the hollow bulb of this lever 2 ccontaining is fixed on the illuminating lamp 23 on lever 2 rear end cock bodys 24, the fixing hole 25; Several sharp notch 11 are formed flat 1 the lateral margin of wiping one's face, can make spatula promote the cement heap, and with cement when floating, reduce contacting of spatula and viscosity cement, it is more laborsaving to push away par mud, the wedge angle of sharp notch 11 and arc chord angle 12 can be kept away the lateral margin that sharp notch 11 is formed simultaneously, when floating cement, stay too dark trace track, and the level and smooth edge 13 of flat 1 another lateral margin of wiping one's face can oppositely be erased its trace track, horizontal measuring instrument 21 on lever 2 and vertical survey instrument 22 then can predict the cement face at work at any time and whether meet the requirements of level or vertical requirement, easy to use, save time.

Claims
